Fig.10 Sentry Key Immobilizer Module
SENTRY KEY IMMOBILIZER MODULE
The Sentry Key Immobilizer Module (SKIM) is the primary component of the Sentry Key
Immobilizer System (SKIS). The SKIM is located on the right side of the steering column, below the
ignition lock cylinder housing and is concealed beneath the steering column shrouds. The molded
black plastic housing for the SKIM has an integral molded plastic halo-like antenna ring that
extends from one end. When the SKIM is properly installed on the steering column, the antenna
ring is oriented around the circumference of the ignition lock cylinder housing. A single integral
connector receptacle containing six terminal pins is located on the opposite end of the SKIM
housing from the antenna ring. A stamped metal mounting bracket secured to the SKIM housing
has a U-shaped clip formation that is used to secure the unit to the right lower flange of the steering
column jacket.
The SKIM cannot be adjusted or repaired. If faulty or damaged, the entire SKIM unit must be
replaced.
The Sentry Key Immobilizer Module (SKIM) contains a Radio Frequency (RF) transceiver and a
microprocessor. The SKIM transmits RF signals to, and receives RF signals from the Sentry Key
transponder through a tuned antenna enclosed within the molded plastic antenna ring integral to
the SKIM housing. If this antenna ring is not mounted properly around the ignition lock cylinder
housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM), the Electro Mechanical Instrument Cluster (EMIC) and/or the
DRB III scan tool.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM, and is encoded to the transponder of every
Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the Sentry Key Immobilizer System (SKIS). Another
security code, called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM during SKIS
initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using the DRB III® scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The DRB III scan tool
will alert the technician during the SKIS initialization procedure if new Sentry Keys are required.
When the ignition switch is turned to the ON position, the SKIM transmits an RF signal to the
transponder in the ignition key. The SKIM then waits for an RF signal response from the
transponder. If the response received identifies the key as valid, the SKIM sends a valid key
message to the PCM over the PCI data bus. If the response received identifies the key as invalid,
or if no response is received from the key transponder, the SKIM sends an invalid key message to
the PCM. The PCM will enable or disable engine operation based upon the status of the SKIM
messages. It is important to note that the default condition in the PCM is an invalid key; therefore, if
no message is received from the SKIM by the PCM, the engine will be disabled and the vehicle
immobilized after two seconds of running.

Module, (Vehicle Antitheft) > Component Information > Locations > Page 9
The SKIM also sends SKIS indicator status messages to the EMIC over the PCI data bus to tell the
EMIC how to operate the SKIS indicator. This indicator status message tells the EMIC to turn the
indicator ON for about three seconds each time the ignition switch is turned to the ON position as a
bulb test. After completion of the bulb test, the SKIM sends indicator status messages to the EMIC
to turn the indicator off, turn the indicator ON, or to flash the indicator ON and OFF. If the SKIS
indicator flashes or stays ON solid after the bulb test, it signifies a SKIS fault. If the SKIM detects a
system malfunction and/or the SKIS has become inoperative, the SKIS indicator will stay ON solid.
If the SKIM detects an invalid key or if a key transponder-related fault exists, the SKIS indicator will
flash. If the vehicle is equipped with the Customer Learn transponder programming feature, the
SKIM will also send messages to the EMIC to flash the SKIS indicator and to generate a single
audible chime tone whenever the Customer Learn programming mode is being utilized. (Refer to
VEHICLE THEFT SECURITY - STANDARD PROCEDURE - SENTRY KEY TRANSPONDER
PROGRAMMING).
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will
store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM memory if a system
malfunction is detected. The SKIM can be diagnosed, and any stored DTC's can be retrieved using
a DRB III scan tool. Refer to the appropriate diagnostic information.

Power Door Lock Control Module: Description and Operation
DRIVER DOOR MODULE
A Driver Door Module (DDM) is used on all models equipped with power locks, power windows,
and power mirrors. The driver door module consists of a molded plastic housing that is secured
with three screws to a molded plastic switch bezel. The switch bezel is secured by metal snap clips
within an opening near the forward end of the arm rest in the driver side front door trim panel so
that the DDM can be serviced without removing the front door trim panel. Two integral connector
receptacles on the back of the DDM connect it to the vehicle electrical system through two take
outs and connectors of the left front door wire harness. The DDM houses the following switches: Power Lock Switch - The DDM includes a two-way, momentary, resistor multiplexed switch to
control the power lock system.
- Power Mirror Selector Switch - A three-position rocker switch in the DDM selects the right or left
power mirror for adjustment, or turns the power mirror system OFF.
- Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch in the DDM allows the
vehicle operator to lock out the power window switches on each passenger door so that the
passenger door power windows may be operated only from the master switches in the DDM.
- Power Window Switches - The DDM houses a two-way, momentary power window switch for the
driver side front door. This switch also has a second detent in the Down direction and internal
circuitry to provide an Auto-Down feature for the driver side front door power window. In addition to
the power window switch for its own door, the DDM houses individual master switches for each
passenger door power window.
The DDM also incorporates several green Light Emitting Diodes (LEDs) that illuminate the power
lock and power window switch paddles, and the power mirror switch directional buttons to improve
switch visibility in dark ambient lighting conditions. The DDM cannot be adjusted or repaired and, if
faulty or damaged, the entire DDM unit must be replaced.
The Driver Door Module (DDM) combines a power lock switch, a driver power window switch with
an Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit. The switches in the DDM can be diagnosed using conventional diagnostic tools and
methods.
Power Lock Switch The DDM power lock switch circuitry is connected in series between ground
and the driver door switch mux input of the Central Timer Module ( CTM). Each power lock switch
position (Lock, Unlock, and Neutral) provides a different resistance value to the CTM input, which
allows the CTM to sense the switch position. Based upon the power lock switch input, the CTM
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door and liftgate latches. The Light-Emitting Diode (LED) in the DDM power lock switch is
connected to battery current through the power window circuit breaker in the Junction Block (JB) on
a fused ignition switch output (run-acc) circuit so that the switch will be illuminated whenever the
ignition switch is in the ON or Accessory positions.
Power Window Switches The DDM power window switch circuitry is connected to battery current
through a circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc)
circuit so that the power windows will operate whenever the ignition switch is in the ON or
Accessory positions. Each two-way, momentary master passenger power window switch in the
DDM provides battery current and ground to the individual power window switches on each
passenger door so that the power window switch controls the battery current and ground feeds to
its respective power window motor. The DDM switch for the driver side front door power window is
labeled with the text "Auto" and includes an auto-down feature. When this switch is depressed to a
second momentary detent position and released, the driver door power window is automatically
operated through an internal circuit and relay to its fully lowered position. The Auto-down event is
cancelled if the switch paddle is depressed a second time in either the Up or Down direction. When
the two position window lockout switch in the DDM is depressed and latched in the lockout position,
the battery current feed to each of the individual passenger power window switches is interrupted
so that the passenger door power windows can only be operated from the master switches in the
DDM. The window lockout switch also controls the battery current feed for the LED in each
passenger power window switch so that the switch will not be illuminated when it is locked out.
Power Mirror Switches The DDM power mirror switch circuitry is connected to battery current
through a fuse in the JB on a fused B(+) circuit so that the power mirrors remain operational
regardless of the ignition switch position. A rocker type selector switch has three positions, one to
select the right mirror, one to select the left mirror, and a neutral OFF position. After the right or left
mirror is selected, one of four directional buttons is depressed to move the selected mirror Up,
Down, Right or Left. The DDM power mirror switch circuitry controls the battery current and ground
feeds to each of the four (two in each mirror head) power mirror motors. The Light-Emitting Diode
(LED) in the DDM power mirror switch is connected to battery current through the power window
circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc) circuit so that
the switch directional buttons will be illuminated whenever the ignition switch is in the ON or
Accessory positions.

Power Door Lock Control Module: Testing and Inspection
The Light-Emitting Diode (LED) illumination lamps for all of the Driver Door Module (DDM) power
window, power lock, and power mirror switches receive battery current through the power window
circuit breaker in the Junction Block (JB). If all of the LEDs are inoperative in the DDM, be certain
to diagnose the power window system before replacing the switch unit. (Refer to POWER
WINDOWS - DIAGNOSIS AND TESTING). If only one LED in the DDM is inoperative, replace the
faulty DDM. If the driver side front door power window operates in a normal manner, but the
Auto-Down feature is inoperative, replace the faulty DDM.
1. Disconnect and isolate the battery negative cable. Remove the DDM from the door trim panel.

Seat Heater Control Module: Description and Operation
Fig. 8 Heated Seat Module - Typical
HEATED SEAT MODULE
Vehicles equipped with heated seats utilize a heated seat module. The heated seat module is
located under the heated seat switches, where it is secured to a mounting bracket that is also part
of the center console. The heated seat module has a single connector receptacle that allows the
module to be connected to all of the required inputs and outputs through the center console wire
harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the ignition switch, the two heated seat switches and the two
heated seat sensors to operate and control the heated seat elements in both front seats and the
two heated seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The
heated seat module is also programmed to perform self-diagnosis of certain heated seat system
functions and provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the ignition switch. The
module is grounded at all times through a ground screw located on the drivers B-pillar. Inputs to the
module include a resistor multiplexed heated seat switch request circuit for each of the two heated
seat switches and the heated seat sensor inputs from the seat cushions of each front seat. In
response to those inputs the heated seat module controls battery current feeds to the heated seat
elements and sensors, and controls the ground for the heated seat switch indicator lamps.
When a heated seat switch (Driver or Passenger) request signal is received by the heated seat
module, the module energizes the proper indicator lamp (Low or High) in the switch by grounding
the indicator lamp circuit to indicate that the heated seat system is operating. At the same time, the
heated seat module energizes the selected heated seat sensor circuit and the sensor provides the
module with an input indicating the surface temperature of the selected seat cushion.
The Low heat set point is about 35 °C (100.4 °F), and the High heat set point is about 42 °C (107.6
°F). If the seat cushion surface temperature input is below the temperature set point for the
selected temperature setting, the heated seat module energizes an N-channel Field Effect
Transistor (N-FET) within the module which energizes the heated seat elements in the selected
seat cushion and back. When the sensor input to the module indicates the correct temperature set
point has been achieved, the module de-energizes the N-FET which de-energizes the heated seat
elements. The heated seat module will continue to cycle the N-FET as needed to maintain the
selected temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch. Refer
to Heated Seat System and Heated Seat Module in Electronic Control Modules for the location of
the proper heated seat module diagnosis and testing procedures. Also refer to the Body Diagnostic
for additional diagnosis and testing procedures.

Controller Antilock Brake: Description and Operation
CONTROLLER REAR WHEEL ANTILOCK BRAKES
Fig. 3 RWAL Cab
The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitor the RWAL brake system for proper operation.
- Control the RWAL valve solenoids.
Fig. 4 CAB/HCU
The CAB is mounted on the top of the hydraulic control unit. The CAB operates the ABS system
and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition
switch in the RUN position.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB. For axle type refer to Differential and Driveline.
System Self-test When the ignition switch is turned-ON the microprocessor RAM and ROM are
tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is
possible the DTC will not be stored in memory if the error has occurred in the RAM module were
the DTC's are

stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which
signals the RAM to store the DTC.
The CAB contains a self check program that illuminates the ABS warning light when a system fault
is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB
scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50
times. Stored faults are not erased if the battery is disconnected.
CAB Inputs The CAB continuously monitors the speed of the differential ring gear by monitoring
signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency
when it recognizes the ring gear is decelerating too rapidly. The CAB monitors the following inputs
to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB Outputs The CAB controls the following outputs for antilock braking and brake warning
information: RWAL Valve
- ABS Warning Lamp
- Brake Warning Lamp

Compressor Clutch Relay: Description and Operation
COMPRESSOR CLUTCH RELAY - FRONT
The compressor clutch relay is an International Standards Organization (ISO) micro-relay. The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay.
The compressor clutch relay is an electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the evaporator
temperature sensor, the loss of charge switch, and the pressure transducer. See Compressor
Clutch Relay in the Diagnosis and Testing for more information.
The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine
compartment. Refer to the PDC label for relay identification and location.
The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced.

Fig.12 Compressor Clutch Relay
RELAY TEST
The compressor clutch relay is located in the Power Distribution Center (PDC). Refer to the PDC
label for relay identification and location. Remove the relay from the PDC to perform the following
tests: 1. A relay in the de-energized position should have continuity between terminals 87A and 30,
and no continuity between terminals 87 and 30. If OK,
go to Step 2. If not OK, replace the faulty relay.
2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 3. If not OK, replace the faulty relay. 3. Connect a battery to terminals 85 and 86.
There should now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, see the Relay Circuit Test below. If not OK, replace the faulty relay.
RELAY CIRCUIT TEST
1. The relay common feed terminal cavity (30) is connected to fused battery feed. There should be
battery voltage at the cavity for relay terminal 30
at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required.
2. The relay normally closed terminal (87A) is not used in this application. Go to Step 3. 3. The
relay normally open terminal cavity (87) is connected to the compressor clutch coil. There should
be continuity between this cavity and the
A/C compressor clutch relay output circuit cavity of the compressor clutch coil wire harness
connector. If OK, go to Step 4. If not OK, repair the open circuit as required.
4. The relay coil battery terminal (86) is connected to the fused ignition switch output (run/start)
circuit. There should be battery voltage at the cavity
for relay terminal 86 with the ignition switch in the ON position. If OK, go to Step 5. If not OK, repair
the open circuit to the fuse in the junction block as required.
5. The coil ground terminal cavity (85) is switched to ground through the Powertrain Control Module
(PCM). There should be continuity between
this cavity and the A/C compressor clutch relay control circuit cavity of the PCM wire harness
connector C (gray) at all times. If not OK, repair the open circuit as required.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 1 Central Timer Module
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
The high-line Central Timer Module (CTM) can also control some features of the audio system
when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A
high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a
chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless
entry module, and a vehicle theft security
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Instrument Panel > Audible Warning Device
Control Module > Component Information > Diagrams > Page 126
system module in a single unit.
The high-line CTM also controls and integrates many of the additional electronic functions and
features included on models with this option. The RAZ radio receiver with a remote radio switch
option is one of the features that the CTM controls. The CTM is programmed to send switch status
messages over the J185O data bus to control the volume, seek, and pre-set station advance
functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches
located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch
status messages to the radio receiver. The electronic circuitry within the radio receiver responds to
the switch status messages it receives by adjusting the radio settings as requested.
In addition, radio receivers connected to the J1850 data bus have several audio system functions
that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more
information on DRB testing of the audio systems.
Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and
a high-line version. Whichever version of the CTM the vehicle is equipped with, it is concealed
behind the trim on the left cowl side inner panel below the instrument panel, where it is secured
with three screws. The CTM is enclosed in a molded plastic housing with three integral external
connector receptacles that connect it to the vehicle electrical system through one take out and
connector of the body wire harness, and two take outs and connectors of the instrument panel wire
harness. The base version of the CTM is used on base models of this vehicle. These base models
are not equipped with the optional power lock system, the Remote Keyless Entry (RKE) system,
the rear wiper system, the Vehicle Theft Security System (VTSS), or the remote radio controls. The
high-line version of the CTM is used on high-line vehicles that are equipped with one or more of
those options not found on base models.
The CTM utilizes integrated circuitry and information carried on the Programmable
Communications Interface (PCI) data bus network along with many hard wired inputs to monitor
many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal
circuitry and programming of the CTM allow it to supply the vehicle occupants with audible and
visual information, and to control and integrate many electronic functions and features of the
vehicle through both hard wired outputs and the transmission of electronic message outputs to
other electronic modules in the vehicle over the PCI data bus. The features that the CTM supports
or controls include the following: Automatic Door Lock - The high-line CTM provides an automatic door lock feature (also known as
rolling door locks). This is a programmable feature.
- Battery Protection - The CTM provides a battery saver feature that performs timed load shedding
whenever courtesy, reading, visor vanity, center console, glove box, or any exterior lamps are left
on with the ignition switch in the OFF position.
- Central Locking - The high-line CTM on vehicles equipped with the optional Vehicle Theft Security
System (VTSS) includes a central locking/ unlocking feature.
- Chimes - All versions of the CTM provide chime service and beep request service through an
integral chime tone generator.
- Door Lock Inhibit - The high-line CTM provides a power door lock inhibit feature.
- Enhanced Accident Response - The high-line CTM provides an optional enhanced accident
response feature. This is a programmable feature.
- Exterior Light Features - The CTM provides control of park lamps, fog lamps, and headlamps.
This includes support for optical horn (also known as flash-to-pass), headlamp time delay, daytime
running lamps (DRL - Canada only), and battery saver features.
- Interior Light Features - The CTM provides control of courtesy lamps, dome lamps, and the liftgate lamp. This includes support for a timed illuminated entry with fade-to-OFF, interior lighting
delay, courtesy illumination defeat, and battery saver features.
- Intermittent Wipe Control - The CTM provides control of the intermittent wipe delay, and
wipe-after-wash features for the front wiper and washer system. The high-line CTM also provides
these same features for the optional rear wiper and washer system.
- Panic Mode - The high-line CTM provides support for the optional RKE system panic mode
including horn chirp, headlamp flash, and park lamp flash features.
- Power Lock Control - The high-line CTM provides the optional power lock system features,
including support for the automatic door lock and door lock inhibit modes.

Hard wired circuitry connects the CTM to the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained
by many different methods. These circuits may be connected to each other, to the vehicle electrical
system and to the CTM through the use of a combination of soldered splices, splice block
connectors, and many different types of wire harness terminal connectors and insulators.
All versions of the CTM for this model are serviced only as a complete unit. Many of the electronic
features in the vehicle controlled or supported by the CTM are programmable using the DRB III
scan tool. In addition, the CTM software is Flash compatible, which means it can be reprogrammed
using Flash reprogramming procedures. However, if any of the CTM hardware components are
damaged or faulty, the entire CTM unit must be replaced. The hard wired inputs or outputs of all
CTM versions can be diagnosed using conventional diagnostic tools and methods; however, for
diagnosis of the CTM or the PCI data bus, the use of a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

The microprocessor-based Central Timer Module (CTM) monitors many hard wired switch and
sensor inputs as well as those resources it shares with other electronic modules in the vehicle
through its communication over the Programmable Communications Interface (PCI) data bus
network. The internal programming and all of these inputs allow the CTM microprocessor to
determine the tasks it needs to perform and their priorities, as well as both the standard and
optional features that it should provide. The CTM programming then performs those tasks and
provides those features through both PCI data bus communication with other electronic modules
and through hard wired outputs through a number of driver circuits, relays, and actuators. These
outputs allow the CTM the ability to control numerous accessory systems in the vehicle.
The CTM operates on battery current received through two fuses in the Junction Block (JB) on two
non-switched fused B(+) circuits, a fused ignition switch output (run-start) circuit, and a fused
ignition switch output (run-acc) circuit. This arrangement allows the CTM to provide some features
regardless of the ignition switch position, while other features will operate only with the ignition
switch in the Accessory, ON, and/or Start positions. The CTM receives ground through its
connector and take out of the instrument panel wire harness on three separate ground circuits. Two
of these circuits are grounded through a take out of the instrument panel wire harness with an
eyelet terminal connector that is secured by a nut to a ground stud on the left inner cowl side panel
near the CTM, while the third circuit is grounded through a take out of the instrument panel wire
harness with an eyelet terminal connector that is secured by a ground screw to the left side of the
floor panel transmission tunnel near the Airbag Control Module (ACM).
The CTM monitors its own internal circuitry as well as many of its input and output circuits, and will
store a Diagnostic Trouble Code (DTC) in electronic memory for any failure it detects. These DTCs
can be retrieved and diagnosed using a DRB III scan tool. Refer to the appropriate diagnostic
information.

The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.

Horn Relay: Description and Operation
The horn relay is a electromechanical device that switches battery current to the horn when the
horn switch grounds the relay coil. The horn relay is located in the Junction Block (JB), on the left
end of the instrument panel in the passenger compartment. If a problem is encountered with a
continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the
JB until further diagnosis is completed. See the fuse and relay layout label affixed to the inside
surface of the fuse access panel for horn relay identification and location.
The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to
the ISO specifications have common physical dimensions, current capacities, terminal patterns,
and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO
relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity
is lower, and the physical dimensions are smaller than those of the conventional ISO relay.
The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it
draws the movable contact away from the normally closed fixed contact, and holds it against the
other (normally open) fixed contact.
When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the
normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil
in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, Refer TO ELECTRICAL, RESTRAINTS
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER
PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
1. Remove the horn relay from the JB. (Refer to HORN RELAY - REMOVAL) for the procedures. 2.
A relay in the de-energized position should have continuity between terminals 87A and 30, and no
continuity between terminals 87 and 30. If OK,
go to Step 3. If not OK, replace the faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace the faulty relay. 4. Connect a battery to terminals 85 and 86. There
should now be continuity between terminals 30 and 87, and no continuity between terminals 87A
and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the faulty relay.
Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage
and should be hot at all times. If OK, go to Step 2. If not OK, repair
the open circuit to the fuse in the PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the
energized position. This terminal supplies battery
voltage to the horn(s). There should be continuity between the cavity for relay terminal 87 and the
horn relay output circuit cavity of each horn wire harness connector at all times. If OK, go to Step 4.
If not OK, repair the open circuit to the horn(s) as required.
4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is connected to
battery voltage and should be hot at all times. Check
for battery voltage at the cavity for relay terminal 86. If OK, go to Step 5. If not OK, repair the open
circuit to the fuse in the PDC as required.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded
through the horn switch when the horn switch is
depressed. On vehicles equipped with the Remote Keyless Entry (RKE) system, the horn relay coil
ground terminal can also be grounded by the Central Timer Module (CTM) in response to certain
inputs related to the RKE system or the Vehicle Theft Security System. Check for continuity to
ground at the cavity for relay terminal 85. There should be continuity with the horn switch
depressed, and no continuity with the horn switch released. If not OK, (Refer to HORN SWITCH DIAGNOSIS AND TESTING).

Relay Box: Description and Operation
Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Central Timer Module: Vehicle Damage Warnings
Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could
damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of
the original problem more difficult,
Road Testing A Complaint Vehicle
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE
REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB III SCREEN
WHILE IN MOTION. DO NOT HANG THE DRB III FROM THE REAR VIEW MIRROR OR

Description and Operation > Sytem Description
Central Timer Module: Description and Operation Sytem Description
The body system on the 2001 DN consists of a combination of modules that communicate over the
PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus,
information about the operation of vehicle components and circuits is relayed quickly to the
appropriate module(s). All modules receive all the information transmitted on the bus even though
a module may not require all information to perform its function. It will only respond to messages
"addressed" to it through a binary coding process. This method of data transmission significantly
reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the
information about the functioning of all the systems is organized, controlled, and communicated by
the PCI bus, which is described in the vehicle communication of this general information.

For additional information on the Base CTM refer to Instrument Panel, Gauges and Warning
Indicators / Audible Warning Device. See: Instrument Panel, Gauges and Warning
Indicators/Audible Warning Device
AIRBAG SYSTEM
The airbag system is designed to provide increased driver and passenger protection if the vehicle
is involved in a front end collision. The system is most effective when used in conjunction with the
seat belt system.
The Airbag Control Module (ACM) is an electronic module that monitors the airbag system for
proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and
contains the sensor and actuator that is responsible for airbag deployment. There are no external
impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck
at the bottom of the instrument panel. It is located forward of the console. The ACM provides
diagnostic information (DTCs) to the technician through the DRB III via the PCI bus. Some circuits
are tested continuously; others are checked only under certain circumstances. The warning lamp is
driven with messages relayed to the Electro/Mechanical Instrument Cluster (EMIC) from the ACM
via the PCI bus.
The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be
observed by the customer. Whenever the ignition key is turned to the "run" or "start" position, the
airbag control module performs a lamp check by turning the AIRBAG warning lamp ON for 6 - 8
seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to
be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the
system or the circuit that operates the lamp may be shorted to ground. If the lamp comes ON and
stays ON for a period longer than 6 - 8 seconds, then goes OFF, there is usually an intermittent
problem in the system.
WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT.
Seat Belt Tensioner
Front seat belt systems incorporate Tensioner Modules (SBT). At the onset of an impact event
each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to
rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact
will be reduced as will the likelihood of contacting interior components. After an impact that deploys
the airbag, the seat belt tensioner assembly must be replaced.
The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and
stored DTC's if any problem is found.
Airbag Diagnostic Trouble Codes
Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,
diagnostic priority should be given to the active codes.
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic
test procedures contain step-by-step instructions for determining the cause of the trouble codes. It
is not necessary to perform all of the tests in this book to diagnose an individual code.
Always begin by reading the diagnostic trouble codes using the DRB III.
Active diagnostic trouble codes for the airbag system are not permanent and will change the
moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes
are used as a diagnostic tool.
Active Codes
The code becomes active as soon as the malfunction is detected and stored after one minute of
occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going
malfunction. This means that the defect is currently there every time the airbag control module
checks that circuit/function. It is impossible to erase an active code; active codes automatically
erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is
detected, the airbag lamp remains lit for a minimum

Description and Operation > Sytem Description > Page 232
of 12 seconds or as long as the malfunction is present.
Stored Codes
Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or
when the ignition is turned OFF. The exception is the "Loss of Ignition Run Only" code which is an
active code only.
A "stored" code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
When a trouble code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
The minimum time shown for any code will be one minute, even if the code was actually present for
less than one minute. Thus, the time shown for a code that was present for two minutes 13
seconds, for example, would be three minutes.
If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the
malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be
initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same
malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If
the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset
and the diagnostic trouble code will continue to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code
diagnostic test will not locate the source of the problem. In this case, the stored code can indicate
an area to inspect.
If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire
harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes
periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
AUDIO SYSTEM
The factory installed radio receiver communicates on the Programmable Communication Interface
(PCI) data bus network through a separate two-way wire harness connector. This is used for the
remote radio switches that are mounted to the steering wheel, and also used for radio diagnosis
with the DRB III.
The remote radio switches are resistor multiplexed units that are hard wired to the CTM through the
clockspring. The CTM monitors the status of the remote radio switches and sends the proper
switch status messages on the PCI data bus network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by
adjusting the radio settings as requested.
When troubleshooting output shorts or "output" error messages, the following applies: On radios
without an external amplifier, the term "output" refers to the path between the radio and the
speaker. This type of circuit can be monitored all the way through the speaker connections by the
radio assembly. When the radio displays a shorted output DTC with this type of system, the
speaker, radio or wiring could be at fault. The output DTC could refer to a front or rear output or a
left or right output. The reason for the difference is the pairing of the output sections of the radio.
Some are paired left and right, others are paired front and rear.
On radios with an external amplifier, the term "output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of monitoring only this portion and can tell nothing
about the circuit between the amplifier and the speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit. A faulty speaker could not cause this DTC.
CENTRAL TIMER MODULE
The Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or
Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.
The Base and Highline CTM provides the following features: Battery Saver Functions For Exterior and Interior Lamps
- Cargo Lamps
- Chime Warning
- Courtesy Lamps
- Dome Lamps
- Dome Defeat
- Door Ajar Switch Status
- Fog Lamps
- Head Lamp Time Delay
- Intermittent Wiper Controls
- Low and High Beam Head Lamps

- Vehicle Theft Alarm (VTSS)
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
CHIME SYSTEM
The chime system is built into the CTM. There are two chime rates, Low: 50 chimes per minute for
reminders and High: 180 chimes per minute for serious conditions that require immediate attention.
The high rate chime sounds when the key is left in the ignition and the driver's door is open or if the
headlights or the courtesy lights are left on. The low rate chime sounds for any of the other
conditions. There is a variable rate feature that allows the chime to sound continuously for key-in
and headlamp warning as long as the door is open. The seat belt warning chime is activated for six
seconds, and all other chime conditions will activate the chime once at the same time the warning
light on the cluster is illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
COMPASS MINI-TRIP COMPUTER (CMTC)
This system, located in the overhead console, displays information on outside temperature,
compass direction and trip information.
Compass and Temperature Display This display provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is facing.
Trip Odometer (ODO) Shows the distance traveled since the last reset.
Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or
L/100 Km since the last reset.
Instant Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100 Km.
Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel
remaining in the tank. This is calibrated using the MPG for the last few minutes.
Elapsed Time (ET) Shows the accumulated ignition ON time since the last reset.
Step Button Press this button to cycle through all the mini-trip computer displays.
US/M Button Press this button to convert all vehicle displays from US to Metric to US.
To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds
and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,
ECO, ET) is currently being displayed.

Automatic Compass Calibration This compass is self calibrating which eliminates the need to
manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL
symbol will be displayed. After completing three 360' turns in an area free from large metal or
metallic objects, the CAL symbol will turn OFF and the compass will function normally.
Compass Variance Compass Variance is the difference between Magnetic North and Geographic
North. In some areas of the country, the difference between Magnetic and Geographic North is
great enough to cause the compass to give false readings. If this occurs, the compass variance
must be set.
To Set the Variance Turn the ignition ON and set display to Comp./Temp. while pressing the US/M
button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the
last variance zone number will be displayed. Press the US/Metric Button to select the proper
variance zone as shown on the map. Press the Step button to set the new variance zone and
resume normal operation.
ELECTRO/MECHANICAL INSTRUMENT CLUSTER (EMIC)
The Instrument Cluster contains a Fuel, Voltmeter, Coolant Temp, and Oil Pressure gauge, a
Tachometer and a Speedometer. With the exception of the Voltmeter, the cluster positions the
gauges with PCI Bus messages received from the PCM. The Voltmeter operates directly off of the
Fused B+ Switched Ignition Output circuit that supplies ignition voltage for the cluster.
The Instrument Cluster also contains warning indicators that are illuminated by hard wired inputs or
by messages received from other modules on the PCI Bus.
The Trip/Total Odometer is a Vacuum Fluorescent Display (VF) that is controlled by PCI Bus
messages received from the PCM.
The cluster illumination lamps are hard wired in the Instrument Cluster. When the Park or
Headlamps are turned ON, the cluster receives a dimmed battery feed from the Headlamp Switch.
The cluster I/O Processor controls the VF display dimming and also sends dimming level
messages on the PCI Bus.
The EMIC will communicate with the DRB III to display PCI Engine Info, PCI Bus Info, and certain
input/outputs. Cluster diagnostic capabilities that the DRB III will actuate are limited to the Cluster
Calibration Points for the gauges. The DRB III can also extract active and stored Diagnostic
Trouble Codes (DTC) from the Instrument Cluster.
The EMIC is also capable of performing a diagnostic Self-Test that is actuated by depressing and
holding the Odometer trip reset stalk while cycling the ignition from the OFF to the ON position.
After the cluster Odometer displays CHEC, releasing the reset stalk begins the test. The cluster will
then position all of the gauges at specified calibration points and will illuminate all the PCI Bus
controlled indicators. The cluster will also illuminate each segment of the VF display.
The EMIC can verify communications with the PCM, ID the module, or change the country code
using the DRB III.
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI
bus to the CTM module to unlock the doors. The interior lights will be turned ON when the vehicle
speed message on the PCI bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time
following the deployment. Once the ignition key has been cycled to the "OFF" position, normal
operation will resume.
EXTERIOR LIGHTING
The low and high beam headlamps are controlled directly by an output from the Central Timer
Module (CTM). The park lamps and fog lamps (on vehicle so equipped) are controlled via external
relays that are energized by the CTM. The headlamp switch provides the control signal through the
multifunction switch to the CTM, which indicates low or high beam operation.
The Optical Horn (Flash to Pass) feature operates both the high beam and low beam headlamps.
The CTM provides the Headlamp Time Delay feature. To start the delay, turn the ignition OFF
while the headlamps are ON. Then turn the headlamp switch to the OFF position. This has to be
done within 45 seconds of the ignition being turned OFF. The headlamps will remain ON for 60 ± 5
seconds. If during this delay period the headlamp switch is turned ON and then OFF, or ignition
switch is turned ON delay will be canceled and they will turn OFF immediately. During the delay
period, only headlamps are turned ON and park lamps/fog lamps are turned OFF.
The CTM also provides battery protection to avoid wearing down the battery if the customer leaves
the park lamps or headlamps ON for extended period of time with the ignition OFF. If the park
lamps or headlamps remain ON for more than 5 minutes while the ignition is OFF, the headlamps
and park lamps shall be turned off and the input causing the lamps to be ON will be ignored until
the input is corrected. Once the 5 minute timeout has extinguished the headlamps and park lamps,
any change in the ignition switch, door ajar switches, headlamps switch or park lamp switch will
reset the 5 minute timer and return the headlamps and park lamps to normal operation.

HEATING & A/C SYSTEM
The all-new heating and air conditioning system for DN provides more heating and cooling capacity
than in previous years. Depending on the model, either a Dual-Zone Air Conditioning System or a
Three-Zone Air Conditioning System is currently available in these vehicles.
Air Distribution (Front)
The front compartment HVAC unit has four fully adjustable instrument panel outlets. Side-window
demister outlets in the instrument panel eliminate the need for door ducts and door-to-instrument
panel seals. A single central mounted outlet delivers air for defrosting the windshield. Two outlets,
one on each side of the center console underneath the instrument panel, provide airflow to the
driver floor area and to the front seat passenger floor area. While two additional outlets, one on
each side of the center console near the rear of the front seats, distribute both heated and cooled
air across the floor to the intermediate seat passengers. Ducts in the center of the vehicle
underneath the carpet deliver air from the front compartment HVAC unit to the two intermediate
passenger outlets.
Door Actuator Control
A simplified control system for operation of the mode, recirculation, and temperature control
actuators provides positive positioning without the complexity of feedback from position sensors.
The A/C - Heater Control Module knows the number of operating actuator revolutions required for
full door travel as well as the number of actuator commutator pulses per revolution. Using these
parameters, the A/C - Heater Control Module runs the actuator for the number of commutator
pulses that correspond to the desired door position. To maintain accuracy, the system recalibrates
itself periodically at known zero and full travel conditions.
The dual sliding Blend switches have multiple detents to control the full range of temperature that
the system can produce in any mode. On Dual-Zone systems, the upper slide pot controls the
driver-side blend door and the lower slide pot controls the passenger-side blend door. On
Three-Zone systems, the upper slide pot controls the driver-side blend door, while the lower slide
pot controls the passenger-side blend door and the rear A/C - heater unit blend door.
The single rotary Mode switch has 12 detents to either direct airflow to the panel outlets, to a mix of
floor and panel outlets, to the floor outlets, to a mix of floor and defrost outlets, or to the defrost
outlet. Rotating the Mode switch to either of the two MAX positions results in the A/C - Heater
Control Module sending a signal to the recirculation actuator to close the fresh-air door. While
rotating the Mode switch to any other position results in the A/C - Heater Control Module sending a
signal to the recirculation actuator to open the fresh-air door.
When the Blower switch is OFF, the A/C - Heater Control Module closes the fresh-air door to
prevent outside air from entering the vehicle. On Three- Zone systems, the Mode switch also
controls the rear A/C - heater unit mode door, which directs rear airflow either to the right quarter
trim panel outlet or to the overhead outlets.
Front Blower Control
The front blower circuitry employs a new resistor technology to control front blower speed. Called
the "credit card" resistor, the device looks much like its name in that it is thin and compact like a
credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the
front HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card
resistor offers much less airflow restriction.
A/C Operation
The A/C - Heater Control Module monitors the temperature of the evaporator to keep it just above
freezing for maximum cooling and dehumidification. A thermistor (temperature variable resistor)
placed between the evaporator fins provides the signal for the control. The Powertrain Control
Module (PCM) cycles the compressor on and off with a signal from the A/C - Heater Control
Module.
Heater Operation
To assist the HVAC system in maintaining a consistent and optimum heat output at low vehicle
speeds, an electric coolant pump operates under specific conditions to keep a steady flow of hot
coolant circulating through the heater circuit. The A/C - Heater Control Modules controls the
operation of the electric coolant pump. The pump runs when all of the following conditions are met:
When the vehicle's speed is below 27 Km/h (17 mph), the coolant temperature is between 65.5 °C
and 110 °C (150 °F and 230 °F), and the blend control is set above 60% reheat. The A/C - Heater
Control Module turns the pump OFF if any one of the following conditions occur: The vehicle speed
rises above 48.3 Km/h (30 mph). The coolant temperature drops below 65.5 °C (150 °F). The
coolant temperature rises above 110 °C (230 °F). The blend control is set below 60% reheat.
A/C - Heater Control (Rear)
The Three-Zone system allows the intermediate seat occupants to regulate the air temperature and
the fan speed of the rear unit from the rotary controls on the headliner mounted Rear A/C - Heater
Control.
HVAC Diagnostics
The A/C - Heater Control Module is fully addressable with the DRB III. Two of the Control Module's
diagnostic capabilities that the DRB III will actuate include the A/C Cool down Test to test A/C
system performance and the HVAC Door Recalibration Test to determine actuator travel span.
After performing either test, the Control Module will display one or more messages on the DRB III
screen. The message will indicate either that the HVAC system passed the test or that there is a
fault currently active in the HVAC system. The DRB III can also extract active and stored
Diagnostic Trouble Codes (DTCs) from the control module. Active DTCs are faults that currently
exit in the HVAC system. Stored DTCs are faults that occurred in the HVAC system since the
control module received the last "clear diagnostic info" message.
INTERIOR LIGHTING

Description and Operation > Sytem Description > Page 236
The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module
(CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when
either the dome lamp switch is turned ON or a door is opened. The courtesy lamps will fade to OFF
immediately when all doors are closed with the dome lamp switch in the OFF position.
The illuminated entry feature operates under the following conditions: RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned ON
Once activated, the illuminated entry will "fade to OFF" after 3 to 5 seconds under the following
conditions: All doors are closed and: RKE "lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will not reset timer.
Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and
the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp
position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps.
The Interior lamp defeat feature will not allow any interior lamp to be turned ON. This is
accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps due to the following.
Leaving a door open, dome lamp switch ON, reading/vanity lamp switch ON or glove box door
open for more than 15 minutes while the ignition is OFF.
POWER DOOR LOCKS/REMOTE KEYLESS ENTRY
The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key
fob or interior switch.
Vehicles that are equipped with the Vehicle Theft Security System will also have the central locking
feature. With the central locking feature, when the cylinder lock switch is turned to the lock position
all the doors will lock. For unlocking, if the key is turned to the unlock position once, only that door
will unlock. If the key is then turned a second time to the unlock position, all the doors will unlock.
There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is
OFF and the key is in the ignition.
Automatic or "rolling locks" are included as a programmable feature. If the vehicle is moving
approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the
PCM will send this info to the CTM via the PCI bus) indicating acceleration, the CTM will cycle the
lock actuators to lock the doors.
The highline CTM provides for Remote Keyless Entry (RKE)
The RKE system is placed in the programming mode by the DRB III, or by the customer program
features. The system will store up to four key fob codes. Two fobs are supplied with the truck,
additional fobs may be purchased through the parts department. Through the DRB III, erasing and
programming of one key fob without deleting the others is possible. If the key fob is stolen, all the
fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense
of security.
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network
capable of supporting binary encoded messages shared between multiple modules. The PCI bus
circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added
to the yellow in order to distinguish between different module connections. The modules are wired
in parallel. Connections are made in the harness using a splice.
The splice called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit. The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 237
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The
bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and
a half volts when modules are transmitting.
The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only
voltage present when the modules transmit and the message length is only about 500 milliseconds,
it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred
method is to use the DRB III lab scope. The 12v square wave selection on the 20-volt scale
provides a good view of the bus activity. Voltage on the bus should pulse between zero and about
seven and a half volts. Refer to the figure for some typical displays.
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Powertrain Management > Relays and Modules Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 238
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.
VEHICLE THEFT SECURITY SYSTEM
The VTSS system monitors the door ajar switches, and ignition switch to detect unauthorized entry
into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system
to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to
start the engine with a non-programmed SKIM key, it will start and stall. If the trigger condition is
still present, the lights will continue to flash for an additional 15 minutes, after which the system will
stop pulsing the lights and return to the "armed" state. The cause of the last 4 alarm triggers is
stored by the CTM and may be retrieved by the DRB III. The system may be disarmed by either an
unlock command from a valid RKE key fob by using a key in either door, or by using a valid SKIM
key in the ignition. The door key cylinders are equipped with disarm switches. There is also a VTSS
lamp on the dash that provides information to the driver about the state of the vehicle theft system.
WINDSHIELD WIPER SYSTEM
The DN truck is equipped with speed sensitive intermittent wipers. The low and high speeds are
controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by
the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as
selected by the driver, an immediate wipe of the windshield takes place and the new delay interval
is implemented.

Central Timer Module: Symptom Related Diagnostic Procedures
Non-Trouble Code Procedures
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module.
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING

Central Timer Module: Scan Tool Testing and Procedures
DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB III will display one of only two error messages:
User-Requested WARM Boot (Press MORE and NO at the same time)
User-Requested COLD Boot (Press MORE and YES at the same time)
If the DRB III should display any other error message, record the entire display and call the
S.T.A.R. Center for information and assistance.
DRB III DOES NOT POWER UP
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a
bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts
is required to adequately power the DRB III.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle
battery is fully charged, and inoperative DRB III may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate body diagnostics.
DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this
condition
SOME DISPLAY ITEMS READ "---"
This is caused by scrolling the DRB III display a single line up or down. The line which was scrolled
onto the screen might read "---". Use the Page

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Powertrain Control Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Powertrain Control Module: Description and Operation
Fig. 9 PCM Location
POWERTRAIN CONTROL MODULE
The Powertrain Control Module (PCM) is located in the engine compartment. The PCM is referred
to as JTEC.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed and the brake switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

MODES OF OPERATION
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (O2S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (O2S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the O2S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation: Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration

Diagrams > Page 313
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch ON, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
Ignition Switch (KEY-ON) Mode This is an Open Loop mode. When the fuel system is activated by
the ignition switch, the following actions occur: The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD relay. The 02S sensor input is not used
by the PCM to calibrate air-fuel ratio during this mode of operation.
Engine Start-Up Mode This is an Open Loop mode. The following actions occur when the starter
motor is engaged.The PCM receives inputs from: Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Starter motor relay
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
Engine Warm-Up Mode This is an Open Loop mode. During engine warmup, the PCM receives
inputs from: Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto.trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the clutch relay. This is done if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
Idle Mode When the engine is at operating temperature, this is a Closed Loop mode. At idle speed,
the PCM receives inputs from: Air conditioning select signal (if equipped)

- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Battery voltage

Based on these inputs, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.It
also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Cruise Mode When the engine is at operating temperature, this is a Closed Loop mode. At cruising
speed, the PCM receives inputs from: Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (O2S) sensors
Based on these inputs, the following occurs: -
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control ('AC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Acceleration Mode This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle
position or MAP pressure as a demand for increased engine output and vehicle acceleration. The
PCM increases injector pulse width in response to increased throttle opening.
Deceleration Mode When the engine is at operating temperature, this is an Open Loop mode.
During hard deceleration, the PCM receives the following inputs. Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed sensor
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor.

injector ON and OFF. The PCM ignores the oxygen sensor input signal and provides a
predetermined amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
ignition switch OFF Mode When ignition switch is turned to OFF position, the PCM stops operating
the injectors, ignition coil, ASD relay and fuel pump relay.
5 VOLT SUPPLIES
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply: supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply: supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (if equipped with an RE
automatic transmission).
IGNITION CIRCUIT SENSE
This circuit ties the ignition switch to the Power- train Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage ON the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
POWER GROUND
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads: Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
SENSOR RETURN
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors. Refer
to Power Grounds for more information.
SIGNAL GROUND
Signal ground provides a low noise ground to the data link connector.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM. Whenever the ignition key
is turned ON, the electric fuel pump will operate. But, the PCM will shutdown the ground circuit to
the fuel pump relay in approximately 1-3 seconds unless the engine is operating or the starter
motor is engaged.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) is secured with screws to a mount welded onto the top of the
floor panel transmission tunnel behind the instrument panel center support bracket in the
passenger compartment of the vehicle. The ACM contains an electronic microprocessor, an
electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor.
The ACM is connected to the vehicle electrical system through a take out and connector of the
instrument panel wire harness.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the ACM contains the airbag system logic circuits, and it monitors and
controls all of the airbag system components. The ACM also uses On-Board Diagnostics (OBD)
and can communicate with other electronic modules in the vehicle as well as with the DRB III scan
tool using the Programmable Communications Interface (PCI) data bus network. This method of
communication is used for control of the airbag indicator in the ElectroMechanical Instrument
Cluster (EMIC) and for airbag system diagnosis and testing through the 16-way data link connector
located on the lower left edge of the instrument panel. (Refer to INSTRUMENT CLUSTER/AIRBAG
INDICATOR - OPERATION). The ACM microprocessor continuously monitors all of the airbag
system electrical circuits to determine the system readiness. If the ACM detects a monitored
system fault, it sets an active Diagnostic Trouble Code (DTC) and sends messages to the EMIC
over the PCI data bus to turn ON the airbag indicator. If the airbag system fault is still present when
the ignition switch is turned to the OFF position, the DTC is stored in memory by the ACM.
However, if a fault does not recur for a number of ignition cycles, the ACM will automatically erase
the stored DTC.
The ACM receives battery current through two circuits, on a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and on a fused ignition switch output (run-start) circuit
through a second fuse in the JB. The ACM is grounded through a ground circuit and take out of the
instrument panel wire harness. This take out has a single eyelet terminal connector secured by a
ground screw to the left side of the floor panel transmission tunnel near the ACM in the passenger
compartment. Therefore, the ACM is operational whenever the ignition switch is in the Start or ON
positions. The ACM also contains an energy-storage capacitor. When the ignition switch is in the
Start or ON positions, this capacitor is continually being charged with enough electrical energy to
deploy the airbags for up to one second following a battery disconnect or failure. The purpose of
the capacitor is to provide backup airbag system protection in case there is a loss of battery current
supply to the ACM during an impact. The capacitor is only serviced as a unit with the ACM.
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensor is an accelerometer that senses the rate of vehicle deceleration, which
provides verification of the direction and severity of an impact. A pre-programmed decision
algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the
impact sensor indicates an impact that is severe enough to require airbag system protection. When
the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags and
the seat belt tensioners. The safing sensor is an electromechanical sensor within the ACM that is
connected in series between the ACM microprocessor deployment circuit and the airbags/seat belt
tensioners. The safing sensor is a normally open switch that is used to verify or confirm the need
for an airbag deployment by detecting impact energy of a lesser magnitude than that of the
electronic impact sensor, and must be closed in order for the airbags/seat belt tensioners to deploy.
The impact sensor and safing sensor are calibrated for the specific vehicle, and are only serviced
as a unit with the ACM.

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

Starter Relay: Testing and Inspection
Fig. 11 Starter Relay
The starter relay (Fig. 11) is located in Power Distribution Center (PDC). Refer to PDC cover for
relay identification and location.
1. Remove starter relay from PDC. 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12V battery to terminals 85 and 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage
and should be hot at all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to ON position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 397
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 398
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 399
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 400
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Transmission Control Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation
Troubleshooting Tests
Fig.6 Electrostatic Discharge Symbol
STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES
All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When
handling any component with this symbol, comply with the following procedures to reduce the
possibility of electrostatic charge build up on the body and inadvertent discharge into the
component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Transmission Control Module: Description and Operation
Fig. 13 Transmission Control Module Location
The Transmission Control Module (TCM) is located in the engine compartment on the right
(passenger) side and is mounted to the radiator core support (Fig. 13).
The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 419
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Relays and Modules > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 420
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Driving Conditions
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the
following chart to determine the appropriate operation expected, depending on driving conditions.

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Wiper Control Module: Description and Operation
FRONT WIPER MODULE
The wiper module is secured with screws through four rubber grommet-type insulators to the cowl
plenum panel and concealed within the cowl plenum area beneath the cowl plenum cover/grille
panel. The ends of the wiper pivot shafts that protrude through dedicated openings in the cowl
plenum cover/grille panel to drive the wiper arms and blades are the only visible components of the
wiper module. The wiper module consists of the following major components: Bracket - The wiper module bracket consists of a long tubular steel main member that has a
stamped pivot bracket formation near each end where the two wiper pivots are secured. A stamped
steel mounting plate for the wiper motor is secured with welds near the center of the main member.
- Crank Arm - The wiper motor crank arm is a stamped steel unit that has a slotted hole on the
driven end that is secured to the wiper motor output shaft with a nut, and has a ball stud secured to
the drive end.
- Linkage - The two wiper linkage members are each constructed of stamped steel. A driver side
drive link with a plastic socket-type bushing in the left end, and a plastic sleeve-type bushing in the
right end. Socket bushing is snap-fit over the pivot ball stud on the left pivot, while the sleeve
bushing is fit over the longer wiper motor crank arm pivot stud. The passenger side drive link has a
plastic socket-type bushing on each end. One end of this drive link is snap-fit over the pivot ball
stud on the right pivot, while the other end is snap-fit over the exposed end of the longer ball stud
on the wiper motor crank arm.
- Motor - The wiper motor is secured with three screws to the motor mounting plate near the center
of the wiper module bracket. The wiper motor output shaft passes through a hole in the module
bracket, where a nut secures the wiper motor crank arm to the motor output shaft. The two-speed
permanent magnet wiper motor features an integral transmission, an internal park switch, and an
internal Positive Temperature Coefficient (PTC) circuit breaker.
- Pivots - The two wiper pivots are secured to the ends of the wiper module bracket. The crank
arms that extend from the bottom of the pivot shafts each have a ball stud on their end. The upper
end of each pivot shaft where the wiper arms will be fastened each has an externally serrated drum
secured to it.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or
damaged, the entire wiper module unit must be replaced.
The wiper module operation is controlled by the vehicle operator through battery current inputs
received by the wiper motor from the multi-function switch on the steering column. The wiper motor
speed is controlled by current flow to either the low speed or the high speed set of brushes. The
park switch is a single pole, single throw, momentary switch within the wiper motor that is
mechanically actuated by the wiper motor transmission components. The park switch alternately
closes the wiper park switch sense circuit to ground or to battery current, depending upon the
position of the wipers on the glass. This feature allows the motor to complete its current wipe cycle
after the wiper system has been turned OFF, and to park the wiper blades in the lowest portion of
the wipe pattern. The automatic resetting circuit breaker protects the motor from overloads. The
wiper motor crank arm, the two wiper linkage members, and the two wiper pivots mechanically
convert the rotary output of the wiper motor to the back and forth wiping motion of the wiper arms
and blades on the glass.

Wiper Relay: Description and Operation
FRONT WIPER RELAY
The front wiper relay (or intermittent wipe relay) is located in the Power Distribution Center (PDC)
near the battery in the engine compartment. See the fuse and relay layout label affixed to the inside
surface of the PDC cover for front wiper relay identification and location. The front wiper relay is a
conventional International Standards Organization (ISO) micro relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. The relay is contained within a small, rectangular, molded plastic housing. The
relay is connected to all of the required inputs and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of the relay base. The ISO designation for each
terminal is molded into the base adjacent to the terminal. The ISO terminal designations are as
follows: 30 (Common Feed) - This terminal is connected to the movable contact point of the relay.
- 85 (Coil Ground) - This terminal is connected to the ground feed side of the relay control coil.
- 86 (Coil Battery) - This terminal is connected to the battery feed side of the relay control coil.
- 87 (Normally Open) - This terminal is connected to the normally open fixed contact point of the
relay.
- 87A (Normally Closed) - This terminal is connected to the normally closed fixed contact point of
the relay.
The front wiper relay cannot be adjusted or repaired. If the relay is damaged or faulty, it must be
replaced.
The front wiper relay (or intermittent wipe relay) is an electromechanical switch that uses a low
current input from the Central Timer Module ( CTM) to control a high current output to the low
speed brush of the front wiper motor. The movable common feed contact point is held against the
fixed normally closed contact point by spring pressure. When the relay coil is energized, an
electromagnetic field is produced by the coil windings. This electromagnetic field draws the
movable relay contact point away from the fixed normally closed contact point, and holds it against
the fixed normally open contact point. When the relay coil is de-energized, spring pressure returns
the movable contact point back against the fixed normally closed contact point. A resistor or diode
is connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil
collapses.
The front wiper relay terminals are connected to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC). The inputs and outputs of the front wiper relay
include: The common feed terminal (30) is connected to the front wiper motor low speed brush through the
wiper control circuitry of the multi-function switch on the steering column. When the front wiper
relay is de-energized, the common feed terminal is connected to the front wiper park switch output
through the CTM on the front wiper park switch sense circuit. The front wiper park switch output
may be battery current (wipers are not parked), or ground (wipers are parked). When the front
wiper relay is energized, the common feed terminal of the relay is connected to battery current from
a fuse in the Junction Block (JB) through a fused ignition switch output (run-acc) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the front wiper relay based upon its programming, inputs from the front wiper and
washer control circuitry of the multi-function switch, and inputs from the front wiper motor park
switch. The coil battery terminal (86) is connected to battery current from a fuse in the Junction
Block (JB) through a fused ignition switch output (run-acc) circuit whenever the ignition switch is in
the ON or Accessory positions.
- The normally open terminal (87) is connected to battery current from a fuse in the Junction Block
(JB) through a fused ignition switch output (run-acc) circuit whenever the front wiper relay control
coil is energized by the CTM. This circuit provides fused ignition switch output (run-acc) current to
the front wiper motor low speed brush only when the front wiper relay control coil is energized.
- The normally closed terminal (87A) is connected to the output of the front wiper motor park switch
through the CTM on the front wiper park switch sense circuit. This circuit provides battery current
(wipers are not parked) or ground (wipers are parked) to the front wiper motor low speed brush
whenever the front wiper relay control coil is de-energized and the OFF position of the front wiper
control circuitry within the multi-function switch is selected.
The front wiper relay can be diagnosed using conventional diagnostic tools and methods.
REAR WIPER RELAY
The rear wiper relay is located in the Power Distribution Center (PDC) near the battery in the
engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC
cover for rear wiper relay identification and location. The rear wiper relay is a conventional
International Standards Organization (ISO) micro relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. The relay is contained within a small, rectangular, molded plastic housing. The
relay is connected to all of the required inputs and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of the relay base. The ISO designation for each
terminal is molded into the base adjacent to the terminal. The ISO terminal designations are as
follows: 30 (Common Feed) - This terminal is connected to the movable contact point of the relay.
- 85 (Coil Ground) - This terminal is connected to the ground feed side of the relay control coil.
- 86 (Coil Battery) - This terminal is connected to the battery feed side of the relay control coil.
- 87 (Normally Open) - This terminal is connected to the normally open fixed contact point of the
relay.
- 87A (Normally Closed) - This terminal is connected to the normally closed fixed contact point of
the relay.
The rear wiper relay cannot be adjusted or repaired. If the relay is damaged or faulty, it must be
replaced.
The rear wiper relay is an electromechanical switch that uses a low current input from the Central
Timer Module (CTM) to control a high current output to the rear wiper motor. The movable common
feed contact point is held against the fixed normally closed contact point by spring pressure. When
the relay coil is energized, an electromagnetic field is produced by the coil windings. This
electromagnetic field draws the movable relay
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Component Information > Locations > Page 462
contact point away from the fixed normally closed contact point, and holds it against the fixed
normally open contact point. When the relay coil is de-energized, spring pressure returns the
movable contact point back against the fixed normally closed contact point. A resistor or diode is
connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil
collapses. The rear wiper relay terminals are connected to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC). The inputs and outputs of the rear wiper relay
include:
- The common feed terminal (30) is connected to the rear wiper motor through the rear wiper motor
control circuit to the rear wiper motor. When the rear wiper relay is de-energized, the common feed
terminal is connected to ground through a take out and eyelet terminal connector of the headlamp
and dash wire harness that is secured by a nut to a ground stud located on the left front fender
inner shield in the engine compartment near the battery. When the rear wiper relay is energized,
the common feed terminal of the relay is connected to battery current from a fuse in the Power
Distribution Center (PDC) through a fused B(+) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the rear
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the rear wiper relay based upon its programming, electronic wiper and washer switch
state message inputs from the heater-air conditioner control, and a hard wired input from the rear
wiper motor park switch.
- The coil battery terminal (86) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally open terminal (87) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally closed terminal (87A) is connected to ground through a take out and eyelet terminal
connector of the headlamp and dash wire harness that is secured by a nut to a ground stud located
on the left front fender inner shield in the engine compartment near the battery.
The rear wiper relay can be diagnosed using conventional diagnostic tools and methods.

Lock Cylinder Switch: Description and Operation
DOOR CYLINDER LOCK SWITCH
A door cylinder lock switch is snapped onto the back of the key lock cylinder inside each front door.
The door cylinder lock switch is a resistor multiplexed momentary switch that is hard wired in series
between a body ground and the Central Timer Module (CTM) through the front door wire harness.
The door cylinder lock switches are driven by the key lock cylinders and contain three internal
resistors. One resistor is used for the neutral switch position, one for the Lock position, and one for
the Unlock position.
The door cylinder lock switches cannot be adjusted or repaired and, if faulty or damaged, they must
be replaced.
The door cylinder lock switches are actuated by the key lock cylinder when the key is inserted in
the lock cylinder and turned to the lock or unlock positions. The door cylinder lock switch closes a
path to ground through one of three internal resistors for the Central Timer Module (CTM) when the
front door key lock cylinder is in the Lock, Unlock, or Neutral positions. The CTM reads the switch
status through an internal pull-up, then uses this information as an input for both power lock system
and Vehicle Theft Security System (VTSS) operation.
The door cylinder lock switches and circuits can be diagnosed using conventional diagnostic tools
and methods.
LIFTGATE CYLINDER LOCK SWITCH
The liftgate cylinder lock switch is snapped onto the back of the liftgate key lock cylinder inside the
liftgate. The liftgate cylinder lock switch is a resistor multiplexed momentary switch that is hard
wired in series between a body ground and the Central Timer Module (CTM) through the liftgate
wire harness. The liftgate cylinder lock switch is driven by the key lock cylinder and contains three
internal resistors. One resistor is used for the neutral switch position, one for the Lock position and
one for the Unlock position.
The liftgate cylinder lock switch cannot be adjusted or repaired and, if faulty or damaged, it must be

Remote Switch: Description and Operation
A remote radio switch option is available on models equipped with the AM/FM/CD/cassette/3-band
graphic equalizer radio receiver and the high-line Central Timer Module (CTM). (Refer to
ELECTRONIC CONTROL MODULES/BODY CONTROL/CENTRAL TIMER MODULE DESCRIPTION).
Fig. 13 Remote Radio Switches
Two rocker-type switches are mounted in the sides of the rear (instrument panel side) steering
wheel trim cover. The switch on the left spoke is the seek switch and has seek up, seek down, and
preset station advance functions. The switch on the right spoke is the volume control switch and
has volume up, and volume down functions. The switch on the right spoke also includes a "mode"
control that allows the driver to sequentially select AM radio, FM radio, cassette player or CD
player. The two switches are retained in mounting holes located on each side of the rear steering
wheel trim cover by four latches that are integral to the switches.
The remote radio switches share a common steering wheel wire harness with the vehicle speed
control switches. The steering wheel wire harness is connected to the instrument panel wire
harness through the clockspring. (Refer to CLOCKSPRING - DESCRIPTION).
The remote radio switches are resistor multiplexed units that are hard wired to the high-line CTM
through the clockspring. The CTM monitors the status of the remote radio switches and sends the
proper switch status messages on the J1850 data bus network to the radio receiver. The electronic
circuitry within the radio is programmed to respond to these remote radio switch status messages
by adjusting the radio settings as requested.
For diagnosis of the CTM or the J1850 data bus, the use of a DRB scan tool and the proper
Diagnostic Procedures are recommended. For more information on the features and control
functions for each of the remote radio switches, see the owner's manual in the vehicle glove box.

Road Temperature Sensor: Description and Operation
AMBIENT TEMPERATURE SENSOR
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Road Temperature Sensor: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the
Diagnosis and Testing. For complete circuit diagrams, refer to Overhead Console in the Contents
of Wiring Diagrams.
Sensor Test
1. Turn the ignition switch to the OFF position. Disconnect and isolate the battery negative cable.
Disconnect the ambient temperature sensor wire

sensor as required.
4. Remove the jumper wire from the body half of the ambient temperature sensor wire harness
connector. Check for continuity between the sensor
return circuit cavity of the roof wire harness overhead console connector and a good ground. There
should be no continuity. If OK, go to Step 5. If not OK, repair the shorted sensor return circuit as
required.
5. Check for continuity between the ambient temperature sensor signal circuit cavity of the roof wire
harness overhead console connector and a good
ground. There should be no continuity. If OK, refer to Compass Mini-Trip Computer in the
Diagnosis and Testing. If not OK, repair the shorted ambient temperature sensor signal circuit as
required.

Power Door Lock Switch: Description and Operation
The power lock system can be controlled by a two way, momentary, resistor multiplexed, single
gang switch on a power lock and window switch bezel located near the forward end of the armrest
on the passenger side front door trim panel. The power lock switch on the driver side front door trim
panel is integral to the driver door module. (Refer to POWER LOCKS/DRIVER DOOR MODULE DESCRIPTION). The power lock switch is secured by integral latch tabs in a molded plastic
receptacle on the back side of the power window and lock switch bezel so that only the switch
paddle is visible where it protrudes through the bezel. The power window and lock switch bezel is
secured by small metal snap clips within an opening near the forward end of the arm rest in the
passenger side front door trim panel so that the switches can be serviced without removing the
front door trim panel. An integral connector receptacle on the back of the switch connects it to the
vehicle electrical system through a take out and connector of the right front door wire harness. The
power lock switch has a green Light-Emitting Diode (LED) located in the switch paddle to improve
switch visibility in dark ambient lighting conditions. The power lock switch cannot be adjusted or
repaired and, if faulty or damaged, the switch unit must be replaced.
The two-way, momentary, power lock switch on the passenger side front door is connected in
series between ground and the passenger door switch mux input of the Central Timer Module
(CTM). The power lock switch on the driver side front door trim panel is integral to the driver door
module. (Refer to POWER LOCKS/DRIVER DOOR MODULE - OPERATION). Each power lock
switch position Lock, Unlock, and Neutral provides a different resistance value to the CTM input
which allows the CTM to sense the switch position. Based upon the power lock switch inputs, the
CTM controls the battery and ground feed outputs to the power lock motors to lock or unlock the
door and liftgate latches. The Light-Emitting Diode (LED) in the paddle of the passenger door
power lock switch is connected to battery current through a fuse in the Junction Block (JB) on a
fused ignition switch output (run) circuit; therefore, the switch will only be illuminated when the
ignition switch is in the On position. The power lock switch can be diagnosed using conventional
diagnostic tools and methods.

Power Seat Switch: Description and Operation
DRIVER POWER SEAT SWITCH
The power seat can be adjusted in six different ways using the power seat switch. The power seat
switch for some models has an additional switch knob for adjusting the power lumbar support. The
switch is located on the lower outboard side of the seat cushion on the seat cushion side shield on
all models. Refer to the owner's manual in the vehicle glove box for more information on the power
seat switch functions and the seat adjusting procedures.
The individual switches in the power seat switch module cannot be repaired. If one switch is
damaged or faulty, the entire power seat switch module must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or recliner through its drive unit in the selected
direction until the switch is released, or until the travel limit of the adjuster is reached. When the
switch is moved in the opposite direction, the battery feed and ground path to the motor are
reversed through the switch contacts. This causes the adjuster motor to run in the opposite
direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

Seat Heater Switch: Description and Operation
DRIVER SEAT HEATER SWITCH
The heated seat switches used on vehicles with this option are both mounted in the center console.
The two switches are snapped into mounting holes in the center console. The two heated seat
switches are identical in appearance and construction, except for the location of a keyway in the
single connector receptacle and the housing on the back of each switch. The instrument panel wire
harness connectors for the heated seat switches are keyed to match the connector receptacles on
the switches so that the two heated seat switches can only be connected to the proper heated seat.
The momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal
to the heated seat module. Each switch has a center neutral position and momentary Low and High
positions so that both the driver and the front seat passenger can select a preferred seat heating
mode. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate
the selected mode (Low or High) of the seat heater for each seat and to provide diagnostic
feedback for the heated seat system. Each switch also has three other LED indicator lamps, which
provides back lighting of the switch nomenclature when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the indicator or back
lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the ON position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistor multiplexed voltage request signal
to the heated seat module to power the heated seat element of the selected seat and maintain the
requested temperature setting. If the heated seat switch is depressed to a different position (Low or
High) than the currently selected state, the heated seat module will change states to support the
new selection. If a heated seat switch is depressed a second time to the same position as the
currently selected state, the heated seat module interprets the second input as a request to turn the
seat heater OFF. The heated seat module will then turn the heated seat elements for that seat
OFF.
The indicator lamps in the heated seat switches receive battery current through a fused ignition
switch output (run) circuit when the ignition switch is in the ON position. The ground side of each
indicator lamp is controlled by a separate (high or low/driver or passenger) indicator lamp driver
circuit by the heated seat module. The heated seat module control of the switch indicator lamps
also allows the module to provide diagnostic feedback to the vehicle operator to indicate monitored
heated seat system faults by flashing the indicator lamps ON and OFF. One side of the back
lighting LED's in each heated seat switch are connected in series to ground at all times. The other
side of the LED's are connected to the ignition switch run circuit. These LED's are energized when
the ignition switch is turned to the Run position.

Trunk / Liftgate Switch: Description and Operation
LIFTGATE AJAR SWITCH
The liftgate ajar switch is integral to the latch on the liftgate. The switch closes a path to ground for
the Central Timer Module (CTM) when the liftgate is opened, and opens the ground path when the
liftgate is closed.
The liftgate ajar switch cannot be repaired and, if faulty or damaged, the liftgate latch unit must be
replaced.
The liftgate ajar switch closes a path to ground for the Central Timer Module (CTM) when the
liftgate is opened, and opens the ground path when the liftgate is closed. The liftgate ajar switch is
connected in series between ground and the CTM to provide a unique input. The CTM reads the
switch status through an internal pull-up, then sends the proper switch status messages to other
electronic modules over the Programmable Communications Interface (PCI) data bus network. The
liftgate ajar switch can be diagnosed using conventional diagnostic tools and methods.

Wheel Speed Sensor: Description and Operation Wheel Speed Sensor
OPERATION
The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor
sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic
induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary
magnetic WSS.
When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring tooth
approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic field to
cut across the sensor's windings. This, in turn causes current to flow through the WSS circuit in
one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic lines of
force collapse cutting the winding in the opposite direction. This causes the current to flow in the
opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is
generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It
then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB
continues to monitor the frequency to determine a deceleration rate that would indicate a possible
wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by:
- Magnetic field strength; the stronger the magnetic field, the stronger the signal
- Number of windings in the sensor; more windings provide a stronger signal
- Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
- Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring/tone
wheel, the stronger the signal will be
The rear WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch

The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is
spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is
monitored for proper operation.

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Cruise Control > Cruise Control Switch >
Component Information > Specifications > Page 569
Cruise Control Switch: Description and Operation
There are two separate switch pods that operate the speed control system. The
steering-wheel-mounted switches use multiplexed circuits to provide inputs to the PCM for ON,
OFF, RESUME, ACCELERATE, SET, DECEL and CANCEL modes. Refer to the owner's manual
for more information on speed control switch functions and setting procedures.
The individual switches cannot be repaired. If one switch fails, the entire switch module must be
replaced.
When speed control is selected by depressing the ON, OFF switch, the PCM allows a set speed to
be stored in its RAM for speed control. To store a set speed, depress the SET switch while the
vehicle is moving at a speed between approximately 35 and 85 mph. In order for the speed control
to engage, the brakes cannot be applied, nor can the gear selector be indicating the transmission is
in Park or Neutral.
The speed control can be disengaged manually by:
- Stepping on the brake pedal
- Depressing the OFF switch
- Depressing the CANCEL switch.
The speed control can be disengaged also by any of the following conditions:
- An indication of Park or Neutral
- The VSS signal increases at a rate of 10 mph per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
- Depressing the clutch pedal.
- Excessive engine rpm (indicates that the transmission may be in a low gear)
- The VSS signal decreases at a rate of 10 mph per second (indicates that the vehicle may have
decelerated at an extremely high rate)
- If the actual speed is not within 20 mph of the set speed
The previous disengagement conditions are programmed for added safety.
Once the speed control has been disengaged, depressing the ACCEL switch restores the vehicle
to the target speed that was stored in the PCM's RAM.
NOTE: Depressing the OFF switch will erase the set speed stored in the PCM's RAM.
If, while the speed control is engaged, the driver wishes to increase vehicle speed, the PCM is
programmed for an acceleration feature. With the ACCEL switch held closed, the vehicle
accelerates slowly to the desired speed. The new target speed is stored in the PCM's RAM when
the ACCEL switch is released. The PCM also has a "tap-up" feature in which vehicle speed
increases at a rate of approximately 2 mph for each momentary switch activation of the ACCEL
switch.
The PCM also provides a means to decelerate without disengaging speed control. To decelerate
from an existing recorded target speed, depress and hold the COAST switch until the desired
speed is reached. Then release the switch. The ON, OFF switch operates two components: the
PCM's ON, OFF input, and the battery voltage to the brake switch, which powers the speed control
servo.
Multiplexing
The PCM sends out 5 volts through a fixed resistor and monitors the voltage change between the
fixed resistor and the switches. If none of the switches are depressed, the PCM will measure 5
volts at the sensor point (open circuit). If a switch with no resistor is closed, the PCM will measure 0
volts (grounded circuit). Now, if a resistor is added to a switch, then the PCM will measure some
voltage proportional to the size of the resistor. By adding a different resistor to each switch, the
PCM will see a different voltage depending on which switch is pushed.
Another resistor has been added to the 'at rest circuit' causing the PCM to never see 5 volts. This
was done for diagnostic purposes. If the switch circuit should open (bad connection), then the PCM
will see the 5 volts and know the circuit is bad. The PCM will then set an open circuit fault.

Ambient Temperature Sensor / Switch HVAC: Description and Operation
AMBIENT TEMP SENSOR - FRONT
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the
Diagnosis and Testing. For complete circuit diagrams, refer to Overhead Console in the Contents
of Wiring Diagrams.

Low Pressure Sensor / Switch: Description and Operation
LOSS OF CHARGE SWITCH - FRONT
This vehicle is equipped with a Loss of Charge Switch. This switch is screwed onto a fitting on the
suction jumper line between the evaporator and the low side refrigerant system service port. The
switch is used to measure if refrigerant system pressure goes too low. It is not responsible for
cycling the A/C compressor clutch.
The loss of charge switch is connected in series electrically with the Heater-A/C controls between
ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the
PCM to turn the compressor clutch ON and OFF. This prevents compressor operation when the
system charge is low and prevents damage to the compressor. The switch opens with a pressure
of 7 to 13 psi and closes when the pressure rises to 15 to 25 psi.

Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Specifications > Page 601
Low Pressure Sensor / Switch: Testing and Inspection
Before performing diagnosis of the loss of charge switch, be certain that the switch is properly
installed on the suction jumper line fitting. If the switch is too loose it may not open the
Schrader-type valve in the accumulator fitting, which will prevent the switch from correctly
monitoring the refrigerant system pressure. Remember that lower ambient temperatures during
cold weather will open the switch contacts and prevent compressor operation due to the
pressure/temperature relationship of the refrigerant. Also verify that the refrigerant system has the
correct refrigerant charge.
1. Disconnect and isolate the battery negative cable. 2. Unplug the a/c loss of charge switch wire
harness connector from the switch on the refrigerant system fitting. 3. Install a jumper wire between
the two cavities of the loss of charge switch harness connector. 4. Connect a manifold gauge set to
the refrigerant system service ports. 5. Connect the battery negative cable. 6. Place the heater-A/C
mode control switch knob in any A/C position and start the engine. 7. Check for continuity between
the two terminals of the loss of charge switch. There should be continuity with a suction pressure
reading of 7 to 13
psi. If OK, test and repair the A/C switch sense circuit as required. If not OK, replace the faulty
switch.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Fuel Gauge Sender: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To
test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump
module. Refer to Fuel Pump Module Removal/installation for procedures. Measure the resistance
across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6%.
With float in down position, resistance should be 270 ohms ± 6%.

Brake Light Switch: Description and Operation
The plunger type brake lamp switch is mounted on a bracket attached to the brake pedal support.
CAUTION: The switch can only be adjusted during initial installation. If the switch is not adjusted
properly a new switch must be installed.
The primary function of the switch is to turn ON the brake lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses
the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes
applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to
anticipate the need for an RWAL stop.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Door Switch: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each door. The switches close a path to
ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Hazard Warning Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Hazard Warning Switch
> Component Information > Diagrams > Page 690
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Horn Switch: Description and Operation
Fig. 3 Driver Side Airbag Module Trim Cover And Horn Switch
A center-blow, normally open, resistive membrane-type horn switch is secured with heat stakes to
the back side of the driver side airbag module trim cover in the center of the steering wheel . The
switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two
membranes are secured to each other around the perimeter. Inside the switch, the centers of the
facing surfaces of these membranes each has a grid made with an electrically conductive material
applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all
times. The grid of the other membrane is connected to the horn relay control circuit.
The steering wheel and steering column must be properly grounded in order for the horn switch to
function properly. The horn switch is only serviced as a part of the driver side airbag module trim
cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side
airbag module trim cover and horn switch must be replaced as a unit.
When the center area of the driver side airbag trim cover is depressed, the electrically conductive
grids on the facing surfaces of the horn switch membranes contact each other, closing the switch
circuit. The completed horn switch circuit provides a ground for the control coil side of the horn
relay, which activates the relay. When the horn switch is released, the resistive tension of the
convex membrane separates the two electrically conductive grids and opens the switch circuit.

Turn Signal Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Lighting and Horns > Turn Signal Switch >
Component Information > Diagrams > Page 709
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Dodge Workshop Manuals > Sensors and Switches > Sensors and Switches - Powertrain Management > Sensors and

Fuel Level Sensor: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Intake Air Temperature (IAT) Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold with the
sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-ON,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Manifold Absolute Pressure (MAP) Sensor: Description and Operation
The MAP sensor is located on the front of the intake manifold. An O-ring seals the sensor to the
intake manifold.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-ON, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-ON (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor.
As the altitude increases, the air becomes thinner (less oxygen). If a vehicle is started and driven to
a very different altitude than where it was at key-ON, the barometric pressure needs to be updated.
Any time the PCM sees Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS)
angle and RPM, it will update barometric pressure in the MAP memory cell. With periodic updates,
the PCM can make its calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an object. At sea level on a standard
day, no storm, barometric pressure is approximately 29.92 in Hg. For every 100 feet of altitude,
barometric pressure drops 0.10 in. Hg. If a storm goes through it can change barometric pressure
from what should be present for that altitude. You should know what the average pressure and
corresponding barometric pressure is for your area.

Oxygen Sensor: Description and Operation
The Oxygen Sensors (O2S) are attached to, and protrude into the vehicle exhaust system.
Depending on the emission package, the vehicle may use a total of either 2 or 4 sensors.
NAA Emissions Package: Two sensors are used: upstream (referred to as 1/1) and downstream
(referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before
the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic
convertor.
NAS or NAE Emissions Package: On this emissions package, 4 sensors are used: 2 upstream
(referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission
package, the right upstream sensor (2/1) is located in the right exhaust downpipe just before the
mini-catalytic convertor. The left upstream sensor (1/1) is located in the left exhaust downpipe just
before the mini-catalytic convertor. The right downstream sensor (2/2) is located in the right
exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor.
The left downstream sensor (1/2) is located in the left exhaust downpipe just after the mini-catalytic
convertor, and before the main catalytic convertor.
An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely
proportional to the amount of oxygen in the exhaust. In other words, if the oxygen content is low,
the voltage output is high; if the oxygen content is high the output voltage is low. The PCM uses
this information to adjust injector pulse-width to achieve the 14.7-to-1 air/fuel ratio necessary for
proper engine operation and to control emissions.
The O2 sensor must have a source of oxygen from outside of the exhaust stream for comparison.
Current O2 sensors receive their fresh oxygen (outside air) supply through the wire harness. This is
why it is important to never solder an O2 sensor connector, or pack the connector with grease.
Four wires (circuits) are used on each O2 sensor: a 12-volt feed circuit for the sensor heating
element; a ground circuit for the heater element; a low-noise sensor return circuit to the PCM, and
an input circuit from the sensor back to the PCM to detect sensor operation.
Oxygen Sensor Heater Relay: If the vehicle is equipped with 4 oxygen sensors, a separate oxygen
sensor relay is used to supply voltage to the sensor heating elements. This particular relay is used
only for the 1/2 and 2/2 downstream sensors. Voltage for the other 2 sensor heating elements is
supplied directly from the ASD relay.
To avoid the large simultaneous current surge needed to operate all 4 sensors, power is delayed to
the 2 downstream heater elements by the PCM for approximately 2 seconds.
Oxygen Sensor Heater Elements: The O2 sensor uses a Positive Thermal Co-efficient (PTC)
heater element. As temperature increases, resistance increases. At ambient temperatures around
70 °F, the resistance of the heating element is approximately 13.5 ohms on the this engine. As the
sensor's temperature increases, resistance in the heater element increases. This allows the heater
to maintain the optimum operating temperature of approximately 930 ° - 1100 °F (500 ° - 600 °C).
Although the sensors operate the same, there are physical differences, due to the environment that
they operate in, that keep them from being interchangeable.
Maintaining correct sensor temperature at all times allows the system to enter into closed loop
operation sooner. Also, it allows the system to remain in closed loop operation during periods of
extended idle.
In Closed Loop operation, the PCM monitors certain O2 sensor input(s) along with other inputs,
and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the
O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values
and inputs from other sensors.
Upstream Sensor - Engine Equipped With 2 Sensors: The upstream sensor (1/1) provides an input
voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses
this information to fine tune fuel delivery to maintain the correct oxygen content at the downstream
oxygen sensor. The PCM will change the air/fuel ratio until the upstream sensor inputs a voltage
that the PCM has determined will make the downstream sensor output (oxygen content) correct.
The upstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Downstream Sensor - Engine Equipped With 2 Sensors: The downstream oxygen sensor (1/2) is
also used to determine the correct air-fuel ratio. As the oxygen content changes at the downstream
sensor, the PCM calculates how much air-fuel ratio change is required. The PCM then looks at the
upstream oxygen sensor voltage and changes fuel delivery until the upstream sensor voltage
changes enough to correct the downstream sensor voltage (oxygen content).
The downstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Upstream Sensors - Engine Equipped With 4 Sensors: Two upstream sensors are used (1/1 and
2/1). The 1/1 sensor is the first sensor to receive exhaust gases from the # 1 cylinder. They provide
an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The
PCM uses this information to fine tune fuel delivery to maintain the correct oxygen content at the
downstream oxygen sensors. The PCM will change the air/fuel ratio until the upstream sensors
input a voltage that the PCM has determined will make the downstream sensors output (oxygen
content) correct.
The upstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.

Lamp (MIL) will be illuminated and a Diagnostic Trouble Code (DTC) will be set. Refer to Monitored
Systems in Emission Control Systems for additional information.

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Seat Belt Buckle Switch: Description and Operation
LUMBAR CONTROL SWITCH
The 8-way power seat option includes an electrically operated lumbar support mechanism. A single
two-way momentary power lumbar switch is integral with the power seat switches. The power
lumbar switch is secured to the back of the seat cushion side shield with screws, and the switch
paddle protrudes through a hole to the outside of the shield. The switch paddle is located in a
shallow depression molded into the outer surface of the seat cushion side shield that helps to
shroud it from unintentional actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or repaired and, if faulty or damaged, the seat
switch assembly must be replaced.
When the power lumbar switch paddle is actuated, a battery feed and a ground path are applied
through the switch contacts to the power lumbar adjuster motor. The motor operates to move the
lumbar adjuster through its drive unit in the selected direction until the switch is released, or until
the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the
battery feed and ground path to the motor are reversed through the switch contacts. This causes
the motor to run in the opposite direction.
The power lumbar switch should not be held applied in either direction after the adjuster has
reached its travel limit. The power lumbar adjuster motor contains a self-resetting circuit breaker to
protect it from overload. However, consecutive or frequent resetting of the circuit breaker must not
be allowed to continue, or the motor may be damaged.
SEAT BELT SWITCH
The seat belt switch is a small, normally open, single pole, single throw, plunger actuated,
momentary switch. Only one seat belt switch is installed in the vehicle, and it is integral to the driver
seat belt retractor assembly. The seat belt switch is connected to the vehicle electrical system
through a short pigtail wire to a dedicated take out and connector of the body wire harness.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver seat
belt and retractor unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the Electro-Mechanical Instrument Cluster (EMIC). The seat belt switch plunger is actuated by the
seat belt webbing wound onto the seat belt retractor spool. When the seat belt tip-half webbing is
pulled out of the retractor far enough to engage the seat belt buckle-half, the switch plunger is
extended and closes the seat belt switch sense circuit to ground; and, when the seat belt tip-half
webbing is wound onto the retractor the switch plunger is depressed, opening the ground path. The
EMIC monitors the seat belt switch status, then controls the seatbelt indicator and sends electronic
chime request messages over the Programmable Communications Interface (PCI) data bus to the
Central Timer Module (CTM) based upon that input.
The seat belt switch receives ground through its pigtail wire connection to the body wire harness
from another take out of the body wire harness. An eyelet terminal connector on that ground take
out is secured under a ground screw to the left lower B-pillar. The seat belt switch is connected in
series between ground and the seat belt switch sense input of the EMIC.

There should be continuity. If OK, go to Step 2. If not OK, repair the open ground circuit to ground
(G307) as required.
2. Check for continuity between the two cavities in the seat belt switch pigtail wire connector. There
should be no continuity with the seat belt
webbing retracted, and continuity with the seat belt webbing pulled out of the retractor far enough
to engage the seat belt buckle. If OK, go to Step 3 .If not OK, replace the faulty driver side front
seat belt and retractor unit.
3. Remove the instrument cluster from the instrument panel. Check for continuity between the seat
belt switch sense circuit cavity of the body wire
harness connector for the seat belt switch and a good ground. There should be no continuity. If OK,
go to Step 4. If not OK, repair the shorted seat belt switch sense circuit between the seat belt
switch and the instrument cluster as required.
4. Check for continuity between the seat belt switch sense circuit cavities of the instrument panel
wire harness connector (Connector C2) for the
instrument cluster and the body wire harness connector for the seat belt switch. There should be
continuity. If OK, proceed to the diagnosis for the instrument cluster. (Refer to INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING). If not OK, repair the open seat belt switch sense circuit
between the seat belt switch and the instrument cluster as required.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

Rear Window Defogger Switch: Description and Operation
The rear window defogger switch is integral to the heater-A/C control assembly, which includes the
rear wiper and washer switches.
The rear window switch also contains the rear window defogger logic and timer circuitry, an amber
defogger indicator lamp, the rear window defogger relay, and two switch illumination lamps. The
indicator and illumination lamps in the switch pod use incandescent bulbs, which can be serviced.
The momentary-type rear window defogger switch provides a hard wired ground signal to the rear
window defogger logic and timer circuitry, each time it is depressed.
The rear window defogger timer and logic circuitry responds by energizing or de-energizing the
rear window defogger relay and the amber defogger indicator lamp, which lights to indicate when
the defogger system is turned ON. Energizing the rear window defogger relay provides electrical
current to the rear window defogger grid.
The rear window switch cannot be repaired. If any function of the switch except lighting is faulty or
damaged, the entire heater-A/C control assembly must be replaced.

Power Window Switch: Description and Operation
The power windows are controlled by two-way switches integral to the power window and lock
switch and bezel unit on the trim panel of each front door. A second power window switch in the
driver side switch and bezel unit allows the driver to control the passenger windows.
The power window switch for the driver side front door window has an Auto label on it. This switch
has a second detent position beyond the normal Down position that provides an automatic
one-touch window down feature. This feature is controlled by an electronic circuit and a relay that
are integral to the Driver Door Module.
The power window switches control the battery and ground feeds to the power window motors. All
of the passenger door power window switches receive their battery and ground feeds through the
circuitry of the Driver Door Module. When the power window lockout switch is in the Lock position,
the battery feed for the individual passenger door power window switches is interrupted.
A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition
switch is in the ON position. However, the LEDs for the passenger power window switches are
extinguished whenever the driver selects the Lock position with the power window lockout switch.

Washer Fluid Level Switch: Description and Operation
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the
outboard side of the washer reservoir forward of the two washer pump/motors, in the right front
corner of the engine compartment. Only the molded plastic switch mounting flange and connector
receptacle are visible when the switch is installed in the reservoir. A short nipple formation extends
from the inner surface of the switch mounting flange, and a barb on the nipple near the switch
mounting flange is press-fit into a rubber grommet seal installed in the mounting hole of the
reservoir. A small plastic float pivots on the end of a bracket that extends from the switch nipple
formation. Within the float is a small magnet, which actuates the reed switch. The washer fluid level
switch cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced.
The washer fluid level switch uses a pivoting, oblong float to monitor the level of the washer fluid in
the washer reservoir. The float contains a small magnet. When the float pivots, the changing
proximity of its magnetic field will cause the contacts of the small, stationary reed switch to open or
close. When the fluid level in the washer reservoir is at or above the float level, the float moves to a
vertical position and the switch contacts open. When the fluid level in the washer reservoir falls
below the pivoting float, the float moves to a horizontal position and the switch contacts close. The
switch contacts are connected in series between ground and the washer fluid switch sense input of
the instrument cluster. The switch is connected to the vehicle electrical system through a dedicated
take out and connector of the headlamp and dash wire harness. The switch receives ground
through another take out of the headlamp and dash wire harness with a single eyelet terminal
connector that is secured under a nut to a ground stud located on the right front fender inner shield
in the engine compartment. The washer fluid level switch can be diagnosed using conventional
diagnostic tools and methods. (Refer to WASHER FLUID INDICATOR - DIAGNOSIS AND
TESTING).

Alignment: Description and Operation
DESCRIPTION
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
CAUTION: Never attempt to modify suspension or steering components by heating or bending.
NOTE: Periodic lubrication of the front suspension/steering system components may be required.
Rubber bushings must never be lubricated.
OPERATION
- CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive
caster. Positive caster promotes directional stability. This angle enables the front wheels to return
to a straight ahead position after turns.
- CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire.
- TOE is the difference between the leading inside edges and trailing inside edges of the front tires.
wheel position out of specification cause's unstable steering, uneven tire wear and steering wheel
off center. The wheel toe position is the final front wheel alignment adjustment.
- THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect
thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable,
damaged component(s) must be replaced to correct the thrust angle.

completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for
wear. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball
studs, linkage pivot points and steering gear for looseness, roughness or binding. 5. Inspect
suspension components for wear and noise. 6. On 4x4 vehicles check suspension height. 7. Road
test the vehicle.

Alignment: Service and Repair Wheel Alignment
STANDARD PROCEDURE - HEIGHT MEASUREMENT
The vehicle suspension height should be measured and adjusted if necessary before performing
wheel alignment procedure. Also when front suspension components have been replaced. This
measure must be performed with the vehicle supporting it's own weight and taken on both sides of
the vehicle. 1. Jounce the front of the vehicle.
2. Measure and record the distance between the ground and the center of the lower suspension
arm rear mounting bolt head. 3. Measure and record the distance between the ground and the
center of the front wheel. 4. Subtract the first measurement from the second measurement. The
difference between the two measurement should be 73 mm (2.9 inches) + 3
mm (0.12 inches).
STANDARD PROCEDURE- HEIGHT ADJUSTMENT
The vehicle suspension height should be measured and adjusted if necessary before performing
wheel alignment procedure. Also when front suspension components have been replaced. This
measure must be performed with the vehicle supporting it's own weight and taken on both sides of
the vehicle. To adjust the vehicle height turn the torsion bar adjustment bolt CLOCKWISE to raise
the vehicle and COUNTER CLOCKWISE to lower the vehicle.
CAUTION: ALWAYS raise the vehicle to the correct suspension height, NEVER lower the vehicle
to obtain the correct suspension height. If the vehicle suspension height is too high, lower the
vehicle below the height specification. Then raise the vehicle to the correct suspension height
specification. This will insure the vehicle maintains the proper suspension height.
NOTE: If a height adjustment has been made, perform height measurement again on both sides of
the vehicle.
STANDARD PROCEDURE - CAMBER AND CASTER ADJUSTMENT
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Alignment > System Information > Service and Repair > Pre-Alignment
Inspection > Page 966
Camber and caster angle adjustments involve changing the position of the upper suspension arm
pivot bar.
NOTE: On 4x2 vehicles use Alignment Tool 8393 for alignment. The tool attaches to the pivot bar
on the upper control arm.
STANDARD PROCEDURE- CASTER
Moving the rear position of the pivot bar in or out, will change the caster angle significantly and
camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of
the pivot bar in or out. Then move the front of the pivot bar slightly in the opposite direction. To
increase positive caster angle, move the rear position of the pivot bar inward (toward the engine).
Move the front of pivot bar outward (away from the engine) slightly until the original camber angle is
obtained.
STANDARD PROCEDURE - CAMBER
Move the front of the pivot bar in or out. This will change the camber angle significantly and caster
angle slightly. After adjustment is made tighten the pivot bar nuts to proper torque specification.
STANDARD PROCEDURE - TOE ADJUSTMENT
The wheel toe position adjustment is the final adjustment. 1. Start the engine and turn wheels both
ways before straightening the wheels. Secure the steering wheel with the front wheels in the
straight-ahead
position.
2. Loosen the tie rod jam nuts.
NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This
will ensure the steering wheel will be centered when the wheels are positioned straight-ahead.
3. Adjust the wheel toe position by turning the tie rod as necessary. 4. Tighten the tie rod jam nut to
75 Nm (55 ft. lbs.).

Spark Plug: Description and Operation
This engine are equipped with "fired in suppressor seal" type spark plugs using a copper core
ground electrode.
Because of the use of an aluminum cylinder head on this engine, spark plug torque is very critical.
To prevent possible pre-ignition and/or mechanical engine damage, the correct type/heat
range/number spark plug must be used.
Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken
porcelain insulators. Keep plugs arranged in the order in which they were removed from the
engine. A single plug displaying an abnormal condition indicates that a problem exists in the
corresponding cylinder. Replace spark plugs at the intervals recommended in Lubrication and
Maintenance.
Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or
oil fouled. Also refer to Spark Plug Conditions.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator and will cause plug misfire.

Spark Plug: Testing and Inspection
SPARK PLUG CONDITIONS
Fig. 20 Normal Operation And Cold (Carbon) Fouling
Normal Operating The few deposits present on the spark plug will probably be light tan or slightly
gray in color. This is evident with most grades of commercial gasoline. There will not be evidence
of electrode burning. On this engine gap growth will not average more than approximately 0.0015
in per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be
cleaned, have the electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a Manganese Additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits.
Cold Fouling/carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits
that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may
be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set
of spark plugs may be caused by a clogged air cleaner element or repeated short operating times
(short trips).
Wet Fouling Or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In
older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause
wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal
oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the
fouled plugs.

Information > Specifications > Page 1006
Fig. 21 Oil Or Ash Encrusted
Oil Or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine
condition for the cause of oil entry into that particular combustion chamber.
Fig. 22 Electrode Gap Bridging
Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion
chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving.
When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge
the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap
bridging can be cleaned using standard procedures.

Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component
Information > Specifications > Page 1007
Fig. 23 Scavenger Deposits
Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to
be harmful, but this is a normal condition caused by chemical additives in certain fuses. These
additives are designed to change the chemical nature of deposits and decrease spark plug misfire
tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the
deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in
condition and can be cleaned using standard procedures.
Fig. 24 Chipped Electrode Insulator
Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center
electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation
can also separate the insulator from the center electrode. Spark plugs with this condition must be
replaced.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Tune-up and Engine Performance Checks > Spark Plug > Component
Information > Specifications > Page 1008
Fig. 25 Preignition Damage
Preignition Damage Preignition damage is usually caused by excessive combustion chamber
temperature. The center electrode dissolves first and the ground electrode dissolves somewhat
latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat
range rating for the engine. Determine if ignition timing is over advanced or if other operating
conditions are causing engine overheating. (The heat range rating refers to the operating
temperature of a particular type spark plug. Spark plugs are designed to operate within specific
temperature ranges. This depends upon the thickness and length of the center electrodes porcelain
insulator.)
Fig. 26 Spark Plug Overheating
Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that
also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch
per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be
used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause
spark plug overheating.

REMOVAL
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
In this engine: Each individual spark plug is located under each ignition coil. Each individual ignition
coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
1. In this engine: Prior to removing spark plug, spray compressed air around base of ignition coil at
cylinder head. This will help prevent foreign
material from entering combustion chamber.
2. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. If
equipped with this engine, also check condition of
coil O-ring and replace as necessary.
3. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
The plugs may be cleaned using commercially available spark plug cleaning equipment. After
cleaning, file center electrode flat with a small point file or jewelers file before adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean spark plugs. Metallic deposits will
remain on spark plug insulator and will cause plug misfire.
INSTALLATION
CAUTION: This engine is equipped with copper core ground electrode spark plugs. They must be
replaced with the same type/number spark plug as the original. If another spark plug is substituted,
pre-ignition will result.
Special care should be taken when installing spark plugs into the cylinder head spark plug wells.
Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. In this engine:
Tighten spark plugs to 27 Nm (20 ft. lbs.) torque. 3. In this engine: Before installing coil(s), check
condition of coil O-ring and replace as necessary. To aid in coil installation, apply silicone to coil
O-ring.
4. In this engine: Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

VISUAL DIAGNOSIS
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib (Fig. 9), are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced (Fig. 9). Also replace the belt if it has excessive wear, frayed cords or
severe glazing. Refer to ACCESSORY DRIVE BELT DIAGNOSIS CHART for further belt
diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

NOTE:
This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales
code DG4 or DGQ respectively).
DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

NOTE:
This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales
code DG4 or DGQ respectively).
DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

NOTE:
A replacement 04799662 cooler return filter may come packaged with a separate threaded adapter
stud. The threaded adapter stud is used to attach the cooler return filter to the transmission.
Inspect the stud and note end without threads. Install the stud end without the threads into the
cooler return filter and tighten the stud-to-filter connection to 18.6 Nm (165 in. lbs.). Once the
threaded adapter stud has been installed to the cooler return filter, install the assembled cooler
return filter to the transmission and tighten the filter to 14.1 Nm (125 in. lbs.)

Fluid Level Check
Fluid Filter - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells
burned, and is contaminated with metal or friction material particles, a complete transmission
recondition is needed. Be sure to examine the fluid on the dipstick closely. If there is any doubt
about its condition, drain out a sample for a double check.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F.), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up DRB@ scan tool and select transmission. 6. Select sensors. 7.
Read the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.

Hose/Line HVAC: Service Precautions
Kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire system. High
pressures are produced in the system when it is operating. Extreme care must be exercised to
make sure that all refrigerant system connections are pressure tight.
A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times
the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines
should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a
good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure
they are in good condition and properly routed.
There are two types of refrigerant fittings:
- All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings
that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result
in a leak.
- Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not
reusable and new gaskets do not require lubrication before installing.
Using the proper tools when making a refrigerant plumbing connection is very important. Improper
tools or improper use of the tools can damage the refrigerant fittings.
The refrigerant must be recovered completely from the system before opening any fitting or
connection. Open the fittings with caution, even after the refrigerant has been recovered. If any
pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the
system again.
Do not discharge refrigerant into the atmosphere. Use an R-134a refrigerant recovery/recycling
device that meets SAE Standard J2210.
The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a
refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability.
Operational troubles or serious damage can occur if foreign material is present in the refrigerant
system.
When it is necessary to open the refrigerant system, have everything needed to service the system
ready. The refrigerant system should not be left open to the atmosphere any longer than
necessary. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of
dirt and moisture. All lines and components in parts stock should be capped or sealed until they are
to be installed.
All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses
should be kept clean and dry. All tools and equipment must be designed for R-134a refrigerant.

Hose/Line HVAC: Description and Operation
REFRIGERANT LINES
The refrigerant lines and hoses are used to carry the refrigerant between the various air
conditioning system components. A barrier hose design with a nylon tube, which is sandwiched
between rubber layers, is used for the R-134a air conditioning system on this vehicle. This nylon
tube helps to further contain the R-134a refrigerant, which has a smaller molecular structure than
R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminum or steel,
and commonly use braze-less fittings.
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air
conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good
rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the
diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at
least 80 millimeters (3 inches) from the exhaust manifold.
High pressures are produced in the refrigerant system when the air conditioning compressor is
operating. Extreme care must be exercised to make sure that each of the refrigerant system
connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose
refrigerant lines at least once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses are coupled with other components of the HVAC system with
peanut-block style fittings. A stat-O seal type flat steel gasket with a captured compressible O-ring,
is used to mate plumbing lines with A/C components to ensure the integrity of the refrigerant
system.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

DIAGNOSIS AND TESTING - BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteriorated rubber parts.
Swollen rubber parts indicate the presence of petroleum in the brake fluid.
To test for contamination, put a small amount of drained brake fluid in clear glass jar. If fluid
separates into layers, there is mineral oil or other fluid contamination of the brake fluid.
If brake fluid is contaminated, drain and thoroughly flush system. Replace master cylinder,
proportioning valve, caliper seals, wheel cylinder seals, Antilock Brakes hydraulic unit and all
hydraulic fluid hoses.

W5J400 or NAG1 transmission (sales code DGJ).
DISCUSSION:
ATF+4(R) - (Type 9602) is being used as factory fill for Chrysler Group automatic transmissions.
ATF+4(R) is recommended for all vehicles equipped with Chrysler Group automatic transmissions
EXCEPT FOR THOSE LISTED IN THE NOTE ABOVE.
NOTE:
ATF+4(R) must always be used in vehicles that were originally filled with ATF+4(R). DO NOT USE
ANY OTHER FLUID.
NOTE:
ATF+4(R) is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4(R) can be
used to top off vehicles that used ATF+3, ATF+2, or ATF+.
NOTE:
If ATF+4® is used to service models originally filled with ATF+3, ATF+2, and ATF+ the fluid
maintenance schedules listed for that model does not change. The service interval currently in
effect for a given model should continue to be followed. Refer to the Service or Owners manual for
maintenance schedule directions.
In general terms, If ATF+, ATF+2 or ATF+3 was the recommended fluid, it is now recommended to
use ATF+4®
BENEFITS
^ Better anti-wear properties
^ Improved rust/corrosion prevention
^ Controls oxidation
^ Eliminates deposits
^ Controls friction
^ Retains anti-foaming properties
^ Superior properties for low temperature operation
FLUID COLOR
Mopar ATF+4(R) has exceptional durability. However, the red dye used in ATF+4(R) is not
permanent; as the fluid ages it may become darker or appear brown in color. ATF+4(R) also has a
unique odor that may change with age. With ATF+4(R) fluid, color and odor are no longer
indicators of fluid condition and do not necessarily support a fluid change.

Effects of Incorrect Fluid Level
Fluid - A/T: Testing and Inspection Effects of Incorrect Fluid Level
EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal. If the transmission is overfilled, the gears
chum the fluid into foam. This aerates the fluid and causing the same conditions occurring with a
low level. In either case, air bubbles cause fluid overheating, oxidation and varnish buildup which
interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in
fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a
leak if inspection is not careful.

Fluid - A/T: Testing and Inspection Causes of Burnt Fluid
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes. 1. Internal clutch
slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal
failure. 2. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is
usually the result of a faulty or improperly installed
drainback valve, a damaged main cooler, or severe restrictions in the coolers and lines caused by
debris or kinked lines.
3. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer
towing or similar high load operation will overheat
the transmission fluid if the vehicle is improperly equipped. Such vehicles should have an auxiliary
transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination
needed to handle heavy loads.

Fluid - A/T: Testing and Inspection Fluid Contamination
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of:
- adding incorrect fluid
- failure to clean dipstick and fill tube when checking level
- engine coolant entering the fluid
- internal failure that generates debris
- overheat that generates sludge (fluid breakdown)
- failure to reverse flush cooler and lines after repair
- failure to replace contaminated converter after repair
The use of non-recommended fluids can result in transmission failure. The usual results are erratic
shifts, slippage, abnormal wear and eventual failure due to fluid breakdown and sludge formation.
Avoid this condition by using recommended fluids only.
The dipstick cap and fill tube should be wiped clean before checking fluid level. Dirt, grease and
other foreign material on the cap and tube could fall into the tube if not removed beforehand. Take
the time to wipe the cap and tube clean before withdrawing the dipstick.
Engine coolant in the transmission fluid is generally caused by a cooler malfunction. The only
remedy is to replace the radiator as the cooler in the radiator is not a serviceable part.
If coolant has circulated through the transmission, an overhaul is necessary.
The transmission cooler and lines should be reverse flushed whenever a malfunction generates
sludge and/or debris. The torque converter should also be replaced at the same time.
Failure to flush the cooler and lines will result in recontamination. Flushing applies to auxiliary
coolers as well. The torque converter should also be replaced whenever a failure generates sludge
and debris. This is necessary because normal converter flushing procedures will not remove all
contaminants.

Level Check
Fluid - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells
burned, and is contaminated with metal or friction material particles, a complete transmission
recondition is needed. Be sure to examine the fluid on the dipstick closely. If there is any doubt
about its condition, drain out a sample for a double check.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F.), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up DRB@ scan tool and select transmission. 6. Select sensors. 7.
Read the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.

Transmission Fluid Temperature Chart
INSPECTION Inspect bottom of pan and magnet for excessive amounts of metal. A light coating of
clutch material on the bottom of the pan does not indicate a problem unless accompanied by a
slipping condition or shift lag. If fluid and pan are contaminated with excessive amounts of debris.
CLEANING 1. Using a suitable solvent, clean pan and magnet. 2. Using a suitable gasket scraper,
clean original sealing material from surface of transmission case and the transmission pan.
INSTALLATION 1. Install a new oil filter seal into the bottom of the oil pump.
NOTE: Do not attempt to install the seal onto the oil filter first and then into the oil pump. An
unsatisfactory seal between the oil pump and filter will result, allowing air to be drawn into the
pump.
2. Place replacement filter in position on valve body and into the oil pump. 3. Install screw to hold
filter to valve body (Fig. 54). Tighten screw to 4.5 Nm (40 inch lbs.) torque. 4. Install new cooler
return filter onto the transmission, if necessary. Torque the filter to 14.12 Nm (125 inch lbs.). 5.
Place bead of Mopar(R) RTV sealant onto the transmission case sealing surface. 6. Place pan in
position on transmission. 7. Install bolts to hold pan to transmission. Tighten bolts to 11.8 Nm (105
inch lbs.) torque. 8. Lower vehicle and fill transmission with Mopar(R) ATF +4, type 9602 fluid.

NOTE:
THIS BULLETIN APPLIES TO ALL DAIMLERCHRYSLER MODELS/ENGINES BUILT BEFORE
AND AFTER THE 2001 MODEL YEAR.
DISCUSSION Engine oil additives/supplements (EOS) should not be used to enhance engine oil
performance. Engine oil additives/supplements should not be used to extend engine oil change
intervals. No additive is known to be safe for engine durability and can degrade emission
components. Additives can contain undesirable materials that harm the long term durability of
engines by:
^ Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard
Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10%
Phosphorus to protect the vehicles emissions performance. Addition of engine oil
additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder
efforts to guarantee our emissions performance to 80,000 miles and new requirements of 150,000
miles.
^ Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements
of the specified viscosity grade.
^ Creating potential for an undesirable additive compatibility interaction in the engine crankcase.
Generally it is not desirable to mix additive packages from different suppliers in the crankcase;
there have been reports of low temperature engine failures caused by additive package
incompatibility with such mixtures.

SAFETY PRECAUTIONS
WARNING: Prolonged and repeated contact with used engine oil may cause skin cancer.
Avoid prolonged and repeated contact with oils, particularly used engine oils.
- Wear protective clothing, including impervious gloves where practicable.
- Do not put oily rags in pockets.
- Avoid contaminating clothes, particularly underpants, with oil.
- Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be
cleaned regularly.
- First Aid treatment should be obtained immediately for open cuts and wounds.
- Use barrier creams, applying them before each work period, to help the removal of oil from the
skin.
- Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help).
Preparations containing lanolin replace the natural skin oils which have been removed.
- Do not use gasoline, kerosine, diesel fuel, gas oil, thinner or solvents for cleaning skin.
- If skin disorders develop, obtain medical advice without delay.
- Where practicable, degrease components prior to handling.
- Where there is a risk of eye contact, eye protection should be worn, for example, chemical
goggles or face shields; in addition an eye wash facility should be provided.

Engine Oil: Service and Repair
STANDARD PROCEDURE - ENGINE OIL SERVICE
WARNING: NEW OR USED ENGINE OIL CAN BE IRRITATING TO THE SKIN. AVOID
PROLONGED OR REPEATED SKIN CONTACT WITH ENGINE OIL. CONTAMINANTS IN USED
ENGINE OIL, CAUSED BY INTERNAL COMBUSTION, CAN BE HAZARDOUS TO YOUR
HEALTH. THOROUGHLY WASH EXPOSED SKIN WITH SOAP AND WATER. DO NOT WASH
SKIN WITH GASOLINE, DIESEL FUEL, THINNER, OR SOLVENTS, HEALTH PROBLEMS CAN
RESULT. DO NOT POLLUTE, DISPOSE OF USED ENGINE OIL PROPERLY.
ENGINE OIL SPECIFICATION
CAUTION: Do not use non-detergent or straight mineral oil when adding or changing crankcase
lubricant. Engine failure can result.
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Service Grade Certified. MOPAR provides engine oils that conform to
this service grade.
SAE VISCOSITY
An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with
multiple viscosities such as 5W-30 or 1OW-30 in the 4.7L engines. These are specified with a dual
SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine
oil that is best suited to your particular temperature range and variation (Fig. 97).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY
CONSERVING is located on the label of an engine oil container.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have been adopted to aid in the proper selection of
engine oil. The identifying notations are located on the label of engine oil plastic bottles and the top
of engine oil cans (Fig. 98).
OIL LEVEL INDICATOR (DIPSTICK)
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Fluids > Engine Oil > Component Information > Specifications > Page 1145
The engine oil level indicator is located at the right rear of the engine on the 4.7L engines. (Fig. 99).
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles). Unless the engine has
exhibited loss of oil pressure, run the engine for about five minutes before checking oil level.
Checking engine oil level on a cold engine is not accurate. To ensure proper lubrication of an
engine, the engine oil must be maintained at an acceptable level. The acceptable levels are
indicated between the ADD and SAFE marks on the engine oil dipstick. 1. Position vehicle on level
surface. 2. With engine OFF, allow approximately ten minutes for oil to settle to bottom of
crankcase, remove engine oil dipstick. 3. Wipe dipstick clean. 4. Install dipstick and verify it is
seated in the tube. 5. Remove dipstick, with handle held above the tip, take oil level reading. 6. Add
oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules. Run engine
until achieving normal operating temperature. 1. Position the vehicle on a level surface and turn
engine off. 2. Hoist and support vehicle on safety stands. 3. Remove oil fill cap. 4. Place a suitable
drain pan under crankcase drain. 5. Remove drain plug from crankcase and allow oil to drain into
pan. Inspect drain plug threads for stretching or other damage. Replace drain plug if
damaged.
6. Install drain plug in crankcase. 7. Lower vehicle and fill crankcase with specified type and
amount of engine oil. 8. Install oil fill cap. 9. Start engine and inspect for leaks.
10. Stop engine and inspect oil level.
USED ENGINE OIL DISPOSAL
Care should be exercised when disposing used engine oil after it has been drained from a vehicle
engine. Refer to the WARNING.

DISCUSSION:
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4
(MS9602) and it provides superior performance at both low and high temperatures. WJ/WG and ZH
vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved
service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and
MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is
no longer an indication of fluid condition.
The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number
for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA.
MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On
some past models, MS9602 should be used as the replacement fluid. On these models, if a power
steering system is being serviced that results in a large fluid loss, such as a pump, hose or
gear/rack replacement, the complete system should be drained and filled with MS9602.

Refrigerant: Service Precautions
R-134a - R-12
Because R-134a refrigerant is a hydrofluorocarbon (HFC) which contains hydrogen atoms in place
of chlorine atoms, it will not cause damage to the ozone layer.
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone layer, Chrysler
Corporation recommends an R-134a refrigerant recycling device.
The Clean Air Act Amendment of 1990 requires that Freon be recovered when accessing the air
conditioning circuit and that technicians hold a refrigerant recovery and handling certification.
The Ozone Layer A thin layer of ozone molecules, located 10 to 30 miles above the earth, form a
protective cover by absorbing a portion of the ultraviolet (UV) radiation emitted from the Sun.
Ozone Depletion Scientific research performed over the past 15 years links the release of
chlorofluorocarbons (CFC)s, also know by the trade name Freon) into the atmosphere to ozone
depletion. When CFCs are released into the atmosphere, they eventually reach the ozone layer
located in the stratosphere where they react with and destroy ozone molecules.
Harmful Effects Ozone depletion and the corresponding increase in UV radiation has been shown
to lead to higher incidents of cancer as well as global warming. When viewed from a global
perspective, ozone depletion holds an enormous potential for damage.
Upper Level vs. Ground Level Ozone Confusion often arises when we hear about the necessity of
the ozone layer and ground level ozone. The ozone layer existing high above the earth is beneficial
but the same compound, when located at ground level, is harmful to humans, animals, crops and
vegetation.
Ground level ozone is a component of smog and forms when hydrocarbons (HC) react with
nitrogen oxides (NOx) in the presence of sunlight and heat.
Montreal Protocol In response to the growing body of evidence demonstrating the detrimental
effects of (CFC)s, 24 countries and the European community met in Montreal, Canada, in 1987 to
establish standards for the control of (CFC)s. Since that time, a total of 132 countries have become
signatories to this agreement leading to an end of production of R12 in December, 1995, in all
developed countries.
As established by the Montreal Protocol, R12 production in developed countries has ceased.
Clean Air Act The United States Congress, acting in response to the Montreal Protocol, banned
production of (CFC)s by the year 2000. Congress also amended the Clean Air Act in an effort to
control both the production and use of (CFC)s for refrigerant applications including mobile vehicle
air conditioning systems.

Refrigerant: Description and Operation
REFRIGERANT
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-Hammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an air conditioning system. Even a
small amount of R-12 added to an R-134a refrigerant system will cause compressor failure,
refrigerant oil sludge or poor air conditioning system performance. In addition, the PolyAlkylene
Glycol (PAG) synthetic refrigerant oils used in an R-134a refrigerant system are not compatible
with the mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a system is not accidentally
contaminated with the wrong refrigerant (R-12). There are also labels posted in the engine
compartment of the vehicle and on the compressor identifying to service technicians that the air
conditioning system is equipped with R-134a.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Fluids > Refrigerant > Component Information > Specifications > Page 1163
Refrigerant: Testing and Inspection
If the air conditioning system does not cool properly, the A/C system performance should be tested.
See A/C Performance for the procedures. If the A/C system refrigerant fill is found to be low or if
the system is empty; a leak at a refrigerant line, connector fitting, component, or component seal is
likely.
An electronic leak detector designed for R-134a refrigerant, or a fluorescent R-134a leak detection
dye and a black light are recommended for locating and confirming refrigerant system leaks. Refer
to the operating instructions supplied by the equipment manufacturer for the proper care and use of
this equipment.
NOTE: A/C SYSTEM ALREADY CONTAINS A FACTORY INSTALLED FLUORESCENT DYE.
An oily residue on or near refrigerant system lines, connector fittings, components, or component
seals can indicate the general location of a possible refrigerant leak. However, the exact leak
location should be confirmed with an electronic leak detector prior to component repair or
replacement.
To detect a leak in the refrigerant system with an electronic leak detector, perform one of the
following procedures:
SYSTEM EMPTY
1. Evacuate the refrigerant system. 2. Connect and dispense 0.283 kilograms (0.625 pounds or 10
ounces) of R-134a refrigerant into the evacuated refrigerant system. 3. Position the vehicle in a
wind-free work area. This will aid in detecting small leaks. 4. With the engine not running, use an
electronic R-134a leak detector and search for leaks. Because R-134a refrigerant is heavier than
air, the leak
detector probe should be moved slowly along the bottom side of all refrigerant lines, connector
fittings and components.
5. To inspect the front evaporator coil for leaks, insert the electronic leak detector probe into the
center instrument panel outlet and the floor duct
outlet. Set the front blower motor switch to the lowest speed position, and the mode control switch
to the recirculation mode (Max-A/C).
6. To inspect for leaks in the rear evaporator, put the rear system in the floor mode and place the
probe in the rear unit floor outlet.
SYSTEM LOW
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks. 2. Bring the
refrigerant system up to operating temperature and pressure. This is done by allowing the engine
to run with the air conditioning system
turned on for five minutes.
3. With the engine not running, use an electronic R-134a leak detector and search for leaks.
Because R-134a refrigerant is heavier than air, the leak
detector probe should be moved slowly along the bottom side of all refrigerant lines, connector
fittings and components.
4. To inspect the evaporator coil for leaks, insert the electronic leak detector probe into the center
instrument panel outlet and the floor duct outlet.
Set the front blower motor switch to the lowest speed position, and the mode control switch to the
recirculation mode (Max-A/C).
5. To detect a leak in the rear evaporator, put the rear system in the floor mode and place the
probe in the rear unit floor outlet.

Refrigerant - Recovery
Refrigerant: Service and Repair Refrigerant - Recovery
A R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J22 10 must be
used to recover the refrigerant from an R-134a refrigerant system. Refer to the operating
instructions supplied by the equipment manufacturer for the proper care and use of this equipment.

Refrigerant: Service and Repair Refrigerant - Evacuate
If the refrigerant system has been open to the atmosphere, it must be evacuated before the system
can be charged. If moisture and air enters the system and becomes mixed with the refrigerant, the
compressor head pressure will rise above acceptable operating levels. This will reduce the
performance of the air conditioner and damage the compressor. Evacuating the refrigerant system
will remove the air and boil the moisture out of the system at near room temperature. To evacuate
the refrigerant system, use the following procedure:
1. Connect a R-134a refrigerant recovery/recycling/charging station that meets SAE Standard
J2210 and a manifold gauge set to the refrigerant
system of the vehicle.
2. Open the low and high side valves and start the charging station vacuum pump. When the
suction gauge reads 88 kPa (26 in. Hg.) vacuum or
greater, close all of the valves and turn OFF the vacuum pump. a. If the refrigerant system fails to
reach the specified vacuum, the system has a leak that must be corrected. See Refrigerant System
Leaks in the
Diagnosis and Testing for the procedures.
b. If the refrigerant system maintains the specified vacuum for five minutes, restart the vacuum
pump, open the suction and discharge valves and
evacuate the system for an additional ten minutes.
3. Close all of the valves, and turn OFF the charging station vacuum pump. 4. The refrigerant
system is now ready to be charged with R-134a refrigerant. See Refrigerant System Charge in the
Service Procedures.

Refrigerant Oil: Service and Repair
REFRIGERANT OIL - FRONT
The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, PolyAlkylene Glycol
(PAG), wax-free lubricant. Mineral-based R-12 refrigerant oils are not compatible with PAG Oils
and should never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each contains a different additive package. The
SD7H15 compressor used in this vehicle is designed to use an SP-20 PAG refrigerant oil. Use only
refrigerant oil of this same type to service the refrigerant system.
After performing any refrigerant recovery or recycling operation, always replenish the refrigerant
system with the same amount of the recommended refrigerant oil as was removed. Too little
refrigerant oil can cause compressor damage, and too much can reduce air conditioning system
performance.
PAG refrigerant oil is much more hygroscopic than mineral oil, and will absorb any moisture it
comes into contact with, even moisture in the air. The PAG oil container should always be kept
tightly capped until it is ready to be used. After use, recap the oil container immediately to prevent
moisture contamination.
REFRIGERANT OIL LEVEL - FRONT
When an air conditioning system is assembled at the factory, all components except the
compressor are refrigerant oil free. After the refrigerant system has been charged and operated,
the refrigerant oil in the compressor is dispersed throughout the refrigerant system. The
evaporator, filter-drier, condenser, and compressor will each retain a significant amount of the
needed refrigerant oil.
It is important to have the correct amount of oil in the refrigerant system. This ensures proper
lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil
will reduce the cooling capacity of the air conditioning system.
It will not be necessary to check the oil level in the compressor or to add oil, unless there has been
an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting,
a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant
oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at
the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant Oil Capacities Chart
Refrigerant oil must be added when a filter-drier, evaporator coil, or condenser are replaced. See
the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be
drained from the old compressor and measured. Drain all of the refrigerant oil from the new
compressor, then fill the new compressor with the same amount of refrigerant oil that was drained
out of the old compressor.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Circuit Breaker: Description and Operation
An automatic resetting circuit breaker in the junction block is used to protect the power seat system
circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition
caused by an obstructed or stuck seat adjuster.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.
An automatic resetting circuit breaker in the junction block is used to protect the power window
system circuit. The circuit breaker can protect the system from a short circuit, or from an overload
condition caused by an obstructed or stuck window glass or regulator.
The circuit breaker cannot be repaired and, if faulty, it must be replaced.
1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker slightly, but be
certain that the circuit breaker terminals still
contact the terminals in the junction block cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground. 3. With the voltmeter
positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither
terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as
required.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information >
Diagrams > Diagram Information and Instructions > Page 1246
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Maintenance > Fuses and Circuit Breakers > Fuse Block > Component Information >
Diagrams > Diagram Information and Instructions > Page 1247
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Fuse Block: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation
Troubleshooting Tests
Fig.6 Electrostatic Discharge Symbol
STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES
All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When
handling any component with this symbol, comply with the following procedures to reduce the
possibility of electrostatic charge build up on the body and inadvertent discharge into the
component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Fuse Block: Description and Operation
Fig. 5 Junction Block Location
An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel
cover (Fig. 5). The JB serves to simplify and centralize numerous electrical components, and to
distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the
need for numerous splice connections and serves in place of a bulkhead connector between many
of the engine compartment, instrument panel, and body wire harnesses. The JB houses up to
nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type
automatic resetting circuit breakers, and two International Standards Organization (ISO) relays
(one standard-type and one micro-type).
The molded plastic JB housing has integral mounting brackets that are secured with two screws to
the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse
access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are
located on the back of the fuse access cover, as well as an adhesive-backed fuse layout map to
ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB
housing is faulty or damaged, the entire JB unit must be replaced.
All of the circuits entering and leaving the JB do so through up to nine wire harness connectors,
which are connected to the JB through integral connector receptacles molded into the JB housing.
Internal connection of all of the JB circuits is accomplished by an intricate combination of hard
wiring and bus bars. Refer to Junction Block for the location of complete JB circuit diagrams.

Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. The MIL is
located in the Information Center area of the instrument cluster overlay, to the left of center. The
MIL consists of a stencilled cutout of the International Control and Display Symbol icon for "Engine"
in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents
the indicator from being clearly visible when it is not illuminated. An amber lens behind the cutout in
the opaque layer of the overlay causes the icon to appear in amber through the translucent outer
layer of the overlay when the indicator is illuminated from behind by a Light Emitting Diode (LED)
soldered onto the instrument cluster electronic circuit board. The MIL is serviced as a unit with the
instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) has recorded a Diagnostic Trouble Code (DTC) for an On-Board
Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is controlled by
a transistor on the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the PCM over the Programmable Communications Interface
(PCI) data bus. The MIL Light Emitting Diode (LED) receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the ON or Start positions; therefore, the LED will always be OFF when the
ignition switch is in any position except ON or Start. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn ON the MIL for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the indicator is illuminated
for about seven seconds as a bulb test.
- PCM Lamp-ON Message - Each time the cluster receives a lamp-on message from the PCM, the
indicator will be illuminated. The indicator can be flashed ON and OFF, or illuminated solid, as
dictated by the PCM message. For some DTC's, if a problem does not recur, the PCM will send a
lamp-off message automatically. Other DTC's may require that a fault be repaired and the PCM be
reset before a lamp-OFF message will be sent. For more information on the PCM, and the DTC set
and reset parameters, (Refer to EMISSIONS CONTROL - OPERATION).
- Communication Error - If the cluster receives no lamp-on message from the PCM for twenty
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid lamp-ON message is
received from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON during the bulb check portion of the test to confirm the functionality of the LED and the cluster
control circuitry.
The PCM continually monitors the fuel and emissions system circuits and sensors to decide
whether the system is in good operating condition. The PCM then sends the proper lamp-ON or
lamp-OFF messages to the instrument cluster. If the instrument cluster turns ON the MIL after the
bulb test, it may indicate that a malfunction has occurred and that the fuel and emissions systems
may require service. For proper diagnosis of the fuel and emissions systems, the PCM, the PCI
data bus, or the message inputs to the instrument cluster that control the MIL, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.

Wheels: Description and Operation
DESCRIPTION
The rim size is on the vehicle safety certification label located on the drivers door shut face. The
size of the rim is determined by the drivetrain package. Original equipment wheels/rims are
designed for operation up to the specified maximum vehicle capacity.
Fig. 1
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges and rim drop well called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

Rocker Arm Assembly: Testing and Inspection
DIAGNOSIS AND TESTING-HYDRAULIC LASH ADJUSTER
A tappet-like noise may be produced from several items. Check the following items. 1. Engine oil
level too high or too low. This may cause aerated oil to enter the adjusters and cause them to be
spongy. 2. Insufficient running time after rebuilding cylinder head. Low speed running up to I hour
may be required. 3. Turn engine off and let set for a few minutes before restarting. Repeat this
several times after engine has reached normal operating temperature. 4. Low oil pressure. 5. The
oil restrictor in cylinder head gasket or the oil passage to the cylinder head is plugged with debris.
6. Air ingested into oil due to broken or cracked oil pump pick up. 7. Worn valve guides. 8. Rocker
arm ears contacting valve spring retainer. 9. Rocker arm loose, adjuster stuck or at maximum
extension and still leaves lash in the system.
10. Oil leak or excessive cam bore wear in cylinder head. 11. Faulty lash adjuster.
- Check lash adjusters for sponginess while installed in cylinder head and cam on camshaft at base
circle. Depress part of rocker arm over adjuster. Normal adjusters should feel very firm. Spongy
adjusters can be bottomed out easily.
- Remove suspected lash adjusters, and replace.
- Before installation, make sure adjusters are at least partially full of oil. This can be verified by little
or no plunger travel when lash adjuster is depressed.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Block Assembly > Connecting Rod Bearing
> Component Information > Specifications > Page 1423
Misaligned or bent connecting rods can cause abnormal wear on pistons, piston rings, cylinder
walls, connecting rod bearings and crankshaft connecting rod journals. If wear patterns or damage
to any of these components indicate the probability of a misaligned connecting rod, inspect it for
correct rod alignment. Replace misaligned, bent or twisted connecting rods. 1. Wipe the oil from the
connecting rod journal. 2. Lubricate the upper bearing insert and install in connecting rod.
3. Use piston ring compressor and Guide Pins Special Tool 8507 (Fig. 53) to install the rod and
piston assemblies. The oil slinger slots in the rods
must face front of the engine. The "F"s near the piston wrist pin bore should point to the front of the
engine.
4. Install the lower bearing insert in the bearing cap. The lower insert must be dry. Place strip of
Plastigage across full width of the lower insert at the
center of bearing cap. Plastigage must not crumble in use. If brittle, obtain fresh stock.
5. Install bearing cap and connecting rod on the journal and tighten bolts to 27 Nm (20 ft. lbs.) plus
a 90° turn. DO NOT rotate crankshaft.
Plastigage will smear, resulting in inaccurate indication.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Block Assembly > Connecting Rod Bearing
> Component Information > Specifications > Page 1424
6. Remove the bearing cap and determine amount of bearing-to-journal clearance by measuring
the width of compressed Plastigage (Fig. 54). Refer
to Specifications for the proper clearance. Plastigage should indicate the same clearance across
the entire width of the insert. If the clearance varies, it may be caused by either a tapered journal,
bent connecting rod or foreign material trapped between the insert and cap or rod.
7. If the correct clearance is indicated, replacement of the bearing inserts is not necessary.
Remove the Plastigage from crankshaft journal and
bearing insert. Proceed with installation.
8. If bearing-to-journal clearance exceeds the specification, determine which services bearing set
to use the bearing sizes are as follows: 9. Repeat the Plastigage measurement to verify your
bearing selection prior to final assembly.
10. Once you have selected the proper insert, install the insert and cap. Tighten the connecting rod
bolts to 27 Nm (20 ft. lbs.) plus a 90° turn.
Slide snug-fitting feeler gauge between the connecting rod and crankshaft journal flange (Fig. 55).

Piston: Description and Operation
DESCRIPTION
CAUTION: Do not use a metal stamp to mark connecting rods as damage may result, instead use
ink or a scratch awl.
The pistons are made of a high strength aluminum alloy. The anodized top ring groove and crown
has been replaced with a coated top ring that is blue in color. Piston skirts are coated with a solid
lubricant (Molykote) to reduce friction and provide scuff resistance. The connecting rods are made
of forged powdered metal, with a "fractured cap" design. A pressed fit piston pin is used to attach
the piston and connecting rod.

Piston: Procedures
Cleaning and Inspection
CLEANING
CAUTION: DO NOT use a wire wheel or other abrasive cleaning devise to clean the pistons or
connecting rods. The pistons have a Moly coating, this coating must not be damaged.
1. Using a suitable cleaning solvent clean the pistons in warm water and towel dry. 2. Use a wood
or plastic scraper to clean the ring land grooves.
CAUTION: DO NOT remove the piston pin from the piston and connecting rod assembly.
INSPECTION
Check the connecting rod journal for excessive wear, taper and scoring.
4. Mark connecting rod and bearing cap positions using a permanent ink marker or scribe tool (Fig.
74)
Check the connecting rod for signs of twist or bending. Check the piston for taper and elliptical
shape before it is fitted into the cylinder bore. Check the piston for scoring, or scraping marks in the
piston skirts. Check the ring lands for cracks and/or deterioration.
Piston to Cylinder Bore Fitting
STANDARD PROCEDURE-PISTON FITTING
1. To correctly select the proper size piston, a cylinder bore gauge, capable of reading in 0.003
mm. (0.0001 inch) INCREMENTS is required. If a
bore gauge is not available, do not use an inside micrometer.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Cylinder Block Assembly > Piston, Engine >
Component Information > Service and Repair > Procedures > Page 1470
2. Measure the inside diameter of the cylinder bore at a point 38.0 mm (1.5 inches) below top of
bore. Start perpendicular (across or at 90 degrees)
to the axis of the crankshaft at point A and then take an additional bore reading 90 degrees to that
at point B (Fig. 73).
3. The coated pistons will be serviced with the piston pin and connecting rod pre-assembled.
4. The coating material is applied to the piston after the final piston machining process. Measuring
the outside diameter of a coated piston will not
provide accurate results (Fig. 72). Therefore measuring the inside diameter of the cylinder bore
with a dial Bore Gauge is MANDATORY. To correctly select the proper size piston, a cylinder bore
gauge capable of reading in 0.003 mm (0.0001 inch) increments is required.
5. Piston installation into the cylinder bore requires slightly more pressure than that required for
non-coated pistons. The bonded coating on the
piston will give the appearance of a line-to-line fit with the cylinder bore.

Rocker Arm Assembly: Testing and Inspection
DIAGNOSIS AND TESTING-HYDRAULIC LASH ADJUSTER
A tappet-like noise may be produced from several items. Check the following items. 1. Engine oil
level too high or too low. This may cause aerated oil to enter the adjusters and cause them to be
spongy. 2. Insufficient running time after rebuilding cylinder head. Low speed running up to I hour
may be required. 3. Turn engine off and let set for a few minutes before restarting. Repeat this
several times after engine has reached normal operating temperature. 4. Low oil pressure. 5. The
oil restrictor in cylinder head gasket or the oil passage to the cylinder head is plugged with debris.
6. Air ingested into oil due to broken or cracked oil pump pick up. 7. Worn valve guides. 8. Rocker
arm ears contacting valve spring retainer. 9. Rocker arm loose, adjuster stuck or at maximum
extension and still leaves lash in the system.
10. Oil leak or excessive cam bore wear in cylinder head. 11. Faulty lash adjuster.
- Check lash adjusters for sponginess while installed in cylinder head and cam on camshaft at base
circle. Depress part of rocker arm over adjuster. Normal adjusters should feel very firm. Spongy
adjusters can be bottomed out easily.
- Remove suspected lash adjusters, and replace.
- Before installation, make sure adjusters are at least partially full of oil. This can be verified by little
or no plunger travel when lash adjuster is depressed.

STANDARD PROCEDURE-REFACING
NOTE: Valve seats that are worn or burned can be reworked, provided that correct angle and seat
width are maintained. Otherwise the cylinder head must be replaced.
NOTE: When refacing valves and valve seats, it is important that the correct size valve guide pilot
be used for reseating stones. A true and complete surface must be obtained.
1. Using a suitable dial indicator measure the center of the valve seat Total run out must not
exceed 0.051 mm (0.002 inch). 2. Apply a small amount of Prussian blue to the valve seat, insert
the valve into the cylinder head, while applying light pressure on the valve rotate
the valve. Remove the valve and examine the valve face. If the blue is transferred below the top
edge of the valve face, lower the valve seat using a 15 degree stone. If the blue is transferred to
the bottom edge of the valve face, raise the valve seat using a 65 degree stone.
3. When the seat is properly positioned the width of the intake seat must be 1.75 - 2.36 mm.
(0.0689 0.0928 inch) and the exhaust seat must be 1.71 2.32 mm (0.0673 - 0.0911 inch).
4. Check the valve spring installed height after refacing the valve and seat. The installed height for
both intake and exhaust valve springs must not
exceed 41.44 mm. (1.6315 inch).

Drive Belt: Testing and Inspection
VISUAL DIAGNOSIS
When diagnosing serpentine accessory drive belts, small cracks that run across the ribbed surface
of the belt from rib to rib (Fig. 9), are considered normal. These are not a reason to replace the belt.
However, cracks running along a rib (not across) are not normal. Any belt with cracks running
along a rib must be replaced (Fig. 9). Also replace the belt if it has excessive wear, frayed cords or
severe glazing. Refer to ACCESSORY DRIVE BELT DIAGNOSIS CHART for further belt
diagnosis.
NOISE DIAGNOSIS
Noises generated by the accessory drive belt are most noticeable at idle. Before replacing a belt to
resolve a noise condition, inspect all of the accessory drive pulleys for alignment, glazing, or
excessive end play.

NOTE:
THIS BULLETIN APPLIES TO ALL DAIMLERCHRYSLER MODELS/ENGINES BUILT BEFORE
AND AFTER THE 2001 MODEL YEAR.
DISCUSSION Engine oil additives/supplements (EOS) should not be used to enhance engine oil
performance. Engine oil additives/supplements should not be used to extend engine oil change
intervals. No additive is known to be safe for engine durability and can degrade emission
components. Additives can contain undesirable materials that harm the long term durability of
engines by:
^ Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard
Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10%
Phosphorus to protect the vehicles emissions performance. Addition of engine oil
additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder
efforts to guarantee our emissions performance to 80,000 miles and new requirements of 150,000
miles.
^ Altering the viscosity characteristics of the engine oil so that it no longer meets the requirements
of the specified viscosity grade.
^ Creating potential for an undesirable additive compatibility interaction in the engine crankcase.
Generally it is not desirable to mix additive packages from different suppliers in the crankcase;
there have been reports of low temperature engine failures caused by additive package
incompatibility with such mixtures.

Engine Oil: Service and Repair
STANDARD PROCEDURE - ENGINE OIL SERVICE
WARNING: NEW OR USED ENGINE OIL CAN BE IRRITATING TO THE SKIN. AVOID
PROLONGED OR REPEATED SKIN CONTACT WITH ENGINE OIL. CONTAMINANTS IN USED
ENGINE OIL, CAUSED BY INTERNAL COMBUSTION, CAN BE HAZARDOUS TO YOUR
HEALTH. THOROUGHLY WASH EXPOSED SKIN WITH SOAP AND WATER. DO NOT WASH
SKIN WITH GASOLINE, DIESEL FUEL, THINNER, OR SOLVENTS, HEALTH PROBLEMS CAN
RESULT. DO NOT POLLUTE, DISPOSE OF USED ENGINE OIL PROPERLY.
ENGINE OIL SPECIFICATION
CAUTION: Do not use non-detergent or straight mineral oil when adding or changing crankcase
lubricant. Engine failure can result.
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Service Grade Certified. MOPAR provides engine oils that conform to
this service grade.
SAE VISCOSITY
An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with
multiple viscosities such as 5W-30 or 1OW-30 in the 4.7L engines. These are specified with a dual
SAE viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine
oil that is best suited to your particular temperature range and variation (Fig. 97).
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY
CONSERVING is located on the label of an engine oil container.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have been adopted to aid in the proper selection of
engine oil. The identifying notations are located on the label of engine oil plastic bottles and the top
of engine oil cans (Fig. 98).
OIL LEVEL INDICATOR (DIPSTICK)
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Engine Lubrication > Engine Oil > Component
Information > Specifications > Page 1544
The engine oil level indicator is located at the right rear of the engine on the 4.7L engines. (Fig. 99).
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles). Unless the engine has
exhibited loss of oil pressure, run the engine for about five minutes before checking oil level.
Checking engine oil level on a cold engine is not accurate. To ensure proper lubrication of an
engine, the engine oil must be maintained at an acceptable level. The acceptable levels are
indicated between the ADD and SAFE marks on the engine oil dipstick. 1. Position vehicle on level
surface. 2. With engine OFF, allow approximately ten minutes for oil to settle to bottom of
crankcase, remove engine oil dipstick. 3. Wipe dipstick clean. 4. Install dipstick and verify it is
seated in the tube. 5. Remove dipstick, with handle held above the tip, take oil level reading. 6. Add
oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules. Run engine
until achieving normal operating temperature. 1. Position the vehicle on a level surface and turn
engine off. 2. Hoist and support vehicle on safety stands. 3. Remove oil fill cap. 4. Place a suitable
drain pan under crankcase drain. 5. Remove drain plug from crankcase and allow oil to drain into
pan. Inspect drain plug threads for stretching or other damage. Replace drain plug if
damaged.
6. Install drain plug in crankcase. 7. Lower vehicle and fill crankcase with specified type and
amount of engine oil. 8. Install oil fill cap. 9. Start engine and inspect for leaks.
10. Stop engine and inspect oil level.

Oil Pressure Gauge: Description and Operation
An oil pressure gauge is standard equipment on all instrument clusters. The oil pressure gauge is
located in the upper right quadrant of the instrument cluster, above the fuel gauge. The oil pressure
gauge consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry
and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L" (or Low) to "H"
(or High). An International Control and Display Symbol icon for "Engine Oil" is located on the
cluster overlay, in the center of the gauge directly above the hub of the gauge needle. The oil
pressure gauge graphics are white against a black field except for a single red graduation at the
low end of the gauge scale, making them clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned ON, the white graphics appear blue-green and the red graphics
appear red. The orange gauge needle is internally illuminated. Gauge illumination is provided by
replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic
circuit board. The oil pressure gauge is serviced as a unit with the instrument cluster.
The oil pressure gauge gives an indication to the vehicle operator of the engine oil pressure. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The oil pressure gauge is an air core
magnetic unit that receives battery current on the instrument cluster electronic circuit board through
the fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions. The cluster is programmed to move the gauge needle back to the low end of the scale
after the ignition switch is turned to the OFF position. The instrument cluster circuitry controls the
gauge needle position and provides the following features:
- Engine Oil Pressure Message - The instrument cluster circuitry restricts the oil pressure gauge
needle operation in order to provide readings that are consistent with customer expectations. Each
time the cluster receives a message from the PCM indicating the engine oil pressure is between
about 6.9 kPa (1 psi) and 137.9 kPa (20 psi), the cluster holds the gauge needle at a point about
11 degrees above the low end of normal increment on the gauge scale. Each time the cluster
receives a message from the PCM indicating the engine oil pressure is between about 517.1 kPa
(75 psi) and 755 kPa (109.5 psi), the cluster holds the gauge needle at a point about 7.4 degrees
below the high end of normal increment on the gauge scale. When the cluster receives messages
from the PCM indicating the engine oil pressure is between about 137.9 kPa (20 psi) and 517.1
kPa (75 psi), the gauge needle is moved to the actual pressure position on the gauge scale.
- Engine Oil Pressure Low Message - Each time the cluster receives a message from the PCM
indicating the engine oil pressure is below about 6.9 kPa (1 psi), the gauge needle is moved to the
L (Low) graduation at the far left end of the gauge scale, the check gauges indicator is illuminated,
and a single chime tone is generated. The gauge needle remains at the low end of the scale and
the check gauges indicator remains illuminated until the cluster receives a message from the PCM
indicating that the engine oil pressure is above about 6.9 kPa (1 psi), or until the ignition switch is
turned to the OFF position, whichever occurs first. The cluster will only turn the check gauges
indicator lamp ON in response to an engine oil pressure low message if the engine speed message
is greater than zero.
- Engine Oil Pressure High Message - Each time the cluster receives a message from the PCM
indicating the engine oil pressure is above about 755 kPa (109.5 psi), the gauge needle is moved
to the H (High) graduation at the far right end of the gauge scale. The gauge needle remains at the
high end of the scale until the cluster receives a message from the PCM indicating that the engine
oil pressure is below about 755 kPa (109.5 psi), or until the ignition switch is turned to the OFF
position, whichever occurs first.
- Message Failure - If the cluster fails to receive an engine oil pressure message, it will hold the
gauge needle at the last indication until a new message is received, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the engine oil pressure sensor to determine the engine oil pressure.
The PCM then sends the proper engine oil pressure messages to the instrument cluster. For
further diagnosis of the oil pressure gauge or the instrument cluster circuitry that controls the
gauge, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). If the instrument cluster
turns ON the check gauges indicator due to a low oil pressure gauge reading, it may indicate that
the engine or the engine oiling system requires service. For proper diagnosis of the engine oil
pressure sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster that
control the oil pressure gauge, a DRB III scan tool is required. Refer to the appropriate diagnostic
information.

Crankshaft Main Bearing Seal: Testing and Inspection
DIAGNOSIS AND TESTING-REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in the rear seal area of the
engine, a more involved inspection is necessary. The following steps should be followed to help
pinpoint the source of the leak. If the leakage occurs at the crankshaft rear oil seal area: 1.
Disconnect the battery. 2. Raise the vehicle. 3. Remove torque converter or clutch housing cover
and inspect rear of block for evidence of oil. Use a black light to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaft damage. b. Where leakage
tends to run straight down, possible causes are a porous block, distributor seal, camshaft bore cup
plugs, oil galley pipe plugs,
oil filter runoff, and main bearing cap to cylinder block mating surfaces. See Engine, for proper
repair procedures of these items.
4. If no leaks are detected, pressurized the crankcase.
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch for leakage. If a leak is
detected between the crankshaft and seal while slowly
turning the crankshaft, it is possible the crankshaft seal surface is damaged. The seal area on the
crankshaft could have minor nicks or scratches that can be polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks or
scratches. The crankshaft seal flange is specially machined to complement the function of the rear
oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until
disassembled. Refer to components inspections on
possible causes and corrections.
7. After the oil leak root cause and appropriate corrective action have been identified.

Timing Chain: Testing and Inspection
STANDARD PROCEDURE-MEASURING TIMING CHAIN WEAR
NOTE: This procedure must be performed with the timing chain cover removed.
1. Remove the timing chain cover..
2. To determine if the secondary timing chains are worn, rotate the engine clockwise until
maximum tensioner piston extension is obtained. Measure
the distance between the secondary timing chain tensioner housing and the step ledge on the
piston (Fig. 123). The measurement at point (A) must be less than 15 mm (0.5906 inches).
3. If the measurement exceeds the specification the secondary timing chains are worn and require
replacement.
NOTE: If the secondary chains are to be replaced the primary chain must also be replaced.

Spark Plug: Description and Operation
This engine are equipped with "fired in suppressor seal" type spark plugs using a copper core
ground electrode.
Because of the use of an aluminum cylinder head on this engine, spark plug torque is very critical.
To prevent possible pre-ignition and/or mechanical engine damage, the correct type/heat
range/number spark plug must be used.
Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken
porcelain insulators. Keep plugs arranged in the order in which they were removed from the
engine. A single plug displaying an abnormal condition indicates that a problem exists in the
corresponding cylinder. Replace spark plugs at the intervals recommended in Lubrication and
Maintenance.
Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or
oil fouled. Also refer to Spark Plug Conditions.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator and will cause plug misfire.

Spark Plug: Testing and Inspection
SPARK PLUG CONDITIONS
Fig. 20 Normal Operation And Cold (Carbon) Fouling
Normal Operating The few deposits present on the spark plug will probably be light tan or slightly
gray in color. This is evident with most grades of commercial gasoline. There will not be evidence
of electrode burning. On this engine gap growth will not average more than approximately 0.0015
in per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be
cleaned, have the electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a Manganese Additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits.
Cold Fouling/carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits
that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may
be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set
of spark plugs may be caused by a clogged air cleaner element or repeated short operating times
(short trips).
Wet Fouling Or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In
older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause
wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal
oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the
fouled plugs.

Plug > Component Information > Specifications > Page 1685
Fig. 21 Oil Or Ash Encrusted
Oil Or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine
condition for the cause of oil entry into that particular combustion chamber.
Fig. 22 Electrode Gap Bridging
Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion
chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving.
When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge
the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap
bridging can be cleaned using standard procedures.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark
Plug > Component Information > Specifications > Page 1686
Fig. 23 Scavenger Deposits
Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to
be harmful, but this is a normal condition caused by chemical additives in certain fuses. These
additives are designed to change the chemical nature of deposits and decrease spark plug misfire
tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the
deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in
condition and can be cleaned using standard procedures.
Fig. 24 Chipped Electrode Insulator
Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center
electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation
can also separate the insulator from the center electrode. Spark plugs with this condition must be
replaced.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Tune-up and Engine Performance Checks > Spark
Plug > Component Information > Specifications > Page 1687
Fig. 25 Preignition Damage
Preignition Damage Preignition damage is usually caused by excessive combustion chamber
temperature. The center electrode dissolves first and the ground electrode dissolves somewhat
latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat
range rating for the engine. Determine if ignition timing is over advanced or if other operating
conditions are causing engine overheating. (The heat range rating refers to the operating
temperature of a particular type spark plug. Spark plugs are designed to operate within specific
temperature ranges. This depends upon the thickness and length of the center electrodes porcelain
insulator.)
Fig. 26 Spark Plug Overheating
Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that
also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch
per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be
used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause
spark plug overheating.

Spark Plug: Service and Repair
REMOVAL
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
In this engine: Each individual spark plug is located under each ignition coil. Each individual ignition
coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
1. In this engine: Prior to removing spark plug, spray compressed air around base of ignition coil at
cylinder head. This will help prevent foreign
material from entering combustion chamber.
2. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. If
equipped with this engine, also check condition of
coil O-ring and replace as necessary.
3. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
The plugs may be cleaned using commercially available spark plug cleaning equipment. After
cleaning, file center electrode flat with a small point file or jewelers file before adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean spark plugs. Metallic deposits will
remain on spark plug insulator and will cause plug misfire.
INSTALLATION
CAUTION: This engine is equipped with copper core ground electrode spark plugs. They must be
replaced with the same type/number spark plug as the original. If another spark plug is substituted,
pre-ignition will result.
Special care should be taken when installing spark plugs into the cylinder head spark plug wells.
Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. In this engine:
Tighten spark plugs to 27 Nm (20 ft. lbs.) torque. 3. In this engine: Before installing coil(s), check
condition of coil O-ring and replace as necessary. To aid in coil installation, apply silicone to coil
O-ring.
4. In this engine: Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

Water Pump: Description and Operation
DESCRIPTION-WATER PUMP
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core. The pump is driven from the engine
crankshaft by a single serpentine drive belt. The water pump impeller is pressed onto the rear of a
shaft that rotates in bearings pressed into the housing. The housing has two small holes to allow
seepage to escape. The water pump seals are lubricated by the antifreeze in the coolant mixture.
No additional lubrication is necessary.
Both heater hoses are connected to fittings on the timing chain front cover. The water pump is also
mounted directly to the timing chain cover and is equipped with a non serviceable integral pulley.
DESCRIPTION-WATER PUMP BYPASS

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Engine > Water Pump > Component Information >
Specifications > Page 1700
The 4.7L engine uses an internal water/coolant bypass system. The design uses galleries in the
timing chain cover to circulate coolant during engine warm-up preventing the coolant from flowing
through the radiator. The thermostat uses a stub shaft located at the rear of the thermostat to
control flow through the bypass gallery.
OPERATION-WATER PUMP
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core, this coolant absorbs the heat generated when
the engine is running. The pump is driven by the engine crankshaft via a drive belt.
OPERATION-WATER PUMP BYPASS
When the thermostat is in the closed position the bypass gallery is not obstructed allowing 100%
flow. When the thermostat is in the open position the stub shaft enters the bypass gallery
obstructing bypass coolant flow by 50%. This design allows the coolant to reach operating
temperature quickly when cold, while adding extra cooling during normal temperature operation.

Coolant Reservoir: Description and Operation
DESCRIPTION
The coolant recovery container is integral to the upper fan shroud assembly and is made of high
temperature plastic.
OPERATION
The coolant recovery container works in conjunction with the radiator pressure cap. It utilizes
thermal expansion and contraction of coolant to keep coolant free of trapped air. It provides a
volume for expansion and contraction of coolant. It also provides a convenient and safe method for
checking coolant level and adjusting level at atmospheric pressure. This is done without removing
the radiator pressure cap. The system also provides some reserve coolant to the radiator to cover
minor leaks and evaporation or boiling losses. As the engine cools, a vacuum is formed in the
cooling system of both the radiator and engine. Coolant will then be drawn from the coolant tank
and returned to a proper level in the radiator.

1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Radiator Cooling Fan Motor: Description and Operation
DESCRIPTION
The fan is electrically controlled by the powertrain control module (PCM) through the fan control
relay. This relay is located in the power distribution center (PDC). For the location of the relay
within the PDC, refer to label on PDC cover.
OPERATION
The PCM regulates fan operation based on input from the engine coolant temperature sensor and
vehicle speed. The fan is not energized during engine cranking regardless of the electrical input
from the engine coolant temperature sensor. However, if engine operating conditions warrant fan
engagement, the fan will run once engine starts. The fan is energized whenever the engine is
running and engine coolant or transmission oil sump temperature is greater than 104°C (220°F) or
air conditioning head pressure is greater than 32 kPa (220 psi). The fan will turn off when engine
coolant or transmission oil sump temperature drops below 102°C (216°F), or air conditioning head
pressure drops to 24.6 kPa (170 psi).

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

HEATER CORE - FRONT
The heater core is located in the HVAC housing, under the instrument panel. It is a heat exchanger
made of rows of tubes and fins.
The heater core is not repairable and if damaged it must be replaced.
Engine coolant is circulated through heater hoses to the heater core at all times. As the coolant
flows through the heater core, heat removed from the engine is transferred to the heater core fins
and tubes. Air directed through the heater core picks up the heat from the heater core fins. The
blend door allows control of the heater output air temperature by controlling how much of the air
flowing through the HVAC housing is directed through the heater core. The blower motor speed
controls the volume of air flowing through the HVAC housing.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.

Temperature Gauge: Locations
The engine coolant temperature gauge is located in the lower left quadrant of the instrument
cluster, below the voltage gauge.

Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Lamps and Indicators - Cooling System >
Temperature Gauge > Component Information > Locations > Page 1788
Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower left quadrant of the instrument cluster, below the
voltage gauge. The engine coolant temperature gauge consists of a movable gauge needle or
pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for all engines. An International
Control and Display Symbol icon for "Engine Coolant Temperature" is located on the cluster
overlay, in the center of the gauge directly above the hub of the gauge needle. The engine coolant
temperature gauge graphics are white against a black field except for a single red graduation at the
high end of the gauge scale, making them clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned ON, the white graphics appear blue-green and the red graphics
appear red. The orange gauge needle is internally illuminated. Gauge illumination is provided by
replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic
circuit board. The engine coolant temperature gauge is serviced as a unit with the instrument
cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) over the Programmable Communications Interface (PCI) data bus. The engine
coolant temperature gauge is an air core magnetic unit that receives battery current on the
instrument cluster electronic circuit board through the fused ignition switch output (run-start) circuit
whenever the ignition switch is in the ON or Start positions. The cluster is programmed to move the
gauge needle back to the low end of the scale after the ignition switch is turned to the OFF
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is between the low end of normal [about 54 °C (130 °F)
and the high end of normal [about 129 °C (264 °F), the gauge needle is moved to the actual
temperature position on the gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is below the low end of normal [about 54 °C (130 °F)],
the gauge needle is held at the "C" increment at the far left end of the gauge scale. The gauge
needle remains at the far left end of the scale until the cluster receives a message from the PCM
indicating that the engine temperature is above about 54 °C (130 °F), or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is above about 122 °C (251 °F), the gauge needle is
moved to the appropriate position on the gauge scale, the check gauges indicator is illuminated,
and a single chime tone is sounded. The check gauges indicator remains illuminated until the
cluster receives a message from the PCM indicating that the engine temperature is below about
119 °C (246 °F), or until the ignition switch is turned to the OFF position, whichever occurs first.
The chime tone feature will only repeat during the same ignition cycle if the check gauges indicator
is cycled OFF and then on again by the appropriate engine temperature messages from the PCM.
- Message Failure - If the cluster fails to receive an engine temperature message, it will hold the
gauge needle at the last indication until a new message is received, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the engine coolant temperature sensor to determine the engine
operating temperature. The PCM then sends the proper engine coolant temperature messages to
the instrument cluster. For further diagnosis of the engine coolant temperature gauge or the
instrument cluster circuitry that controls the gauge, (Refer to INSTRUMENT CLUSTER DIAGNOSIS AND TESTING). If the instrument cluster turns ON the check gauges indicator due to
a high engine temperature gauge reading, it may indicate that the engine or the engine cooling
system requires service. For proper diagnosis of the engine coolant temperature sensor, the PCM,
the PCI data bus, or the message inputs to the instrument cluster that control the engine coolant
temperature gauge, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Radiator Cap: Description and Operation
DESCRIPTION
All cooling systems are equipped with a pressure cap in the radiator upper hose. This cap releases
pressure at some point within a range of 131-to-158 kPa (19-to-23 psi). The pressure relief point (in
pounds) is engraved on top of the cap The cooling system will operate at pressures slightly above
atmospheric pressure. This results in a higher coolant boiling point allowing increased radiator
cooling capacity. The cap contains a spring loaded pressure relief valve. This valve opens when
system pressure reaches the release range of 131-to158 kPa (19-to-23 psi). A rubber gasket seals
the radiator filler neck. This is done to maintain vacuum during coolant cool-down and to prevent
leakage when system is under pressure.
OPERATION
A vent valve in the center of the cap will remain shut as long as the cooling system is pressurized.
As the coolant cools, it contracts and creates a vacuum in cooling system. This causes the vacuum
valve to open and coolant in reserve/overflow tank to be drawn through connecting hose into
radiator. If the vacuum valve is stuck shut, or overflow hose is kinked, radiator hoses will collapse
on cool-down.

RADIATOR CAP-TO-FILLER NECK SEAL
The pressure cap upper gasket (seal) pressure relief can be tested by removing overflow hose
from radiator filler neck nipple. Attach hose of pressure tester tool 7700 (or equivalent) to nipple. It
will be necessary to disconnect hose from its adapter for filler neck. Pump air into radiator. The
pressure cap upper gasket should relieve at 131 kPa (21 psi) and hold pressure at a minimum of
130 kPa. (18.8 psi).
WARNING: THE WARNING WORDS -DO NOT OPEN HOT- ON RADIATOR PRESSURE CAP,
ARE A SAFETY PRECAUTION. WHEN HOT, PRESSURE BUILDS UP IN COOLING SYSTEM.
TO PREVENT SCALDING OR INJURY, RADIATOR CAP SHOULD NOT BE REMOVED WHILE
SYSTEM IS HOT AND/OR UNDER PRESSURE.
Do not remove radiator cap at any time except for the following purposes: 1. Check and adjust
antifreeze freeze point. 2. Refill system with new antifreeze. 3. Conducting service procedures. 4.
Checking for vacuum leaks.
WARNING: IF VEHICLE HAS BEEN RUN RECENTLY, WAIT AT LEAST 15 MINUTES BEFORE
REMOVING RADIATOR CAP. WITH A RAG, SQUEEZE RADIATOR UPPER HOSE TO CHECK
IF SYSTEM IS UNDER PRESSURE. PLACE A RAG OVER CAP AND WITHOUT PUSHING CAP
DOWN, ROTATE IT COUNTERCLOCKWISE TO FIRST STOP. ALLOW FLUID TO ESCAPE
THROUGH THE COOLANT RESERVE/ OVERFLOW HOSE INTO RESERVE/OVERFLOW TANK.
SQUEEZE RADIATOR UPPER HOSE TO DETERMINE WHEN PRESSURE HAS BEEN
RELEASED. WHEN COOLANT AND STEAM STOP BEING PUSHED INTO TANK AND SYSTEM
PRESSURE DROPS, REMOVE RADIATOR CAP COMPLETELY.

Radiator Cap: Testing and Inspection Radiator Cap Testing
RADIATOR CAP
Remove cap from radiator. Be sure that sealing surfaces are clean. Moisten rubber gasket with
water and install cap on pressure tester 7700 or an equivalent.
Operate tester pump to bring pressure to 138 kPa (20 psi) on gauge. If pressure cap fails to hold
pressure of at least 131 kPa (19 psi) replace cap. Refer to following CAUTION.
The pressure cap may test properly while positioned on tool 7700 (or equivalent). It may not hold
pressure or vacuum when installed on radiator. If so, inspect radiator filler neck and cap's top
gasket for damage. Also inspect for dirt or distortion that may prevent cap from sealing properly.
CAUTION: Radiator pressure testing tools are very sensitive to small air leaks, which will not cause
cooling system problems. A pressure cap that does not have a history of coolant loss should not be
replaced just because it leaks slowly when tested with this tool. Add water to tool. Turn tool upside
down and recheck pressure cap to confirm that cap needs replacement.

Radiator Cap: Service and Repair
CLEANING
Use only a mild soap and water to clean the radiator cap. Using any type solvent may cause
damage to the seal in the radiator cap.
INSPECTION
Hold cap at eye level, right side up. The vent valve at bottom of cap should open. If rubber gasket
has swollen and prevents vent valve from opening, replace cap. Hold cap at eye level, upside
down. If any light can be seen between vent valve and rubber gasket, replace cap. Do not use a
replacement cap that has a spring to hold vent shut. A replacement cap must be the type designed
for a coolant reserve/overflow system with a completely sealed diaphragm spring and a rubber
gasket. This gasket is used to seal to radiator filler neck top surface. Use of proper cap will allow
coolant return to radiator.

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Temperature Gauge: Locations
The engine coolant temperature gauge is located in the lower left quadrant of the instrument
cluster, below the voltage gauge.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Temperature Gauge > Component
Information > Locations > Page 1831
Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower left quadrant of the instrument cluster, below the
voltage gauge. The engine coolant temperature gauge consists of a movable gauge needle or
pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for all engines. An International
Control and Display Symbol icon for "Engine Coolant Temperature" is located on the cluster
overlay, in the center of the gauge directly above the hub of the gauge needle. The engine coolant
temperature gauge graphics are white against a black field except for a single red graduation at the
high end of the gauge scale, making them clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned ON, the white graphics appear blue-green and the red graphics
appear red. The orange gauge needle is internally illuminated. Gauge illumination is provided by
replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic
circuit board. The engine coolant temperature gauge is serviced as a unit with the instrument
cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) over the Programmable Communications Interface (PCI) data bus. The engine
coolant temperature gauge is an air core magnetic unit that receives battery current on the
instrument cluster electronic circuit board through the fused ignition switch output (run-start) circuit
whenever the ignition switch is in the ON or Start positions. The cluster is programmed to move the
gauge needle back to the low end of the scale after the ignition switch is turned to the OFF
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is between the low end of normal [about 54 °C (130 °F)
and the high end of normal [about 129 °C (264 °F), the gauge needle is moved to the actual
temperature position on the gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is below the low end of normal [about 54 °C (130 °F)],
the gauge needle is held at the "C" increment at the far left end of the gauge scale. The gauge
needle remains at the far left end of the scale until the cluster receives a message from the PCM
indicating that the engine temperature is above about 54 °C (130 °F), or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is above about 122 °C (251 °F), the gauge needle is
moved to the appropriate position on the gauge scale, the check gauges indicator is illuminated,
and a single chime tone is sounded. The check gauges indicator remains illuminated until the
cluster receives a message from the PCM indicating that the engine temperature is below about
119 °C (246 °F), or until the ignition switch is turned to the OFF position, whichever occurs first.
The chime tone feature will only repeat during the same ignition cycle if the check gauges indicator
is cycled OFF and then on again by the appropriate engine temperature messages from the PCM.
- Message Failure - If the cluster fails to receive an engine temperature message, it will hold the
gauge needle at the last indication until a new message is received, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the engine coolant temperature sensor to determine the engine
operating temperature. The PCM then sends the proper engine coolant temperature messages to
the instrument cluster. For further diagnosis of the engine coolant temperature gauge or the
instrument cluster circuitry that controls the gauge, (Refer to INSTRUMENT CLUSTER DIAGNOSIS AND TESTING). If the instrument cluster turns ON the check gauges indicator due to
a high engine temperature gauge reading, it may indicate that the engine or the engine cooling
system requires service. For proper diagnosis of the engine coolant temperature sensor, the PCM,
the PCI data bus, or the message inputs to the instrument cluster that control the engine coolant
temperature gauge, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Thermostat: Description and Operation
DESCRIPTION
CAUTION: Do not operate an engine without a thermostat, except for servicing or testing.
A pellet-type thermostat controls the operating temperature of the engine by controlling the amount
of coolant flow to the radiator. On all engines the thermostat is closed below 195°F (90°C). Above
this temperature, coolant is allowed to flow to the radiator. This provides quick engine warm up and
overall temperature control. On the 4.7L engine the thermostat is designed to block the flow of the
coolant bypass journal by 50% instead of completely blocking the flow. This design controls coolant
temperature more accurately. The same thermostat is used for winter and summer seasons. An
engine should not be operated without a thermostat, except for servicing or testing. Operating
without a thermostat causes other problems. These are: longer engine warm-up time, unreliable
warm-up performance, increased exhaust emissions and crankcase condensation. This
condensation can result in sludge formation.
OPERATION
The wax pellet is located in a sealed container at the spring end of the thermostat. When heated,
the pellet expands, overcoming closing spring tension and water pump pressure to force the valve
to open.

ON-BOARD DIAGNOSTICS
All gasoline powered models are equipped with On-Board Diagnostics for certain cooling system
components. Refer to On-Board Diagnostics (OBD) for additional information. If the powertrain
control module (PCM) detects low engine coolant temperature, it will record a Diagnostic Trouble
Code (DTC) in the PCM memory. Do not change a thermostat for lack of heat as indicated by the
instrument panel gauge or by poor heater performance unless a DTC is present. Refer to the
Diagnosis for other probable causes. The DTC can also be accessed through the DRB scan tool.
Refer to the appropriate Powertrain Diagnostic Procedures information for diagnostic information
and operation of the DRB scan tool.

Water Pump: Description and Operation
DESCRIPTION-WATER PUMP
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core. The pump is driven from the engine
crankshaft by a single serpentine drive belt. The water pump impeller is pressed onto the rear of a
shaft that rotates in bearings pressed into the housing. The housing has two small holes to allow
seepage to escape. The water pump seals are lubricated by the antifreeze in the coolant mixture.
No additional lubrication is necessary.
Both heater hoses are connected to fittings on the timing chain front cover. The water pump is also
mounted directly to the timing chain cover and is equipped with a non serviceable integral pulley.
DESCRIPTION-WATER PUMP BYPASS
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Engine, Cooling and Exhaust > Cooling System > Water Pump > Component Information >
Specifications > Page 1851
The 4.7L engine uses an internal water/coolant bypass system. The design uses galleries in the
timing chain cover to circulate coolant during engine warm-up preventing the coolant from flowing
through the radiator. The thermostat uses a stub shaft located at the rear of the thermostat to
control flow through the bypass gallery.
OPERATION-WATER PUMP
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold,
radiator core, cooling system hoses and heater core, this coolant absorbs the heat generated when
the engine is running. The pump is driven by the engine crankshaft via a drive belt.
OPERATION-WATER PUMP BYPASS
When the thermostat is in the closed position the bypass gallery is not obstructed allowing 100%
flow. When the thermostat is in the open position the stub shaft enters the bypass gallery
obstructing bypass coolant flow by 50%. This design allows the coolant to reach operating
temperature quickly when cold, while adding extra cooling during normal temperature operation.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Central Timer Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Central Timer Module: Vehicle Damage Warnings
Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could
damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of
the original problem more difficult,
Road Testing A Complaint Vehicle
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE
REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB III SCREEN
WHILE IN MOTION. DO NOT HANG THE DRB III FROM THE REAR VIEW MIRROR OR
OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB III.

Central Timer Module: Description and Operation Sytem Description
The body system on the 2001 DN consists of a combination of modules that communicate over the
PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus,
information about the operation of vehicle components and circuits is relayed quickly to the
appropriate module(s). All modules receive all the information transmitted on the bus even though
a module may not require all information to perform its function. It will only respond to messages
"addressed" to it through a binary coding process. This method of data transmission significantly
reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the
information about the functioning of all the systems is organized, controlled, and communicated by
the PCI bus, which is described in the vehicle communication of this general information.

AIRBAG SYSTEM
The airbag system is designed to provide increased driver and passenger protection if the vehicle
is involved in a front end collision. The system is most effective when used in conjunction with the
seat belt system.
The Airbag Control Module (ACM) is an electronic module that monitors the airbag system for
proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and
contains the sensor and actuator that is responsible for airbag deployment. There are no external
impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck
at the bottom of the instrument panel. It is located forward of the console. The ACM provides
diagnostic information (DTCs) to the technician through the DRB III via the PCI bus. Some circuits
are tested continuously; others are checked only under certain circumstances. The warning lamp is
driven with messages relayed to the Electro/Mechanical Instrument Cluster (EMIC) from the ACM
via the PCI bus.
The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be
observed by the customer. Whenever the ignition key is turned to the "run" or "start" position, the
airbag control module performs a lamp check by turning the AIRBAG warning lamp ON for 6 - 8
seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to
be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the
system or the circuit that operates the lamp may be shorted to ground. If the lamp comes ON and
stays ON for a period longer than 6 - 8 seconds, then goes OFF, there is usually an intermittent
problem in the system.
WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT.
Seat Belt Tensioner
Front seat belt systems incorporate Tensioner Modules (SBT). At the onset of an impact event
each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to
rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact
will be reduced as will the likelihood of contacting interior components. After an impact that deploys
the airbag, the seat belt tensioner assembly must be replaced.
The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and
stored DTC's if any problem is found.
Airbag Diagnostic Trouble Codes
Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,
diagnostic priority should be given to the active codes.
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic
test procedures contain step-by-step instructions for determining the cause of the trouble codes. It
is not necessary to perform all of the tests in this book to diagnose an individual code.
Always begin by reading the diagnostic trouble codes using the DRB III.
Active diagnostic trouble codes for the airbag system are not permanent and will change the
moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes
are used as a diagnostic tool.
Active Codes
The code becomes active as soon as the malfunction is detected and stored after one minute of
occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going
malfunction. This means that the defect is currently there every time the airbag control module
checks that circuit/function. It is impossible to erase an active code; active codes automatically
erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is
detected, the airbag lamp remains lit for a minimum

Modules - Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 1947
of 12 seconds or as long as the malfunction is present.
Stored Codes
Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or
when the ignition is turned OFF. The exception is the "Loss of Ignition Run Only" code which is an
active code only.
A "stored" code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
When a trouble code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
The minimum time shown for any code will be one minute, even if the code was actually present for
less than one minute. Thus, the time shown for a code that was present for two minutes 13
seconds, for example, would be three minutes.
If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the
malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be
initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same
malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If
the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset
and the diagnostic trouble code will continue to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code
diagnostic test will not locate the source of the problem. In this case, the stored code can indicate
an area to inspect.
If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire
harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes
periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
AUDIO SYSTEM
The factory installed radio receiver communicates on the Programmable Communication Interface
(PCI) data bus network through a separate two-way wire harness connector. This is used for the
remote radio switches that are mounted to the steering wheel, and also used for radio diagnosis
with the DRB III.
The remote radio switches are resistor multiplexed units that are hard wired to the CTM through the
clockspring. The CTM monitors the status of the remote radio switches and sends the proper
switch status messages on the PCI data bus network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by
adjusting the radio settings as requested.
When troubleshooting output shorts or "output" error messages, the following applies: On radios
without an external amplifier, the term "output" refers to the path between the radio and the
speaker. This type of circuit can be monitored all the way through the speaker connections by the
radio assembly. When the radio displays a shorted output DTC with this type of system, the
speaker, radio or wiring could be at fault. The output DTC could refer to a front or rear output or a
left or right output. The reason for the difference is the pairing of the output sections of the radio.
Some are paired left and right, others are paired front and rear.
On radios with an external amplifier, the term "output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of monitoring only this portion and can tell nothing
about the circuit between the amplifier and the speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit. A faulty speaker could not cause this DTC.
CENTRAL TIMER MODULE
The Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or
Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.
The Base and Highline CTM provides the following features: Battery Saver Functions For Exterior and Interior Lamps
- Cargo Lamps
- Chime Warning
- Courtesy Lamps
- Dome Lamps
- Dome Defeat
- Door Ajar Switch Status
- Fog Lamps
- Head Lamp Time Delay
- Intermittent Wiper Controls
- Low and High Beam Head Lamps
- Optical Horn
- Park Lamps

- Remote Radio
- Remote Keyless Entry
- Vehicle Theft Alarm (VTSS)
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
CHIME SYSTEM
The chime system is built into the CTM. There are two chime rates, Low: 50 chimes per minute for
reminders and High: 180 chimes per minute for serious conditions that require immediate attention.
The high rate chime sounds when the key is left in the ignition and the driver's door is open or if the
headlights or the courtesy lights are left on. The low rate chime sounds for any of the other
conditions. There is a variable rate feature that allows the chime to sound continuously for key-in
and headlamp warning as long as the door is open. The seat belt warning chime is activated for six
seconds, and all other chime conditions will activate the chime once at the same time the warning
light on the cluster is illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
COMPASS MINI-TRIP COMPUTER (CMTC)
This system, located in the overhead console, displays information on outside temperature,
compass direction and trip information.
Compass and Temperature Display This display provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is facing.
Trip Odometer (ODO) Shows the distance traveled since the last reset.
Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or
L/100 Km since the last reset.
Instant Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100 Km.
Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel
remaining in the tank. This is calibrated using the MPG for the last few minutes.
Elapsed Time (ET) Shows the accumulated ignition ON time since the last reset.
Step Button Press this button to cycle through all the mini-trip computer displays.
US/M Button Press this button to convert all vehicle displays from US to Metric to US.
To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds
and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,
ECO, ET) is currently being displayed.

Automatic Compass Calibration This compass is self calibrating which eliminates the need to
manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL
symbol will be displayed. After completing three 360' turns in an area free from large metal or
metallic objects, the CAL symbol will turn OFF and the compass will function normally.
Compass Variance Compass Variance is the difference between Magnetic North and Geographic
North. In some areas of the country, the difference between Magnetic and Geographic North is
great enough to cause the compass to give false readings. If this occurs, the compass variance
must be set.
To Set the Variance Turn the ignition ON and set display to Comp./Temp. while pressing the US/M
button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the
last variance zone number will be displayed. Press the US/Metric Button to select the proper
variance zone as shown on the map. Press the Step button to set the new variance zone and
resume normal operation.
ELECTRO/MECHANICAL INSTRUMENT CLUSTER (EMIC)
The Instrument Cluster contains a Fuel, Voltmeter, Coolant Temp, and Oil Pressure gauge, a
Tachometer and a Speedometer. With the exception of the Voltmeter, the cluster positions the
gauges with PCI Bus messages received from the PCM. The Voltmeter operates directly off of the
Fused B+ Switched Ignition Output circuit that supplies ignition voltage for the cluster.
The Instrument Cluster also contains warning indicators that are illuminated by hard wired inputs or
by messages received from other modules on the PCI Bus.
The Trip/Total Odometer is a Vacuum Fluorescent Display (VF) that is controlled by PCI Bus
messages received from the PCM.
The cluster illumination lamps are hard wired in the Instrument Cluster. When the Park or
Headlamps are turned ON, the cluster receives a dimmed battery feed from the Headlamp Switch.
The cluster I/O Processor controls the VF display dimming and also sends dimming level
messages on the PCI Bus.
The EMIC will communicate with the DRB III to display PCI Engine Info, PCI Bus Info, and certain
input/outputs. Cluster diagnostic capabilities that the DRB III will actuate are limited to the Cluster
Calibration Points for the gauges. The DRB III can also extract active and stored Diagnostic
Trouble Codes (DTC) from the Instrument Cluster.
The EMIC is also capable of performing a diagnostic Self-Test that is actuated by depressing and
holding the Odometer trip reset stalk while cycling the ignition from the OFF to the ON position.
After the cluster Odometer displays CHEC, releasing the reset stalk begins the test. The cluster will
then position all of the gauges at specified calibration points and will illuminate all the PCI Bus
controlled indicators. The cluster will also illuminate each segment of the VF display.
The EMIC can verify communications with the PCM, ID the module, or change the country code
using the DRB III.
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI
bus to the CTM module to unlock the doors. The interior lights will be turned ON when the vehicle
speed message on the PCI bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time
following the deployment. Once the ignition key has been cycled to the "OFF" position, normal
operation will resume.
EXTERIOR LIGHTING
The low and high beam headlamps are controlled directly by an output from the Central Timer
Module (CTM). The park lamps and fog lamps (on vehicle so equipped) are controlled via external
relays that are energized by the CTM. The headlamp switch provides the control signal through the
multifunction switch to the CTM, which indicates low or high beam operation.
The Optical Horn (Flash to Pass) feature operates both the high beam and low beam headlamps.
The CTM provides the Headlamp Time Delay feature. To start the delay, turn the ignition OFF
while the headlamps are ON. Then turn the headlamp switch to the OFF position. This has to be
done within 45 seconds of the ignition being turned OFF. The headlamps will remain ON for 60 ± 5
seconds. If during this delay period the headlamp switch is turned ON and then OFF, or ignition
switch is turned ON delay will be canceled and they will turn OFF immediately. During the delay
period, only headlamps are turned ON and park lamps/fog lamps are turned OFF.
The CTM also provides battery protection to avoid wearing down the battery if the customer leaves
the park lamps or headlamps ON for extended period of time with the ignition OFF. If the park
lamps or headlamps remain ON for more than 5 minutes while the ignition is OFF, the headlamps
and park lamps shall be turned off and the input causing the lamps to be ON will be ignored until
the input is corrected. Once the 5 minute timeout has extinguished the headlamps and park lamps,
any change in the ignition switch, door ajar switches, headlamps switch or park lamp switch will
reset the 5 minute timer and return the headlamps and park lamps to normal operation.

HEATING & A/C SYSTEM
The all-new heating and air conditioning system for DN provides more heating and cooling capacity
than in previous years. Depending on the model, either a Dual-Zone Air Conditioning System or a
Three-Zone Air Conditioning System is currently available in these vehicles.
Air Distribution (Front)
The front compartment HVAC unit has four fully adjustable instrument panel outlets. Side-window
demister outlets in the instrument panel eliminate the need for door ducts and door-to-instrument
panel seals. A single central mounted outlet delivers air for defrosting the windshield. Two outlets,
one on each side of the center console underneath the instrument panel, provide airflow to the
driver floor area and to the front seat passenger floor area. While two additional outlets, one on
each side of the center console near the rear of the front seats, distribute both heated and cooled
air across the floor to the intermediate seat passengers. Ducts in the center of the vehicle
underneath the carpet deliver air from the front compartment HVAC unit to the two intermediate
passenger outlets.
Door Actuator Control
A simplified control system for operation of the mode, recirculation, and temperature control
actuators provides positive positioning without the complexity of feedback from position sensors.
The A/C - Heater Control Module knows the number of operating actuator revolutions required for
full door travel as well as the number of actuator commutator pulses per revolution. Using these
parameters, the A/C - Heater Control Module runs the actuator for the number of commutator
pulses that correspond to the desired door position. To maintain accuracy, the system recalibrates
itself periodically at known zero and full travel conditions.
The dual sliding Blend switches have multiple detents to control the full range of temperature that
the system can produce in any mode. On Dual-Zone systems, the upper slide pot controls the
driver-side blend door and the lower slide pot controls the passenger-side blend door. On
Three-Zone systems, the upper slide pot controls the driver-side blend door, while the lower slide
pot controls the passenger-side blend door and the rear A/C - heater unit blend door.
The single rotary Mode switch has 12 detents to either direct airflow to the panel outlets, to a mix of
floor and panel outlets, to the floor outlets, to a mix of floor and defrost outlets, or to the defrost
outlet. Rotating the Mode switch to either of the two MAX positions results in the A/C - Heater
Control Module sending a signal to the recirculation actuator to close the fresh-air door. While
rotating the Mode switch to any other position results in the A/C - Heater Control Module sending a
signal to the recirculation actuator to open the fresh-air door.
When the Blower switch is OFF, the A/C - Heater Control Module closes the fresh-air door to
prevent outside air from entering the vehicle. On Three- Zone systems, the Mode switch also
controls the rear A/C - heater unit mode door, which directs rear airflow either to the right quarter
trim panel outlet or to the overhead outlets.
Front Blower Control
The front blower circuitry employs a new resistor technology to control front blower speed. Called
the "credit card" resistor, the device looks much like its name in that it is thin and compact like a
credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the
front HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card
resistor offers much less airflow restriction.
A/C Operation
The A/C - Heater Control Module monitors the temperature of the evaporator to keep it just above
freezing for maximum cooling and dehumidification. A thermistor (temperature variable resistor)
placed between the evaporator fins provides the signal for the control. The Powertrain Control
Module (PCM) cycles the compressor on and off with a signal from the A/C - Heater Control
Module.
Heater Operation
To assist the HVAC system in maintaining a consistent and optimum heat output at low vehicle
speeds, an electric coolant pump operates under specific conditions to keep a steady flow of hot
coolant circulating through the heater circuit. The A/C - Heater Control Modules controls the
operation of the electric coolant pump. The pump runs when all of the following conditions are met:
When the vehicle's speed is below 27 Km/h (17 mph), the coolant temperature is between 65.5 °C
and 110 °C (150 °F and 230 °F), and the blend control is set above 60% reheat. The A/C - Heater
Control Module turns the pump OFF if any one of the following conditions occur: The vehicle speed
rises above 48.3 Km/h (30 mph). The coolant temperature drops below 65.5 °C (150 °F). The
coolant temperature rises above 110 °C (230 °F). The blend control is set below 60% reheat.
A/C - Heater Control (Rear)
The Three-Zone system allows the intermediate seat occupants to regulate the air temperature and
the fan speed of the rear unit from the rotary controls on the headliner mounted Rear A/C - Heater
Control.
HVAC Diagnostics
The A/C - Heater Control Module is fully addressable with the DRB III. Two of the Control Module's
diagnostic capabilities that the DRB III will actuate include the A/C Cool down Test to test A/C
system performance and the HVAC Door Recalibration Test to determine actuator travel span.
After performing either test, the Control Module will display one or more messages on the DRB III
screen. The message will indicate either that the HVAC system passed the test or that there is a
fault currently active in the HVAC system. The DRB III can also extract active and stored
Diagnostic Trouble Codes (DTCs) from the control module. Active DTCs are faults that currently
exit in the HVAC system. Stored DTCs are faults that occurred in the HVAC system since the
control module received the last "clear diagnostic info" message.

The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module
(CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when
either the dome lamp switch is turned ON or a door is opened. The courtesy lamps will fade to OFF
immediately when all doors are closed with the dome lamp switch in the OFF position.
The illuminated entry feature operates under the following conditions: RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned ON
Once activated, the illuminated entry will "fade to OFF" after 3 to 5 seconds under the following
conditions: All doors are closed and: RKE "lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will not reset timer.
Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and
the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp
position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps.
The Interior lamp defeat feature will not allow any interior lamp to be turned ON. This is
accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps due to the following.
Leaving a door open, dome lamp switch ON, reading/vanity lamp switch ON or glove box door
open for more than 15 minutes while the ignition is OFF.
POWER DOOR LOCKS/REMOTE KEYLESS ENTRY
The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key
fob or interior switch.
Vehicles that are equipped with the Vehicle Theft Security System will also have the central locking
feature. With the central locking feature, when the cylinder lock switch is turned to the lock position
all the doors will lock. For unlocking, if the key is turned to the unlock position once, only that door
will unlock. If the key is then turned a second time to the unlock position, all the doors will unlock.
There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is
OFF and the key is in the ignition.
Automatic or "rolling locks" are included as a programmable feature. If the vehicle is moving
approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the
PCM will send this info to the CTM via the PCI bus) indicating acceleration, the CTM will cycle the
lock actuators to lock the doors.
The highline CTM provides for Remote Keyless Entry (RKE)
The RKE system is placed in the programming mode by the DRB III, or by the customer program
features. The system will store up to four key fob codes. Two fobs are supplied with the truck,
additional fobs may be purchased through the parts department. Through the DRB III, erasing and
programming of one key fob without deleting the others is possible. If the key fob is stolen, all the
fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense
of security.
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network
capable of supporting binary encoded messages shared between multiple modules. The PCI bus
circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added
to the yellow in order to distinguish between different module connections. The modules are wired
in parallel. Connections are made in the harness using a splice.
The splice called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit. The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 1952
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The
bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and
a half volts when modules are transmitting.
The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only
voltage present when the modules transmit and the message length is only about 500 milliseconds,
it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred
method is to use the DRB III lab scope. The 12v square wave selection on the 20-volt scale
provides a good view of the bus activity. Voltage on the bus should pulse between zero and about
seven and a half volts. Refer to the figure for some typical displays.
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 1953
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.
VEHICLE THEFT SECURITY SYSTEM
The VTSS system monitors the door ajar switches, and ignition switch to detect unauthorized entry
into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system
to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to
start the engine with a non-programmed SKIM key, it will start and stall. If the trigger condition is
still present, the lights will continue to flash for an additional 15 minutes, after which the system will
stop pulsing the lights and return to the "armed" state. The cause of the last 4 alarm triggers is
stored by the CTM and may be retrieved by the DRB III. The system may be disarmed by either an
unlock command from a valid RKE key fob by using a key in either door, or by using a valid SKIM
key in the ignition. The door key cylinders are equipped with disarm switches. There is also a VTSS
lamp on the dash that provides information to the driver about the state of the vehicle theft system.
WINDSHIELD WIPER SYSTEM
The DN truck is equipped with speed sensitive intermittent wipers. The low and high speeds are
controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by
the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as
selected by the driver, an immediate wipe of the windshield takes place and the new delay interval
is implemented.

Central Timer Module: Symptom Related Diagnostic Procedures
Non-Trouble Code Procedures
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module.
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING
FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
NOTE: The following tests may not prove conclusive in the diagnosis of the Central Timer Module
(CTM). The most reliable, efficient, and accurate means to diagnose the CTM requires the use of a
DRB III scan tool. Refer to the appropriate diagnostic information.
1. Check the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20 ampere) in the Power
Distribution Center (PDC). If OK, go to Step 2. If not
OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Check for battery voltage at the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20
ampere) in the PDC. If OK, go to Step 3. If not OK,
repair the open B(+) circuit between the PDC and the battery as required.

Central Timer Module: Component Tests and General Diagnostics
Road Testing A Complaint Vehicle
ROAD TEST WARNINGS
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: Before road testing a vehicle, be sure that all components are reassembled. During the
test drive, do not try to read the DRB III screen while in motion. Do not hang the DRB III from the
rear view mirror or operate it yourself. Have an assistant available to operate the DRB III.
Six Step Troubleshooting Procedure
SIX-STEP TROUBLESHOOTING PROCEDURE
Diagnosis is done in six basic steps:
1. Verification of complaint 2. Verification of any related symptoms 3. Symptom analysis 4. Problem
isolation 5. Repair of isolated problem 6. Verification of proper operation
Vehicle Preparation For Testing
VEHICLE PREPARATION FOR TESTING
Make sure the vehicle being tested has a fully charged battery. If it does not, false diagnostic codes
or error messages may occur.

Central Timer Module: Scan Tool Testing and Procedures
DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB III will display one of only two error messages:
User-Requested WARM Boot (Press MORE and NO at the same time)
User-Requested COLD Boot (Press MORE and YES at the same time)
If the DRB III should display any other error message, record the entire display and call the
S.T.A.R. Center for information and assistance.
DRB III DOES NOT POWER UP
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a
bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts
is required to adequately power the DRB III.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle
battery is fully charged, and inoperative DRB III may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate body diagnostics.
DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this
condition
SOME DISPLAY ITEMS READ "---"
This is caused by scrolling the DRB III display a single line up or down. The line which was scrolled
onto the screen might read "---". Use the Page

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component
Information > Diagrams > Diagram Information and Instructions > Page 2002
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component
Information > Diagrams > Diagram Information and Instructions > Page 2003
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.
Circuit Information

Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component
Information > Diagrams > Diagram Information and Instructions > Page 2004
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component
Information > Diagrams > Diagram Information and Instructions > Page 2005
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Powertrain Control Module: Description and Operation
Fig. 9 PCM Location
POWERTRAIN CONTROL MODULE
The Powertrain Control Module (PCM) is located in the engine compartment. The PCM is referred
to as JTEC.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed and the brake switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.
NOTE: PCM Inputs: A/C request (if equipped with factory A/C)
- A/C select (if equipped with factory A/C)

MODES OF OPERATION
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (O2S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (O2S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the O2S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation: Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Relays and Modules - Powertrain Management > Relays and
Modules - Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component
Information > Diagrams > Page 2028
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch ON, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
Ignition Switch (KEY-ON) Mode This is an Open Loop mode. When the fuel system is activated by
the ignition switch, the following actions occur: The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD relay. The 02S sensor input is not used
by the PCM to calibrate air-fuel ratio during this mode of operation.
Engine Start-Up Mode This is an Open Loop mode. The following actions occur when the starter
motor is engaged.The PCM receives inputs from: Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Starter motor relay
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
Engine Warm-Up Mode This is an Open Loop mode. During engine warmup, the PCM receives
inputs from: Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto.trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the clutch relay. This is done if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
Idle Mode When the engine is at operating temperature, this is a Closed Loop mode. At idle speed,
the PCM receives inputs from: Air conditioning select signal (if equipped)

Based on these inputs, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.It
also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Cruise Mode When the engine is at operating temperature, this is a Closed Loop mode. At cruising
speed, the PCM receives inputs from: Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (O2S) sensors
Based on these inputs, the following occurs: -
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control ('AC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Acceleration Mode This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle
position or MAP pressure as a demand for increased engine output and vehicle acceleration. The
PCM increases injector pulse width in response to increased throttle opening.
Deceleration Mode When the engine is at operating temperature, this is an Open Loop mode.
During hard deceleration, the PCM receives the following inputs. Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage

- Vehicle speed sensor
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor.

The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
Wide Open Throttle Mode This is an Open Loop mode. During wide open throttle operation, the
PCM receives the following inputs. Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
During wide open throttle conditions, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF. The PCM ignores the oxygen sensor input signal and provides a
predetermined amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
ignition switch OFF Mode When ignition switch is turned to OFF position, the PCM stops operating
the injectors, ignition coil, ASD relay and fuel pump relay.
5 VOLT SUPPLIES
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply: supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply: supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (if equipped with an RE
automatic transmission).
IGNITION CIRCUIT SENSE
This circuit ties the ignition switch to the Power- train Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage ON the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
POWER GROUND
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads: Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
SENSOR RETURN
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors. Refer
to Power Grounds for more information.
SIGNAL GROUND
Signal ground provides a low noise ground to the data link connector.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Fuel Level Sensor: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-ON,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Manifold Absolute Pressure (MAP) Sensor: Description and Operation
The MAP sensor is located on the front of the intake manifold. An O-ring seals the sensor to the
intake manifold.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-ON, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-ON (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor.
As the altitude increases, the air becomes thinner (less oxygen). If a vehicle is started and driven to
a very different altitude than where it was at key-ON, the barometric pressure needs to be updated.
Any time the PCM sees Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS)
angle and RPM, it will update barometric pressure in the MAP memory cell. With periodic updates,
the PCM can make its calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an object. At sea level on a standard
day, no storm, barometric pressure is approximately 29.92 in Hg. For every 100 feet of altitude,
barometric pressure drops 0.10 in. Hg. If a storm goes through it can change barometric pressure
from what should be present for that altitude. You should know what the average pressure and
corresponding barometric pressure is for your area.

Oxygen Sensor: Description and Operation
The Oxygen Sensors (O2S) are attached to, and protrude into the vehicle exhaust system.
Depending on the emission package, the vehicle may use a total of either 2 or 4 sensors.
NAA Emissions Package: Two sensors are used: upstream (referred to as 1/1) and downstream
(referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before
the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic
convertor.
NAS or NAE Emissions Package: On this emissions package, 4 sensors are used: 2 upstream
(referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission
package, the right upstream sensor (2/1) is located in the right exhaust downpipe just before the
mini-catalytic convertor. The left upstream sensor (1/1) is located in the left exhaust downpipe just
before the mini-catalytic convertor. The right downstream sensor (2/2) is located in the right
exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor.
The left downstream sensor (1/2) is located in the left exhaust downpipe just after the mini-catalytic
convertor, and before the main catalytic convertor.
An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely
proportional to the amount of oxygen in the exhaust. In other words, if the oxygen content is low,
the voltage output is high; if the oxygen content is high the output voltage is low. The PCM uses
this information to adjust injector pulse-width to achieve the 14.7-to-1 air/fuel ratio necessary for
proper engine operation and to control emissions.
The O2 sensor must have a source of oxygen from outside of the exhaust stream for comparison.
Current O2 sensors receive their fresh oxygen (outside air) supply through the wire harness. This is
why it is important to never solder an O2 sensor connector, or pack the connector with grease.
Four wires (circuits) are used on each O2 sensor: a 12-volt feed circuit for the sensor heating
element; a ground circuit for the heater element; a low-noise sensor return circuit to the PCM, and
an input circuit from the sensor back to the PCM to detect sensor operation.
Oxygen Sensor Heater Relay: If the vehicle is equipped with 4 oxygen sensors, a separate oxygen
sensor relay is used to supply voltage to the sensor heating elements. This particular relay is used
only for the 1/2 and 2/2 downstream sensors. Voltage for the other 2 sensor heating elements is
supplied directly from the ASD relay.
To avoid the large simultaneous current surge needed to operate all 4 sensors, power is delayed to
the 2 downstream heater elements by the PCM for approximately 2 seconds.
Oxygen Sensor Heater Elements: The O2 sensor uses a Positive Thermal Co-efficient (PTC)
heater element. As temperature increases, resistance increases. At ambient temperatures around
70 °F, the resistance of the heating element is approximately 13.5 ohms on the this engine. As the
sensor's temperature increases, resistance in the heater element increases. This allows the heater
to maintain the optimum operating temperature of approximately 930 ° - 1100 °F (500 ° - 600 °C).
Although the sensors operate the same, there are physical differences, due to the environment that
they operate in, that keep them from being interchangeable.
Maintaining correct sensor temperature at all times allows the system to enter into closed loop
operation sooner. Also, it allows the system to remain in closed loop operation during periods of
extended idle.
In Closed Loop operation, the PCM monitors certain O2 sensor input(s) along with other inputs,
and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the
O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values
and inputs from other sensors.
Upstream Sensor - Engine Equipped With 2 Sensors: The upstream sensor (1/1) provides an input
voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses
this information to fine tune fuel delivery to maintain the correct oxygen content at the downstream
oxygen sensor. The PCM will change the air/fuel ratio until the upstream sensor inputs a voltage
that the PCM has determined will make the downstream sensor output (oxygen content) correct.
The upstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Downstream Sensor - Engine Equipped With 2 Sensors: The downstream oxygen sensor (1/2) is
also used to determine the correct air-fuel ratio. As the oxygen content changes at the downstream
sensor, the PCM calculates how much air-fuel ratio change is required. The PCM then looks at the
upstream oxygen sensor voltage and changes fuel delivery until the upstream sensor voltage
changes enough to correct the downstream sensor voltage (oxygen content).
The downstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Upstream Sensors - Engine Equipped With 4 Sensors: Two upstream sensors are used (1/1 and
2/1). The 1/1 sensor is the first sensor to receive exhaust gases from the # 1 cylinder. They provide
an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The
PCM uses this information to fine tune fuel delivery to maintain the correct oxygen content at the
downstream oxygen sensors. The PCM will change the air/fuel ratio until the upstream sensors
input a voltage that the PCM has determined will make the downstream sensors output (oxygen
content) correct.
The upstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.

Switches - Computers and Control Systems > Oxygen Sensor > Component Information > Application and ID > Page 2146
Downstream Sensors - Engine Equipped With 4 Sensors: Two downstream sensors are used (1/2
and 2/2). The downstream sensors are used to determine the correct air-fuel ratio. As the oxygen
content changes at the downstream sensor, the PCM calculates how much air-fuel ratio change is
required. The PCM then looks at the upstream oxygen sensor voltage, and changes fuel delivery
until the upstream sensor voltage changes enough to correct the downstream sensor voltage
(oxygen content).
The downstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.
Engines equipped with either a downstream sensor(s), or a post-catalytic sensor, will monitor
catalytic convertor efficiency. If efficiency is below emission standards, the Malfunction Indicator
Lamp (MIL) will be illuminated and a Diagnostic Trouble Code (DTC) will be set. Refer to Monitored
Systems in Emission Control Systems for additional information.

REMOVAL
Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Spark Plug: Description and Operation
This engine are equipped with "fired in suppressor seal" type spark plugs using a copper core
ground electrode.
Because of the use of an aluminum cylinder head on this engine, spark plug torque is very critical.
To prevent possible pre-ignition and/or mechanical engine damage, the correct type/heat
range/number spark plug must be used.
Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken
porcelain insulators. Keep plugs arranged in the order in which they were removed from the
engine. A single plug displaying an abnormal condition indicates that a problem exists in the
corresponding cylinder. Replace spark plugs at the intervals recommended in Lubrication and
Maintenance.
Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or
oil fouled. Also refer to Spark Plug Conditions.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator and will cause plug misfire.

Spark Plug: Testing and Inspection
SPARK PLUG CONDITIONS
Fig. 20 Normal Operation And Cold (Carbon) Fouling
Normal Operating The few deposits present on the spark plug will probably be light tan or slightly
gray in color. This is evident with most grades of commercial gasoline. There will not be evidence
of electrode burning. On this engine gap growth will not average more than approximately 0.0015
in per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be
cleaned, have the electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a Manganese Additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits.
Cold Fouling/carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits
that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may
be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set
of spark plugs may be caused by a clogged air cleaner element or repeated short operating times
(short trips).
Wet Fouling Or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In
older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause
wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal
oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the
fouled plugs.

Fig. 21 Oil Or Ash Encrusted
Oil Or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine
condition for the cause of oil entry into that particular combustion chamber.
Fig. 22 Electrode Gap Bridging
Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion
chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving.
When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge
the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap
bridging can be cleaned using standard procedures.

Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug >
Component Information > Specifications > Page 2259
Fig. 23 Scavenger Deposits
Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to
be harmful, but this is a normal condition caused by chemical additives in certain fuses. These
additives are designed to change the chemical nature of deposits and decrease spark plug misfire
tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the
deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in
condition and can be cleaned using standard procedures.
Fig. 24 Chipped Electrode Insulator
Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center
electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation
can also separate the insulator from the center electrode. Spark plugs with this condition must be
replaced.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Tune-up and Engine Performance Checks > Spark Plug >
Component Information > Specifications > Page 2260
Fig. 25 Preignition Damage
Preignition Damage Preignition damage is usually caused by excessive combustion chamber
temperature. The center electrode dissolves first and the ground electrode dissolves somewhat
latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat
range rating for the engine. Determine if ignition timing is over advanced or if other operating
conditions are causing engine overheating. (The heat range rating refers to the operating
temperature of a particular type spark plug. Spark plugs are designed to operate within specific
temperature ranges. This depends upon the thickness and length of the center electrodes porcelain
insulator.)
Fig. 26 Spark Plug Overheating
Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that
also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch
per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be
used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause
spark plug overheating.

Spark Plug: Service and Repair
REMOVAL
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
In this engine: Each individual spark plug is located under each ignition coil. Each individual ignition
coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
1. In this engine: Prior to removing spark plug, spray compressed air around base of ignition coil at
cylinder head. This will help prevent foreign
material from entering combustion chamber.
2. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. If
equipped with this engine, also check condition of
coil O-ring and replace as necessary.
3. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
The plugs may be cleaned using commercially available spark plug cleaning equipment. After
cleaning, file center electrode flat with a small point file or jewelers file before adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean spark plugs. Metallic deposits will
remain on spark plug insulator and will cause plug misfire.
INSTALLATION
CAUTION: This engine is equipped with copper core ground electrode spark plugs. They must be
replaced with the same type/number spark plug as the original. If another spark plug is substituted,
pre-ignition will result.
Special care should be taken when installing spark plugs into the cylinder head spark plug wells.
Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. In this engine:
Tighten spark plugs to 27 Nm (20 ft. lbs.) torque. 3. In this engine: Before installing coil(s), check
condition of coil O-ring and replace as necessary. To aid in coil installation, apply silicone to coil
O-ring.
4. In this engine: Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

Intake Air Temperature (IAT) Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold with the
sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-ON,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Central Timer Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Central Timer Module: Vehicle Damage Warnings
Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could
damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of
the original problem more difficult,
Road Testing A Complaint Vehicle
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE
REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB III SCREEN
WHILE IN MOTION. DO NOT HANG THE DRB III FROM THE REAR VIEW MIRROR OR
OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB III.

Central Timer Module: Description and Operation Sytem Description
The body system on the 2001 DN consists of a combination of modules that communicate over the
PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus,
information about the operation of vehicle components and circuits is relayed quickly to the
appropriate module(s). All modules receive all the information transmitted on the bus even though
a module may not require all information to perform its function. It will only respond to messages
"addressed" to it through a binary coding process. This method of data transmission significantly
reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the
information about the functioning of all the systems is organized, controlled, and communicated by
the PCI bus, which is described in the vehicle communication of this general information.

Indicators / Audible Warning Device. See: Instrument Panel, Gauges and Warning
Indicators/Audible Warning Device
AIRBAG SYSTEM
The airbag system is designed to provide increased driver and passenger protection if the vehicle
is involved in a front end collision. The system is most effective when used in conjunction with the
seat belt system.
The Airbag Control Module (ACM) is an electronic module that monitors the airbag system for
proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and
contains the sensor and actuator that is responsible for airbag deployment. There are no external
impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck
at the bottom of the instrument panel. It is located forward of the console. The ACM provides
diagnostic information (DTCs) to the technician through the DRB III via the PCI bus. Some circuits
are tested continuously; others are checked only under certain circumstances. The warning lamp is
driven with messages relayed to the Electro/Mechanical Instrument Cluster (EMIC) from the ACM
via the PCI bus.
The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be
observed by the customer. Whenever the ignition key is turned to the "run" or "start" position, the
airbag control module performs a lamp check by turning the AIRBAG warning lamp ON for 6 - 8
seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to
be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the
system or the circuit that operates the lamp may be shorted to ground. If the lamp comes ON and
stays ON for a period longer than 6 - 8 seconds, then goes OFF, there is usually an intermittent
problem in the system.
WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT.
Seat Belt Tensioner
Front seat belt systems incorporate Tensioner Modules (SBT). At the onset of an impact event
each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to
rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact
will be reduced as will the likelihood of contacting interior components. After an impact that deploys
the airbag, the seat belt tensioner assembly must be replaced.
The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and
stored DTC's if any problem is found.
Airbag Diagnostic Trouble Codes
Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,
diagnostic priority should be given to the active codes.
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic
test procedures contain step-by-step instructions for determining the cause of the trouble codes. It
is not necessary to perform all of the tests in this book to diagnose an individual code.
Always begin by reading the diagnostic trouble codes using the DRB III.
Active diagnostic trouble codes for the airbag system are not permanent and will change the
moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes
are used as a diagnostic tool.
Active Codes
The code becomes active as soon as the malfunction is detected and stored after one minute of
occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going
malfunction. This means that the defect is currently there every time the airbag control module
checks that circuit/function. It is impossible to erase an active code; active codes automatically
erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is
detected, the airbag lamp remains lit for a minimum
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module <--> [Body
Control Module] > Component Information > Description and Operation > Sytem Description > Page 2326
of 12 seconds or as long as the malfunction is present.
Stored Codes
Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or
when the ignition is turned OFF. The exception is the "Loss of Ignition Run Only" code which is an
active code only.
A "stored" code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
When a trouble code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
The minimum time shown for any code will be one minute, even if the code was actually present for
less than one minute. Thus, the time shown for a code that was present for two minutes 13
seconds, for example, would be three minutes.
If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the
malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be
initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same
malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If
the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset
and the diagnostic trouble code will continue to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code
diagnostic test will not locate the source of the problem. In this case, the stored code can indicate
an area to inspect.
If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire
harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes
periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
AUDIO SYSTEM
The factory installed radio receiver communicates on the Programmable Communication Interface
(PCI) data bus network through a separate two-way wire harness connector. This is used for the
remote radio switches that are mounted to the steering wheel, and also used for radio diagnosis
with the DRB III.
The remote radio switches are resistor multiplexed units that are hard wired to the CTM through the
clockspring. The CTM monitors the status of the remote radio switches and sends the proper
switch status messages on the PCI data bus network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by
adjusting the radio settings as requested.
When troubleshooting output shorts or "output" error messages, the following applies: On radios
without an external amplifier, the term "output" refers to the path between the radio and the
speaker. This type of circuit can be monitored all the way through the speaker connections by the
radio assembly. When the radio displays a shorted output DTC with this type of system, the
speaker, radio or wiring could be at fault. The output DTC could refer to a front or rear output or a
left or right output. The reason for the difference is the pairing of the output sections of the radio.
Some are paired left and right, others are paired front and rear.
On radios with an external amplifier, the term "output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of monitoring only this portion and can tell nothing
about the circuit between the amplifier and the speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit. A faulty speaker could not cause this DTC.
CENTRAL TIMER MODULE
The Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or
Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.
The Base and Highline CTM provides the following features: Battery Saver Functions For Exterior and Interior Lamps
- Cargo Lamps
- Chime Warning
- Courtesy Lamps
- Dome Lamps
- Dome Defeat
- Door Ajar Switch Status
- Fog Lamps
- Head Lamp Time Delay
- Intermittent Wiper Controls
- Low and High Beam Head Lamps
- Optical Horn
- Park Lamps

The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
CHIME SYSTEM
The chime system is built into the CTM. There are two chime rates, Low: 50 chimes per minute for
reminders and High: 180 chimes per minute for serious conditions that require immediate attention.
The high rate chime sounds when the key is left in the ignition and the driver's door is open or if the
headlights or the courtesy lights are left on. The low rate chime sounds for any of the other
conditions. There is a variable rate feature that allows the chime to sound continuously for key-in
and headlamp warning as long as the door is open. The seat belt warning chime is activated for six
seconds, and all other chime conditions will activate the chime once at the same time the warning
light on the cluster is illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
COMPASS MINI-TRIP COMPUTER (CMTC)
This system, located in the overhead console, displays information on outside temperature,
compass direction and trip information.
Compass and Temperature Display This display provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is facing.
Trip Odometer (ODO) Shows the distance traveled since the last reset.
Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or
L/100 Km since the last reset.
Instant Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100 Km.
Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel
remaining in the tank. This is calibrated using the MPG for the last few minutes.
Elapsed Time (ET) Shows the accumulated ignition ON time since the last reset.
Step Button Press this button to cycle through all the mini-trip computer displays.
US/M Button Press this button to convert all vehicle displays from US to Metric to US.
To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds
and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,
ECO, ET) is currently being displayed.

Automatic Compass Calibration This compass is self calibrating which eliminates the need to
manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL
symbol will be displayed. After completing three 360' turns in an area free from large metal or
metallic objects, the CAL symbol will turn OFF and the compass will function normally.
Compass Variance Compass Variance is the difference between Magnetic North and Geographic
North. In some areas of the country, the difference between Magnetic and Geographic North is
great enough to cause the compass to give false readings. If this occurs, the compass variance
must be set.
To Set the Variance Turn the ignition ON and set display to Comp./Temp. while pressing the US/M
button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the
last variance zone number will be displayed. Press the US/Metric Button to select the proper
variance zone as shown on the map. Press the Step button to set the new variance zone and
resume normal operation.
ELECTRO/MECHANICAL INSTRUMENT CLUSTER (EMIC)
The Instrument Cluster contains a Fuel, Voltmeter, Coolant Temp, and Oil Pressure gauge, a
Tachometer and a Speedometer. With the exception of the Voltmeter, the cluster positions the
gauges with PCI Bus messages received from the PCM. The Voltmeter operates directly off of the
Fused B+ Switched Ignition Output circuit that supplies ignition voltage for the cluster.
The Instrument Cluster also contains warning indicators that are illuminated by hard wired inputs or
by messages received from other modules on the PCI Bus.
The Trip/Total Odometer is a Vacuum Fluorescent Display (VF) that is controlled by PCI Bus
messages received from the PCM.
The cluster illumination lamps are hard wired in the Instrument Cluster. When the Park or
Headlamps are turned ON, the cluster receives a dimmed battery feed from the Headlamp Switch.
The cluster I/O Processor controls the VF display dimming and also sends dimming level
messages on the PCI Bus.
The EMIC will communicate with the DRB III to display PCI Engine Info, PCI Bus Info, and certain
input/outputs. Cluster diagnostic capabilities that the DRB III will actuate are limited to the Cluster
Calibration Points for the gauges. The DRB III can also extract active and stored Diagnostic
Trouble Codes (DTC) from the Instrument Cluster.
The EMIC is also capable of performing a diagnostic Self-Test that is actuated by depressing and
holding the Odometer trip reset stalk while cycling the ignition from the OFF to the ON position.
After the cluster Odometer displays CHEC, releasing the reset stalk begins the test. The cluster will
then position all of the gauges at specified calibration points and will illuminate all the PCI Bus
controlled indicators. The cluster will also illuminate each segment of the VF display.
The EMIC can verify communications with the PCM, ID the module, or change the country code
using the DRB III.
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI
bus to the CTM module to unlock the doors. The interior lights will be turned ON when the vehicle
speed message on the PCI bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time
following the deployment. Once the ignition key has been cycled to the "OFF" position, normal
operation will resume.
EXTERIOR LIGHTING
The low and high beam headlamps are controlled directly by an output from the Central Timer
Module (CTM). The park lamps and fog lamps (on vehicle so equipped) are controlled via external
relays that are energized by the CTM. The headlamp switch provides the control signal through the
multifunction switch to the CTM, which indicates low or high beam operation.
The Optical Horn (Flash to Pass) feature operates both the high beam and low beam headlamps.
The CTM provides the Headlamp Time Delay feature. To start the delay, turn the ignition OFF
while the headlamps are ON. Then turn the headlamp switch to the OFF position. This has to be
done within 45 seconds of the ignition being turned OFF. The headlamps will remain ON for 60 ± 5
seconds. If during this delay period the headlamp switch is turned ON and then OFF, or ignition
switch is turned ON delay will be canceled and they will turn OFF immediately. During the delay
period, only headlamps are turned ON and park lamps/fog lamps are turned OFF.
The CTM also provides battery protection to avoid wearing down the battery if the customer leaves
the park lamps or headlamps ON for extended period of time with the ignition OFF. If the park
lamps or headlamps remain ON for more than 5 minutes while the ignition is OFF, the headlamps
and park lamps shall be turned off and the input causing the lamps to be ON will be ignored until
the input is corrected. Once the 5 minute timeout has extinguished the headlamps and park lamps,
any change in the ignition switch, door ajar switches, headlamps switch or park lamp switch will
reset the 5 minute timer and return the headlamps and park lamps to normal operation.

HEATING & A/C SYSTEM
The all-new heating and air conditioning system for DN provides more heating and cooling capacity
than in previous years. Depending on the model, either a Dual-Zone Air Conditioning System or a
Three-Zone Air Conditioning System is currently available in these vehicles.
Air Distribution (Front)
The front compartment HVAC unit has four fully adjustable instrument panel outlets. Side-window
demister outlets in the instrument panel eliminate the need for door ducts and door-to-instrument
panel seals. A single central mounted outlet delivers air for defrosting the windshield. Two outlets,
one on each side of the center console underneath the instrument panel, provide airflow to the
driver floor area and to the front seat passenger floor area. While two additional outlets, one on
each side of the center console near the rear of the front seats, distribute both heated and cooled
air across the floor to the intermediate seat passengers. Ducts in the center of the vehicle
underneath the carpet deliver air from the front compartment HVAC unit to the two intermediate
passenger outlets.
Door Actuator Control
A simplified control system for operation of the mode, recirculation, and temperature control
actuators provides positive positioning without the complexity of feedback from position sensors.
The A/C - Heater Control Module knows the number of operating actuator revolutions required for
full door travel as well as the number of actuator commutator pulses per revolution. Using these
parameters, the A/C - Heater Control Module runs the actuator for the number of commutator
pulses that correspond to the desired door position. To maintain accuracy, the system recalibrates
itself periodically at known zero and full travel conditions.
The dual sliding Blend switches have multiple detents to control the full range of temperature that
the system can produce in any mode. On Dual-Zone systems, the upper slide pot controls the
driver-side blend door and the lower slide pot controls the passenger-side blend door. On
Three-Zone systems, the upper slide pot controls the driver-side blend door, while the lower slide
pot controls the passenger-side blend door and the rear A/C - heater unit blend door.
The single rotary Mode switch has 12 detents to either direct airflow to the panel outlets, to a mix of
floor and panel outlets, to the floor outlets, to a mix of floor and defrost outlets, or to the defrost
outlet. Rotating the Mode switch to either of the two MAX positions results in the A/C - Heater
Control Module sending a signal to the recirculation actuator to close the fresh-air door. While
rotating the Mode switch to any other position results in the A/C - Heater Control Module sending a
signal to the recirculation actuator to open the fresh-air door.
When the Blower switch is OFF, the A/C - Heater Control Module closes the fresh-air door to
prevent outside air from entering the vehicle. On Three- Zone systems, the Mode switch also
controls the rear A/C - heater unit mode door, which directs rear airflow either to the right quarter
trim panel outlet or to the overhead outlets.
Front Blower Control
The front blower circuitry employs a new resistor technology to control front blower speed. Called
the "credit card" resistor, the device looks much like its name in that it is thin and compact like a
credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the
front HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card
resistor offers much less airflow restriction.
A/C Operation
The A/C - Heater Control Module monitors the temperature of the evaporator to keep it just above
freezing for maximum cooling and dehumidification. A thermistor (temperature variable resistor)
placed between the evaporator fins provides the signal for the control. The Powertrain Control
Module (PCM) cycles the compressor on and off with a signal from the A/C - Heater Control
Module.
Heater Operation
To assist the HVAC system in maintaining a consistent and optimum heat output at low vehicle
speeds, an electric coolant pump operates under specific conditions to keep a steady flow of hot
coolant circulating through the heater circuit. The A/C - Heater Control Modules controls the
operation of the electric coolant pump. The pump runs when all of the following conditions are met:
When the vehicle's speed is below 27 Km/h (17 mph), the coolant temperature is between 65.5 °C
and 110 °C (150 °F and 230 °F), and the blend control is set above 60% reheat. The A/C - Heater
Control Module turns the pump OFF if any one of the following conditions occur: The vehicle speed
rises above 48.3 Km/h (30 mph). The coolant temperature drops below 65.5 °C (150 °F). The
coolant temperature rises above 110 °C (230 °F). The blend control is set below 60% reheat.
A/C - Heater Control (Rear)
The Three-Zone system allows the intermediate seat occupants to regulate the air temperature and
the fan speed of the rear unit from the rotary controls on the headliner mounted Rear A/C - Heater
Control.
HVAC Diagnostics
The A/C - Heater Control Module is fully addressable with the DRB III. Two of the Control Module's
diagnostic capabilities that the DRB III will actuate include the A/C Cool down Test to test A/C
system performance and the HVAC Door Recalibration Test to determine actuator travel span.
After performing either test, the Control Module will display one or more messages on the DRB III
screen. The message will indicate either that the HVAC system passed the test or that there is a
fault currently active in the HVAC system. The DRB III can also extract active and stored
Diagnostic Trouble Codes (DTCs) from the control module. Active DTCs are faults that currently
exit in the HVAC system. Stored DTCs are faults that occurred in the HVAC system since the
control module received the last "clear diagnostic info" message.
INTERIOR LIGHTING

Control Module] > Component Information > Description and Operation > Sytem Description > Page 2330
The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module
(CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when
either the dome lamp switch is turned ON or a door is opened. The courtesy lamps will fade to OFF
immediately when all doors are closed with the dome lamp switch in the OFF position.
The illuminated entry feature operates under the following conditions: RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned ON
Once activated, the illuminated entry will "fade to OFF" after 3 to 5 seconds under the following
conditions: All doors are closed and: RKE "lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will not reset timer.
Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and
the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp
position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps.
The Interior lamp defeat feature will not allow any interior lamp to be turned ON. This is
accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps due to the following.
Leaving a door open, dome lamp switch ON, reading/vanity lamp switch ON or glove box door
open for more than 15 minutes while the ignition is OFF.
POWER DOOR LOCKS/REMOTE KEYLESS ENTRY
The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key
fob or interior switch.
Vehicles that are equipped with the Vehicle Theft Security System will also have the central locking
feature. With the central locking feature, when the cylinder lock switch is turned to the lock position
all the doors will lock. For unlocking, if the key is turned to the unlock position once, only that door
will unlock. If the key is then turned a second time to the unlock position, all the doors will unlock.
There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is
OFF and the key is in the ignition.
Automatic or "rolling locks" are included as a programmable feature. If the vehicle is moving
approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the
PCM will send this info to the CTM via the PCI bus) indicating acceleration, the CTM will cycle the
lock actuators to lock the doors.
The highline CTM provides for Remote Keyless Entry (RKE)
The RKE system is placed in the programming mode by the DRB III, or by the customer program
features. The system will store up to four key fob codes. Two fobs are supplied with the truck,
additional fobs may be purchased through the parts department. Through the DRB III, erasing and
programming of one key fob without deleting the others is possible. If the key fob is stolen, all the
fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense
of security.
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network
capable of supporting binary encoded messages shared between multiple modules. The PCI bus
circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added
to the yellow in order to distinguish between different module connections. The modules are wired
in parallel. Connections are made in the harness using a splice.
The splice called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit. The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module <--> [Body
Control Module] > Component Information > Description and Operation > Sytem Description > Page 2331
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The
bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and
a half volts when modules are transmitting.
The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only
voltage present when the modules transmit and the message length is only about 500 milliseconds,
it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred
method is to use the DRB III lab scope. The 12v square wave selection on the 20-volt scale
provides a good view of the bus activity. Voltage on the bus should pulse between zero and about
seven and a half volts. Refer to the figure for some typical displays.
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Central Timer Module <--> [Body
Control Module] > Component Information > Description and Operation > Sytem Description > Page 2332
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.
VEHICLE THEFT SECURITY SYSTEM
The VTSS system monitors the door ajar switches, and ignition switch to detect unauthorized entry
into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system
to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to
start the engine with a non-programmed SKIM key, it will start and stall. If the trigger condition is
still present, the lights will continue to flash for an additional 15 minutes, after which the system will
stop pulsing the lights and return to the "armed" state. The cause of the last 4 alarm triggers is
stored by the CTM and may be retrieved by the DRB III. The system may be disarmed by either an
unlock command from a valid RKE key fob by using a key in either door, or by using a valid SKIM
key in the ignition. The door key cylinders are equipped with disarm switches. There is also a VTSS
lamp on the dash that provides information to the driver about the state of the vehicle theft system.
WINDSHIELD WIPER SYSTEM
The DN truck is equipped with speed sensitive intermittent wipers. The low and high speeds are
controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by
the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as
selected by the driver, an immediate wipe of the windshield takes place and the new delay interval
is implemented.

Central Timer Module: Symptom Related Diagnostic Procedures
Non-Trouble Code Procedures
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module.
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING
FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
NOTE: The following tests may not prove conclusive in the diagnosis of the Central Timer Module
(CTM). The most reliable, efficient, and accurate means to diagnose the CTM requires the use of a
DRB III scan tool. Refer to the appropriate diagnostic information.
1. Check the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20 ampere) in the Power
Distribution Center (PDC). If OK, go to Step 2. If not
OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Check for battery voltage at the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20
ampere) in the PDC. If OK, go to Step 3. If not OK,
repair the open B(+) circuit between the PDC and the battery as required.
3. Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness
connector (Connector C3) for the CTM from the
CTM connector receptacle. Reconnect the battery negative cable. Check for battery voltage at
each of the two fused B(+) circuit cavities of the instrument panel wire harness connector
(Connector C3) for the CTM. If OK, disconnect and isolate the battery negative cable, reconnect
the instrument panel wire harness connector (Connector C3) for the CTM to the CTM connector
receptacle, and go to Step 4. If not OK, repair the open fused B(+) circuit(s) between the CTM and
the PDC as required.
4. Check the fused ignition switch output (run-start) fuse (Fuse 11 - 10 ampere) and the fused
ignition switch output (run-acc) fuse (Fuse 5 - 20
ampere) in the Junction Block (JB). If OK, go to Step 5. If not OK, repair the shorted circuit or

DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB III will display one of only two error messages:
User-Requested WARM Boot (Press MORE and NO at the same time)
User-Requested COLD Boot (Press MORE and YES at the same time)
If the DRB III should display any other error message, record the entire display and call the
S.T.A.R. Center for information and assistance.
DRB III DOES NOT POWER UP
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a
bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts
is required to adequately power the DRB III.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle
battery is fully charged, and inoperative DRB III may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate body diagnostics.
DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this
condition
SOME DISPLAY ITEMS READ "---"
This is caused by scrolling the DRB III display a single line up or down. The line which was scrolled
onto the screen might read "---". Use the Page

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Data Link Connector: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation
Troubleshooting Tests
Fig.6 Electrostatic Discharge Symbol
STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES
All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When
handling any component with this symbol, comply with the following procedures to reduce the
possibility of electrostatic charge build up on the body and inadvertent discharge into the
component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.

Fig.7 Testing For Voltage Potential
STANDARD PROCEDURE - TESTING FOR VOLTAGE POTENTIAL
1. Connect the ground lead of a voltmeter to a known good ground (Fig. 7). 2. Connect the other
lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to
check voltage. Refer to the
appropriate test procedure.
STANDARD PROCEDURE - TESTING FOR CONTINUITY
1. Remove the fuse for the circuit being checked or, disconnect the battery.
Fig.8 Testing For Continuity
2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8). 3. Connect the
other lead to the other end of the circuit being tested. Low or no resistance means good continuity.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND
1. Remove the fuse and disconnect all items involved with the fuse. 2. Connect a test light or a
voltmeter across the terminals of the fuse. 3. Starting at the fuse block, wiggle the wiring harness
about 6 - 8 inches apart and watch the voltmeter/test lamp.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Data Link Connector >
Component Information > Diagrams > Diagram Information and Instructions > Page 2393
4. If the voltmeter registers voltage or the test lamp glows, there is a short to ground in that general
area of the wiring harness.
STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING
SEVERAL LOADS
1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.
2. Replace the blown fuse. 3. Supply power to the fuse by turning ON the ignition switch or
re-connecting the battery. 4. Start connecting or energizing the items in the fuse circuit one at a
time. When the fuse blows the circuit with the short to ground has been isolated.
Fig.9 Testing For Voltage Drop
STANDARD PROCEDURE - TESTING FOR A VOLTAGE DROP
1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <-->
[Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2433
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <-->
[Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2434
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.
Circuit Information

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <-->
[Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2435
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <-->
[Engine Control Module] > Component Information > Diagrams > Diagram Information and Instructions > Page 2436
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Powertrain Control Module: Description and Operation
Fig. 9 PCM Location
POWERTRAIN CONTROL MODULE
The Powertrain Control Module (PCM) is located in the engine compartment. The PCM is referred
to as JTEC.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed and the brake switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.
NOTE: PCM Inputs: A/C request (if equipped with factory A/C)
- A/C select (if equipped with factory A/C)
- Auto shutdown (ASD) sense

MODES OF OPERATION
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (O2S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (O2S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the O2S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation: Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Powertrain Control Module <-->
[Engine Control Module] > Component Information > Diagrams > Page 2459
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch ON, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
Ignition Switch (KEY-ON) Mode This is an Open Loop mode. When the fuel system is activated by
the ignition switch, the following actions occur: The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD relay. The 02S sensor input is not used
by the PCM to calibrate air-fuel ratio during this mode of operation.
Engine Start-Up Mode This is an Open Loop mode. The following actions occur when the starter
motor is engaged.The PCM receives inputs from: Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Starter motor relay
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
Engine Warm-Up Mode This is an Open Loop mode. During engine warmup, the PCM receives
inputs from: Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto.trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the clutch relay. This is done if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
Idle Mode When the engine is at operating temperature, this is a Closed Loop mode. At idle speed,
the PCM receives inputs from: Air conditioning select signal (if equipped)

[Engine Control Module] > Component Information > Diagrams > Page 2460
- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors
Based on these inputs, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.It
also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Cruise Mode When the engine is at operating temperature, this is a Closed Loop mode. At cruising
speed, the PCM receives inputs from: Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (O2S) sensors
Based on these inputs, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control ('AC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Acceleration Mode This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle
position or MAP pressure as a demand for increased engine output and vehicle acceleration. The
PCM increases injector pulse width in response to increased throttle opening.
Deceleration Mode When the engine is at operating temperature, this is an Open Loop mode.
During hard deceleration, the PCM receives the following inputs. Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed sensor
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor.

PCM receives the following inputs. Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
During wide open throttle conditions, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF. The PCM ignores the oxygen sensor input signal and provides a
predetermined amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
ignition switch OFF Mode When ignition switch is turned to OFF position, the PCM stops operating
the injectors, ignition coil, ASD relay and fuel pump relay.
5 VOLT SUPPLIES
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply: supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply: supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (if equipped with an RE
automatic transmission).
IGNITION CIRCUIT SENSE
This circuit ties the ignition switch to the Power- train Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage ON the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
POWER GROUND
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads: Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
SENSOR RETURN
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors. Refer
to Power Grounds for more information.
SIGNAL GROUND
Signal ground provides a low noise ground to the data link connector.

The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Idle Air Control (IAC) Motor: Description and Operation
The IAC stepper motor is mounted to the throttle body, and regulates the amount of air bypassing
the control of the throttle plate. As engine loads and ambient temperatures change, engine rpm
changes. A pintle on the IAC stepper motor protrudes into a passage in the throttle body,
controlling air flow through the passage. The IAC is controlled by the Powertrain Control Module
(PCM) to maintain the target engine idle speed.
At idle, engine speed can be increased by retracting the IAC motor pintle and allowing more air to
pass through the port, or it can be decreased by restricting the passage with the pintle and
diminishing the amount of air bypassing the throttle plate.
The IAC is called a stepper motor because it is moved (rotated) in steps, or increments. Opening
the IAC opens an air passage around the throttle blade which increases RPM.
The PCM uses the IAC motor to control idle speed (along with timing) and to reach a desired MAP
during decel (keep engine from stalling).
The IAC motor has 4 wires with 4 circuits. Two of the wires are for 12 volts and ground to supply
electrical current to the motor windings to operate the stepper motor in one direction. The other 2
wires are also for 12 volts and ground to supply electrical current to operate the stepper motor in
the opposite direction.
To make the IAC go in the opposite direction, the PCM just reverses polarity on both windings. If
only 1 wire is open, the IAC can only be moved 1 step (increment) in either direction. To keep the
IAC motor in position when no movement is needed, the PCM will energize both windings at the
same time. This locks the IAC motor in place.
In the IAC motor system, the PCM will count every step that the motor is moved. This allows the
PCM to determine the motor pintle position. If the memory is cleared, the PCM no longer knows the
position of the pintle. So at the first key ON, the PCM drives the IAC motor closed, regardless of
where it was before. This zeros the counter, From this point the PCM will back out the IAC motor
and keep track of its position again.
When engine rpm is above idle speed, the IAC is used for the following:
- OFF-idle dashpot (throttle blade will close quickly but idle speed will not stop quickly)
- Deceleration air flow control
- A/C compressor load control (also opens the passage slightly before the compressor is engaged
so that the engine rpm does not dip down when the compressor engages)
- Power steering load control
The PCM can control polarity of the circuit to control direction of the stepper motor.
IAC Stepper Motor Program: The PCM is also equipped with a memory program that records the
number of steps the IAC stepper motor most recently advanced to during a certain set of
parameters. For example: The PCM was attempting to maintain a 1000 rpm target during a cold
start-up cycle. The last recorded number of steps for that may have been 125. That value would be
recorded in the memory cell so that the next time the PCM recognizes the identical conditions, the
PCM recalls that 125 steps were required to maintain the target. This program allows for greater
customer satisfaction due to greater control of engine idle.
Another function of the memory program, which occurs when the power steering switch (if
equipped), or the A/C request circuit, requires that the IAC stepper motor control engine rpm, is the
recording of the last targeted steps into the memory cell. The PCM can anticipate A/C compressor
loads. This is accomplished by delaying compressor operation for approximately 0.5 seconds until
the PCM moves the IAC stepper motor to the recorded steps that were loaded into the memory
cell. Using this program helps eliminate idle-quality changes as loads change. Finally, the PCM
incorporates a "No-Load" engine speed limiter of approximately 1800 - 2000 rpm, when it
recognizes that the TPS is indicating an idle signal and IAC motor cannot maintain engine idle.
A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle
plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are
controlled by the IAC motor through the PCM.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Information Bus: Description and Operation
PROGRAMMABLE COMMUNICATION INTERFACE (PCI)
The Programmable Communication Interface (PCI) data bus system is a single wire multiplexed
network used for vehicle communications. Multiplexing is a system that enables the transmission of
binary encoded messages over a single channel or circuit between multiple modules. All
DaimlerChrysler vehicles use this principle for communication between various
microprocessor-based electronic control modules. The PCI bus circuit is identified as D25 and is
yellow with a violet tracer, or violet with a yellow tracer, depending upon the application. Additional
tracer colors may be added to the violet in order to distinguish between different module
connections. The modules are wired in parallel. Connections are made in the harness using
splices.
Diagnostic Junction Port
One splice, called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit.
The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
The PCI data bus exceeds the Society of Automotive Engineers (SAE) J1850 Standard for Class B
Multiplexing.
Many of the electronic control modules in a vehicle require information from the same sensing
device. In the past, if information from one sensing device was required by several controllers, a
wire from each controller needed to be connected in parallel to that sensor. In addition, each
controller utilizing analog sensors required an Analog/Digital (A/D) converter in order to "read"
these sensor inputs. Multiplexing reduces wire harness complexity, sensor current loads and
controller hardware because each sensing device is connected to only one controller, which reads
and distributes the sensor information to the other controllers over the data bus. Also, because
each controller on the data bus can access the controller sensor inputs to every other controller on
the data bus, more function and feature capabilities are possible.
In addition to reducing wire harness complexity, component sensor current loads and controller
hardware, multiplexing offers a diagnostic advantage. A multiplex system allows the information
flowing between controllers to be monitored using a diagnostic scan tool. The DaimlerChrysler
system allows an electronic control module to broadcast message data out onto the bus where all
other electronic control modules can "hear" the messages that are being sent. When a module
hears a message on the data bus that it requires, it relays that message to its micro-processor.
Each module ignores the messages on the data bus that are being sent to other electronic control
modules.

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component
Information > Diagrams > Page 2504
The PCI data bus messages are carried over the bus in the form of Variable Pulse Width
Modulated (VPWM) signals. The PCI data bus speed is an average 10.8 Kilo-bits per second
(Kbps). By comparison, the prior two-wire Chrysler Collision Detection (CCD) data bus system is
designed to run at 7.8125 Kbps. Since there is only voltage present when the modules transmit and
the message length is only about 500 milliseconds, it is ineffective to try and measure the bus
activity with a conventional voltmeter. The preferred method is to use DRB III lab scope. The 12 V
square wave selection on the 20-volt scale provides a good view of the bus activity. Voltage on the
bus should pulse between zero and about 7-1/2 volts. Refer to the figure for some typical displays.
The voltage network used to transmit messages requires biasing and termination. Each module on
the PCI data bus system provides its own biasing and termination in order to transmit and receive
messages. Each module (also referred to as a node) terminates the bus through a terminating
resistor and a terminating capacitor. There are two types of nodes on the bus. The dominant node
terminates the bus through a 1 KW resistor and a 3300 pF capacitor. The Powertrain Control
Module (PCM) is the only dominant node for the PCI data bus system. A standard node terminates
the bus through an 11 KW resistor and a 330 pF capacitor.
The modules bias the bus when transmitting a message. The PCI bus uses low and high voltage
levels to generate signals. Low voltage is around 0 volts and the high voltage is about 7-1/2 volts.
The low and high voltage levels are generated by means of variable-pulse width modulation to form
signals of varying length. The Variable Pulse Width Modulation (VPWM) used in PCI bus
messaging is a method in which both the state of the bus and the width of the pulse are used to
encode bit information. A "zero" bit is defined as a short low pulse or a long high pulse. A "one" bit
is defined as a long low pulse or a short high pulse. A low (passive) state on the bus does not
necessarily mean a zero bit.
It also depends upon pulse width. If the width is short, it stands for a zero bit. If the width is long, it
stands for a one bit. Similarly, a high (active) state does not necessarily mean a one bit. This too
depends upon pulse width. If the width is short, it stands for a one bit. If the width is long, it stands
for a zero bit.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Information Bus > Component
Information > Diagrams > Page 2505
In the case where there are successive zero or one data bits, both the state of the bus and the
width of the pulse are changed alternately. This encoding scheme is used for two reasons. First,
this ensures that only one symbol per transition and one transition per symbol exists. On each
transition, every transmitting module must decode the symbol on the bus and begin timing of the
next symbol. Since timing of the next symbol begins with the last transition detected on the bus, all
of the modules are re-synchronized with each symbol. This ensures that there are no accumulated
timing errors during PCI data bus communication.
The second reason for this encoding scheme is to guarantee that the zero bit is the dominant bit on
the bus. When two modules are transmitting simultaneously on the bus, there must be some form
of arbitration to determine which module will gain control. A data collision occurs when two
modules are transmitting different messages at the same time. When a module is transmitting on
the bus, it is reading the bus at the same time to ensure message integrity. When a collision is
detected, the module that transmitted the one bit stops sending messages over the bus until the
bus becomes idle.
Each module is capable of transmitting and receiving data simultaneously. The typical PCI bus
message has the following four components:
- Message Header - One to three bytes in length. The header contains information identifying the
message type and length, message priority, target module(s) and sending module.
- Data Byte(s) - This is the actual message that is being sent.
- Cyclic Redundancy Check (CRC) Byte - This byte is used to detect errors during a message
transmission.
- In-Frame Response (IFR) byte(s) - If a response is required from the target module(s), it can be
sent during this frame. This function is described in greater detail in the following paragraph.
The IFR consists of one or more bytes, which are transmitted during a message. If the sending
module requires information to be received immediately, the target module(s) can send data over
the bus during the original message. This allows the sending module to receive time-critical
information without having to wait for the target module to access the bus. After the IFR is received,
the sending module broadcasts an End Of Frame (EOF) message and releases control of the bus.
The PCI data bus can be monitored using the DRB III scan tool. It is possible, however, for the bus
to pass all DRB III tests and still be faulty if the voltage parameters are all within the specified
range and false messages are being sent.
PCI Bus Failure Modes
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. The MIL is
located in the Information Center area of the instrument cluster overlay, to the left of center. The
MIL consists of a stencilled cutout of the International Control and Display Symbol icon for "Engine"
in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents
the indicator from being clearly visible when it is not illuminated. An amber lens behind the cutout in
the opaque layer of the overlay causes the icon to appear in amber through the translucent outer
layer of the overlay when the indicator is illuminated from behind by a Light Emitting Diode (LED)
soldered onto the instrument cluster electronic circuit board. The MIL is serviced as a unit with the
instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) has recorded a Diagnostic Trouble Code (DTC) for an On-Board
Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is controlled by
a transistor on the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the PCM over the Programmable Communications Interface
(PCI) data bus. The MIL Light Emitting Diode (LED) receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the ON or Start positions; therefore, the LED will always be OFF when the
ignition switch is in any position except ON or Start. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn ON the MIL for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the indicator is illuminated
for about seven seconds as a bulb test.
- PCM Lamp-ON Message - Each time the cluster receives a lamp-on message from the PCM, the
indicator will be illuminated. The indicator can be flashed ON and OFF, or illuminated solid, as
dictated by the PCM message. For some DTC's, if a problem does not recur, the PCM will send a
lamp-off message automatically. Other DTC's may require that a fault be repaired and the PCM be
reset before a lamp-OFF message will be sent. For more information on the PCM, and the DTC set
and reset parameters, (Refer to EMISSIONS CONTROL - OPERATION).
- Communication Error - If the cluster receives no lamp-on message from the PCM for twenty
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid lamp-ON message is
received from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON during the bulb check portion of the test to confirm the functionality of the LED and the cluster
control circuitry.
The PCM continually monitors the fuel and emissions system circuits and sensors to decide
whether the system is in good operating condition. The PCM then sends the proper lamp-ON or
lamp-OFF messages to the instrument cluster. If the instrument cluster turns ON the MIL after the
bulb test, it may indicate that a malfunction has occurred and that the fuel and emissions systems
may require service. For proper diagnosis of the fuel and emissions systems, the PCM, the PCI
data bus, or the message inputs to the instrument cluster that control the MIL, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.

Manifold Absolute Pressure (MAP) Sensor: Description and Operation
The MAP sensor is located on the front of the intake manifold. An O-ring seals the sensor to the
intake manifold.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-ON, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-ON (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor.
As the altitude increases, the air becomes thinner (less oxygen). If a vehicle is started and driven to
a very different altitude than where it was at key-ON, the barometric pressure needs to be updated.
Any time the PCM sees Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS)
angle and RPM, it will update barometric pressure in the MAP memory cell. With periodic updates,
the PCM can make its calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an object. At sea level on a standard
day, no storm, barometric pressure is approximately 29.92 in Hg. For every 100 feet of altitude,
barometric pressure drops 0.10 in. Hg. If a storm goes through it can change barometric pressure
from what should be present for that altitude. You should know what the average pressure and
corresponding barometric pressure is for your area.

This signal is then transferred (bussed) to the instrument panel on a CCD bus circuit to operate the
oil pressure gauge and the check gauges lamp. Ground for the sensor is provided by the PCM
through a low noise sensor return.

Oxygen Sensor: Description and Operation
The Oxygen Sensors (O2S) are attached to, and protrude into the vehicle exhaust system.
Depending on the emission package, the vehicle may use a total of either 2 or 4 sensors.
NAA Emissions Package: Two sensors are used: upstream (referred to as 1/1) and downstream
(referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before
the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic
convertor.
NAS or NAE Emissions Package: On this emissions package, 4 sensors are used: 2 upstream
(referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission
package, the right upstream sensor (2/1) is located in the right exhaust downpipe just before the
mini-catalytic convertor. The left upstream sensor (1/1) is located in the left exhaust downpipe just
before the mini-catalytic convertor. The right downstream sensor (2/2) is located in the right
exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor.
The left downstream sensor (1/2) is located in the left exhaust downpipe just after the mini-catalytic
convertor, and before the main catalytic convertor.
An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely
proportional to the amount of oxygen in the exhaust. In other words, if the oxygen content is low,
the voltage output is high; if the oxygen content is high the output voltage is low. The PCM uses
this information to adjust injector pulse-width to achieve the 14.7-to-1 air/fuel ratio necessary for
proper engine operation and to control emissions.
The O2 sensor must have a source of oxygen from outside of the exhaust stream for comparison.
Current O2 sensors receive their fresh oxygen (outside air) supply through the wire harness. This is
why it is important to never solder an O2 sensor connector, or pack the connector with grease.
Four wires (circuits) are used on each O2 sensor: a 12-volt feed circuit for the sensor heating
element; a ground circuit for the heater element; a low-noise sensor return circuit to the PCM, and
an input circuit from the sensor back to the PCM to detect sensor operation.
Oxygen Sensor Heater Relay: If the vehicle is equipped with 4 oxygen sensors, a separate oxygen
sensor relay is used to supply voltage to the sensor heating elements. This particular relay is used
only for the 1/2 and 2/2 downstream sensors. Voltage for the other 2 sensor heating elements is
supplied directly from the ASD relay.
To avoid the large simultaneous current surge needed to operate all 4 sensors, power is delayed to
the 2 downstream heater elements by the PCM for approximately 2 seconds.
Oxygen Sensor Heater Elements: The O2 sensor uses a Positive Thermal Co-efficient (PTC)
heater element. As temperature increases, resistance increases. At ambient temperatures around
70 °F, the resistance of the heating element is approximately 13.5 ohms on the this engine. As the
sensor's temperature increases, resistance in the heater element increases. This allows the heater
to maintain the optimum operating temperature of approximately 930 ° - 1100 °F (500 ° - 600 °C).
Although the sensors operate the same, there are physical differences, due to the environment that
they operate in, that keep them from being interchangeable.
Maintaining correct sensor temperature at all times allows the system to enter into closed loop
operation sooner. Also, it allows the system to remain in closed loop operation during periods of
extended idle.
In Closed Loop operation, the PCM monitors certain O2 sensor input(s) along with other inputs,
and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the
O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values
and inputs from other sensors.
Upstream Sensor - Engine Equipped With 2 Sensors: The upstream sensor (1/1) provides an input
voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses
this information to fine tune fuel delivery to maintain the correct oxygen content at the downstream
oxygen sensor. The PCM will change the air/fuel ratio until the upstream sensor inputs a voltage
that the PCM has determined will make the downstream sensor output (oxygen content) correct.
The upstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Downstream Sensor - Engine Equipped With 2 Sensors: The downstream oxygen sensor (1/2) is
also used to determine the correct air-fuel ratio. As the oxygen content changes at the downstream
sensor, the PCM calculates how much air-fuel ratio change is required. The PCM then looks at the
upstream oxygen sensor voltage and changes fuel delivery until the upstream sensor voltage
changes enough to correct the downstream sensor voltage (oxygen content).
The downstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Upstream Sensors - Engine Equipped With 4 Sensors: Two upstream sensors are used (1/1 and
2/1). The 1/1 sensor is the first sensor to receive exhaust gases from the # 1 cylinder. They provide
an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The
PCM uses this information to fine tune fuel delivery to maintain the correct oxygen content at the
downstream oxygen sensors. The PCM will change the air/fuel ratio until the upstream sensors
input a voltage that the PCM has determined will make the downstream sensors output (oxygen
content) correct.
The upstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.

Downstream Sensors - Engine Equipped With 4 Sensors: Two downstream sensors are used (1/2
and 2/2). The downstream sensors are used to determine the correct air-fuel ratio. As the oxygen
content changes at the downstream sensor, the PCM calculates how much air-fuel ratio change is
required. The PCM then looks at the upstream oxygen sensor voltage, and changes fuel delivery
until the upstream sensor voltage changes enough to correct the downstream sensor voltage
(oxygen content).
The downstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.
Engines equipped with either a downstream sensor(s), or a post-catalytic sensor, will monitor
catalytic convertor efficiency. If efficiency is below emission standards, the Malfunction Indicator
Lamp (MIL) will be illuminated and a Diagnostic Trouble Code (DTC) will be set. Refer to Monitored
Systems in Emission Control Systems for additional information.

REMOVAL
Never apply any type of grease to the oxygen sensor electrical connector, or attempt any soldering
of the sensor wiring harness. For sensor operation, it must have a comparison source of oxygen
from outside the exhaust system. This fresh air is supplied to the sensor through its pigtail wiring
harness.

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Central Timer Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation
Troubleshooting Tests

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Central Timer Module: Vehicle Damage Warnings
Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could
damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of
the original problem more difficult,
Road Testing A Complaint Vehicle
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE
REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB III SCREEN
WHILE IN MOTION. DO NOT HANG THE DRB III FROM THE REAR VIEW MIRROR OR

Description and Operation > Sytem Description
Central Timer Module: Description and Operation Sytem Description
The body system on the 2001 DN consists of a combination of modules that communicate over the
PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus,
information about the operation of vehicle components and circuits is relayed quickly to the
appropriate module(s). All modules receive all the information transmitted on the bus even though
a module may not require all information to perform its function. It will only respond to messages
"addressed" to it through a binary coding process. This method of data transmission significantly
reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the
information about the functioning of all the systems is organized, controlled, and communicated by
the PCI bus, which is described in the vehicle communication of this general information.

Indicators/Audible Warning Device
AIRBAG SYSTEM
The airbag system is designed to provide increased driver and passenger protection if the vehicle
is involved in a front end collision. The system is most effective when used in conjunction with the
seat belt system.
The Airbag Control Module (ACM) is an electronic module that monitors the airbag system for
proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and
contains the sensor and actuator that is responsible for airbag deployment. There are no external
impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck
at the bottom of the instrument panel. It is located forward of the console. The ACM provides
diagnostic information (DTCs) to the technician through the DRB III via the PCI bus. Some circuits
are tested continuously; others are checked only under certain circumstances. The warning lamp is
driven with messages relayed to the Electro/Mechanical Instrument Cluster (EMIC) from the ACM
via the PCI bus.
The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be
observed by the customer. Whenever the ignition key is turned to the "run" or "start" position, the
airbag control module performs a lamp check by turning the AIRBAG warning lamp ON for 6 - 8
seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to
be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the
system or the circuit that operates the lamp may be shorted to ground. If the lamp comes ON and
stays ON for a period longer than 6 - 8 seconds, then goes OFF, there is usually an intermittent
problem in the system.
WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT.
Seat Belt Tensioner
Front seat belt systems incorporate Tensioner Modules (SBT). At the onset of an impact event
each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to
rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact
will be reduced as will the likelihood of contacting interior components. After an impact that deploys
the airbag, the seat belt tensioner assembly must be replaced.
The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and
stored DTC's if any problem is found.
Airbag Diagnostic Trouble Codes
Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,
diagnostic priority should be given to the active codes.
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic
test procedures contain step-by-step instructions for determining the cause of the trouble codes. It
is not necessary to perform all of the tests in this book to diagnose an individual code.
Always begin by reading the diagnostic trouble codes using the DRB III.
Active diagnostic trouble codes for the airbag system are not permanent and will change the
moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes
are used as a diagnostic tool.
Active Codes
The code becomes active as soon as the malfunction is detected and stored after one minute of
occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going
malfunction. This means that the defect is currently there every time the airbag control module
checks that circuit/function. It is impossible to erase an active code; active codes automatically
erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is
detected, the airbag lamp remains lit for a minimum

Description and Operation > Sytem Description > Page 2610
of 12 seconds or as long as the malfunction is present.
Stored Codes
Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or
when the ignition is turned OFF. The exception is the "Loss of Ignition Run Only" code which is an
active code only.
A "stored" code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
When a trouble code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
The minimum time shown for any code will be one minute, even if the code was actually present for
less than one minute. Thus, the time shown for a code that was present for two minutes 13
seconds, for example, would be three minutes.
If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the
malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be
initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same
malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If
the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset
and the diagnostic trouble code will continue to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code
diagnostic test will not locate the source of the problem. In this case, the stored code can indicate
an area to inspect.
If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire
harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes
periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
AUDIO SYSTEM
The factory installed radio receiver communicates on the Programmable Communication Interface
(PCI) data bus network through a separate two-way wire harness connector. This is used for the
remote radio switches that are mounted to the steering wheel, and also used for radio diagnosis
with the DRB III.
The remote radio switches are resistor multiplexed units that are hard wired to the CTM through the
clockspring. The CTM monitors the status of the remote radio switches and sends the proper
switch status messages on the PCI data bus network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by
adjusting the radio settings as requested.
When troubleshooting output shorts or "output" error messages, the following applies: On radios
without an external amplifier, the term "output" refers to the path between the radio and the
speaker. This type of circuit can be monitored all the way through the speaker connections by the
radio assembly. When the radio displays a shorted output DTC with this type of system, the
speaker, radio or wiring could be at fault. The output DTC could refer to a front or rear output or a
left or right output. The reason for the difference is the pairing of the output sections of the radio.
Some are paired left and right, others are paired front and rear.
On radios with an external amplifier, the term "output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of monitoring only this portion and can tell nothing
about the circuit between the amplifier and the speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit. A faulty speaker could not cause this DTC.
CENTRAL TIMER MODULE
The Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or
Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.

The chime system is built into the CTM. There are two chime rates, Low: 50 chimes per minute for
reminders and High: 180 chimes per minute for serious conditions that require immediate attention.
The high rate chime sounds when the key is left in the ignition and the driver's door is open or if the
headlights or the courtesy lights are left on. The low rate chime sounds for any of the other
conditions. There is a variable rate feature that allows the chime to sound continuously for key-in
and headlamp warning as long as the door is open. The seat belt warning chime is activated for six
seconds, and all other chime conditions will activate the chime once at the same time the warning
light on the cluster is illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
COMPASS MINI-TRIP COMPUTER (CMTC)
This system, located in the overhead console, displays information on outside temperature,
compass direction and trip information.
Compass and Temperature Display This display provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is facing.
Trip Odometer (ODO) Shows the distance traveled since the last reset.

Automatic Compass Calibration This compass is self calibrating which eliminates the need to
manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL
symbol will be displayed. After completing three 360' turns in an area free from large metal or
metallic objects, the CAL symbol will turn OFF and the compass will function normally.
Compass Variance Compass Variance is the difference between Magnetic North and Geographic
North. In some areas of the country, the difference between Magnetic and Geographic North is
great enough to cause the compass to give false readings. If this occurs, the compass variance
must be set.
To Set the Variance Turn the ignition ON and set display to Comp./Temp. while pressing the US/M
button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the
last variance zone number will be displayed. Press the US/Metric Button to select the proper
variance zone as shown on the map. Press the Step button to set the new variance zone and
resume normal operation.
ELECTRO/MECHANICAL INSTRUMENT CLUSTER (EMIC)
The Instrument Cluster contains a Fuel, Voltmeter, Coolant Temp, and Oil Pressure gauge, a
Tachometer and a Speedometer. With the exception of the Voltmeter, the cluster positions the
gauges with PCI Bus messages received from the PCM. The Voltmeter operates directly off of the
Fused B+ Switched Ignition Output circuit that supplies ignition voltage for the cluster.
The Instrument Cluster also contains warning indicators that are illuminated by hard wired inputs or
by messages received from other modules on the PCI Bus.
The Trip/Total Odometer is a Vacuum Fluorescent Display (VF) that is controlled by PCI Bus
messages received from the PCM.
The cluster illumination lamps are hard wired in the Instrument Cluster. When the Park or
Headlamps are turned ON, the cluster receives a dimmed battery feed from the Headlamp Switch.
The cluster I/O Processor controls the VF display dimming and also sends dimming level
messages on the PCI Bus.
The EMIC will communicate with the DRB III to display PCI Engine Info, PCI Bus Info, and certain
input/outputs. Cluster diagnostic capabilities that the DRB III will actuate are limited to the Cluster
Calibration Points for the gauges. The DRB III can also extract active and stored Diagnostic
Trouble Codes (DTC) from the Instrument Cluster.
The EMIC is also capable of performing a diagnostic Self-Test that is actuated by depressing and
holding the Odometer trip reset stalk while cycling the ignition from the OFF to the ON position.
After the cluster Odometer displays CHEC, releasing the reset stalk begins the test. The cluster will
then position all of the gauges at specified calibration points and will illuminate all the PCI Bus
controlled indicators. The cluster will also illuminate each segment of the VF display.
The EMIC can verify communications with the PCM, ID the module, or change the country code
using the DRB III.
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI
bus to the CTM module to unlock the doors. The interior lights will be turned ON when the vehicle
speed message on the PCI bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time
following the deployment. Once the ignition key has been cycled to the "OFF" position, normal
operation will resume.
EXTERIOR LIGHTING
The low and high beam headlamps are controlled directly by an output from the Central Timer
Module (CTM). The park lamps and fog lamps (on vehicle so equipped) are controlled via external
relays that are energized by the CTM. The headlamp switch provides the control signal through the
multifunction switch to the CTM, which indicates low or high beam operation.
The Optical Horn (Flash to Pass) feature operates both the high beam and low beam headlamps.
The CTM provides the Headlamp Time Delay feature. To start the delay, turn the ignition OFF
while the headlamps are ON. Then turn the headlamp switch to the OFF position. This has to be
done within 45 seconds of the ignition being turned OFF. The headlamps will remain ON for 60 ± 5
seconds. If during this delay period the headlamp switch is turned ON and then OFF, or ignition
switch is turned ON delay will be canceled and they will turn OFF immediately. During the delay
period, only headlamps are turned ON and park lamps/fog lamps are turned OFF.
The CTM also provides battery protection to avoid wearing down the battery if the customer leaves
the park lamps or headlamps ON for extended period of time with the ignition OFF. If the park
lamps or headlamps remain ON for more than 5 minutes while the ignition is OFF, the headlamps
and park lamps shall be turned off and the input causing the lamps to be ON will be ignored until
the input is corrected. Once the 5 minute timeout has extinguished the headlamps and park lamps,
any change in the ignition switch, door ajar switches, headlamps switch or park lamp switch will
reset the 5 minute timer and return the headlamps and park lamps to normal operation.

HEATING & A/C SYSTEM
The all-new heating and air conditioning system for DN provides more heating and cooling capacity
than in previous years. Depending on the model, either a Dual-Zone Air Conditioning System or a
Three-Zone Air Conditioning System is currently available in these vehicles.
Air Distribution (Front)
The front compartment HVAC unit has four fully adjustable instrument panel outlets. Side-window
demister outlets in the instrument panel eliminate the need for door ducts and door-to-instrument
panel seals. A single central mounted outlet delivers air for defrosting the windshield. Two outlets,
one on each side of the center console underneath the instrument panel, provide airflow to the
driver floor area and to the front seat passenger floor area. While two additional outlets, one on
each side of the center console near the rear of the front seats, distribute both heated and cooled
air across the floor to the intermediate seat passengers. Ducts in the center of the vehicle
underneath the carpet deliver air from the front compartment HVAC unit to the two intermediate
passenger outlets.
Door Actuator Control
A simplified control system for operation of the mode, recirculation, and temperature control
actuators provides positive positioning without the complexity of feedback from position sensors.
The A/C - Heater Control Module knows the number of operating actuator revolutions required for
full door travel as well as the number of actuator commutator pulses per revolution. Using these
parameters, the A/C - Heater Control Module runs the actuator for the number of commutator
pulses that correspond to the desired door position. To maintain accuracy, the system recalibrates
itself periodically at known zero and full travel conditions.
The dual sliding Blend switches have multiple detents to control the full range of temperature that
the system can produce in any mode. On Dual-Zone systems, the upper slide pot controls the
driver-side blend door and the lower slide pot controls the passenger-side blend door. On
Three-Zone systems, the upper slide pot controls the driver-side blend door, while the lower slide
pot controls the passenger-side blend door and the rear A/C - heater unit blend door.
The single rotary Mode switch has 12 detents to either direct airflow to the panel outlets, to a mix of
floor and panel outlets, to the floor outlets, to a mix of floor and defrost outlets, or to the defrost
outlet. Rotating the Mode switch to either of the two MAX positions results in the A/C - Heater
Control Module sending a signal to the recirculation actuator to close the fresh-air door. While
rotating the Mode switch to any other position results in the A/C - Heater Control Module sending a
signal to the recirculation actuator to open the fresh-air door.
When the Blower switch is OFF, the A/C - Heater Control Module closes the fresh-air door to
prevent outside air from entering the vehicle. On Three- Zone systems, the Mode switch also
controls the rear A/C - heater unit mode door, which directs rear airflow either to the right quarter
trim panel outlet or to the overhead outlets.
Front Blower Control
The front blower circuitry employs a new resistor technology to control front blower speed. Called
the "credit card" resistor, the device looks much like its name in that it is thin and compact like a
credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the
front HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card
resistor offers much less airflow restriction.
A/C Operation
The A/C - Heater Control Module monitors the temperature of the evaporator to keep it just above
freezing for maximum cooling and dehumidification. A thermistor (temperature variable resistor)
placed between the evaporator fins provides the signal for the control. The Powertrain Control
Module (PCM) cycles the compressor on and off with a signal from the A/C - Heater Control
Module.
Heater Operation
To assist the HVAC system in maintaining a consistent and optimum heat output at low vehicle
speeds, an electric coolant pump operates under specific conditions to keep a steady flow of hot
coolant circulating through the heater circuit. The A/C - Heater Control Modules controls the
operation of the electric coolant pump. The pump runs when all of the following conditions are met:
When the vehicle's speed is below 27 Km/h (17 mph), the coolant temperature is between 65.5 °C
and 110 °C (150 °F and 230 °F), and the blend control is set above 60% reheat. The A/C - Heater
Control Module turns the pump OFF if any one of the following conditions occur: The vehicle speed
rises above 48.3 Km/h (30 mph). The coolant temperature drops below 65.5 °C (150 °F). The
coolant temperature rises above 110 °C (230 °F). The blend control is set below 60% reheat.
A/C - Heater Control (Rear)
The Three-Zone system allows the intermediate seat occupants to regulate the air temperature and
the fan speed of the rear unit from the rotary controls on the headliner mounted Rear A/C - Heater
Control.
HVAC Diagnostics
The A/C - Heater Control Module is fully addressable with the DRB III. Two of the Control Module's
diagnostic capabilities that the DRB III will actuate include the A/C Cool down Test to test A/C
system performance and the HVAC Door Recalibration Test to determine actuator travel span.
After performing either test, the Control Module will display one or more messages on the DRB III
screen. The message will indicate either that the HVAC system passed the test or that there is a
fault currently active in the HVAC system. The DRB III can also extract active and stored
Diagnostic Trouble Codes (DTCs) from the control module. Active DTCs are faults that currently
exit in the HVAC system. Stored DTCs are faults that occurred in the HVAC system since the
control module received the last "clear diagnostic info" message.
INTERIOR LIGHTING

Description and Operation > Sytem Description > Page 2614
The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module
(CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when
either the dome lamp switch is turned ON or a door is opened. The courtesy lamps will fade to OFF
immediately when all doors are closed with the dome lamp switch in the OFF position.
The illuminated entry feature operates under the following conditions: RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned ON
Once activated, the illuminated entry will "fade to OFF" after 3 to 5 seconds under the following
conditions: All doors are closed and: RKE "lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will not reset timer.
Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and
the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp
position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps.
The Interior lamp defeat feature will not allow any interior lamp to be turned ON. This is
accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps due to the following.
Leaving a door open, dome lamp switch ON, reading/vanity lamp switch ON or glove box door
open for more than 15 minutes while the ignition is OFF.
POWER DOOR LOCKS/REMOTE KEYLESS ENTRY
The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key
fob or interior switch.
Vehicles that are equipped with the Vehicle Theft Security System will also have the central locking
feature. With the central locking feature, when the cylinder lock switch is turned to the lock position
all the doors will lock. For unlocking, if the key is turned to the unlock position once, only that door
will unlock. If the key is then turned a second time to the unlock position, all the doors will unlock.
There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is
OFF and the key is in the ignition.
Automatic or "rolling locks" are included as a programmable feature. If the vehicle is moving
approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the
PCM will send this info to the CTM via the PCI bus) indicating acceleration, the CTM will cycle the
lock actuators to lock the doors.
The highline CTM provides for Remote Keyless Entry (RKE)
The RKE system is placed in the programming mode by the DRB III, or by the customer program
features. The system will store up to four key fob codes. Two fobs are supplied with the truck,
additional fobs may be purchased through the parts department. Through the DRB III, erasing and
programming of one key fob without deleting the others is possible. If the key fob is stolen, all the
fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense
of security.
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network
capable of supporting binary encoded messages shared between multiple modules. The PCI bus
circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added
to the yellow in order to distinguish between different module connections. The modules are wired
in parallel. Connections are made in the harness using a splice.
The splice called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit. The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 2615
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The
bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and
a half volts when modules are transmitting.
The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only
voltage present when the modules transmit and the message length is only about 500 milliseconds,
it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred
method is to use the DRB III lab scope. The 12v square wave selection on the 20-volt scale
provides a good view of the bus activity. Voltage on the bus should pulse between zero and about
seven and a half volts. Refer to the figure for some typical displays.
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Central Timer Module <--> [Body Control Module] > Component Information >
Description and Operation > Sytem Description > Page 2616
- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.
VEHICLE THEFT SECURITY SYSTEM
The VTSS system monitors the door ajar switches, and ignition switch to detect unauthorized entry
into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system
to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to
start the engine with a non-programmed SKIM key, it will start and stall. If the trigger condition is
still present, the lights will continue to flash for an additional 15 minutes, after which the system will
stop pulsing the lights and return to the "armed" state. The cause of the last 4 alarm triggers is
stored by the CTM and may be retrieved by the DRB III. The system may be disarmed by either an
unlock command from a valid RKE key fob by using a key in either door, or by using a valid SKIM
key in the ignition. The door key cylinders are equipped with disarm switches. There is also a VTSS
lamp on the dash that provides information to the driver about the state of the vehicle theft system.
WINDSHIELD WIPER SYSTEM
The DN truck is equipped with speed sensitive intermittent wipers. The low and high speeds are
controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by
the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as
selected by the driver, an immediate wipe of the windshield takes place and the new delay interval
is implemented.

Central Timer Module: Symptom Related Diagnostic Procedures
Non-Trouble Code Procedures
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module.
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING
FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
NOTE: The following tests may not prove conclusive in the diagnosis of the Central Timer Module
(CTM). The most reliable, efficient, and accurate means to diagnose the CTM requires the use of a
DRB III scan tool. Refer to the appropriate diagnostic information.
1. Check the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20 ampere) in the Power
Distribution Center (PDC). If OK, go to Step 2. If not
OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Check for battery voltage at the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20
ampere) in the PDC. If OK, go to Step 3. If not OK,
repair the open B(+) circuit between the PDC and the battery as required.
3. Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness
connector (Connector C3) for the CTM from the
CTM connector receptacle. Reconnect the battery negative cable. Check for battery voltage at
each of the two fused B(+) circuit cavities of the instrument panel wire harness connector
(Connector C3) for the CTM. If OK, disconnect and isolate the battery negative cable, reconnect
the instrument panel wire harness connector (Connector C3) for the CTM to the CTM connector
receptacle, and go to Step 4. If not OK, repair the open fused B(+) circuit(s) between the CTM and
the PDC as required.
4. Check the fused ignition switch output (run-start) fuse (Fuse 11 - 10 ampere) and the fused
ignition switch output (run-acc) fuse (Fuse 5 - 20
ampere) in the Junction Block (JB). If OK, go to Step 5. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse(s).
5. Reconnect the battery negative cable. Turn the ignition switch to the ON position. Check for
battery voltage at the fused ignition switch output
(run-start) fuse (Fuse 11 - 10 ampere) and the fused ignition switch output (run-acc) fuse (Fuse 5 20 ampere) in the JB. If OK, go to Step 6. If not OK, repair the open fused ignition switch output

DRB III ERROR MESSAGES AND BLANK SCREEN
Under normal operation, the DRB III will display one of only two error messages:
User-Requested WARM Boot (Press MORE and NO at the same time)
User-Requested COLD Boot (Press MORE and YES at the same time)
If the DRB III should display any other error message, record the entire display and call the
S.T.A.R. Center for information and assistance.
DRB III DOES NOT POWER UP
If the LED's do not light or no sound is emitted at start up, check for loose cable connections or a
bad cable. Check the vehicle battery voltage (data link connector cavity 16). A minimum of 11 volts
is required to adequately power the DRB III.
If all connections are proper between the DRB III and the vehicle or other devices, and the vehicle
battery is fully charged, and inoperative DRB III may be the result of faulty cable or vehicle wiring.
For a blank screen, refer to the appropriate body diagnostics.
DISPLAY IS NOT VISIBLE
Low temperatures will affect the visibility of the display. Adjust the contrast to compensate for this
condition
SOME DISPLAY ITEMS READ "---"
This is caused by scrolling the DRB III display a single line up or down. The line which was scrolled
onto the screen might read "---". Use the Page

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

NOTE:
The model years and vehicles above must be equipped (optional) with Sentry Key Theft Deterrent
System (sales code GXX) for this bulletin to apply.
DISCUSSION:
ALL LISTED VEHICLES EXCEPT SEBRING COUPE/STRATUS COUPE (ST), CROSSFIRE, AND
SPRINTER.
When a Powertrain Control Module (PCM) is replaced on vehicles equipped with the Sentry
Key(TM) Theft Deterrent System, it must be initialized to properly function with the anti-theft
module. This is accomplished at a Chrysler Group Dealer by using the DRBIII(R) or StarSCAN(TM)
Scan Tool to enter a PIN number.
When the PIN number is not available from the vehicle owner or a Chrysler Group Scan Tool(s) is
not available this can be accomplished by writing the Vehicle Identification Number (VIN) into the
PCM using an after-market scan tool with a "VIN Write Function".
More information is available from the scan tool manufacturer or the Equipment & Tool Institute.
NOTE:
After performing this procedure with an after-market scan tool on vehicles equipped with Chrysler
Group's Next Generation Controller (NGC), Diagnostic Trouble Code (DTC) "P0633 - SKIM
SECRET KEY DATA NOT STORED IN PCM" will be set. This DTC will not effect vehicle or system
performance and cannot be erased.
SEBRING COUPE/STRATUS COUPE (ST)
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
J1962 MMC Cable (Special Tool CH7010), and the BLUE 5T22 PCMCIA
Diagnostic Card (Special Tool CH8425). This equipment is available for lease from
DaimlerChrysler for short periods of time. A credit card deposit will be required.
CROSSFIRE AND SPRINTER.
Initializing the PCM on these vehicles requires the use of a DaimlerChrysler scan tool (DRBIII(R)),
Multiplexer cable box (Special Tool CH 9043), and the ORANGE Crossfire PCMCIA card (Special
Tool CH9044) or the GREEN Sprinter PCMCIA card (Special Tool CH9087). This equipment is
available for lease from DaimlerChrysler for short periods of time. A credit card deposit will be
required.
The DRBIII(R) will be shipped within 24 hours to your location by an overnight delivery service.
When the DRBIII(R) is returned, your credit card will be charged the lease price.
2007 GRAND CHEROKEE W/ 3.0L TD/2005 - 2007 LIBERTY w/2.8L TD/2007 RAM TRUCK/RAM
CAB CHASSIS w 6.7L TD AND 2004-2006 SPRINTER w 2.7L TD ENGINES.
For the above models equipped with Turbo Diesel Engines, the fuel injector "Quantity Values" must
be physically read from each injector and the values written to the ECU with an appropriate scan
tool.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information >
Diagrams > Diagram Information and Instructions > Page 2665
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information >
Diagrams > Diagram Information and Instructions > Page 2666
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.
Circuit Information

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information >
Diagrams > Diagram Information and Instructions > Page 2667
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Diagrams > Diagram Information and Instructions > Page 2668
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Powertrain Control Module: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Powertrain Control Module: Description and Operation
Fig. 9 PCM Location
POWERTRAIN CONTROL MODULE
The Powertrain Control Module (PCM) is located in the engine compartment. The PCM is referred
to as JTEC.
The PCM operates the fuel system. The PCM is a pre-programmed, triple microprocessor digital
computer. It regulates ignition timing, air-fuel ratio, emission control devices, charging system,
certain transmission features, speed control, air conditioning compressor clutch engagement and
idle speed. The PCM can adapt its programming to meet changing operating conditions.
The PCM receives input signals from various switches and sensors. Based on these inputs, the
PCM regulates various engine and vehicle operations through different system components. These
components are referred to as Powertrain Control Module (PCM) Outputs. The sensors and
switches that provide inputs to the PCM are considered Powertrain Control Module (PCM) Inputs.
The PCM adjusts ignition timing based upon inputs it receives from sensors that react to: engine
rpm, manifold absolute pressure, engine coolant temperature, throttle position, transmission gear
selection (automatic transmission), vehicle speed and the brake switch.
The PCM adjusts idle speed based on inputs it receives from sensors that react to: throttle position,
vehicle speed, transmission gear selection, engine coolant temperature and from inputs it receives
from the air conditioning clutch switch and brake switch.
Based on inputs that it receives, the PCM adjusts ignition coil dwell. The PCM also adjusts the
generator charge rate through control of the generator field and provides speed control operation.

MODES OF OPERATION
As input signals to the Powertrain Control Module (PCM) change, the PCM adjusts its response to
the output devices. For example, the PCM must calculate different injector pulse width and ignition
timing for idle than it does for wide open throttle (WOT).
The PCM will operate in two different modes: Open Loop and Closed Loop.
During Open Loop modes, the PCM receives input signals and responds only according to preset
PCM programming. Input from the oxygen (O2S) sensors is not monitored during Open Loop
modes.
During Closed Loop modes, the PCM will monitor the oxygen (O2S) sensors input. This input
indicates to the PCM whether or not the calculated injector pulse width results in the ideal air-fuel
ratio. This ratio is 14.7 parts air-to-1 part fuel. By monitoring the exhaust oxygen content through
the O2S sensor, the PCM can fine tune the injector pulse width. This is done to achieve optimum
fuel economy combined with low emission engine performance.
The fuel injection system has the following modes of operation: Ignition switch ON
- Engine start-up (crank)
- Engine warm-up
- Idle
- Cruise
- Acceleration
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Relays and Modules Computers and Control Systems > Powertrain Control Module <--> [Engine Control Module] > Component Information >
Diagrams > Page 2691
- Deceleration
- Wide open throttle (WOT)
- Ignition switch OFF
The ignition switch ON, engine start-up (crank), engine warm-up, acceleration, deceleration and
wide open throttle modes are Open Loop modes. The idle and cruise modes, (with the engine at
operating temperature) are Closed Loop modes.
Ignition Switch (KEY-ON) Mode This is an Open Loop mode. When the fuel system is activated by
the ignition switch, the following actions occur: The PCM pre-positions the idle air control (IAC) motor.
- The PCM determines atmospheric air pressure from the MAP sensor input to determine basic fuel
strategy.
- The PCM monitors the engine coolant temperature sensor input. The PCM modifies fuel strategy
based on this input.
- Intake manifold air temperature sensor input is monitored.
- Throttle position sensor (TPS) is monitored.
- The auto shutdown (ASD) relay is energized by the PCM for approximately three seconds.
- The fuel pump is energized through the fuel pump relay by the PCM. The fuel pump will operate
for approximately three seconds unless the engine is operating or the starter motor is engaged.
- The 02S sensor heater element is energized via the ASD relay. The 02S sensor input is not used
by the PCM to calibrate air-fuel ratio during this mode of operation.
Engine Start-Up Mode This is an Open Loop mode. The following actions occur when the starter
motor is engaged.The PCM receives inputs from: Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Starter motor relay
- Camshaft position sensor signal
The PCM monitors the crankshaft position sensor. If the PCM does not receive a crankshaft
position sensor signal within 3 seconds of cranking the engine, it will shut down the fuel injection
system.
The fuel pump is activated by the PCM through the fuel pump relay.
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
The PCM determines the proper ignition timing according to input received from the crankshaft
position sensor.
Engine Warm-Up Mode This is an Open Loop mode. During engine warmup, the PCM receives
inputs from: Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto.trans. only)
- Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
Based on these inputs the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF.
- The PCM adjusts engine idle speed through the idle air control (IAC) motor and adjusts ignition
timing.
- The PCM operates the A/C compressor clutch through the clutch relay. This is done if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
- When engine has reached operating temperature, the PCM will begin monitoring 02S sensor
input. The system will then leave the warm-up mode and go into closed loop operation.
Idle Mode When the engine is at operating temperature, this is a Closed Loop mode. At idle speed,
the PCM receives inputs from: Air conditioning select signal (if equipped)

- Air conditioning request signal (if equipped)
- Battery voltage
- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Battery voltage
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen sensors
Based on these inputs, the following occurs: Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control
injection sequence and injector pulse width by turning the ground circuit to each individual injector
ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio by varying injector pulse width.It
also adjusts engine idle speed through the idle air control (IAC) motor.
- The PCM adjusts ignition timing by increasing and decreasing spark advance.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Cruise Mode When the engine is at operating temperature, this is a Closed Loop mode. At cruising
speed, the PCM receives inputs from: Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Oxygen (O2S) sensors
Based on these inputs, the following occurs: -
Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then adjust
the injector pulse width by turning the ground circuit to each individual injector ON and OFF.
- The PCM monitors the 02S sensor input and adjusts air-fuel ratio. It also adjusts engine idle
speed through the idle air control ('AC) motor.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
- The PCM operates the A/C compressor clutch through the clutch relay. This happens if A/C has
been selected by the vehicle operator and requested by the A/C thermostat.
Acceleration Mode This is an Open Loop mode. The PCM recognizes an abrupt increase in throttle
position or MAP pressure as a demand for increased engine output and vehicle acceleration. The
PCM increases injector pulse width in response to increased throttle opening.
Deceleration Mode When the engine is at operating temperature, this is an Open Loop mode.
During hard deceleration, the PCM receives the following inputs. Air conditioning select signal (if equipped)
- Air conditioning request signal (if equipped)
- Battery voltage
- Engine coolant temperature sensor
- Crankshaft position sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)
- Park/neutral switch (gear indicator signal-auto. trans. only)
- Vehicle speed sensor
If the vehicle is under hard deceleration with the proper rpm and closed throttle conditions, the
PCM will ignore the oxygen sensor input signal. The PCM will enter a fuel cut-off strategy in which
it will not supply a ground to the injectors. If a hard deceleration does not exist, the PCM will
determine the proper injector pulse width and continue injection.
Based on the above inputs, the PCM will adjust engine idle speed through the idle air control (IAC)
motor.

- Crankshaft position sensor
- Engine coolant temperature sensor
- Intake manifold air temperature sensor
- Manifold absolute pressure (MAP) sensor
- Throttle position sensor (TPS)
- Camshaft position sensor signal (in the distributor)

the injection sequence and injector pulse width by turning the ground circuit to each individual
injector ON and OFF. The PCM ignores the oxygen sensor input signal and provides a
predetermined amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil ON and OFF.
ignition switch OFF Mode When ignition switch is turned to OFF position, the PCM stops operating
the injectors, ignition coil, ASD relay and fuel pump relay.
5 VOLT SUPPLIES
Two different Powertrain Control Module (PCM) five volt supply circuits are used; primary and
secondary.
Primary 5-volt supply: supplies the required 5 volt power source to the Crankshaft Position (CKP) sensor.
- supplies the required 5 volt power source to the Camshaft Position (CMP) sensor.
- supplies a reference voltage for the Manifold Absolute Pressure (MAP) sensor.
- supplies a reference voltage for the Throttle Position Sensor (TPS) sensor.
Secondary 5-volt supply: supplies the required 5 volt power source to the oil pressure sensor.
- supplies the required 5 volt power source for the Vehicle Speed Sensor (VSS) (if equipped).
- supplies the 5 volt power source to the transmission pressure sensor (if equipped with an RE
automatic transmission).
IGNITION CIRCUIT SENSE
This circuit ties the ignition switch to the Power- train Control Module (PCM).
The ignition circuit sense input tells the PCM the ignition switch has energized the ignition circuit.
Battery voltage is also supplied to the PCM through the ignition switch when the ignition is in the
RUN or START position. This is referred to as the "ignition sense" circuit and is used to "wake up"
the PCM. Voltage ON the ignition input can be as low as 6 volts and the PCM will still function.
Voltage is supplied to this circuit to power the PCM's 8-volt regulator and to allow the PCM to
perform fuel, ignition and emissions control functions.
POWER GROUND
The Powertrain Control Module (PCM) has 2 main grounds. Both of these grounds are referred to
as power grounds. All of the high-current, noisy, electrical devices are connected to these grounds
as well as all of the sensor returns. The sensor return comes into the sensor return circuit, passes
through noise suppression, and is then connected to the power ground.
The power ground is used to control ground circuits for the following PCM loads: Generator field winding
- Fuel injectors
- Ignition coil(s)
- Certain relays/solenoids
- Certain sensors
SENSOR RETURN
The Sensor Return circuits are internal to the Powertrain Control Module (PCM).
Sensor Return provides a low-noise ground reference for all engine control system sensors. Refer
to Power Grounds for more information.
SIGNAL GROUND
Signal ground provides a low noise ground to the data link connector.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Fig. 2 ASD And Fuel Pump Terminals - Type 2
The following description of operation and tests apply only to the Automatic Shutdown (ASD) and
fuel pump relays. The terminals on the bottom of each relay are numbered. Two different types of
relays may be used, or.
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays,
terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to
terminal 30. This is the OFF position. In the OFF position, voltage is not supplied to the rest of the
circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30.
This is the ON position. Terminal 87 supplies voltage to the rest of the circuit.
The following procedure applies to the ASD and fuel pump relays.

ohmmeter to check the resistance between terminals 85 and 86. The resistance should be 75
ohms
± 5 ohms.
3. Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity
between terminals 30 and 87A. 4. Connect the ohmmeter between terminals 87 and 30. The
ohmmeter should not show continuity at this time. 5. Connect one end of a jumper wire (16 gauge
or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12
volt power source.
6. Connect one end of another jumper wire (16 gauge or smaller) to the power side of the 12 volt
power source. Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS
TEST. DAMAGE TO OHMMETER MAY RESULT.
7. Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The
ohmmeter should now show continuity between relay
terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and
30.
8. Disconnect jumper wires. 9. Replace the relay if it did not pass the continuity and resistance
tests. If the relay passed the tests, it operates properly. Check the remainder of the
ASD and fuel pump relay circuits.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Engine Coolant Temperature (ECT) Sensor: Description and Operation
DESCRIPTION
The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The
sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine
coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
OPERATION
At key-on, the Powertrain Control Module (PCM) sends out a regulated 5 volt signal to the ECT
sensor. The PCM then monitors the signal as it passes through the ECT sensor to the sensor
ground (sensor return).
When the engine is cold, the PCM will operate in Open Loop cycle. It will demand slightly richer air
fuel mixtures and higher idle speeds. This is done until normal operating temperatures are reached.
The PCM uses inputs from the ECT sensor for the following calculations: ^
for engine coolant temperature gauge operation through CCD or PCI (J1850)
^ Communications
^ Injector pulse-width
^ Spark-advance curves
^ ASD relay shut-down times
^ Idle Air Control (IAC) motor key-on steps
^ Pulse-width prime-shot during cranking
^ 02 sensor closed loop times
^ Purge solenoid on/off times
^ EGR solenoid on/off times (if equipped)
^ Leak Detection Pump operation (if equipped)
^ Radiator fan relay on/off times (if equipped)
^ Target idle speed

Dodge Workshop Manuals > Powertrain Management > Computers and Control Systems > Sensors and Switches Computers and Control Systems > Fuel Level Sensor > Component Information > Locations > Page 2750
Fuel Level Sensor: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Intake Air Temperature (IAT) Sensor: Description and Operation
The 2-wire Intake Manifold Air Temperature (IAT) sensor is installed in the intake manifold with the
sensor element extending into the air stream.
The IAT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as intake
manifold temperature increases, resistance (voltage) in the sensor decreases. As temperature
decreases, resistance (voltage) in the sensor increases.
The IAT sensor provides an input voltage to the Powertrain Control Module (PCM) indicating the
density of the air entering the intake manifold based upon intake manifold temperature. At key-ON,
a 5-volt power circuit is supplied to the sensor from the PCM. The sensor is grounded at the PCM
through a low-noise, sensor-return circuit.
The PCM uses this input to calculate the following:
- Injector pulse-width
- Adjustment of spark timing (to help prevent spark knock with high intake manifold air-charge
temperatures)
The resistance values of the IAT sensor is the same as for the Engine Coolant Temperature (ECT)
sensor.

Manifold Absolute Pressure (MAP) Sensor: Description and Operation
The MAP sensor is located on the front of the intake manifold. An O-ring seals the sensor to the
intake manifold.
The MAP sensor is used as an input to the Powertrain Control Module (PCM). It contains a silicon
based sensing unit to provide data on the manifold vacuum that draws the air/fuel mixture into the
combustion chamber. The PCM requires this information to determine injector pulse width and
spark advance. When manifold absolute pressure (MAP) equals Barometric pressure, the pulse
width will be at maximum.
A 5 volt reference is supplied from the PCM and returns a voltage signal to the PCM that reflects
manifold pressure. The zero pressure reading is 0.5V and full scale is 4.5V. For a pressure swing
of 0-15 psi, the voltage changes 4.0V To operate the sensor, it is supplied a regulated 4.8 to 5.1
volts. Ground is provided through the low-noise, sensor return circuit at the PCM.
The MAP sensor input is the number one contributor to fuel injector pulse width. The most
important function of the MAP sensor is to determine barometric pressure. The PCM needs to
know if the vehicle is at sea level or at a higher altitude, because the air density changes with
altitude. It will also help to correct for varying barometric pressure. Barometric pressure and altitude
have a direct inverse correlation; as altitude goes up, barometric goes down. At key-ON, the PCM
powers up and looks at MAP voltage, and based upon the voltage it sees, it knows the current
barometric pressure (relative to altitude). Once the engine starts, the PCM looks at the voltage
again, continuously every 12 milliseconds, and compares the current voltage to what it was at
key-on. The difference between current voltage and what it was at key-on, is manifold vacuum.
During key-ON (engine not running) the sensor reads (updates) barometric pressure. A normal
range can be obtained by monitoring a known good sensor.
As the altitude increases, the air becomes thinner (less oxygen). If a vehicle is started and driven to
a very different altitude than where it was at key-ON, the barometric pressure needs to be updated.
Any time the PCM sees Wide Open Throttle (WOT), based upon Throttle Position Sensor (TPS)
angle and RPM, it will update barometric pressure in the MAP memory cell. With periodic updates,
the PCM can make its calculations more effectively.
The PCM uses the MAP sensor input to aid in calculating the following:
- Manifold pressure
- Barometric pressure
- Engine load
- Injector pulse-width
- Spark-advance programs
- Shift-point strategies (certain automatic transmissions only)
- Idle speed
- Decel fuel shutoff
The MAP sensor signal is provided from a single piezoresistive element located in the center of a
diaphragm. The element and diaphragm are both made of silicone. As manifold pressure changes,
the diaphragm moves causing the element to deflect, which stresses the silicone. When silicone is
exposed to stress, its resistance changes. As manifold vacuum increases, the MAP sensor input
voltage decreases proportionally. The sensor also contains electronics that condition the signal and
provide temperature compensation.
The PCM recognizes a decrease in manifold pressure by monitoring a decrease in voltage from the
reading stored in the barometric pressure memory cell. The MAP sensor is a linear sensor;
meaning as pressure changes, voltage changes proportionately. The range of voltage output from
the sensor is usually between 4.6 volts at sea level to as low as 0.3 volts at 26 in. of Hg. Barometric
pressure is the pressure exerted by the atmosphere upon an object. At sea level on a standard
day, no storm, barometric pressure is approximately 29.92 in Hg. For every 100 feet of altitude,
barometric pressure drops 0.10 in. Hg. If a storm goes through it can change barometric pressure
from what should be present for that altitude. You should know what the average pressure and
corresponding barometric pressure is for your area.

DESCRIPTION
The 2-wire, electrical/mechanical engine oil pressure sensor (sending unit) is located in an engine
oil pressure gallery.
OPERATION
The oil pressure sensor uses two circuits. They are: ^
A signal to the PCM relating to engine oil pressure
^ A sensor ground through the PCM's sensor return
The oil pressure sensor returns a voltage signal back to the PCM relating to engine oil pressure.
This signal is then transferred (bussed) to the instrument panel on a CCD bus circuit to operate the
oil pressure gauge and the check gauges lamp. Ground for the sensor is provided by the PCM
through a low noise sensor return.

Oxygen Sensor: Description and Operation
The Oxygen Sensors (O2S) are attached to, and protrude into the vehicle exhaust system.
Depending on the emission package, the vehicle may use a total of either 2 or 4 sensors.
NAA Emissions Package: Two sensors are used: upstream (referred to as 1/1) and downstream
(referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before
the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic
convertor.
NAS or NAE Emissions Package: On this emissions package, 4 sensors are used: 2 upstream
(referred to as 1/1 and 2/1) and 2 downstream (referred to as 1/2 and 2/2). With this emission
package, the right upstream sensor (2/1) is located in the right exhaust downpipe just before the
mini-catalytic convertor. The left upstream sensor (1/1) is located in the left exhaust downpipe just
before the mini-catalytic convertor. The right downstream sensor (2/2) is located in the right
exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor.
The left downstream sensor (1/2) is located in the left exhaust downpipe just after the mini-catalytic
convertor, and before the main catalytic convertor.
An O2 sensor is a galvanic battery that provides the PCM with a voltage signal (0-1 volt) inversely
proportional to the amount of oxygen in the exhaust. In other words, if the oxygen content is low,
the voltage output is high; if the oxygen content is high the output voltage is low. The PCM uses
this information to adjust injector pulse-width to achieve the 14.7-to-1 air/fuel ratio necessary for
proper engine operation and to control emissions.
The O2 sensor must have a source of oxygen from outside of the exhaust stream for comparison.
Current O2 sensors receive their fresh oxygen (outside air) supply through the wire harness. This is
why it is important to never solder an O2 sensor connector, or pack the connector with grease.
Four wires (circuits) are used on each O2 sensor: a 12-volt feed circuit for the sensor heating
element; a ground circuit for the heater element; a low-noise sensor return circuit to the PCM, and
an input circuit from the sensor back to the PCM to detect sensor operation.
Oxygen Sensor Heater Relay: If the vehicle is equipped with 4 oxygen sensors, a separate oxygen
sensor relay is used to supply voltage to the sensor heating elements. This particular relay is used
only for the 1/2 and 2/2 downstream sensors. Voltage for the other 2 sensor heating elements is
supplied directly from the ASD relay.
To avoid the large simultaneous current surge needed to operate all 4 sensors, power is delayed to
the 2 downstream heater elements by the PCM for approximately 2 seconds.
Oxygen Sensor Heater Elements: The O2 sensor uses a Positive Thermal Co-efficient (PTC)
heater element. As temperature increases, resistance increases. At ambient temperatures around
70 °F, the resistance of the heating element is approximately 13.5 ohms on the this engine. As the
sensor's temperature increases, resistance in the heater element increases. This allows the heater
to maintain the optimum operating temperature of approximately 930 ° - 1100 °F (500 ° - 600 °C).
Although the sensors operate the same, there are physical differences, due to the environment that
they operate in, that keep them from being interchangeable.
Maintaining correct sensor temperature at all times allows the system to enter into closed loop
operation sooner. Also, it allows the system to remain in closed loop operation during periods of
extended idle.
In Closed Loop operation, the PCM monitors certain O2 sensor input(s) along with other inputs,
and adjusts the injector pulse width accordingly. During Open Loop operation, the PCM ignores the
O2 sensor input. The PCM adjusts injector pulse width based on preprogrammed (fixed) values
and inputs from other sensors.
Upstream Sensor - Engine Equipped With 2 Sensors: The upstream sensor (1/1) provides an input
voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The PCM uses
this information to fine tune fuel delivery to maintain the correct oxygen content at the downstream
oxygen sensor. The PCM will change the air/fuel ratio until the upstream sensor inputs a voltage
that the PCM has determined will make the downstream sensor output (oxygen content) correct.
The upstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Downstream Sensor - Engine Equipped With 2 Sensors: The downstream oxygen sensor (1/2) is
also used to determine the correct air-fuel ratio. As the oxygen content changes at the downstream
sensor, the PCM calculates how much air-fuel ratio change is required. The PCM then looks at the
upstream oxygen sensor voltage and changes fuel delivery until the upstream sensor voltage
changes enough to correct the downstream sensor voltage (oxygen content).
The downstream oxygen sensor also provides an input to determine catalytic convertor efficiency.
Upstream Sensors - Engine Equipped With 4 Sensors: Two upstream sensors are used (1/1 and
2/1). The 1/1 sensor is the first sensor to receive exhaust gases from the # 1 cylinder. They provide
an input voltage to the PCM. The input tells the PCM the oxygen content of the exhaust gas. The
PCM uses this information to fine tune fuel delivery to maintain the correct oxygen content at the
downstream oxygen sensors. The PCM will change the air/fuel ratio until the upstream sensors
input a voltage that the PCM has determined will make the downstream sensors output (oxygen
content) correct.
The upstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.

Downstream Sensors - Engine Equipped With 4 Sensors: Two downstream sensors are used (1/2
and 2/2). The downstream sensors are used to determine the correct air-fuel ratio. As the oxygen
content changes at the downstream sensor, the PCM calculates how much air-fuel ratio change is
required. The PCM then looks at the upstream oxygen sensor voltage, and changes fuel delivery
until the upstream sensor voltage changes enough to correct the downstream sensor voltage
(oxygen content).
The downstream oxygen sensors also provide an input to determine mini-catalyst efficiency. Main
catalytic convertor efficiency is not calculated with this package.
Engines equipped with either a downstream sensor(s), or a post-catalytic sensor, will monitor
catalytic convertor efficiency. If efficiency is below emission standards, the Malfunction Indicator
Lamp (MIL) will be illuminated and a Diagnostic Trouble Code (DTC) will be set. Refer to Monitored
Systems in Emission Control Systems for additional information.

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Component Information > Specifications > Page 2839
Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

a result of overheating. If the converter has a heat shield attached make sure it is not bent or loose.
If you suspect internal damage to the catalyst, tapping the bottom of the catalyst with a rubber
mallet may indicate a damaged core.
INSTALLATION
CAUTION: When servicing or replacing exhaust system components, disconnect the oxygen
sensor connector(s). Allowing the exhaust to hang by the oxygen sensor wires will damage the
harness and/or sensor.
1. Align and connect the catalytic converter flange to the exhaust pipe.

Canister Purge Solenoid: Description and Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the
EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the
solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during
open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay
ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or
10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by
changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized.
The PCM adjusts solenoid pulse width based on engine operating condition.

INTRODUCTION
The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel
system. Leaks in the system, even small ones, can allow fuel vapors to escape into the
atmosphere. Government regulations require on-board testing to make sure that the evaporative
(EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and
blockage. It also performs self-diagnostics.
During self-diagnostics, the Powertrain Control Module (PCM) first checks the Leak Detection
Pump (LDP) for electrical and mechanical faults. If the first checks pass, the PCM then uses the
LDP to seal the vent valve and pump air into the system to pressurize
it. If a leak is present, the PCM will continue pumping the LDP to replace the air that leaks out. The
PCM determines the size of the leak based on how fast/long it must pump the LDP as it tries to
maintain pressure in the system.

EVAP LEAK DETECTION SYSTEM COMPONENTS
Service Port: Used with special tools like the Miller Evaporative Emissions Leak Detector (EELD) to
test for leaks in the system.
EVAP Purge Solenoid: The PCM uses the EVAP purge solenoid to control purging of excess fuel
vapors stored in the EVAP canister. It remains closed during leak testing to prevent loss of
pressure.
EVAP Canister The EVAP canister stores fuel vapors from the fuel tank for purging. EVAP Purge
Orifice: Limits purge volume.
EVAP System Air Filter: Provides air to the LDP for pressurizing the system. It filters out dirt while
allowing a vent to atmosphere for the EVAP system.
Leak Detection Pump (LDP) Components
The main purpose of the LDP is to pressurize the fuel system for leak checking. It closes the EVAP
system vent to atmospheric pressure so the system can be pressurized for leak testing. The
diaphragm is powered by engine vacuum. It pumps air into the EVAP system to develop a pressure
of about 7.5' H20(1/4) psi. A reed switch in the LDP allows the PCM to monitor the position of the
LDP diaphragm. The PCM uses the reed switch input to monitor how fast the LDP is pumping air
into the EVAP system. This allows detection of leaks and blockage.
The LDP assembly consists of several parts. The solenoid is controlled by the PCM, and it
connects the upper pump cavity to either engine vacuum or atmospheric pressure. A vent valve
closes the EVAP system to atmosphere, sealing the system during leak testing. The pump section
of the LDP consists of a diaphragm that moves up and down to bring air in through the air filter and
inlet check valve, and pump it out through an outlet check valve into the EVAP system.
The diaphragm is pulled up by engine vacuum, and pushed down by spring pressure, as the LDP
solenoid turns on and off. The LDP also has a magnetic reed switch to signal diaphragm position to
the PCM. When the diaphragm is down, the switch is closed, which sends a 12 V (system voltage)
signal to the PCM. When the diaphragm is up, the switch is open, and there is no voltage sent to
the PCM. This allows the PCM to monitor LDP pumping action as it turns the LDP solenoid on and
off.

Detection Pump, Evaporative System > Component Information > Specifications > Page 2897
LDP AT REST (NOT POWERED)
When the LDP is at rest (no electrical/vacuum) the diaphragm is allowed to drop down if the
internal (EVAP system) pressure is not greater than the return spring. The LDP solenoid blocks the
engine vacuum port and opens the atmospheric pressure port connected through the EVAP system
air filter. The vent valve is held open by the diaphragm. This allows the canister to see atmospheric
pressure.

Detection Pump, Evaporative System > Component Information > Specifications > Page 2898
DIAPHRAGM UPWARD MOVEMENT
When the PCM energizes the LDP solenoid, the solenoid blocks the atmospheric port leading
through the EVAP air filter and at the same time opens the engine vacuum port to the pump cavity
above the diaphragm. The diaphragm moves upward when vacuum above the diaphragm exceeds
spring force. This upward movement closes the vent valve. It also causes low pressure below the
diaphragm, unseating the inlet check valve and allowing air in from the EVAP air filter. When the
diaphragm completes its upward movement, the LDP reed switch turns from closed to open.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak
Detection Pump, Evaporative System > Component Information > Specifications > Page 2899
DIAPHRAGM DOWNWARD MOVEMENT based on reed switch input, the PCM de-energizes the
LDP solenoid, causing it to block the vacuum port, and open the atmospheric port. This connects
the upper pump cavity to atmosphere through the EVAP air filter. The spring is now able to push
the diaphragm down. The downward movement of the diaphragm closes the inlet check valve and
opens the outlet check valve pumping air into the evaporative system. The LDP reed switch turns
from open to closed, allowing the PGM to monitor LDP pumping (diaphragm up/down) activity.
During the pumping mode, the diaphragm will not move down far enough to open the vent valve
The pumping cycle is repeated as the solenoid is turned on and off. When the evaporative system
begins to pressurize, the pressure on the bottom of the diaphragm will begin to oppose the spring
pressure, slowing the pumping action. The PCM watches the time from when the solenoid is
de-energized, until the diaphragm drops down far enough for the reed switch to change from
opened to closed. If the reed switch changes too quickly, a leak may be indicated. The longer it
takes the reed switch to change state, the tighter the evaporative system is sealed. If the system
pressurizes too quickly, a restriction somewhere in the EVAP system may be indicated.
PUMPING ACTION During portions of this test, the PCM uses the reed switch to monitor
diaphragm movement. The solenoid is only turned on by the PCM after the reed switch changes
from open to closed, indicating that the diaphragm has moved down. At other times during the test,
the PCM will rapidly cycle the LDP solenoid on and off to quickly pressurize the system. During
rapid cycling, the diaphragm will not move enough to change the reed switch state. In the state of
rapid cycling, the PCM will use a fixed time interval to cycle the solenoid.

Figure 6
EVAP leak detection test sequence
When the ignition key is turned to "ON" the LDP diaphragm should be in the down position and the
LDP reed switch should be closed. If the EVAP system has residual pressure, the LDP diaphragm
may be up. This could result in the LDP reed switch being open when the key is turned to "ON" and
a P1494 fault could be set because the PCM is expecting the reed switch to be closed.
After the key is turned "ON", the PCM immediately tests the LDP solenoid circuit for electrical
faults. If a fault is detected, DTC P1495 will set, the MIL will illuminate, and the remaining EVAP
Leak Detection Test is canceled.
NOTE: If battery temperature is not within range, or if the engine coolant temperature is not within a
specified range of the battery temperature, the PCM will not run tests for DTC P1494, P1486,
P0442, P0455 and P0441. These temperature calibrations may be different between models.
FIGURE 6 SECTION 2
If DTC P1495 is not set, the PCM will check for DTC P1494. If the LDP reed switch was closed
when the key was turned to "ON", the PCM energizes the LDP solenoid for up to 8 seconds and
monitors the LDP switch. As the LDP diaphragm is pulled up by engine vacuum, the LDP reed
switch should change from closed to open. If it does not, the PCM sets a temporary fault (P1494) in
memory, and waits until the next time the Enabling Conditions are met to run the test again. If this
is again detected, P1494 is stored and the MIL is illuminated. If the problem is not detected during
the next enabling cycle, the temporary fault will be cleared.
However, if the PCM detects the reed switch open when the key is turned to "ON", the PCM must
determine if this condition is due to residual pressure in the EVAP system, or an actual fault. The
PCM stores information in memory on EVAP system purging from previous engine run or drive
cycles.
If little or no purging took place, residual pressure could be holding the LDP diaphragm up, causing
the LDP switch to be open. Since this is not a malfunction, the PCM cancels the EVAP Leak
Detection Test without setting the temporary fault.
If there was sufficient purging during the previous cycle to eliminate EVAP system pressure, the
PCM judges that this is a malfunction and sets a temporary fault in memory. The next time that the
Enabling Conditions are met, the test will run again. If the fault is again detected, the MIL will

Dodge Workshop Manuals > Powertrain Management > Emission Control Systems > Evaporative Emissions System > Leak
Detection Pump, Evaporative System > Component Information > Specifications > Page 2902
illuminate and DTC 1494 will be stored. If the fault is not detected, the temporary fault will be
cleared.
FIGURE 6 SECTION 3
If no fault has been detected so far, the PCM begins testing for possible blockage in the EVAP
system between the LDP and the fuel tank. This is done by monitoring the time required for the
LDP to pump air into the EVAP system during two to three pump cycles. If no blockage is present,
the LDP diaphragm is able to quickly pump air out of the LDP each time the PCM turns oft the LDP
solenoid. If a blockage is present, the PCM detects that the LDP takes longer to complete each
pump cycle. If the pump cycles take longer than expected (approximately 6 to 10 seconds) the
PCM will suspect a blockage. On the next drive when Enabling Conditions are met, the test will run
again. If blockage is again detected, P1486 is stored, and the MIL is illuminated.
FIGURE 6 SECTION 4
After the LDP blockage tests are completed, the PCM then tests for EVAP system leakage. First,
the PCM commands the LDP to rapidly pump for 20 to 50 seconds (depending on fuel level) to
build pressure in the EVAP system. This evaluates the system J18-24-0 to see if it can be
sufficiently pressurized. This evaluation (rapid pump cycling) may occur several times prior to leak
checking. The LDP reed switch does not close and open during rapid pumping because the
diaphragm does not travel through its full range during this part of the test.
FIGURE 6 SECTION 5
Next, the PCM performs one or more test cycles by monitoring the time required for the LDP reed
switch to close (diaphragm to drop) after the LDP solenoid is turned off.
If the switch does not close, or closes after a long delay, it means that the system does not have
any significant leakage and the EVAP Leak Detection Test is complete.
However, if the LDP reed switch closes quickly, there may be a leak or the fuel level may be low
enough that the LDP must pump more to finish pressurizing the EVAP system. In this case, the
PCM will rapidly pump the LDP again to build pressure in the EVAP system, and follow that by
monitoring the time needed for several LDP test cycles. This process of rapid pumping followed by
several LDP test cycles may repeat several times before the PCM judges that a leak is present.
When leaks are present, the LDP test cycle time will be inversely proportional to the size of the
leak. The larger the leak, the shorter the test cycle time. The smaller the leak, the longer the test
cycle time. DTC's may be set when a leak as small as 0.5 mm (0.020") diameter is present.
If the system detects a leak, a temporary fault will be stored in PCM memory. The time it takes to
detect a .020, .040, or Large leak is based on calibrations that vary from model to model. The
important point to remember is if a leak is again detected on the next EVAP Leak Detection Test,
the MIL will illuminate and a DTC will be stored based on the size of leak detected. If no leak is
detected during the next test, the temporary fault will be cleared.
DIAGNOSTIC TIPS
During diagnosis, you can compare the LDP solenoid activity with the monitor sequence in Figure
6. If the PCM detects a problem that could set a DTC, the testing is halted and LDP solenoid
activity will stop. As each section of the test begins, it indicates that the previous section passed
successfully. By watching to see which tests complete, you can see if any conditions are present
that the PCM considers abnormal.
For example, if the LDP solenoid is energized for the test cycles to test for blockage (P1486), it
means that the LDP has already passed its test for P1494. Then, if the PCM detects a possible
blockage, it will set a temporary fault without turning on the MIL and continue the leak portion of the
test. However, the PCM will assume that the system is already pressurized and skip the rapid
pump cycles.
Always diagnose leaks, if possible, before disconnecting connections. Disconnecting connections
may mask a leak condition.
Keep in mind that if the purge solenoid seat is leaking, it could go undetected since the leak would
end up in the intake manifold. Disconnect the purge solenoid at the manifold when leak checking.
In addition, a pinched hose fault (P1486) could set if the purge solenoid does not purge the fuel
system properly (blocked seat). The purge solenoid must vent the fuel system prior to the LDP
system test. If the purge solenoid cannot properly vent the system the LDP cannot properly
complete the test for P1486 and this fault can set due to pressure being in the EVAP system during
the test sequence.
Multiple actuation's of the DRB Ill® Leak Detection Pump (LDP) Monitor Test can hide a 0.020 leak
because of excess vapor generation. Additionally, any source for additional vapor generation can
hide a small leak in the EVAP system. Excess vapor generation can delay the fall of the LDP
diaphragm thus hiding the small leak. An example of this condition could be bringing a cold vehicle
into a warm shop for testing or high ambient temperatures.
Fully plugged and partially plugged underhood vacuum lines have been known to set MIL
conditions. P1494 and P0456 can be set for this reason. Always, thoroughly, check plumbing for
pinches or blockage before condemning components.
TEST EQUIPMENT
The Evaporative Emission Leak Detector (EELD) Miller Special Tool 8404 is capable of visually
detecting leaks in the evaporative system and will take

Detection Pump, Evaporative System > Component Information > Specifications > Page 2903
the place of the ultrasonic leak detector 6917A. The EELD utilizes shop air and a smoke generator
to visually detect leaks down to 0.020 or smaller. The food grade oil used to make the smoke
includes an UV trace dye that will leave telltale signs of the leak under a black light. This is helpful
when components have to be removed to determine the exact leak location. For detailed test
instructions, follow the operators manual packaged with the EELD.
IMPORTANT
Be sure that the PCM has the latest software update. Reprogram as indicated by any applicable
Technical Service Bulletin. After LDP repairs are completed, verify the repair by running the DRB
Ill® Leak Detection Pump (LDP) Monitor Test as described in Technical Service Bulletin 18-12-99.

Fig. 8 PCV System Hoses/Tubes
- two interconnected breathers threaded into the rear of each cylinder head.
- tubes and hose to connect the system components.
The PCV system operates by engine intake manifold vacuum. Filtered air is routed into the
crankcase through the air cleaner hose and crankcase breathers. The metered air, along with
crankcase vapors, are drawn through the PCV valve and into a passage in the intake manifold. The
PCV system manages crankcase pressure and meters blow-by gases to the intake system,
reducing engine sludge formation.
The PCV valve contains a spring loaded plunger. This plunger meters the amount of crankcase
vapors routed into the combustion chamber based on intake manifold vacuum.

TYPICAL PCV valves are shown in, and.
When the engine is not operating, or during an engine pop-back, the spring forces the plunger back
against the seat. This will prevent vapors from flowing through the valve.
During periods of high manifold vacuum, such as idle or cruising speeds, vacuum is sufficient to
completely compress spring. It will then pull the plunger to the top of the valve. In this position there
is minimal vapor flow through the valve.
During periods of moderate manifold vacuum, the plunger is only pulled part way back from inlet.
This results in maximum vapor flow through the valve.

Fuel Injector: Description and Operation
Fig. 20 Fuel Injector - Typical
An individual fuel injector (Fig. 20) is used for each individual cylinder.
The top (fuel entry) end of the injector (Fig. 20) is attached into an opening on the fuel rail.
The fuel injectors are electrical solenoids. The injector contains a pintle that closes OFF an orifice
at the nozzle end. When electric current is supplied to the injector, the armature and needle move a
short distance against a spring, allowing fuel to flow out the orifice. Because the fuel is under high
pressure, a fine spray is developed in the shape of a pencil stream. The spraying action atomizes
the fuel, adding it to the air entering the combustion chamber.
The nozzle (outlet) ends of the injectors are positioned into openings in the intake manifold just
above the intake valve ports of the cylinder head. The engine wiring harness connector for each
fuel injector is equipped with an attached numerical tag (INJ 1, INJ 2 etc.). This is used to identify
each fuel injector.
The injectors are energized individually in a sequential order by the powertrain control module
(PCM). The PCM will adjust injector pulse width by switching the ground path to each individual
injector ON and OFF. Injector pulse width is the period of time that the injector is energized. The
PCM will adjust injector pulse width based on various inputs it receives.
Battery voltage is supplied to the injectors through the ASD relay. The PCM determines injector
pulse width based on various inputs.
PCM Output
The nozzle ends of the injectors are positioned into openings in the intake manifold just above the
intake valve ports of the cylinder head. The engine wiring harness connector for each fuel injector
is equipped with an attached numerical tag (INJ 1, INJ 2 etc.). This is used to identify each fuel
injector with its respective cylinder number.
The injectors are energized individually in a sequential order by the Powertrain Control Module
(PCM). The PCM will adjust injector pulse width by switching the ground path to each individual
injector ON and OFF. Injector pulse width is the period of time that the injector is energized. The
PCM will adjust injector pulse width based on various inputs it receives.
Battery voltage (12 volts +) is supplied to the injectors through the ASD relay. The ASD relay will
shutdown the 12 volt power source to the fuel injectors if the PCM senses the ignition is ON, but
the engine is not running. This occurs after the engine has not been running for approximately 1.8
seconds.
The PCM determines injector on-time (pulse width) based on various inputs.

Fuel Injector: Testing and Inspection
To perform a complete test of the fuel injectors and their circuitry, use the DRB scan tool and refer
to the appropriate Powertrain Diagnostics Procedures. To test the injector only, refer to the
following:
Disconnect the fuel injector wire harness connector from the injector. The injector is equipped with
2 electrical terminals (pins). Place an ohmmeter across the terminals. Resistance reading should
be approximately 12 ohms ± 1.2 ohms at 20 °C (68 °F).

FUEL FILTER/PRESSURE REGULATOR
A combination fuel filter and fuel pressure regulator (Fig. 2) is used on all engines. It is located on
the top of the fuel pump module. A separate frame mounted fuel filter is not used with any engine.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for
extended service. They do not require normal scheduled maintenance. Filters should only be
replaced if a diagnostic procedure indicates to do so.
Fuel Pressure Regulator Operation: The pressure regulator is a mechanical device that is not
controlled by engine vacuum or the powertrain control module (PCM).
The regulator is calibrated to maintain fuel system operating pressure of approximately 339 kPa ±
34 kPa (49.2 psi ± 5 psi) at the fuel injectors. It contains a diaphragm, calibrated springs and a fuel
return valve. The internal fuel filter (Fig. 2) is also part of the assembly.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Fuel Delivery and Air Induction > Fuel Pressure Regulator >
Component Information > Locations > Page 2983
Fuel is supplied to the filter/regulator by the electric fuel pump through an opening tube at the
bottom of filter/regulator (Fig. 2).
The regulator acts as a check valve to maintain some fuel pressure when the engine is not
operating. This will help to start the engine. A second check valve is located at the outlet end of the
electric fuel pump. Refer to Fuel Pump Description and Operation for more information. Also refer
to the Fuel Pressure Leak Down Test and the Fuel Pump Pressure Tests.
If fuel pressure at the pressure regulator exceeds approximately 49.2 psi, an internal diaphragm
opens and excess fuel pressure is routed back into the tank through the bottom of pressure
regulator.
Both fuel filters (at bottom of fuel pump module and within fuel pressure regulator) are designed for
extended service. They do not require normal scheduled maintenance. Filters should only be
replaced if a diagnostic procedure indicates to do so.

The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM. Whenever the ignition key
is turned ON, the electric fuel pump will operate. But, the PCM will shutdown the ground circuit to
the fuel pump relay in approximately 1-3 seconds unless the engine is operating or the starter
motor is engaged.

Fuel Gauge Sender: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To
test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump
module. Refer to Fuel Pump Module Removal/installation for procedures. Measure the resistance
across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6%.
With float in down position, resistance should be 270 ohms ± 6%.

Idle Air Control (IAC) Motor: Description and Operation
The IAC stepper motor is mounted to the throttle body, and regulates the amount of air bypassing
the control of the throttle plate. As engine loads and ambient temperatures change, engine rpm
changes. A pintle on the IAC stepper motor protrudes into a passage in the throttle body,
controlling air flow through the passage. The IAC is controlled by the Powertrain Control Module
(PCM) to maintain the target engine idle speed.
At idle, engine speed can be increased by retracting the IAC motor pintle and allowing more air to
pass through the port, or it can be decreased by restricting the passage with the pintle and
diminishing the amount of air bypassing the throttle plate.
The IAC is called a stepper motor because it is moved (rotated) in steps, or increments. Opening
the IAC opens an air passage around the throttle blade which increases RPM.
The PCM uses the IAC motor to control idle speed (along with timing) and to reach a desired MAP
during decel (keep engine from stalling).
The IAC motor has 4 wires with 4 circuits. Two of the wires are for 12 volts and ground to supply
electrical current to the motor windings to operate the stepper motor in one direction. The other 2
wires are also for 12 volts and ground to supply electrical current to operate the stepper motor in
the opposite direction.
To make the IAC go in the opposite direction, the PCM just reverses polarity on both windings. If
only 1 wire is open, the IAC can only be moved 1 step (increment) in either direction. To keep the
IAC motor in position when no movement is needed, the PCM will energize both windings at the
same time. This locks the IAC motor in place.
In the IAC motor system, the PCM will count every step that the motor is moved. This allows the
PCM to determine the motor pintle position. If the memory is cleared, the PCM no longer knows the
position of the pintle. So at the first key ON, the PCM drives the IAC motor closed, regardless of
where it was before. This zeros the counter, From this point the PCM will back out the IAC motor
and keep track of its position again.
When engine rpm is above idle speed, the IAC is used for the following:
- OFF-idle dashpot (throttle blade will close quickly but idle speed will not stop quickly)
- Deceleration air flow control
- A/C compressor load control (also opens the passage slightly before the compressor is engaged
so that the engine rpm does not dip down when the compressor engages)
- Power steering load control
The PCM can control polarity of the circuit to control direction of the stepper motor.
IAC Stepper Motor Program: The PCM is also equipped with a memory program that records the
number of steps the IAC stepper motor most recently advanced to during a certain set of
parameters. For example: The PCM was attempting to maintain a 1000 rpm target during a cold
start-up cycle. The last recorded number of steps for that may have been 125. That value would be
recorded in the memory cell so that the next time the PCM recognizes the identical conditions, the
PCM recalls that 125 steps were required to maintain the target. This program allows for greater
customer satisfaction due to greater control of engine idle.
Another function of the memory program, which occurs when the power steering switch (if
equipped), or the A/C request circuit, requires that the IAC stepper motor control engine rpm, is the
recording of the last targeted steps into the memory cell. The PCM can anticipate A/C compressor
loads. This is accomplished by delaying compressor operation for approximately 0.5 seconds until
the PCM moves the IAC stepper motor to the recorded steps that were loaded into the memory
cell. Using this program helps eliminate idle-quality changes as loads change. Finally, the PCM
incorporates a "No-Load" engine speed limiter of approximately 1800 - 2000 rpm, when it
recognizes that the TPS is indicating an idle signal and IAC motor cannot maintain engine idle.
A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle
plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are
controlled by the IAC motor through the PCM.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Fuel Pump Relay: Description and Operation
The 5-pin, 12-volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the
label on the PDC cover for relay location.
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump
relay. The fuel pump relay is energized by first applying battery voltage to it when the ignition key is
turned ON, and then applying a ground signal to the relay from the PCM. Whenever the ignition key
is turned ON, the electric fuel pump will operate. But, the PCM will shutdown the ground circuit to
the fuel pump relay in approximately 1-3 seconds unless the engine is operating or the starter
motor is engaged.

Auto Shut Down (ASD) Relay: Description and Operation
AUTO SHUT DOWN RELAY
PCM Output The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power
Distribution Center (PDC). Refer to label on PDC cover for relay location.
The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With
certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements.
The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module
(PCM). The PCM operates the ASD relay by switching its ground circuit ON and OFF.
The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be
de-activated by the PCM if: the ignition key is left in the ON position. This is if the engine has not been running for
approximately 1.8 seconds.
- there is a crankshaft position sensor signal to the PCM that is lower than pre-determined values.
ASD Sense - PCM Input A 12 volt signal at this input indicates to the PCM that the ASD has been
activated. The relay is used to connect the oxygen sensor heater element, ignition coil and fuel
injectors to 12 volt + power supply.
This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module
(PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic
Trouble Code (DTC).

Throttle Position Sensor: Description and Operation
The 3-wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the
throttle blade.
The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

Throttle Body: Description and Operation
The throttle body is located on the intake manifold. Fuel does not enter the intake manifold through
the throttle body. Fuel is sprayed into the manifold by the fuel injectors.
Filtered air from the air cleaner enters the intake manifold through the throttle body. The throttle
body contains an air control passage controlled by an Idle Air Control (IAC) motor. The air control
passage is used to supply air for idle conditions. A throttle valve (plate) is used to supply air for
above idle conditions.
Certain sensors are attached to the throttle body. The accelerator pedal cable, speed control cable
and transmission control cable (when equipped) are connected to the throttle body linkage arm.
A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle
plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are
controlled by the PCM.

The TPS is a 3-wire variable resistor that provides the Powertrain Control Module (PCM) with an
input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is
connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance
(output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the
PCM) represents the throttle blade position. The PCM receives an input signal voltage from the
TPS. This will vary in an approximate range of from 0.26 volts at minimum throttle opening (idle), to
4.49 volts at wide open throttle. Along with inputs from other sensors, the PCM uses the TPS input
to determine current engine operating conditions. In response to engine operating conditions, the
PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This
information is needed to assist in performing the following calculations:
- Ignition timing advance
- Fuel injection pulse-width
- Idle (learned value or minimum TPS)
- OFF-idle (0.06 volt)
- Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
- Deceleration fuel lean out
- Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
- A/C WOT cutoff (certain automatic transmissions only)

This engine uses 8 dedicated, and individually fired coil for each spark plug. Each coil is mounted
directly to the top of each spark plug.
Battery voltage is supplied to the 8 ignition coils from the ASD relay. The Powertrain Control
Module (PCM) opens and closes each ignition coil ground circuit at a determined time for ignition
coil operation.
Base ignition timing is not adjustable. By controlling the coil ground circuit, the PCM is able to set
the base timing and adjust the ignition timing advance. This is done to meet changing engine
operating conditions.
The ignition coil is not oil filled. The windings are embedded in an epoxy compound. This provides
heat and vibration resistance that allows the ignition coil to be mounted on the engine.

Spark Plug: Description and Operation
This engine are equipped with "fired in suppressor seal" type spark plugs using a copper core
ground electrode.
Because of the use of an aluminum cylinder head on this engine, spark plug torque is very critical.
To prevent possible pre-ignition and/or mechanical engine damage, the correct type/heat
range/number spark plug must be used.
Remove the spark plugs and examine them for burned electrodes and fouled, cracked or broken
porcelain insulators. Keep plugs arranged in the order in which they were removed from the
engine. A single plug displaying an abnormal condition indicates that a problem exists in the
corresponding cylinder. Replace spark plugs at the intervals recommended in Lubrication and
Maintenance.
Spark plugs that have low mileage may be cleaned and reused if not otherwise defective, carbon or
oil fouled. Also refer to Spark Plug Conditions.
CAUTION: Never use a motorized wire wheel brush to clean the spark plugs. Metallic deposits will
remain on the spark plug insulator and will cause plug misfire.

Spark Plug: Testing and Inspection
SPARK PLUG CONDITIONS
Fig. 20 Normal Operation And Cold (Carbon) Fouling
Normal Operating The few deposits present on the spark plug will probably be light tan or slightly
gray in color. This is evident with most grades of commercial gasoline. There will not be evidence
of electrode burning. On this engine gap growth will not average more than approximately 0.0015
in per 3200 km (2000 miles) of operation. Spark plugs that have normal wear can usually be
cleaned, have the electrodes filed, have the gap set and then be installed.
Some fuel refiners in several areas of the United States have introduced a Manganese Additive
(MMT) for unleaded fuel. During combustion, fuel with MMT causes the entire tip of the spark plug
to be coated with a rust colored deposit. This rust color can be misdiagnosed as being caused by
coolant in the combustion chamber. Spark plug performance may be affected by MMT deposits.
Cold Fouling/carbon Fouling Cold fouling is sometimes referred to as carbon fouling. The deposits
that cause cold fouling are basically carbon. A dry, black deposit on one or two plugs in a set may
be caused by sticking valves or defective spark plug cables. Cold (carbon) fouling of the entire set
of spark plugs may be caused by a clogged air cleaner element or repeated short operating times
(short trips).
Wet Fouling Or Gas Fouling A spark plug coated with excessive wet fuel or oil is wet fouled. In
older engines, worn piston rings, leaking valve guide seals or excessive cylinder wear can cause
wet fouling. In new or recently overhauled engines, wet fouling may occur before break-in (normal
oil control) is achieved. This condition can usually be resolved by cleaning and reinstalling the
fouled plugs.

Fig. 21 Oil Or Ash Encrusted
Oil Or Ash Encrusted If one or more spark plugs are oil or oil ash encrusted, evaluate engine
condition for the cause of oil entry into that particular combustion chamber.
Fig. 22 Electrode Gap Bridging
Electrode Gap Bridging Electrode gap bridging may be traced to loose deposits in the combustion
chamber. These deposits accumulate on the spark plugs during continuous stop-and-go driving.
When the engine is suddenly subjected to a high torque load, deposits partially liquefy and bridge
the gap between electrodes. This short circuits the electrodes. Spark plugs with electrode gap
bridging can be cleaned using standard procedures.

Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information >
Specifications > Page 3174
Fig. 23 Scavenger Deposits
Scavenger Deposits Fuel scavenger deposits may be either white or yellow. They may appear to
be harmful, but this is a normal condition caused by chemical additives in certain fuses. These
additives are designed to change the chemical nature of deposits and decrease spark plug misfire
tendencies. Notice that accumulation on the ground electrode and shell area may be heavy, but the
deposits are easily removed. Spark plugs with scavenger deposits can be considered normal in
condition and can be cleaned using standard procedures.
Fig. 24 Chipped Electrode Insulator
Chipped Electrode Insulator A chipped electrode insulator usually results from bending the center
electrode while adjusting the spark plug electrode gap. Under certain conditions, severe detonation
can also separate the insulator from the center electrode. Spark plugs with this condition must be
replaced.

Dodge Workshop Manuals > Powertrain Management > Ignition System > Spark Plug > Component Information >
Specifications > Page 3175
Fig. 25 Preignition Damage
Preignition Damage Preignition damage is usually caused by excessive combustion chamber
temperature. The center electrode dissolves first and the ground electrode dissolves somewhat
latter. Insulators appear relatively deposit free. Determine if the spark plug has the correct heat
range rating for the engine. Determine if ignition timing is over advanced or if other operating
conditions are causing engine overheating. (The heat range rating refers to the operating
temperature of a particular type spark plug. Spark plugs are designed to operate within specific
temperature ranges. This depends upon the thickness and length of the center electrodes porcelain
insulator.)
Fig. 26 Spark Plug Overheating
Spark Plug Overheating Overheating is indicated by a white or gray center electrode insulator that
also appears blistered. The increase in electrode gap will be considerably in excess of 0.001 inch
per 2000 miles of operation. This suggests that a plug with a cooler heat range rating should be
used. Over advanced ignition timing, detonation and cooling system malfunctions can also cause
spark plug overheating.

REMOVAL
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides
of shield for removal. Each shield is slotted to allow for compression and removal. To install the
shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
In this engine: Each individual spark plug is located under each ignition coil. Each individual ignition
coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation.
1. In this engine: Prior to removing spark plug, spray compressed air around base of ignition coil at
cylinder head. This will help prevent foreign
material from entering combustion chamber.
2. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. If
equipped with this engine, also check condition of
coil O-ring and replace as necessary.
3. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
The plugs may be cleaned using commercially available spark plug cleaning equipment. After
cleaning, file center electrode flat with a small point file or jewelers file before adjusting gap.
CAUTION: Never use a motorized wire wheel brush to clean spark plugs. Metallic deposits will
remain on spark plug insulator and will cause plug misfire.
INSTALLATION
CAUTION: This engine is equipped with copper core ground electrode spark plugs. They must be
replaced with the same type/number spark plug as the original. If another spark plug is substituted,
pre-ignition will result.
Special care should be taken when installing spark plugs into the cylinder head spark plug wells.
Be sure the plugs do not drop into the plug wells as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in
a change in the spark plug gap or a cracked porcelain insulator.
1. Start the spark plug into the cylinder head by hand to avoid cross threading. 2. In this engine:
Tighten spark plugs to 27 Nm (20 ft. lbs.) torque. 3. In this engine: Before installing coil(s), check
condition of coil O-ring and replace as necessary. To aid in coil installation, apply silicone to coil
O-ring.
4. In this engine: Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

Overdrive Indicator Lamp: Description and Operation
OVERDRIVE OFF INDICATOR
An overdrive OFF indicator is standard equipment on all instrument clusters. However, on vehicles
not equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The overdrive OFF indicator consists of the text "O/D OFF", which appears in the lower
portion of the electronic gear selector indicator Vacuum Fluorescent Display (VFD). The VFD is
part of the cluster electronic circuit board, and is visible through a cutout located in the lower right
corner of the cluster overlay. The dark lens of the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "O/D OFF" appears in an amber color and at the same
lighting level as the gear selector indicator information when it is illuminated by the instrument
cluster electronic circuit board. The overdrive OFF indicator is serviced as a unit with the VFD in
the instrument cluster.
The overdrive OFF indicator gives an indication to the vehicle operator when the OFF position of
the overdrive OFF switch has been selected, disabling the electronically controlled overdrive
feature of the automatic transmission. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The overdrive OFF indicator receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the indicator will always be OFF when the ignition switch
is in any position except ON or Start. The indicator only illuminates when it is switched to ground by
the instrument cluster circuitry. The instrument cluster will turn ON the overdrive OFF indicator for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the overdrive OFF indicator
is illuminated for about two seconds as a bulb test.
- Overdrive OFF Lamp-ON Message - Each time the cluster receives an overdrive OFF lamp-ON
message from the PCM indicating that the OFF position of the overdrive OFF switch has been
selected, the overdrive OFF indicator will be illuminated. The indicator remains illuminated until the
cluster receives an overdrive OFF lamp-OFF message from the PCM, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the overdrive OFF indicator
will be turned ON, then OFF again during the VFD portion of the test to confirm the functionality of
the VFD, and again during the bulb check portion of the test to confirm the functionality of the
cluster control circuitry.
The PCM continually monitors the overdrive OFF switch to determine the proper outputs to the
automatic transmission. The PCM then sends the proper overdrive OFF lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the overdrive OFF indicator or the
instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT/CLUSTER DIAGNOSIS AND TESTING). For proper diagnosis of the overdrive control system, the PCM, the
PCI data bus, or the message inputs to the instrument cluster that control the overdrive OFF
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator lamp is standard equipment on all instrument clusters.
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control Module <--> [Control Module, A/T] >
Component Information > Diagrams > Diagram Information and Instructions > Page 3258
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control Module <--> [Control Module, A/T] >
Component Information > Diagrams > Diagram Information and Instructions > Page 3259
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Component Information > Diagrams > Diagram Information and Instructions > Page 3260
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control Module <--> [Control Module, A/T] >
Component Information > Diagrams > Diagram Information and Instructions > Page 3261
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Transmission Control Module: Description and Operation
Fig. 13 Transmission Control Module Location
The Transmission Control Module (TCM) is located in the engine compartment on the right
(passenger) side and is mounted to the radiator core support (Fig. 13).
The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control Module <--> [Control Module, A/T] >
Component Information > Diagrams > Page 3280
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > Transmission Control Systems > Relays and Modules Transmission and Drivetrain > Relays and Modules - A/T > Transmission Control Module <--> [Control Module, A/T] >
Component Information > Diagrams > Page 3281
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3381
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3385
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3386
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3392
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC
Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

CUMMINS
Types:
^ CM551 and CM84x series
NOTE:
Cummins flash reprogrammable PCMs are used on 1998.5 and newer Dodge Trucks.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine
Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery
Specifics:
Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.
NGC
Types:

Information > Technical Service Bulletins > All Technical Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3394
^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

DISCUSSION:
NOTE:
Many of the reasons a flash reprogramming procedure may not complete are documented in this
service bulletin, but if you are constantly having issues performing the flash reprogramming
procedure using a specific DRBIII(R), it is suggested you send the DRBIII(R) in question to
SPX/Miller Special Tools for service.
Occasionally a flash update procedure may not complete properly and/or the diagnostic equipment
may lock up or become disconnected during the procedure. Flash Reprogramming is a "CRITICAL
PROCESS"; an error may result in a no-start/failed control module. Most modules, encountering an
interruption or failure while reprogramming, are recoverable; a recoverable module is not covered
under the provisions of the warranty.
This service bulletin covers items that may cause this condition, a process to restart the flash
procedure, and miscellaneous information that will help prevent needless replacement of control
modules.
GENERAL: Flash Reprogramming is only authorized by a specific SERVICE BULLETIN, or
RECALL.
Review the entire Service Bulletin/Recall prior to performing a flash reprogramming update. Often
other parts may need to be serviced, replaced, or tested, prior to flash reprogramming, and ARE
REQUIRED as part of completing the Service Bulletin/Recall.
When flashing a Powertrain Control Module (PCM) or Transmission Control Module (TCM) there
are other legal requirements with labeling issues that are included in those service bulletins.
Other non-emission related modules, such as instrument clusters and Body Control Modules
(BCMs) do not require labels.
FLASH REPROGRAMMING SEQUENCE OF EVENTS
The process of flash reprogramming is similar to flashing the BIOS on a Personal Computer.
Interruptions, voltage problems, and a variety of other outside interactions can potentially interfere
with the process. This document seeks to provide information to minimize problems associated
with vehicle control module flash reprogramming. The description that follows is for most PCMs
and some TCMs. Other modules use different initiation procedures.
The process starts by selecting an update from the TechCONNECT Client or ISIS and then
"loading" that update into the DRBIII(R). Once the flash reprogramming update is loaded into the
DRBIII(R), and before the flash reprogramming begins, the DRBIII(R) verifies that the update
loaded from the TechCONNECT Client or ISIS is the proper update for the module. This is done
using part number supersedence. This verification occurs only if an update is required, available
(on the TechCONNECT Client or ISIS) and has been selected for programming.
^ The module is then placed into "Boot Strap" programming mode by the DRBIII(R). This module
mode gives the DRBIII(R) permission and the ability to proceed with the flash reprogramming
session.
^ Next, the current part number, which resides in the module's flash memory, is stored in a "Safe
Memory" location within the module. This memory location is not affected by flash memory erasure
and reprogramming, which are to follow.
^ Once the part number is safely stored, the flash memory in the control module is erased. From
this point forward any interruption in the flash process,
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3428
will result in a Non-Responsive module (NR). A NR module is a module that is either partially
erased or partially programmed.
^ After erasure, the actual reprogramming procedure starts, and the update software is
programmed into the flash memory within the module.
^ When reprogramming is completed, the flash memory is verified through an internal process in
the DRBIII(R) using a "Check Sum". This value is compared against another value that represents
what should be in memory and when matched, verifies successful reprogramming.
^ Next, a DRBIII(R) prompt is displayed instructing that the ignition switch be turned OFF. The
module exits the "Boot Strap" mode when the switch is turned off.
^ After a slight pause, the DRBIII(R) will prompt for the ignition switch to be turned ON. The
DRBIII(R) then reads the new part number in flash memory (along with a new computer program
the new part number is placed into the module's memory). If the new part number matches the
expected part number, the flash reprogramming session has completed successfully.
SOFTWARE VERSIONS MUST BE CURRENT
Before attempting a flash reprogramming session using the TechCONNECT Client, make sure you
have the most current DRBIII(R) software installed.
To verify whether your DRBIII(R) software is current, check the upper right-hand corner of the
TechCONNECT Client screen for DRBIII(R) Available Version, DRBIII(R) Current Version.
Often, because of multiple DRBIII(R)s in the shop, not all will get updated on a timely manner. The
installed DRBIII(R) software version can generally be found at the bottom center of most screens.
Alternately the version can be checked by pressing 6, 2, 5 from the DRBIII(R) Main Menu and
comparing it to what is available from a current TechCONNECT Client as described above.
If the TechCONNECT Client is current and the DRBIII(R) is not, it may be due to the fact that the
TechCONNECT Client does not force DRBIII(R) updates for "minor" revisions. Changes and new
support are added to the Vehicle Flash application on "minor" revisions on a regular basis. This is
why your TechCONNECT Client and DRBIII(R) must have the LATEST software revisions
installed.
DO NOT PASS on the option for updating to a "minor" revision!
Major updates require the DRBIII(R) to be updated prior to allowing any flash programming.
DRBIII(R) CABLES
A NEW DRBIII(R) cable was released as an Essential Service Tool! CH7000A - 8 ft.
Cable, DRBIII(R) to OBDII (J1962) DLC Connector.
CH7000A is the required cable for ALL flash reprogramming. The older CH7000 cable can be used
for diagnostics ONLY. One (1) cable was shipped to all dealerships. Easily identified, the correct
cable has a RED connector, which plugs into the DRBIII(R).
The cable modification enhances the DRBIII(R) communication capabilities when dealing with the
flash requirements of certain controllers/ECUs affected in part by the recent changes in DLC
connector configurations.
The new cable is required for ALL flash reprogramming sessions, and can be used wherever the
previous CH700017001 cables were used.
While not recommended for flash reprogramming usage, if you require a longer cable, there is also
a 12-foot cable released under pin CH7001A
The production of the previous CH700017001 cables has ceased. All orders placed will be
superseded to part number CH7000A/CH7001A.

NOTE:
Consider all cables wear items. Always inspect for worn, damaged cables, connectors that are
damaged or do not lock securely, and all mating connections including checking for corrosion on
the pins. REPLACE ALL suspect cables. Do not use worn or damaged cables when flash
reprogramming.
Failure to use the new cable or to use a damaged cable often results in failed flash reprogramming
sessions.
The 2 door Sebring, Stratus, and Avenger coupes (supplied by MMC) generally use the CH7O1O
cable (Pre-OBDII MMC vehicles will use the CH7005 cable).
TechCONNECT CABLE (GPIB)
Replace any suspect GPIB cable.
The GPIB cable provides the connection between TechCONNECT Client and the DRBIII(R).
This cable is used by the TechCONNECT Client for vehicle part number reads and to send update
files to the DRBIII(R).
Inspect this cable for loose connections, damaged connectors or terminals, and wear and tear. If
this cable becomes disconnected during a flash session, you may have to reload the update file
that you selected on the TechCONNECT Client.
TROUBLESHOOTING CONNECTIVITY OF THE DRBIII(R) UNIT TO THE TechCONNECT
APPLICATION.
1. Turn-on the power to the DRBIII(R) unit.
2. Select option 2 "Connect to TechCONNECT" and press Enter.
3. Attach the male mini D-shell amphenol GPIB connector of the new DRBIII(R) cable (part number
CH7035B) to the DRBIII(R) unit.
4. Insure that the larger female D-shell amphenol GPIB connector of the new DRBIII(R) cable is
properly attached to the male D-shell amphenol GPIB connector on the GPIB-USB-B protocol
converter, (part number CHGPIB-B).
5. Attach the USB cable from the GPIB-USB-B protocol converter to one of the USB ports on the
rear panel of the client CPU.
6. When the cable is attached to the USB port of the CPU for the first time, Windows 2000 will
detect the device and install software for it. Please wait for 25-30 seconds to complete the
installation.

ISIS NULL MODEM CABLE
Replace any suspect null modem cables.
International (ISIS), a PC-based CD program similar to TechCONNECT Client uses a null modem
cable for vehicle part number reads and to send update files to the DRBIII(R). Inspect this cable for
loose connections, damaged connectors or terminals, and wear and tear. If this cable becomes
disconnected during a flash download session, you will have to reload the update file or files.
GENERAL NOTES FOR CABLES AND VEHICLE CONNECTIONS
Consider ALL cables to be wear items.
Many successful dealers have dedicated cables devoted to "Flash ONLY".
Always have spare CH7000A, CH7010 and CH2002 GPIB or null modem cables available.
Inspect vehicle diagnostic connectors for potential problems that might cause communication
interruptions.
There are now clip repair kits available through teamPSE to replace the retaining clips for two of
these cables. To protect the DRBIII(R) from internal damage, the clips are designed to fail at above
25 lbs. of axial force. Kits are described in the table.
It is a good practice to discard cables that have damage to the pins, cuts, corrosion, or general
damage beyond the retaining clips.

These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT)
was shipped as a 2001 Essential Tool. The flash reprogramming update files will be downloaded
from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized,
there is a known condition where it may take up to 5 or more attempts for it to fully initialize and
become functional.
NOTE:
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a
FLASH SESSION IS IN-PROGRESS and must NOT be interrupted. Interrupting some flash
reprogramming sessions at critical junctures can render a module inoperative. Another user may
not realize that a flash session is in-progress and may disturb or disconnect the DRBIII(R) or do
something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the
DRBIII(R) memory. (To "Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the
same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an
area where someone might trip over or kick a cable. When setting up your DRBIII(R), insure that it
rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have
been known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to
make sure item 1. Echo on PC is set to OFF. On occasion, when Echo on PC is set to ON, flash
reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to
twenty minutes depending on the particular flash reprogramming update. Connect a battery
charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a
timer, set it for 30 minutes BEFORE starting a flash reprogramming session. This will help to
prevent unwanted resets by either the DRBIII(R) and/or the vehicle module that are caused by
voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to
ensure adequate and stable system voltages on the module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
NOTE:
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle
throughout the flash session. The DRBIII(R) is connected to the TechCONNECT Client using the
GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most
vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the
vehicle you are connected to by clicking on the "Read Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client
while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and
clicking "Download/Update" button on the TechCONNECT client.
DISCONNECTED FLASH MODE
NOTE:
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3432
This is the preferred method.
This mode allows a user to flash a vehicle without being connected to the TechCONNECT Client.
This is a popular mode for flashing in a remote area of the service garage or in a back lot.
Before you attempt to use this mode, you must configure the DRBIII(R) for the desired update(s).
To do this, you must connect the DRBIII(R) to the TechCONNECT Client using the GPIB cable and
the CH7025 cable. It is not necessary to be connected to a vehicle. The GPIB (CH7035) cable will
be used to communicate with the TechCONNECT Client (for update file downloading) while the
CH7025 cable is used to provide power to the DRBIII(R).
After making the above connections, you are able to select one or more updates that you want to
perform. These selections are made by highlighting the desired updates and then clicking on the
"Download/Update" button by selecting the DRBIII(R) option on the TechCONNECT client.
Obviously, the DRBIII(R) does not have unlimited memory. If the file size of the selected updates
exceeds 948 KB, the "DRB Space Used" indicator (at the bottom-center of the TechCONNECT
Client screen) will change color from GREEN to RED. At this point you must de-select entries until
the indicator changes color to GREEN again.
When the updates have finished downloading, you may disconnect from the TechCONNECT Client
and take the DRBIII(R) to wherever the vehicle is located. The updates will remain in DRBIII(R)
memory for 8 hours while the DRBIII(R) is without power. If the DRBIII(R) is powered up for several
minutes before the 8 hour time period has expired, the update files will remain on the DRBIII(R) for
another 8 hours without power.
To start the actual flash process, after connecting to the vehicle in Disconnected Mode, you must
press "7 - Vehicle Flash" from the Main Menu on the DRBIII(R). Step by step instruction will follow
on the DRBIII(R) display. As with Connected Flash Mode, take the necessary precautions to insure
that others are aware of the flash session and that nothing disturbs the vehicle, DRBIII(R), or
cabling while performing the flash. Remember to use a battery charger set to 14 volts or a "battery
jump box".
Pay Attention While Performing Flash Reprogram Procedures
PAY ATTENTION WHILE PERFORMING FLASH REPROGRAMMING PROCEDURES
Before downloading the flash files, double check to see if the files that you have selected are the
appropriate ones for that vehicle. Don't forget about the "Read Part Numbers From Vehicle" option
on TechCONNECT Client, this can be of great assistance when trying to flash a module. If the files
selected don't download on the first attempt, try again.
The technician should NOT leave the vehicle when flash reprogramming a module.
Again, check to make sure that all cable connections are secure and that the DRBIII(R) rests on a
stable surface. If you are using a battery charger, insure that the settings and charging times are
correct and that the battery post clamps are securely fastened.
Read, record, and erase all DTCs found on the vehicle. Read and record the module type and part
number from the module that is to be flash reprogrammed.
Some control modules are not "abort-recovery" capable. When this is true, the scan tool will
indicate so by displaying a WARNING message prior to the start of reprogramming. For these
modules it is especially important that all precautions and procedures, outlined here, are carefully
followed.
Pay special attention to DRBIII(R) screen directions relating to key cycles. Missing a "Key ON" or
"Key OFF" can cause the module to have to be reflashed again. Due to the variety of module types
and vehicle options, you can't always anticipate key prompts, so be alert and ready to respond to
DRBIII(R) instructions.
Some screens will also instruct that certain modules, connectors or fuses be disconnected or pulled
prior to the start of reprogramming and re-installed immediately after completion. Be careful not to
anticipate the steps or order of operations for reprogramming any vehicle modules. Because of the
many possible changes that occur with each new release of scan tool software, always allow the
TSB/Recall and scan tool instructions to be your guide while performing flash reprogramming.
Flash reprogramming sessions usually range from 5 to 20 minutes. If the flash session has not
completed within 25 minutes after starting a flash reprogramming update, an error has most likely
occurred (Record the message that appears on the screen when a failure occurs). If this is the
case, or if you know that the flash process was interrupted, cycle the ignition key (OFF to the
locked position, then back ON). Reset the DRBIII(R) (power down for 4 seconds and then power
up) before attempting to restart the flash process. If the module still won't respond, turn the ignition
key off, disconnect the module from the vehicle for 2 minutes, reconnect the module, turn the
ignition key to run and try to restart the flash process again.
Regardless of what mode that you are in (Connected Flash or Disconnected Flash), if you have
tried twice (2 times) unsuccessfully to do a flash recovery and ALL DRBIII(R) instructions were
followed, perform the following:
^ Cold boot the DRBIII(R). This resets memory and removes all update files from the DRBIII(R).
(Push MORE and YES buttons at the same time, then press F4).
^ Reload the flash update file from the TechCONNECT Client.
^ If it fails to complete in the connected mode, first reboot the TechCONNECT Client before
re-attempting the flash download to the DRBIII(R).

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3433
^ Proceed to reflash the module.
On vehicles that have multiple flash updates available, always complete and verify each flash
update before attempting the next one.
After all flash reprogramming is completed, read and erase all DTCs in all modules on the vehicle.
A variety of DTCs may be set, which are usually related to a loss of communication with the
module(s) being reprogrammed.
Verify the update by reading the new part number using the DRBIII(R). A good double check is to
read the part number using DRBIII(R) stand alone.
At times, other modules, wired in parallel, to the DLC connector have prevented flash
reprogramming sessions to be successful. After the failed attempt, review the appropriate wiring
diagram for the vehicle you are flash reprogramming and, with the key "OFF"; disconnect the other
modules and retry the flash. Complete the flash, turn the key "OFF" and reconnect any modules
that were disconnected. Refer to the "Programmable Modules" section later in this document for
more information.
Error Messages
ERROR MESSAGES
Block Echo/Compare Errors
Block Echo and Block Compare errors are often caused by voltage fluctuations, faulty I/O cables
(CH7OOOA, CH7005, CH7010) or faulty communication connections at the diagnostic connector.
Inspect for these conditions and review the sections on Vehicle Battery Voltage and Cable
recommendations.
Checksum Errors
Checksum Errors are generally caused by corrupt flash update files, which can be caused by
DRBIII(R) memory problems. If the DRBIII(R) has been without power for more than 8 hours, the
update files and system memory could be in a corrupted state. "Cold Boot" the DRBIII(R). (To
"Cold Boot", press the MORE and YES buttons on the DRBIII(R), at the same time. Then press
"F4"). Reload the flash update file(s) from the TechCONNECT CLIENT. If it fails to complete in the
connected mode, first reboot the TechCONNECT Client before re-attempting the flash download to
the DRBIII(R). Then re-attempt the flash reprogramming process.
Enhanced and Original Abort Recovery
ENHANCED ABORT RECOVERY
Interruptions in the flash process are one of the main reasons for failed flash sessions and
non-responsive (NR) modules. Interrupting the flash process after the erase phase has started will
leave the control module in a non-functional state.
Generally, but not always, NR modules may be recovered successfully.
Briefly, abort recovery is the process used to get a NR module back to a fully functional state with
the latest software update. The technician should be familiar with the other sections in this
document and follow all DRBIII(R) user prompts carefully.
There are two methods for abort-recovery. The newer method is called "Enhanced Abort
Recovery". This is the preferred method since the original method takes several minutes longer
and requires the correct selection of module type from a list of possible PCM's or TCM's.
Starting with Release 60.1, a new useful feature was added to the flash reprogramming application
for Engine and Transmission control modules. The DRBIII(R) "writes" the YME and Controller Type
information to a "Safe Memory" location. This method allows for rapid recovery of the module part
number and minimizes errors that could otherwise be made by selecting the wrong controller type.
It also assumes that the user will attempt abort recovery for a failed flash attempt before moving to
another vehicle with the same DRBIII(R). If you need to move to another vehicle for flash
reprogramming you must erase the saved recovery information in order to successfully perform
flash reprogramming. Be careful to match the YME information displayed on the enhanced abort
recovery screen with the vehicle and module that you are attempting to recover. If you use the
recovery file on a different vehicle and module you could damage the module.
The recovery information will be displayed on your DRBIII(R), at the start of a flash session, only if
you previously encountered a problem that prevented a flash session from completing normally. If
your prior flash session was successful, the DRBIII(R) automatically erases the recovery file so that
the flash application will not show any recovery information at the start of your next flash session.
Enhanced abort recovery features:
^ Reduces the amount of time for the Module ID process.
^ Lowers the risk of possible user mistakes by presenting the user the Year, Model, Engine, and
Controller Type.
^ Currently only applicable to Engine and Transmission flash reprogramming.
^ The enhanced abort recovery file will only be erased upon a successful flash or manually by the
user.

Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3434
^ Cold booting (simultaneously pushing MORE & YES, then F4) the DRBIII(R) will not erase the
enhanced abort recovery file, but cold booting the DRBIII(R) will still erase the flash file so it can be
reloaded.
^ The user has a choice, at the start of a flash session, whether or not to use the enhanced abort
recovery feature. If the user chooses to erase the recovery file, then the DRBIII(R) will use the
original method of abort recovery.
^ Cycling the ignition key, when prompted by the DRBIII(R), is still necessary to put the controller
into bootstrap (reprogramming) mode.
ORIGINAL ABORT RECOVERY
If the choice is made to use the original method of abort recovery, a NR module is not always able
to provide the DRBIII with ID information. In this case the technician must enter this when prompted
by the DRBIII(R). Be patient when performing this process. If the module does not respond to
standard diagnostic requests, the DRBIII(R) may take several minutes before it determines that the
engine module is in a NR state. At this point, the DRBIII(R) displays the prompt "Could not
determine engine controller type. Please select from list" along with a list of possible controller
types (if the DRBIII(R) is attempting to identify a TCM, the prompt will say "trans" instead of
"engine" and list the possible trans controller types). Because of module variations, it is important
to correctly identify the PCM/TCM type so that the correct flash procedure is used. Failure to do
this will cause further problems and may damage the module. Tables are provided below to help
identify the proper module type to select. These tables correctly identify the modules that were on
the vehicles when they were built. However, some vehicles will have module types which were
superseded to a new type when a replacement part was installed (ie: EATX4 modules replaced
with an EATX4A). Correctly identify these modules using DRBIII(R) Standalone prior to attempting
flash reprogramming.
NOTE:
When instructed to turn the key to the LOCKED position, be sure that the key is not just turned to
the OFF position. The key must be rotated to the point at which it can be removed from the ignition
switch. On most vehicles the switch is on the steering column and at this position the steering
column is LOCKED. When instructed to turn the key to the RUN position, be careful not to turn the
key past this position which may engage the starter motor. This creates electrical noise which
interferes with the flash process.
General Steps for Abort Recovery
1. Review all Tips and Techniques before continuing. Pay special attention to the section on
Preparing to Flash a controller and to the Programmable Modules section.
2. Cycle the vehicle's ignition key to the LOCKED position and back to the RUN position.
3. Reset the DRBIII(R) by disconnecting the vehicle cable from the DRBIII(R) for 4 seconds and
then reconnecting the cable.
4. Depending on where the flash session was aborted, the DRBIII(R) may require that the
technician identify the control module type that was being flash reprogrammed. Use the PCM/TCM
configuration table below as a guide. This step is not necessary if using the enhanced abort
recovery method.
5. After selecting the proper control module type or choosing enhanced abort recovery, follow the
prompts that are displayed on the DRBIII(R).
NOTE:
If an error message is displayed at this point, an incorrect module type was most likely selected. If
this occurs, start the process over.
6. If the recovery process is unsuccessful, perform the following:
a. Review the TSB/Recall notice (authorizing the flash update) and all Tips and Techniques in this
document.
b. Reboot/Restart the TechCONNECT Client.
c. "Cold Boot" the DRBIII(R). (Press the MORE and YES buttons on the DRBIII(R) at the same
time, then press F4).
d. Start this process over from item # 1. If using Disconnected Mode, the flash update will have to
be reloaded from the TechCONNECT Client or ISIS DVD.

Programmable Modules
The following pages list the various modules that have flash reprogramming capability. It does not
mean that a flash is currently available. What will be described are the module types and
variations, followed by items to note, and finally, abort recovery specifics if applicable.
Powertrain Modules - Engine and Transmission
ENGINE - POWERTRAIN CONTROL MODULE (PCM)
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Powertrain Management > PROM - Programmable Read Only Memory > Component
Information > Technical Service Bulletins > All Other Service Bulletins for PROM - Programmable Read Only Memory: >
18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3439
There are a variety of Engine (PCM) modules that are flash reprogrammable. Suggestions that are
somewhat unique to each type will have comments. Prior to reprogramming a PCM, retrieve the
module information and module type using your DRBII I®. PCM information is used by many
modules. Be sure to check DIG's before and after performing all flash reprogramming event.
The DTC's associated with flash reprogramming generally relate to "lack of communication" with
the other modules during the reprogramming session.
SBEC
Types:
SBEC, SBEC 2, SBEC 3, SBEC 3+, SBEC 3A, SBEC 3A+, and SBEC 3B
NOTE:
During recovery, if the DRBIII® is not seeing the key off, you may need to remove power (B+) to
PCM by removing fuse(s) or disconnecting the PCM. When DRBIII® states to turn key ON,
reconnect fuse or harness connection.
Abort Recovery Specifics:
^ Follow instructions on the DRBIII® for the module type. See table above.
^ Some SBEC 3A, SBEC 3A+ AND SBEC 3B may be in a state where they can not correctly
identify a key cycle. In this case a Modified Key Cycle routine is required.
This state is present when the following message is displayed on the DRBIII(R): "Can not read Part
Number. Did not see Key On or PCM/TCM Controller may not be flashable". When this occurs
restart the flash session and when prompted to turn the ignition key to the LOCKED position, pull
the fuse(s) that supply battery power to the module instead. When prompted to turn the key to the
RUN position, replace the battery supply fuse(s) instead.
JTEC
Types:
^ JTEC, JTEC+
NOTE:
Viper ALL - Roll down windows especially Coupes before attempting a flash.
NOTE:
1999 WJ JTEC with Speed Proportional Steering module. Disconnect before and reconnect after
the PCM flash reprogramming session. Also see Transmission.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
NGC
Types:
^ NGC 1, NGC 2, and NGC 3
NOTE:
There are derivatives of NGC 3 that will be significant when reprogramming and or testing. NGC
modules use one of the longest time spans for flash reprogramming (approximately 15 minutes).
The NGCI and NGC3 controllers incorporate both an engine as well as a transmission controller in
a common package. The NGC2 controller incorporates the engine controller and an Electronic
Throttle Control (ETC) module in place of the TCM. All NGC controllers can be visually identified by
noting its four (4) wiring connectors. On manual transmission applications and the NGC2, only 3
connectors may be populated with pins.
NOTE:
On certain vehicles, the ABS CAB module connector MUST be disconnected prior to performing
this Repair Procedure. The CAB module and the PCM are connected at the same diagnostic
connector pin (Pin # 9). Turn ignition switch to the OFF position, disconnect the CAB module
connector, and reprogram the PCM per the Repair Procedure. When reprogramming is complete
turn the ignition switch to the OFF position, connect the CAB module connector, and then check for
DTC's. If the PCM becomes "locked" during reprogramming because the ABS CAB module
connector was not disconnected, then the PCM may be recovered by following the procedure in
this NOTE.

Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully. Model Year 2000 and earlier vehicles have one Engine
Control Fuse to pull when prompted by the DRBIII(R). Model Year 2001 and later have two Engine
Control Fuses (one 20 Amp and one 30 Amp) to pull when prompted by the DRBIII(R). The fuse(s)
are located in the PDC and need to be pulled/removed, when prompted, for at least 10 seconds.
SIEMENS
Types:
^ SIM-70
NOTE:
The SIM-70 is currently used on BUX PL and PG vehicles with a 1.6L ONLY. Abort Recovery
Specifics:
Follow DRBIII(R) prompts carefully.
BOSCH
Types:
^ EDC15V, EDC15-C5, and EDC16
NOTE:
While there have been other Bosch modules, the EDC15V is not flash reprogrammable.
Transmission controllers are usually flashed on the vehicle (since 1996).
Technicians may set the pinion factor on "NEW" modules either before or after flash
reprogramming. Suggestions follow.
After flash reprogramming and before returning the vehicle to the customer, always perform a
"QuickLearn" to the TCM.
EATX
Types:
^ EATX, EATX 2, EATX 3, EATX 3A, EATX 3B, EATX 4, and EATX 4A
NOTE:
Table shows which TCM was installed "as-built". Often TCMs are superseded by parts and or a
service bulletin.
Abort Recovery Specifics:
^ 1999 - 2000 WJ and 2000 AN/DN using 4.7L engines the service replacement EATX4A part
numbers 56041814AD and 56028227AH currently display a P/N read failed error after the flash is
completed during PIN verification. This DOES NOT mean the flash failed. Check for the part
number using DRBIII(R) in standalone mode. This exists only for the service replacement modules
listed above. Flash reprogramming for OE modules flash and read the part number correctly.
Follow DRBIII(R) prompts carefully.
NGC
Types:

18-037-05 > Oct > 05 > Engine Controls - Flash Programming Failure Recovery > Page 3441
^ NGC1, NGC2, NGC3
NOTE:
The NGC I1and NGC 3 have the EATX/XCORE and Engine modules combined. NGC 2 does not.
Vehicles with automatic transmissions using NGC2 will use an EATX4A.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
^ 2002 DR, 2002.5 DN, 2003 AN/DN and later with NGC have shown that in some instances the
CAB controller may need to be disconnected when attempting to flash the NGC controller. (This
should only be performed if an error occurs at the very beginning of the TCM flash portion.)
SIEMENS
Types:
^ EG552
NOTE:
EGS52 is used with the A580 automatic transmission WG Grand Cherokees with a 2.7L diesel
engine (BUX), ZH Crossfire and VA Sprinter.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
JTEC
Types:
^ JTEC,JTEC+
NOTE:
Except for the 45RFE, 545RFE, and AW4 automatic transmissions, the JTEC controller also
provides transmission control functions on Dodge trucks and Jeep vehicles. Additionally, they are
used on some Cummins equipped Dodge trucks with manual and automatic transmissions.
Abort Recovery Specifics:
^ Follow DRBIII(R) prompts carefully.
PRE 1996 EATX TRANSMISSION CONTROL MODULES
Prior to 1996 there was not a vehicle SCI communication wire going to the FWD EATX controller
only to the PCM. Those vehicle TCMs only communicate to the DRBIII(R) using CCD
communications.
For these FWD vehicles, use the CH5500 kit and CH7025 DIN cable when connecting those
modules to the DRBIII(R) vehicle connector.
For 1992-1993 vehicles, the TCM modules were upgraded to MY1995 software. Because of this
you will need to use the Yellow SuperCard2, CH8361,to set pinion factor or when using a "new"
(superseded) TCM from parts as only the SuperCard2 properly sets the pinion factor on these
updated modules.
Additionally, when flashing or installing P/Ns 4796121, 4796122, 4796123, or 4796124.
The wire from cavity 49 must be removed from the TCM connector, refer to service bulletin
18-24-95.

THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 46RE TRANSMISSION BUILT
BEFORE AUGUST 01, 2000 (MDH O8O1XX).
SYMPTOM/CONDITION: The customer may complain of a Malfunction Indicator Lamp (MIL)
illumination. Upon further analysis, it is determined that the MIL is caused by Diagnostic Trouble
Code (DTC) P1740 - Torque Converter Clutch (TCC) or Overdrive Solenoid Performance. Other
than the MIL, the customer may not notice any other condition with the transmission.
This condition may be caused by an intermittent and momentary TCC disengagement condition.
The transmission valve body pressure boost valve cover plate has been revised with a larger size
orifice hole to address this condition.
DIAGNOSIS:
1. Warm the transmission to normal operating temperatures.
2. Using the DRB III(R), perform a torque converter clutch (TCC) stall test. The stall test has been
revised so that the TCC remains engaged for a period of four (4) seconds.
NOTE:
THE DRB III(R) MUST BE OPERATING AT RELEASE LEVEL 50.4 MDS2 SYSTEM CIS CD2067
OR HIGHER (AVAILABLE THE WEEK OF OCTOBER 2, 2000) IN ORDER TO PERFORM THE
REVISED TORQUE CONVERTER CLUTCH STALL TEST. DO NOT USE EARLIER VERSION
STALL TEST TO DETERMINE CONDITION OF THE TORQUE CONVERTER CLUTCH.
3. If the engine stalls as a result of the TCC stall test, then perform the Repair Procedure.
4. If the engine does not stall, as a result of the TCC stall test, then further diagnosis is required.
The technician may want to consider the following components during their additional diagnosis: a
cut or worn input shaft seals, a missing pump lock-up circuit check ball, or worn converter hub,
input shaft, reaction shaft, and pump rotor.
PARTS REQUIRED:
REPAIR PROCEDURE:
1. Clean the pressure boost valve cover plate to remove any dirt or rust inhibitor prior to installation.
The revised cover plate will have a 1.75 mm (0.069 inch) orifice hole versus a 1.22 mm (0.048
inch) orifice hole in the original plate. Make sure it is clean.
2. Using the appropriate Service Manual, Group 21 - Transmissions and Transfer Case, replace
the transmission pressure boost valve cover plate p/n

Accumulator: Description and Operation
DESCRIPTION
The accumulator (Fig. 58) is a hydraulic device that has the sole purpose of cushioning the
application of a band or clutch. The accumulator consists of a dual-land piston and a spring located
in a bore in the transmission case. The 3-4 accumulator is located in a housing attached to the side
of the valve body (Fig. 59).
OPERATION
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Accumulator, A/T >
Component Information > Description and Operation > Page 3498
Both the accumulator and the 3-4 accumulator function the same. Line pressure is directed to the
small end of the piston when the transmission is placed into a DRIVE position (Fig. 60), bottoming
it against the accumulator plate. When the 1-2 upshift occurs (Fig. 61), line pressure is directed to
the large end of the piston and then to the kickdown servo. As the line pressure reaches the
accumulator, the combination of spring pressure and line pressure forces the piston away from the
accumulator plate. This causes a balanced pressure situation, which results in a cushioned band
application. After the kickdown servo has become immovable, line pressure will finish pushing the
accumulator up into its bore. When the large end of the accumulator piston is seated in its bore, the
band or clutch is fully applied.
NOTE: The accumulator is shown in the inverted position for illustrative purposes.

INSPECTION
Inspect the accumulator piston and seal rings (Fig. 62). Replace the seal rings if worn or cut.
Replace the piston if chipped or cracked. Check condition of the accumulator inner and outer
springs (Fig. 62). Replace the springs if the coils are cracked, distorted or collapsed.

DESCRIPTION
KICKDOWN (FRONT) BAND
The kickdown, or "front", band (Fig. 63) holds the common sun gear of the planetary gear sets. The
front (kickdown) band is made of steel, and faced on its inner circumference with a friction-type
lining. One end of the band is anchored to the transmission case, and the other is acted on with a
pushing force by a servo piston. The front band is a single-wrap design (the band does not
completely encompass/ wrap the drum that it holds).
LOW/REVERSE (REAR) BAND
The low/reverse band, or "rear", band (Fig. 64) is similar in appearance and operation to the front
band. The rear band is slightly different in that it does not use a link bar, but is acted directly on by
the apply lever. This is referred to as a double-wrap band design (the drum is completely
encompassed/ wrapped by the band). The double-wrap band provides a greater holding power in
comparison to the single-wrap design.
OPERATION
KICKDOWN (FRONT) BAND The kickdown band holds the common sun gear of the planetary gear
sets by applying and holding the front clutch retainer, which is splined to the sun gear driving shell,
and in turn splined directly to the sun gear. The application of the band by the servo is typically
done by an apply lever and link bar.
LOW/REVERSE (REAR) BAND The rear band holds the rear planet carrier stationary by being
mounted around and applied to the low/reverse drum.

Three hydraulically applied multi-disc clutches are used to hold some planetary geartrain
components stationary while the input clutches drive others. The 2C, 4C, and Low/Reverse
clutches are considered holding clutches. The 2C and 4C clutches are located in the 4C
retainer/bulkhead (Fig. 64), while the Low/ Reverse clutch is located at the rear of the transmission
case (Fig. 65).
OPERATION
2C CLUTCH The 2C clutch is hydraulically applied in second gear by pressurized fluid against the
2C piston. When the 2C clutch is applied, the reverse sun gear assembly is held or grounded to the
transmission case by holding the reaction planetary carrier.
4C CLUTCH The 4C clutch is hydraulically applied in second prime and fourth gear by pressurized
fluid against the 4C clutch piston. When the 4C clutch is applied, the reaction annulus gear is held
or grounded to the transmission case.
LOW/REVERSE CLUTCH The Low/Reverse clutch is hydraulically applied in park, reverse,
neutral, and first gear, only at low speeds, by pressurized fluid against the Low/Reverse clutch
piston. When the Low/Reverse clutch is applied, the input annulus assembly is held or grounded to
the transmission case.

Three hydraulically applied input clutches are used to drive planetary components. The underdrive,
overdrive, and reverse clutches are considered input clutches and are contained within the input
clutch assembly (Fig. 66) and (Fig. 67). The input clutch assembly also contains: Input shaft
- Input hub
- Clutch retainer
- Underdrive piston
- Overdrive/reverse piston
- Overdrive hub
- Underdrive hub
OPERATION
The three input clutches are responsible for driving different components of the planetary geartrain.
UNDERDRIVE CLUTCH The underdrive clutch is hydraulically applied in first, second, second
prime, and third (direct) gears by pressurized fluid against the underdrive piston. When the
underdrive clutch is applied, the underdrive hub drives the input sun gear.
OVERDRIVE CLUTCH The overdrive clutch is hydraulically applied in third (direct) and fourth
gears by pressurized fluid against the overdrive/reverse piston. When the overdrive clutch is
applied, the overdrive hub drives the reverse carrier/input annulus assembly.
REVERSE CLUTCH The reverse clutch is hydraulically applied in reverse gear by pressurized fluid
against the overdrive/reverse piston. When the reverse clutch is applied, the reaction annulus gear
is driven.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).

3547
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Transmission Control Module: Description and Operation
Fig. 13 Transmission Control Module Location
The Transmission Control Module (TCM) is located in the engine compartment on the right
(passenger) side and is mounted to the radiator core support (Fig. 13).
The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Control
Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 3569
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Transmission Control
Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 3570
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

following chart to determine the appropriate operation expected, depending on driving conditions.

DO NOT over fill transmission beyond normal fluid level markings. Fluid foaming and transmission
damage may occur.

Fluid - A/T: Testing and Inspection Effects of Incorrect Fluid Level
EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid
pressures to be low and develop slower than normal. If the transmission is overfilled, the gears
chum the fluid into foam. This aerates the fluid and causing the same conditions occurring with a
low level. In either case, air bubbles cause fluid overheating, oxidation and varnish buildup which
interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in
fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a
leak if inspection is not careful.

Fluid - A/T: Testing and Inspection Causes of Burnt Fluid
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes. 1. Internal clutch
slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal
failure. 2. A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is
usually the result of a faulty or improperly installed
drainback valve, a damaged main cooler, or severe restrictions in the coolers and lines caused by
debris or kinked lines.
3. Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer
towing or similar high load operation will overheat
the transmission fluid if the vehicle is improperly equipped. Such vehicles should have an auxiliary
transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination
needed to handle heavy loads.

Fluid - A/T: Testing and Inspection Fluid Contamination
FLUID CONTAMINATION
Transmission fluid contamination is generally a result of:
- adding incorrect fluid
- failure to clean dipstick and fill tube when checking level
- engine coolant entering the fluid
- internal failure that generates debris
- overheat that generates sludge (fluid breakdown)
- failure to reverse flush cooler and lines after repair
- failure to replace contaminated converter after repair
The use of non-recommended fluids can result in transmission failure. The usual results are erratic
shifts, slippage, abnormal wear and eventual failure due to fluid breakdown and sludge formation.
Avoid this condition by using recommended fluids only.
The dipstick cap and fill tube should be wiped clean before checking fluid level. Dirt, grease and
other foreign material on the cap and tube could fall into the tube if not removed beforehand. Take
the time to wipe the cap and tube clean before withdrawing the dipstick.
Engine coolant in the transmission fluid is generally caused by a cooler malfunction. The only
remedy is to replace the radiator as the cooler in the radiator is not a serviceable part.
If coolant has circulated through the transmission, an overhaul is necessary.
The transmission cooler and lines should be reverse flushed whenever a malfunction generates
sludge and/or debris. The torque converter should also be replaced at the same time.
Failure to flush the cooler and lines will result in recontamination. Flushing applies to auxiliary
coolers as well. The torque converter should also be replaced whenever a failure generates sludge
and debris. This is necessary because normal converter flushing procedures will not remove all
contaminants.

Information > Service and Repair > Fluid Level Check
Fluid - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells
burned, and is contaminated with metal or friction material particles, a complete transmission
recondition is needed. Be sure to examine the fluid on the dipstick closely. If there is any doubt
about its condition, drain out a sample for a double check.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F.), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up DRB@ scan tool and select transmission. 6. Select sensors. 7.
Read the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.

Transmission Fluid Temperature Chart
INSPECTION Inspect bottom of pan and magnet for excessive amounts of metal. A light coating of
clutch material on the bottom of the pan does not indicate a problem unless accompanied by a
slipping condition or shift lag. If fluid and pan are contaminated with excessive amounts of debris.
CLEANING 1. Using a suitable solvent, clean pan and magnet. 2. Using a suitable gasket scraper,
clean original sealing material from surface of transmission case and the transmission pan.
INSTALLATION 1. Install a new oil filter seal into the bottom of the oil pump.
NOTE: Do not attempt to install the seal onto the oil filter first and then into the oil pump. An
unsatisfactory seal between the oil pump and filter will result, allowing air to be drawn into the
pump.
2. Place replacement filter in position on valve body and into the oil pump. 3. Install screw to hold
filter to valve body (Fig. 54). Tighten screw to 4.5 Nm (40 inch lbs.) torque. 4. Install new cooler
return filter onto the transmission, if necessary. Torque the filter to 14.12 Nm (125 inch lbs.). 5.
Place bead of Mopar(R) RTV sealant onto the transmission case sealing surface. 6. Place pan in
position on transmission. 7. Install bolts to hold pan to transmission. Tighten bolts to 11.8 Nm (105
inch lbs.) torque. 8. Lower vehicle and fill transmission with Mopar(R) ATF +4, type 9602 fluid.

NOTE:
This bulletin applies to vehicles equipped with a 45RFE or a 545RFE automatic transmission (sales
code DG4 or DGQ respectively).
DISCUSSION:
The customer may experience an initial delayed shift engagement following an extended off (not
running) period of time, generally after being parked overnight. The initial shift engagement may
feel like a delay or slip when a transmission gear (reverse or drive) is first selected after engine
start.
The customer may not have experienced the delayed shift engagement until after the transmission
has been serviced, where the cooler return filter was replaced during the service and/or repair.
The condition is not detrimental to the transmission but may cause concern with the customer.
The above condition may be caused by a suspect cooler return filter a part number of
04799662AB. This "AB" suffix / level filter may allow transmission fluid to drain back out of the
torque converter. The drain back condition may occur over a period time when the engine (and
transmission) are not running. With less fluid in the torque converter a delay in gear engagement
may occur at engine start up while the torque converter fills to its proper fluid level.
All 04799662AB cooler return filters with the "AB" suffix are suspect. The above condition may be
corrected by replacing a suspect "AB" filter with a new cooler return filter whose part number is
04799662 (with no suffix or with a suffix that is other than the "AB" level).
NOTE:
The cooler return filter, p/n 04799662, will not be available until September 09, 2005. The filter part
number is stenciled on the side of the filter case.

Fluid Filter - A/T: Service and Repair Fluid Level Check
FLUID LEVEL CHECK
Low fluid level can cause a variety of conditions because it allows the pump to take in air along with
the fluid. As in any hydraulic system, air bubbles make the fluid spongy, therefore, pressures will be
low and build up slowly.
Improper filling can also raise the fluid level too high. When the transmission has too much fluid,
the geartrain churns up foam and cause the same conditions which occur with a low fluid level.
In either case, air bubbles can cause overheating and/or fluid oxidation, and varnishing. This can
interfere with normal valve, clutch, and accumulator operation. Foaming can also result in fluid
escaping from the transmission vent where it may be mistaken for a leak.
Along with fluid level, it is important to check the condition of the fluid. When the fluid smells
burned, and is contaminated with metal or friction material particles, a complete transmission
recondition is needed. Be sure to examine the fluid on the dipstick closely. If there is any doubt
about its condition, drain out a sample for a double check.
After the fluid has been checked, seat the dipstick fully to seal out water and dirt.
The transmission has a dipstick to check oil level. It is located on the right side of the engine. Be
sure to wipe all dirt from dipstick handle before removing.
The torque converter fills in both the P (PARK) and N (NEUTRAL) positions. Place the selector
lever in P (PARK) to be sure that the fluid level check is accurate. The engine should be running at
idle speed for at least one minute, with the vehicle on level ground. At normal operating
temperature (approximately 82°C. or 180°F.), the fluid level is correct if it is in the HOT region
(cross-hatched area) on the oil level indicator. The fluid level will be approximately at the upper
COLD hole of the dipstick at 70°F fluid temperature.
NOTE: Engine and Transmission should be at normal operating temperature before performing this
procedure.
1. Start engine and apply parking brake. 2. Shift the transmission into DRIVE for approximately 2
seconds. 3. Shift the transmission into REVERSE for approximately 2 seconds. 4. Shift the
transmission into PARK. 5. Hook up DRB@ scan tool and select transmission. 6. Select sensors. 7.
Read the transmission temperature value. 8. Compare the fluid temperature value with the chart. 9.
Adjust transmission fluid level shown on the dipstick according to the chart.
NOTE: After adding any fluid to the transmission, wait a minimum of 2 minutes for the oil to fully
drain from the fill tube into the transmission before rechecking the fluid level.
10. Check transmission for leaks.

The oil pump (Fig. 85) is located at the front of the transmission inside the bell housing and behind
the transmission front cover. The oil pump consists of two independent pumps (Fig. 86), a number
of valves (Fig. 87), a front seal (Fig. 88), and a bolt on reaction shaft. The converter clutch switch
and regulator valves, pressure regulator valve, and converter pressure limit valve are all located in
the oil pump housing.

Component Information > Specifications > Page 3639
OPERATION
As the torque converter rotates, the converter hub rotates the oil pump drive gear. As the drive
gear rotates both driven gears, the clearance between the gear teeth increases in the crescent
area, and creates a suction at the inlet side of the pump. This suction draws fluid through the pump
inlet from the oil pan. As the clearance between the gear teeth in the crescent area decreases, it
forces pressurized fluid into the pump outlet and to the oil pump valves. At low speeds, both pumps
supply fluid to the transmission. As the speed of the torque converter increases, the pressure
output of both pumps increases until the primary pump pressure reaches the point where it can
close off the check valve located between the two pumps. When the check valve is closed, the
secondary pump is shut down and the primary pump supplies all the fluid to the transmission.
CONVERTER CLUTCH SWITCH VALVE The converter clutch switch valve is used to control the
hydraulic pressure supplied to the front (OFF) side of the torque converter clutch.
CONVERTER CLUTCH REGULATOR VALVE The converter clutch regulator valve is used to
control the hydraulic pressure supplied to the back (ON) side of the torque converter clutch.
TORQUE CONVERTER LIMIT VALVE The torque converter limit valve serves to limit the available
line pressure to the torque converter clutch to approximately 120 psi.

Fluid Pump: Testing and Inspection
STANDARD PROCEDURE - OIL PUMP VOLUME CHECK
Measuring the oil pump output volume will determine if sufficient oil flow to the transmission oil
cooler exists, and whether or not an internal transmission failure is present. Verify that the
transmission fluid is at the proper level. Refer to the Fluid Level Check procedure. If necessary, fill
the transmission to the proper level with Mopar(R) ATF +4, type 9602, Automatic Transmission
Fluid. 1. Disconnect the To cooler line at the cooler inlet and place a collecting container under the
disconnected line.
CAUTION: With the fluid set at the proper level, fluid collection should not exceed (1) quart or
internal damage to the transmission may occur.
2. Run the engine at 1800 rpm, with the shift selector in neutral. Verify that the transmission fluid
temperature is below 104.5°C (220°F) for this test. 3. If one quart of transmission fluid is collected
in the container in 30 seconds or less, oil pump flow volume is within acceptable limits. If fluid flow
is intermittent, or it takes more than 30 seconds to collect one quart of fluid, refer to the Hydraulic
Pressure tests for further diagnosis.
4. Re-connect the To cooler line to the transmission cooler inlet. 5. Refill the transmission to proper
level.

Fluid Pump: Service and Repair Cleaning and Inspection
CLEANING
Clean pump and support components with solvent and dry them with compressed air.
INSPECTION
Check condition of the seal rings and thrust washer on the reaction shaft support. The seal rings do
not need to be replaced unless cracked, broken, or severely worn. Inspect the pump and support
components. Replace the pump or support if the seal ring grooves or machined surfaces are worn,
scored, pitted, or damaged. Replace the pump gears if pitted, worn chipped, or damaged. Inspect
the pump bushing. Then check the reaction shaft support bushing. Replace either bushing only if
heavily worn, scored or damaged. It is not necessary to replace the bushings unless they are
actually damaged. Inspect the valves and plugs for scratches, burrs, nicks, or scores. Minor
surface scratches on steel valves and plugs can be removed with crocus cloth but do not round off
the edges of the valve or plug lands. Maintaining sharpness of these edges is vitally important. The
edges prevent foreign matter from lodging between the valves and plugs and the bore. Inspect all
the valve and plug bores in the oil pump cover. Use a penlight to view the bore interiors. Replace
the oil pump if any bores are distorted or scored. Inspect all of the valve springs. The springs must
be free of distortion, warpage or broken coils. Trial fit each valve and plug in its bore to check
freedom of operation. When clean and dry, the valves and plugs should drop freely into the bores.

Governor: Description and Operation
DESCRIPTION
Governor pressure is controlled electronically. Components used for governor pressure control
include: Governor body
- Valve body transfer plate
- Governor pressure solenoid valve
- Governor pressure sensor
- Fluid temperature thermistor
- Throttle position sensor (TPS)
- Transmission speed sensor
- Powertrain control module (PCM)
GOVERNOR PRESSURE SOLENOID VALVE
The solenoid valve is a duty-cycle solenoid which regulates the governor pressure needed for
upshifts and downshifts. It is an electro-hydraulic device located in the governor body on the valve
body transfer plate (Fig. 74).
GOVERNOR PRESSURE SENSOR
The governor pressure sensor measures output pressure of the governor pressure solenoid valve
(Fig. 75).
GOVERNOR BODY AND TRANSFER PLATE The transfer plate is designed to supply
transmission line pressure to the governor pressure solenoid valve and to return governor
pressure. The governor pressure solenoid valve is mounted in the governor body. The body is
bolted to the lower side of the transfer plate (Fig. 75).
GOVERNOR PRESSURE CURVES There are four governor pressure curves programmed into the
transmission control module. The different curves allow the control module to adjust governor
pressure for varying conditions. One curve is used for operation when fluid temperature is at, or
below, -1°C (30°F). A second curve is used when fluid temperature is at, or above, 10°C (50°F)
during normal city or highway driving. A third curve is used during wide-open throttle operation. The
fourth curve is used when driving with the transfer case in low range.
OPERATION
Compensation is required for performance variations of two of the input devices. Though the slope
of the transfer functions is tightly controlled, offset
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Governor, A/T >
Component Information > Locations > Page 3651
may vary due to various environmental factors or manufacturing tolerances. The pressure
transducer is affected by barometric pressure as well as temperature. Calibration of the zero
pressure offset is required to compensate for shifting output due to these factors. Normal
calibration will be performed when sump temperature is above 50 degrees F, or in the absence of
sump temperature data, after the first 10 minutes of vehicle operation. Calibration of the pressure
transducer offset occurs each time the output shaft speed falls below 200 RPM. Calibration shall be
repeated each 3 seconds the output shaft speed is below 200 RPM. A 0.5 second pulse of 95%
duty cycle is applied to the governor pressure solenoid valve and the transducer output is read
during this pulse. Averaging of the transducer signal is necessary to reject electrical noise. Under
cold conditions (below 50 degrees F sump), the governor pressure solenoid valve response may
be too slow to guarantee 0 psi during the 0.5 second calibration pulse. Calibration pulses are
continued during this period, however the transducer output valves are discarded. Transducer
offset must be read at key-on, under conditions which promote a stable reading. This value is
retained and becomes the offset during the "cold" period of operation.
GOVERNOR PRESSURE SOLENOID VALVE The inlet side of the solenoid valve is exposed to
normal transmission line pressure. The outlet side of the valve leads to the valve body governor
circuit. The solenoid valve regulates line pressure to produce governor pressure. The average
current supplied to the solenoid controls governor pressure. One amp current produces zero
kPa/psi governor pressure. Zero amps sets the maximum governor pressure. The powertrain
control module (PCM) turns on the trans control relay which supplies electrical power to the
solenoid valve. Operating voltage is 12 volts (DC). The PCM controls the ground side of the
solenoid using the governor pressure solenoid control circuit.
GOVERNOR PRESSURE SENSOR The sensor output signal provides the necessary feedback to
the PCM. This feedback is needed to adequately control governor pressure.
GOVERNOR BODY AND TRANSFER PLATE The transfer plate channels line pressure to the
solenoid valve through the governor body. It also channels governor pressure from the solenoid
valve to the governor circuit. It is the solenoid valve that develops the necessary governor
pressure.
GOVERNOR PRESSURE CURVES
LOW TRANSMISSION FLUID TEMPERATURE When the transmission fluid is cold the
conventional governor can delay shifts, resulting in higher than normal shift speeds and harsh
shifts. The electronically controlled low temperature governor pressure curve is higher than normal
to make the transmission shift at normal speeds and sooner. The PCM uses a temperature sensor
in the transmission oil sump to determine when low temperature governor pressure is needed.
NORMAL OPERATION Normal operation is refined through the increased computing power of the
PCM and through access to data on engine operating conditions provided by the PCM that were
not available with the previous stand-alone electronic module. This facilitated the development of a
load adaptive shift strategy - the ability to alter the shift schedule in response to vehicle load
condition. One manifestation of this capability is grade "hunting" prevention - the ability of the
transmission logic to delay an upshift; on a grade if the engine does not have sufficient power to
maintain speed in the higher gear. The 3-2 downshift and the potential for hunting between gears
occurs with a heavily loaded vehicle or on steep grades. When hunting occurs, it is very
objectionable because shifts are frequent and accompanied by large changes in noise and
acceleration.
WIDE OPEN THROTTLE OPERATION In wide-open throttle (WOT) mode, adaptive memory in the
PCM assures that up-shifts occur at the preprogrammed optimum speed. WOT operation is
determined from the throttle position sensor, which is also a part of the emission control system.
The initial setting for the WOT upshift is below the optimum engine speed. As WOT shifts are
repeated, the PCM learns the time required to complete the shifts by comparing the engine speed
when the shifts occur to the optimum speed. After each shift, the PCM adjusts the shift point until
the optimum speed is reached. The PCM also considers vehicle loading, grade and engine
performance changes due to high altitude in determining when to make WOT shifts. It does this by
measuring vehicle and engine acceleration and then factoring in the shift time.
TRANSFER CASE LOW RANGE OPERATION On four-wheel drive vehicles operating in low
range, the engine can accelerate to its peak more rapidly than in Normal range, resulting in
delayed shifts and undesirable engine "flare." The low range governor pressure curve is also higher
than normal to initiate upshifts sooner. The PCM compares electronic vehicle speed signal used by
the speedometer to the transmission output shaft speed signal to determine when the transfer case
is in low range.

Overdrive Indicator Lamp: Description and Operation
OVERDRIVE OFF INDICATOR
An overdrive OFF indicator is standard equipment on all instrument clusters. However, on vehicles
not equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The overdrive OFF indicator consists of the text "O/D OFF", which appears in the lower
portion of the electronic gear selector indicator Vacuum Fluorescent Display (VFD). The VFD is
part of the cluster electronic circuit board, and is visible through a cutout located in the lower right
corner of the cluster overlay. The dark lens of the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "O/D OFF" appears in an amber color and at the same
lighting level as the gear selector indicator information when it is illuminated by the instrument
cluster electronic circuit board. The overdrive OFF indicator is serviced as a unit with the VFD in
the instrument cluster.
The overdrive OFF indicator gives an indication to the vehicle operator when the OFF position of
the overdrive OFF switch has been selected, disabling the electronically controlled overdrive
feature of the automatic transmission. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The overdrive OFF indicator receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the indicator will always be OFF when the ignition switch
is in any position except ON or Start. The indicator only illuminates when it is switched to ground by
the instrument cluster circuitry. The instrument cluster will turn ON the overdrive OFF indicator for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the overdrive OFF indicator
is illuminated for about two seconds as a bulb test.
- Overdrive OFF Lamp-ON Message - Each time the cluster receives an overdrive OFF lamp-ON
message from the PCM indicating that the OFF position of the overdrive OFF switch has been
selected, the overdrive OFF indicator will be illuminated. The indicator remains illuminated until the
cluster receives an overdrive OFF lamp-OFF message from the PCM, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the overdrive OFF indicator
will be turned ON, then OFF again during the VFD portion of the test to confirm the functionality of
the VFD, and again during the bulb check portion of the test to confirm the functionality of the
cluster control circuitry.
The PCM continually monitors the overdrive OFF switch to determine the proper outputs to the
automatic transmission. The PCM then sends the proper overdrive OFF lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the overdrive OFF indicator or the
instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT/CLUSTER DIAGNOSIS AND TESTING). For proper diagnosis of the overdrive control system, the PCM, the
PCI data bus, or the message inputs to the instrument cluster that control the overdrive OFF
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator lamp is standard equipment on all instrument clusters.
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

> Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram Information and
Instructions > Page 3716
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Transmission Control Module: Description and Operation
Fig. 13 Transmission Control Module Location
The Transmission Control Module (TCM) is located in the engine compartment on the right
(passenger) side and is mounted to the radiator core support (Fig. 13).
The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Relays and Modules - A/T
> Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 3737
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Relays and Modules - A/T
> Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 3738
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

> Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page 3739
Driving Conditions
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the
following chart to determine the appropriate operation expected, depending on driving conditions.

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

Temperature Warning Indicator - A/T: Locations
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center.

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Temperature Warning
Indicator - A/T > Component Information > Locations > Page 3842
Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator lamp is standard equipment on all instrument clusters.
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

Throttle Valve Cable/Linkage: Adjustments 42RE (A-500) 4 Speed
ADJUSTMENTS - TRANSMISSION THROTTLE VALVE CABLE
A correctly adjusted throttle valve cable will cause the throttle lever on the transmission to move
simultaneously with the throttle body lever from the idle position. Proper adjustment will allow
simultaneous movement without causing the transmission throttle lever to either move ahead of, or
lag behind the lever on the throttle body.
ADJUSTMENT VERIFICATION
1. Turn ignition key to OFF position. 2. Remove air cleaner.

3. Verify that lever on throttle body is at curb idle position (Fig. 239). Then verify that the
transmission throttle lever (Fig. 240) is also at idle (fully
forward) position.
4. Slide cable off attachment stud on throttle body lever. 5. Compare position of cable end to
attachment stud on throttle body lever:
- Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm
(0.039 inch) in either direction (Fig. 241).

- If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as
described in Throttle Valve Cable Adjustment procedure.
6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of
transmission throttle lever and lever on throttle body.
- If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is
correct.
- If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment
will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed
position, cable adjustment will be necessary.
ADJUSTMENT PROCEDURE
1. Turn ignition switch to OFF position. 2. Remove air cleaner if necessary. 3. Disconnect cable
end from attachment stud. Carefully slide cable off stud. Do not pry or pull cable off. 4. Verify that
transmission throttle lever is in fully closed position. Then be sure lever on throttle body is at curb
idle position. 5. Pry the T.V, cable lock (A) into the UP position (Fig. 241). This will unlock the cable
and allow for readjustment. 6. Apply just enough tension on the T.V. cable (B) to remove any slack
in the cable. Pulling too tight will cause the T.V. lever on the transmission to
move out of its idle position, which will result in an incorrect T.V. cable adjustment. Slide the sheath
of the T.V. cable (D) back and forth until the centerlines of the T.V. cable end (B) and the throttle
bell crank lever (C) are aligned within one millimeter (1mm) (Fig. 241).
7. While holding the T.V. cable in the set position push the TX cable lock (A) into the down position
(Fig. 241). This will lock the present T.V cable
adjustment.
NOTE: Be sure that as the cable is pulled forward and centered on the throttle lever stud, the cable
housing moves smoothly with the cable. Due to the angle at which the cable housing enters the
spring housing, the cable housing may bind slightly and create an incorrect adjustment.
8. Reconnect the T.V. cable (B) to the throttle bellcrank lever (C). 9. Check cable adjustment. Verify
transmission throttle lever and lever on throttle body move simultaneously.

Torque Converter: Description and Operation 42RE (A-500) 4 Speed
DESCRIPTION
The torque converter (Fig. 242) is a hydraulic device that couples the engine crankshaft to the
transmission. The torque converter consists of an outer shell with an internal turbine, a stator, an
overrunning clutch, an impeller and an electronically applied converter clutch. The converter clutch
provides reduced engine speed and greater fuel economy when engaged. Clutch engagement also
provides reduced transmission fluid temperatures. The torque converter hub drives the
transmission oil (fluid) pump. The torque converter is a sealed, welded unit that is not repairable
and is serviced as an assembly.
CAUTION: The torque converter must be replaced if a transmission failure resulted in large
amounts of metal or fiber contamination in the fluid. If the fluid is contaminated, flush the all
transmission fluid cooler(s) and lines.

The impeller (Fig. 243) is an integral part of the converter housing. The impeller consists of curved
blades placed radially along the inside of the housing on the transmission side of the converter. As
the converter housing is rotated by the engine, so is the impeller, because they are one and the
same and are the driving members of the system.

The turbine (Fig. 244) is the output, or driven, member of the converter. The turbine is mounted
within the housing opposite the impeller, but is not attached to the housing. The input shaft is
inserted through the center of the impeller and splined into the turbine. The design of the turbine is
similar to the impeller, except the blades of the turbine are curved in the opposite direction.

The stator assembly (Fig. 245) is mounted on a stationary shaft which is an integral part of the oil
pump. The stator is located between the impeller and turbine within the torque converter case (Fig.
246). The stator contains an over-running clutch, which allows the stator to rotate only in a
clockwise direction. When the stator is locked against the over-running clutch, the torque
multiplication feature of the torque converter is operational.
TORQUE CONVERTER CLUTCH (TCC)
The TCC (Fig. 247) was installed to improve the efficiency of the torque converter that is lost to the
slippage of the fluid coupling. Although the fluid coupling provides smooth, shock-free power
transfer, it is natural for all fluid couplings to slip. If the impeller and turbine were mechanically
locked together, a zero slippage condition could be obtained. A hydraulic piston was added to the
turbine, and a friction material was added to the inside of the front cover to provide this mechanical
lock-up.

The converter impeller (Fig. 248) (driving member), which is integral to the converter housing and
bolted to the engine drive plate, rotates at engine speed. The converter turbine (driven member),
which reacts from fluid pressure generated by the impeller, rotates and turns the transmission input
shaft.
TURBINE As the fluid that was put into motion by the impeller blades strikes the blades of the
turbine, some of the energy and rotational force is transferred into the turbine and the input shaft.
This causes both of them (turbine and input shaft) to rotate in a clockwise direction following the
impeller. As the fluid is leaving the trailing edges of the turbine's blades it continues in a "hindering"
direction back toward the impeller. If the fluid is not redirected before it strikes the impeller, it will
strike the impeller in such a direction that it would tend to slow it down.
STATOR
Torque multiplication is achieved by locking the stator's over-running clutch to its shaft (Fig. 249).
Under stall conditions (the turbine is stationary), the oil leaving the turbine blades strikes the face of
the stator blades and tries to rotate them in a counterclockwise direction. When this happens the
overrunning clutch of the stator locks and holds the stator from rotating. With the stator locked, the
oil strikes the stator blades and is redirected into a

"helping" direction before it enters the impeller. This circulation of oil from impeller to turbine,
turbine to stator, and stator to impeller, can produce a maximum torque multiplication of about
2.4:1. As the turbine begins to match the speed of the impeller, the fluid that was hitting the stator
in such as way as to cause it to lock-up is no longer doing so. In this condition of operation, the
stator begins to free wheel and the converter acts as a fluid coupling.
TORQUE CONVERTER CLUTCH (TCC) The torque converter clutch is hydraulically applied and is
released when fluid is vented from the hydraulic circuit by the torque converter control (TCC)
solenoid on the valve body. The torque converter clutch is controlled by the Powertrain Control
Module (PCM). The torque converter clutch engages in fourth gear, and in third gear under various
conditions, such as when the O/D switch is OFF, when the vehicle is cruising on a level surface
after the vehicle has warmed up. The torque converter clutch will disengage momentarily when an
increase in engine load is sensed by the PCM, such as when the vehicle begins to go uphill or the
throttle pressure is increased.

The stator assembly (Fig. 109) is mounted on a stationary shaft which is an integral part of the oil
pump. The stator is located between the impeller and turbine within the torque converter case (Fig.

locked together, a zero slippage condition could be obtained. A hydraulic piston with friction
material was added to the turbine assembly to provide this mechanical lock-up. In order to reduce
heat build-up in the transmission and buffer the powertrain against torsional vibrations, the TCM
can duty cycle the L/R-CC Solenoid to achieve a smooth application of the torque converter clutch.
This function, referred to as Electronically Modulated Converter Clutch (EMCC) can occur at
various times depending on the following variables:

Torque multiplication is achieved by locking the stator's over-running clutch to its shaft (Fig. 113).
Under stall conditions (the turbine is stationary), the oil leaving the turbine blades strikes the face of
the stator blades and tries to rotate them in a counterclockwise direction. When this happens the
over-running clutch of the stator locks and holds the stator from rotating. With the stator locked, the
oil strikes the stator blades and is redirected into a "helping" direction before it enters the impeller.
This circulation of oil from impeller to turbine, turbine to stator, and stator to impeller, can produce a
maximum torque multiplication of about 2.4:1. As the turbine begins to match the speed of the
impeller, the fluid that was hitting the stator in such as way as to cause it to lock-up is no longer
doing so. In this condition of operation, the stator begins to free wheel and the converter acts as a
fluid coupling.
TORQUE CONVERTER CLUTCH (TCC) In a standard torque converter, the impeller and turbine
are rotating at about the same speed and the stator is freewheeling, providing no torque
multiplication. By applying the turbine's piston and friction material to the front cover, a total
converter engagement can be obtained. The result of this engagement is a direct 1:1 mechanical
link between the engine and the transmission. The clutch can be engaged in second, third, and
fourth gear ranges depending on overdrive control switch position. If the overdrive control switch is
in the normal ON position, the clutch will engage after the shift to fourth gear, and above
approximately 72 km/h (45 mph). If the control switch is in the OFF position, the clutch will engage
after the shift to third gear, at approximately 56 km/h (35 mph) at light throttle. The TCM controls
the torque converter by way of internal logic software. The programming of the software provides
the TCM with control over the L/R-CC Solenoid. There are four output logic states that can be
applied as follows: No EMCC
- Partial EMCC
- Full EMCC
- Gradual-to-no EMCC
NO EMCC Under No EMCC conditions, the L/R Solenoid is OFF. There are several conditions that
can result in NO EMCC operations. No EMCC can be initiated due to a fault in the transmission or
because the TCM does not see the need for EMCC under current driving conditions.
PARTIAL EMCC Partial EMCC operation modulates the L/R Solenoid (duty cycle) to obtain partial
torque converter clutch application. Partial EMCC operation is maintained until Full EMCC is called
for and actuated. During Partial EMCC some slip does occur. Partial EMCC will usually occur at
low speeds, low load and light throttle situations.
FULL EMCC During Full EMCC operation, the TCM increases the L/R Solenoid duty cycle to full
ON after Partial EMCC control brings the engine speed within the desired slip range of
transmission input speed relative to engine rpm.
GRADUAL-TO-NO EMCC This operation is to soften the change from Full or Partial EMCC to No
EMCC. This is done at mid throttle by decreasing the L/R Solenoid duty cycle.

This causes both of them (turbine and input shaft) to rotate in a clockwise direction following the
impeller. As the fluid is leaving the trailing edges of the turbine's blades it continues in a "hindering"
direction back toward the impeller. If the fluid is not redirected before it strikes the impeller, it will
strike the impeller in such a direction that it would tend to slow it down.
STATOR
Torque multiplication is achieved by locking the stator's over-running clutch to its shaft (Fig. 250).
Under stall conditions (the turbine is stationary), the oil leaving the turbine blades strikes the face of
the stator blades and tries to rotate them in a counterclockwise direction. When this happens the
overrunning clutch of the stator locks and holds the stator from rotating. With the stator locked, the
oil strikes the stator blades and is redirected into a "helping" direction before it enters the impeller.
This circulation of oil from impeller to turbine, turbine to stator, and stator to impeller, can produce a

maximum torque multiplication of about 2.4:1. As the turbine begins to match the speed of the
impeller, the fluid that was hitting the stator in such as way as to cause it to lock-up is no longer
doing so. In this condition of operation, the stator begins to free wheel and the converter acts as a
fluid coupling.
TORQUE CONVERTER CLUTCH (TCC) The torque converter clutch is hydraulically applied and is
released when fluid is vented from the hydraulic circuit by the torque converter control (TCC)
solenoid on the valve body. The torque converter clutch is controlled by the Powertrain Control
Module (PCM). The torque converter clutch engages in fourth gear, and in third gear under various
conditions, such as when the O/D switch is OFF, when the vehicle is cruising on a level surface
after the vehicle has warmed up. The torque converter clutch will disengage momentarily when an
increase in engine load is sensed by the PCM, such as when the vehicle begins to go uphill or the
throttle pressure is increased.

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Transmission Cooler: Service and Repair
FLUSHING COOLERS AND TUBES
When a transmission failure has contaminated the fluid, the oil cooler(s) must be flushed. The
torque converter must also be replaced. This will insure that metal particles or sludged oil are not
later transferred back into the reconditioned (or replaced) transmission. The only recommended
procedure for flushing coolers and lines is to use Tool 6906-B Cooler Flusher.
WARNING: WEAR PROTECTIVE EYE WEAR THAT MEETS THE REQUIREMENTS OF OSHA
AND ANSI Z87.1-1968. WEAR STANDARD INDUSTRIAL RUBBER GLOVES. KEEP LIGHTED
CIGARETTES, SPARKS, FLAMES, AND OTHER IGNITION SOURCES AWAY FROM THE AREA
TO PREVENT THE IGNITION OF COMBUSTIBLE LIQUIDS AND GASES. KEEP A CLASS (B)
FIRE EXTINGUISHER IN THE AREA WHERE THE FLUSHER WILL BE USED. KEEP THE AREA
WELL VENTILATED. DO NOT LET FLUSHING SOLVENT COME IN CONTACT WITH YOUR
EYES OR SKIN: IF EYE CONTAMINATION OCCURS, FLUSH EYES WITH WATER FOR 15 TO
20 SECONDS. REMOVE CONTAMINATED CLOTHING AND WASH AFFECTED SKIN WITH
SOAP AND WATER. SEEK MEDICAL ATTENTION.
1. Remove cover plate filler plug on Tool 6906-B. Fill reservoir 1/2 to 3/4 full of fresh flushing
solution. Flushing solvents are petroleum based
solutions generally used to clean automatic transmission components. DO NOT use solvents
containing acids, water, gasoline, or any other corrosive liquids.
2. Reinstall filler plug on Tool 6906-B. 3. Verify pump power switch is turned OFF. Connect red
alligator clip to positive (+) battery post. Connect black W alligator clip to a good ground. 4.
Disconnect the cooler lines at the transmission.
NOTE: When flushing transmission cooler and lines, ALWAYS reverse flush.
NOTE: The converter drainback valve must be removed and an appropriate replacement hose
installed to bridge the space between the transmission cooler line and the cooler fitting. Failure to
remove the drainback valve will prevent reverse flushing the system. A suitable replacement hose
can be found in the adapter kit supplied with the flushing tool.
5. Connect the BLUE pressure line to the OUTLET (From) cooler line. 6. Connect the CLEAR
return line to the INLET (To) cooler line 7. Turn pump ON for two to three minutes to flush cooler(s)
and lines. 8. Turn pump OFF. 9. Disconnect CLEAR suction line from reservoir at cover plate.
Disconnect CLEAR return line at cover plate, and place it in a drain pan.
10. Turn pump ON for 30 seconds to purge flushing solution from cooler and lines. Turn pump
OFF. 11. Place CLEAR suction line into a one quart container of Mopar ATF +4, type 9602,
Automatic Transmission Fluid. 12. Turn pump ON until all transmission fluid is removed from the
one quart container and lines. This purges any residual cleaning solvent from the
transmission cooler and lines. Turn pump OFF.
13. Disconnect alligator clips from battery. Reconnect flusher lines to cover plate, and remove
flushing adapters from cooler lines.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following: Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

Transmission Solenoid/TRS Assembly
TRANSMISSION SOLENOID/TRS ASSEMBLY DESCRIPTION
The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve
body assembly (Fig. 115). The assembly consists of six solenoids that control hydraulic pressure to
the six friction elements (transmission clutches), and the torque converter clutch. The pressure
control solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly
also contains five pressure switches that feed information to the TCM.
OPERATION SOLENOIDS
Solenoids are used to control the L/R, 2C, 4C, OD, and UD friction elements. The reverse clutch is
controlled by line pressure and the position of the manual valve in the valve body. All the solenoids
are contained within the Solenoid and Pressure Switch Assembly. The solenoid and pressure
switch assembly contains one additional solenoid, Multi-Select (MS), which serves primarily to
provide 2nd and 3rd gear limp-in operation.
The solenoids receive electrical power from the Transmission Control Relay through a single wire.
The TCM energizes or operates the solenoids individually by grounding the return wire of the
solenoid as necessary. When a solenoid is energized, the solenoid valve shifts, and a fluid
passage is opened or closed (vented or applied), depending on its default operating state. The
result is an apply or release of a frictional element.
The MS and UD solenoids are normally applied to allow transmission limp-in in the event of an
electrical failure.
The continuity of the solenoids and circuits are periodically tested. Each solenoid is turned on or off
depending on its current state. An inductive spike should be detected by the TCM during this test. If
no spike is detected, the circuit is tested again to verify the failure. In addition to the periodic
testing, the solenoid circuits are tested if a speed ratio or pressure switch error occurs.
PRESSURE SWITCHES

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T >
Component Information > Description and Operation > Solenoid Body > Page 3975
The TCM relies on five pressure switches to monitor fluid pressure in the L/R, 2C, 4C, LTD, and
OD hydraulic circuits. The primary purpose of these switches is to help the TCM detect when clutch
circuit hydraulic failures occur. The switches close at 23 psi and open at 11 psi, and simply indicate
whether or not pressure exists. The switches are continuously monitored by the TCM for the
correct states (open or closed) in each gear as shown in the following chart: L/R is closed if output speed is below 100 rpm in Drive and Manual 2. L/R is open in Manual 1. A
Diagnostic Trouble Code (DTC) will set if the TCM senses any switch open or closed at the wrong
time in a given gear.
Solenoid Switch Valve
SOLENOID SWITCH VALVE
DESCRIPTION The Solenoid Switch Valve (SSV) is located in the valve body and controls the
direction of the transmission fluid when the L/R-TCC solenoid is energized.
OPERATION The Solenoid Switch Valve controls line pressure from the LR-TCC solenoid. In 1st
gear, the SSV will be in the downshifted position, thus directing fluid to the L/R clutch circuit. In
2nd, 3rd, and 4th, the solenoid switch valve will be in the upshifted position and directs the fluid into
the torque converter clutch (TCC) circuit.
When shifting into 1st gear, a special hydraulic sequence is performed to ensure SSV movement
into the downshifted position. The L/R pressure switch is monitored to confirm SSV movement. If
the movement is not confirmed (the L/R pressure switch does not close), 2nd gear is substituted for
1st. A DTC will be set after three unsuccessful attempts are made to get into 1st gear in one given
key start.
Solenoids
SOLENOIDS
DESCRIPTION The typical electrical solenoid used in automotive applications is a linear actuator.
It is a device that produces motion in a straight line. This straight line motion can be either forward
or backward in direction, and short or long distance.
A solenoid is an electromechanical device that uses a magnetic force to perform work. It consists of
a coil of wire, wrapped around a magnetic core made from steel or iron, and a spring loaded,
movable plunger, which performs the work, or straight line motion.
The solenoids used in transmission applications are attached to valves which can be classified as
normally open or normally closed. The normally open solenoid valve is defined as a valve which
allows hydraulic flow when no current or voltage is applied to the solenoid. The normally closed
solenoid valve is defined as a valve which does not allow hydraulic flow when no current or voltage
is applied to the solenoid. These valves perform hydraulic control functions for the transmission
and must therefore be durable and tolerant of dirt particles. For these reasons, the valves have
hardened steel poppets and ball valves. The solenoids operate the valves directly, which means
that the solenoids must have very high outputs to close the valves against the sizable flow areas
and line pressures found in current transmissions. Fast response time is also necessary to ensure
accurate control of the transmission.
The strength of the magnetic field is the primary force that determines the speed of operation in a
particular solenoid design. A stronger magnetic field will cause the plunger to move at a greater
speed than a weaker one. There are basically two ways to increase the force of the magnetic field:
Increase the amount of current applied to the coil or
- Increase the number of turns of wire in the coil.
The most common practice is to increase the number of turns by using thin wire that can
completely fill the available space within the solenoid housing. The strength of the spring and the
length of the plunger also contribute to the response speed possible by a particular solenoid
design.
A solenoid can also be described by the method by which it is controlled. Some of the possibilities
include variable force, pulse-width modulated, constant ON, or duty cycle. The variable force and
pulsewidth modulated versions utilize similar methods to control the current flow through the
solenoid to position the solenoid plunger at a desired position somewhere between full ON and full
OFF. The constant ON and duty cycled versions control the voltage across the solenoid to allow
either full flow or no flow through the solenoid's valve.
OPERATION

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T >
Component Information > Description and Operation > Solenoid Body > Page 3976
When an electrical current is applied to the solenoid coil, a magnetic field is created which
produces an attraction to the plunger, causing the plunger to move and work against the spring
pressure and the load applied by the fluid the valve is controlling. The plunger is normally directly
attached to the valve which it is to operate. When the current is removed from the coil, the
attraction is removed and the plunger will return to its original position due to spring pressure.
The plunger is made of a conductive material and accomplishes this movement by providing a path
for the magnetic field to flow. By keeping the air gap between the plunger and the coil to the
minimum necessary to allow free movement of the plunger, the magnetic field is maximized.

NOTE: Refer to the Hydraulic Schematics for a visual aid in determining valve location, operation
and design.
SOLENOID SWITCH VALVE The Solenoid Switch Valve (SSV) controls the direction of the
transmission fluid when the L/R-TCC solenoid is energized. The Solenoid Switch Valve controls
line pressure from the LR-TCC solenoid. In 1st gear, the SSV will be in the downshifted position,
thus directing fluid to the 1JR clutch circuit. In 2nd, 3rd, and 4th gears, the solenoid switch valve
will be in the upshifted position and directs the fluid into the torque converter clutch (TCC) circuit.
When shifting into 1st gear, a special hydraulic sequence is performed to ensure SSV movement
into the downshifted position. The L/R pressure switch is monitored to confirm SSV movement. If
the movement is not confirmed (the L/R pressure switch does not close), 2nd gear is substituted for
1st. A DTC will be set after three unsuccessful attempts are made to get into 1st gear in one given
key start.
MANUAL VALVE
The manual valve is a relay valve. The purpose of the manual valve is to direct fluid to the correct
circuit needed for a specific gear or driving range. The manual valve, as the name implies, is
manually operated by the driver with a lever located on the top of the valve body. The valve is
connected mechanically by a cable to the gearshift mechanism. The valve is held in each of its
positions by a roller detent spring (Fig. 120) that engages the "roostercomb" of the TRS selector
plate.
LOW/REVERSE SWITCH VALVE The low/reverse switch valve allows the low/reverse clutch to be
operated by either the LR/CC solenoid or the MS solenoid.

Valve Body: Service and Repair Cleaning and Inspection
CLEANING
Clean the valve housings, valves, plugs, springs, and separator plates with a standard parts
cleaning solution only. Do not use gasoline, kerosene, or any type of caustic solution. (Fig. 128) Do
not immerse any of the electrical components in cleaning solution. Clean the electrical components
by wiping them off with dry shop towels only. Dry all except the electrical parts with compressed air.
Make sure all passages are clean and free from obstructions. Do not use rags or shop towels to dry
or wipe off valve body components. Lint from these materials can stick to valve body parts,
interfere with valve operation, and clog filters and fluid passages.
INSPECTION
Inspect all of the valve body mating surfaces for scratches, nicks, burrs, or distortion. Use a
straightedge to check surface flatness. Minor scratches may be removed with crocus cloth using
only very light pressure. Minor distortion of a valve body mating surface may be corrected by
smoothing the surface with a sheet of crocus cloth. Position the crocus cloth on a surface plate,
sheet of plate glass or equally flat surface. If distortion is severe or any surfaces are heavily scored,
the valve body will have to be replaced.

Dodge Workshop Manuals > Transmission and Drivetrain > Automatic Transmission/Transaxle > Valve Body, A/T >
Component Information > Service and Repair > Removal and Installation > Page 3986
Inspect the valves and plugs (Fig. 129) for scratches, burrs, nicks, or scores. Minor surface
scratches on steel valves and plugs can be removed with crocus cloth but do not round off the
edges of the valve or plug lands. Maintaining sharpness of these edges is vitally important. The
edges prevent foreign matter from lodging between the valves and plugs and the bore. Inspect all
the valve and plug bores in the valve body. Use a penlight to view the bore interiors. Replace the
valve body if any bores are distorted or scored. Inspect all of the valve body springs. The springs
must be free of distortion, warpage or broken coils. Trial fit each valve and plug in its bore to check
freedom of operation. When clean and dry, the valves and plugs should drop freely into the bores.
Valve body bores do not change dimensionally with use. If the valve body functioned correctly
when new, it will continue to operate properly after cleaning and inspection. It should not be
necessary to replace a valve body assembly unless it is damaged in handling. Inspect all the
accumulator bores in the valve body. Use a penlight to view the bore interiors. Replace the valve
body if any bores are distorted or scored. Inspect all of the accumulator springs. The springs must
be free of distortion, warpage or broken coils.

Inspect all the fluid seals on the valve body (Fig. 130). Replace any seals that are cracked,
distorted, or damaged in any way. These seals pass fluid pressure directly to the clutches. Any
pressure leak at these points, may cause transmission performance problems.

Drive/Propeller Shaft: Description and Operation
DESCRIPTION
A propeller shaft (Fig. 1) is the shaft which connects the transfer case to the front axle. This is the
link through which the engine power is transmitted to the axle. The propeller shaft is designed and
built with the yoke lugs in line with each other which is called zero phasing. This design produces
the smoothest running condition, an out-of-phase shaft can cause a vibration. Tubular propeller
shafts are balanced by the manufacturer with weights spot welded to the tube. Use the exact
replacement parts when installing the propeller shafts. The use of the correct replacement parts
helps to ensure safe operation. All fasteners must be torqued to the specified values for safe
operation.

Dodge Workshop Manuals > Transmission and Drivetrain > Drive/Propeller Shafts, Bearings and Joints > Drive/Propeller
Shaft > Component Information > Description and Operation > Page 4087
Also make alignment reference marks (Fig. 3) on the propeller shaft yoke and axle, or
transmission, yoke prior to servicing. This helps to eliminate possible vibration.
CAUTION: Do not allow the propeller shaft to drop or hang from any propeller shaft joint during
removal. Attach the propeller shaft to the vehicle underside with wire to prevent damage to the
joints.
OPERATION
The propeller shaft must operate through constantly changing relative angles between the
transmission and axle. It must also be capable of changing length while transmitting torque. The
axle rides suspended by springs in a floating motion. The propeller shaft must be able to change
operating angles when going over various road surfaces. This is accomplished through universal
joints/constant velocity joint, which permit the propeller shaft to operate at different angles. The slip
joints (or yokes) permit contraction or expansion. Before undercoating a vehicle, the propeller shaft
and the U-joints should be covered to prevent an out-of-balance condition and driveline vibration.
CAUTION: Use original equipment replacement parts for attaching the propeller shafts. The
specified torque must always be applied when tightening the fasteners.

Drive/Propeller Shaft: Testing and Inspection
VIBRATION
Tires that are out-of-round, or wheels that are unbalanced, will cause a low frequency vibration.
Brake drums that are unbalanced will cause a harsh, low frequency vibration.
Driveline vibration can also result from loose or damaged engine mounts.
Propeller shaft vibration increases as the vehicle speed is increased. A vibration that occurs within
a specific speed range is not usually caused by a propeller shaft being unbalanced. Defective
universal joints, or an incorrect propeller shaft angle, are usually the cause of such a vibration.
DRIVELINE VIBRATION
BALANCE
NOTE: Removing and re-indexing the propeller shaft 1800 relative to the yoke may eliminate some
vibrations.
If propeller shaft is suspected of being unbalanced, it can be verified with the following procedure:
1. Raise the vehicle. 2. Clean all the foreign material from the propeller shaft and the universal
joints. 3. Inspect the propeller shaft for missing balance weights, broken welds, and bent areas. If
the propeller shaft is bent, it must be replaced. 4. Inspect the universal joints to ensure that they
are not worn, are properly installed, and are correctly aligned with the shaft. 5. Check the universal
joint clamp screws torque. 6. Remove the wheels and tires. Install the wheel lug nuts to retain the
brake drums or rotors. 7. Mark and number the shaft six inches from the yoke end at four positions
90° apart. 8. Run and accelerate the vehicle until vibration occurs. Note the intensity and speed the
vibration occurred. Stop the engine.

9. Install a screw clamp at position 1 (Fig. 4).
10. Start the engine and re-check for vibration. If there is little or no change in vibration, move the
clamp to one of the other three positions. Repeat
the vibration test.
11. If there is no difference in vibration at the other positions, the source of the vibration may not be
propeller shaft.
12. If the vibration decreased, install a second clamp (Fig. 5) and repeat the test.
13. If the additional clamp causes an additional vibration, separate the clamps (1/2 inch above and
below the mark). Repeat the vibration test (Fig. 6). 14. Increase distance between the clamp
screws and repeat the test until the amount of vibration is at the lowest level. Bend the slack end of
the clamps
so the screws will not loosen.

Shaft > Component Information > Description and Operation > Page 4090
15. If the vibration remains unacceptable, apply the same steps to the front end of the propeller
shaft. 16. Install the wheel and tires. Lower the vehicle.
RUNOUT
1. Remove dirt, rust, paint and undercoating from the propeller shaft surface where the dial
indicator will contact the shaft. 2. The dial indicator must be installed perpendicular to the shaft
surface. 3. Measure runout at the center and ends of the shaft sufficiently far away from weld areas
to ensure that the effects of the weld process will not enter
into the measurements.
4. Refer to Runout Specifications chart. 5. If the propeller shaft runout is out of specification,
remove the propeller shaft, index the shaft 180°, and re-install the propeller shaft. Measure
shaft runout again.
6. If the propeller shaft runout is now within specifications, mark the shaft and yokes for proper
orientation. 7. If the propeller shaft runout is not within specifications, verify that the runout of the
transmission/ transfer case and axle are within specifications.
Correct as necessary and re-measure propeller shaft runout.
8. Replace the propeller shaft if the runout still exceeds the limits.

The Overdrive OFF Indicator (VFD) is part of the cluster electronic circuit board, and is visible
through a cutout located in the lower right corner of the cluster overlay.

Overdrive Indicator Lamp: Description and Operation
OVERDRIVE OFF INDICATOR
An overdrive OFF indicator is standard equipment on all instrument clusters. However, on vehicles
not equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The overdrive OFF indicator consists of the text "O/D OFF", which appears in the lower
portion of the electronic gear selector indicator Vacuum Fluorescent Display (VFD). The VFD is
part of the cluster electronic circuit board, and is visible through a cutout located in the lower right
corner of the cluster overlay. The dark lens of the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "O/D OFF" appears in an amber color and at the same
lighting level as the gear selector indicator information when it is illuminated by the instrument
cluster electronic circuit board. The overdrive OFF indicator is serviced as a unit with the VFD in
the instrument cluster.
The overdrive OFF indicator gives an indication to the vehicle operator when the OFF position of
the overdrive OFF switch has been selected, disabling the electronically controlled overdrive
feature of the automatic transmission. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The overdrive OFF indicator receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the indicator will always be OFF when the ignition switch
is in any position except ON or Start. The indicator only illuminates when it is switched to ground by
the instrument cluster circuitry. The instrument cluster will turn ON the overdrive OFF indicator for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the overdrive OFF indicator
is illuminated for about two seconds as a bulb test.
- Overdrive OFF Lamp-ON Message - Each time the cluster receives an overdrive OFF lamp-ON
message from the PCM indicating that the OFF position of the overdrive OFF switch has been
selected, the overdrive OFF indicator will be illuminated. The indicator remains illuminated until the
cluster receives an overdrive OFF lamp-OFF message from the PCM, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the overdrive OFF indicator
will be turned ON, then OFF again during the VFD portion of the test to confirm the functionality of
the VFD, and again during the bulb check portion of the test to confirm the functionality of the
cluster control circuitry.
The PCM continually monitors the overdrive OFF switch to determine the proper outputs to the
automatic transmission. The PCM then sends the proper overdrive OFF lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the overdrive OFF indicator or the
instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT/CLUSTER DIAGNOSIS AND TESTING). For proper diagnosis of the overdrive control system, the PCM, the
PCI data bus, or the message inputs to the instrument cluster that control the overdrive OFF
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator lamp is standard equipment on all instrument clusters.
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 4172
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 4173
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 4174
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.

Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Diagram
Information and Instructions > Page 4175
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
- SET THE PARKING BRAKE WHEN WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL TRANSMISSION SHOULD BE IN
NEUTRAL.
- OPERATE THE ENGINE ONLY IN A WELL-VENTILATED AREA.
- KEEP AWAY FROM MOVING PARTS WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
- TO PREVENT SERIOUS BURNS, AVOID CONTACT WITH HOT PARTS SUCH AS THE
RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
- DO NOT ALLOW FLAME OR SPARKS NEAR THE BATTERY. GASES ARE ALWAYS
PRESENT IN AND AROUND THE BATTERY.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Transmission Control Module: Description and Operation
Fig. 13 Transmission Control Module Location
The Transmission Control Module (TCM) is located in the engine compartment on the right
(passenger) side and is mounted to the radiator core support (Fig. 13).
The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Transmission and Drivetrain > Relays and Modules - Transmission and Drivetrain > Relays and
Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page
4194
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Modules - A/T > Transmission Control Module <--> [Control Module, A/T] > Component Information > Diagrams > Page
4195
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Driving Conditions
As driving conditions change, the TCM appropriately adjusts the shift schedule. Refer to the
following chart to determine the appropriate operation expected, depending on driving conditions.

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

Overdrive Indicator Lamp: Description and Operation
OVERDRIVE OFF INDICATOR
An overdrive OFF indicator is standard equipment on all instrument clusters. However, on vehicles
not equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The overdrive OFF indicator consists of the text "O/D OFF", which appears in the lower
portion of the electronic gear selector indicator Vacuum Fluorescent Display (VFD). The VFD is
part of the cluster electronic circuit board, and is visible through a cutout located in the lower right
corner of the cluster overlay. The dark lens of the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "O/D OFF" appears in an amber color and at the same
lighting level as the gear selector indicator information when it is illuminated by the instrument
cluster electronic circuit board. The overdrive OFF indicator is serviced as a unit with the VFD in
the instrument cluster.
The overdrive OFF indicator gives an indication to the vehicle operator when the OFF position of
the overdrive OFF switch has been selected, disabling the electronically controlled overdrive
feature of the automatic transmission. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The overdrive OFF indicator receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the indicator will always be OFF when the ignition switch
is in any position except ON or Start. The indicator only illuminates when it is switched to ground by
the instrument cluster circuitry. The instrument cluster will turn ON the overdrive OFF indicator for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the overdrive OFF indicator
is illuminated for about two seconds as a bulb test.
- Overdrive OFF Lamp-ON Message - Each time the cluster receives an overdrive OFF lamp-ON
message from the PCM indicating that the OFF position of the overdrive OFF switch has been
selected, the overdrive OFF indicator will be illuminated. The indicator remains illuminated until the
cluster receives an overdrive OFF lamp-OFF message from the PCM, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the overdrive OFF indicator
will be turned ON, then OFF again during the VFD portion of the test to confirm the functionality of
the VFD, and again during the bulb check portion of the test to confirm the functionality of the
cluster control circuitry.
The PCM continually monitors the overdrive OFF switch to determine the proper outputs to the
automatic transmission. The PCM then sends the proper overdrive OFF lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the overdrive OFF indicator or the
instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT/CLUSTER DIAGNOSIS AND TESTING). For proper diagnosis of the overdrive control system, the PCM, the
PCI data bus, or the message inputs to the instrument cluster that control the overdrive OFF
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

The Transmission Control Module (TCM) is the controlling unit for all electronic operations of the
transmission. The TCM receives information regarding vehicle operation from both direct and
indirect inputs, and selects the operational mode of the transmission. Direct inputs are hardwired
to, and used specifically by the TCM. Indirect inputs originate from other components/modules, and
are shared with the TCM via the vehicle communication bus.
Some examples of direct inputs to the TCM are:
- Battery (B+) voltage
- Ignition "ON" voltage
- Transmission Control Relay (Switched B+)
- Throttle Position Sensor
- Crankshaft Position Sensor
- Transmission Range Sensor
- Pressure Switches
- Transmission Temperature Sensor
- Input Shaft Speed Sensor
- Output Shaft Speed Sensor
- Line Pressure Sensor
Some examples of indirect inputs to the TCM are:
- Engine/Body Identification
- Manifold Pressure
- Target Idle
- Torque Reduction Confirmation
- Engine Coolant Temperature
- Ambient/Battery Temperature
- DRB Scan Tool Communication
Based on the information received from these various inputs, the TCM determines the appropriate
shift schedule and shift points, depending on the present operating conditions and driver demand.
This is possible through the control of various direct and indirect outputs.
Some examples of TCM direct outputs are:
- Transmission Control Relay
- Solenoids
- Torque Reduction Request
Some examples of TCM indirect outputs are:

Component Information > Diagrams > Page 4432
- Transmission Temperature (to PCM)
- PRNDL Position (to BCM)
In addition to monitoring inputs and controlling outputs, the TCM has other important
responsibilities and functions:
- Storing and maintaining Clutch Volume Indexes (CVI)
- Storing and selecting appropriate Shift Schedules
- System self-diagnostics
- Diagnostic capabilities (with DRB scan tool)
NOTE: If the TCM has been replaced, the "Quick Learn Procedure" must be performed. (Refer to
ELECTRONIC CONTROL MODULES/ TRANSMISSION CONTROL MODULE - STANDARD
PROCEDURE)
Battery Feed
A fused, direct battery feed to the TCM is used for continuous power. This battery voltage is
necessary to retain adaptive learn values in the TCM's RAM (Random Access Memory). When the
battery (B+) is disconnected, this memory is lost. When the battery (B+) is restored, this memory
loss is detected by the TCM and a Diagnostic Trouble Code (DTC) is set.
Clutch Volume Indexes (CVI)
An important function of the TCM is to monitor Clutch Volume Indexes (CVI). CVIs represent the
volume of fluid needed to compress a clutch pack.
The TCM monitors gear ratio changes by monitoring the Input and Output Speed Sensors. The
Input, or Turbine Speed Sensor sends an electrical signal to the TCM that represents input shaft
rpm. The Output Speed Sensor provides the TCM with output shaft speed information.
Fig. 14 Example Of CVI Calculation
By comparing the two inputs, the TCM can determine transmission gear position. This is important
to the CVI calculation because the TCM determines CVIs by monitoring how long it takes for a gear
change to occur (Fig. 14).
Gear ratios can be determined by using the DRB Scan Tool and reading the Input/Output Speed
Sensor values in the "Monitors" display. Gear ratio can be obtained by dividing the Input Speed
Sensor value by the Output Speed Sensor value.
For example, if the input shaft is rotating at 1000 rpm and the output shaft is rotating at 500 rpm,
then the TCM can determine that the gear ratio is 2:1. In direct drive (3rd gear), the gear ratio
changes to 1:1. The gear ratio changes as clutches are applied and released. By monitoring the
length of time it takes for the gear ratio to change following a shift request, the TCM can determine
the volume of fluid used to apply or release a friction element.

Component Information > Diagrams > Page 4433
The volume of transmission fluid needed to apply the friction elements are continuously updated for
adaptive controls. As friction material wears, the volume of fluid need to apply the element
increases.
Clutch Volumes
Certain mechanical problems within the input clutch assembly (broken return springs, out of
position snap rings, excessive clutch pack clearance, improper assembly, etc.) can cause
inadequate or out-of-range element volumes. Also, defective Input/Output Speed Sensors and
wiring can cause these conditions. The following chart identifies the appropriate clutch volumes
and when they are monitored/updated:
Shift Schedules
As mentioned earlier, the TCM has programming that allows it to select a variety of shift schedules.
Shift schedule selection is dependent on the following: Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level

Transmission Control System Relay: Description and Operation
DESCRIPTION
The relay is supplied fused B+ voltage, energized by the TCM, and is used to supply power to the
solenoid pack when the transmission is in normal operating mode.
OPERATION
When the relay is "off," no power is supplied to the solenoid pack and the transmission is in
"limp-in" mode. After a controller reset, the TCM energizes the relay. Prior to this, the TCM verifies
that the contacts are open by checking for no voltage at the switched battery terminals. After this is
verified, the voltage at the solenoid pack pressure switches is checked. After the relay is energized,
the TCM monitors the terminals to verify that the voltage is greater than 3 volts.

Overdrive Switch: Description and Operation
DESCRIPTION
The overdrive OFF (control) switch is located in the shift lever arm (Fig. 95). The switch is a
momentary contact device that signals the PCM to toggle current status of the overdrive function.
OPERATION
At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF
mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a
second time causes normal overdrive operation to be restored and the overdrive lamp to be turned
off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The
normal position for the control switch is the ON position. The switch must be in this position to
energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only
when the overdrive switch is turned to the OFF position, or when illuminated by the transmission
control module.

Transmission Position Switch/Sensor: Description and Operation
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted to the top of the valve body inside the
transmission.
The Transmission Range Sensor (TRS) has six switch contacts that:
- Determine shift lever position
- Supply ground to the Starter Relay in Park and Neutral only.
- Supply ground to the TCM for backup lamp control in Reverse only.
The TRS also has an integrated temperature sensor (thermistor) that communicates transmission
temperature to the TCM and PCM.
OPERATION
The Transmission Range Sensor (TRS) communicates shift lever position to the TCM as a
combination of open and closed switches. Each shift lever position has an assigned combination of
switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this
information and determines the appropriate transmission gear position and shift schedule.
There are many possible combinations of open and closed switches (codes). Seven of these
possible codes are related to gear position and five are recognized as "between gear" codes. This
results in many codes which should never occur. These are called "invalid" codes. An invalid code
will result in a DTC, and the TCM will then determine the shift lever position based on pressure
switch data. This allows reasonably normal transmission operation with a TRS failure.

Transmission Speed Sensor: Description and Operation Input Speed Sensor
DESCRIPTION
The Input and Output Speed Sensors are two-wire magnetic pickup devices that generate AC
signals as rotation occurs. They are mounted in the left side of the transmission case and are
considered primary inputs to the Transmission Control Module (TCM).
OPERATION
The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of
the input clutch hub pass by the sensor coil, an AC voltage is generated and sent to the TCM. The
TCM interprets this information as input shaft rpm.
The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by
rotation of the rear planetary carrier lugs. The TCM interprets this information as output shaft rpm.
The TCM compares the input and output speed signals to determine the following:
- Transmission gear ratio
- Speed ratio error detection
- CVI calculation
The TCM also compares the input speed signal and the engine speed signal to determine the
following:
- Torque converter clutch slippage
- Torque converter element speed ratio

Transmission Temperature Sensor/Switch: Description and Operation
DESCRIPTION
The transmission temperature sensor is a thermistor that is integral to the Transmission Range
Sensor (TRS).
OPERATION
The transmission temperature sensor is used by the TCM to sense the temperature of the fluid in
the sump. Since fluid temperature can affect transmission shift quality and convertor lock up, the
TCM requires this information to determine which shift schedule to operate in.
Calculated Temperature
A failure in the temperature sensor or circuit will result in calculated temperature being substituted
for actual temperature. Calculated temperature is a predicted fluid temperature which is calculated
from a combination of inputs: Battery (ambient) temperature
- Engine coolant temperature
- In-gear run time since start-up

ABS Light: Description and Operation
An Antilock Brake System (ABS) indicator is standard equipment on all instrument clusters. This
indicator serves both the standard equipment Rear Wheel Anti-Lock (RWAL) and optional
equipment 4-Wheel Anti-Lock (4WAL) brake systems. The ABS indicator is located in the
Information Center area of the instrument cluster, to the left of center. The ABS indicator consists
of a stencilled cutout of the International Control and Display Symbol icon for "Failure of Anti-lock
Braking System" in the opaque layer of the instrument cluster overlay. The dark outer layer of the
overlay prevents the indicator from being clearly visible when it is not illuminated. An amber lens
behind the cutout in the opaque layer of the overlay causes the icon to appear in amber through
the translucent outer layer of the overlay when it is illuminated from behind by a Light Emitting
Diode (LED) soldered onto the instrument cluster electronic circuit board. The ABS indicator is
serviced as a unit with the instrument cluster.
The ABS indicator gives an indication to the vehicle operator when the ABS system is faulty or
inoperative. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Controller
Antilock Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The ABS
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the ABS indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the ABS indicator is
illuminated by the cluster for about two seconds as a bulb test.
- ABS Lamp-ON Message - Each time the cluster receives a lamp-ON message from the CAB, the
ABS indicator will be illuminated. The indicator remains illuminated until the cluster receives a
lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position,
whichever occurs first.
- Communication Error - If the cluster receives no lamp-ON or lamp-OFF messages from the CAB
for six consecutive seconds, the ABS indicator is illuminated. The indicator remains illuminated until
the cluster receives a valid message from the CAB, or until the ignition switch is turned to the OFF
position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the ABS indicator
will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
- ABS Diagnostic Test - The ABS indicator is blinked ON and OFF by lamp-ON and lamp-OFF
messages from the CAB during the performance of the ABS diagnostic tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. If the CAB sends a lamp-ON message after the bulb test, it indicates that the
CAB has detected a system malfunction and/or that the ABS system has become inoperative. The
CAB will store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ABS
indicator fails to light due to an open or short in the cluster ABS indicator circuit, the cluster sends a
message notifying the CAB of the condition, and the CAB will store a DTC. For proper diagnosis of
the antilock brake system, the CAB, the PCI data bus, or the message inputs to the instrument
cluster that control the ABS indicator, a DRB III scan tool is required. Refer to the appropriate
diagnostic information.

Controller Antilock Brake: Description and Operation
CONTROLLER REAR WHEEL ANTILOCK BRAKES
Fig. 3 RWAL Cab
The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitor the RWAL brake system for proper operation.
- Control the RWAL valve solenoids.
Fig. 4 CAB/HCU
The CAB is mounted on the top of the hydraulic control unit. The CAB operates the ABS system
and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition
switch in the RUN position.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB. For axle type refer to Differential and Driveline.
System Self-test When the ignition switch is turned-ON the microprocessor RAM and ROM are
tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is
possible the DTC will not be stored in memory if the error has occurred in the RAM module were
the DTC's are

stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which
signals the RAM to store the DTC.
The CAB contains a self check program that illuminates the ABS warning light when a system fault
is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB
scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50
times. Stored faults are not erased if the battery is disconnected.
CAB Inputs The CAB continuously monitors the speed of the differential ring gear by monitoring
signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency
when it recognizes the ring gear is decelerating too rapidly. The CAB monitors the following inputs
to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB Outputs The CAB controls the following outputs for antilock braking and brake warning

Hydraulic Control Assembly - Antilock Brakes: Description and Operation Four Wheel Antilock
Brake System
DESCRIPTION
The hydraulic control unit (HCU) consists of a valve body, pump, two accumulators and a motor.
The assembly is mounted on the driver side inner fender under the hood.
OPERATION
The pump, motor, and accumulators are combined into an assembly attached to the valve body.
The accumulators store the extra fluid which had to be dumped from the brakes. This is done to
prevent the wheels from locking up. The pump provides the fluid volume needed and is operated
by a DC type motor. The motor is controlled by the CAB.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
The valve body contains the solenoid valves. The valves modulate brake pressure during antilock
braking and are controlled by the CAB.
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed. The valves are not
static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and
deceleration.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
decrease, pressure hold, and pressure increase. The valves are all contained in the valve body
portion of the HCU.
PRESSURE DECREASE
The inlet valve is closed and the outlet valve is opened during the pressure decrease cycle .
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the
brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the
return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to
prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
PRESSURE HOLD
Both solenoid valves are closed in the pressure hold cycle . Fluid apply pressure in the control
channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor inputs
indicate a pressure change is necessary.
PRESSURE INCREASE
The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The
pressure increase cycle is used to counteract unequal

wheel speeds. This cycle controls re-application of fluid apply pressure due to changing road
surfaces or wheel speed.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation Rear Wheel Antilock
Brakes
DESCRIPTION
The valve is located on the drivers side inner fender under the hood. The valve modulates
hydraulic pressure to the rear brakes during an RWAL stop.
OPERATION
If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation
solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver
induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel
lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump
solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small
amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the
accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure
venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump
valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The
system will switch to normal braking once wheel locking tendencies are no longer present.
A predetermined maximum number of consecutive dump cycles can be performed during any
RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If
during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This
signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB
will then reset the dump cycle counter in anticipation of the next RWAL stop. Additionally, any fluid
stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and
return to the master cylinder.
A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the
isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output
circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and
RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without
antilock control over rear brake pressure.

Wheel Speed Sensor: Description and Operation Wheel Speed Sensor
OPERATION
The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor
sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic
induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary
magnetic WSS.
When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring tooth
approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic field to
cut across the sensor's windings. This, in turn causes current to flow through the WSS circuit in
one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic lines of
force collapse cutting the winding in the opposite direction. This causes the current to flow in the
opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is
generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It
then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB
continues to monitor the frequency to determine a deceleration rate that would indicate a possible
wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by:
- Magnetic field strength; the stronger the magnetic field, the stronger the signal
- Number of windings in the sensor; more windings provide a stronger signal
- Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
- Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring/tone
wheel, the stronger the signal will be
The rear WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch

The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is

Brake Warning Indicator: Description and Operation
BRAKE/PARK BRAKE INDICATOR
A brake indicator is standard equipment on all instrument clusters. The brake indicator is located in
the Information Center area of the instrument cluster; to the right of center. The brake indicator
consists of a stenciled cutout of the word "BRAKE" and the International Control and Display
Symbol icons for "Brake Failure" and "Parking Brake" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the
"BRAKE" text and the two icons to appear in red through the translucent outer layer of the overlay
when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied, or
when there are certain brake hydraulic system malfunctions. This indicator is controlled by a
transistor on the instrument cluster circuit board based upon cluster programming, and electronic
messages received by the cluster from the Central Timer Module (CTM) and the Controller Antilock
Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The brake
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the brake indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the brake indicator is
illuminated by the instrument cluster for about four seconds as a bulb test.
- Brake Lamp-On Message - Each time the cluster receives a lamp-on message from the CTM or
the CAB, the brake indicator will be illuminated. If the park brake is applied or not fully released, or
if the pressures in the two halves of the split brake hydraulic system are not equal with the ignition
switch in the ON position, the brake indicator is illuminated solid. The brake indicator will blink ON
and OFF repeatedly when the park brake is applied or not fully released and the ignition switch is in
the ON position if the automatic transmission is not in Park or Neutral. The indicator remains
illuminated until the cluster receives lamp-off messages from both the CTM and the CAB, or until
the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the CTM circuitry through the park brake switch sense circuit whenever the park brake is applied or
not fully released. The CTM then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. The brake pressure switch on the brake combination valve provides a hard
wired ground input to the CAB circuitry through the brake pressure switch sense circuit whenever
the pressures in the two halves of the split brake hydraulic system are unequal. The CAB then
sends the proper lamp-ON or lamp-OFF messages to the instrument cluster. If the CAB sends a
lamp-ON message after the bulb test, it indicates that the CAB has detected a brake hydraulic
system malfunction and/or that the ABS system has become inoperative. The CAB will store a
Diagnostic Trouble Code (DTC) for any malfunction it detects. The park brake switch input to the
CTM and the brake pressure switch input to the CAB can be diagnosed using conventional
diagnostic tools and methods. For proper diagnosis of the antilock brake system, the CTM, the
CAB, the PCI data bus, or the message inputs to the instrument cluster that control the brake
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Brake Rotor/Disc: Testing and Inspection
DIAGNOSIS AND TESTING - DISC BRAKE ROTOR
The rotor braking surfaces should not be refinished unless necessary. Light surface rust and scale
can be removed with a lathe equipped with dual sanding discs. The rotor surfaces can be restored
by machining in a disc brake lathe if surface scoring and wear are light. Replace the rotor under the
following conditions: severely scored
- tapered
- hard spots
- cracked
- below minimum thickness
ROTOR MINIMUM THICKNESS
Measure rotor thickness at the center of the brake shoe contact surface. Replace the rotor if worn
below minimum thickness, or if machining would reduce thickness below the allowable minimum.
Rotor minimum thickness is usually specified on the rotor hub. The specification is either stamped
or cast into the hub surface.
ROTOR RUNOUT
Check rotor lateral runout with dial indicator C-3339. Excessive lateral runout will cause brake
pedal pulsation and rapid, uneven wear of the brake shoes. Position the dial indicator plunger
approximately 25.4 mm (1 inch) inward from the rotor edge. Maximum allowable rotor runout is
0.102 mm(0.004 inch).
ROTOR THICKNESS VARIATION
Variations in rotor thickness will cause pedal pulsation, noise and shudder.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Brakes and Traction Control > Disc Brake System > Brake Rotor/Disc > Component
Information > Specifications > Page 4607
Measure rotor thickness at 6 to 12 points around the rotor face. Position the micrometer
approximately 25.4 mm (1 inch) frown the rotor outer circumference for each measurement.
Thickness should not vary by more than 0.013 mm (0.0005 inch) from point-to-point on the rotor.
Machine or replace the rotor if necessary.

Brake Drum: Testing and Inspection
DIAGNOSIS AND TESTING - BRAKE DRUM
The maximum allowable diameter of the drum braking surface is indicated on the drum outer edge.
Generally, a drum can be machined to a maximum of 1.52 mm (0.060 inch) oversize. Always
replace the drum if machining would cause drum diameter to exceed the size limit indicated on the
drum.
BRAKE DRUM RUNOUT
Measure drum diameter and runout with an accurate gauge. The most accurate method of
measurement involves mounting the drum in a brake lathe and checking variation and runout with a
dial indicator. Variations in drum diameter should not exceed 0.076 mm (0.003 inch). Drum runout
should not exceed 0.20 mm (0.008 inch) out of round. Machine the drum if runout or variation
exceed these values. Replace the drum if machining causes the drum to exceed the maximum
allowable diameter.

Brake Drum: Service and Repair
STANDARD PROCEDURE - BRAKE DRUM MACHINING
The brake drums can be machined on a drum lathe when necessary. Initial machining cuts should
be limited to 0.12 - 0.20 mm (0.005 - 0.008 inch) at a time as heavier feed rates can produce taper
and surface variation. Final finish cuts of 0.025 to 0.038 mm (0.001 to 0.0015 inch) are
recommended and will generally provide the best surface finish. Be sure the drum is securely
mounted in the lathe before machining operations. A damper strap should always be used around
the drum to reduce vibration and avoid chatter marks. The maximum allowable diameter of the
drum braking surface is stamped or cast into the drum outer edge.
CAUTION: Replace the drum if machining will cause the drum to exceed the maximum allowable
diameter.

Wheel Cylinder: Service and Repair Cleaning and Inspection
CLEANING
Clean the cylinder and pistons with clean brake fluid or brake cleaner only. Do not use any other
cleaning agents. Dry the cylinder and pistons with compressed air. Do not use rags or shop towels
to dry the cylinder components. Lint from cloth material will adhere to the cylinder bores and
pistons.
INSPECTION
Inspect the cylinder bore. Light discoloration and dark stains in the bore are normal and will not
impair cylinder operation. The cylinder bore can be lightly polished but only with crocus cloth.
Replace the cylinder if the bore is scored, pitted or heavily corroded. Honing the bore to restore the
surface is not recommended. Inspect the cylinder pistons. The piston surfaces should be smooth
and free of scratches, scoring and corrosion. Replace the pistons if worn, scored, or corroded. Do
attempt to restore the surface by sanding or polishing. Discard the old piston cups and the spring
and expander. These parts are not reusable. The original dust boots may be reused but only if they
are in good condition.

Brake Hose/Line: Testing and Inspection
DIAGNOSIS AND TESTING - BRAKE LINE AND HOSES
Flexible rubber hose is used at both front brakes and at the rear axle junction block. Inspect the
hoses whenever the brake system is serviced, at every engine oil change, or whenever the vehicle
is in for service. Inspect the hoses for surface cracking, scuffing, or worn spots. Replace any brake
hose immediately if the fabric casing of the hose is exposed due to cracks or abrasions. Also check
brake hose installation. Faulty installation can result in kinked, twisted hoses, or contact with the
wheels and tires or other chassis components. All of these conditions can lead to scuffing, cracking
and eventual failure. The steel brake lines should be inspected periodically for evidence of
corrosion, twists, kinks, leaks, or other damage. Heavily corroded lines will eventually rust through
causing leaks. In any case, corroded or damaged brake lines should be replaced. Factory
replacement brake lines and hoses are recommended to ensure quality, correct length and
superior fatigue life. Care should be taken to make sure that brake line and hose mating surfaces
are clean and free from nicks and burrs. Also remember that right and left brake hoses are not
interchangeable. Use new copper seal washers at all caliper connections. Be sure brake line
connections are properly made (not cross threaded) and tightened to recommended torque.

Valve > Component Information > Description and Operation
Brake Proportioning/Combination Valve: Description and Operation
DESCRIPTION
The combination valve contains a pressure differential valve and switch and a proportioning valve.
The combination valve/proportioning valve are not repairable and must be replaced as an
assembly. The pressure differential switch is connected to the brake warning lamp. The switch is
triggered by movement of the switch valve. The purpose of the switch is to monitor fluid pressure in
the separate front/rear brake hydraulic circuits. A decrease or loss of fluid pressure in either
hydraulic circuit will cause the switch valve to shuttle forward or rearward in response to the
pressure differential. Movement of the switch valve will push the switch plunger upward. This
closes the switch internal contacts completing the electrical circuit to the warning lamp. The switch
valve may remain in an actuated position until repair restores system pressures to normal levels.
OPERATION
The combination valve contains a pressure differential valve and switch and a proportioning valve.
The combination valve/proportioning valve are not repairable and must be replaced as an
assembly. The proportioning valve is used to balance front-rear brake action at high decelerations.
The valve allows normal fluid pressure during moderate braking. The valve only controls fluid
pressure during high decelerations brake stops, when a percentage of rear weight is transferred to
the front wheels.

The hydraulic control unit (HCU) consists of a valve body, pump, two accumulators and a motor.
The assembly is mounted on the driver side inner fender under the hood.
OPERATION
The pump, motor, and accumulators are combined into an assembly attached to the valve body.
The accumulators store the extra fluid which had to be dumped from the brakes. This is done to
prevent the wheels from locking up. The pump provides the fluid volume needed and is operated
by a DC type motor. The motor is controlled by the CAB.
During normal braking, the HCU solenoid valves and pump are not activated. The master cylinder
and power booster operate the same as a vehicle without an ABS brake system.
The valve body contains the solenoid valves. The valves modulate brake pressure during antilock
braking and are controlled by the CAB.
The HCU provides three channel pressure control to the front and rear brakes. One channel
controls the rear wheel brakes in tandem. The two remaining channels control the front wheel
brakes individually.
During antilock braking, the solenoid valves are opened and closed as needed. The valves are not
static. They are cycled rapidly and continuously to modulate pressure and control wheel slip and
deceleration.
During antilock braking, solenoid valve pressure modulation occurs in three stages, pressure
decrease, pressure hold, and pressure increase. The valves are all contained in the valve body
portion of the HCU.
PRESSURE DECREASE
The inlet valve is closed and the outlet valve is opened during the pressure decrease cycle .
A pressure decrease cycle is initiated when speed sensor signals indicate high wheel slip at one or
more wheels. At this point, the CAB closes the inlet to prevent the driver from further increasing the
brake pressure and locking the brakes. The CAB then opens the outlet valve, which also opens the
return circuit to the accumulators. Fluid pressure is allowed to bleed off (decrease) as needed to
prevent wheel lock.
Once the period of high wheel slip has ended, the CAB closes the outlet valve and begins a
pressure increase or hold cycle as needed.
PRESSURE HOLD
Both solenoid valves are closed in the pressure hold cycle . Fluid apply pressure in the control
channel is maintained at a constant rate. The CAB maintains the hold cycle until sensor inputs
indicate a pressure change is necessary.
PRESSURE INCREASE
The inlet valve is open and the outlet valve is closed during the pressure increase cycle. The
pressure increase cycle is used to counteract unequal

surfaces or wheel speed.

Hydraulic Control Assembly - Antilock Brakes: Description and Operation Rear Wheel Antilock
Brakes
DESCRIPTION
The valve is located on the drivers side inner fender under the hood. The valve modulates
hydraulic pressure to the rear brakes during an RWAL stop.
OPERATION
If the CAB senses that rear wheel speed deceleration is excessive, it will energize an isolation
solenoid by providing battery voltage to the solenoid. This prevents a further increase of driver
induced brake pressure to the rear wheels. If this initial action is not enough to prevent rear wheel
lock-up, the CAB will momentarily energize a dump solenoid (the CAB energizes the dump
solenoid by providing battery voltage to the solenoid). This opens the dump valve to vent a small
amount of isolated rear brake pressure to an accumulator. The action of fluid moving to the
accumulator reduces the isolated brake pressure at the wheel cylinders. The dump (pressure
venting) cycle is limited to very short time periods (milliseconds). The CAB will pulse the dump
valve until rear wheel deceleration matches the desired slip rate programmed into the CAB. The
system will switch to normal braking once wheel locking tendencies are no longer present.
A predetermined maximum number of consecutive dump cycles can be performed during any
RWAL stop. If excessive dump cycles occur, a DTC will be set and stored in the CAB memory. If
during a RWAL stop, the driver releases the brake pedal, the reset switch contacts will open. This
signal to the CAB is an indication that pressure has equalized across the RWAL valve. The CAB
will then reset the dump cycle counter in anticipation of the next RWAL stop. Additionally, any fluid
stored in the accumulator will force its way past the dump valve, back into the hydraulic circuit and
return to the master cylinder.
A fuse internal to the CAB, provides a fail-safe device which prevents unwanted control over the
isolation and dump solenoids. The fuse is in series with the isolation and dump solenoids output
circuits. If the internal fuse is open, the CAB cannot provide voltage to energize either solenoid and
RWAL stops are prevented. If the fuse is open, the braking system will operate normally but without
antilock control over rear brake pressure.

Brake Master Cylinder: Description and Operation
DESCRIPTION
A two-piece master cylinder is used on all models. The cylinder body containing the primary and
secondary pistons is made of aluminum. The removable fluid reservoir is made of nylon reinforced
with glass fiber. The reservoir stores reserve brake fluid for the hydraulic brake circuits. The
reservoir is the only serviceable component. The fluid compartments of the nylon reservoir are
interconnected to permit fluid level equalization. However, the equalization feature does not affect
circuit separation in the event of a front or rear brake malfunction. The reservoir compartments will
retain enough fluid to operate the functioning hydraulic circuit. Care must be exercised when
removing/installing the master cylinder connecting lines. The threads in the cylinder fluid ports can
be damaged if care is not exercised. Start all brake line fittings by hand to avoid cross threading.
The cylinder reservoir can be replaced when necessary. However, the aluminum body section of
the master cylinder is not a repairable component.
NOTE: If diagnosis indicates that an internal malfunction has occurred, the aluminum body section
must be replaced as an assembly.
OPERATION
The master cylinder bore contains a primary and secondary piston. The primary piston supplies
hydraulic pressure to the front brakes. The secondary piston supplies hydraulic pressure to the rear
brakes.

Brake Master Cylinder: Testing and Inspection
DIAGNOSIS AND TESTING - MASTER CYLINDER/POWER BOOSTER
(1) Start engine and check booster vacuum hose connections. A hissing noise indicates vacuum
leak. Correct any vacuum leak before proceeding. (2) Stop engine and shift transmission into
Neutral. (3) Pump brake pedal until all vacuum reserve in booster is depleted. (4) Press and hold
brake pedal under light foot pressure. The pedal should hold firm, if the pedal falls away master
cylinder is faulty (internal
leakage).
(5) Start engine and note pedal action. It should fall away slightly under light foot pressure then
hold firm. If no pedal action is discernible, power
booster, vacuum supply, or vacuum check valve is faulty. Proceed to the POWER BOOSTER
VACUUM TEST.
(6) If the POWER BOOSTER VACUUM TEST passes, rebuild booster vacuum reserve as follows:
Release brake pedal. Increase engine speed to
1500 rpm, close the throttle and immediately turn off ignition to stop engine.
(7) Wait a minimum of 90 seconds and try brake action again. Booster should provide two or more
vacuum assisted pedal applications. If vacuum
assist is not provided, booster is faulty.
POWER BOOSTER VACUUM TEST
(1) Connect vacuum gauge to booster check valve with short length of hose and T-fitting . (2) Start
and run engine at curb idle speed for one minute. (3) Observe the vacuum supply. If vacuum
supply is not adequate, repair vacuum supply. (4) Clamp hose shut between vacuum source and
check valve. (5) Stop engine and observe vacuum gauge. (6) If vacuum drops more than one inch
HG (33 millibars) within 15 seconds, booster diaphragm or check valve is faulty.
POWER BOOSTER CHECK VALVE TEST
(1) Disconnect vacuum hose from check valve. (2) Remove check valve and valve seal from
booster. (3) Use a hand operated vacuum pump for test.

Wheel Cylinder: Service and Repair Cleaning and Inspection
CLEANING
Clean the cylinder and pistons with clean brake fluid or brake cleaner only. Do not use any other
cleaning agents. Dry the cylinder and pistons with compressed air. Do not use rags or shop towels
to dry the cylinder components. Lint from cloth material will adhere to the cylinder bores and
pistons.
INSPECTION
Inspect the cylinder bore. Light discoloration and dark stains in the bore are normal and will not
impair cylinder operation. The cylinder bore can be lightly polished but only with crocus cloth.
Replace the cylinder if the bore is scored, pitted or heavily corroded. Honing the bore to restore the
surface is not recommended. Inspect the cylinder pistons. The piston surfaces should be smooth
and free of scratches, scoring and corrosion. Replace the pistons if worn, scored, or corroded. Do
attempt to restore the surface by sanding or polishing. Discard the old piston cups and the spring
and expander. These parts are not reusable. The original dust boots may be reused but only if they
are in good condition.

Parking Brake Warning Lamp: Description and Operation
BRAKE/PARK BRAKE INDICATOR
A brake indicator is standard equipment on all instrument clusters. The brake indicator is located in
the Information Center area of the instrument cluster; to the right of center. The brake indicator
consists of a stenciled cutout of the word "BRAKE" and the International Control and Display
Symbol icons for "Brake Failure" and "Parking Brake" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the
"BRAKE" text and the two icons to appear in red through the translucent outer layer of the overlay
when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied, or
when there are certain brake hydraulic system malfunctions. This indicator is controlled by a
transistor on the instrument cluster circuit board based upon cluster programming, and electronic
messages received by the cluster from the Central Timer Module (CTM) and the Controller Antilock
Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The brake
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the brake indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the brake indicator is
illuminated by the instrument cluster for about four seconds as a bulb test.
- Brake Lamp-ON Message - Each time the cluster receives a lamp-on message from the CTM or
the CAB, the brake indicator will be illuminated. If the park brake is applied or not fully released, or
if the pressures in the two halves of the split brake hydraulic system are not equal with the ignition
switch in the ON position, the brake indicator is illuminated solid. The brake indicator will blink ON
and OFF repeatedly when the park brake is applied or not fully released and the ignition switch is in
the ON position if the automatic transmission is not in Park or Neutral. The indicator remains
illuminated until the cluster receives lamp-OFF messages from both the CTM and the CAB, or until
the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the CTM circuitry through the park brake switch sense circuit whenever the park brake is applied or
not fully released. The CTM then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. The brake pressure switch on the brake combination valve provides a hard
wired ground input to the CAB circuitry through the brake pressure switch sense circuit whenever
the pressures in the two halves of the split brake hydraulic system are unequal. The CAB then
sends the proper lamp-ON or lamp-OFF messages to the instrument cluster. If the CAB sends a
lamp-ON message after the bulb test, it indicates that the CAB has detected a brake hydraulic
system malfunction and/or that the ABS system has become inoperative. The CAB will store a
Diagnostic Trouble Code (DTC) for any malfunction it detects. The park brake switch input to the
CTM and the brake pressure switch input to the CAB can be diagnosed using conventional
diagnostic tools and methods. For proper diagnosis of the antilock brake system, the CTM, the
CAB, the PCI data bus, or the message inputs to the instrument cluster that control the brake
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Controller Antilock Brake: Description and Operation
CONTROLLER REAR WHEEL ANTILOCK BRAKES
Fig. 3 RWAL Cab
The Controller Antilock Brakes (CAB) is a microprocessor which handles testing, monitoring and
controlling the ABS brake system operation. The CAB functions are: Perform self-test diagnostics.
- Monitor the RWAL brake system for proper operation.
- Control the RWAL valve solenoids.
Fig. 4 CAB/HCU
The CAB is mounted on the top of the hydraulic control unit. The CAB operates the ABS system
and is separate from other vehicle electrical circuits. CAB voltage source is through the ignition
switch in the RUN position.
NOTE: If the CAB needs to be replaced, the rear axle type and tire revolutions per mile must be
programed into the new CAB. For axle type refer to Differential and Driveline.
System Self-test When the ignition switch is turned-ON the microprocessor RAM and ROM are
tested. If an error occurs during the test, a DTC will be set into the RAM memory. However it is
possible the DTC will not be stored in memory if the error has occurred in the RAM module were
the DTC's are

stored. Also it is possible a DTC may not be stored if the error has occurred in the ROM which
signals the RAM to store the DTC.
The CAB contains a self check program that illuminates the ABS warning light when a system fault
is detected. Faults are stored in a diagnostic program memory and are accessible with the DRB
scan tool.
ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50
times. Stored faults are not erased if the battery is disconnected.
CAB Inputs The CAB continuously monitors the speed of the differential ring gear by monitoring
signals generated by the rear wheel speed sensor. The CAB determines a wheel locking tendency
when it recognizes the ring gear is decelerating too rapidly. The CAB monitors the following inputs
to determine when a wheel locking tendency may exists: Rear Wheel Speed Sensor
- Brake Lamp Switch
- Brake Warning Lamp Switch
- Reset Switch
- 4WD Switch (If equipped)
CAB Outputs The CAB controls the following outputs for antilock braking and brake warning
information: RWAL Valve
- ABS Warning Lamp

DESCRIPTION
The rear Wheel Speed Sensor (WSS) is mounted in the rear differential housing.
The exciter ring is press fitted onto the differential carrier next to the final drive ring gear. For
replacement procedure of the exciter ring.

Wheel Speed Sensor: Description and Operation Wheel Speed Sensor
OPERATION
The WSS consists of a magnet surrounded by windings from a single strand of wire. The sensor
sends a small AC signal to the CAB. This signal is generated by magnetic induction. The magnetic
induction is created when a toothed sensor ring (exciter ring or tone wheel) passes the stationary
magnetic WSS.
When the ring gear is rotated, the exciter ring passes the tip of the WSS. As the exciter ring tooth
approaches the tip of the WSS, the magnetic lines of force expand, causing the magnetic field to
cut across the sensor's windings. This, in turn causes current to flow through the WSS circuit in
one direction. When the exciter ring tooth moves away from the sensor tip, the magnetic lines of
force collapse cutting the winding in the opposite direction. This causes the current to flow in the
opposite direction. Every time a tooth of the exciter ring passes the tip of the WSS, an AC signal is
generated. Each AC signal (positive to negative signal or sinewave) is interpreted by the CAB. It
then compares the frequency of the sinewave to a time value to calculate vehicle speed. The CAB
continues to monitor the frequency to determine a deceleration rate that would indicate a possible
wheel-locking tendency.
The signal strength of any magnetic induction sensor is directly affected by:
- Magnetic field strength; the stronger the magnetic field, the stronger the signal
- Number of windings in the sensor; more windings provide a stronger signal
- Exciter ring speed; the faster the exciter ring/tone wheel rotates, the stronger the signal will be
- Distance between the exciter ring teeth and WSS; the closer the WSS is to the exciter ring/tone
wheel, the stronger the signal will be
The rear WSS is not adjustable. A clearance specification has been established for manufacturing
tolerances. If the clearance is not within these specifications, then either the WSS or other
components may be damaged. The clearance between the WSS and the exciter ring is 0.005 0.050 inch

The assembly plant performs a "Rolls Test" on every vehicle that leaves the assembly plant. One
of the test performed is a test of the WSS. To properly test the sensor, the assembly plant connects
test equipment to the Data Link Connector (DLC). This connector is located to the right of the
steering column and attached to the lower portion of the instrument panel. The rolls test terminal is
spliced to the WSS circuit. The vehicle is then driven on a set of rollers and the WSS output is
monitored for proper operation.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

Fig. 11 Starter Relay
The starter relay (Fig. 11) is located in Power Distribution Center (PDC). Refer to PDC cover for
relay identification and location.
1. Remove starter relay from PDC. 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12V battery to terminals 85 and 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage
and should be hot at all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to ON position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required.

Battery Cable: Description and Operation
Fig. 20 Battery Cables
The battery cables (Fig. 20) are large gauge, stranded copper wires sheathed within a heavy
plastic or synthetic rubber insulating jacket. The wire used in the battery cables combines excellent
flexibility and reliability with high electrical current carrying capacity. Refer to Wiring Diagrams for
the location of the proper battery cable wire gauge information.
The battery cables cannot be repaired and, if damaged or faulty they must be replaced. Both the
battery positive and negative cables are available for service replacement only as a unit with the
battery positive cable wire harness or the battery negative cable wire harness, which may include
portions of the wiring circuits for the generator and other components on some models. Refer to
Wiring Diagrams for the location of more information on the various wiring circuits included in the
battery cable wire harnesses for the vehicle being serviced.
The battery cables feature a stamped brass clamping type female battery terminal crimped onto
one end of the battery cable wire and then solder-dipped. A square headed pinch-bolt and hex nut
are installed at the open end of the female battery terminal clamp. The battery positive cable also
includes a red molded rubber protective cover for the female battery terminal clamp. Large eyelet
type terminals are crimped onto the opposite end of the battery cable wire and then solder-dipped.
The battery positive cable wires have a red insulating jacket to provide visual identification and
feature a larger female battery terminal clamp to allow connection to the larger battery positive
terminal post. The battery negative cable wires have a black insulating jacket and a smaller female
battery terminal clamp.
The battery cables connect the battery terminal posts to the vehicle electrical system. These cables
also provide a return path for electrical current generated by the charging system for restoring the
voltage potential of the battery. The female battery terminal clamps on the ends of the battery cable
wires provide a strong and reliable connection of the battery cable to the battery terminal posts.
The terminal pinch bolts allow the female terminal clamps to be tightened around the male terminal
posts on the top of the battery. The eyelet terminals secured to the ends of the battery cable wires
opposite the female battery terminal clamps provide secure and reliable connection of the battery
to the vehicle electrical system.

Battery Cable: Testing and Inspection
A voltage drop test will determine if there is excessive resistance in the battery cable terminal
connections or the battery cables. If excessive resistance is found in the battery cable connections,
the connection point should be disassembled, cleaned of all corrosion or foreign material, then
reassembled. Following reassembly, check the voltage drop for the battery cable connection and
the battery cable again to confirm repair.
When performing the voltage drop test, it is important to remember that the voltage drop is giving
an indication of the resistance between the two points at which the voltmeter probes are attached.
EXAMPLE: When testing the resistance of the battery positive cable, touch the voltmeter leads to
the battery positive cable terminal clamp and to the battery positive cable eyelet terminal at the
starter solenoid B(+) terminal stud. If you probe the battery positive terminal post and the battery
positive cable eyelet terminal at the starter solenoid B(+) terminal stud, you are reading the
combined voltage drop in the battery positive cable terminal clamp-to-terminal post connection and
the battery positive cable.

Battery Temperature Sensor: Description and Operation
The Battery Temperature Sensor (BTS) is attached to the battery tray located under the battery.
The BTS is used to determine the battery temperature and control battery charging rate. This
temperature data, along with data from monitored line voltage, is used by the PCM to vary the
battery charging rate. System voltage will be higher at colder temperatures and is gradually
reduced at warmer temperatures.
The PCM sends 5 volts to the sensor and is grounded through the sensor return line. As
temperature increases, resistance in the sensor decreases and the detection voltage at the PCM
increases.
The BTS is also used for OBD II diagnostics. Certain faults and OBD II monitors are either enabled
or disabled, depending upon BTS input (for example, disable purge and enable Leak Detection
Pump (LDP) and 02 sensor heater tests). Most OBD II monitors are disabled below 20 degrees F.

Alternator: Description and Operation
The generator is belt-driven by the engine using a serpentine type drive belt. It is serviced only as a
complete assembly. If the generator fails for any reason, the entire assembly must be replaced.
As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a
current into the windings of the stator coil. Once the generator begins producing sufficient current, it
also provides the current needed to energize the rotor.
The Y type stator winding connections deliver the induced AC current to 3 positive and 3 negative
diodes for rectification. From the diodes, rectified DC current is delivered to the vehicle electrical
system through the generator battery terminal.
Although the generators appear the same externally, different generators with different output
ratings are used on this vehicle. Be certain that the replacement generator has the same output
rating and part number as the original unit. Refer to Generator Ratings in the Specifications for
amperage ratings and part numbers.
Noise emitting from the generator may be caused by: worn, loose or defective bearings; a loose or
defective drive pulley; incorrect, worn, damaged or misadjusted fan drive belt; loose mounting
bolts; a misaligned drive pulley or a defective stator or diode.

Voltage Regulator: Description and Operation
The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage
regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced
separately. If replacement is necessary, the PCM must be replaced.
The amount of DC current produced by the generator is controlled by EVR circuitry contained
within the PCM. This circuitry is connected in series with the generators second rotor field terminal
and its ground.
Voltage is regulated by cycling the ground path to control the strength of the rotor magnetic field.
The EVR circuitry monitors system line voltage (B+) and battery temperature (refer to Battery
Temperature Sensor for more information). It then determines a target charging voltage. If sensed
battery voltage is 0.5 volts or lower than the target voltage, the PCM grounds the field winding until
sensed battery voltage is 0.5 volts above target voltage. A circuit in the PCM cycles the ground
side of the generator field up to 100 times per second (100Hz), but has the capability to ground the
field control wire 100% of the time (full field) to achieve the target voltage. If the charging rate
cannot be monitored (limp-in), a duty cycle of 25% is used by the PCM in order to have some
generator output. Also refer to Charging System Operation for additional information.

Starter Motor: Description and Operation
The starter motors used for this engine are not interchangeable with the starter motors used for the
other available engines for this model.
This engine starter motor is mounted with two bolts to the transmission housing on the left side of
the engine.
The electric motors of both starters have four brushes contacting the motor commutator. The
starter motors use four electromagnetic field coils wound around four pole shoes. The starter
motors are rated at 1.4 kilowatts (about 1.9 horsepower) output at 12 volts.
The starter motors are serviced only as a unit with starter solenoids, and cannot be repaired. If
either component is faulty or damaged, the entire starter motor and starter solenoid unit must be
replaced.
The starter motor is equipped with a gear reduction (intermediate transmission) system. The gear
reduction system consists of a gear that is integral to the output end of the electric motor armature
shaft that is in continual engagement with a larger gear that is splined to the input end of the starter
pinion gear shaft. This feature makes it possible to reduce the dimensions of the starter. At the
same time, it allows higher armature rotational speed, and delivers increased torque through the
starter pinion gear to the starter ring gear.
The starter motor is activated by an integral heavy duty starter solenoid switch mounted to the
overrunning clutch housing. This electromechanical switch connects and disconnects the feed of
battery voltage to the starter motor, and actuates a shift fork that engages and disengages the
starter pinion gear with the starter ring gear.
The starter motor uses an overrunning clutch and starter pinion gear unit to engage and drive the
gears on the flywheel (or flywheel ring gear).

Starter Relay: Description and Operation
The starter relay is an electromechanical device that switches battery current to the pull-in coil of
the starter solenoid when ignition switch is turned to Start position. The starter relay is located in
the Power Distribution Center (PDC) in the engine compartment. See PDC cover for relay
identification and location.
The starter relay is a International Standards Organization (ISO) relay. Relays conforming to ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions.
The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When electromagnetic coil is energized, it
draws the movable contact away from normally closed fixed contact, and holds it against the other
(normally open) fixed contact.
When electromagnetic coil is de-energized, spring pressure returns movable contact to normally
closed position. The resistor or diode is connected in parallel with electromagnetic coil within relay,
and helps to dissipate voltage spikes produced when coil is de-energized.

The starter relay (Fig. 11) is located in Power Distribution Center (PDC). Refer to PDC cover for
relay identification and location.
1. Remove starter relay from PDC. 2. A relay in de-energized position should have continuity
between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace faulty relay. 4. Connect 12V battery to terminals 85 and 86. There should
now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, perform Relay Circuit Test that follows. If not OK, replace faulty relay.
Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage
and should be hot at all times. If OK, go to Step 2. If not OK, repair
open circuit to fuse in PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to common feed terminal (30) in the
energized position. This terminal supplies battery voltage
to starter solenoid field coils. There should be continuity between cavity for relay terminal 87 and
starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair open circuit to starter
solenoid as required.
4. The coil battery terminal (86) is connected to electromagnet in relay. It is energized when ignition
switch is held in Start position. On vehicles with
manual transmission, clutch pedal must be fully depressed for this test. Check for battery voltage at
cavity for relay terminal 86 with ignition switch in Start position, and no voltage when ignition switch
is released to ON position. If OK, go to Step 5. If not OK with automatic transmission, check for
open or short circuit to ignition switch and repair, if required. If circuit to ignition switch is OK, refer
to Ignition Switch and Key Lock Cylinder. If not OK with a manual transmission, check circuit
between relay and clutch pedal position switch for open or a short.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. On vehicles with
manual transmission, it is grounded at all times. On
vehicles with automatic transmission, it is grounded through park/neutral position switch only when
gearshift selector lever is in Park or Neutral positions. Check for continuity to ground at cavity for
relay terminal 85. If not OK with manual transmission, repair circuit to ground as required. If not OK
with automatic transmission, check for pen or short circuit to park/neutral position switch and repair,
if required.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Auxiliary Power Outlet: Description and Operation
Fig. 1 Cigar Lighter And Power Outlet
CIGAR LIGHTER OUTLET
A cigar lighter is standard equipment on this model. The cigar lighter is installed in the instrument
panel lower bezel, which is located near the center of the instrument panel, below the radio. The
cigar lighter base is secured by a snap fit within the instrument panel lower bezel.
The cigar lighter knob and heating element unit and the cigar lighter receptacle unit are available
for service. These components cannot be repaired and, if faulty or damaged, they must be
replaced.
The cigar lighter consists of two major components a knob and heating element unit, and the cigar
lighter base or receptacle shell. The receptacle shell is connected to ground, and an insulated
contact ii] the bottom of the shell is connected to battery current. The cigar lighter receives battery
voltage from a fuse in the junction block only when the ignition switch is in the Accessory or ON
positions.
The knob and heating element are encased within a spring-loaded housing, which also features a
sliding protective heat shield. When the knob and heating element are inserted in the receptacle
shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the
cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating
element, and the heating element extends from the housing toward the insulated contact in the
bottom of the receptacle shell.
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the receptacle shell. These clips engage and hold the heating element against the insulated
contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to
heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle
shell, the protective heat shield slides downward on the housing so that the heating element is
recessed and shielded around its circumference for safety.
POWER OUTLET
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel lower bezel, which is located near the center of the instrument panel, below the
radio. The power outlet base is secured by a snap fit within the instrument panel lower bezel. A
plastic protective cap snaps into the power outlet base when the power outlet is not being used,
and hangs from the power outlet base mount by an integral bail strap while the power outlet is in
use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Power Distribution Center (PDC): Description and Operation
POWER DISTRIBUTION
This covers the various standard and optional power distribution components used on this model.
The power distribution system for this vehicle consists of the following components: Power Distribution Center (PDC)
- Junction Block (JB)
- Relay and Fuse Block.
The power distribution system also incorporates various types of circuit control and protection
features, including: Automatic resetting circuit breakers
- Blade-type fuses
- Cartridge fuses
- Circuit splice blocks
- Flashers
- Relays.
Following are general descriptions of the major components in the power distribution system. See
the owner's manual in the vehicle glove box for more information on the features and use of all of
the power distribution system components.
The power distribution system for this vehicle is designed to provide safe, reliable, and centralized
distribution points for the electrical current required to operate all of the many standard and optional
factory-installed electrical and electronic powertrain, chassis, safety, security, comfort and
convenience systems. At the same time, the power distribution system was designed to provide
ready access to these electrical distribution points for the vehicle technician to use when
conducting diagnosis and repair of faulty circuits. The power distribution system can also prove
useful for the sourcing of additional electrical circuits that may be required to provide the electrical
current needed to operate many accessories that the vehicle owner may choose to have installed
in the aftermarket.
Fig. 1 Cigar Lighter And Power Outlet
CIGAR LIGHTER OUTLET
A cigar lighter is standard equipment on this model. The cigar lighter is installed in the instrument
panel lower bezel, which is located near the center of the instrument panel, below the radio. The
cigar lighter base is secured by a snap fit within the instrument panel lower bezel.
The cigar lighter knob and heating element unit and the cigar lighter receptacle unit are available
for service. These components cannot be repaired and, if faulty or damaged, they must be
replaced.
The cigar lighter consists of two major components a knob and heating element unit, and the cigar
lighter base or receptacle shell. The receptacle shell is connected to ground, and an insulated
contact ii] the bottom of the shell is connected to battery current. The cigar lighter receives battery
voltage from a fuse in the junction block only when the ignition switch is in the Accessory or ON
positions.
The knob and heating element are encased within a spring-loaded housing, which also features a
sliding protective heat shield. When the knob and heating element are inserted in the receptacle
shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the
cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating
element, and the heating element extends from the housing toward the insulated contact in the
bottom of the receptacle shell.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Power Distribution Center (PDC)
<--> [Electrical Accessory Panel] > Component Information > Diagrams > Page 4928
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the receptacle shell. These clips engage and hold the heating element against the insulated
contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to
heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle
shell, the protective heat shield slides downward on the housing so that the heating element is
recessed and shielded around its circumference for safety.
CIRCUIT BREAKER
An automatic resetting circuit breaker in the junction block is used to protect the power seat system
circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition
caused by an obstructed or stuck seat adjuster.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.
An automatic resetting circuit breaker in the junction block is used to protect the power window
system circuit. The circuit breaker can protect the system from a short circuit, or from an overload
condition caused by an obstructed or stuck window glass or regulator.
The circuit breaker cannot be repaired and, if faulty, it must be replaced.
Circuit Breaker 1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker
slightly, but be certain that the circuit breaker terminals still
contact the terminals in the junction block cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground. 3. With the voltmeter
positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither
terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as
required.

Fig. 3 Ignition-Off Draw Fuse - Typical
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.
The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Fig. 5 Junction Block Location
JUNCTION BLOCK
An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel
cover (Fig. 5). The JB serves to simplify and centralize numerous electrical components, and to
distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the
need for numerous splice connections and serves in place of a bulkhead connector between many
of the engine compartment, instrument panel, and body wire harnesses. The JB houses up to
nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type
automatic resetting circuit breakers, and two International Standards Organization (ISO) relays
(one standard-type and one micro-type).
The molded plastic JB housing has integral mounting brackets that are secured with two screws to
the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse
access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are
located on the back of the fuse access cover, as well as an adhesive- backed fuse layout map to
ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB
housing is faulty or damaged, the entire JB unit must be replaced.
All of the circuits entering and leaving the JB do so through up to nine wire harness connectors,
which are connected to the JB through integral connector receptacles molded into the JB housing.
Internal connection of all of the JB circuits is accomplished by an intricate combination of hard
wiring and bus bars. Refer to Junction Block for the location of complete JB circuit diagrams.
Fig. 8 Power Distribution Center Location - Typical

Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Power Distribution Center (PDC)
<--> [Electrical Accessory Panel] > Component Information > Diagrams > Page 4931
POWER DISTRIBUTION CENTER
All of the electrical current distributed throughout this vehicle is directed through the standard
equipment Power Distribution Center (PDC) (Fig. 8). The molded plastic PDC housing is located in
the left front corner of the engine compartment, just behind the battery. The PDC houses the
generator cartridge fuse and up to ten maxi-type cartridge fuses, which replace all in-line fusible
links. The PDC also houses up to seven blade-type mini fuses, up to thirteen International
Standards Organization (ISO) relays (one standard-type and twelve micro-type), two joint
connectors (one sixteen-way and one twenty-six-way) and a sixteen-way engine wire harness
in-line connector.
The PDC housing is secured in the engine compartment at three points. Integral mounts on the
front and inboard sides of the PDC housing engage and latch to stanchions that are integral to the
molded plastic battery tray. An integral bracket on the rear of the PDC housing is secured with a
screw to the top of the left front inner wheel house. The PDC housing has a molded plastic cover
that includes two integral latches, one on each side. The PDC cover is easily opened and removed
for service access and has a convenient fuse and relay layout map integral to the inside surface of
the cover to ensure proper component identification.
The PDC unit cannot be repaired and is only serviced as a unit with the headlamp and dash wire
harness. If the internal circuits or the PDC housing are faulty or damaged, the headlamp and dash
wire harness unit must be replaced.
All of the current from the battery and the generator output enters the PDC through one cable with
eyelets that are secured with a nut to the one B(+) terminal stud located just inside the inboard side
of the PDC housing. The PDC cover is unlatched and removed to access the battery and generator
output connection B(+) terminal studs, the fuses, the relays, the joint connectors and the engine
wire harness inline connector. Internal connection of all of the PDC circuits is accomplished by an
intricate combination of hard wiring and bus bars.
POWER OUTLET
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel lower bezel, which is located near the center of the instrument panel, below the
radio. The power outlet base is secured by a snap fit within the instrument panel lower bezel. A
plastic protective cap snaps into the power outlet base when the power outlet is not being used,
and hangs from the power outlet base mount by an integral bail strap while the power outlet is in
use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.
Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).

Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Power Distribution Center (PDC)
<--> [Electrical Accessory Panel] > Component Information > Diagrams > Page 4932
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component
Information > Diagrams > Diagram Information and Instructions > Page 4969
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Starting and Charging > Power and Ground Distribution > Fuse Block > Component
Information > Diagrams > Diagram Information and Instructions > Page 4970
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Fuse Block: Description and Operation
Fig. 5 Junction Block Location
An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel
cover (Fig. 5). The JB serves to simplify and centralize numerous electrical components, and to
distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the
need for numerous splice connections and serves in place of a bulkhead connector between many
of the engine compartment, instrument panel, and body wire harnesses. The JB houses up to
nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type
automatic resetting circuit breakers, and two International Standards Organization (ISO) relays
(one standard-type and one micro-type).
The molded plastic JB housing has integral mounting brackets that are secured with two screws to
the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse
access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are
located on the back of the fuse access cover, as well as an adhesive-backed fuse layout map to
ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB
housing is faulty or damaged, the entire JB unit must be replaced.
All of the circuits entering and leaving the JB do so through up to nine wire harness connectors,
which are connected to the JB through integral connector receptacles molded into the JB housing.
Internal connection of all of the JB circuits is accomplished by an intricate combination of hard
wiring and bus bars. Refer to Junction Block for the location of complete JB circuit diagrams.

Ignition Off-Draw (IOD) Fuse: Description and Operation
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various accessories that require battery current when the
ignition switch is in the OFF position, including the clock. The IOD fuse is removed to prevent
battery discharge during vehicle storage.
When removing or installing the IOD fuse, it is important that the ignition switch be in the OFF
position. Failure to place the ignition switch in the OFF position can cause the radio display to
become scram- bled when the IOD fuse is removed and replaced. Removing and replacing the IOD
fuse again, with the ignition switch in the OFF position, will correct the scrambled display condition.
The IOD fuse should be checked if the radio or clock displays are inoperative. The IOD fuse is
located in the junction block. Refer to the fuse layout label on the back of the instrument panel fuse
access panel for IOD fuse identification and location.
Fig. 3 Ignition-Off Draw Fuse - Typical
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Ignition Off-Draw (IOD) Fuse: Testing and Inspection
Ignition-Off Draw Test The term Ignition-Off Draw (IOD) identifies a normal condition where power
is being drained from the battery with the ignition switch in the OFF position. A normal vehicle
electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the
ignition switch in the OFF position, and all non-ignition controlled circuits in proper working order.
Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control
Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the
vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to
an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the
IOD fuse from the Power Distribution Center (PDC). This will reduce battery discharging.
Excessive IOD can be caused by:
- Electrical items left ON.
- Faulty or improperly adjusted switches.
- Faulty or shorted electronic modules and components.
- An internally shorted generator.
- Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before
replacing a battery. In most cases, the battery can be charged and returned to service after the
excessive IOD condition has been corrected.
Electronic Module Ignition-Off-Draw (IOD) Table
1. Verify that all electrical accessories are OFF. Turn OFF all lamps, remove the ignition key, and
close all doors. If the vehicle is equipped with an
illuminated entry system or an electronically tuned radio, allow the electronic timer function of these
systems to automatically shut off (time out). This may take up to three minutes. See the Electronic
Module Ignition-Off Draw Table for more information.
2. Determine that the underhood lamp is operating properly, then disconnect the lamp wire harness
connector or remove the lamp bulb. 3. Disconnect the battery negative cable. 4. Set an electronic
digital multi-meter to its highest amperage scale. Connect the multi-meter between the
disconnected battery negative cable
terminal clamp and the battery negative terminal post. Make sure that the doors remain closed so
that the illuminated entry system is not activated. The multi-meter amperage reading may remain
high for up to three minutes, or may not give any reading at all while set in the highest amperage
scale, depending upon the electrical equipment in the vehicle. The multi-meter leads must be
securely clamped to the battery negative cable terminal clamp and the battery negative terminal
post. If continuity between the battery negative terminal post and the negative cable terminal clamp
is lost during any part of the IOD test, the electronic timer function will be activated and all of the
tests will have to be repeated.
5. After about three minutes, the high-amperage IOD reading on the multi-meter should become
very low or nonexistent, depending upon the
electrical equipment in the vehicle. If the amperage reading remains high, remove and replace
each fuse or circuit breaker in the Power Distribution Center (PDC) and then in the Junction Block
(JB), one at a time until the amperage reading becomes very low, or nonexistent. This will isolate
each circuit and identify the circuit that is the source of the high-amperage IOD. If the amperage
reading remains high after removing and replacing each fuse and circuit breaker, disconnect the
wire harness from the generator. If the amperage reading now becomes very low or nonexistent,
refer to Charging System for the proper charging system diagnosis and testing procedures. After
the high-amperage IOD has been corrected, switch the multi-meter to progressively lower
amperage scales and, if necessary, repeat the fuse and circuit breaker remove-and-replace
process to identify and correct all sources of excessive IOD. It is now safe to select the lowest
milliampere scale of the multi-meter to check the low- amperage IOD.
CAUTION: Do not open any doors, or turn ON any electrical accessories with the lowest
milliampere scale selected, or the multi-meter may be

damaged.
6. Observe the multi-meter reading. The low-amperage IOD should not exceed thirty-five
milliamperes (0.035 ampere). If the current draw
exceeds thirty-five milliamperes, isolate each circuit using the fuse and circuit breaker
remove-and-replace process in Step 5. The multi-meter reading will drop to within the acceptable
limit when the source of the excessive current draw is disconnected. Repair this circuit as required;
whether a wiring short, incorrect switch adjustment, or a component failure is at fault.

Relay Box: Description and Operation
Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Ignition Off-Draw (IOD) Fuse: Description and Operation
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various accessories that require battery current when the
ignition switch is in the OFF position, including the clock. The IOD fuse is removed to prevent
battery discharge during vehicle storage.
When removing or installing the IOD fuse, it is important that the ignition switch be in the OFF
position. Failure to place the ignition switch in the OFF position can cause the radio display to
become scram- bled when the IOD fuse is removed and replaced. Removing and replacing the IOD
fuse again, with the ignition switch in the OFF position, will correct the scrambled display condition.
The IOD fuse should be checked if the radio or clock displays are inoperative. The IOD fuse is
located in the junction block. Refer to the fuse layout label on the back of the instrument panel fuse
access panel for IOD fuse identification and location.
Fig. 3 Ignition-Off Draw Fuse - Typical
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Ignition Off-Draw (IOD) Fuse: Testing and Inspection
Ignition-Off Draw Test The term Ignition-Off Draw (IOD) identifies a normal condition where power
is being drained from the battery with the ignition switch in the OFF position. A normal vehicle
electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the
ignition switch in the OFF position, and all non-ignition controlled circuits in proper working order.
Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control
Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the
vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to
an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the
IOD fuse from the Power Distribution Center (PDC). This will reduce battery discharging.
Excessive IOD can be caused by:
- Electrical items left ON.
- Faulty or improperly adjusted switches.
- Faulty or shorted electronic modules and components.
- An internally shorted generator.
- Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before
replacing a battery. In most cases, the battery can be charged and returned to service after the
excessive IOD condition has been corrected.
Electronic Module Ignition-Off-Draw (IOD) Table
1. Verify that all electrical accessories are OFF. Turn OFF all lamps, remove the ignition key, and
close all doors. If the vehicle is equipped with an
illuminated entry system or an electronically tuned radio, allow the electronic timer function of these
systems to automatically shut off (time out). This may take up to three minutes. See the Electronic
Module Ignition-Off Draw Table for more information.
2. Determine that the underhood lamp is operating properly, then disconnect the lamp wire harness
connector or remove the lamp bulb. 3. Disconnect the battery negative cable. 4. Set an electronic
digital multi-meter to its highest amperage scale. Connect the multi-meter between the
disconnected battery negative cable
terminal clamp and the battery negative terminal post. Make sure that the doors remain closed so
that the illuminated entry system is not activated. The multi-meter amperage reading may remain
high for up to three minutes, or may not give any reading at all while set in the highest amperage
scale, depending upon the electrical equipment in the vehicle. The multi-meter leads must be
securely clamped to the battery negative cable terminal clamp and the battery negative terminal
post. If continuity between the battery negative terminal post and the negative cable terminal clamp
is lost during any part of the IOD test, the electronic timer function will be activated and all of the
tests will have to be repeated.
5. After about three minutes, the high-amperage IOD reading on the multi-meter should become
very low or nonexistent, depending upon the
electrical equipment in the vehicle. If the amperage reading remains high, remove and replace
each fuse or circuit breaker in the Power Distribution Center (PDC) and then in the Junction Block
(JB), one at a time until the amperage reading becomes very low, or nonexistent. This will isolate
each circuit and identify the circuit that is the source of the high-amperage IOD. If the amperage
reading remains high after removing and replacing each fuse and circuit breaker, disconnect the
wire harness from the generator. If the amperage reading now becomes very low or nonexistent,
refer to Charging System for the proper charging system diagnosis and testing procedures. After
the high-amperage IOD has been corrected, switch the multi-meter to progressively lower
amperage scales and, if necessary, repeat the fuse and circuit breaker remove-and-replace
process to identify and correct all sources of excessive IOD. It is now safe to select the lowest
milliampere scale of the multi-meter to check the low- amperage IOD.
CAUTION: Do not open any doors, or turn ON any electrical accessories with the lowest
milliampere scale selected, or the multi-meter may be

damaged.
6. Observe the multi-meter reading. The low-amperage IOD should not exceed thirty-five
milliamperes (0.035 ampere). If the current draw
exceeds thirty-five milliamperes, isolate each circuit using the fuse and circuit breaker
remove-and-replace process in Step 5. The multi-meter reading will drop to within the acceptable
limit when the source of the excessive current draw is disconnected. Repair this circuit as required;
whether a wiring short, incorrect switch adjustment, or a component failure is at fault.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Power and Ground Distribution > Auxiliary Power Outlet > Component Information > Diagrams
> Diagram Information and Instructions > Page 5189
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

voltage from a fuse in the junction block only when the ignition switch is in the Accessory or ON
positions.
The knob and heating element are encased within a spring-loaded housing, which also features a
sliding protective heat shield. When the knob and heating element are inserted in the receptacle
shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the
cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating
element, and the heating element extends from the housing toward the insulated contact in the
bottom of the receptacle shell.
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the receptacle shell. These clips engage and hold the heating element against the insulated
contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to
heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle
shell, the protective heat shield slides downward on the housing so that the heating element is
recessed and shielded around its circumference for safety.
POWER OUTLET
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel lower bezel, which is located near the center of the instrument panel, below the
radio. The power outlet base is secured by a snap fit within the instrument panel lower bezel. A
plastic protective cap snaps into the power outlet base when the power outlet is not being used,
and hangs from the power outlet base mount by an integral bail strap while the power outlet is in
use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Power Distribution Center (PDC): Description and Operation
POWER DISTRIBUTION
This covers the various standard and optional power distribution components used on this model.
The power distribution system for this vehicle consists of the following components: Power Distribution Center (PDC)
- Junction Block (JB)
- Relay and Fuse Block.
The power distribution system also incorporates various types of circuit control and protection
features, including: Automatic resetting circuit breakers
- Blade-type fuses
- Cartridge fuses
- Circuit splice blocks
- Flashers
- Relays.
Following are general descriptions of the major components in the power distribution system. See
the owner's manual in the vehicle glove box for more information on the features and use of all of
the power distribution system components.
The power distribution system for this vehicle is designed to provide safe, reliable, and centralized
distribution points for the electrical current required to operate all of the many standard and optional
factory-installed electrical and electronic powertrain, chassis, safety, security, comfort and
convenience systems. At the same time, the power distribution system was designed to provide
ready access to these electrical distribution points for the vehicle technician to use when
conducting diagnosis and repair of faulty circuits. The power distribution system can also prove
useful for the sourcing of additional electrical circuits that may be required to provide the electrical
current needed to operate many accessories that the vehicle owner may choose to have installed
in the aftermarket.
Fig. 1 Cigar Lighter And Power Outlet
CIGAR LIGHTER OUTLET
A cigar lighter is standard equipment on this model. The cigar lighter is installed in the instrument
panel lower bezel, which is located near the center of the instrument panel, below the radio. The
cigar lighter base is secured by a snap fit within the instrument panel lower bezel.
The cigar lighter knob and heating element unit and the cigar lighter receptacle unit are available
for service. These components cannot be repaired and, if faulty or damaged, they must be
replaced.
The cigar lighter consists of two major components a knob and heating element unit, and the cigar
lighter base or receptacle shell. The receptacle shell is connected to ground, and an insulated
contact ii] the bottom of the shell is connected to battery current. The cigar lighter receives battery
voltage from a fuse in the junction block only when the ignition switch is in the Accessory or ON
positions.
The knob and heating element are encased within a spring-loaded housing, which also features a
sliding protective heat shield. When the knob and heating element are inserted in the receptacle
shell, the heating element resistor coil is grounded through its housing to the receptacle shell. If the
cigar lighter knob is pushed inward, the heat shield slides up toward the knob exposing the heating
element, and the heating element extends from the housing toward the insulated contact in the
bottom of the receptacle shell.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Power and Ground Distribution > Power Distribution Center (PDC) <--> [Electrical Accessory
Panel] > Component Information > Diagrams > Page 5262
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom
of the receptacle shell. These clips engage and hold the heating element against the insulated
contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to
heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element
causing the spring-clips to expand. Once the spring-clips expand far enough to release the heating
element, the spring-loaded housing forces the knob and heating element to pop back outward to
their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle
shell, the protective heat shield slides downward on the housing so that the heating element is
recessed and shielded around its circumference for safety.
CIRCUIT BREAKER
An automatic resetting circuit breaker in the junction block is used to protect the power seat system
circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition
caused by an obstructed or stuck seat adjuster.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.
An automatic resetting circuit breaker in the junction block is used to protect the power window
system circuit. The circuit breaker can protect the system from a short circuit, or from an overload
condition caused by an obstructed or stuck window glass or regulator.
The circuit breaker cannot be repaired and, if faulty, it must be replaced.
Circuit Breaker 1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker
slightly, but be certain that the circuit breaker terminals still
contact the terminals in the junction block cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground. 3. With the voltmeter
positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither
terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as
required.

Fig. 3 Ignition-Off Draw Fuse - Typical
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.
The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Fig. 5 Junction Block Location
JUNCTION BLOCK
An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel
cover (Fig. 5). The JB serves to simplify and centralize numerous electrical components, and to
distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the
need for numerous splice connections and serves in place of a bulkhead connector between many
of the engine compartment, instrument panel, and body wire harnesses. The JB houses up to
nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type
automatic resetting circuit breakers, and two International Standards Organization (ISO) relays
(one standard-type and one micro-type).
The molded plastic JB housing has integral mounting brackets that are secured with two screws to
the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse
access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are
located on the back of the fuse access cover, as well as an adhesive- backed fuse layout map to
ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB
housing is faulty or damaged, the entire JB unit must be replaced.
All of the circuits entering and leaving the JB do so through up to nine wire harness connectors,
which are connected to the JB through integral connector receptacles molded into the JB housing.
Internal connection of all of the JB circuits is accomplished by an intricate combination of hard
wiring and bus bars. Refer to Junction Block for the location of complete JB circuit diagrams.
Fig. 8 Power Distribution Center Location - Typical
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Power and Ground Distribution > Power Distribution Center (PDC) <--> [Electrical Accessory
Panel] > Component Information > Diagrams > Page 5265
POWER DISTRIBUTION CENTER
All of the electrical current distributed throughout this vehicle is directed through the standard
equipment Power Distribution Center (PDC) (Fig. 8). The molded plastic PDC housing is located in
the left front corner of the engine compartment, just behind the battery. The PDC houses the
generator cartridge fuse and up to ten maxi-type cartridge fuses, which replace all in-line fusible
links. The PDC also houses up to seven blade-type mini fuses, up to thirteen International
Standards Organization (ISO) relays (one standard-type and twelve micro-type), two joint
connectors (one sixteen-way and one twenty-six-way) and a sixteen-way engine wire harness
in-line connector.
The PDC housing is secured in the engine compartment at three points. Integral mounts on the
front and inboard sides of the PDC housing engage and latch to stanchions that are integral to the
molded plastic battery tray. An integral bracket on the rear of the PDC housing is secured with a
screw to the top of the left front inner wheel house. The PDC housing has a molded plastic cover
that includes two integral latches, one on each side. The PDC cover is easily opened and removed
for service access and has a convenient fuse and relay layout map integral to the inside surface of
the cover to ensure proper component identification.
The PDC unit cannot be repaired and is only serviced as a unit with the headlamp and dash wire
harness. If the internal circuits or the PDC housing are faulty or damaged, the headlamp and dash
wire harness unit must be replaced.
All of the current from the battery and the generator output enters the PDC through one cable with
eyelets that are secured with a nut to the one B(+) terminal stud located just inside the inboard side
of the PDC housing. The PDC cover is unlatched and removed to access the battery and generator
output connection B(+) terminal studs, the fuses, the relays, the joint connectors and the engine
wire harness inline connector. Internal connection of all of the PDC circuits is accomplished by an
intricate combination of hard wiring and bus bars.
POWER OUTLET
An accessory power outlet is optional equipment on this model. The power outlet is installed in the
instrument panel lower bezel, which is located near the center of the instrument panel, below the
radio. The power outlet base is secured by a snap fit within the instrument panel lower bezel. A
plastic protective cap snaps into the power outlet base when the power outlet is not being used,
and hangs from the power outlet base mount by an integral bail strap while the power outlet is in
use.
The power outlet receptacle unit and the accessory power outlet protective cap are available for
service. The power outlet receptacle cannot be repaired and, if faulty or damaged, it must be
replaced.
The power outlet base or receptacle shell is connected to ground, and an insulated contact in the
bottom of the shell is connected to battery current. The power outlet receives battery voltage from a
fuse in the Power Distribution Center (PDC) at all times.
While the power outlet is very similar to a cigar lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the receptacle shell that are used to secure the cigar
lighter heating element to the insulated contact.
Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Power and Ground Distribution > Power Distribution Center (PDC) <--> [Electrical Accessory
Panel] > Component Information > Diagrams > Page 5266
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

Information and Instructions > Page 5303
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Power and Ground Distribution > Fuse Block > Component Information > Diagrams > Diagram
Information and Instructions > Page 5304
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Fuse Block: Description and Operation
Fig. 5 Junction Block Location
An electrical Junction Block (JB) is concealed behind the left outboard end of the instrument panel
cover (Fig. 5). The JB serves to simplify and centralize numerous electrical components, and to
distribute electrical current to many of the accessory systems in the vehicle. It also eliminates the
need for numerous splice connections and serves in place of a bulkhead connector between many
of the engine compartment, instrument panel, and body wire harnesses. The JB houses up to
nineteen blade-type fuses (two standard-type and seventeen mini-type), up to two blade- type
automatic resetting circuit breakers, and two International Standards Organization (ISO) relays
(one standard-type and one micro-type).
The molded plastic JB housing has integral mounting brackets that are secured with two screws to
the left instrument panel end bracket. The left end of the instrument panel cover has a snap-fit fuse
access panel that can be removed for service of the JB. A fuse puller and spare fuse holders are
located on the back of the fuse access cover, as well as an adhesive-backed fuse layout map to
ensure proper fuse identification.
The JB unit cannot be repaired and is only serviced as an assembly. If any internal circuit or the JB
housing is faulty or damaged, the entire JB unit must be replaced.
All of the circuits entering and leaving the JB do so through up to nine wire harness connectors,
which are connected to the JB through integral connector receptacles molded into the JB housing.
Internal connection of all of the JB circuits is accomplished by an intricate combination of hard
wiring and bus bars. Refer to Junction Block for the location of complete JB circuit diagrams.

Ignition Off-Draw (IOD) Fuse: Description and Operation
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various accessories that require battery current when the
ignition switch is in the OFF position, including the clock. The IOD fuse is removed to prevent
battery discharge during vehicle storage.
When removing or installing the IOD fuse, it is important that the ignition switch be in the OFF
position. Failure to place the ignition switch in the OFF position can cause the radio display to
become scram- bled when the IOD fuse is removed and replaced. Removing and replacing the IOD
fuse again, with the ignition switch in the OFF position, will correct the scrambled display condition.
The IOD fuse should be checked if the radio or clock displays are inoperative. The IOD fuse is
located in the junction block. Refer to the fuse layout label on the back of the instrument panel fuse
access panel for IOD fuse identification and location.

IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Ignition Off-Draw (IOD) Fuse: Testing and Inspection
Ignition-Off Draw Test The term Ignition-Off Draw (IOD) identifies a normal condition where power
is being drained from the battery with the ignition switch in the OFF position. A normal vehicle
electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the
ignition switch in the OFF position, and all non-ignition controlled circuits in proper working order.
Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control
Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the
vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to
an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the
IOD fuse from the Power Distribution Center (PDC). This will reduce battery discharging.
Excessive IOD can be caused by:
- Electrical items left ON.
- Faulty or improperly adjusted switches.
- Faulty or shorted electronic modules and components.
- An internally shorted generator.
- Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before
replacing a battery. In most cases, the battery can be charged and returned to service after the
excessive IOD condition has been corrected.
Electronic Module Ignition-Off-Draw (IOD) Table
1. Verify that all electrical accessories are OFF. Turn OFF all lamps, remove the ignition key, and
close all doors. If the vehicle is equipped with an
illuminated entry system or an electronically tuned radio, allow the electronic timer function of these
systems to automatically shut off (time out). This may take up to three minutes. See the Electronic
Module Ignition-Off Draw Table for more information.
2. Determine that the underhood lamp is operating properly, then disconnect the lamp wire harness
connector or remove the lamp bulb. 3. Disconnect the battery negative cable. 4. Set an electronic
digital multi-meter to its highest amperage scale. Connect the multi-meter between the
disconnected battery negative cable
terminal clamp and the battery negative terminal post. Make sure that the doors remain closed so
that the illuminated entry system is not activated. The multi-meter amperage reading may remain
high for up to three minutes, or may not give any reading at all while set in the highest amperage
scale, depending upon the electrical equipment in the vehicle. The multi-meter leads must be
securely clamped to the battery negative cable terminal clamp and the battery negative terminal
post. If continuity between the battery negative terminal post and the negative cable terminal clamp
is lost during any part of the IOD test, the electronic timer function will be activated and all of the
tests will have to be repeated.
5. After about three minutes, the high-amperage IOD reading on the multi-meter should become
very low or nonexistent, depending upon the
electrical equipment in the vehicle. If the amperage reading remains high, remove and replace
each fuse or circuit breaker in the Power Distribution Center (PDC) and then in the Junction Block
(JB), one at a time until the amperage reading becomes very low, or nonexistent. This will isolate
each circuit and identify the circuit that is the source of the high-amperage IOD. If the amperage
reading remains high after removing and replacing each fuse and circuit breaker, disconnect the
wire harness from the generator. If the amperage reading now becomes very low or nonexistent,
refer to Charging System for the proper charging system diagnosis and testing procedures. After
the high-amperage IOD has been corrected, switch the multi-meter to progressively lower
amperage scales and, if necessary, repeat the fuse and circuit breaker remove-and-replace
process to identify and correct all sources of excessive IOD. It is now safe to select the lowest
milliampere scale of the multi-meter to check the low- amperage IOD.
CAUTION: Do not open any doors, or turn ON any electrical accessories with the lowest
milliampere scale selected, or the multi-meter may be

damaged.
6. Observe the multi-meter reading. The low-amperage IOD should not exceed thirty-five
milliamperes (0.035 ampere). If the current draw
exceeds thirty-five milliamperes, isolate each circuit using the fuse and circuit breaker
remove-and-replace process in Step 5. The multi-meter reading will drop to within the acceptable
limit when the source of the excessive current draw is disconnected. Repair this circuit as required;
whether a wiring short, incorrect switch adjustment, or a component failure is at fault.

Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Fig. 10 Relay And Fuse Block Location
RELAY CENTER
The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block
(JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 10). The
relay and fuse block provides additional capacity for distribution and control of electrical current for
some of the accessory systems that are unique to this vehicle, and which could not be
accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has
cavities for up to four additional blade4ype mini fuses, the electronic combination flasher, and three
additional International Standards Organization relays (one standard-type and two micro-type).
The relay and fuse block components are accessed for service by removing the steering column
opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB
mounting tabs and pulled out from under the instrument panel. Service replacement of the relay
and fuse block unit requires instrument panel assembly removal.
The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument
panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or
damaged, the entire instrument panel wire harness unit must be replaced.
The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or
leaving this module do so through the instrument panel wire harness. Internal connection of all of
the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block for the
location of complete circuit diagrams and cavity assignments for the relay and fuse block.

Ignition Off-Draw (IOD) Fuse: Description and Operation
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various accessories that require battery current when the
ignition switch is in the OFF position, including the clock. The IOD fuse is removed to prevent
battery discharge during vehicle storage.
When removing or installing the IOD fuse, it is important that the ignition switch be in the OFF
position. Failure to place the ignition switch in the OFF position can cause the radio display to
become scram- bled when the IOD fuse is removed and replaced. Removing and replacing the IOD
fuse again, with the ignition switch in the OFF position, will correct the scrambled display condition.
The IOD fuse should be checked if the radio or clock displays are inoperative. The IOD fuse is
located in the junction block. Refer to the fuse layout label on the back of the instrument panel fuse
access panel for IOD fuse identification and location.
Fig. 3 Ignition-Off Draw Fuse - Typical
IOD FUSE
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse (Fig. 3) that is disconnected within
the Junction Block (JB) when the vehicle is shipped from the factory. Dealer personnel are to
reconnect the IOD fuse in the JB as part of the preparation procedures performed just prior to new
vehicle delivery.
The left end of the instrument panel cover has a snap-fit fuse access panel that can be removed to
provide service access to the fuses in the JB. A finger recess is molded into the access panel for
easy removal. An adhesive-backed fuse layout map is secured to the instrument panel side of the
access panel to ensure proper fuse identification. The IOD fuse is a 15 ampere mini blade-type
fuse. The fuse is secured within a black molded plastic fuse holder and puller unit that serves both
as a tool for disconnecting and reconnecting the fuse in its JB cavity, and as a fuse holder that
conveniently stores the fuse in the same JB cavity after it has been disconnected.
The term ignition-off draw identifies a normal condition where power is being drained from the
battery with the ignition switch in the OFF position. The IOD fuse feeds the memory and sleep
mode functions for some of the electronic modules in the vehicle as well as various other
accessories that require battery current when the ignition switch is in the OFF position, including
the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle
electrical system during new vehicle transportation and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation company and dealer personnel.
The IOD fuse is disconnected from JB fuse cavity 12 when the vehicle is shipped from the
assembly plant. Dealer personnel must reconnect the IOD fuse when the vehicle is being prepared
for delivery in order to restore full electrical system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes transparent and the fuse that has been assigned
the IOD designation becomes only another Fused B(+) circuit fuse. The IOD fuse serves no useful
purpose to the dealer technician in the service or diagnosis of any vehicle system or condition,
other than the same purpose as that of any other standard circuit protection device.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery
depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it
must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this
normal condition. If a vehicle will be stored for more than about thirty days, the battery negative
cable should be disconnected to eliminate normal IOD; and, the battery should be tested and
recharged at regular intervals during the vehicle storage period to prevent the battery from
becoming discharged or damaged. Refer to Battery for the location of additional service information
covering the battery.

Ignition Off-Draw (IOD) Fuse: Testing and Inspection
Ignition-Off Draw Test The term Ignition-Off Draw (IOD) identifies a normal condition where power
is being drained from the battery with the ignition switch in the OFF position. A normal vehicle
electrical system will draw from five to thirty-five milliamperes (0.005 to 0.035 ampere) with the
ignition switch in the OFF position, and all non-ignition controlled circuits in proper working order.
Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control
Module (PCM), digital clock, electronically tuned radio, and other modules which may vary with the
vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to
an inadequate level. When a vehicle will not be used for twenty days or more (stored), remove the
IOD fuse from the Power Distribution Center (PDC). This will reduce battery discharging.
Excessive IOD can be caused by:
- Electrical items left ON.
- Faulty or improperly adjusted switches.
- Faulty or shorted electronic modules and components.
- An internally shorted generator.
- Intermittent shorts in the wiring.
If the IOD is over thirty-five milliamperes, the problem must be found and corrected before
replacing a battery. In most cases, the battery can be charged and returned to service after the
excessive IOD condition has been corrected.
Electronic Module Ignition-Off-Draw (IOD) Table
1. Verify that all electrical accessories are OFF. Turn OFF all lamps, remove the ignition key, and
close all doors. If the vehicle is equipped with an
illuminated entry system or an electronically tuned radio, allow the electronic timer function of these
systems to automatically shut off (time out). This may take up to three minutes. See the Electronic
Module Ignition-Off Draw Table for more information.
2. Determine that the underhood lamp is operating properly, then disconnect the lamp wire harness
connector or remove the lamp bulb. 3. Disconnect the battery negative cable. 4. Set an electronic
digital multi-meter to its highest amperage scale. Connect the multi-meter between the
disconnected battery negative cable
terminal clamp and the battery negative terminal post. Make sure that the doors remain closed so
that the illuminated entry system is not activated. The multi-meter amperage reading may remain
high for up to three minutes, or may not give any reading at all while set in the highest amperage
scale, depending upon the electrical equipment in the vehicle. The multi-meter leads must be
securely clamped to the battery negative cable terminal clamp and the battery negative terminal
post. If continuity between the battery negative terminal post and the negative cable terminal clamp
is lost during any part of the IOD test, the electronic timer function will be activated and all of the
tests will have to be repeated.
5. After about three minutes, the high-amperage IOD reading on the multi-meter should become
very low or nonexistent, depending upon the
electrical equipment in the vehicle. If the amperage reading remains high, remove and replace
each fuse or circuit breaker in the Power Distribution Center (PDC) and then in the Junction Block
(JB), one at a time until the amperage reading becomes very low, or nonexistent. This will isolate
each circuit and identify the circuit that is the source of the high-amperage IOD. If the amperage
reading remains high after removing and replacing each fuse and circuit breaker, disconnect the
wire harness from the generator. If the amperage reading now becomes very low or nonexistent,
refer to Charging System for the proper charging system diagnosis and testing procedures. After
the high-amperage IOD has been corrected, switch the multi-meter to progressively lower
amperage scales and, if necessary, repeat the fuse and circuit breaker remove-and-replace
process to identify and correct all sources of excessive IOD. It is now safe to select the lowest
milliampere scale of the multi-meter to check the low- amperage IOD.
CAUTION: Do not open any doors, or turn ON any electrical accessories with the lowest
milliampere scale selected, or the multi-meter may be

damaged.
6. Observe the multi-meter reading. The low-amperage IOD should not exceed thirty-five
milliamperes (0.035 ampere). If the current draw
exceeds thirty-five milliamperes, isolate each circuit using the fuse and circuit breaker
remove-and-replace process in Step 5. The multi-meter reading will drop to within the acceptable
limit when the source of the excessive current draw is disconnected. Repair this circuit as required;
whether a wiring short, incorrect switch adjustment, or a component failure is at fault.

Alignment: Description and Operation
DESCRIPTION
Wheel alignment involves the correct positioning of the wheels in relation to the vehicle. The
positioning is accomplished through suspension and steering linkage adjustments. An alignment is
considered essential for efficient steering, good directional stability and to minimize tire wear. The
most important measurements of an alignment are caster, camber and toe.
CAUTION: Never attempt to modify suspension or steering components by heating or bending.
NOTE: Periodic lubrication of the front suspension/steering system components may be required.
Rubber bushings must never be lubricated.
OPERATION
- CASTER is the forward or rearward tilt of the steering knuckle from vertical. Tilting the top of the
knuckle forward provides negative caster. Tilting the top of the knuckle rearward provides positive
caster. Positive caster promotes directional stability. This angle enables the front wheels to return
to a straight ahead position after turns.
- CAMBER is the inward or outward tilt of the wheel relative to the center of the vehicle. Tilting the
top of the wheel inward provides negative camber. Tilting the top of the wheel outward provides
positive camber. Incorrect camber will cause wear on the inside or outside edge of the tire.
- TOE is the difference between the leading inside edges and trailing inside edges of the front tires.
wheel position out of specification cause's unstable steering, uneven tire wear and steering wheel
off center. The wheel toe position is the final front wheel alignment adjustment.
- THRUST ANGLE is the angle of the rear axle relative to the centerline of the vehicle. Incorrect
thrust angle can cause off-center steering and excessive tire wear. This angle is not adjustable,
damaged component(s) must be replaced to correct the thrust angle.

Alignment: Service and Repair Pre-Alignment Inspection
DIAGNOSIS AND TESTING - PRE-ALIGNMENT INSPECTION
Before starting wheel alignment, the following inspection and necessary corrections must be
completed. 1. Inspect tires for size, air pressure and tread wear. 2. Inspect front wheel bearings for
wear. 3. Inspect front wheels for excessive radial or lateral runout and balance. 4. Inspect ball
studs, linkage pivot points and steering gear for looseness, roughness or binding. 5. Inspect
suspension components for wear and noise. 6. On 4x4 vehicles check suspension height. 7. Road
test the vehicle.

Alignment: Service and Repair Wheel Alignment
STANDARD PROCEDURE - HEIGHT MEASUREMENT
The vehicle suspension height should be measured and adjusted if necessary before performing
wheel alignment procedure. Also when front suspension components have been replaced. This
measure must be performed with the vehicle supporting it's own weight and taken on both sides of
the vehicle. 1. Jounce the front of the vehicle.
2. Measure and record the distance between the ground and the center of the lower suspension
arm rear mounting bolt head. 3. Measure and record the distance between the ground and the
center of the front wheel. 4. Subtract the first measurement from the second measurement. The
difference between the two measurement should be 73 mm (2.9 inches) + 3
mm (0.12 inches).
STANDARD PROCEDURE- HEIGHT ADJUSTMENT
The vehicle suspension height should be measured and adjusted if necessary before performing
wheel alignment procedure. Also when front suspension components have been replaced. This
measure must be performed with the vehicle supporting it's own weight and taken on both sides of
the vehicle. To adjust the vehicle height turn the torsion bar adjustment bolt CLOCKWISE to raise
the vehicle and COUNTER CLOCKWISE to lower the vehicle.
CAUTION: ALWAYS raise the vehicle to the correct suspension height, NEVER lower the vehicle
to obtain the correct suspension height. If the vehicle suspension height is too high, lower the
vehicle below the height specification. Then raise the vehicle to the correct suspension height
specification. This will insure the vehicle maintains the proper suspension height.
NOTE: If a height adjustment has been made, perform height measurement again on both sides of
the vehicle.
STANDARD PROCEDURE - CAMBER AND CASTER ADJUSTMENT
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Steering and Suspension > Alignment > System Information > Service and Repair >
Pre-Alignment Inspection > Page 5524
Camber and caster angle adjustments involve changing the position of the upper suspension arm
pivot bar.
NOTE: On 4x2 vehicles use Alignment Tool 8393 for alignment. The tool attaches to the pivot bar
on the upper control arm.
STANDARD PROCEDURE- CASTER
Moving the rear position of the pivot bar in or out, will change the caster angle significantly and
camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of
the pivot bar in or out. Then move the front of the pivot bar slightly in the opposite direction. To
increase positive caster angle, move the rear position of the pivot bar inward (toward the engine).
Move the front of pivot bar outward (away from the engine) slightly until the original camber angle is
obtained.
STANDARD PROCEDURE - CAMBER
Move the front of the pivot bar in or out. This will change the camber angle significantly and caster
angle slightly. After adjustment is made tighten the pivot bar nuts to proper torque specification.
STANDARD PROCEDURE - TOE ADJUSTMENT
The wheel toe position adjustment is the final adjustment. 1. Start the engine and turn wheels both
ways before straightening the wheels. Secure the steering wheel with the front wheels in the
straight-ahead
position.
2. Loosen the tie rod jam nuts.
NOTE: Each front wheel should be adjusted for one-half of the total toe position specification. This
will ensure the steering wheel will be centered when the wheels are positioned straight-ahead.
3. Adjust the wheel toe position by turning the tie rod as necessary. 4. Tighten the tie rod jam nut to
75 Nm (55 ft. lbs.).

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

DISCUSSION:
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4
(MS9602) and it provides superior performance at both low and high temperatures. WJ/WG and ZH
vehicles use unique power steering fluids. Refer to the table to identify factory fill and the approved
service power steering fluid by year and model. Note that MS9602 is Red in color and MS5931 and
MS9933 are Amber/Yellow in color. All three fluids will darken in color with usage and fluid color is
no longer an indication of fluid condition.
The part numbers for MS9602 are 05013457AA (quart) and 05013458AA (gallon). The part number
for MS5931 is 04883077 (quart). The part number for MB345 is 05127381AA.
MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931. On
some past models, MS9602 should be used as the replacement fluid. On these models, if a power
steering system is being serviced that results in a large fluid loss, such as a pump, hose or
gear/rack replacement, the complete system should be drained and filled with MS9602.

Power Steering Pressure Switch: Description and Operation
DESCRIPTION
A pressure sensing switch is included in the power steering system (mounted on the high pressure
line). This switch will be used only on vehicles equipped with a 4.7L V-8 engine and power
steering.
OPERATION
The power steering pressure switch provides an input to the Powertrain Control Module (PCM).
This input is provided during periods of high pump load and low engine rpm; such as during parking
maneuvers. The PCM will then increase the idle speed through the Idle Air Control (IAC) motor.
This is done to prevent the engine from stalling under the increased load.
When steering pump pressure exceeds 3275 kPa ± 690 kPa (475 psi ± 100 psi), the normally
closed switch will open and the PCM will increase the engine idle speed. This will prevent the
engine from stalling.
When pump pressure drops to approximately 1379 kPa (200 psi), the switch circuit will re-close
and engine idle speed will return to its previous setting.

DISCUSSION: The fasteners that retain the transmission crossmember to the frame utilize a thread
lock patch on the threads of the fastener. The thread lock patch is required to help prevent the
fastener from loosening during normal vehicle usage. When the transmission crossmember is
required to be removed during service, the amount of thread patch material on the fastener will
deteriorate during fastener removal. To ensure that the fastener retention is not compromised after
service, the transmission crossmember fastener threads must have Mopar Lock & Seal p/n
04318031 added to the threads of each fastener.

Suspension Strut / Shock Absorber: Testing and Inspection Front
DIAGNOSIS AND TESTING - SHOCK ABSORBERS
A knocking or rattling noise from a shock absorber may be caused by movement between
mounting bushings and metal brackets or attaching components. These noises can usually be
stopped by tightening the attaching nuts. If the noise persists, inspect for damaged and worn
bushings, and attaching components. Repair as necessary if any of these conditions exist.
A squeaking noise from the shock absorber may be caused by the hydraulic valving and may be
intermittent. This condition is not repairable and the shock absorber must be replaced.
The shock absorbers are not refillable or adjustable. If a malfunction occurs, the shock absorber
must be replaced. 1b test a shock absorber, hold it in an upright position and force the piston in
and out of the cylinder four or five times. The action throughout each stroke should be smooth and
even.
The shock absorber bushings do not require any type of lubrication. Do not attempt to stop bushing
noise by lubricating them. Grease and mineral oil base lubricants will deteriorate the bushing.

Description and Operation
Wheels: Description and Operation
DESCRIPTION
The rim size is on the vehicle safety certification label located on the drivers door shut face. The
size of the rim is determined by the drivetrain package. Original equipment wheels/rims are
designed for operation up to the specified maximum vehicle capacity.
Fig. 1
All models use stamped steel, cast aluminum or forged aluminum wheels. Every wheel has raised
sections between the rim flanges and rim drop well called safety humps.
Initial inflation of the tire forces the bead over these raised sections. In case of rapid loss of air
pressure, the raised sections help hold the tire on the wheel.
The wheel studs and nuts are designed for specific applications. All aluminum and some steel
wheels have wheel stud nuts with an enlarged nose. This enlarged nose is necessary to ensure
proper retention of the wheels. Do not use replacement studs or nuts with a different design or
lesser quality.

Air Door Actuator / Motor: Description and Operation Blend Door Actuator
BLEND DOOR ACTUATOR - FRONT
The blend door actuators are reversible, 12-volt Direct Current (DC), servo motors. Models with the
single zone heater and air conditioner system have a single blend air door, which is controlled by a
single blend door actuator. Models with the optional dual zone front heater and air conditioner
system have dual blend air doors, which are controlled by two blend door actuators. The single
zone blend door actuator is located on the driver side end of the heater-A/C housing unit, close to
the dash panel. In the dual zone system, the same blend door actuator used for the single zone
system becomes the passenger blend door actuator, and is mechanically connected to only the
passenger side blend air door. In the dual zone system, a second separate blend door actuator is
also located on the driver side end of the heater-A/C housing unit close to the instrument panel,
and is mechanically connected to only the driver side blend air door.
The blend door actuators are interchangeable with each other, as well as with the actuators for the
mode door and the recirculation air door. Each actuator is contained within an identical black
molded plastic housing with an integral wire connector receptacle. Two integral mounting tabs
allow the actuator to be secured with two screws to the heater-A/C unit housing. Each actuator also
has an identical output shaft with splines that connects it to the link-age that drives the proper blend
air door. The blend door actuators do not require mechanical indexing to the blend door linkage, as
they are electronically calibrated by the heater-A/C control module. The blend door actuators
cannot be adjusted or repaired and, if damaged or faulty, they must be replaced.
Each blend door actuator is connected to the heater-A/C control module through the vehicle
electrical system by a dedicated two-wire take out and connector of the HAVC wire harness. The
blend door actuator can move the blend air door in two directions. When the heater-A/C control
module pulls the voltage on one side of the motor connection high and the other connection low,
the blend air door will move in one direction. When the module reverses the polarity of the voltage
to the motor, the blend air door moves in the opposite direction. When the module makes the
voltage to both connections high or both connections low, the blend air door stops and will not
move. These same motor connections also provide a feedback signal to the heater-A/C control
module. This feedback signal allows the module to monitor the operation and relative positions of
the blend door actuator and the blend air door. The heater-A/C control module learns the blend air
door stop positions during the calibration procedure and will store a Diagnostic Trouble Code
(DTC) for any problems it detects in the blend door actuator circuits. The blend door actuator can
be diagnosed using a DRB III scan tool. Refer to the appropriate diagnostic information.

Air Door Actuator / Motor: Description and Operation Fresh Air/Recirculation Actuator
RECIRCULATION DOOR ACTUATOR - FRONT
The recirculation door actuator is a reversible, 12-volt Direct Current (DC), servo motor. The single
recirculation door actuator is located on the passenger side end of the heater-A/C housing unit, on
the bottom of the lower intake air housing. The recirculation door actuator is mechanically
connected to the recirculation air door. The recirculation door actuator is interchangeable with the
actuators for the blend air door(s) and the mode door. Each actuator is contained within an
identical black molded plastic housing with an integral wire connector receptacle. Two integral
mounting tabs allow the actuator to be secured with two screws to the lower intake air housing.
Each actuator also has an identical output shaft with splines that connects it to the linkage that
drives the recirculation air door. The recirculation door actuator does not require mechanical
indexing to the recirculation air door; as it is electronically calibrated by the heater-A/C control
module. The recirculation door actuator cannot be adjusted or repaired and, if damaged or faulty, it
must be replaced.
The recirculation door actuator is connected to the heater-A/C control module through the vehicle
electrical system by a dedicated two-wire take out and connector of the HVAC wire harness. The
recirculation door actuator can move the recirculation door in two directions. When the heater-A/C
control module pulls the voltage on one side of the motor connection high and the other connection
low, the recirculation air door will move in one direction. When the module reverses the polarity of
the voltage to the motor; the recirculation air door moves in the opposite direction. When the
module makes the voltage to both connections high or both connections low, the recirculation air
door stops and will not move. These same motor connections also provide a feedback signal to the
heater-A/C control module. This feedback signal allows the module to monitor the operation and
relative position of the recirculation door actuator and the recirculation air door. The heater-A/C
control module learns the recirculation air door stop positions during the calibration procedure and
will store a Diagnostic Trouble Code (DTC) for any problems it detects in the recirculation door
actuator circuits. The recirculation door actuator can be diagnosed using a DRB III scan tool. Refer
to the appropriate diagnostic information.

Air Door Actuator / Motor: Description and Operation Mode Door Actuator
MODE DOOR ACTUATOR - FRONT
The mode door actuator is a reversible, 12-volt Direct Current (DC), servo motor. The single mode
door actuator is located on the driver side end of the heater-A/C housing unit, close to the top of
the distribution housing. The mode door actuator is mechanically connected to the mode door. The
mode door actuator is interchangeable with the actuators for the blend air door(s) and the
recirculation air door. Each actuator is contained within an identical black molded plastic housing
with an integral wire connector receptacle. Two integral mounting tabs allow the actuator to be
secured with two screws to the heater-A/C unit housing. Each actuator also has an identical output
shaft with splines that connects it to the linkage that drives the mode door. The mode door actuator
does not require mechanical indexing to the mode door linkage, as it is electronically calibrated by
the heater-A/C control module. The mode door actuator cannot be adjusted or repaired and, if
damaged or faulty, it must be replaced.
The mode door actuator is connected to the heaterA/C control module through the vehicle electrical
system by a dedicated two-wire take out and connector of the HVAC wire harness. The mode door
actuator can move the mode door in two directions. When the heater-A/C control module pulls the

ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the
Diagnosis and Testing. For complete circuit diagrams, refer to Overhead Console in the Contents
of Wiring Diagrams.
Sensor Test
1. Turn the ignition switch to the OFF position. Disconnect and isolate the battery negative cable.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Blower Motor: Description and Operation
BLOWER MOTOR - FRONT
The blower motor and blower wheel are located in the passenger side end of the heater-A/C
housing, below the glove box. The blower motor controls the velocity of air flowing through the
heater-A/C housing by spinning a squirrel cage-type blower wheel within the housing at the
selected speed. The blower motor and blower wheel can only be serviced with the heater-A/C
housing removed from the passenger compartment.
The blower motor will only operate when the ignition switch is in the ON position, and the
heater-A/C mode control switch knob is in any position, except OFF. The blower motor receives a
fused battery feed through the blower motor relay (Voltage Reduction Relay or VRR) whenever the
ignition switch is in the ON position.
The blower motor battery feed circuit is protected by a fuse in the Power Distribution Center (PDC).
The blower motor relay control circuit is protected by a fuse in the junction block. Blower motor
speed is controlled by regulating the ground path through the heater-A/C mode control switch, the
blower motor switch, the blower motor resistor, the blower motor relay (VRR), and the high speed
blower motor relay.
The blower motor and blower motor wheel cannot be repaired and, if faulty or damaged, they must
be replaced. The blower motor and blower wheel are each serviced separately.
BLOWER MOTOR - REAR
The rear blower motor and blower wheel are located inside the rear heater-A/C unit, which is
located in the right rear quarter panel. The blower motor controls the velocity of air flowing through
the rear heater-A/C unit by spinning a wide squirrel cage-type blower wheel within the housing at
the selected speed. Rear blower motor speed is controlled by regulating the ground path through
the rear blower motor switch and the rear blower motor resistor.
The rear blower motor will only operate when the ignition switch is in the On position and the front
heater-A/C control is set to either front control of rear heater-A/C unit or the rear control position of
the rear heater-A/C unit. The rear blower motor receives a fused battery feed through a fuse in the
relay and fuse block whenever the ignition switch is in the ON position. The relay and fuse block is
attached to the back of the junction block, under the left side of the instrument panel in the
passenger compartment.
The rear blower motor, blower wheel, and blower wheel housing cannot be repaired and, if faulty or
damaged, they must be replaced as a complete factory-balanced unit.

Blower Motor Resistor: Description and Operation
BLOWER MOTOR RESISTOR BLOCK - FRONT
During vehicle assembly, the blower motor resistor is mounted to the HVAC unit inside the
passenger compartment. It can be accessed from the passenger foot well area. See Blower Motor
Resistor in the Removal and Installation for more information.
Fig. 1 Rear Blower Motor Wheel/Resistor
The blower motor resistor for the optional rear A/C unit is located within the unit housing. The
resistor has multiple resistor wires, each of which will change the resistance in the blower motor
ground path to change the blower motor speed. The blower motor switch located in the A/C control
head directs the ground path through the correct resistor wire to obtain the selected blower motor
speed.
The resistor has multiple resistor circuits each of which will change the resistance in the blower
motor ground path to change the blower motor speed. The blower motor switch directs the ground
path through the correct resistor circuit to obtain the selected blower motor speed.
With the blower motor switch in the lowest speed position, the ground path for the motor is applied
through all of the resistor circuits. Each higher speed selected with the blower motor switch applies
the blower motor ground path through fewer of the resistor circuits, increasing the blower motor
speed.
The blower motor resistor cannot be repaired and, if faulty or damaged, it must be replaced.

Compressor Clutch: Description and Operation
Fig. 1 Compressor Clutch - Typical
A/C COMPRESSOR CLUTCH - FORNT
The compressor clutch assembly consists of a stationary electromagnetic coil, a hub bearing and
pulley assembly, and a clutch plate. The electromagnetic coil unit and the hub bearing and pulley
assembly are each retained on the nose of the compressor front housing with snap rings. The
clutch plate is mounted to the compressor shaft and secured with a nut.
These components provide the means to engage and disengage the compressor from the engine
serpentine accessory drive belt. When the clutch coil is energized, it magnetically draws the clutch
into contact with the pulley and drives the compressor shaft. When the coil is not energized, the
pulley freewheels on the clutch hub bearing, which is part of the pulley. The compressor clutch and
coil are the only serviced parts on the compressor.
The compressor clutch engagement is controlled by several components: the heater-A/C mode
control switch, the evaporator temperature sensor, the loss of charge cut-off switch, the pressure
transducer, the compressor clutch relay, and the Powertrain Control Module (PCM). The PCM may
delay compressor clutch engagement for up to thirty seconds. Refer to Fuel System for more
information on the PCM controls.

Compressor Clutch: Testing and Inspection
Examine the friction surfaces of the clutch pulley and the front plate for wear. The pulley and front
plate should be replaced if there is excessive wear or scoring.
If the friction surfaces are oily, inspect the shaft and nose area of the compressor for oil. Remove
the felt from the front cover. If the felt is saturated with oil, the shaft seal is leaking and the
compressor must be replaced.
Check the clutch pulley bearing for roughness or excessive leakage of grease. Replace the
bearing, if required.

Compressor Clutch Coil: Testing and Inspection
The battery must be fully-charged before performing the following tests. Refer to Battery for more
information.
1. Connect an ammeter (0 to 10 ampere scale) in series with the clutch coil terminal. Use a
voltmeter (0 to 20 volt scale) with clip-type leads for
measuring the voltage across the battery and the compressor clutch coil.
2. With the heater-A/C mode control switch in any A/C mode, and the blower motor switch in the
lowest speed position, start the engine and run it at
normal idle.
3. The compressor clutch coil voltage should read within two volts of the battery voltage. If there is
voltage at the clutch coil, but the reading is not
within two volts of the battery voltage, test the clutch coil feed circuit for excessive voltage drop and
repair as required. If there is no voltage reading at the clutch coil, use a DRB scan tool and the
proper Diagnostic Procedures for testing of the compressor clutch circuit. The following
components must be checked and repaired as required before you can complete testing of the
clutch coil: Fuses in the junction block and the Power Distribution Center (PDC)
- Heater-A/C mode control switch
- Compressor clutch relay
- Evaporator temperature sensor
- Pressure transducer
- Loss of charge
- Powertrain Control Module (PCM).
4. The compressor clutch coil is acceptable if the current draw measured at the clutch coil is 2.0 to
3.9 amperes with the electrical system voltage at
11.5 to 12.5 volts. This should only be checked with the work area temperature at 21 °C (70 °F). If
system voltage is more than 12.5 volts, add electrical loads by turning on electrical accessories
until the system voltage drops below 12.5 volts. a. If the clutch coil current reading is four amperes
or more, the coil is shorted and should be replaced. b. If the clutch coil current reading is zero, the
coil is open and should be replaced.

Compressor Clutch Relay: Description and Operation
COMPRESSOR CLUTCH RELAY - FRONT
The compressor clutch relay is an International Standards Organization (ISO) micro-relay. The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay.
The compressor clutch relay is an electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the evaporator

RELAY TEST
The compressor clutch relay is located in the Power Distribution Center (PDC). Refer to the PDC
label for relay identification and location. Remove the relay from the PDC to perform the following
tests: 1. A relay in the de-energized position should have continuity between terminals 87A and 30,
and no continuity between terminals 87 and 30. If OK,
go to Step 2. If not OK, replace the faulty relay.
2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 3. If not OK, replace the faulty relay. 3. Connect a battery to terminals 85 and 86.
There should now be continuity between terminals 30 and 87, and no continuity between terminals
87A and 30. If OK, see the Relay Circuit Test below. If not OK, replace the faulty relay.
RELAY CIRCUIT TEST
1. The relay common feed terminal cavity (30) is connected to fused battery feed. There should be
battery voltage at the cavity for relay terminal 30
at all times. If OK, go to Step 2. If not OK, repair the open circuit to the fuse in the PDC as required.
2. The relay normally closed terminal (87A) is not used in this application. Go to Step 3. 3. The
relay normally open terminal cavity (87) is connected to the compressor clutch coil. There should
be continuity between this cavity and the
A/C compressor clutch relay output circuit cavity of the compressor clutch coil wire harness
connector. If OK, go to Step 4. If not OK, repair the open circuit as required.
4. The relay coil battery terminal (86) is connected to the fused ignition switch output (run/start)
circuit. There should be battery voltage at the cavity
for relay terminal 86 with the ignition switch in the ON position. If OK, go to Step 5. If not OK, repair
the open circuit to the fuse in the junction block as required.
5. The coil ground terminal cavity (85) is switched to ground through the Powertrain Control Module
(PCM). There should be continuity between
this cavity and the A/C compressor clutch relay control circuit cavity of the PCM wire harness
connector C (gray) at all times. If not OK, repair the open circuit as required.

Condenser HVAC: Description and Operation
A/C CONDENSOR - FRONT
The condenser is a heat exchanger that allows the high-pressure refrigerant gas being discharged
by the compressor to give up its heat to the air passing over the condenser fins, thus causing the
refrigerant to change to a liquid state.
When the refrigerant gas gives up its heat, it condenses. When the refrigerant leaves the
condenser, it has become a high-pressure liquid refrigerant. The volume of air flowing over the
condenser fins is critical to the proper cooling performance of the air conditioning system.
Therefore, it is important that there are no objects placed in front of the radiator grille openings in
the front of the vehicle or foreign material on the condenser fins that might obstruct proper air flow.
Also, any factory-installed air seals or shrouds must be properly reinstalled following radiator or
condenser service.
The condenser cannot be repaired and, if faulty or damaged, it must be replaced.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information >
Diagrams > Diagram Information and Instructions > Page 5903
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information >
Diagrams > Diagram Information and Instructions > Page 5904
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.
Circuit Information
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information >
Diagrams > Diagram Information and Instructions > Page 5905
Wire Code Identification
Wire Color Code Chart
Each wire shown in the diagrams contains a code which identifies the main circuit, part of the main
circuit, gauge of wire, and color.
Connector, Ground and Splice Information
CAUTION: Not all connectors are serviced. Some connectors are serviced only with a harness. A
typical example might be the Supplemental Restraint System connectors. Always check parts
availability before attempting a repair.
IDENTIFICATION
Connectors, grounds, and splices are identified as follows: In-line connectors located in the engine compartment are C100 series numbers
- In-line connectors located in the Instrument Panel area are C200 series numbers.
- In-line connectors located in the body are C300 series numbers.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Heating and Air Conditioning > Control Assembly, HVAC > Component Information >
Diagrams > Diagram Information and Instructions > Page 5906
- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.
WARNING:
- ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION.
- USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
- BE SURE THAT THE IGNITION SWITCH ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.
Diode Replacement
REMOVAL
1. Disconnect the battery. 2. Locate the diode in the harness, and remove the protective covering.

Control Assembly: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Coupler HVAC: Description and Operation
REFRIGERANT LINE COUPLER - FRONT
Spring-lock type refrigerant Line couplers are used to connect many of the refrigerant hues and
other components to the refrigerant system. These couplers require a special tool for disengaging
the two coupler halves.
Fig. 4 Spring-Lock Coupler - Typical
The spring-lock coupler is held together by a garter spring inside a circular cage on the male half of
the fitting. When the two coupler halves are connected, the flared end of the female fitting slips
behind the garter spring inside the cage on the male fitting. The garter spring and cage prevent the
flared end of the female fitting from pulling out of the cage.
Two O-rings on the male half of the fitting are used to seal the connection. These O-rings are
compatible with R-134a refrigerant and must be replaced with O-rings made of the same material.
Secondary clips are installed over the two connected coupler halves at the factory for added
blowoff protection.

a. If the garter spring is missing, install a new spring by pushing it into the coupler cage opening. b.
If the garter spring is damaged, remove it from the coupler cage with a small wire hook (DO NOT
use a screwdriver) and install a new garter
spring.
2. Clean any dirt or foreign material from both halves of the coupler fitting. 3. Install new O-rings on
the male half of the coupler fitting.
CAUTION: Use only the specified O-rings as they are made of a special material for the R-134a
system. The use of any other O-rings may allow the connection to leak intermittently during vehicle
operation.
4. Lubricate the male fitting and O-rings, and the inside of the female fitting with clean R-134a
refrigerant oil. Use only refrigerant oil of the type
recommended for the compressor in the vehicle.
5. Fit the female half of the coupler fitting over the male half of the fitting. 6. Push together firmly on
the two halves of the coupler fitting until the garter spring in the cage on the male half of the fitting
snaps over the flanged
end on the female half of the fitting.

Hot/Humid > Page 5958
Some vehicle operators may experience a musty odor from the A/C system, primarily at start up in
hot and humid climates. This odor may be the result of microbial growth on the cooling coil. During
normal A/C system operation, condensation forms in and around the NC cooling coil. When
airborne pollutants mix with this condensation, bacteria and fungi growth begins and odor results.
DIAGNOSIS:
If the operator describes, or the technician experiences a musty odor when operating the A/C
system, perform the appropriate Repair Procedure based on the vehicle model.
PARTS REQUIRED:
A/C COOLING COIL CLEANER REQUIREMENTS BY VEHICLE MODEL
EQUIPMENT REQUIRED:
POLICY: Reimbursable within the provisions of the warranty.

Evaporator Core: Locations
The front evaporator coil is located in the heater-A/C housing, under the instrument panel.
The rear evaporator coil is located in the rear heater-A/C unit housing, in the right rear quarter
panel.

Evaporator Core: Description and Operation
A/C EVAPORATOR - FRONT
The evaporator coil is located in the heater-A/C housing, under the instrument panel. The
evaporator coil is positioned in the heater-A/C housing so that all air that enters the housing must
pass over the fins of the evaporator before it is distributed through the system ducts and outlets.
However, air passing over the evaporator coil fins will only be conditioned when the compressor is
engaged and circulating refrigerant through the evaporator coil tubes.
Refrigerant enters the evaporator from the expansion valve as a low-temperature, low-pressure
mixture of liquid and gas. As air flows over the fins of the evaporator, the humidity in the air
condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption
causes the refrigerant to boil and vaporize. The refrigerant becomes a low pressure gas when it
leaves the evaporator.
The evaporator coil cannot be repaired and, if faulty or damaged, it must be replaced.
REAR EVAPORATOR
The rear evaporator coil is located in the rear heater-A/C unit housing, in the right rear quarter
panel. The evaporator coil is positioned in the heater-A/C unit housing so that all air that enters the
housing must pass over the fins of the evaporator before it is distributed through the system
outlets. However, air passing over the evaporator coil fins will only be conditioned when the
compressor is engaged and circulating refrigerant through the evaporator coil tubes.
Refrigerant enters the evaporator from the rear expansion valve as a low-temperature, low
pressure mixture of liquid and gas. As air flows over the fins of the evaporator, the humidity in the
air condenses on the fins, and the heat from the air is absorbed by the refrigerant. Heat absorption
causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas when it
leaves the evaporator. The rear evaporator coil cannot be repaired and, if faulty or damaged, the
rear evaporator coil must be replaced.

Expansion Valve: Description and Operation
A/C EXPANSION VALVE - FRONT
The front "H" valve-type Thermal Expansion Valve (TXV) is located at the dash panel between the
liquid and suction lines, and the evaporator coil. High-pressure, high temperature liquid refrigerant
from the liquid line passes through the expansion valve orifice, converting it into a low-pressure,
low-temperature mixture of liquid and gas before it enters the evaporator coil.
The expansion valve control head monitors the temperature and pressure of the refrigerant leaving
the evaporator coil through the suction line, and adjusts the orifice size at the liquid line to let the
proper amount of refrigerant into the evaporator coil to meet the vehicle cooling requirements.
Controlling the refrigerant flow through the evaporator ensures that none of the refrigerant leaving
the evaporator is still in a liquid state, which could damage the compressor.
The expansion valve is a factory calibrated unit and cannot be adjusted or repaired. If faulty or
damaged, the expansion valve must be replaced.
REAR EXPANSION VALVE
Vehicles equipped with the optional rear A/C unit have an H-type thermal expansion valve (TXV)
located on the rear HVAC unit, behind the passenger side rear quarter trim panel. It performs the
same function as the front expansion valve, to monitor refrigerant temperature and pressure at the
control head and meter the refrigerant entering the evaporator to meet the vehicle cooling
requirements.
The rear expansion valve is a factory calibrated unit and cannot be adjusted or repaired. If faulty or
damaged, the rear expansion valve unit must be replaced.

Expansion Valve: Testing and Inspection
These tests must be made at an ambient temperature of 21 to 29 °C (70 to 85 °F). Disconnect the
wire connector at the low pressure cut off switch. Use a jumper wire to jumper terminals at the
connector.
Front (Only)
1. Attach a manifold gauge set or an approved A/C Recharging/Recycling Station. Close the
vehicle doors and windows, start the engine, and hold
the engine speed at 1,000 rpm. Set the heater-A/C mode control switch knob to the recirculation
mode (Max A/C) position, the temperature control knob to the full hot position, and the blower
motor switch to the highest speed position.
2. Operate the air conditioning system for at least five minutes to stabilize the system, and to
provide sufficient reheat to load the evaporator. The
discharge pressure (high side) at the service port should reach 966 to 1656 kPa (140 to 240 psi). If
this discharge pressure cannot be obtained, check the refrigerant system charge.
WARNING: EXTREME CARE MUST BE USED WHEN HANDLING LIQUID CARBON DIOXIDE
(CO), AS SKIN INJURY CAN OCCUR. PROTECTIVE GLOVES SHOULD BE WORN.
3. Apply liquid Carbon Dioxide (CO) to the expansion valve control head (completely cover the
head) for a minimum of thirty seconds. Observe
the manifold gauge set. The suction pressure (low side) must drop to below 50 kPa (7.25 psi). If
this reading is not obtained, the expansion valve is faulty and must be replaced.
4. Remove the liquid carbon dioxide (CO) from the control head. Observe the manifold gauge set.
The suction pressure (low side) must increase to a
minimum of 262 kPa (38 psi), and then stabilize to a pressure of 172 to 240 kPa (25 to 35 psi). If
these readings are not obtained, the expansion valve is faulty and must be replaced.
5. Set the engine idle speed at 1,000 rpm and the blower motor switch to the highest speed
position. The suction pressure (low side) should be 138 to
207kPa (20 to 30 psi). If the discharge pressure (high side) is higher than 1656 kPa (240 psi),
check for a restricted discharge line. Also check the engine cooling system for overheating, air
trapped in the system, or a faulty fan drive. If the discharge pressure (high side) is less than 966
kPa (140 psi), check for a faulty compressor.
Front And Rear A/C
1. Attach a manifold gauge set or an approved A/C Recharging/Recycling Station. Close the
vehicle doors and windows, start the engine, and hold
the engine speed at 1,000 rpm. Set the heater-A/C mode control switch knob to the recirculation
mode (Max A/C) position, the temperature control knob to the full hot position, and both the front
and rear blower motor switches to their highest speed positions.
2. Operate the air conditioning system for at least five minutes to stabilize the system, and to
provide sufficient reheat to load the front and rear
evaporators. The discharge pressure (high side) at the service port should reach 966 to 1656 kPa
(140 to 240 psi). If this discharge pressure cannot be obtained, check the refrigerant system
charge. See Refrigerant System Charge in the Service Procedures.
WARNING: EXTREME CARE MUST BE USED WHEN HANDLING LIQUID CARBON DIOXIDE
(CO) AS SKIN INJURY CAN OCCUR. PROTECTIVE GLOVES SHOULD BE WORN.
3. Both the front and rear expansion valves should be checked for correct operation. Apply liquid
carbon dioxide (CO) to the front expansion valve
control head (completely cover the head) for a minimum of thirty seconds. Observe the manifold
gauge set. The suction pressure (low side) must drop to below 50 kPa (7.25 psi). If this reading is
not obtained, the expansion valve is faulty and must be replaced.
4. Apply liquid carbon dioxide (CO) to the front expansion valve control head (completely cover the
head) for a minimum of thirty seconds.
Remove the protective cover and apply liquid carbon dioxide (CO) to the rear expansion valve
control head. Grasp the suction line (large line) off the evaporator with a bare hand and hold it for
at least two minutes. Use the same procedure with the front expansion valve. Grasp the suction
line jumper below the expansion valve (before the rear suction line tee) with a bare hand and hold
for at least two minutes. When testing the front expansion valve, place the rear blower motor switch
in the OFF position.
5. With a correctly operating expansion valve, the suction line will feel warm with the closing of the
valve (cold applied). Then the line will cool
sharply within two minutes as the valve opens. If this temperature change does not occur, the
expansion valve is faulty and must be replaced.

Heater Core: Description and Operation
HEATER CORE - FRONT
The heater core is located in the HVAC housing, under the instrument panel. It is a heat exchanger
made of rows of tubes and fins.
The heater core is not repairable and if damaged it must be replaced.
Engine coolant is circulated through heater hoses to the heater core at all times. As the coolant
flows through the heater core, heat removed from the engine is transferred to the heater core fins
and tubes. Air directed through the heater core picks up the heat from the heater core fins. The
blend door allows control of the heater output air temperature by controlling how much of the air
flowing through the HVAC housing is directed through the heater core. The blower motor speed
controls the volume of air flowing through the HVAC housing.
The heater core cannot be repaired and, if faulty or damaged, it must be replaced.
REAR HEATER CORE
The rear heater core is located in the heater-A/C housing in the right rear inside quarter panel. It is
a heat exchanger made of rows of tubes and fins. The heater core is not repairable and if damaged

Description and Operation
High Pressure Safety Valve HVAC: Description and Operation
A/C COMPRESSOR HIGH PRESSURE RELIEF VALVE - FORNT
A high pressure relief valve is located on the compressor cylinder head, which is at the rear of the
compressor. This mechanical valve is designed to vent refrigerant from the system to protect
against damage to the compressor and other system components, caused by condenser air flow
restriction or an overcharge of refrigerant.
The high pressure relief valve vents the system when a discharge pressure of 3445 to 4135 kPa
(500 to 600 psi) or above is reached. The valve closes with a minimum discharge pressure of 2756
kPa (400 psi) is reached.
The high pressure relief valve vents only enough refrigerant to reduce the system pressure, and
then re-seats itself. The majority of the refrigerant is conserved in the system. If the valve vents
refrigerant, it does not mean the valve is faulty.
The high pressure relief valve is a factory-calibrated unit. The valve cannot be adjusted or repaired,
and must not be removed or otherwise disturbed. The valve is only serviced as a part of the
compressor assembly.

Hose/Line HVAC: Service Precautions
Kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire system. High
pressures are produced in the system when it is operating. Extreme care must be exercised to
make sure that all refrigerant system connections are pressure tight.
A good rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times
the diameter of the hose. Sharp bends will reduce the flow of refrigerant. The flexible hose lines
should be routed so they are at least 80 millimeters (3 inches) from the exhaust manifold. It is a
good practice to inspect all flexible refrigerant system hose lines at least once a year to make sure
they are in good condition and properly routed.
There are two types of refrigerant fittings:
- All fittings with O-rings need to be coated with refrigerant oil before installation. Use only O-rings
that are the correct size and approved for use with R-134a refrigerant. Failure to do so may result
in a leak.
- Unified plumbing connections with gaskets cannot be serviced with O-rings. The gaskets are not
reusable and new gaskets do not require lubrication before installing.
Using the proper tools when making a refrigerant plumbing connection is very important. Improper
tools or improper use of the tools can damage the refrigerant fittings.
The refrigerant must be recovered completely from the system before opening any fitting or
connection. Open the fittings with caution, even after the refrigerant has been recovered. If any
pressure is noticed as a fitting is loosened, tighten the fitting and recover the refrigerant from the
system again.
Do not discharge refrigerant into the atmosphere. Use an R-134a refrigerant recovery/recycling
device that meets SAE Standard J2210.
The refrigerant system will remain chemically stable as long as pure, moisture-free R-134a
refrigerant and refrigerant oil is used. Dirt, moisture, or air can upset this chemical stability.
Operational troubles or serious damage can occur if foreign material is present in the refrigerant
system.
When it is necessary to open the refrigerant system, have everything needed to service the system
ready. The refrigerant system should not be left open to the atmosphere any longer than
necessary. Cap or plug all lines and fittings as soon as they are opened to prevent the entrance of
dirt and moisture. All lines and components in parts stock should be capped or sealed until they are
to be installed.
All tools, including the refrigerant recycling equipment, the manifold gauge set, and test hoses
should be kept clean and dry. All tools and equipment must be designed for R-134a refrigerant.

Hose/Line HVAC: Description and Operation
REFRIGERANT LINES
The refrigerant lines and hoses are used to carry the refrigerant between the various air
conditioning system components. A barrier hose design with a nylon tube, which is sandwiched
between rubber layers, is used for the R-134a air conditioning system on this vehicle. This nylon
tube helps to further contain the R-134a refrigerant, which has a smaller molecular structure than
R-12 refrigerant. The ends of the refrigerant hoses are made from lightweight aluminum or steel,
and commonly use braze-less fittings.
Any kinks or sharp bends in the refrigerant plumbing will reduce the capacity of the entire air
conditioning system. Kinks and sharp bends reduce the flow of refrigerant in the system. A good
rule for the flexible hose refrigerant lines is to keep the radius of all bends at least ten times the
diameter of the hose. In addition, the flexible hose refrigerant lines should be routed so they are at
least 80 millimeters (3 inches) from the exhaust manifold.
High pressures are produced in the refrigerant system when the air conditioning compressor is
operating. Extreme care must be exercised to make sure that each of the refrigerant system
connections is pressure-tight and leak free. It is a good practice to inspect all flexible hose
refrigerant lines at least once a year to make sure they are in good condition and properly routed.
The refrigerant lines and hoses are coupled with other components of the HVAC system with
peanut-block style fittings. A stat-O seal type flat steel gasket with a captured compressible O-ring,
is used to mate plumbing lines with A/C components to ensure the integrity of the refrigerant
system.
The refrigerant lines and hoses cannot be repaired and, if faulty or damaged, they must be
replaced.

Receiver Dryer: Description and Operation
RECEIVER/DRIER - FORNT
The filter-drier is mounted on the right front wheelhouse front extension in the engine compartment,
in the liquid line between the condenser outlet and the evaporator inlet. Refrigerant enters the
filter-drier as a high-pressure, high-temperature liquid.
The filter-drier performs a filtering action to prevent foreign material in the refrigerant from
contaminating the expansion valve. A desiccant bag is mounted inside the filter-drier canister to
absorb any moisture which may have entered and become trapped within the refrigerant system. In
addition, during periods of high demand air conditioner operation, the filter-drier acts as a reservoir
to store surplus refrigerant.
The filter-drier cannot be repaired. If the filter- drier is faulty or damaged, or if the refrigerant system
has been contaminated or left open to the atmosphere for an indeterminable period, it must be
replaced.

Refrigerant: Service Precautions
R-134a - R-12
Because R-134a refrigerant is a hydrofluorocarbon (HFC) which contains hydrogen atoms in place
of chlorine atoms, it will not cause damage to the ozone layer.
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone layer, Chrysler
Corporation recommends an R-134a refrigerant recycling device.
The Clean Air Act Amendment of 1990 requires that Freon be recovered when accessing the air
conditioning circuit and that technicians hold a refrigerant recovery and handling certification.
The Ozone Layer A thin layer of ozone molecules, located 10 to 30 miles above the earth, form a
protective cover by absorbing a portion of the ultraviolet (UV) radiation emitted from the Sun.
Ozone Depletion Scientific research performed over the past 15 years links the release of
chlorofluorocarbons (CFC)s, also know by the trade name Freon) into the atmosphere to ozone
depletion. When CFCs are released into the atmosphere, they eventually reach the ozone layer
located in the stratosphere where they react with and destroy ozone molecules.
Harmful Effects Ozone depletion and the corresponding increase in UV radiation has been shown
to lead to higher incidents of cancer as well as global warming. When viewed from a global
perspective, ozone depletion holds an enormous potential for damage.
Upper Level vs. Ground Level Ozone Confusion often arises when we hear about the necessity of
the ozone layer and ground level ozone. The ozone layer existing high above the earth is beneficial
but the same compound, when located at ground level, is harmful to humans, animals, crops and
vegetation.
Ground level ozone is a component of smog and forms when hydrocarbons (HC) react with
nitrogen oxides (NOx) in the presence of sunlight and heat.
Montreal Protocol In response to the growing body of evidence demonstrating the detrimental
effects of (CFC)s, 24 countries and the European community met in Montreal, Canada, in 1987 to
establish standards for the control of (CFC)s. Since that time, a total of 132 countries have become
signatories to this agreement leading to an end of production of R12 in December, 1995, in all
developed countries.
As established by the Montreal Protocol, R12 production in developed countries has ceased.
Clean Air Act The United States Congress, acting in response to the Montreal Protocol, banned
production of (CFC)s by the year 2000. Congress also amended the Clean Air Act in an effort to
control both the production and use of (CFC)s for refrigerant applications including mobile vehicle
air conditioning systems.

Refrigerant: Description and Operation
REFRIGERANT
The refrigerant used in this air conditioning system is a HydroFluoroCarbon (HFC), type R-134a.
Unlike R-12, which is a ChloroFluoroCarbon (CFC), R-134a refrigerant does not contain
ozone-depleting chlorine. R-134a refrigerant is a non-toxic, non-Hammable, clear, and colorless
liquefied gas.
Even though R-134a does not contain chlorine, it must be reclaimed and recycled just like
CFC-type refrigerants. This is because R-134a is a greenhouse gas and can contribute to global
warming.
R-134a refrigerant is not compatible with R-12 refrigerant in an air conditioning system. Even a
small amount of R-12 added to an R-134a refrigerant system will cause compressor failure,
refrigerant oil sludge or poor air conditioning system performance. In addition, the PolyAlkylene
Glycol (PAG) synthetic refrigerant oils used in an R-134a refrigerant system are not compatible
with the mineral-based refrigerant oils used in an R-12 refrigerant system.
R-134a refrigerant system service ports, service tool couplers and refrigerant dispensing bottles
have all been designed with unique fittings to ensure that an R-134a system is not accidentally
contaminated with the wrong refrigerant (R-12). There are also labels posted in the engine
compartment of the vehicle and on the compressor identifying to service technicians that the air
conditioning system is equipped with R-134a.

Refrigerant: Testing and Inspection
If the air conditioning system does not cool properly, the A/C system performance should be tested.
See A/C Performance for the procedures. If the A/C system refrigerant fill is found to be low or if
the system is empty; a leak at a refrigerant line, connector fitting, component, or component seal is
likely.
An electronic leak detector designed for R-134a refrigerant, or a fluorescent R-134a leak detection
dye and a black light are recommended for locating and confirming refrigerant system leaks. Refer
to the operating instructions supplied by the equipment manufacturer for the proper care and use of
this equipment.
NOTE: A/C SYSTEM ALREADY CONTAINS A FACTORY INSTALLED FLUORESCENT DYE.
An oily residue on or near refrigerant system lines, connector fittings, components, or component
seals can indicate the general location of a possible refrigerant leak. However, the exact leak
location should be confirmed with an electronic leak detector prior to component repair or
replacement.
To detect a leak in the refrigerant system with an electronic leak detector, perform one of the
following procedures:
SYSTEM EMPTY
1. Evacuate the refrigerant system. 2. Connect and dispense 0.283 kilograms (0.625 pounds or 10
ounces) of R-134a refrigerant into the evacuated refrigerant system. 3. Position the vehicle in a
wind-free work area. This will aid in detecting small leaks. 4. With the engine not running, use an
electronic R-134a leak detector and search for leaks. Because R-134a refrigerant is heavier than
air, the leak
detector probe should be moved slowly along the bottom side of all refrigerant lines, connector
fittings and components.
5. To inspect the front evaporator coil for leaks, insert the electronic leak detector probe into the
center instrument panel outlet and the floor duct
outlet. Set the front blower motor switch to the lowest speed position, and the mode control switch
to the recirculation mode (Max-A/C).
6. To inspect for leaks in the rear evaporator, put the rear system in the floor mode and place the
probe in the rear unit floor outlet.
SYSTEM LOW
1. Position the vehicle in a wind-free work area. This will aid in detecting small leaks. 2. Bring the
refrigerant system up to operating temperature and pressure. This is done by allowing the engine
to run with the air conditioning system
turned on for five minutes.
3. With the engine not running, use an electronic R-134a leak detector and search for leaks.
Because R-134a refrigerant is heavier than air, the leak
detector probe should be moved slowly along the bottom side of all refrigerant lines, connector
fittings and components.
4. To inspect the evaporator coil for leaks, insert the electronic leak detector probe into the center
instrument panel outlet and the floor duct outlet.
Set the front blower motor switch to the lowest speed position, and the mode control switch to the
recirculation mode (Max-A/C).
5. To detect a leak in the rear evaporator, put the rear system in the floor mode and place the
probe in the rear unit floor outlet.

Refrigerant: Service and Repair Refrigerant - Recovery
A R-134a refrigerant recovery/recycling/charging station that meets SAE Standard J22 10 must be
used to recover the refrigerant from an R-134a refrigerant system. Refer to the operating
instructions supplied by the equipment manufacturer for the proper care and use of this equipment.

Refrigerant: Service and Repair Refrigerant - Evacuate
If the refrigerant system has been open to the atmosphere, it must be evacuated before the system
can be charged. If moisture and air enters the system and becomes mixed with the refrigerant, the
compressor head pressure will rise above acceptable operating levels. This will reduce the
performance of the air conditioner and damage the compressor. Evacuating the refrigerant system
will remove the air and boil the moisture out of the system at near room temperature. To evacuate
the refrigerant system, use the following procedure:
1. Connect a R-134a refrigerant recovery/recycling/charging station that meets SAE Standard
J2210 and a manifold gauge set to the refrigerant
system of the vehicle.
2. Open the low and high side valves and start the charging station vacuum pump. When the
suction gauge reads 88 kPa (26 in. Hg.) vacuum or
greater, close all of the valves and turn OFF the vacuum pump. a. If the refrigerant system fails to
reach the specified vacuum, the system has a leak that must be corrected. See Refrigerant System
Leaks in the
Diagnosis and Testing for the procedures.
b. If the refrigerant system maintains the specified vacuum for five minutes, restart the vacuum
pump, open the suction and discharge valves and
evacuate the system for an additional ten minutes.
3. Close all of the valves, and turn OFF the charging station vacuum pump. 4. The refrigerant
system is now ready to be charged with R-134a refrigerant. See Refrigerant System Charge in the
Service Procedures.

Refrigerant Oil: Service and Repair
REFRIGERANT OIL - FRONT
The refrigerant oil used in R-134a refrigerant systems is a synthetic-based, PolyAlkylene Glycol
(PAG), wax-free lubricant. Mineral-based R-12 refrigerant oils are not compatible with PAG Oils
and should never be introduced to an R-134a refrigerant system.
There are different PAG oils available, and each contains a different additive package. The
SD7H15 compressor used in this vehicle is designed to use an SP-20 PAG refrigerant oil. Use only
refrigerant oil of this same type to service the refrigerant system.
After performing any refrigerant recovery or recycling operation, always replenish the refrigerant
system with the same amount of the recommended refrigerant oil as was removed. Too little
refrigerant oil can cause compressor damage, and too much can reduce air conditioning system
performance.
PAG refrigerant oil is much more hygroscopic than mineral oil, and will absorb any moisture it
comes into contact with, even moisture in the air. The PAG oil container should always be kept
tightly capped until it is ready to be used. After use, recap the oil container immediately to prevent
moisture contamination.
REFRIGERANT OIL LEVEL - FRONT
When an air conditioning system is assembled at the factory, all components except the
compressor are refrigerant oil free. After the refrigerant system has been charged and operated,
the refrigerant oil in the compressor is dispersed throughout the refrigerant system. The
evaporator, filter-drier, condenser, and compressor will each retain a significant amount of the
needed refrigerant oil.
It is important to have the correct amount of oil in the refrigerant system. This ensures proper
lubrication of the compressor. Too little oil will result in damage to the compressor. Too much oil
will reduce the cooling capacity of the air conditioning system.
It will not be necessary to check the oil level in the compressor or to add oil, unless there has been
an oil loss. An oil loss may occur due to a rupture or leak from a refrigerant line, a connector fitting,
a component, or a component seal. If a leak occurs, add 30 milliliters (1 fluid ounce) of refrigerant
oil to the refrigerant system after the repair has been made. Refrigerant oil loss will be evident at
the leak point by the presence of a wet, shiny surface around the leak.
Refrigerant Oil Capacities Chart
Refrigerant oil must be added when a filter-drier, evaporator coil, or condenser are replaced. See
the Refrigerant Oil Capacities chart. When a compressor is replaced, the refrigerant oil must be
drained from the old compressor and measured. Drain all of the refrigerant oil from the new
compressor, then fill the new compressor with the same amount of refrigerant oil that was drained
out of the old compressor.

Low Pressure Sensor / Switch: Description and Operation
LOSS OF CHARGE SWITCH - FRONT
This vehicle is equipped with a Loss of Charge Switch. This switch is screwed onto a fitting on the
suction jumper line between the evaporator and the low side refrigerant system service port. The
switch is used to measure if refrigerant system pressure goes too low. It is not responsible for
cycling the A/C compressor clutch.
The loss of charge switch is connected in series electrically with the Heater-A/C controls between
ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the
PCM to turn the compressor clutch ON and OFF. This prevents compressor operation when the
system charge is low and prevents damage to the compressor. The switch opens with a pressure
of 7 to 13 psi and closes when the pressure rises to 15 to 25 psi.

Dodge Workshop Manuals > Heating and Air Conditioning > Refrigerant Pressure Sensor / Switch, HVAC > Low Pressure
Sensor / Switch, HVAC > Component Information > Specifications > Page 6076
Low Pressure Sensor / Switch: Testing and Inspection
Before performing diagnosis of the loss of charge switch, be certain that the switch is properly
installed on the suction jumper line fitting. If the switch is too loose it may not open the
Schrader-type valve in the accumulator fitting, which will prevent the switch from correctly
monitoring the refrigerant system pressure. Remember that lower ambient temperatures during
cold weather will open the switch contacts and prevent compressor operation due to the
pressure/temperature relationship of the refrigerant. Also verify that the refrigerant system has the
correct refrigerant charge.
1. Disconnect and isolate the battery negative cable. 2. Unplug the a/c loss of charge switch wire
harness connector from the switch on the refrigerant system fitting. 3. Install a jumper wire between
the two cavities of the loss of charge switch harness connector. 4. Connect a manifold gauge set to
the refrigerant system service ports. 5. Connect the battery negative cable. 6. Place the heater-A/C
mode control switch knob in any A/C position and start the engine. 7. Check for continuity between
the two terminals of the loss of charge switch. There should be continuity with a suction pressure
reading of 7 to 13
psi. If OK, test and repair the A/C switch sense circuit as required. If not OK, replace the faulty
switch.

Compressor Clutch Relay: Description and Operation
COMPRESSOR CLUTCH RELAY - FRONT
The compressor clutch relay is an International Standards Organization (ISO) micro-relay. The
terminal designations and functions are the same as a conventional ISO relay. However, the
micro-relay terminal orientation (footprint) is different, the current capacity is lower, and the relay
case dimensions are smaller than those of the conventional ISO relay.
The compressor clutch relay is an electromechanical device that switches battery current to the
compressor clutch coil when the Powertrain Control Module (PCM) grounds the coil side of the
relay. The PCM responds to inputs from the heater-A/C mode control switch, the evaporator
temperature sensor, the loss of charge switch, and the pressure transducer. See Compressor
Clutch Relay in the Diagnosis and Testing for more information.
The compressor clutch relay is located in the Power Distribution Center (PDC) in the engine
compartment. Refer to the PDC label for relay identification and location.
The compressor clutch relay cannot be repaired and, if faulty or damaged, it must be replaced.

Ambient Temperature Sensor / Switch HVAC: Description and Operation
AMBIENT TEMP SENSOR - FRONT
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Ambient Temperature Sensor / Switch HVAC: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the

Low Pressure Sensor / Switch: Description and Operation
LOSS OF CHARGE SWITCH - FRONT
This vehicle is equipped with a Loss of Charge Switch. This switch is screwed onto a fitting on the
suction jumper line between the evaporator and the low side refrigerant system service port. The
switch is used to measure if refrigerant system pressure goes too low. It is not responsible for
cycling the A/C compressor clutch.
The loss of charge switch is connected in series electrically with the Heater-A/C controls between
ground and the Powertrain Control Module (PCM). The switch contacts open and close causing the
PCM to turn the compressor clutch ON and OFF. This prevents compressor operation when the
system charge is low and prevents damage to the compressor. The switch opens with a pressure
of 7 to 13 psi and closes when the pressure rises to 15 to 25 psi.

Switch, HVAC > Low Pressure Sensor / Switch, HVAC > Component Information > Specifications > Page 6118
Low Pressure Sensor / Switch: Testing and Inspection
Before performing diagnosis of the loss of charge switch, be certain that the switch is properly
installed on the suction jumper line fitting. If the switch is too loose it may not open the
Schrader-type valve in the accumulator fitting, which will prevent the switch from correctly
monitoring the refrigerant system pressure. Remember that lower ambient temperatures during
cold weather will open the switch contacts and prevent compressor operation due to the
pressure/temperature relationship of the refrigerant. Also verify that the refrigerant system has the
correct refrigerant charge.
1. Disconnect and isolate the battery negative cable. 2. Unplug the a/c loss of charge switch wire
harness connector from the switch on the refrigerant system fitting. 3. Install a jumper wire between
the two cavities of the loss of charge switch harness connector. 4. Connect a manifold gauge set to
the refrigerant system service ports. 5. Connect the battery negative cable. 6. Place the heater-A/C
mode control switch knob in any A/C position and start the engine. 7. Check for continuity between
the two terminals of the loss of charge switch. There should be continuity with a suction pressure
reading of 7 to 13
psi. If OK, test and repair the A/C switch sense circuit as required. If not OK, replace the faulty
switch.

Repairs and Inspections Required After a Collision: Service and Repair Air Bag System
STANDARD PROCEDURE - SERVICE AFTER A PASSIVE RESTRAINT DEPLOYMENT
Any vehicle which is to be returned to use following a passive restraint deployment, must have both
airbags, both seat belt tensioners, the driver airbag trim cover, the horn switch, the clockspring, and
the steering column assembly replaced. These components are not intended for reuse and will be
damaged or weakened as a result of an airbag deployment, which may or may not be obvious
during a visual inspection. Other vehicle components should be closely inspected, but are to be
replaced only as required by the extent of the visible damage incurred.
CLEAN-UP PROCEDURE
Following an airbag deployment, the vehicle interior will contain a powdery residue. This residue
consists primarily of harmless particulate by-products of the small pyrotechnic charge used to
initiate the propellant used to deploy the airbags. However, this residue may also contain traces of
sodium hydroxide powder, a chemical by-product of the propellant material that is used to generate
the nitrogen gas that inflates the airbag. Since sodium hydroxide powder can irritate the skin, eyes,
nose, or throat, be sure to wear safety glasses, rubber gloves, and a long-sleeved shirt during
cleanup (Wear Safety Glasses and Rubber Gloves - Typical).
WARNING: IF YOU EXPERIENCE SKIN IRRITATION DURING CLEANUP, RUN COOL WATER
OVER THE AFFECTED AREA. ALSO, IF YOU EXPERIENCE IRRITATION OF THE NOSE OR
THROAT, EXIT THE VEHICLE FOR FRESH AIR UNTIL THE IRRITATION CEASES. IF
IRRITATION CONTINUES, SEE A PHYSICIAN.
CAUTION: All damaged, faulty, or non-deployed supplemental restraints which are replaced on
vehicles are to be handled and disposed of properly. If an airbag or seat belt tensioner unit is faulty
or damaged and non-deployed, refer to the Hazardous Substance Control System for proper
disposal. Be certain to dispose of all non-deployed and deployed supplemental restraints in a
manner consistent with state, provincial, local and federal regulations.
Begin the cleanup by removing both airbags and both seat belt tensioners from the vehicle. Next,
use a vacuum cleaner to remove any residual powder from the vehicle interior. Clean from outside
the vehicle and work your way inside, so that you avoid kneeling or sitting on a non-cleaned area.
Be certain to vacuum the heater and air conditioning outlets as well (Vacuum Heater and A/C
Outlets - Typical). Run the heater and air conditioner blower on the lowest speed setting and
vacuum any powder expelled from the outlets. You may need to vacuum the interior of the vehicle
a second time to recover all of the powder.

Repairs and Inspections Required After a Collision: Service and Repair Seat Belt System
REPAIRS AND INSPECTIONS REQUIRED AFTER A COLLISION
RESTRAINT SYSTEM
After a impact where an airbag has been deployed due to a collision, the following MUST be
replaced: 1. Front Seat Belts and Retractors (driver and passenger) with integral Tensioners. 2.
After an impact that deploys the airbag, the seat belt tensioner assembly must be replaced.
WARNING: WHEN THE FRONT AIRBAG IS DEPLOYED, THE TENSIONER WILL HAVE
DEPLOYED ALSO AND MUST BE REPLACED.
3. Do not reuse the bolts attaching the seat belt retractor to the seat frame. Failure to follow proper
installation procedure may result in the seat track
latch pins not being synchronized.
4. Inspect the condition of the shoulder/lap belt. replace the retractor if the belt is cut, frayed, torn,
or damaged in any way. The rear seat back
retaining nut also serves as the center seat belt anchor. Be certain to torque this nut.
5. All seat belts should be closely inspected for cuts, tears, fraying, or damage in any way following
any frontal impact or airbag deployment. The
seat belts are to be replaced when visible damage is incurred. Inspect the Lower Anchors and
Tether for Children (LATCH) child restraint anchors for damage after an impact event and replace
as needed.
6. During, and following, any child restraint anchor service, due to impact event or vehicle repair,
carefully inspect all mounting hardware, tether
straps and anchors for proper installation, operation, or damage. if a child restraint anchor is found
damaged in any way, the anchor must be replaced with the seat assembly. failure to do so could
result in occupant personal injury or death.
NOTE: Never attempt to repair a seat belt component. always replace damaged or faulty seat belt
components with the correct, new and unused replacement parts.
VEHICLES EQUIPPED WITH THE OCCUPANT CLASSIFICATION SYSTEM (OCS)
If any of the Occupant Classification System (OCS) components of the passenger side front seat
cushion require replacement, they are serviced only as a factory-calibrated, assembled, and
tamper-evident service replacement package. This package includes the assembled frame,
springs, pad, seat weight bladder and pressure sensor, foam, wiring and a calibrated OCM. When
installing this package, always replace all of the existing components with the new components as
a unit. Do not attempt to separate or disconnect any of the new OCS components contained in the
service replacement package from each other, and do not attempt to reuse any of the replaced
components in this or any other vehicle.
CAUTION: Never replace both the Airbag Control Module (ACM) and the Occupant Classification
Module (OCM) at the same time. If both require replacement, replace one. Then perform the
supplemental restraint verification test before replacing the other. Both the ACM and the OCM
store OCS calibration data, which they transfer to one another when one of them is replaced. If
both are replaced at the same time, an irreversible fault will be set in both modules.

DISCUSSION:
Airbag
When servicing any airbag system, it is essential to follow the proper Service Manual and/or
Diagnostic Manual procedures for diagnosing, testing, and replacing of any component. When
diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the
Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in
conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only
replace the component or wiring that has failed. This will reduce unnecessary cost to the customer
or DaimlerChrysler.
NOTE:
AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN
ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL
WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED.

Clock Springs
Recent analysis of returned clock springs have indicated that prior service may have contributed to
the clock spring's failure.
^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often
used in the clock spring area of the steering column to eliminate noise. Lubricants may have an
adverse effect on the clock spring.
^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the
front wheels will require that the clock spring be centered. This includes clock spring replacement,
steering column service, HVAC service, steering gear service, and front suspension crossmember
service. Refer to the appropriate Service Manual for the clock spring centering procedure.

Air Bag: Description and Operation
Fig. 10 Driver Airbag
Fig.11 Horn Switch
DRIVER AIRBAG
The driver airbag protective trim cover is the most visible part of the driver airbag. The airbag used
in this model is a Next Generation-type that
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Restraint Systems > Air Bag Systems > Air Bag > Component Information > Technical Service
Bulletins > Page 6146
complies with revised federal airbag standards to deploy with less force than those used in some
prior models. The driver airbag is located in the center of the steering wheel, where it is secured
with two screws to the steering wheel armature. Concealed beneath the driver airbag trim cover are
the horn switch, the folded airbag cushion, the airbag retainer or housing, the airbag inflator, and
the retainers that secure the inflator to the airbag housing. The resistive membrane-type horn
switch is secured within a plastic tray that is inserted in a pocket or pouch sewn onto the airbag
cushion retainer strap, between the trim cover and the folded airbag cushion. The airbag inflator is
a conventional non-azide, pyrotechnic-type unit with four studs and it is secured to the stamped
metal airbag housing with four nuts.
The trim cover has an airbag receptacle molded into the back side of it. The four vertical walls of
this receptacle have a total of twelve small windows with blocking tabs that are engaged by twelve
hook formations around the perimeter of the airbag housing. Each hook is inserted through one of
the windows, the integral blocking tab in each window keeps each hook properly engaged with the
trim cover, locking the cover securely into place. One horn switch pigtail wire has an eyelet terminal
connector that is captured beneath a nut and washer on the upper right inflator mounting stud. The
other horn switch pigtail wire is routed between the upper left inflator mounting stud and the inflator,
where it is captured by a small plastic retainer that is pushed onto the stud. The driver airbag
cannot be repaired, and must be replaced if deployed or in any way damaged. The driver airbag
trim cover and the horn switch with tray are available, and may be disassembled from the driver
airbag for service replacement.
The driver airbag is deployed by an electrical signal generated by the Airbag Control Module (ACM)
through the driver airbag line 1 and line 2 (or squib) circuits. When the ACM sends the proper
electrical signal to the airbag inflator, the electrical energy generates enough heat to initiate a small
pyrotechnic charge which, in turn, ignites chemical pellets within the inflator. Once ignited, these
chemical pellets burn rapidly and produce a large quantity of nitrogen gas. The inflator is sealed to
the back of the airbag housing and a diffuser in the inflator directs all of the nitrogen gas into the
airbag cushion, causing the cushion to inflate. As the cushion inflates, the driver airbag trim cover
will split at predetermined breakout lines, then fold back out of the way along with the horn switch
and tray unit. Following an airbag deployment, the airbag cushion quickly deflates by venting the
nitrogen gas towards the instrument panel through the porous fabric material used on the steering
wheel side of the airbag cushion.
Some of the chemicals used to create the nitrogen gas may be considered hazardous in their solid
state, before they are burned, but they are securely sealed within the airbag inflator. However, the
nitrogen gas that is produced when the chemicals are burned is harmless. A small amount of
residue from the burned chemicals may cause some temporary discomfort if it contacts the skin,
eyes, or breathing passages. If skin or eye irritation is noticed, rinse the affected area with plenty of
cool, clean water. If breathing passages are irritated, move to another area where there is plenty of
clean, fresh air to breath. If the irritation is not alleviated by these actions, contact a physician.
PASSENGER AIRBAG
The rearward facing surface of the passenger airbag door above the glove box is the most visible
part of the passenger airbag. The airbag used in this model is a Next Generation-type that
complies with revised federal airbag standards to deploy with less force than those used in some
prior models. The passenger airbag is located in the instrument panel in front of the front seat
passenger seating position, where it is secured to the instrument panel. Concealed beneath the
passenger airbag door are the folded airbag cushion, the airbag retainer or housing, and the airbag
inflator. The airbag inflator is a hybrid-type unit that is secured to and sealed within the airbag
housing along with the folded airbag cushion. The airbag housing is constructed of a long
U-shaped aluminum extrusion with two stamped steel end plates. 'Two tabs that extend from the
bottom of the extrusion serve as the rear mounting brackets, while an angled foot on the bottom of
each end plate serve as the front mounting brackets. The front brackets are secured with screws to
the instrument panel armature above the glove box, while the rear brackets are secured with
screws to the upper glove box opening reinforcement. A yellow connector on the end of a short,
two-wire pigtail harness connects the passenger airbag inflator to the vehicle electrical system.
The molded plastic passenger airbag door has a predetermined horizontal breakout line near its
center which is concealed beneath its decorative outer surface. Return flanges near the top and
bottom of the airbag door feature windows that are engaged on hook formations at the top and
bottom of the airbag housing. Three tabs extend downward from the lower return flange and are
secured with the same screws that secure the glove box module to the upper glove box opening
reinforcement. Five molded snap features along the top of the airbag door above the upper return
flange snap into receptacles located in the instrument panel base trim just below the instrument
panel top cover. Following a passenger airbag deployment, the passenger airbag and airbag door
unit must be replaced. The passenger airbag cannot be repaired, and must be replaced if faulty or
in any way damaged. The passenger airbag door is serviced only as a unit with the passenger
airbag.
The passenger airbag is deployed by an electrical signal generated by the Airbag Control Module
(ACM) through the passenger airbag line 1 and line 2 (or squib) circuits. The hybrid-type inflator
assembly includes a small canister of highly compressed argon gas. When the ACM sends the
proper electrical signal to the airbag inflator, the electrical energy generates enough heat to ignite
chemical pellets within the inflator. Once ignited, these chemical pellets burn rapidly and produce
the pressure necessary to rupture a containment disk in the argon gas canister. The inflator and
argon gas canister are sealed to the airbag cushion so that all of the released argon gas is directed
into the airbag cushion, causing the cushion to inflate. As the cushion inflates, the passenger
airbag door will split at the breakout line and the two halves of the door will pivot out of the way.
Following an airbag deployment, the airbag cushion quickly deflates by venting the argon gas
through vents on the instrument panel side of the airbag cushion.
Some of the chemicals used to create the pressure to burst the argon gas containment disk are
considered hazardous in their solid state, before they are burned, but they are securely sealed
within the airbag inflator. However, the gas that is produced when the chemicals are burned is
harmless. A small amount of residue from the burned chemicals may cause some temporary
discomfort if it contacts the skin, eyes, or breathing passages. If skin or eye irritation is noticed,
rinse the affected area with plenty of cool, clean water. If breathing passages are irritated, move to
another area where there is plenty of clean, fresh air to breath. If the irritation is not alleviated by
these actions, contact a physician immediately.

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) is secured with screws to a mount welded onto the top of the
floor panel transmission tunnel behind the instrument panel center support bracket in the
passenger compartment of the vehicle. The ACM contains an electronic microprocessor, an
electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor.
The ACM is connected to the vehicle electrical system through a take out and connector of the
instrument panel wire harness.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the ACM contains the airbag system logic circuits, and it monitors and
controls all of the airbag system components. The ACM also uses On-Board Diagnostics (OBD)
and can communicate with other electronic modules in the vehicle as well as with the DRB III scan
tool using the Programmable Communications Interface (PCI) data bus network. This method of
communication is used for control of the airbag indicator in the ElectroMechanical Instrument
Cluster (EMIC) and for airbag system diagnosis and testing through the 16-way data link connector
located on the lower left edge of the instrument panel. (Refer to INSTRUMENT CLUSTER/AIRBAG
INDICATOR - OPERATION). The ACM microprocessor continuously monitors all of the airbag
system electrical circuits to determine the system readiness. If the ACM detects a monitored
system fault, it sets an active Diagnostic Trouble Code (DTC) and sends messages to the EMIC
over the PCI data bus to turn ON the airbag indicator. If the airbag system fault is still present when
the ignition switch is turned to the OFF position, the DTC is stored in memory by the ACM.
However, if a fault does not recur for a number of ignition cycles, the ACM will automatically erase
the stored DTC.
The ACM receives battery current through two circuits, on a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and on a fused ignition switch output (run-start) circuit
through a second fuse in the JB. The ACM is grounded through a ground circuit and take out of the
instrument panel wire harness. This take out has a single eyelet terminal connector secured by a
ground screw to the left side of the floor panel transmission tunnel near the ACM in the passenger
compartment. Therefore, the ACM is operational whenever the ignition switch is in the Start or ON
positions. The ACM also contains an energy-storage capacitor. When the ignition switch is in the
Start or ON positions, this capacitor is continually being charged with enough electrical energy to
deploy the airbags for up to one second following a battery disconnect or failure. The purpose of
the capacitor is to provide backup airbag system protection in case there is a loss of battery current
supply to the ACM during an impact. The capacitor is only serviced as a unit with the ACM.
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensor is an accelerometer that senses the rate of vehicle deceleration, which
provides verification of the direction and severity of an impact. A pre-programmed decision
algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the
impact sensor indicates an impact that is severe enough to require airbag system protection. When
the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags and
the seat belt tensioners. The safing sensor is an electromechanical sensor within the ACM that is
connected in series between the ACM microprocessor deployment circuit and the airbags/seat belt
tensioners. The safing sensor is a normally open switch that is used to verify or confirm the need
for an airbag deployment by detecting impact energy of a lesser magnitude than that of the
electronic impact sensor, and must be closed in order for the airbags/seat belt tensioners to deploy.
The impact sensor and safing sensor are calibrated for the specific vehicle, and are only serviced
as a unit with the ACM.

DISCUSSION:
Airbag
When servicing any airbag system, it is essential to follow the proper Service Manual and/or
Diagnostic Manual procedures for diagnosing, testing, and replacing of any component. When
diagnosing any airbag squib circuit Diagnostic Trouble Code (DTC) with a DRBIII(R), the use of the
Airbag Load Tool (Special Tool 8310 and 8443) is required. The Airbag Load Tool, used in
conjunction with the DRBIII(R) are used to isolate and test components and wiring for failure. Only
replace the component or wiring that has failed. This will reduce unnecessary cost to the customer
or DaimlerChrysler.
NOTE:
AIRBAG REPLACEMENT IS NOT REQUIRED EVERY TIME IT IS REMOVED OR WHEN
ANOTHER COMPONENT HAS FAILED. USE OF THE DRBIII(R) AND AIRBAG LOAD TOOL
WILL DETERMINE IF THE AIRBAG HAS FAILED AND REPLACEMENT IS NEEDED.

Clock Springs
Recent analysis of returned clock springs have indicated that prior service may have contributed to
the clock spring's failure.
^ Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often
used in the clock spring area of the steering column to eliminate noise. Lubricants may have an
adverse effect on the clock spring.
^ Clock spring centering. Any repair that may disrupt the positioning of the steering wheel with the
front wheels will require that the clock spring be centered. This includes clock spring replacement,
steering column service, HVAC service, steering gear service, and front suspension crossmember
service. Refer to the appropriate Service Manual for the clock spring centering procedure.

Clockspring Assembly / Spiral Cable: Description and Operation
Fig. 7 Clockspring And Multi-Function Switch
The clockspring assembly is secured with two screws onto the multi-function switch mounting
housing near the top of the steering column behind the steering wheel. The clockspring consists of
a flat, round molded plastic case with a stubby tail that hangs below the steering column and
contains two connector receptacles that face toward the instrument panel. Within the plastic
housing is a spool-like molded plastic rotor with a large exposed hub. The upper surface of the
rotor hub has a large center hole, two large flats, an engagement dowel with a yellow rubber boot,
a short pigtail wire with connector, and two connector receptacles that face toward the steering
wheel. The lower surface of the rotor hub has a molded plastic turn signal cancel cam with two
lobes that is keyed to the rotor and is secured there with four integral snap features. Within the
plastic case and wound around the rotor spool is a long ribbon-like tape that consists of several thin
copper wire leads sandwiched between two thin plastic membranes. The outer end of the tape
terminates at the connector receptacles that face the instrument panel, while the inner end of the
tape terminates at the pigtail wire and connector receptacles on the hub of the clockspring rotor
that face the steering wheel.
Service replacement clocksprings are shipped pre-centered and with a locking pin that snaps into a
receptacle on the rotor and is engaged between two tabs on the upper surface of the rotor case.
The locking pin secures the centered clockspring rotor to the clockspring case during shipment, but
the locking pin must be removed from the clockspring after it is installed on the steering column.
(Refer to CLOCKSPRING - STANDARD PROCEDURE - CLOCKSPRING CENTERING).
The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
The clockspring is a mechanical electrical circuit component that is used to provide continuous
electrical continuity between the fixed instrument panel wire harness and the electrical components
mounted on or in the rotating steering wheel. On this model the rotating electrical components
include the driver airbag, the horn switch, the speed control switches, and the remote radio
switches if the vehicle is so equipped. The clockspring case is positioned and secured to the
multi-function switch mounting housing near the top of the steering column. The connector
receptacles on the tail of the fixed clockspring case connect the clockspring to the vehicle electrical
system through two take outs with connectors from the instrument panel wire harness. The
clockspring rotor is movable and is keyed by an engagement dowel that is molded onto the rotor
hub between two fins that are cast into the lower surface of the steering wheel armature. A yellow
rubber boot is installed over the engagement dowel to eliminate noise. The two lobes on the turn
signal cancel cam on the lower surface of the clockspring rotor hub contact a turn signal cancel
actuator of the multi-function switch to provide automatic turn signal cancellation. The yellow
sleeved pigtail wires on the upper surface of the clockspring rotor connect the clockspring to the
driver airbag, while a steering wheel wire harness connects the two connector receptacles on the
upper surface of the clockspring rotor to the horn switch and, if the vehicle is so equipped, to the
optional speed control and remote radio switches on the steering wheel.
Like the clockspring in a timepiece, the clockspring tape has travel limits and can be damaged by
being wound too tightly during full stop-to-stop steering wheel rotation. To prevent this from
occurring, the clockspring is centered when it is installed on the steering column. Centering the
clockspring indexes the clockspring tape to the movable steering components so that the tape can
operate within its designed travel limits. However, if the clockspring is removed from the steering
column or if the steering shaft is disconnected from the steering gear, the clockspring spool can
change position

relative to the movable steering components and must be re-centered following completion of the
service or the tape may be damaged. Service replacement clocksprings are shipped pre-centered
and with a plastic locking pin installed. This locking pin should not be disengaged until the
clockspring has been installed on the steering column. If the locking pin is removed or damaged
before the clockspring is installed on a steering column, the clockspring centering procedure must
be performed. (Refer to CLOCKSPRING - STANDARD PROCEDURE - CLOCKSPRING
CENTERING).

The clockspring is designed to wind and unwind when the steering wheel is rotated, but is only
designed to rotate the same number of turns (about five complete rotations) as the steering wheel
can be turned from stop to stop. Centering the clockspring indexes the clockspring tape to other
steering components so that it can operate within its designed travel limits. The rotor of a centered
clockspring can be rotated two and one-half turns in either direction from the centered position,
without damaging the clockspring tape.
Fig. 7 Clockspring And Multi-Function Switch
However, if the clockspring is removed for service or if the steering column is disconnected from
the steering gear, the clockspring tape can change position relative to the other steering
components. The clockspring must then be re-centered following completion of such service or the
clockspring tape may be damaged. Service replacement clocksprings are shipped pre-centered
and with a plastic locking pin installed. This locking pin should not be removed until the clockspring
has been installed on the steering column. If the locking pin is removed before the clockspring is
installed on a steering column, the clockspring centering procedure must be performed.

Malfunction Lamp / Indicator: Description and Operation
AIRBAG INDICATOR
An airbag indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with airbags, this indicator is electronically disabled. The airbag indicator is located in the
Information Center area of the instrument cluster, to the right of center. The airbag indicator
consists of a stenciled cutout of the word "AIRBAG" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the
"AIRBAG" text to appear in red through the translucent outer layer of the overlay when it is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The airbag indicator is serviced as a unit with the instrument cluster.
The airbag indicator gives an indication to the vehicle operator when the airbag system is faulty or
inoperative. The airbag indicator is controlled by a transistor on the instrument cluster circuit board
based upon cluster programming and electronic messages received by the cluster from the Airbag
Control Module (ACM) over the Programmable Communications Interface (PCI) data bus. The
airbag indicator Light Emitting Diode (LED) receives battery current on the instrument cluster
electronic circuit board through the fused ignition switch output (run-start) circuit whenever the
ignition switch is in the ON or Start positions; therefore, the indicator will always be OFF when the
ignition switch is in any position except ON or Start. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn ON the airbag
indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the airbag indicator is
illuminated for about seven seconds. The first two seconds is the cluster bulb test function, and the
remainder is the ACM bulb test function.
- ACM Lamp-ON Message - Each time the cluster receives a lamp-ON message from the ACM, the
airbag indicator will be illuminated. The indicator remains illuminated for about twelve seconds or
until the cluster receives a lamp-OFF message from the ACM, whichever is longer.
- Communication Error - If the cluster receives no airbag messages for three consecutive seconds,
the airbag indicator is illuminated. The indicator remains illuminated for about twelve seconds or
until the cluster receives a single lamp-OFF message from the ACM, whichever is longer.
- Actuator Test - Each time the cluster is put through the actuator test, the airbag indicator will be
turned ON, then OFF again during the bulb check portion of the test to confirm the functionality of
the LED and the cluster control circuitry.
The ACM continually monitors the airbag system circuits and sensors to decide whether the system
is in good operating condition. The ACM then sends the proper lamp-ON or lamp-OFF messages
to the instrument cluster. If the ACM sends a lamp-ON message after the bulb test, it indicates that
the ACM has detected a system malfunction and/or that the airbags may not deploy when required,
or may deploy when not required. The ACM will store a Diagnostic Trouble Code (DTC) for any
malfunction it detects. Each time the airbag indicator fails to illuminate due to an open or short in
the cluster airbag indicator circuit, the cluster sends a message notifying the ACM of the condition.
The ACM will store a DTC and the cluster will begin blinking the seat belt indicator. (Refer to
SEATBELT INDICATOR - OPERATION). For proper diagnosis of the airbag system, the ACM, the
PCI data bus, or the message inputs to the instrument cluster that control the airbag indicator, a
DRB III scan tool is required. Refer to the appropriate diagnostic information.

Air Bag Control Module: Description and Operation
The Airbag Control Module (ACM) is secured with screws to a mount welded onto the top of the
floor panel transmission tunnel behind the instrument panel center support bracket in the
passenger compartment of the vehicle. The ACM contains an electronic microprocessor, an
electronic impact sensor, an electromechanical safing sensor, and an energy storage capacitor.
The ACM is connected to the vehicle electrical system through a take out and connector of the
instrument panel wire harness.
The ACM cannot be repaired or adjusted and, if damaged or faulty, it must be replaced.
The microprocessor in the ACM contains the airbag system logic circuits, and it monitors and
controls all of the airbag system components. The ACM also uses On-Board Diagnostics (OBD)
and can communicate with other electronic modules in the vehicle as well as with the DRB III scan
tool using the Programmable Communications Interface (PCI) data bus network. This method of
communication is used for control of the airbag indicator in the ElectroMechanical Instrument
Cluster (EMIC) and for airbag system diagnosis and testing through the 16-way data link connector
located on the lower left edge of the instrument panel. (Refer to INSTRUMENT CLUSTER/AIRBAG
INDICATOR - OPERATION). The ACM microprocessor continuously monitors all of the airbag
system electrical circuits to determine the system readiness. If the ACM detects a monitored
system fault, it sets an active Diagnostic Trouble Code (DTC) and sends messages to the EMIC
over the PCI data bus to turn ON the airbag indicator. If the airbag system fault is still present when
the ignition switch is turned to the OFF position, the DTC is stored in memory by the ACM.
However, if a fault does not recur for a number of ignition cycles, the ACM will automatically erase
the stored DTC.
The ACM receives battery current through two circuits, on a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and on a fused ignition switch output (run-start) circuit
through a second fuse in the JB. The ACM is grounded through a ground circuit and take out of the
instrument panel wire harness. This take out has a single eyelet terminal connector secured by a
ground screw to the left side of the floor panel transmission tunnel near the ACM in the passenger
compartment. Therefore, the ACM is operational whenever the ignition switch is in the Start or ON
positions. The ACM also contains an energy-storage capacitor. When the ignition switch is in the
Start or ON positions, this capacitor is continually being charged with enough electrical energy to
deploy the airbags for up to one second following a battery disconnect or failure. The purpose of
the capacitor is to provide backup airbag system protection in case there is a loss of battery current
supply to the ACM during an impact. The capacitor is only serviced as a unit with the ACM.
Two sensors are contained within the ACM, an electronic impact sensor and a safing sensor. The
electronic impact sensor is an accelerometer that senses the rate of vehicle deceleration, which
provides verification of the direction and severity of an impact. A pre-programmed decision
algorithm in the ACM microprocessor determines when the deceleration rate as signaled by the
impact sensor indicates an impact that is severe enough to require airbag system protection. When
the programmed conditions are met, the ACM sends an electrical signal to deploy the airbags and
the seat belt tensioners. The safing sensor is an electromechanical sensor within the ACM that is
connected in series between the ACM microprocessor deployment circuit and the airbags/seat belt
tensioners. The safing sensor is a normally open switch that is used to verify or confirm the need
for an airbag deployment by detecting impact energy of a lesser magnitude than that of the
electronic impact sensor, and must be closed in order for the airbags/seat belt tensioners to deploy.
The impact sensor and safing sensor are calibrated for the specific vehicle, and are only serviced
as a unit with the ACM.

WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING
FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN

Seat Belt Buckle Switch: Description and Operation
LUMBAR CONTROL SWITCH
The 8-way power seat option includes an electrically operated lumbar support mechanism. A single
two-way momentary power lumbar switch is integral with the power seat switches. The power
lumbar switch is secured to the back of the seat cushion side shield with screws, and the switch
paddle protrudes through a hole to the outside of the shield. The switch paddle is located in a
shallow depression molded into the outer surface of the seat cushion side shield that helps to
shroud it from unintentional actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or repaired and, if faulty or damaged, the seat
switch assembly must be replaced.
When the power lumbar switch paddle is actuated, a battery feed and a ground path are applied
through the switch contacts to the power lumbar adjuster motor. The motor operates to move the
lumbar adjuster through its drive unit in the selected direction until the switch is released, or until
the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the
battery feed and ground path to the motor are reversed through the switch contacts. This causes
the motor to run in the opposite direction.
The power lumbar switch should not be held applied in either direction after the adjuster has
reached its travel limit. The power lumbar adjuster motor contains a self-resetting circuit breaker to
protect it from overload. However, consecutive or frequent resetting of the circuit breaker must not
be allowed to continue, or the motor may be damaged.
SEAT BELT SWITCH
The seat belt switch is a small, normally open, single pole, single throw, plunger actuated,
momentary switch. Only one seat belt switch is installed in the vehicle, and it is integral to the driver
seat belt retractor assembly. The seat belt switch is connected to the vehicle electrical system
through a short pigtail wire to a dedicated take out and connector of the body wire harness.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver seat
belt and retractor unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the Electro-Mechanical Instrument Cluster (EMIC). The seat belt switch plunger is actuated by the
seat belt webbing wound onto the seat belt retractor spool. When the seat belt tip-half webbing is
pulled out of the retractor far enough to engage the seat belt buckle-half, the switch plunger is
extended and closes the seat belt switch sense circuit to ground; and, when the seat belt tip-half
webbing is wound onto the retractor the switch plunger is depressed, opening the ground path. The
EMIC monitors the seat belt switch status, then controls the seatbelt indicator and sends electronic
chime request messages over the Programmable Communications Interface (PCI) data bus to the
Central Timer Module (CTM) based upon that input.
The seat belt switch receives ground through its pigtail wire connection to the body wire harness
from another take out of the body wire harness. An eyelet terminal connector on that ground take
out is secured under a ground screw to the left lower B-pillar. The seat belt switch is connected in
series between ground and the seat belt switch sense input of the EMIC.

1. Disconnect and isolate the battery negative cable. Disconnect the body wire harness connector
for the seat belt switch from the seat belt switch
pigtail wire connector from the driver side front seat belt retractor. Check for continuity between the
ground circuit cavity of the body wire harness connector for the seat belt switch and a good ground.
There should be continuity. If OK, go to Step 2. If not OK, repair the open ground circuit to ground
(G307) as required.
2. Check for continuity between the two cavities in the seat belt switch pigtail wire connector. There
should be no continuity with the seat belt
webbing retracted, and continuity with the seat belt webbing pulled out of the retractor far enough
to engage the seat belt buckle. If OK, go to Step 3 .If not OK, replace the faulty driver side front
seat belt and retractor unit.
3. Remove the instrument cluster from the instrument panel. Check for continuity between the seat
belt switch sense circuit cavity of the body wire
harness connector for the seat belt switch and a good ground. There should be no continuity. If OK,
go to Step 4. If not OK, repair the shorted seat belt switch sense circuit between the seat belt
switch and the instrument cluster as required.
4. Check for continuity between the seat belt switch sense circuit cavities of the instrument panel
wire harness connector (Connector C2) for the
instrument cluster and the body wire harness connector for the seat belt switch. There should be
continuity. If OK, proceed to the diagnosis for the instrument cluster. (Refer to INSTRUMENT

Seat Belt Reminder Lamp: Description and Operation
A seatbelt indicator is standard equipment on all instrument clusters. The seatbelt indicator is
located in the Information Center area of the instrument cluster, to the right of center. The seatbelt
indicator consists of a stencilled cutout of the International Control and Display Symbol icon for
"Seat Belt" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red lens behind the
cutout in the opaque layer of the overlay causes the icon to appear in red through the translucent
outer layer of the overlay when the indicator is illuminated from behind by a Light Emitting Diode
(LED) soldered onto the instrument cluster electronic circuit board. The seatbelt indicator is
serviced as a unit with the instrument cluster.
The seatbelt indicator gives an indication to the vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and a hard wired input from the seatbelt switch in the driver side front
seatbelt retractor through the seat belt indicator driver circuit. The seatbelt indicator Light Emitting
Diode (LED) receives battery current on the instrument cluster electronic circuit board through the
fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions; therefore, the indicator will always be OFF when the ignition switch is in any position
except ON or Start. The LED only illuminates when it is switched to ground by the instrument
cluster transistor. The instrument cluster will turn ON the seatbelt indicator for the following
reasons:
- Seatbelt Reminder Function - Each time the cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indicator will be illuminated as a seatbelt reminder for
about seven seconds, or until the ignition switch is turned to the OFF position, whichever occurs
first. This reminder function will occur regardless of the status of the seatbelt switch input to the
cluster.
- Driver Side Front Seatbelt Not Buckled - Following the seatbelt reminder function, each time the
cluster detects an open circuit on the seat belt indicator driver circuit (seatbelt switch open - seatbelt unbuckled) with the ignition switch in the Start or ON positions, the indicator will be illuminated.
The seatbelt indicator remains illuminated until the seat belt indicator driver input to the cluster is
closed to ground (seatbelt switch closed - seatbelt buckled), or until the ignition switch is turned to
the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The seatbelt switch input to the instrument cluster circuitry can be diagnosed using conventional
diagnostic tools and methods. For further diagnosis of the seatbelt indicator or the instrument
cluster circuitry that controls the LED, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND
TESTING).

Seat Belt Tensioner: Description and Operation
Seat belt tensioners supplement the airbag system for this model. The seat belt tensioners are
integral to the front seat belt retractors, which are secured within each B-pillar in the vehicle where
they are concealed behind the B-pillar trim. The seat belt tensioner consists primarily of a
sprocket/pinion, a steel tube, a cast metal housing, numerous steel balls, a stamped metal ball
trap, a torsion bar, a small pyrotechnically activated gas generator, and a short pigtail wire. All of
these components are located on one side of the retractor spool on the outside of the retractor
housing except for the torsion bar, which serves as the spindle upon which the retractor spool
rides. The seat belt tensioners are controlled by the Airbag Control Module (ACM) and are
connected to the vehicle electrical system through a dedicated take out of the body wire harness by
a keyed and latching molded plastic connector insulator to ensure a secure connection.
The seat belt tensioners cannot be repaired and, if faulty or damaged, the entire front seat belt,
retractor, and tensioner unit must be replaced. The seat belt tensioners are not intended for reuse,
and both tensioners must be replaced following any airbag deployment. A growling or grinding
sound while attempting to operate the seat belt retractor is a sure indication that the seat belt
tensioner has been deployed and requires replacement. For seat belt tensioner service procedures,
(Refer to FRONT SEAT BELT & RETRACTOR - REMOVAL).
The seat belt tensioners are deployed in conjunction with the airbags by a signal generated by the
Airbag Control Module (ACM) through the driver or passenger seat belt tensioner line 1 and line 2
(or squib) circuits. When the ACM sends the proper electrical signal to the tensioner, the electrical
energy generates enough heat to initiate a small pyrotechnic gas generator. The gas generator is
installed in one end of a steel tube that contains numerous steel balls. As the gas expands, it
pushes the steel balls through the tube into a cast metal housing, where a ball guide directs the
balls into engagement with the teeth of a sprocket that is geared to one end of the retractor spool.
As the balls drive past the sprocket, the sprocket turns and drives the seat belt retractor spool
causing the slack to be removed from the front seat belts. The ball trap captures the balls as they
leave the sprocket and are expelled from the housing. Removing excess slack from the front seat
belts not only keeps the occupants properly positioned for an airbag deployment following a frontal
impact of the vehicle, but also helps to reduce the likelihood of a harmful contact with interior
components. Also, the seat belt tensioner torsion bar that the retractor spool rides upon is designed
to deform in order to control the loading being applied to the occupants by the seat belts during a
frontal impact, further reducing the potential for occupant injuries.
The ACM monitors the condition of the seat belt tensioners through circuit resistance, and will
illuminate the airbag indicator in the instrument cluster and store a Diagnostic Trouble Code (DTC)
for any fault that is detected. For proper diagnosis of the seat belt tensioners, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.

Seat Belt Buckle Switch: Description and Operation
LUMBAR CONTROL SWITCH
The 8-way power seat option includes an electrically operated lumbar support mechanism. A single
two-way momentary power lumbar switch is integral with the power seat switches. The power
lumbar switch is secured to the back of the seat cushion side shield with screws, and the switch
paddle protrudes through a hole to the outside of the shield. The switch paddle is located in a
shallow depression molded into the outer surface of the seat cushion side shield that helps to
shroud it from unintentional actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or repaired and, if faulty or damaged, the seat
switch assembly must be replaced.
When the power lumbar switch paddle is actuated, a battery feed and a ground path are applied
through the switch contacts to the power lumbar adjuster motor. The motor operates to move the
lumbar adjuster through its drive unit in the selected direction until the switch is released, or until
the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the
battery feed and ground path to the motor are reversed through the switch contacts. This causes
the motor to run in the opposite direction.
The power lumbar switch should not be held applied in either direction after the adjuster has
reached its travel limit. The power lumbar adjuster motor contains a self-resetting circuit breaker to
protect it from overload. However, consecutive or frequent resetting of the circuit breaker must not
be allowed to continue, or the motor may be damaged.
SEAT BELT SWITCH
The seat belt switch is a small, normally open, single pole, single throw, plunger actuated,
momentary switch. Only one seat belt switch is installed in the vehicle, and it is integral to the driver
seat belt retractor assembly. The seat belt switch is connected to the vehicle electrical system
through a short pigtail wire to a dedicated take out and connector of the body wire harness.
The seat belt switch cannot be adjusted or repaired and, if faulty or damaged, the entire driver seat
belt and retractor unit must be replaced.
The seat belt switch is designed to control a path to ground for the seat belt switch sense input of
the Electro-Mechanical Instrument Cluster (EMIC). The seat belt switch plunger is actuated by the
seat belt webbing wound onto the seat belt retractor spool. When the seat belt tip-half webbing is
pulled out of the retractor far enough to engage the seat belt buckle-half, the switch plunger is
extended and closes the seat belt switch sense circuit to ground; and, when the seat belt tip-half
webbing is wound onto the retractor the switch plunger is depressed, opening the ground path. The
EMIC monitors the seat belt switch status, then controls the seatbelt indicator and sends electronic
chime request messages over the Programmable Communications Interface (PCI) data bus to the
Central Timer Module (CTM) based upon that input.
The seat belt switch receives ground through its pigtail wire connection to the body wire harness
from another take out of the body wire harness. An eyelet terminal connector on that ground take
out is secured under a ground screw to the left lower B-pillar. The seat belt switch is connected in
series between ground and the seat belt switch sense input of the EMIC.

Antenna Cable: Description and Operation
ANTENNA BODY & CABLE
All models use a black painted fixed-length stainless steel rod-type antenna mast, installed on the
right front fender of the vehicle. The antenna mast has a spiral groove cut down its length to reduce
wind noise. The antenna mast is connected to the center wire of the coaxial antenna cable, and is
not grounded to any part of the vehicle. To eliminate static, the antenna base must have a good
ground. The coaxial antenna cable shield (the outer wire mesh of the cable) is grounded to the
antenna base and the radio receiver chassis.
The antenna coaxial cable has an additional disconnect, located near the outboard side of the
glove box opening on the back side of the lower instrument panel reinforcement. This additional
disconnect allows the instrument panel assembly to be removed and installed without removing the
radio receiver.
The factory-installed Electronically Tuned Radios (ETR) automatically compensate for radio
antenna trim. Therefore, no antenna trimmer adjustment is required or possible when replacing the
radio receiver or the antenna.

The following four tests are used to diagnose the antenna with an ohmmeter:
- Test 1 - Mast to ground test
- Test 2 - Tip-of-mast to tip-of-conductor test
- Test 3 - Body ground to battery ground test
- Test 4 - Body ground to coaxial shield test.
Antenna Tests
The ohmmeter test lead connections for each test are shown in Antenna Tests.
NOTE:
- This model has a special coating on the antenna mast which is not electrically conductive.
Remove the antenna mast from the antenna base before attempting to perform Tests 1 and 2.
- This model has a two-piece antenna coaxial cable. Tests 2 and 4 must be conducted in two steps
to isolate a coaxial cable problem; from the coaxial cable connection under the right end of the
instrument panel near the outboard side of the glove box opening to the antenna base, and then
from the coaxial cable connection to the radio chassis connection.
TEST 1 Test 1 determines if the antenna mast is insulated from the base. Proceed as follows: 1.
Disconnect the antenna coaxial cable connector from the radio receiver chassis and isolate.
Remove the antenna mast from the antenna base. 2. Insert one ohmmeter test lead into the socket
for the antenna mast in the center of the antenna base. Connect the other test lead to the perimeter
of
the antenna base. Check for continuity.
3. There should be no continuity. If continuity is found, replace the faulty or damaged antenna base
and cable assembly.
TEST 2 Test 2 checks the antenna for an open circuit as follows: 1. Disconnect the antenna coaxial
cable connector from the radio receiver chassis. Remove the antenna mast from the antenna base.
2. Insert one ohmmeter test lead into the socket for the antenna mast in the center of the antenna
base. Connect the other test lead to the center pin of
the antenna coaxial cable connector.
3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite
resistance indicates damage to the base and
cable assembly. Replace the faulty base and cable, if required.
TEST 3 Test 3 checks the condition of the vehicle body ground connection. This test should be
performed with the battery positive cable removed from the battery. Disconnect both battery cables,
the negative cable first. Reconnect the battery negative cable and perform the test as follows: 1.
Connect one ohmmeter test lead to the vehicle fender. Connect the other test lead to the battery
negative terminal post. 2. The resistance should be less than one ohm. 3. If the resistance is more
than one ohm, check the braided ground strap(s) connected to the engine and the vehicle body for
being loose, corroded,
or damaged. Repair the ground strap connections, if required.
TEST 4 Test 4 checks the condition of the ground between the antenna base and the vehicle body
as follows:

Fig.10 Sentry Key Immobilizer Module
SENTRY KEY IMMOBILIZER MODULE
The Sentry Key Immobilizer Module (SKIM) is the primary component of the Sentry Key
Immobilizer System (SKIS). The SKIM is located on the right side of the steering column, below the
ignition lock cylinder housing and is concealed beneath the steering column shrouds. The molded
black plastic housing for the SKIM has an integral molded plastic halo-like antenna ring that
extends from one end. When the SKIM is properly installed on the steering column, the antenna
ring is oriented around the circumference of the ignition lock cylinder housing. A single integral
connector receptacle containing six terminal pins is located on the opposite end of the SKIM
housing from the antenna ring. A stamped metal mounting bracket secured to the SKIM housing
has a U-shaped clip formation that is used to secure the unit to the right lower flange of the steering
column jacket.
The SKIM cannot be adjusted or repaired. If faulty or damaged, the entire SKIM unit must be
replaced.
The Sentry Key Immobilizer Module (SKIM) contains a Radio Frequency (RF) transceiver and a
microprocessor. The SKIM transmits RF signals to, and receives RF signals from the Sentry Key
transponder through a tuned antenna enclosed within the molded plastic antenna ring integral to
the SKIM housing. If this antenna ring is not mounted properly around the ignition lock cylinder
housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM), the Electro Mechanical Instrument Cluster (EMIC) and/or the
DRB III scan tool.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM, and is encoded to the transponder of every
Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the Sentry Key Immobilizer System (SKIS). Another
security code, called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM during SKIS
initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using the DRB III® scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The DRB III scan tool
will alert the technician during the SKIS initialization procedure if new Sentry Keys are required.
When the ignition switch is turned to the ON position, the SKIM transmits an RF signal to the
transponder in the ignition key. The SKIM then waits for an RF signal response from the
transponder. If the response received identifies the key as valid, the SKIM sends a valid key
message to the PCM over the PCI data bus. If the response received identifies the key as invalid,
or if no response is received from the key transponder, the SKIM sends an invalid key message to
the PCM. The PCM will enable or disable engine operation based upon the status of the SKIM
messages. It is important to note that the default condition in the PCM is an invalid key; therefore, if
no message is received from the SKIM by the PCM, the engine will be disabled and the vehicle
immobilized after two seconds of running.

The SKIM also sends SKIS indicator status messages to the EMIC over the PCI data bus to tell the
EMIC how to operate the SKIS indicator. This indicator status message tells the EMIC to turn the
indicator ON for about three seconds each time the ignition switch is turned to the ON position as a
bulb test. After completion of the bulb test, the SKIM sends indicator status messages to the EMIC
to turn the indicator off, turn the indicator ON, or to flash the indicator ON and OFF. If the SKIS
indicator flashes or stays ON solid after the bulb test, it signifies a SKIS fault. If the SKIM detects a
system malfunction and/or the SKIS has become inoperative, the SKIS indicator will stay ON solid.
If the SKIM detects an invalid key or if a key transponder-related fault exists, the SKIS indicator will
flash. If the vehicle is equipped with the Customer Learn transponder programming feature, the
SKIM will also send messages to the EMIC to flash the SKIS indicator and to generate a single
audible chime tone whenever the Customer Learn programming mode is being utilized. (Refer to
VEHICLE THEFT SECURITY - STANDARD PROCEDURE - SENTRY KEY TRANSPONDER
PROGRAMMING).
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will
store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM memory if a system
malfunction is detected. The SKIM can be diagnosed, and any stored DTC's can be retrieved using
a DRB III scan tool. Refer to the appropriate diagnostic information.

Alarm System Transponder: Description and Operation
Sentry Key Immobilizer Transponder
TRANSPONDER KEY
Each ignition key used in the Sentry Key Immobilizer System (SKIS) has an integral transponder
chip. Ignition keys with this feature can be readily identified by a gray rubber cap molded onto the
head of the key, while conventional ignition keys have a black molded rubber cap. The transponder
chip is concealed beneath the molded rubber cap, where it is molded within a plastic mount into the
head of the metal key. In addition to being cut to match the mechanical coding of the ignition lock
cylinder, each new Sentry Key has a unique transponder identification code permanently
programmed into it by the manufacturer. The Sentry Key transponder cannot be adjusted or
repaired. If faulty or damaged, the entire key must be replaced.
When the ignition switch is turned to the ON position, the Sentry Key Immobilizer Module (SKIM)
communicates through its antenna with the Sentry Key transponder using a Radio Frequency (RF)
signal. The SKIM then listens for a RF response from the transponder through the same antenna.
The Sentry Key transponder chip is within the range of the SKIM transceiver antenna ring when it is
inserted into the ignition lock cylinder. The SKIM determines whether a valid key is present in the
ignition lock cylinder based upon the response from the transponder. If a valid key is detected, that
fact is communicated by the SKIM to the Powertrain Control Module (PCM) over the Programmable
Communications Interface (PCI) data bus, and the PCM allows the engine to continue running. If
the PCM receives an invalid key message, or receives no message from the SKIM over the PCI
data bus, the engine will be disabled after about two seconds of operation. The ElectroMechanical
Instrument Cluster (EMIC) will also respond to the invalid key message on the PCI data bus by
flashing the security indicator ON and OFF.
Each Sentry Key has a unique transponder identification code permanently programmed into it by
the manufacturer. Likewise, the SKIM has a unique Secret Key code programmed into it by the
manufacturer. When a Sentry Key is programmed into the memory of the SKIM, the SKIM stores
the transponder identification code from the Sentry Key, and the Sentry Key learns the Secret Key
code from the SKIM. Once the Sentry Key learns the Secret Key code of the SKIM, it is
permanently stored in the memory of the transponder. Therefore, once a Sentry Key has been
programmed to a particular vehicle, it cannot be used on any other vehicle. (Refer to VEHICLE
THEFT SECURITY - STANDARD PROCEDURE - TRANSPONDER PROGRAMMING).
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will
store key-related fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM
memory if a Sentry Key transponder problem is detected. The Sentry Key transponder chip can be
diagnosed, and any stored DTC's can be retrieved using a DRB III scan tool. Refer to the
appropriate diagnostic information.

Alarm System Transponder: Service and Repair
All Sentry Keys included with the vehicle are preprogrammed to work with the Sentry Key
Immobilizer System (SKIS) when it is shipped from the factory. The Sentry Key Immobilizer Module
(SKIM) can be programmed to recognize up to a total of eight Sentry Keys. When programming a
blank Sentry Key transponder, the key must first be cut to match the ignition switch lock cylinder in
the vehicle for which it will be used. Once the additional or new key has been cut, the SKIM must
be programmed to recognize it as a valid key. There are two possible methods to program the
SKIM to recognize a new or additional valid key, the Secured Access Method and the Customer
Learn Method. Following are the details of these two programming methods.
Secured Access Method
The Secured Access method applies to all vehicles. This method requires the use of a DRB III scan
tool. This method will also require that you have access to the unique four-digit PIN code that was
assigned to the original SKIM. The PIN code must be used to enter the Secured Access Mode in
the SKIM. This PIN number may be obtained from the vehicle owner, from the original vehicle
invoice, or from the DaimlerChrysler Customer Center. Refer to the appropriate diagnostic
information for the proper Secured Access method programming procedures.
Customer Learn Method
The Customer Learn feature is only available on domestic vehicles, or those vehicles which have a
U.S. country code designator. This programming method also requires access to at least two valid
Sentry Keys. If two valid Sentry Keys are not available, or if the vehicle does not have a U.S.
country code designator, the Secured Access Method must be used to program new or additional
valid keys to the SKIM. The Customer Learn programming method procedures are as follows:
1. Obtain the blank Sentry Key(s) that are to be programmed as valid keys for the vehicle. Cut the
blank key(s) to match the ignition switch lock
cylinder mechanical key codes.
2. Insert one of the two valid Sentry Keys into the ignition switch and turn the ignition switch to the
ON position. 3. After the ignition switch has been in the ON position for longer than three seconds,
but no more than fifteen seconds, cycle the ignition switch
back to the OFF position. Replace the first valid Sentry Key in the ignition switch lock cylinder with
the second valid Sentry Key and turn the ignition switch back to the ON position. The second valid
Sentry Key must be inserted in the lock cylinder within fifteen seconds of removing the first valid
key.
4. About ten seconds after the completion of Step 3, the security indicator in the instrument cluster
will start to flash to indicate that the system has
entered the Customer Learn programming mode.
5. Within sixty seconds of entering the Customer Learn programming mode, turn the ignition switch
to the OFF position, replace the valid Sentry
Key with a blank Sentry Key transponder, and turn the ignition switch back to the ON position.
6. About ten seconds after the completion of Step 5, the security indicator will stop flashing, stay on
solid for three seconds, then turn OFF to
indicate that the blank Sentry Key has been successfully programmed. The SKIS will immediately
exit the Customer Learn programming mode and the vehicle may now be started using the newly
programmed valid Sentry Key
Each of these steps must be repeated and completed in their entirety for each additional Sentry
Key that is to be programmed. If the above steps are not completed in the given sequence, or
within the allotted time, the SKIS will exit the Customer Learn programming mode and the
programming will be unsuccessful. The SKIS will also automatically exit the Customer Learn
programming mode if it sees a non-blank Sentry Key transponder when it should see a blank, if it
has already programmed eight (8) valid Sentry Keys, or if the ignition switch is turned to the OFF
position for more than about fifty seconds.
NOTE: If an attempt is made to start the vehicle while in the Customer Learn mode (security indicator
flashing), the SKIS will respond as though the vehicle were being started with an invalid key. In
other words, the engine will stall after about two seconds of operation. No faults will be set.
- Once a Sentry Key has been programmed as a valid key to a vehicle, it cannot be programmed
as a valid key for use on any other vehicle.

Lock Cylinder Switch: Description and Operation
DOOR CYLINDER LOCK SWITCH
A door cylinder lock switch is snapped onto the back of the key lock cylinder inside each front door.
The door cylinder lock switch is a resistor multiplexed momentary switch that is hard wired in series
between a body ground and the Central Timer Module (CTM) through the front door wire harness.
The door cylinder lock switches are driven by the key lock cylinders and contain three internal
resistors. One resistor is used for the neutral switch position, one for the Lock position, and one for
the Unlock position.
The door cylinder lock switches cannot be adjusted or repaired and, if faulty or damaged, they must
be replaced.
The door cylinder lock switches are actuated by the key lock cylinder when the key is inserted in
the lock cylinder and turned to the lock or unlock positions. The door cylinder lock switch closes a
path to ground through one of three internal resistors for the Central Timer Module (CTM) when the
front door key lock cylinder is in the Lock, Unlock, or Neutral positions. The CTM reads the switch
status through an internal pull-up, then uses this information as an input for both power lock system
and Vehicle Theft Security System (VTSS) operation.
The door cylinder lock switches and circuits can be diagnosed using conventional diagnostic tools
and methods.
LIFTGATE CYLINDER LOCK SWITCH
The liftgate cylinder lock switch is snapped onto the back of the liftgate key lock cylinder inside the
liftgate. The liftgate cylinder lock switch is a resistor multiplexed momentary switch that is hard
wired in series between a body ground and the Central Timer Module (CTM) through the liftgate
wire harness. The liftgate cylinder lock switch is driven by the key lock cylinder and contains three
internal resistors. One resistor is used for the neutral switch position, one for the Lock position and
one for the Unlock position.
The liftgate cylinder lock switch cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The liftgate cylinder lock switch is actuated by the key lock cylinder when the key is inserted in the

The security indicator is located in the Information Center area of the instrument cluster, to the left
of center.

Dodge Workshop Manuals > Accessories and Optional Equipment > Antitheft and Alarm Systems > Security Lamp/Indicator
> Component Information > Locations > Page 6330
Security Lamp/Indicator: Description and Operation
A security indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional Vehicle Theft Security System (VTSS), this indicator is mechanically
disabled. The security indicator is located in the Information Center area of the instrument cluster,
to the left of center. The security indicator consists of a stenciled cutout of the word "SECURITY" in
the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not illuminated. A red lens behind the cutout in the
opaque layer of the overlay causes the "SECURITY" text to appear in red through the translucent
outer layer of the overlay when it is illuminated from behind by a Light Emitting Diode (LED)
soldered onto the instrument cluster electronic circuit board. The security indicator is serviced as a
unit with the instrument cluster.
The security indicator gives an indication to the vehicle operator when the Vehicle Theft Security
System (VTSS) is arming or is armed. On models equipped with the Sentry Key Immobilizer
System (SKIS), the security indicator also gives an indication to the vehicle operator of the status of
the SKIS. This indicator is controlled by a hard wired input to the instrument cluster from the
Central Timer Module (CTM) on the VTSS indicator driver circuit and, if the vehicle is so equipped,
by a transistor on the instrument cluster circuit board based upon electronic messages received by
the cluster from the Sentry Key Immobilizer Module (SKIM) over the Programmable
Communications Interface (PCI) data bus. The security indicator Light Emitting Diode (LED)
receives battery current on the instrument cluster electronic circuit board at all times through the
fused B(+) circuit at all times; therefore, the LED will remain functional regardless of the ignition
switch position. The LED only illuminates when it is provided a path to ground by the CTM or by the
instrument cluster transistor. The security indicator will be illuminated for the following reasons:
- Bulb Test - If the vehicle is equipped with SKIS, each time the ignition switch is turned to the ON
position the security indicator is illuminated by the instrument cluster for about three seconds based
upon an electronic lamp-ON message received from the SKIM as a bulb test. There is no bulb test
performed for models that are not equipped with the optional SKIS.
- VTSS Indication - During the seventeen second VTSS arming function, the CTM will flash the
security indicator ON and OFF repeatedly at a steady, fast rate to indicate that the VTSS is in the
process of arming. Following successful VTSS arming, the CTM flashes the security indicator ON
and OFF continuously at a slower rate to indicate that the VTSS is armed. The security indicator
continues flashing at the slower rate until the VTSS is disarmed or triggered. If the VTSS alarm is
triggered, the CTM will flash the security indicator at a steady, fast rate for up to eighteen minutes
or until the triggering condition is removed, before returning to the slower, armed flash rate.
- SKIM Lamp-ON Message - Each time the cluster receives a lamp-on message from the SKIM, the
security indicator will be illuminated. The indicator can be flashed ON and OFF, or illuminated solid,
as dictated by the SKIM message. The indicator remains illuminated solid or continues to flash until
the cluster receives a lamp-OFF message from the SKIM, or until the ignition switch is turned to the
OFF position, whichever occurs first. For more information on the SKIS and the security indicator
control parameters, (Refer to VEHICLE THEFT SECURITY/SENTRY KEY IMMOBILIZER
SYSTEM - OPERATION).
- Actuator Test - Each time the instrument cluster is put through the actuator test, the security
indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The CTM provides a hard wired ground input to the instrument cluster circuitry through the VTSS
indicator driver circuit whenever the ignition switch is in the OFF position and the VTSS is arming,
armed, or triggered. Whenever the ignition switch is in the ON or Start positions, the SKIM
performs a self-test to decide whether the system is in good operating condition. The SKIM then
sends the proper lamp-ON or lamp-OFF messages to the instrument cluster. For further diagnosis
of the security indicator or the instrument cluster circuitry that controls the indicator, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). If the SKIS turns ON the security
indicator after the bulb test, either solid or flashing, it indicates that a SKIS malfunction has
occurred or that the SKIS is inoperative. The VTSS indicator driver circuit input to the instrument
cluster can be diagnosed using conventional diagnostic tools and methods. For proper diagnosis of
the VTSS, the CTM, the SKIS, the PCI data bus, or the message inputs to the instrument cluster
that control the security indicator, a DRB III scan tool is required. Refer to the appropriate
diagnostic information.

Driver/Vehicle Information Display: Description and Operation
OVERHEAD CONSOLE
An overhead console unit is an available factory-installed option on this model The overhead
console unit features a garage door opener storage bin, a sunglasses storage bin, two reading and
courtesy lamps and either a standard paperclip or an optional compass mini-trip computer. See the
owner's manual in the vehicle glove box for more information on the features, use and operation of
all of the overhead console components and systems.
The overhead console for this model includes two front-mounted reading and courtesy lamps, a
sunglasses storage bin, universal transmitter and either a standard paperclip or an optional
compass mini-trip computer.
The overhead console is secured with two snap clips at the rear and a single screw at the front to
the overhead console mounting bracket. The front of the overhead console mounting bracket is
secured to the roof header near the windshield with two screws, and the rear of the bracket is
secured with double-faced tape to the inside surface of the roof panel. A single electrical
connection joins the overhead console wire harness to the roof wire harness.
Following are general descriptions of the major components used in the overhead console. See the
owner's manual in the vehicle glove box for more information on the use and operation of the
various overhead console features.
Sunglass Storage Bin
A sunglasses storage bin is included in the overhead console. The storage bin is located near the
center of the overhead console and is held in the closed position by a spring-loaded latch
mechanism that is integral to the storage bin door. The interior of the bin is lined with a foam rubber
padding material to protect the sunglasses from being scratched. A damper spring is snapped onto
the pivot shaft of the sunglasses storage bin door. The damper spring engages two flats on the
shaft and is anchored in a slot in the rear flange of the overhead console reading and courtesy
lamp housing to provide a smooth opening action and an open detent position for the storage bin
unit.
The sunglasses storage bin and door unit is available for service replacement. The bin and door
unit includes the spring-loaded latch mechanism, the bin liner and the damper spring. If any of
these components is damaged or faulty, the sunglasses storage bin and door unit must be
replaced.
The sunglasses storage bin is opened by pressing the latch on the rear edge of the door towards
the front of the vehicle, then pulling the bin downward to the open detent position. The
spring4oaded latch mechanism on the sunglasses bin door will automatically engage when the bin
is closed. See the owner's manual in the vehicle glove box for more information on the use and
operation of the sunglasses storage bin.
Paperclip
A paperclip is standard equipment on the base version of the overhead console. The paperclip
provides a convenient place for storage and easy retrieval of notes, maps, toll tickets or stubs and
other paper items that may be required or desired while driving. The paperclip is located near the
front of the overhead console and is secured in the overhead console housing by four screws.
The paperclip is available for service replacement, but it cannot be adjusted or repaired. If the
paperclip is damaged or faulty it must be replaced.
COMPASS/MINI-TRIP COMPUTER
The compass mini-trip computer is located in the overhead console on models equipped with this
option. The compass mini-trip computer units include the electronic control module, a
Vacuum-Fluorescent Display (VFD), a compass sensor unit and two push button function switches.
The compass mini-trip computer module contains a central processing unit and interfaces with
other electronic modules in the vehicle on the Programmable Communication Interface (J1850)
data bus network. The J1850 data bus network allows the sharing of sensor information. This helps
to reduce wire harness complexity, reduce internal controller hardware, and reduce component
sensor current loads. At the same time, this system provides increased reliability, enhanced
diagnostics, and allows the addition of many new feature capabilities.
The compass mini-trip computer provides several electronic functions and features. Some of the
functions and features that the compass mini-trip computer module supports and/or controls,
include the following display options: Compass and temperature - provides the outside temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
- Trip Odometer (TRIP ODO) - shows the distance travelled since the last trip computer reset.
- Average fuel economy (AVG ECO) - shows the average fuel economy since the last trip computer
reset.
- Instant fuel economy (ECO) - shows the present fuel economy based upon the current vehicle
distance and fuel used information.
- Distance To Empty (DTE) - shows the estimated distance that can be travelled with the fuel
remaining in the fuel tank. This estimated distance is computed using the average miles-per-gallon
from the last 30 gallons of fuel used.
- Elapsed Time (ET) - shows the accumulated ignition-on time since the last trip computer reset.
- Blank screen - the compass mini-trip VFD is turned OFF.
The ambient temperature sensor is hard wired to the IWAC control head. Data input for all other
compass mini-trip computer functions, including VFD dimming level, is received through J1850
data bus messages. The compass mini-trip computer uses its internal programming and all of
these inputs to calculate and display the requested data. If the data displayed is incorrect, perform
the self-diagnostic tests. If these tests prove inconclusive, the use of a DRB scan tool and the
proper Diagnostic Procedures are recommended for further testing of the compass mini-trip
computer module and the J1850 data bus.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Accessories and Optional Equipment > Driver/Vehicle Information Display > Component
Information > Technical Service Bulletins > Page 6347
The compass mini-trip computer module cannot be repaired, and is available for service only as a
unit. This unit includes the push button switches and the plastic module and display lens. If any of
these components is faulty or damaged, the complete compass mini-trip computer module must be
replaced.
Compass
While in the compass/temperature mode, the compass will display the direction in which the vehicle
is pointed using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle in three complete circles, on level ground, in not less than
forty-eight seconds. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized, the demagnetizing and calibration
procedures found may be required to restore proper compass operation.
The compass mini-trip computer only operates with the ignition switch in the ON position. When the
ignition switch is turned to the ON position, all of the segments in the compass mini-trip computer
VFD will be turned OFF for one second, then the display will return to the last function being
displayed before the ignition was turned to the OFF position. With the ignition switch in the ON
position, momentarily depressing and releasing the Step push button switch will cause the
compass-mini-trip computer to change its mode of operation, and momentarily depressing and
releasing the U.S./Metric push button will cause the unit to toggle between U.S. and Metric
measurements. This compass mini-trip computer features several functions that can be reset. If
both the Step and U.S/Metric push buttons are depressed at the same time for more than one
second with the ignition switch in the On position, the trip computer information that can be reset is
reset. However, the reset will only occur if the function currently displayed is a function that can be
reset. The functions that can be reset are: TRIP ODO, AVG ECO, and ET.
For more information on the features and control functions of the compass mini-trip computer, see
the owner's manual in the vehicle glove box.
Thermometer
The thermometer displays the outside ambient temperature in whole degrees. The temperature
display can be changed from Fahrenheit to Celsius using the U.S./Metric push button. The
displayed temperature is not an instant reading of conditions, but an average temperature. It may
take the thermometer display several minutes to respond to a major temperature change, such as
driving out of a heated garage into winter temperatures.
When the ignition switch is turned to the OFF position, the last displayed temperature reading stays
in the thermometer unit memory. When the ignition switch is turned to the ON position again, the
thermometer will display the memory temperature if the engine coolant temperature is above about
52 °C (125 °F). If the engine coolant temperature is below about 52 °C (125 °F), the thermometer
will display the actual temperature sensed by the ambient temperature sensor. The thermometer
temperature display update interval varies with the vehicle speed.
The thermometer function is supported by an ambient temperature sensor. The sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the HVAC control head which sends temperature on J1850 data bus circuit. The ambient
temperature sensor is available as a separate service item.
NOTE: The compass mini-trip computer will display "OC" for temperatures below -40 °C and "SC"
for temperatures above 55 °C.
AMBIENT TEMPERATURE SENSOR
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.
UNIVERSAL TRANSMITTER
On some models a Universal Garage Door Opener (UGDO) transceiver is standard
factory-installed equipment. The UGDO transceiver is integral to the overhead console. The only
visible component of the UGDO are the three transmitter push buttons at the rear of the overhead
console. The three UGDO transmitter push buttons are identified with one, two or three raised
tactile bumps so that they be easily identified by sight or by feel.
Each of the three UGDO transmitter push buttons controls an independent radio transmitter
channel. Each of these three channels can be trained to transmit a different radio frequency signal
for the remote operation of garage door openers, motorized gate openers, home or Office lighting,
security systems or just about any other device that can be equipped with a radio receiver in the
286 to 399 MegaHertz (MHz) frequency range for remote operation. The UGDO is capable of
operating systems using either rolling code or non-rolling code technology.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Accessories and Optional Equipment > Driver/Vehicle Information Display > Component
Information > Technical Service Bulletins > Page 6348
The UGDO cannot be repaired, and is available for service only as a unit. This unit includes the
push button switches and the plastic module.
The UGDO operates on a non-switched source of battery current so the unit will remain functional,
regardless of the ignition switch position. For more information on the features, programming
procedures and operation of the UGDO, see the owner's manual in the vehicle glove box.

Inspect the following secondary ignition system components:
- Distributor cap and rotor
- Ignition coil
- Spark plugs
- Spark plug wire routing and condition.
Reroute the spark plug wires or replace the faulty components as required.
If the source of the RFI or EMI noise is identified as two-way mobile radio or telephone equipment,
check the equipment installation for the following:
- Power connections should be made directly to the battery, and fused as closely to the battery as
possible.
- The antenna should be mounted on the roof or toward the rear of the vehicle. Remember that
magnetic antenna mounts on the roof panel can adversely affect the operation of an overhead
console compass, if the vehicle is so equipped.
- The antenna cable should be fully shielded coaxial cable, should be as short as is practical, and
should be routed away from the factory-installed vehicle wire harnesses whenever possible.
- The antenna and cable must be carefully matched to ensure a low Standing Wave Ratio (SWR).
Fleet vehicles are available with an extra-cost RFI suppressed Powertrain Control Module (PCM).
This unit reduces interference generated by the PCM on some radio frequencies used in two-way
radio communications. However, this unit will not resolve complaints of RFI in the commercial AM
or FM radio frequency ranges.

Remote Switch: Description and Operation
A remote radio switch option is available on models equipped with the AM/FM/CD/cassette/3-band
graphic equalizer radio receiver and the high-line Central Timer Module (CTM). (Refer to
ELECTRONIC CONTROL MODULES/BODY CONTROL/CENTRAL TIMER MODULE DESCRIPTION).
Fig. 13 Remote Radio Switches
Two rocker-type switches are mounted in the sides of the rear (instrument panel side) steering
wheel trim cover. The switch on the left spoke is the seek switch and has seek up, seek down, and
preset station advance functions. The switch on the right spoke is the volume control switch and
has volume up, and volume down functions. The switch on the right spoke also includes a "mode"
control that allows the driver to sequentially select AM radio, FM radio, cassette player or CD
player. The two switches are retained in mounting holes located on each side of the rear steering
wheel trim cover by four latches that are integral to the switches.
The remote radio switches share a common steering wheel wire harness with the vehicle speed
control switches. The steering wheel wire harness is connected to the instrument panel wire
harness through the clockspring. (Refer to CLOCKSPRING - DESCRIPTION).
The remote radio switches are resistor multiplexed units that are hard wired to the high-line CTM
through the clockspring. The CTM monitors the status of the remote radio switches and sends the
proper switch status messages on the J1850 data bus network to the radio receiver. The electronic
circuitry within the radio is programmed to respond to these remote radio switch status messages
by adjusting the radio settings as requested.
For diagnosis of the CTM or the J1850 data bus, the use of a DRB scan tool and the proper
Diagnostic Procedures are recommended. For more information on the features and control
functions for each of the remote radio switches, see the owner's manual in the vehicle glove box.

Alarm Module: Description and Operation
Fig.10 Sentry Key Immobilizer Module
SENTRY KEY IMMOBILIZER MODULE
The Sentry Key Immobilizer Module (SKIM) is the primary component of the Sentry Key
Immobilizer System (SKIS). The SKIM is located on the right side of the steering column, below the
ignition lock cylinder housing and is concealed beneath the steering column shrouds. The molded
black plastic housing for the SKIM has an integral molded plastic halo-like antenna ring that
extends from one end. When the SKIM is properly installed on the steering column, the antenna
ring is oriented around the circumference of the ignition lock cylinder housing. A single integral
connector receptacle containing six terminal pins is located on the opposite end of the SKIM
housing from the antenna ring. A stamped metal mounting bracket secured to the SKIM housing
has a U-shaped clip formation that is used to secure the unit to the right lower flange of the steering
column jacket.
The SKIM cannot be adjusted or repaired. If faulty or damaged, the entire SKIM unit must be
replaced.
The Sentry Key Immobilizer Module (SKIM) contains a Radio Frequency (RF) transceiver and a
microprocessor. The SKIM transmits RF signals to, and receives RF signals from the Sentry Key
transponder through a tuned antenna enclosed within the molded plastic antenna ring integral to
the SKIM housing. If this antenna ring is not mounted properly around the ignition lock cylinder
housing, communication problems between the SKIM and the transponder may arise.
These communication problems will result in Sentry Key transponder-related faults. The SKIM also
communicates over the Programmable Communications Interface (PCI) data bus with the
Powertrain Control Module (PCM), the Electro Mechanical Instrument Cluster (EMIC) and/or the
DRB III scan tool.
The SKIM retains in memory the ID numbers of any Sentry Key transponder that is programmed
into it. A maximum of eight Sentry Key transponders can be programmed into the SKIM. For added
system security, each SKIM is programmed with a unique Secret Key code. This code is stored in
memory, sent over the PCI data bus to the PCM, and is encoded to the transponder of every
Sentry Key that is programmed into the SKIM. Therefore, the Secret Key code is a common
element that is found in every component of the Sentry Key Immobilizer System (SKIS). Another
security code, called a PIN, is used to gain access to the SKIM Secured Access Mode. The
Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key
transponder programming procedures. The SKIM also stores the Vehicle Identification Number
(VIN) in its memory, which it learns through a PCI data bus message from the PCM during SKIS
initialization.
In the event that a SKIM replacement is required, the Secret Key code can be transferred to the
new SKIM from the PCM using the DRB III® scan tool and the SKIS initialization procedure. Proper
completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the
new SKIM so that new keys will not be required. In the event that the original Secret Key code
cannot be recovered, SKIM replacement will also require new Sentry Keys. The DRB III scan tool
will alert the technician during the SKIS initialization procedure if new Sentry Keys are required.
When the ignition switch is turned to the ON position, the SKIM transmits an RF signal to the
transponder in the ignition key. The SKIM then waits for an RF signal response from the
transponder. If the response received identifies the key as valid, the SKIM sends a valid key
message to the PCM over the PCI data bus. If the response received identifies the key as invalid,
or if no response is received from the key transponder, the SKIM sends an invalid key message to
the PCM. The PCM will enable or disable engine operation based upon the status of the SKIM
messages. It is important to note that the default condition in the PCM is an invalid key; therefore, if
no message is received from the SKIM by the PCM, the engine will be disabled and the vehicle
immobilized after two seconds of running.

Dodge Workshop Manuals > Accessories and Optional Equipment > Relays and Modules - Accessories and Optional
Equipment > Alarm Module, (Vehicle Antitheft) > Component Information > Locations > Page 6399
The SKIM also sends SKIS indicator status messages to the EMIC over the PCI data bus to tell the
EMIC how to operate the SKIS indicator. This indicator status message tells the EMIC to turn the
indicator ON for about three seconds each time the ignition switch is turned to the ON position as a
bulb test. After completion of the bulb test, the SKIM sends indicator status messages to the EMIC
to turn the indicator off, turn the indicator ON, or to flash the indicator ON and OFF. If the SKIS
indicator flashes or stays ON solid after the bulb test, it signifies a SKIS fault. If the SKIM detects a
system malfunction and/or the SKIS has become inoperative, the SKIS indicator will stay ON solid.
If the SKIM detects an invalid key or if a key transponder-related fault exists, the SKIS indicator will
flash. If the vehicle is equipped with the Customer Learn transponder programming feature, the
SKIM will also send messages to the EMIC to flash the SKIS indicator and to generate a single
audible chime tone whenever the Customer Learn programming mode is being utilized. (Refer to
VEHICLE THEFT SECURITY - STANDARD PROCEDURE - SENTRY KEY TRANSPONDER
PROGRAMMING).
The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will
store fault information in the form of Diagnostic Trouble Codes (DTC's) in SKIM memory if a system
malfunction is detected. The SKIM can be diagnosed, and any stored DTC's can be retrieved using
a DRB III scan tool. Refer to the appropriate diagnostic information.

Lock Cylinder Switch: Description and Operation
DOOR CYLINDER LOCK SWITCH
A door cylinder lock switch is snapped onto the back of the key lock cylinder inside each front door.
The door cylinder lock switch is a resistor multiplexed momentary switch that is hard wired in series
between a body ground and the Central Timer Module (CTM) through the front door wire harness.
The door cylinder lock switches are driven by the key lock cylinders and contain three internal
resistors. One resistor is used for the neutral switch position, one for the Lock position, and one for
the Unlock position.
The door cylinder lock switches cannot be adjusted or repaired and, if faulty or damaged, they must
be replaced.
The door cylinder lock switches are actuated by the key lock cylinder when the key is inserted in
the lock cylinder and turned to the lock or unlock positions. The door cylinder lock switch closes a
path to ground through one of three internal resistors for the Central Timer Module (CTM) when the
front door key lock cylinder is in the Lock, Unlock, or Neutral positions. The CTM reads the switch
status through an internal pull-up, then uses this information as an input for both power lock system
and Vehicle Theft Security System (VTSS) operation.
The door cylinder lock switches and circuits can be diagnosed using conventional diagnostic tools
and methods.
LIFTGATE CYLINDER LOCK SWITCH
The liftgate cylinder lock switch is snapped onto the back of the liftgate key lock cylinder inside the
liftgate. The liftgate cylinder lock switch is a resistor multiplexed momentary switch that is hard
wired in series between a body ground and the Central Timer Module (CTM) through the liftgate
wire harness. The liftgate cylinder lock switch is driven by the key lock cylinder and contains three
internal resistors. One resistor is used for the neutral switch position, one for the Lock position and
one for the Unlock position.
The liftgate cylinder lock switch cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.

Remote Switch: Description and Operation
A remote radio switch option is available on models equipped with the AM/FM/CD/cassette/3-band
graphic equalizer radio receiver and the high-line Central Timer Module (CTM). (Refer to
ELECTRONIC CONTROL MODULES/BODY CONTROL/CENTRAL TIMER MODULE DESCRIPTION).
Fig. 13 Remote Radio Switches
Two rocker-type switches are mounted in the sides of the rear (instrument panel side) steering
wheel trim cover. The switch on the left spoke is the seek switch and has seek up, seek down, and
preset station advance functions. The switch on the right spoke is the volume control switch and
has volume up, and volume down functions. The switch on the right spoke also includes a "mode"
control that allows the driver to sequentially select AM radio, FM radio, cassette player or CD
player. The two switches are retained in mounting holes located on each side of the rear steering
wheel trim cover by four latches that are integral to the switches.
The remote radio switches share a common steering wheel wire harness with the vehicle speed
control switches. The steering wheel wire harness is connected to the instrument panel wire
harness through the clockspring. (Refer to CLOCKSPRING - DESCRIPTION).
The remote radio switches are resistor multiplexed units that are hard wired to the high-line CTM
through the clockspring. The CTM monitors the status of the remote radio switches and sends the
proper switch status messages on the J1850 data bus network to the radio receiver. The electronic
circuitry within the radio is programmed to respond to these remote radio switch status messages
by adjusting the radio settings as requested.
For diagnosis of the CTM or the J1850 data bus, the use of a DRB scan tool and the proper
Diagnostic Procedures are recommended. For more information on the features and control
functions for each of the remote radio switches, see the owner's manual in the vehicle glove box.

Road Temperature Sensor: Description and Operation
AMBIENT TEMPERATURE SENSOR
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Road Temperature Sensor: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.
The ambient temperature sensor circuit can also be diagnosed using the following Sensor Test,
and Sensor Circuit Test. If the temperature sensor and circuit are confirmed to be OK, but the
temperature display is inoperative or incorrect, refer to Compass Mini-Trip Computer in the
Diagnosis and Testing. For complete circuit diagrams, refer to Overhead Console in the Contents
of Wiring Diagrams.

Road Temperature Sensor: Description and Operation
AMBIENT TEMPERATURE SENSOR
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.

Component Information > Description and Operation > Page 6480
Road Temperature Sensor: Testing and Inspection
The thermometer function is supported by the ambient temperature sensor, a wiring circuit, and a
portion of the compass mini-trip computer module. If any portion of the ambient temperature sensor
circuit fails, the compass/thermometer display function will self-diagnose the circuit. An "SC" (short
circuit) will appear in the display in place of the temperature, when the sensor is exposed to
temperatures above 110 °C (230 °F), or if the sensor circuit is shorted. An "OC", (open circuit) will
appear in the display in place of the temperature, when the sensor is exposed to temperatures
below -50 °C (-58 ° F), or if the sensor circuit is open.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Central Timer Module: Vehicle Damage Warnings
Vehicle Damage Warnings
Before disconnecting any control module, make sure the ignition is "OFF". Failure to do so could
damage the module.
When testing voltage or continuity at any control module, use the terminal side (not the wire end) of
the connector. Do not probe a wire through the insulation; this will damage it and eventually cause
it to fail because of corrosion.
Be careful when performing electrical tests so as to prevent accidental shorting of terminals. Such
mistakes can damage fuses or components. Also, a second code could be set, making diagnosis of
the original problem more difficult,
Road Testing A Complaint Vehicle
Some complaints will require a test drive as part of the repair verification procedure. The purpose
of the test drive is to try to duplicate the diagnostic code or symptom condition.
CAUTION: BEFORE ROAD TESTING A VEHICLE, BE SURE THAT ALL COMPONENTS ARE
REASSEMBLED. DURING THE TEST DRIVE, DO NOT TRY TO READ THE DRB III SCREEN
WHILE IN MOTION. DO NOT HANG THE DRB III FROM THE REAR VIEW MIRROR OR
OPERATE IT YOURSELF. HAVE AN ASSISTANT AVAILABLE TO OPERATE THE DRB III.

Central Timer Module: Description and Operation Sytem Description
The body system on the 2001 DN consists of a combination of modules that communicate over the
PCI bus (Programmable Communication Interface multiplex system). Through the PCI bus,
information about the operation of vehicle components and circuits is relayed quickly to the
appropriate module(s). All modules receive all the information transmitted on the bus even though
a module may not require all information to perform its function. It will only respond to messages
"addressed" to it through a binary coding process. This method of data transmission significantly
reduces the complexity of the wiring in the vehicle and the size of wiring harnesses. All of the
information about the functioning of all the systems is organized, controlled, and communicated by
the PCI bus, which is described in the vehicle communication of this general information.

For additional information on the Base CTM refer to Instrument Panel, Gauges and Warning
Indicators / Audible Warning Device. See: Instrument Panel, Gauges and Warning
Indicators/Audible Warning Device
AIRBAG SYSTEM
The airbag system is designed to provide increased driver and passenger protection if the vehicle
is involved in a front end collision. The system is most effective when used in conjunction with the
seat belt system.
The Airbag Control Module (ACM) is an electronic module that monitors the airbag system for
proper operation, stores diagnostic trouble code (DTCs), controls the airbag warning lamp and
contains the sensor and actuator that is responsible for airbag deployment. There are no external
impact sensors. The ACM is mounted on a special bracket that is fastened to the floor of the truck
at the bottom of the instrument panel. It is located forward of the console. The ACM provides
diagnostic information (DTCs) to the technician through the DRB III via the PCI bus. Some circuits
are tested continuously; others are checked only under certain circumstances. The warning lamp is
driven with messages relayed to the Electro/Mechanical Instrument Cluster (EMIC) from the ACM
via the PCI bus.
The AIRBAG warning lamp is the only point at which "symptoms" of a system malfunction can be
observed by the customer. Whenever the ignition key is turned to the "run" or "start" position, the
airbag control module performs a lamp check by turning the AIRBAG warning lamp ON for 6 - 8
seconds. If the lamp remains OFF, it means that the ACM has checked the system and found it to
be free of discernible malfunctions. If the lamp remains ON, there could be an active fault in the
system or the circuit that operates the lamp may be shorted to ground. If the lamp comes ON and
stays ON for a period longer than 6 - 8 seconds, then goes OFF, there is usually an intermittent
problem in the system.
WARNING: THE AIRBAG CONTROL MODULE CONTAINS THE IMPACT SENSOR, WHICH ENABLES THE
SYSTEM TO DEPLOY THE AIRBAG. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY
AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR
TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
- NEVER STRIKE OR KICK THE AIRBAG CONTROL MODULE, AS IT CAN DAMAGE THE
IMPACT SENSOR OR AFFECT ITS CALIBRATION. IF AN AIRBAG CONTROL MODULE IS
ACCIDENTALLY DROPPED DURING SERVICE, THE MODULE MUST BE SCRAPPED AND
REPLACED WITH A NEW UNIT.
Seat Belt Tensioner
Front seat belt systems incorporate Tensioner Modules (SBT). At the onset of an impact event
each tensioner uses a pyrotechnic device, which is triggered simultaneously with the airbags, to
rapidly retract the seat belts. With the slack removed, the occupant's forward motion in an impact
will be reduced as will the likelihood of contacting interior components. After an impact that deploys
the airbag, the seat belt tensioner assembly must be replaced.
The ACM module monitors the Seat Belt Tensioners circuit resistance and reports active and
stored DTC's if any problem is found.
Airbag Diagnostic Trouble Codes
Airbag diagnostic trouble codes consist of active and stored codes. If more than one code exists,
diagnostic priority should be given to the active codes.
Each diagnostic trouble code is diagnosed by following a specific testing procedure. The diagnostic
test procedures contain step-by-step instructions for determining the cause of the trouble codes. It
is not necessary to perform all of the tests in this book to diagnose an individual code.
Always begin by reading the diagnostic trouble codes using the DRB III.
Active diagnostic trouble codes for the airbag system are not permanent and will change the
moment the reason for the code is corrected. In certain test procedures, diagnostic trouble codes
are used as a diagnostic tool.
Active Codes
The code becomes active as soon as the malfunction is detected and stored after one minute of
occurrence or key-off, whichever occurs first. An active trouble code indicates an on-going
malfunction. This means that the defect is currently there every time the airbag control module
checks that circuit/function. It is impossible to erase an active code; active codes automatically
erase by themselves when the reason for the code has been corrected.
With the exception of the warning lamp trouble codes or malfunctions, when a malfunction is
detected, the airbag lamp remains lit for a minimum
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module <--> [Body Control Module]
> Component Information > Description and Operation > Sytem Description > Page 6526
of 12 seconds or as long as the malfunction is present.
Stored Codes
Airbag codes are automatically stored in the ACM's memory after one minute of occurrence or
when the ignition is turned OFF. The exception is the "Loss of Ignition Run Only" code which is an
active code only.
A "stored" code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
When a trouble code indicates there was an active code present at some time. However, the code
currently may not be present as an active code, although another active code could be.
The minimum time shown for any code will be one minute, even if the code was actually present for
less than one minute. Thus, the time shown for a code that was present for two minutes 13
seconds, for example, would be three minutes.
If a malfunction is detected a diagnostic trouble code is stored and will remain stored as long as the
malfunction exists. When and if the malfunction ceases to exist, an ignition cycle count will be
initiated for that code. If the ignition cycle count reaches 100 without a reoccurrence of the same
malfunction, that diagnostic trouble code is erased and that ignition cycle counter is reset to zero. If
the malfunction reoccurs before the count reaches 100, then the ignition cycle counter will be reset
and the diagnostic trouble code will continue to be a stored code.
If a malfunction is not active while performing a diagnostic test procedure, the active code
diagnostic test will not locate the source of the problem. In this case, the stored code can indicate
an area to inspect.
If no obvious problems are found, erase stored codes, and with the ignition "ON" wiggle the wire
harness and connectors, rotate the steering wheel from stop to stop. Recheck for codes
periodically as you work through the system. This procedure may uncover a malfunction that is
difficult to locate.
AUDIO SYSTEM
The factory installed radio receiver communicates on the Programmable Communication Interface
(PCI) data bus network through a separate two-way wire harness connector. This is used for the
remote radio switches that are mounted to the steering wheel, and also used for radio diagnosis
with the DRB III.
The remote radio switches are resistor multiplexed units that are hard wired to the CTM through the
clockspring. The CTM monitors the status of the remote radio switches and sends the proper
switch status messages on the PCI data bus network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by
adjusting the radio settings as requested.
When troubleshooting output shorts or "output" error messages, the following applies: On radios
without an external amplifier, the term "output" refers to the path between the radio and the
speaker. This type of circuit can be monitored all the way through the speaker connections by the
radio assembly. When the radio displays a shorted output DTC with this type of system, the
speaker, radio or wiring could be at fault. The output DTC could refer to a front or rear output or a
left or right output. The reason for the difference is the pairing of the output sections of the radio.
Some are paired left and right, others are paired front and rear.
On radios with an external amplifier, the term "output" refers to the circuit between the radio
connector and the amplifier. The radio is capable of monitoring only this portion and can tell nothing
about the circuit between the amplifier and the speakers. Consequently, a shorted output DTC on
this type of system would only refer to this circuit. A faulty speaker could not cause this DTC.
CENTRAL TIMER MODULE
The Durango (DN) utilizes a Central Timer Module (CTM). This system is available in a Base or
Highline configuration.
The CTM performs most of the typical functions a Body Control Module would perform.
The Base and Highline CTM provides the following features: Battery Saver Functions For Exterior and Interior Lamps
- Cargo Lamps
- Chime Warning
- Courtesy Lamps
- Dome Lamps
- Dome Defeat
- Door Ajar Switch Status
- Fog Lamps
- Head Lamp Time Delay
- Intermittent Wiper Controls
- Low and High Beam Head Lamps
- Optical Horn
- Park Lamps

- Remote Radio
- Remote Keyless Entry
- Vehicle Theft Alarm (VTSS)
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
CHIME SYSTEM
The chime system is built into the CTM. There are two chime rates, Low: 50 chimes per minute for
reminders and High: 180 chimes per minute for serious conditions that require immediate attention.
The high rate chime sounds when the key is left in the ignition and the driver's door is open or if the
headlights or the courtesy lights are left on. The low rate chime sounds for any of the other
conditions. There is a variable rate feature that allows the chime to sound continuously for key-in
and headlamp warning as long as the door is open. The seat belt warning chime is activated for six
seconds, and all other chime conditions will activate the chime once at the same time the warning
light on the cluster is illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
COMPASS MINI-TRIP COMPUTER (CMTC)
This system, located in the overhead console, displays information on outside temperature,
compass direction and trip information.
Compass and Temperature Display This display provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is facing.
Trip Odometer (ODO) Shows the distance traveled since the last reset.
Average Fuel Economy (AVE ECO) Shows the average fuel economy in MPG (miles per gallon) or
L/100 Km since the last reset.
Instant Fuel Economy Shows the fuel economy for the last few seconds in MPG or L/100 Km.
Distance to Empty (DTE) Shows the estimated distance that can be traveled with the fuel
remaining in the tank. This is calibrated using the MPG for the last few minutes.
Elapsed Time (ET) Shows the accumulated ignition ON time since the last reset.
Step Button Press this button to cycle through all the mini-trip computer displays.
US/M Button Press this button to convert all vehicle displays from US to Metric to US.
To Reset the Display Press the Step and US/M buttons simultaneously for at least two seconds
and all resettable conditions will be reset. This will occur only if a resettable function (AVG ECO,
ECO, ET) is currently being displayed.

Automatic Compass Calibration This compass is self calibrating which eliminates the need to
manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL
symbol will be displayed. After completing three 360' turns in an area free from large metal or
metallic objects, the CAL symbol will turn OFF and the compass will function normally.
Compass Variance Compass Variance is the difference between Magnetic North and Geographic
North. In some areas of the country, the difference between Magnetic and Geographic North is
great enough to cause the compass to give false readings. If this occurs, the compass variance
must be set.
To Set the Variance Turn the ignition ON and set display to Comp./Temp. while pressing the US/M
button, press the STEP button for approximately five seconds. The "VAR" symbol will light and the
last variance zone number will be displayed. Press the US/Metric Button to select the proper
variance zone as shown on the map. Press the Step button to set the new variance zone and
resume normal operation.
ELECTRO/MECHANICAL INSTRUMENT CLUSTER (EMIC)
The Instrument Cluster contains a Fuel, Voltmeter, Coolant Temp, and Oil Pressure gauge, a
Tachometer and a Speedometer. With the exception of the Voltmeter, the cluster positions the
gauges with PCI Bus messages received from the PCM. The Voltmeter operates directly off of the
Fused B+ Switched Ignition Output circuit that supplies ignition voltage for the cluster.
The Instrument Cluster also contains warning indicators that are illuminated by hard wired inputs or
by messages received from other modules on the PCI Bus.
The Trip/Total Odometer is a Vacuum Fluorescent Display (VF) that is controlled by PCI Bus
messages received from the PCM.
The cluster illumination lamps are hard wired in the Instrument Cluster. When the Park or
Headlamps are turned ON, the cluster receives a dimmed battery feed from the Headlamp Switch.
The cluster I/O Processor controls the VF display dimming and also sends dimming level
messages on the PCI Bus.
The EMIC will communicate with the DRB III to display PCI Engine Info, PCI Bus Info, and certain
input/outputs. Cluster diagnostic capabilities that the DRB III will actuate are limited to the Cluster
Calibration Points for the gauges. The DRB III can also extract active and stored Diagnostic
Trouble Codes (DTC) from the Instrument Cluster.
The EMIC is also capable of performing a diagnostic Self-Test that is actuated by depressing and
holding the Odometer trip reset stalk while cycling the ignition from the OFF to the ON position.
After the cluster Odometer displays CHEC, releasing the reset stalk begins the test. The cluster will
then position all of the gauges at specified calibration points and will illuminate all the PCI Bus
controlled indicators. The cluster will also illuminate each segment of the VF display.
The EMIC can verify communications with the PCM, ID the module, or change the country code
using the DRB III.
ENHANCED ACCIDENT RESPONSE (HIGHLINE CTM ONLY)
If the Airbag Control Module (ACM) deploys the airbags, a message is transmitted over the PCI
bus to the CTM module to unlock the doors. The interior lights will be turned ON when the vehicle
speed message on the PCI bus indicates 0 mph or the message is not present. In addition to
unlocking the doors, the door lock feature will be disabled for a predetermined amount of time
following the deployment. Once the ignition key has been cycled to the "OFF" position, normal
operation will resume.
EXTERIOR LIGHTING
The low and high beam headlamps are controlled directly by an output from the Central Timer
Module (CTM). The park lamps and fog lamps (on vehicle so equipped) are controlled via external
relays that are energized by the CTM. The headlamp switch provides the control signal through the
multifunction switch to the CTM, which indicates low or high beam operation.
The Optical Horn (Flash to Pass) feature operates both the high beam and low beam headlamps.
The CTM provides the Headlamp Time Delay feature. To start the delay, turn the ignition OFF
while the headlamps are ON. Then turn the headlamp switch to the OFF position. This has to be
done within 45 seconds of the ignition being turned OFF. The headlamps will remain ON for 60 ± 5
seconds. If during this delay period the headlamp switch is turned ON and then OFF, or ignition
switch is turned ON delay will be canceled and they will turn OFF immediately. During the delay
period, only headlamps are turned ON and park lamps/fog lamps are turned OFF.
The CTM also provides battery protection to avoid wearing down the battery if the customer leaves
the park lamps or headlamps ON for extended period of time with the ignition OFF. If the park
lamps or headlamps remain ON for more than 5 minutes while the ignition is OFF, the headlamps
and park lamps shall be turned off and the input causing the lamps to be ON will be ignored until
the input is corrected. Once the 5 minute timeout has extinguished the headlamps and park lamps,
any change in the ignition switch, door ajar switches, headlamps switch or park lamp switch will
reset the 5 minute timer and return the headlamps and park lamps to normal operation.

HEATING & A/C SYSTEM
The all-new heating and air conditioning system for DN provides more heating and cooling capacity
than in previous years. Depending on the model, either a Dual-Zone Air Conditioning System or a
Three-Zone Air Conditioning System is currently available in these vehicles.
Air Distribution (Front)
The front compartment HVAC unit has four fully adjustable instrument panel outlets. Side-window
demister outlets in the instrument panel eliminate the need for door ducts and door-to-instrument
panel seals. A single central mounted outlet delivers air for defrosting the windshield. Two outlets,
one on each side of the center console underneath the instrument panel, provide airflow to the
driver floor area and to the front seat passenger floor area. While two additional outlets, one on
each side of the center console near the rear of the front seats, distribute both heated and cooled
air across the floor to the intermediate seat passengers. Ducts in the center of the vehicle
underneath the carpet deliver air from the front compartment HVAC unit to the two intermediate
passenger outlets.
Door Actuator Control
A simplified control system for operation of the mode, recirculation, and temperature control
actuators provides positive positioning without the complexity of feedback from position sensors.
The A/C - Heater Control Module knows the number of operating actuator revolutions required for
full door travel as well as the number of actuator commutator pulses per revolution. Using these
parameters, the A/C - Heater Control Module runs the actuator for the number of commutator
pulses that correspond to the desired door position. To maintain accuracy, the system recalibrates
itself periodically at known zero and full travel conditions.
The dual sliding Blend switches have multiple detents to control the full range of temperature that
the system can produce in any mode. On Dual-Zone systems, the upper slide pot controls the
driver-side blend door and the lower slide pot controls the passenger-side blend door. On
Three-Zone systems, the upper slide pot controls the driver-side blend door, while the lower slide
pot controls the passenger-side blend door and the rear A/C - heater unit blend door.
The single rotary Mode switch has 12 detents to either direct airflow to the panel outlets, to a mix of
floor and panel outlets, to the floor outlets, to a mix of floor and defrost outlets, or to the defrost
outlet. Rotating the Mode switch to either of the two MAX positions results in the A/C - Heater
Control Module sending a signal to the recirculation actuator to close the fresh-air door. While
rotating the Mode switch to any other position results in the A/C - Heater Control Module sending a
signal to the recirculation actuator to open the fresh-air door.
When the Blower switch is OFF, the A/C - Heater Control Module closes the fresh-air door to
prevent outside air from entering the vehicle. On Three- Zone systems, the Mode switch also
controls the rear A/C - heater unit mode door, which directs rear airflow either to the right quarter
trim panel outlet or to the overhead outlets.
Front Blower Control
The front blower circuitry employs a new resistor technology to control front blower speed. Called
the "credit card" resistor, the device looks much like its name in that it is thin and compact like a
credit card. The credit card resistor, like the coil resistor used in previous years, mounts inside the
front HVAC housing assembly in the airflow path. However, unlike the coil resistor, the credit card
resistor offers much less airflow restriction.
A/C Operation
The A/C - Heater Control Module monitors the temperature of the evaporator to keep it just above
freezing for maximum cooling and dehumidification. A thermistor (temperature variable resistor)
placed between the evaporator fins provides the signal for the control. The Powertrain Control
Module (PCM) cycles the compressor on and off with a signal from the A/C - Heater Control
Module.
Heater Operation
To assist the HVAC system in maintaining a consistent and optimum heat output at low vehicle
speeds, an electric coolant pump operates under specific conditions to keep a steady flow of hot
coolant circulating through the heater circuit. The A/C - Heater Control Modules controls the
operation of the electric coolant pump. The pump runs when all of the following conditions are met:
When the vehicle's speed is below 27 Km/h (17 mph), the coolant temperature is between 65.5 °C
and 110 °C (150 °F and 230 °F), and the blend control is set above 60% reheat. The A/C - Heater
Control Module turns the pump OFF if any one of the following conditions occur: The vehicle speed
rises above 48.3 Km/h (30 mph). The coolant temperature drops below 65.5 °C (150 °F). The
coolant temperature rises above 110 °C (230 °F). The blend control is set below 60% reheat.
A/C - Heater Control (Rear)
The Three-Zone system allows the intermediate seat occupants to regulate the air temperature and
the fan speed of the rear unit from the rotary controls on the headliner mounted Rear A/C - Heater
Control.
HVAC Diagnostics
The A/C - Heater Control Module is fully addressable with the DRB III. Two of the Control Module's
diagnostic capabilities that the DRB III will actuate include the A/C Cool down Test to test A/C
system performance and the HVAC Door Recalibration Test to determine actuator travel span.
After performing either test, the Control Module will display one or more messages on the DRB III
screen. The message will indicate either that the HVAC system passed the test or that there is a
fault currently active in the HVAC system. The DRB III can also extract active and stored
Diagnostic Trouble Codes (DTCs) from the control module. Active DTCs are faults that currently
exit in the HVAC system. Stored DTCs are faults that occurred in the HVAC system since the
control module received the last "clear diagnostic info" message.

The Courtesy lights and illuminated entry feature are controlled by the Central Timer Module
(CTM). The CTM will activate the courtesy lamps, including Map Lights and the Dome Lights when
either the dome lamp switch is turned ON or a door is opened. The courtesy lamps will fade to OFF
immediately when all doors are closed with the dome lamp switch in the OFF position.
The illuminated entry feature operates under the following conditions: RKE "unlock"
- Driver/Passenger door is opened
- Unlocking either the driver or passenger using the key (vehicles equipped with security system)
- The dome lamp switch is turned ON
Once activated, the illuminated entry will "fade to OFF" after 3 to 5 seconds under the following
conditions: All doors are closed and: RKE "lock signal is received or
- Manual actuated power "lock" signal is received or
- Ignition switch is turned to the ON position or
- 30 seconds have elapsed without any other action
Addition RKE unlock actuation before the expiration of illuminated entry will not reset timer.
Opening any door before the 30 second timer expires, will reset the entry time to 30 seconds and
the illuminated entry timer will not begin counting down again until all doors are closed.
The Cargo lamps are controlled by the CTM. Placing the dome lamp switch in the cargo lamp
position grounds an input to the CTM. The CTM then sends voltage to the cargo lamps.
The Interior lamp defeat feature will not allow any interior lamp to be turned ON. This is
accomplished through an input to the CTM from the dome lamp switch.
The CTM provides battery protection by shutting down the interior lamps due to the following.
Leaving a door open, dome lamp switch ON, reading/vanity lamp switch ON or glove box door
open for more than 15 minutes while the ignition is OFF.
POWER DOOR LOCKS/REMOTE KEYLESS ENTRY
The CTM controls the door lock actuator assemblies to handle locking and unlocking with the key
fob or interior switch.
Vehicles that are equipped with the Vehicle Theft Security System will also have the central locking
feature. With the central locking feature, when the cylinder lock switch is turned to the lock position
all the doors will lock. For unlocking, if the key is turned to the unlock position once, only that door
will unlock. If the key is then turned a second time to the unlock position, all the doors will unlock.
There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is
OFF and the key is in the ignition.
Automatic or "rolling locks" are included as a programmable feature. If the vehicle is moving
approximately 15 mph and approximately 10 degrees of throttle opening is seen by the PCM, (the
PCM will send this info to the CTM via the PCI bus) indicating acceleration, the CTM will cycle the
lock actuators to lock the doors.
The highline CTM provides for Remote Keyless Entry (RKE)
The RKE system is placed in the programming mode by the DRB III, or by the customer program
features. The system will store up to four key fob codes. Two fobs are supplied with the truck,
additional fobs may be purchased through the parts department. Through the DRB III, erasing and
programming of one key fob without deleting the others is possible. If the key fob is stolen, all the
fob codes stored previously may be erased to provide the owner of the vehicle with an extra sense
of security.
VEHICLE COMMUNICATION
The Programmable Communication Interface or PCI Bus is a single wire multiplexed network
capable of supporting binary encoded messages shared between multiple modules. The PCI bus
circuit is identified as D25 and is violet with a yellow tracer. Additional tracer colors may be added
to the yellow in order to distinguish between different module connections. The modules are wired
in parallel. Connections are made in the harness using a splice.
The splice called the Diagnostic Junction Port, serves as the "Hub" of the bus. The Diagnostic
Junction Port provides an access point to isolate most of the modules on the bus in order to assist
in diagnosing the circuit. The following modules are used on the DN: Airbag Control Module
- A/C Heater Control
- Central Timer Module
- Controller Antilock Brake
- Compass Mini-Trip Computer
- Electro/Mechanical Instrument Cluster
- Powertrain Control Module
- Radio
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Body and Frame > Body Control Systems > Central Timer Module <--> [Body Control Module]
> Component Information > Description and Operation > Sytem Description > Page 6531
- Sentry Key Immobilizer Module
- Transfer Case Control Module
- Transmission Control Module
Each module provides its own bias and termination in order to transmit and receive messages. The
bus voltage is at zero volts when no modules are transmitting and is pulled up to about seven and
a half volts when modules are transmitting.
The bus messages are transmitted at a rate averaging 10800 bits per second. Since there is only
voltage present when the modules transmit and the message length is only about 500 milliseconds,
it is ineffective to try and measure the bus activity with a conventional voltmeter. The preferred
method is to use the DRB III lab scope. The 12v square wave selection on the 20-volt scale
provides a good view of the bus activity. Voltage on the bus should pulse between zero and about
seven and a half volts. Refer to the figure for some typical displays.
The PCI Bus failure modes are broken down into two categories. Complete PCI Bus
Communication Failure and individual module no response. Causes of complete PCI Bus
Communication Failure include a short to ground or battery on the PCI circuit. Individual module no
response can be caused by an open circuit at either the Diagnostic Junction Port or the module, or
an open battery or ground circuit to the affected module.
Symptoms of a complete PCI Bus Communication Failure would include but are not limited to: All gauges on the EMIC stay at zero
- All telltales on EMIC illuminate
- EMIC backlighting at full intensity
- Dashed lines in the Compass Mini-Trip Computer display

- No response received from any module on the PCI bus (except the PCM)
- No start (if equipped with Sentry Key immobilizer)
Symptoms of Individual module failure could include any one or more of the above. The difference
would be that at least one or more modules would respond to the DRB III.
Diagnosis starts with symptom identification. If a complete PCI Bus Communication Failure is
suspected, begin by identifying which modules the vehicle is equipped with and then attempt to get
a response from the modules with the DRB III. If any modules are responding, the failure is not
related to the total bus, but can be caused by one or more modules PCI circuit or power supply and
ground circuits. The DRB III may display "BUS +A SIGNAL OPEN" or "NO RESPONSE" to indicate
a communication problem. These same messages will be displayed if the vehicle is not equipped
with that particular module. The CCD error message is a default message used by the DRB III and
in no way indicates whether or not the PCI bus is operational. The message is only an indication
that a module is either not responding or the vehicle is not equipped.
VEHICLE THEFT SECURITY SYSTEM
The VTSS system monitors the door ajar switches, and ignition switch to detect unauthorized entry
into the vehicle. Once the vehicle is "armed", any one of these inputs can cause the VTSS system
to be tripped. Once tripped, the horn and lights will pulse for 3 minutes and if an attempt is made to
start the engine with a non-programmed SKIM key, it will start and stall. If the trigger condition is
still present, the lights will continue to flash for an additional 15 minutes, after which the system will
stop pulsing the lights and return to the "armed" state. The cause of the last 4 alarm triggers is
stored by the CTM and may be retrieved by the DRB III. The system may be disarmed by either an
unlock command from a valid RKE key fob by using a key in either door, or by using a valid SKIM
key in the ignition. The door key cylinders are equipped with disarm switches. There is also a VTSS
lamp on the dash that provides information to the driver about the state of the vehicle theft system.
WINDSHIELD WIPER SYSTEM
The DN truck is equipped with speed sensitive intermittent wipers. The low and high speeds are
controlled through the wiper stalk switch. The intermittent portion of the wiper control is handled by
the CTM through the intermittent wiper relay. When the module detects a decrease in delay time as
selected by the driver, an immediate wipe of the windshield takes place and the new delay interval
is implemented.

Central Timer Module: Symptom Related Diagnostic Procedures
Non-Trouble Code Procedures
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module.
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM
BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, SEAT BELT
TENSIONER, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE.
DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO
MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING
FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
NOTE: The following tests may not prove conclusive in the diagnosis of the Central Timer Module
(CTM). The most reliable, efficient, and accurate means to diagnose the CTM requires the use of a
DRB III scan tool. Refer to the appropriate diagnostic information.
1. Check the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20 ampere) in the Power
Distribution Center (PDC). If OK, go to Step 2. If not
OK, repair the shorted circuit or component as required and replace the faulty fuse.
2. Check for battery voltage at the fused B(+) fuses (Fuse 3 - 20 ampere, and Fuse 12 - 20
ampere) in the PDC. If OK, go to Step 3. If not OK,
repair the open B(+) circuit between the PDC and the battery as required.
3. Disconnect and isolate the battery negative cable. Disconnect the instrument panel wire harness
connector (Connector C3) for the CTM from the
CTM connector receptacle. Reconnect the battery negative cable. Check for battery voltage at
each of the two fused B(+) circuit cavities of the instrument panel wire harness connector
(Connector C3) for the CTM. If OK, disconnect and isolate the battery negative cable, reconnect
the instrument panel wire harness connector (Connector C3) for the CTM to the CTM connector
receptacle, and go to Step 4. If not OK, repair the open fused B(+) circuit(s) between the CTM and
the PDC as required.
4. Check the fused ignition switch output (run-start) fuse (Fuse 11 - 10 ampere) and the fused
ignition switch output (run-acc) fuse (Fuse 5 - 20
ampere) in the Junction Block (JB). If OK, go to Step 5. If not OK, repair the shorted circuit or
component as required and replace the faulty fuse(s).
5. Reconnect the battery negative cable. Turn the ignition switch to the ON position. Check for
battery voltage at the fused ignition switch output
(run-start) fuse (Fuse 11 - 10 ampere) and the fused ignition switch output (run-acc) fuse (Fuse 5 20 ampere) in the JB. If OK, go to Step 6. If not OK, repair the open fused ignition switch output
(run-start) circuit or fused ignition switch output (run-acc) circuit between the JB and the ignition
switch as required.
6. Turn the ignition switch to the OFF position. Disconnect and isolate the battery negative cable.
Disconnect the instrument panel wire harness
connector (Connector C1) for the CTM from the CTM connector receptacle. Reconnect the battery
negative cable. Turn the ignition switch to the ON position. Check for battery voltage at the fused
ignition switch output (run-start) circuit cavity and the fused ignition switch output (run-acc) cavity of
the instrument panel wire harness connector (Connector C1) for the CTM. If OK, go to Step 7. If not
OK, repair the open fused ignition switch output (run-start) circuit or fused ignition switch output
(run-acc) circuit between the CTM and the JB as required.
7. Turn the ignition switch to the OFF position. Check for continuity between each of the three
ground circuits in the instrument panel wire harness
connector (Connector C1) for the CTM and a good ground. In each case there should be continuity.
If OK, use a DRB III scan tool to perform further diagnosis of the CTM. Refer to the appropriate
diagnostic information. If not OK, repair the open ground circuit(s) to ground (G207 or G208) as
required.

Trunk / Liftgate Switch: Description and Operation
LIFTGATE AJAR SWITCH
The liftgate ajar switch is integral to the latch on the liftgate. The switch closes a path to ground for
the Central Timer Module (CTM) when the liftgate is opened, and opens the ground path when the
liftgate is closed.
The liftgate ajar switch cannot be repaired and, if faulty or damaged, the liftgate latch unit must be
replaced.
The liftgate ajar switch closes a path to ground for the Central Timer Module (CTM) when the
liftgate is opened, and opens the ground path when the liftgate is closed. The liftgate ajar switch is
connected in series between ground and the CTM to provide a unique input. The CTM reads the
switch status through an internal pull-up, then sends the proper switch status messages to other
electronic modules over the Programmable Communications Interface (PCI) data bus network. The
liftgate ajar switch can be diagnosed using conventional diagnostic tools and methods.

repair the shorted liftgate ajar switch sense circuit between the liftgate latch and the CTM as
required.
4. Check for continuity between the liftgate ajar switch sense circuit cavities of the body wire
harness connector (Connector C2) and the liftgate wire
harness connector for the liftgate latch. There should be continuity. If OK, use a DRB III scan tool
to diagnose the CTM. Refer to the appropriate diagnostic procedures. If not OK, repair the open
liftgate ajar switch sense circuit between the liftgate latch and the CTM as required.

DATE: Oct. 27, 2000
SUBJECT: Transmission Crossmember Service
MODELS: 2000 - 2001
(AN) Dakota
2000 - 2001 (DN) Durango
DISCUSSION: The fasteners that retain the transmission crossmember to the frame utilize a thread
lock patch on the threads of the fastener. The thread lock patch is required to help prevent the
fastener from loosening during normal vehicle usage. When the transmission crossmember is
required to be removed during service, the amount of thread patch material on the fastener will
deteriorate during fastener removal. To ensure that the fastener retention is not compromised after
service, the transmission crossmember fastener threads must have Mopar Lock & Seal p/n
04318031 added to the threads of each fastener.

HIGHLIGHTED WITH **ASTERISKS**. THE REVISION ADDS 2002 AND 2003 VEHICLES AND
REVISES THE PARTS TABLE.
SUBJECT: Intermittent Locking/Unlocking Of Doors Without Activating The Power Door Lock
Switch
OVERVIEW: This bulletin involves installing new door/liftgate lock cylinder switches.
MODELS:
**2000 - 2003** (AB) Ram Van/Wagon
**2000 - 2003** (AN) Dakota
**2000 - 2002** (BR/BE) Ram Truck
**2000 - 2003** (DN) Durango
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH VEHICLE THEFT SECURITY
SYSTEM (SALES CODE LSA).
SYMPTOM/CONDITION:
The door locks will intermittently lock and/or unlock without any activation of the power door lock
switch or a clicking sound may be heard coming from the power door locks (repeated locking or
repeated unlocking). The condition may occur more frequently in damp conditions such as driving
the vehicle in the rain or taking the vehicle through a car wash.
DIAGNOSIS:
Vehicles that demonstrate this condition may have water weeping into the door/liftgate lock cylinder
switches causing the switch to intermittently short across the internal circuit. This in turn may signal
the Central Timer Module (CTM) to activate the power door locks. Because of the nature of this
problem, it is extremely difficult to diagnose this condition. Therefore, customers that indicate their
doors intermittently lock and unlock without having the door lock switch activated or customers that
indicate they hear a repeated clicking noise coming from the door locks should have the Repair
Procedure performed on their vehicle.

Power Door Lock Actuator: Description and Operation
Models equipped with the optional power lock system have a power operated locking mechanism
located within each door and the liftgate. The lock mechanisms are actuated by a reversible electric
power lock motor. This motor is integral to the door latch unit within each door, but the liftgate lock
motor is a separate unit that operates the liftgate latch locking mechanism through a connecting
linkage rod. A single short pigtail wire with a molded plastic connector insulator connects each lock
motor to the vehicle electrical system through a take out and connector of the wire harness within
each door and the liftgate.
The power lock motors cannot be adjusted or repaired and, if faulty or damaged, the entire door
latch unit or the liftgate lock motor unit must be replaced.
The driver side front door power lock motor is controlled by a unique driver unlock relay output of
the Central Timer Module (CTM), while the remaining power lock motors are all connected in
parallel and share common CTM lock and unlock relay outputs. The driver side front door power
lock motor also shares the common lock relay output from the CTM. This circuit arrangement
makes the Remote Keyless Entry (RKE) system driver door unlock only feature option possible. A
positive and negative battery connection to the two power lock motor terminals will cause the
power lock motor plunger to move in one direction. Reversing the current through these same two
connections Will cause the power lock motor plunger to move in the opposite direction. The power
lock motors and circuits can be tested using conventional diagnostic tools and methods.

Power Door Lock Actuator: Testing and Inspection
Before you proceed with this diagnosis, confirm proper power lock switch, Central Timer Module
(CTM), and power lock switch output circuit operation. Remember, the CTM circuitry controls the
output to each of the power lock motors.
1. Check each power lock motor for correct operation while moving the power lock switch to both
the Lock and Unlock positions. If all of the power
lock motors are inoperative, go to Step 2. If one power lock motor is inoperative, go to Step 3.
2. If all of the power lock motors are inoperative, the problem may be caused by one shorted motor.
Disconnecting a shorted power lock motor from
the power lock circuit will allow the good power lock motor to operate. Disconnect the wire harness
connector from each power lock motor, one at a time, and recheck both the lock and unlock
functions by operating the power lock switch. If all of the power lock motors are still inoperative
after the above test, check for a short or open circuit between the power lock motors and the CTM.
If disconnecting one power lock motor causes the other motors to become functional, go to Step 3
to test the disconnected motor.
3. Once it has been determined which power lock motor is inoperative, that motor can be tested as
follows. Disconnect the wire harness connector
from the inoperative power lock motor. Apply 12 volts to the lock and unlock driver circuit cavities of
the power lock motor pigtail wire connector to check its operation in one direction. Reverse the
polarity to check the motor operation in the opposite direction. If OK, repair the shorted or open
lock or unlock driver circuits between the power lock motor and the CTM as required. If not OK,
replace the faulty power lock motor.

Power Door Lock Control Module: Description and Operation
DRIVER DOOR MODULE
A Driver Door Module (DDM) is used on all models equipped with power locks, power windows,
and power mirrors. The driver door module consists of a molded plastic housing that is secured
with three screws to a molded plastic switch bezel. The switch bezel is secured by metal snap clips
within an opening near the forward end of the arm rest in the driver side front door trim panel so
that the DDM can be serviced without removing the front door trim panel. Two integral connector
receptacles on the back of the DDM connect it to the vehicle electrical system through two take
outs and connectors of the left front door wire harness. The DDM houses the following switches: Power Lock Switch - The DDM includes a two-way, momentary, resistor multiplexed switch to
control the power lock system.
- Power Mirror Selector Switch - A three-position rocker switch in the DDM selects the right or left
power mirror for adjustment, or turns the power mirror system OFF.
- Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch in the DDM allows the
vehicle operator to lock out the power window switches on each passenger door so that the
passenger door power windows may be operated only from the master switches in the DDM.
- Power Window Switches - The DDM houses a two-way, momentary power window switch for the
driver side front door. This switch also has a second detent in the Down direction and internal
circuitry to provide an Auto-Down feature for the driver side front door power window. In addition to
the power window switch for its own door, the DDM houses individual master switches for each
passenger door power window.
The DDM also incorporates several green Light Emitting Diodes (LEDs) that illuminate the power
lock and power window switch paddles, and the power mirror switch directional buttons to improve
switch visibility in dark ambient lighting conditions. The DDM cannot be adjusted or repaired and, if
faulty or damaged, the entire DDM unit must be replaced.
The Driver Door Module (DDM) combines a power lock switch, a driver power window switch with
an Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit. The switches in the DDM can be diagnosed using conventional diagnostic tools and
methods.
Power Lock Switch The DDM power lock switch circuitry is connected in series between ground
and the driver door switch mux input of the Central Timer Module ( CTM). Each power lock switch
position (Lock, Unlock, and Neutral) provides a different resistance value to the CTM input, which
allows the CTM to sense the switch position. Based upon the power lock switch input, the CTM
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door and liftgate latches. The Light-Emitting Diode (LED) in the DDM power lock switch is
connected to battery current through the power window circuit breaker in the Junction Block (JB) on
a fused ignition switch output (run-acc) circuit so that the switch will be illuminated whenever the
ignition switch is in the ON or Accessory positions.
Power Window Switches The DDM power window switch circuitry is connected to battery current
through a circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc)
circuit so that the power windows will operate whenever the ignition switch is in the ON or
Accessory positions. Each two-way, momentary master passenger power window switch in the
DDM provides battery current and ground to the individual power window switches on each
passenger door so that the power window switch controls the battery current and ground feeds to
its respective power window motor. The DDM switch for the driver side front door power window is
labeled with the text "Auto" and includes an auto-down feature. When this switch is depressed to a
second momentary detent position and released, the driver door power window is automatically
operated through an internal circuit and relay to its fully lowered position. The Auto-down event is
cancelled if the switch paddle is depressed a second time in either the Up or Down direction. When
the two position window lockout switch in the DDM is depressed and latched in the lockout position,
the battery current feed to each of the individual passenger power window switches is interrupted
so that the passenger door power windows can only be operated from the master switches in the
DDM. The window lockout switch also controls the battery current feed for the LED in each
passenger power window switch so that the switch will not be illuminated when it is locked out.
Power Mirror Switches The DDM power mirror switch circuitry is connected to battery current
through a fuse in the JB on a fused B(+) circuit so that the power mirrors remain operational
regardless of the ignition switch position. A rocker type selector switch has three positions, one to
select the right mirror, one to select the left mirror, and a neutral OFF position. After the right or left
mirror is selected, one of four directional buttons is depressed to move the selected mirror Up,
Down, Right or Left. The DDM power mirror switch circuitry controls the battery current and ground
feeds to each of the four (two in each mirror head) power mirror motors. The Light-Emitting Diode
(LED) in the DDM power mirror switch is connected to battery current through the power window
circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc) circuit so that
the switch directional buttons will be illuminated whenever the ignition switch is in the ON or
Accessory positions.

Power Door Lock Switch: Description and Operation
The power lock system can be controlled by a two way, momentary, resistor multiplexed, single
gang switch on a power lock and window switch bezel located near the forward end of the armrest
on the passenger side front door trim panel. The power lock switch on the driver side front door trim
panel is integral to the driver door module. (Refer to POWER LOCKS/DRIVER DOOR MODULE DESCRIPTION). The power lock switch is secured by integral latch tabs in a molded plastic
receptacle on the back side of the power window and lock switch bezel so that only the switch
paddle is visible where it protrudes through the bezel. The power window and lock switch bezel is
secured by small metal snap clips within an opening near the forward end of the arm rest in the
passenger side front door trim panel so that the switches can be serviced without removing the
front door trim panel. An integral connector receptacle on the back of the switch connects it to the
vehicle electrical system through a take out and connector of the right front door wire harness. The
power lock switch has a green Light-Emitting Diode (LED) located in the switch paddle to improve
switch visibility in dark ambient lighting conditions. The power lock switch cannot be adjusted or
repaired and, if faulty or damaged, the switch unit must be replaced.
The two-way, momentary, power lock switch on the passenger side front door is connected in

HEATED MIRRORS
The optional heated mirror system only operates in concert with the rear defogger system, and will
be automatically turned OFF after a programmed time interval of about ten minutes. After the initial
time interval has expired, if the defogger switch is turned ON again during the same ignition cycle,
the heated mirror system will automatically turn OFF after about five minutes.
The heated mirror system will automatically shut OFF if the ignition switch is turned to the OFF
position, or it can be turned OFF manually by depressing the defogger switch a second time. Refer
to the owner's manual in the vehicle glove box for more information on the features, use and
operation of the heated mirror system.
When the rear window defogger switch is in the ON position, an electric heater grid located behind
the glass of each of the outside rear view mirrors is energized. When energized, each of these
heater grids produce heat to help clear the outside rear view mirrors of ice, snow, or fog.
The heated mirror system is controlled by a momentary rear window defogger switch in the HVAC
Control panel, which also includes the switch for the rear wiper and washer system. An amber
indicator lamp in the switch control will light to indicate when the defogger system is turned ON.
The HVAC control assembly also contains the defogger system control circuitry including the timer
logic and the defogger relay.
The heated mirror system only operates in concert with the rear defogger system, and will be

BASECOAT/CLEARCOAT FINISH
DESCRIPTION
The original equipment finish is a multi step process that involves cleaning, applying electro
deposition (E-coat), anti-chip primer, basecoat, and clearcoat steps.
On most vehicles a two-part paint application (basecoat/clearcoat) is used. Color paint that is
applied to primer is called basecoat. The clearcoat protects the basecoat from ultraviolet light and
provides a durable high-gloss finish.
CAUTION:
- Do not use abrasive chemicals or compounds on painted surfaces. Damage to finish can result.
- Do not use harsh alkaline based cleaning solvents on painted surfaces. Damage to finish or color
can result.

Power Door Lock Control Module: Description and Operation
DRIVER DOOR MODULE
A Driver Door Module (DDM) is used on all models equipped with power locks, power windows,
and power mirrors. The driver door module consists of a molded plastic housing that is secured
with three screws to a molded plastic switch bezel. The switch bezel is secured by metal snap clips
within an opening near the forward end of the arm rest in the driver side front door trim panel so
that the DDM can be serviced without removing the front door trim panel. Two integral connector
receptacles on the back of the DDM connect it to the vehicle electrical system through two take
outs and connectors of the left front door wire harness. The DDM houses the following switches: Power Lock Switch - The DDM includes a two-way, momentary, resistor multiplexed switch to
control the power lock system.
- Power Mirror Selector Switch - A three-position rocker switch in the DDM selects the right or left
power mirror for adjustment, or turns the power mirror system OFF.
- Power Mirror Adjustment Switches - Four momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
- Power Window Lockout Switch - A two-way, latching, push-button switch in the DDM allows the
vehicle operator to lock out the power window switches on each passenger door so that the
passenger door power windows may be operated only from the master switches in the DDM.
- Power Window Switches - The DDM houses a two-way, momentary power window switch for the
driver side front door. This switch also has a second detent in the Down direction and internal
circuitry to provide an Auto-Down feature for the driver side front door power window. In addition to
the power window switch for its own door, the DDM houses individual master switches for each
passenger door power window.
The DDM also incorporates several green Light Emitting Diodes (LEDs) that illuminate the power
lock and power window switch paddles, and the power mirror switch directional buttons to improve
switch visibility in dark ambient lighting conditions. The DDM cannot be adjusted or repaired and, if
faulty or damaged, the entire DDM unit must be replaced.
The Driver Door Module (DDM) combines a power lock switch, a driver power window switch with
an Auto-down feature, master switches for each passenger door power window, a power window
lockout switch, a power mirror selector switch, and four power mirror adjustment switches in a
single unit. The switches in the DDM can be diagnosed using conventional diagnostic tools and
methods.
Power Lock Switch The DDM power lock switch circuitry is connected in series between ground
and the driver door switch mux input of the Central Timer Module ( CTM). Each power lock switch
position (Lock, Unlock, and Neutral) provides a different resistance value to the CTM input, which
allows the CTM to sense the switch position. Based upon the power lock switch input, the CTM
controls the battery and ground feed outputs to the individual power lock motors to lock or unlock
the door and liftgate latches. The Light-Emitting Diode (LED) in the DDM power lock switch is
connected to battery current through the power window circuit breaker in the Junction Block (JB) on
a fused ignition switch output (run-acc) circuit so that the switch will be illuminated whenever the
ignition switch is in the ON or Accessory positions.
Power Window Switches The DDM power window switch circuitry is connected to battery current
through a circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc)
circuit so that the power windows will operate whenever the ignition switch is in the ON or
Accessory positions. Each two-way, momentary master passenger power window switch in the
DDM provides battery current and ground to the individual power window switches on each
passenger door so that the power window switch controls the battery current and ground feeds to
its respective power window motor. The DDM switch for the driver side front door power window is
labeled with the text "Auto" and includes an auto-down feature. When this switch is depressed to a
second momentary detent position and released, the driver door power window is automatically
operated through an internal circuit and relay to its fully lowered position. The Auto-down event is
cancelled if the switch paddle is depressed a second time in either the Up or Down direction. When
the two position window lockout switch in the DDM is depressed and latched in the lockout position,
the battery current feed to each of the individual passenger power window switches is interrupted
so that the passenger door power windows can only be operated from the master switches in the
DDM. The window lockout switch also controls the battery current feed for the LED in each
passenger power window switch so that the switch will not be illuminated when it is locked out.
Power Mirror Switches The DDM power mirror switch circuitry is connected to battery current
through a fuse in the JB on a fused B(+) circuit so that the power mirrors remain operational
regardless of the ignition switch position. A rocker type selector switch has three positions, one to
select the right mirror, one to select the left mirror, and a neutral OFF position. After the right or left
mirror is selected, one of four directional buttons is depressed to move the selected mirror Up,
Down, Right or Left. The DDM power mirror switch circuitry controls the battery current and ground
feeds to each of the four (two in each mirror head) power mirror motors. The Light-Emitting Diode
(LED) in the DDM power mirror switch is connected to battery current through the power window
circuit breaker in the Junction Block (JB) on a fused ignition switch output (run-acc) circuit so that
the switch directional buttons will be illuminated whenever the ignition switch is in the ON or
Accessory positions.

Seat Heater Control Module: Description and Operation
Fig. 8 Heated Seat Module - Typical
HEATED SEAT MODULE
Vehicles equipped with heated seats utilize a heated seat module. The heated seat module is
located under the heated seat switches, where it is secured to a mounting bracket that is also part
of the center console. The heated seat module has a single connector receptacle that allows the
module to be connected to all of the required inputs and outputs through the center console wire
harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the ignition switch, the two heated seat switches and the two
heated seat sensors to operate and control the heated seat elements in both front seats and the
two heated seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The
heated seat module is also programmed to perform self-diagnosis of certain heated seat system
functions and provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the ignition switch. The
module is grounded at all times through a ground screw located on the drivers B-pillar. Inputs to the
module include a resistor multiplexed heated seat switch request circuit for each of the two heated
seat switches and the heated seat sensor inputs from the seat cushions of each front seat. In
response to those inputs the heated seat module controls battery current feeds to the heated seat
elements and sensors, and controls the ground for the heated seat switch indicator lamps.
When a heated seat switch (Driver or Passenger) request signal is received by the heated seat
module, the module energizes the proper indicator lamp (Low or High) in the switch by grounding
the indicator lamp circuit to indicate that the heated seat system is operating. At the same time, the
heated seat module energizes the selected heated seat sensor circuit and the sensor provides the
module with an input indicating the surface temperature of the selected seat cushion.
The Low heat set point is about 35 °C (100.4 °F), and the High heat set point is about 42 °C (107.6
°F). If the seat cushion surface temperature input is below the temperature set point for the
selected temperature setting, the heated seat module energizes an N-channel Field Effect
Transistor (N-FET) within the module which energizes the heated seat elements in the selected
seat cushion and back. When the sensor input to the module indicates the correct temperature set
point has been achieved, the module de-energizes the N-FET which de-energizes the heated seat
elements. The heated seat module will continue to cycle the N-FET as needed to maintain the
selected temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch. Refer
to Heated Seat System and Heated Seat Module in Electronic Control Modules for the location of
the proper heated seat module diagnosis and testing procedures. Also refer to the Body Diagnostic
for additional diagnosis and testing procedures.

Power Seat Motor: Description and Operation
LUMBAR MOTOR
The 8-way power seat option includes an electrically operated lumbar support mechanism. The
only visible evidence of this option is the separate power lumbar switch control paddle that is
located on the outboard seat cushion side shield, next to the other power seat switch control knobs.
The power lumbar adjuster and motor are concealed beneath the seat back trim cover and
padding, where they are secured to the seat back frame.
The power lumbar adjuster cannot be repaired, and is serviced only as a unit with the seat back
frame. If the power lumbar adjuster or the seat back frame are damaged or faulty, the entire seat
back frame unit must be replaced. Refer to Bucket Seat Back in Body for the seat back frame
service procedures.
The power lumbar adjuster mechanism includes a reversible electric motor that is secured to the
seat back frame and is connected to a worm-drive gearbox. The motor and gearbox operate the
lumbar adjuster mechanism in the center of the seat back by extending and retracting a cable that
actuates a lever. The action of this lever compresses or relaxes a basket. The more this basket is
compressed, the more the slats bow outward against the center of the seat back padding, providing
additional lumbar support.

Power Seat Lumbar Adjuster and Motor Test
Actuate the power lumbar switch to move the power lumbar adjuster in each direction. The power
lumbar adjuster should move in both directions. It should be noted that the power lumber adjuster
normally operates very quietly and exhibits little visible movement. If the power lumbar adjuster
fails to operate in only one direction, move the adjuster a short distance in the opposite direction
and test again to be certain that the adjuster is not at its travel limit. If the power lumbar adjuster
still fails to operate in only one direction, refer to Power Lumbar Switch in the Diagnosis and
Testing. If the power lumbar adjuster fails to operate in either direction, perform the following tests.
1. Check the power seat fuse in the power distribution center. If OK, go to Step 2. If not OK,
replace the faulty power seat fuse. 2. Check for battery voltage at the power seat fuse in the power
distribution center. If OK, go to Step 3. If not OK, repair the open fused B(+) circuit
to the fuse in the Power Distribution Center as required.
3. Remove the outboard seat cushion side shield from the seat. Disconnect the seat wire harness
connector from the power lumbar switch connector
receptacle. Check for battery voltage at the fused B(+) circuit cavity of the power seat wire harness
connector for the power lumbar switch. If OK, go to Step 4, If not OK, repair the open fused B(+)
circuit to the power seat fuse in the power distribution center as required.
4. Check for continuity between the ground circuit cavity of the power seat wire harness connector
for the power lumbar switch and a good ground.
There should be continuity. If OK, go to Step 5. If not OK, repair the open ground circuit to ground

Power Seat Switch: Description and Operation
DRIVER POWER SEAT SWITCH
The power seat can be adjusted in six different ways using the power seat switch. The power seat
switch for some models has an additional switch knob for adjusting the power lumbar support. The
switch is located on the lower outboard side of the seat cushion on the seat cushion side shield on
all models. Refer to the owner's manual in the vehicle glove box for more information on the power
seat switch functions and the seat adjusting procedures.
The individual switches in the power seat switch module cannot be repaired. If one switch is
damaged or faulty, the entire power seat switch module must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or recliner through its drive unit in the selected
direction until the switch is released, or until the travel limit of the adjuster is reached. When the
switch is moved in the opposite direction, the battery feed and ground path to the motor are
reversed through the switch contacts. This causes the adjuster motor to run in the opposite
direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Seat Heater: Description and Operation
HEATED SEAT SYSTEM
Individually controlled electrically heated front seats are available factory-installed optional
equipment on the Durango models that are also equipped with the optional leather trim package.
Vehicles with this option can be visually identified by the two separate heated seat switches
mounted in the center console. The heated seat system allows the front seat driver and passenger
to select from two different levels of supplemental electrical seat heating, or no seat heating to suit
their individual comfort requirements. The heated seat system for this vehicle includes the following
major components: The heated seat switches, including two heated seat Light-Emitting Diode (LED) indicator lamps
and three back lighting LED's for each switch.
- The heated seat module, also referred to as the Seat Heat Interface Module (SHIM), which
contains the solid state electronic control and diagnostic logic circuitry for the heated seat system.
- The heated seat elements and sensors, which are integral to the individual front seat cushion and
front seat back trim covers.
Following are general descriptions of the major components in the heated seat system. See the
owner's manual in the vehicle glove box for more information on the features, use and operation of
the heated seat system. Refer to Power Seat for the location of complete heated seat system
wiring diagrams.
The heated seat module receives fused battery current through Junction Block (JB) only when the
ignition switch is in the run position. The heated seat switches receive battery current through a
fused ignition switch output (run) circuit only when the ignition switch is in the Run position. The
heated seat module shares a common ground circuit with each of the heated seat elements. The
heated seat elements will only operate when the surface temperature of the seat cushion cover at
the heated seat sensors is below the designed temperature set points of the system.
The heated seat module will automatically turn OFF the heated seat elements if it detects a short in
the heated seat element circuit or a heated seat sensor value that is out of range. The heated seat
system will also be turned OFF automatically whenever the ignition switch is turned to any position
except Run. If the ignition switch is turned to the OFF position the heated seat will remain OFF
after the ignition switch is turned to the ON position until a heated seat switch is depressed again.
The heated seat module monitors inputs from the heated seat sensors and the heated seat
switches. In response to these inputs the heated seat module uses its internal programming to
control outputs to the heated seat elements in both front seats and to control the heated seat LED
indicator lamps located in both of the heated seat switches. The heated seat module is also
programmed to provide a self-diagnostic capability. When the module detects certain failures within
the heated seat system, it will provide a visual indication of the failure by flashing the indicator
lamps in the heated seat switches.
DRIVER SEAT HEATER SWITCH
The heated seat switches used on vehicles with this option are both mounted in the center console.
The two switches are snapped into mounting holes in the center console. The two heated seat
switches are identical in appearance and construction, except for the location of a keyway in the
single connector receptacle and the housing on the back of each switch. The instrument panel wire
harness connectors for the heated seat switches are keyed to match the connector receptacles on
the switches so that the two heated seat switches can only be connected to the proper heated seat.
The momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal
to the heated seat module. Each switch has a center neutral position and momentary Low and High
positions so that both the driver and the front seat passenger can select a preferred seat heating
mode. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate
the selected mode (Low or High) of the seat heater for each seat and to provide diagnostic
feedback for the heated seat system. Each switch also has three other LED indicator lamps, which
provides back lighting of the switch nomenclature when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the indicator or back
lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the ON position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistor multiplexed voltage request signal
to the heated seat module to power the heated seat element of the selected seat and maintain the
requested temperature setting. If the heated seat switch is depressed to a different position (Low or
High) than the currently selected state, the heated seat module will change states to support the
new selection. If a heated seat switch is depressed a second time to the same position as the
currently selected state, the heated seat module interprets the second input as a request to turn the
seat heater OFF. The heated seat module will then turn the heated seat elements for that seat
OFF.
The indicator lamps in the heated seat switches receive battery current through a fused ignition
switch output (run) circuit when the ignition switch is in the ON position. The ground side of each
indicator lamp is controlled by a separate (high or low/driver or passenger) indicator lamp driver
circuit by the heated seat module. The heated seat module control of the switch indicator lamps
also allows the module to provide diagnostic feedback to the vehicle operator to indicate monitored
heated seat system faults by flashing the indicator lamps ON and OFF. One side of the back
lighting LED's in each heated seat switch are connected in series to ground at all times. The other
side of the LED's are connected to the ignition switch run circuit. These LED's are energized when
the ignition switch is turned to the Run position.
HEATED SEAT ELEMENT & SENSOR
One end of the heated seat element resistor wire is connected to a ground feed at all times through
a splice in the heated seat module ground

circuit. Battery current is directed to the other end of the heated seat element resistor wire by the
energized N-channel Field Effect Transistor (N-FET) located within the heated seat module. The
heated seat module will energize the N-FET only when the heated seat switch is in the Low or High
position and the heated seat sensor indicates that the seat cushion surface temperature is below
the selected (Low or High) temperature set point. As electrical current passes through the heating
element grid, the resistance of the wire used in the element disperses some of that electrical
current in the form of heat. The heat produced by the heated seat element grid then radiates
through the underside of the seat cushion and seat back trim covers, warming the seat cover and
its occupant.
The resistance of the heated seat sensor increases and decreases as the surface temperature of
the seat cushion cover changes. The heated seat module supplies each sensor with a voltage
feed, then detects the sensor resistance by monitoring the voltage of the separate sensor return
circuits. The heated seat module compares the heated seat sensor resistance (seat cushion
surface temperature) with the heated seat switch resistance (Low or High set point) to determine
when the heated seat element grids need to be cycled ON or OFF in order to maintain the selected
temperature set point.
PASSENGER SEAT HEATER SWITCH
The heated seat switches used on vehicles with this option are both mounted in the center console.
The two switches are snapped into mounting holes in the center console. The two heated seat
switches are identical in appearance and construction, except for the location of a keyway in the
single connector receptacle and the housing on the back of each switch. The instrument panel wire
harness connectors for the heated seat switches are keyed to match the connector receptacles on
the switches so that the two heated seat switches can only be connected to the proper heated seat.
The momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal
to the heated seat module. Each switch has a center neutral position and momentary Low and High
positions so that both the driver and the front seat passenger can select a preferred seat heating
mode. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate
the selected mode (Low or High) of the seat heater for each seat and to provide diagnostic
feedback for the heated seat system. Each switch also has three other LED indicator lamps, which
provides back lighting of the switch nomenclature when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the indicator or back
lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the ON position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistor multiplexed voltage request signal
to the heated seat module to power the heated seat element of the selected seat and maintain the
requested temperature setting. If the heated seat switch is depressed to a different position (Low or
High) than the currently selected state, the heated seat module will change states to support the
new selection. If a heated seat switch is depressed a second time to the same position as the
currently selected state, the heated seat module interprets the second input as a request to turn the
seat heater OFF. The heated seat module will then turn the heated seat elements for that seat
OFF.
The indicator lamps in the heated seat switches receive battery current through a fused ignition
switch output (run) circuit when the ignition switch is in the ON position. The ground side of each
indicator lamp is controlled by a separate (high or low/driver or passenger) indicator lamp driver
circuit by the heated seat module. The heated seat module control of the switch indicator lamps
also allows the module to provide diagnostic feedback to the vehicle operator to indicate monitored
heated seat system faults by flashing the indicator lamps ON and OFF. One side of the back
lighting LED's in each heated seat switch are connected in series to ground at all times. The other
side of the LED's are connected to the ignition switch run circuit. These LED's are energized when
the ignition switch is turned to the Run position.

Heated Seat System Self- Diagnosis Chart
SELF-DIAGNOSIS
The heated seat system is capable of performing some self-diagnostics. The following table depicts
the various failure modes which will be reported to the vehicle operator or technician by flashing the
individual heated seat switch Light Emitting Diode (LED) indicator lamps. See the Heated Seat
System Self-Diagnosis table for the diagnostic routines. The driver side heated seat switch
indicator lamps will flash if a failure occurs in the driver side heated seat, and the passenger side
heated seat switch indicator lamps will flash for a passenger side heated seat failure. If a monitored
heated seat system failure occurs, the switch indicator lamps will flash at a pulse rate of about
one-half second ON, followed by about one-half second OFF for a duration of about one minute
after the switch for the faulty heated seat is depressed in either the Low or High direction. This
process will repeat every time the faulty heated seat switch is actuated until the problem has been
corrected.

Seat Heater Control Module: Description and Operation
Fig. 8 Heated Seat Module - Typical
HEATED SEAT MODULE
Vehicles equipped with heated seats utilize a heated seat module. The heated seat module is
located under the heated seat switches, where it is secured to a mounting bracket that is also part
of the center console. The heated seat module has a single connector receptacle that allows the
module to be connected to all of the required inputs and outputs through the center console wire
harness.
The heated seat module is an electronic microprocessor controlled device designed and
programmed to use inputs from the ignition switch, the two heated seat switches and the two
heated seat sensors to operate and control the heated seat elements in both front seats and the
two heated seat indicator lamp Light-Emitting Diodes (LEDs) in each heated seat switch. The
heated seat module is also programmed to perform self-diagnosis of certain heated seat system
functions and provide feedback of that diagnosis through the heated seat switch indicator lamps.
The heated seat module cannot be repaired. If the heated seat module is damaged or faulty, the
entire module must be replaced.
The heated seat module operates on fused battery current received from the ignition switch. The
module is grounded at all times through a ground screw located on the drivers B-pillar. Inputs to the
module include a resistor multiplexed heated seat switch request circuit for each of the two heated
seat switches and the heated seat sensor inputs from the seat cushions of each front seat. In
response to those inputs the heated seat module controls battery current feeds to the heated seat
elements and sensors, and controls the ground for the heated seat switch indicator lamps.
When a heated seat switch (Driver or Passenger) request signal is received by the heated seat
module, the module energizes the proper indicator lamp (Low or High) in the switch by grounding
the indicator lamp circuit to indicate that the heated seat system is operating. At the same time, the
heated seat module energizes the selected heated seat sensor circuit and the sensor provides the
module with an input indicating the surface temperature of the selected seat cushion.
The Low heat set point is about 35 °C (100.4 °F), and the High heat set point is about 42 °C (107.6
°F). If the seat cushion surface temperature input is below the temperature set point for the
selected temperature setting, the heated seat module energizes an N-channel Field Effect
Transistor (N-FET) within the module which energizes the heated seat elements in the selected
seat cushion and back. When the sensor input to the module indicates the correct temperature set
point has been achieved, the module de-energizes the N-FET which de-energizes the heated seat
elements. The heated seat module will continue to cycle the N-FET as needed to maintain the
selected temperature set point.
If the heated seat module detects a heated seat sensor value input that is out of range or a shorted
or open heated seat element circuit, it will notify the vehicle operator or the repair technician of this
condition by flashing the High and/or Low indicator lamps in the affected heated seat switch. Refer
to Heated Seat System and Heated Seat Module in Electronic Control Modules for the location of
the proper heated seat module diagnosis and testing procedures. Also refer to the Body Diagnostic
for additional diagnosis and testing procedures.

Seat Heater Thermostat: Description and Operation
HEATED SEAT ELEMENT & SENSOR
One end of the heated seat element resistor wire is connected to a ground feed at all times through
a splice in the heated seat module ground circuit. Battery current is directed to the other end of the
heated seat element resistor wire by the energized N-channel Field Effect Transistor (N-FET)
located within the heated seat module. The heated seat module will energize the N-FET only when
the heated seat switch is in the Low or High position and the heated seat sensor indicates that the
seat cushion surface temperature is below the selected (Low or High) temperature set point. As
electrical current passes through the heating element grid, the resistance of the wire used in the
element disperses some of that electrical current in the form of heat. The heat produced by the
heated seat element grid then radiates through the underside of the seat cushion and seat back
trim covers, warming the seat cover and its occupant.
The resistance of the heated seat sensor increases and decreases as the surface temperature of
the seat cushion cover changes. The heated seat module supplies each sensor with a voltage
feed, then detects the sensor resistance by monitoring the voltage of the separate sensor return
circuits. The heated seat module compares the heated seat sensor resistance (seat cushion
surface temperature) with the heated seat switch resistance (Low or High set point) to determine
when the heated seat element grids need to be cycled ON or OFF in order to maintain the selected
temperature set point.

Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Body and Frame > Seats > Seat Track > Component Information > Description and Operation
Seat Track: Description and Operation
There are three reversible motors that operate the power seat adjuster. The motors are connected
to worm-drive gearboxes that move the seat adjuster through a combination of screw-type drive
units.
The front and rear of a seat are operated by different motors. They can be raised or lowered
independently of each other. When the center seat switch is pushed in the Up or Down direction,
both the front and rear motors operate in unison. The forward-rear-ward motor is operated by
pushing the center seat switch in the Forward or Rearward direction, which moves the entire seat
in the selected direction on all models.
Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or
frequent resetting of the circuit breakers must not be allowed to continue, or the motors may be
damaged. Make the necessary repairs.
The power seat adjuster and motors cannot be repaired, and are serviced only as a complete unit.
If any component in this unit is faulty or damaged, the entire power seat adjuster and motors
assembly must be replaced.
When a power seat switch is actuated, a battery feed and a ground path are applied through the
power seat switch contacts to the appropriate motor or motors. The motor and drive unit operate to
move the seat in the selected direction until the switch is released, or until the travel limit of the
power seat track is reached. When the switch is moved in the opposite direction, the battery feed
and ground path to the motor is reversed through the switch contacts. This causes the motor to run
in the opposite direction.

Seat Track: Testing and Inspection
Operate the power seat switch to move all three seat motors in each direction. The seat should
move in each of the selected directions. If the power seat track fails to operate in only one
direction, move the seat track a short distance in the opposite direction and test again to be certain
that the track is not at its travel limit. If the power seat track still fails to operate in only one
direction, refer to Diagnosis and Testing of the Power Seat Switch. If the power seat track fails to
operate in more than one direction, proceed as follows:
1. Check the power seat fuse in the power distribution center. If OK, go to Step 2. If not OK,
replace the faulty fuse. 2. Remove the power seat switch from the seat. Check for battery voltage
at the fused B(+) circuit cavity of the power seat switch wire harness
connector. If OK, go to Step 3. If not OK, repair the open circuit to the power distribution center as
required.
3. Check for continuity between the ground circuit cavity of the power seat switch wire harness
connector and a good ground. There should be
continuity. If OK, go to Step 4. If not OK, repair the open circuit to ground as required.
4. Test the power seat switch as described. If the switch tests OK, check the wire harness between
the power seat switch and the motor for shorts or
opens. If the circuits check OK, replace the faulty power seat track (adjuster) assembly. If the
circuits are not OK, repair the wire harness as required.

Power Door Lock Switch: Description and Operation
The power lock system can be controlled by a two way, momentary, resistor multiplexed, single
gang switch on a power lock and window switch bezel located near the forward end of the armrest
on the passenger side front door trim panel. The power lock switch on the driver side front door trim
panel is integral to the driver door module. (Refer to POWER LOCKS/DRIVER DOOR MODULE DESCRIPTION). The power lock switch is secured by integral latch tabs in a molded plastic
receptacle on the back side of the power window and lock switch bezel so that only the switch
paddle is visible where it protrudes through the bezel. The power window and lock switch bezel is
secured by small metal snap clips within an opening near the forward end of the arm rest in the
passenger side front door trim panel so that the switches can be serviced without removing the
front door trim panel. An integral connector receptacle on the back of the switch connects it to the
vehicle electrical system through a take out and connector of the right front door wire harness. The
power lock switch has a green Light-Emitting Diode (LED) located in the switch paddle to improve
switch visibility in dark ambient lighting conditions. The power lock switch cannot be adjusted or
repaired and, if faulty or damaged, the switch unit must be replaced.
The two-way, momentary, power lock switch on the passenger side front door is connected in
series between ground and the passenger door switch mux input of the Central Timer Module
(CTM). The power lock switch on the driver side front door trim panel is integral to the driver door
module. (Refer to POWER LOCKS/DRIVER DOOR MODULE - OPERATION). Each power lock
switch position Lock, Unlock, and Neutral provides a different resistance value to the CTM input
which allows the CTM to sense the switch position. Based upon the power lock switch inputs, the
CTM controls the battery and ground feed outputs to the power lock motors to lock or unlock the
door and liftgate latches. The Light-Emitting Diode (LED) in the paddle of the passenger door
power lock switch is connected to battery current through a fuse in the Junction Block (JB) on a
fused ignition switch output (run) circuit; therefore, the switch will only be illuminated when the
ignition switch is in the On position. The power lock switch can be diagnosed using conventional
diagnostic tools and methods.

When a power switch control knob or knobs are actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat track or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or recliner through its drive unit in the selected
direction until the switch is released, or until the travel limit of the adjuster is reached. When the
switch is moved in the opposite direction, the battery feed and ground path to the motor are
reversed through the switch contacts. This causes the adjuster motor to run in the opposite
direction.
No power seat switch should be held applied in any direction after the adjuster has reached its
travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect
them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.

Seat Heater Switch: Description and Operation
DRIVER SEAT HEATER SWITCH
The heated seat switches used on vehicles with this option are both mounted in the center console.
The two switches are snapped into mounting holes in the center console. The two heated seat
switches are identical in appearance and construction, except for the location of a keyway in the
single connector receptacle and the housing on the back of each switch. The instrument panel wire
harness connectors for the heated seat switches are keyed to match the connector receptacles on
the switches so that the two heated seat switches can only be connected to the proper heated seat.
The momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal
to the heated seat module. Each switch has a center neutral position and momentary Low and High
positions so that both the driver and the front seat passenger can select a preferred seat heating
mode. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate
the selected mode (Low or High) of the seat heater for each seat and to provide diagnostic
feedback for the heated seat system. Each switch also has three other LED indicator lamps, which
provides back lighting of the switch nomenclature when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the indicator or back
lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the ON position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistor multiplexed voltage request signal
to the heated seat module to power the heated seat element of the selected seat and maintain the
requested temperature setting. If the heated seat switch is depressed to a different position (Low or
High) than the currently selected state, the heated seat module will change states to support the
new selection. If a heated seat switch is depressed a second time to the same position as the
currently selected state, the heated seat module interprets the second input as a request to turn the
seat heater OFF. The heated seat module will then turn the heated seat elements for that seat
OFF.
The indicator lamps in the heated seat switches receive battery current through a fused ignition
switch output (run) circuit when the ignition switch is in the ON position. The ground side of each
indicator lamp is controlled by a separate (high or low/driver or passenger) indicator lamp driver
circuit by the heated seat module. The heated seat module control of the switch indicator lamps
also allows the module to provide diagnostic feedback to the vehicle operator to indicate monitored
heated seat system faults by flashing the indicator lamps ON and OFF. One side of the back
lighting LED's in each heated seat switch are connected in series to ground at all times. The other
side of the LED's are connected to the ignition switch run circuit. These LED's are energized when
the ignition switch is turned to the Run position.
PASSENGER SEAT HEATER SWITCH
The heated seat switches used on vehicles with this option are both mounted in the center console.
The two switches are snapped into mounting holes in the center console. The two heated seat
switches are identical in appearance and construction, except for the location of a keyway in the
single connector receptacle and the housing on the back of each switch. The instrument panel wire
harness connectors for the heated seat switches are keyed to match the connector receptacles on
the switches so that the two heated seat switches can only be connected to the proper heated seat.
The momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal
to the heated seat module. Each switch has a center neutral position and momentary Low and High
positions so that both the driver and the front seat passenger can select a preferred seat heating
mode. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate
the selected mode (Low or High) of the seat heater for each seat and to provide diagnostic
feedback for the heated seat system. Each switch also has three other LED indicator lamps, which
provides back lighting of the switch nomenclature when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the indicator or back
lighting lamps are faulty or damaged, the individual heated seat switch unit must be replaced.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit
when the ignition switch is in the ON position. Depressing the heated seat switch rocker to its
momentary High or Low position provides a hard-wired resistor multiplexed voltage request signal
to the heated seat module to power the heated seat element of the selected seat and maintain the
requested temperature setting. If the heated seat switch is depressed to a different position (Low or
High) than the currently selected state, the heated seat module will change states to support the
new selection. If a heated seat switch is depressed a second time to the same position as the
currently selected state, the heated seat module interprets the second input as a request to turn the
seat heater OFF. The heated seat module will then turn the heated seat elements for that seat
OFF.
The indicator lamps in the heated seat switches receive battery current through a fused ignition
switch output (run) circuit when the ignition switch is in the ON position. The ground side of each
indicator lamp is controlled by a separate (high or low/driver or passenger) indicator lamp driver
circuit by the heated seat module. The heated seat module control of the switch indicator lamps
also allows the module to provide diagnostic feedback to the vehicle operator to indicate monitored
heated seat system faults by flashing the indicator lamps ON and OFF. One side of the back
lighting LED's in each heated seat switch are connected in series to ground at all times. The other

Trunk / Liftgate Switch: Description and Operation
LIFTGATE AJAR SWITCH
The liftgate ajar switch is integral to the latch on the liftgate. The switch closes a path to ground for
the Central Timer Module (CTM) when the liftgate is opened, and opens the ground path when the
liftgate is closed.
The liftgate ajar switch cannot be repaired and, if faulty or damaged, the liftgate latch unit must be
replaced.
The liftgate ajar switch closes a path to ground for the Central Timer Module (CTM) when the
liftgate is opened, and opens the ground path when the liftgate is closed. The liftgate ajar switch is
connected in series between ground and the CTM to provide a unique input. The CTM reads the
switch status through an internal pull-up, then sends the proper switch status messages to other
electronic modules over the Programmable Communications Interface (PCI) data bus network. The
liftgate ajar switch can be diagnosed using conventional diagnostic tools and methods.

HIGHLIGHTED WITH **ASTERISKS**. THE REVISION ADDS 2002 AND 2003 VEHICLES AND
REVISES THE PARTS TABLE.
SUBJECT: Intermittent Locking/Unlocking Of Doors Without Activating The Power Door Lock
Switch
OVERVIEW: This bulletin involves installing new door/liftgate lock cylinder switches.
MODELS:
**2000 - 2003** (AB) Ram Van/Wagon
**2000 - 2003** (AN) Dakota
**2000 - 2002** (BR/BE) Ram Truck
**2000 - 2003** (DN) Durango
NOTE:
THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH VEHICLE THEFT SECURITY
SYSTEM (SALES CODE LSA).
SYMPTOM/CONDITION:
The door locks will intermittently lock and/or unlock without any activation of the power door lock
switch or a clicking sound may be heard coming from the power door locks (repeated locking or
repeated unlocking). The condition may occur more frequently in damp conditions such as driving
the vehicle in the rain or taking the vehicle through a car wash.
DIAGNOSIS:
Vehicles that demonstrate this condition may have water weeping into the door/liftgate lock cylinder
switches causing the switch to intermittently short across the internal circuit. This in turn may signal
the Central Timer Module (CTM) to activate the power door locks. Because of the nature of this
problem, it is extremely difficult to diagnose this condition. Therefore, customers that indicate their
doors intermittently lock and unlock without having the door lock switch activated or customers that
indicate they hear a repeated clicking noise coming from the door locks should have the Repair
Procedure performed on their vehicle.

Cruise Control Servo: Description and Operation
The servo unit consists of a solenoid valve body, and a vacuum chamber. The solenoid valve body
contains three solenoids:
- Vacuum
- Vent
- Dump
The vacuum chamber contains a diaphragm with a cable attached to control the throttle linkage.
The Powertrain Control Module (PCM) controls the solenoid valve body. The solenoid valve body
controls the application and release of vacuum to the diaphragm of the vacuum servo. The servo
unit cannot be repaired and is serviced only as a complete assembly.
Power is supplied to the servo's by the PCM through the brake switch. The PCM controls the
ground path for the vacuum and vent solenoids.
The dump solenoid is energized anytime it receives power. If power to the dump solenoid is
interrupted, the solenoid dumps vacuum in the servo. This provides a safety backup to the vent and
vacuum solenoids.
The vacuum and vent solenoids must be grounded at the PCM to operate. When the PCM grounds
the vacuum servo solenoid, the solenoid allows vacuum to enter the servo and pull open the
throttle plate using the cable. When the PCM breaks the ground, the solenoid closes and no more
vacuum is allowed to enter the servo. The PCM also operates the vent solenoid via ground. The
vent solenoid opens and closes a passage to bleed or hold vacuum in the servo as required.
The PCM duty cycles the vacuum and vent solenoids to maintain the set speed, or to accelerate
and decelerate the vehicle. To increase throttle opening, the PCM grounds the vacuum and vent
solenoids. To decrease throttle opening, the PCM removes the grounds from the vacuum and vent
solenoids. When the brake is released, if vehicle speed exceeds 30 mph to resume, 35 mph to set,
and the RES/ACCEL switch has been depressed, ground for the vent and vacuum circuits is
restored.

Cruise Control Switch: Description and Operation
There are two separate switch pods that operate the speed control system. The
steering-wheel-mounted switches use multiplexed circuits to provide inputs to the PCM for ON,
OFF, RESUME, ACCELERATE, SET, DECEL and CANCEL modes. Refer to the owner's manual
for more information on speed control switch functions and setting procedures.
The individual switches cannot be repaired. If one switch fails, the entire switch module must be
replaced.
When speed control is selected by depressing the ON, OFF switch, the PCM allows a set speed to
be stored in its RAM for speed control. To store a set speed, depress the SET switch while the
vehicle is moving at a speed between approximately 35 and 85 mph. In order for the speed control
to engage, the brakes cannot be applied, nor can the gear selector be indicating the transmission is
in Park or Neutral.
The speed control can be disengaged manually by:
- Stepping on the brake pedal
- Depressing the OFF switch
- Depressing the CANCEL switch.
The speed control can be disengaged also by any of the following conditions:
- An indication of Park or Neutral
- The VSS signal increases at a rate of 10 mph per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
- Depressing the clutch pedal.
- Excessive engine rpm (indicates that the transmission may be in a low gear)
- The VSS signal decreases at a rate of 10 mph per second (indicates that the vehicle may have
decelerated at an extremely high rate)
- If the actual speed is not within 20 mph of the set speed
The previous disengagement conditions are programmed for added safety.
Once the speed control has been disengaged, depressing the ACCEL switch restores the vehicle
to the target speed that was stored in the PCM's RAM.
NOTE: Depressing the OFF switch will erase the set speed stored in the PCM's RAM.
If, while the speed control is engaged, the driver wishes to increase vehicle speed, the PCM is
programmed for an acceleration feature. With the ACCEL switch held closed, the vehicle
accelerates slowly to the desired speed. The new target speed is stored in the PCM's RAM when
the ACCEL switch is released. The PCM also has a "tap-up" feature in which vehicle speed
increases at a rate of approximately 2 mph for each momentary switch activation of the ACCEL
switch.
The PCM also provides a means to decelerate without disengaging speed control. To decelerate
from an existing recorded target speed, depress and hold the COAST switch until the desired
speed is reached. Then release the switch. The ON, OFF switch operates two components: the
PCM's ON, OFF input, and the battery voltage to the brake switch, which powers the speed control
servo.
Multiplexing
The PCM sends out 5 volts through a fixed resistor and monitors the voltage change between the
fixed resistor and the switches. If none of the switches are depressed, the PCM will measure 5
volts at the sensor point (open circuit). If a switch with no resistor is closed, the PCM will measure 0
volts (grounded circuit). Now, if a resistor is added to a switch, then the PCM will measure some
voltage proportional to the size of the resistor. By adding a different resistor to each switch, the
PCM will see a different voltage depending on which switch is pushed.
Another resistor has been added to the 'at rest circuit' causing the PCM to never see 5 volts. This
was done for diagnostic purposes. If the switch circuit should open (bad connection), then the PCM
will see the 5 volts and know the circuit is bad. The PCM will then set an open circuit fault.

Cruise Control Vacuum Reservoir: Description and Operation
The vacuum reservoir is a plastic storage tank connected to an engine vacuum source by vacuum
lines.
The vacuum reservoir is used to supply the vacuum needed to maintain proper speed control
operation when engine vacuum drops, such as in climbing a grade while driving. A one-way check
valve is used in the vacuum line between the reservoir and the vacuum source. This check valve is
used to trap engine vacuum in the reservoir. On certain vehicle applications, this reservoir is
shared with the heating/air-conditioning system. The vacuum reservoir cannot be repaired and
must be replaced if faulty.

Cruise Control Vacuum Reservoir: Testing and Inspection
Vacuum Supply Test
1. Disconnect vacuum hose at speed control servo and install a vacuum gauge into the
disconnected hose. 2. Start engine and observe gauge at idle. Vacuum gauge should read at least
ten inches of mercury. 3. If vacuum is less than ten inches of mercury, determine source of leak.
Check vacuum line to engine for leaks. Also check actual engine intake
manifold vacuum. If manifold vacuum does not meet this requirement, check for poor engine
performance and repair as necessary.
4. If vacuum line to engine is not leaking, check for leak at vacuum reservoir. To locate and gain
access to reservoir, refer to Vacuum Reservoir
Removal/Installation. Disconnect vacuum line at reservoir and connect a hand-operated vacuum
pump to reservoir fitting. Apply vacuum. Reservoir vacuum should not bleed OFF. If vacuum is
being lost, replace reservoir.
5. Verify operation of one-way check valve and check it for leaks.
a. Locate one-way check valve. The valve is located in vacuum line between vacuum reservoir and
engine vacuum source. Disconnect vacuum
hoses (lines) at each end of valve.
b. Connect a hand-operated vacuum pump to reservoir end of check valve. Apply vacuum. Vacuum
should not bleed OFF. If vacuum is being
lost, replace one-way check valve.
c. Connect a hand-operated vacuum pump to vacuum source end of check valve. Apply vacuum.
Vacuum should flow through valve. If vacuum
is not flowing, replace one-way check valve. Seal the fitting at opposite end of valve with a finger
and apply vacuum. If vacuum will not hold, diaphragm within check valve has ruptured. Replace
valve.

The individual switches cannot be repaired. If one switch fails, the entire switch module must be
replaced.
When speed control is selected by depressing the ON, OFF switch, the PCM allows a set speed to
be stored in its RAM for speed control. To store a set speed, depress the SET switch while the
vehicle is moving at a speed between approximately 35 and 85 mph. In order for the speed control
to engage, the brakes cannot be applied, nor can the gear selector be indicating the transmission is
in Park or Neutral.
The speed control can be disengaged manually by:
- Stepping on the brake pedal
- Depressing the OFF switch
- Depressing the CANCEL switch.
The speed control can be disengaged also by any of the following conditions:
- An indication of Park or Neutral
- The VSS signal increases at a rate of 10 mph per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
- Depressing the clutch pedal.
- Excessive engine rpm (indicates that the transmission may be in a low gear)
- The VSS signal decreases at a rate of 10 mph per second (indicates that the vehicle may have
decelerated at an extremely high rate)
- If the actual speed is not within 20 mph of the set speed
The previous disengagement conditions are programmed for added safety.
Once the speed control has been disengaged, depressing the ACCEL switch restores the vehicle
to the target speed that was stored in the PCM's RAM.
NOTE: Depressing the OFF switch will erase the set speed stored in the PCM's RAM.
If, while the speed control is engaged, the driver wishes to increase vehicle speed, the PCM is
programmed for an acceleration feature. With the ACCEL switch held closed, the vehicle
accelerates slowly to the desired speed. The new target speed is stored in the PCM's RAM when
the ACCEL switch is released. The PCM also has a "tap-up" feature in which vehicle speed
increases at a rate of approximately 2 mph for each momentary switch activation of the ACCEL
switch.
The PCM also provides a means to decelerate without disengaging speed control. To decelerate
from an existing recorded target speed, depress and hold the COAST switch until the desired
speed is reached. Then release the switch. The ON, OFF switch operates two components: the
PCM's ON, OFF input, and the battery voltage to the brake switch, which powers the speed control
servo.
Multiplexing
The PCM sends out 5 volts through a fixed resistor and monitors the voltage change between the
fixed resistor and the switches. If none of the switches are depressed, the PCM will measure 5
volts at the sensor point (open circuit). If a switch with no resistor is closed, the PCM will measure 0
volts (grounded circuit). Now, if a resistor is added to a switch, then the PCM will measure some
voltage proportional to the size of the resistor. By adding a different resistor to each switch, the
PCM will see a different voltage depending on which switch is pushed.
Another resistor has been added to the 'at rest circuit' causing the PCM to never see 5 volts. This
was done for diagnostic purposes. If the switch circuit should open (bad connection), then the PCM
will see the 5 volts and know the circuit is bad. The PCM will then set an open circuit fault.

ABS Light: Description and Operation
An Antilock Brake System (ABS) indicator is standard equipment on all instrument clusters. This
indicator serves both the standard equipment Rear Wheel Anti-Lock (RWAL) and optional
equipment 4-Wheel Anti-Lock (4WAL) brake systems. The ABS indicator is located in the
Information Center area of the instrument cluster, to the left of center. The ABS indicator consists
of a stencilled cutout of the International Control and Display Symbol icon for "Failure of Anti-lock
Braking System" in the opaque layer of the instrument cluster overlay. The dark outer layer of the
overlay prevents the indicator from being clearly visible when it is not illuminated. An amber lens
behind the cutout in the opaque layer of the overlay causes the icon to appear in amber through
the translucent outer layer of the overlay when it is illuminated from behind by a Light Emitting
Diode (LED) soldered onto the instrument cluster electronic circuit board. The ABS indicator is
serviced as a unit with the instrument cluster.
The ABS indicator gives an indication to the vehicle operator when the ABS system is faulty or
inoperative. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and electronic messages received by the cluster from the Controller
Antilock Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The ABS
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the ABS indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the ABS indicator is
illuminated by the cluster for about two seconds as a bulb test.
- ABS Lamp-ON Message - Each time the cluster receives a lamp-ON message from the CAB, the
ABS indicator will be illuminated. The indicator remains illuminated until the cluster receives a
lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position,
whichever occurs first.
- Communication Error - If the cluster receives no lamp-ON or lamp-OFF messages from the CAB
for six consecutive seconds, the ABS indicator is illuminated. The indicator remains illuminated until
the cluster receives a valid message from the CAB, or until the ignition switch is turned to the OFF
position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the ABS indicator
will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
- ABS Diagnostic Test - The ABS indicator is blinked ON and OFF by lamp-ON and lamp-OFF
messages from the CAB during the performance of the ABS diagnostic tests.
The CAB continually monitors the ABS circuits and sensors to decide whether the system is in
good operating condition. The CAB then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. If the CAB sends a lamp-ON message after the bulb test, it indicates that the
CAB has detected a system malfunction and/or that the ABS system has become inoperative. The
CAB will store a Diagnostic Trouble Code (DTC) for any malfunction it detects. Each time the ABS
indicator fails to light due to an open or short in the cluster ABS indicator circuit, the cluster sends a
message notifying the CAB of the condition, and the CAB will store a DTC. For proper diagnosis of
the antilock brake system, the CAB, the PCI data bus, or the message inputs to the instrument
cluster that control the ABS indicator, a DRB III scan tool is required. Refer to the appropriate
diagnostic information.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).
2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit. 3.
Operate the item. 4. The voltmeter will show the difference in voltage between the two points.
Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Audible Warning Device: Description and Operation
For additional information on the Central Timer Module, refer to Powertrain Management /
Computers and Control Systems / Body Control Module. See: Body and Frame/Body Control
Systems/Central Timer Module
CHIME WARNING SYSTEM
A chime warning system is standard factory-installed equipment on this model. The chime warning
system uses a single chime tone generator that is integral to the Central Timer Module (CTM) to
provide an audible indication of various vehicle conditions that may require the attention of the
vehicle operator.
The chime warning system includes the following major components, which are described in further
detail elsewhere:
- Central Timer Module - The Central Timer Module (CTM) is located on the cowl side inner panel,
below the driver side end of the instrument panel. The CTM contains an integral chime tone
generator, integrated circuitry, a central processing unit, and the programming to provide all of the
proper chime warning system features based upon the monitored inputs. The CTM circuitry
monitors hard wired switch inputs as well as electronic messages received from other electronic
modules in the vehicle over the Programmable Communications Interface (PCI) data bus network.
- Door Ajar Switch - Door ajar switches are integral to each door latch. These switches provide
inputs to the chime warning system indicating whether a door is opened or closed.
- Headlamp Switch - The headlamp switch is located on the instrument panel outboard of the
steering column. The headlamp switch provides input to the chime warning system indicating
whether any interior or exterior lighting is turned ON or OFF.
- Ignition Switch - A key-in ignition switch is integral to the ignition switch. The key-in ignition switch
provides an input to the chime warning system indicating whether a key is present in the ignition
lock cylinder.
Hard wired circuitry connects many of the chime warning system components to each other
through the electrical system of the vehicle. These hard wired circuits are integral to several wire
harnesses, which are routed throughout the vehicle and retained by many different methods. These
circuits may be connected to each other, to the vehicle electrical system and to the chime warning
system components through the use of a combination of soldered splices, splice block connectors,
and many different types of wire harness terminal connectors and insulators.
The CTM chime warning system circuitry and the integral chime tone generator cannot be adjusted
or repaired. If the CTM or the chime tone generator are damaged or faulty, the CTM unit must be
replaced.
The chime warning system is designed to provide an audible output as an indication of various
conditions that may require the attention or awareness of the vehicle operator. The chime warning
system components operate on battery current received through a fused B(+) fuse in the Junction
Block (JB) on a non-switched fused B(+) circuit so that the system may operate regardless of the
ignition switch position.
The chime warning system provides an audible indication to the vehicle operator under the
following conditions:
- Compass Mini-Trip Computer (CMTC) Reset - The Central Timer Module (CTM) chime tone
generator will generate one chime tone each time a Programmable Communications Interface
(PCI) data bus message is received from the optional CMTC indicating that the CMTC data has
been reset.
- Door Ajar Warning - The CTM chime tone generator will generate repetitive chime tones at a slow
rate to announce that a hard wired input from any door ajar switch indicates that a door is open
with the ignition switch in the ON position. The chimes will continue to sound until the all doors are
closed or the ignition switch is turned to the OFF position, whichever occurs first.
- Fasten Seat Belt Warning - The CTM chime tone generator will generate repetitive chime tones at
a slow rate to announce that a hard wired input from the seat belt switch to the Electro-Mechanical
Instrument Cluster (EMIC) indicates that the driver side front seat belt is not fastened with the
ignition switch in the ON position. Unless the driver side front seat belt is fastened the chimes will
continue to sound for a duration of about seven seconds each time the ignition switch is turned to
the ON position, or until the driver side front seat belt is fastened, whichever occurs first. This
chime tone is based upon a PCI data bus chime request message input to the CTM from the EMIC,
but is not tied to the operation of the EMIC "Seatbelt" indicator.
- Head/Park/Courtesy Lights-On Warning - The CTM chime tone generator will generate repetitive
chime ones at a fast rate to announce that hard wired inputs from the driver door ajar switch,
headlamp switch, and ignition switch indicate that the exterior or courtesy lamps are turned ON
with the driver side front door opened and the ignition switch in the OFF position. The chimes will
continue to sound until the exterior or courtesy lamps are turned OFF, the driver side front door is
closed, or the ignition switch is turned to the ON position, whichever occurs first.
- Key-In-Ignition Warning - The CTM chime tone generator will generate repetitive chime tones at a
fast rate to announce that hard wired inputs from the driver door ajar switch, headlamp switch, and
ignition switch indicate that the key is in the ignition lock cylinder with the driver side front door
opened and the ignition switch in the OFF position. The chimes will continue to sound until the key
is removed from the ignition lock cylinder, the driver side front door is closed, or the ignition switch
is turned to the ON position, whichever occurs first.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device > Component
Information > Diagrams > Page 7203
- Overspeed Warning - The CTM chime tone generator will generate repetitive chime tones at a
slow rate to announce that a PCI data bus vehicle speed message from the Powertrain Control
Module (PCM) indicates that the vehicle speed is over a programmed speed value. This feature is
only enabled on a CTM that has been programmed with a Middle East Gulf Coast Country (GCC)
country code.
- Warning Chime Support - The CTM chime tone generator will generate repetitive chime tones at a
slow rate to announce that a PCI data bus chime request message input has been received from
the EMIC or the Airbag Control Module (ACM). These chime tones provide an audible alert to the
vehicle operator that supplements certain visual indications displayed by the EMIC. Supplemented
indications include the following:
- The "Airbag" indicator is illuminated. The ACM sends a chime request to the CTM at the same
time it sends an airbag lamp-ON request to the EMIC. The chimes will continue to sound for a
duration of about four seconds each time the indicator is illuminated or until the ignition switch is
turned to the OFF position, whichever occurs first.
- The "Check Gages" indicator is illuminated. The EMIC sends a chime request to the CTM. The
chimes will continue to sound for a duration of about two seconds each time the indicator is
illuminated or until the ignition switch is turned to the OFF position, whichever occurs first.
- The "Low Fuel" indicator is illuminated. The EMIC sends a chime request to the CTM. The chimes
will continue to sound for a duration of about two seconds each time the indicator is illuminated or
until the ignition switch is turned to the OFF position, whichever occurs first.
- The "Low Wash" indicator is illuminated. The EMIC sends a chime request to the CTM. The
chimes will continue to sound for a duration of about two seconds each time the indicator is
illuminated or until the ignition switch is turned to the OFF position, whichever occurs first.
- The "Trans Temp" indicator is illuminated (automatic transmission only). The EMIC sends a chime
request to the CTM. The chimes will continue to sound for a duration of about two seconds each
time the indicator is illuminated or until the ignition switch is turned to the OFF position, whichever
occurs first.
- A turn signal indicator is illuminated after the vehicle has surpassed a programmed speed and
distance. The EMIC sends a chime request to the CTM. The chimes will continue to sound until the
turn signal is turned OFF, or until the vehicle speed is reduced below the programmed level,
whichever occurs first.
The CTM provides chime service for all available features in the chime warning system. The CTM
relies upon its internal programming and hard wired inputs from the door ajar switches, the
headlamp switch, and the key-in ignition switch (ignition switch) to provide chime service for the
head/park/courtesy lights-on reminder, the key-in ignition reminder, and the door ajar warning. The
CTM relies upon electronic message inputs received from other electronic modules over the PCI
data bus network to provide chime service for all of the remaining chime warning system features.
Upon receiving the proper inputs, the CTM activates the integral chime tone generator to provide
the audible chime tone to the vehicle operator. The chime tone generator in the CTM is capable of
producing a single short beep and repeated chime tones at two different rates, slow and fast. The
slow chime rate is about 50 chime tones per minute, while the fast chime rate is about 180 chime
tones per minute.
The slow chime rate, 50 chimes per minute, is for reminders while the fast chime rate, 180 chimes
per minute, is for serious conditions that require immediate attention. The high rate chime sounds
when the key is left in the ignition and the driver's door is open or if the headlights or the courtesy
lights are left on. The low rate chime sounds for any of the other conditions. There is a variable rate
feature that allows the chime to sound continuously for key-in and headlamp warning as long as
the door is open. The seat belt warning chime is activated for six seconds, and all other chime
conditions will activate the chime once at the same time the warning light on the cluster is
illuminated.
The Chime will sound for the following conditions: Ignition OFF key in ignition, driver's door open
- Ignition OFF, headlamps ON, driver's door open
- Ignition OFF, courtesy lamps ON, driver's door open
- Seat belt warning (after prove-out)
- Malfunction Indicator lamp (MIL) illuminated (after prove-out)
- Airbag lamp illuminated (after prove-out)
- Check gauges lamp
- Low fuel warning
- Low washer fluid lamp
- Door ajar warning
- Transmission temperature lamp
- Turn signal on reminder warning
- Button pushed on compass mini-trip computer
The hard wired chime warning system inputs to the CTM, as well as other hard wired circuits for
this system may be diagnosed and tested using conventional diagnostic tools and procedures. See
the owner's manual in the vehicle glove box for more information on the features provided by the
chime warning system.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Fig. 1 Central Timer Module
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
The high-line Central Timer Module (CTM) can also control some features of the audio system
when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A
high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a
chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless
entry module, and a vehicle theft security
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Audible Warning Device Control Module >
Component Information > Diagrams > Page 7249
system module in a single unit.
The high-line CTM also controls and integrates many of the additional electronic functions and
features included on models with this option. The RAZ radio receiver with a remote radio switch
option is one of the features that the CTM controls. The CTM is programmed to send switch status
messages over the J185O data bus to control the volume, seek, and pre-set station advance
functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches
located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch
status messages to the radio receiver. The electronic circuitry within the radio receiver responds to
the switch status messages it receives by adjusting the radio settings as requested.
In addition, radio receivers connected to the J1850 data bus have several audio system functions
that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more
information on DRB testing of the audio systems.
Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and
a high-line version. Whichever version of the CTM the vehicle is equipped with, it is concealed
behind the trim on the left cowl side inner panel below the instrument panel, where it is secured
with three screws. The CTM is enclosed in a molded plastic housing with three integral external
connector receptacles that connect it to the vehicle electrical system through one take out and
connector of the body wire harness, and two take outs and connectors of the instrument panel wire
harness. The base version of the CTM is used on base models of this vehicle. These base models
are not equipped with the optional power lock system, the Remote Keyless Entry (RKE) system,
the rear wiper system, the Vehicle Theft Security System (VTSS), or the remote radio controls. The
high-line version of the CTM is used on high-line vehicles that are equipped with one or more of
those options not found on base models.
The CTM utilizes integrated circuitry and information carried on the Programmable
Communications Interface (PCI) data bus network along with many hard wired inputs to monitor
many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal
circuitry and programming of the CTM allow it to supply the vehicle occupants with audible and
visual information, and to control and integrate many electronic functions and features of the
vehicle through both hard wired outputs and the transmission of electronic message outputs to
other electronic modules in the vehicle over the PCI data bus. The features that the CTM supports
or controls include the following: Automatic Door Lock - The high-line CTM provides an automatic door lock feature (also known as
rolling door locks). This is a programmable feature.
- Battery Protection - The CTM provides a battery saver feature that performs timed load shedding
whenever courtesy, reading, visor vanity, center console, glove box, or any exterior lamps are left
on with the ignition switch in the OFF position.
- Central Locking - The high-line CTM on vehicles equipped with the optional Vehicle Theft Security
System (VTSS) includes a central locking/ unlocking feature.
- Chimes - All versions of the CTM provide chime service and beep request service through an
integral chime tone generator.
- Door Lock Inhibit - The high-line CTM provides a power door lock inhibit feature.
- Enhanced Accident Response - The high-line CTM provides an optional enhanced accident
response feature. This is a programmable feature.
- Exterior Light Features - The CTM provides control of park lamps, fog lamps, and headlamps.
This includes support for optical horn (also known as flash-to-pass), headlamp time delay, daytime
running lamps (DRL - Canada only), and battery saver features.
- Interior Light Features - The CTM provides control of courtesy lamps, dome lamps, and the liftgate lamp. This includes support for a timed illuminated entry with fade-to-OFF, interior lighting
delay, courtesy illumination defeat, and battery saver features.
- Intermittent Wipe Control - The CTM provides control of the intermittent wipe delay, and
wipe-after-wash features for the front wiper and washer system. The high-line CTM also provides
these same features for the optional rear wiper and washer system.
- Panic Mode - The high-line CTM provides support for the optional RKE system panic mode
including horn chirp, headlamp flash, and park lamp flash features.
- Power Lock Control - The high-line CTM provides the optional power lock system features,
including support for the automatic door lock and door lock inhibit modes.
- Programmable Features - The CTM provides support for certain programmable features.
- Remote Keyless Entry - The high-line CTM provides the optional Remote Keyless Entry (RKE)
system features, including support for the RKE Lock (with optional horn chirp and park lamps
flash), Unlock (with optional park lamps flash, driver-door- only unlock, and unlock-all-doors),
Panic, and illuminated entry modes, as well as the ability to be programmed to recognize up to four
RKE transmitters. The RKE horn chirp, park lamps flash, driver- door-only unlock, and
unlock-all-doors features are programmable.
- Remote Radio Switch Interface - The high- line CTM monitors and transmits the status of the
optional remote radio switches on the steering wheel.
- Speed Sensitive Intermittent Wipe Control - The CTM provides a speed sensitive front intermittent
wipe feature.
- Vehicle Theft Security System - The high-line CTM provides control of the optional Vehicle Theft
Security System (VTSS) features, including support for the central locking/unlocking mode and
control of the Security indicator in the instrument cluster.
Hard wired circuitry connects the CTM to the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained
by many different methods. These circuits may be connected to each other, to the vehicle electrical
system and to the CTM through the use of a combination of soldered splices, splice block
connectors, and many different types of wire harness terminal connectors and insulators.
All versions of the CTM for this model are serviced only as a complete unit. Many of the electronic
features in the vehicle controlled or supported by the CTM are programmable using the DRB III
scan tool. In addition, the CTM software is Flash compatible, which means it can be reprogrammed
using Flash reprogramming procedures. However, if any of the CTM hardware components are
damaged or faulty, the entire CTM unit must be replaced. The hard wired inputs or outputs of all
CTM versions can be diagnosed using conventional diagnostic tools and methods; however, for
diagnosis of the CTM or the PCI data bus, the use of a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

Component Information > Diagrams > Page 7250
The microprocessor-based Central Timer Module (CTM) monitors many hard wired switch and
sensor inputs as well as those resources it shares with other electronic modules in the vehicle
through its communication over the Programmable Communications Interface (PCI) data bus
network. The internal programming and all of these inputs allow the CTM microprocessor to
determine the tasks it needs to perform and their priorities, as well as both the standard and
optional features that it should provide. The CTM programming then performs those tasks and
provides those features through both PCI data bus communication with other electronic modules
and through hard wired outputs through a number of driver circuits, relays, and actuators. These
outputs allow the CTM the ability to control numerous accessory systems in the vehicle.
The CTM operates on battery current received through two fuses in the Junction Block (JB) on two
non-switched fused B(+) circuits, a fused ignition switch output (run-start) circuit, and a fused
ignition switch output (run-acc) circuit. This arrangement allows the CTM to provide some features
regardless of the ignition switch position, while other features will operate only with the ignition
switch in the Accessory, ON, and/or Start positions. The CTM receives ground through its
connector and take out of the instrument panel wire harness on three separate ground circuits. Two
of these circuits are grounded through a take out of the instrument panel wire harness with an
eyelet terminal connector that is secured by a nut to a ground stud on the left inner cowl side panel
near the CTM, while the third circuit is grounded through a take out of the instrument panel wire
harness with an eyelet terminal connector that is secured by a ground screw to the left side of the
floor panel transmission tunnel near the Airbag Control Module (ACM).
The CTM monitors its own internal circuitry as well as many of its input and output circuits, and will
store a Diagnostic Trouble Code (DTC) in electronic memory for any failure it detects. These DTCs
can be retrieved and diagnosed using a DRB III scan tool. Refer to the appropriate diagnostic
information.

Computers and Control Systems / Body Control Module. See: Body and Frame/Body Control
Systems/Central Timer Module
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.

Brake Warning Indicator: Description and Operation
BRAKE/PARK BRAKE INDICATOR
A brake indicator is standard equipment on all instrument clusters. The brake indicator is located in
the Information Center area of the instrument cluster; to the right of center. The brake indicator
consists of a stenciled cutout of the word "BRAKE" and the International Control and Display
Symbol icons for "Brake Failure" and "Parking Brake" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the
"BRAKE" text and the two icons to appear in red through the translucent outer layer of the overlay
when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied, or
when there are certain brake hydraulic system malfunctions. This indicator is controlled by a
transistor on the instrument cluster circuit board based upon cluster programming, and electronic
messages received by the cluster from the Central Timer Module (CTM) and the Controller Antilock
Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The brake
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the brake indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the brake indicator is
illuminated by the instrument cluster for about four seconds as a bulb test.
- Brake Lamp-On Message - Each time the cluster receives a lamp-on message from the CTM or
the CAB, the brake indicator will be illuminated. If the park brake is applied or not fully released, or
if the pressures in the two halves of the split brake hydraulic system are not equal with the ignition
switch in the ON position, the brake indicator is illuminated solid. The brake indicator will blink ON
and OFF repeatedly when the park brake is applied or not fully released and the ignition switch is in
the ON position if the automatic transmission is not in Park or Neutral. The indicator remains
illuminated until the cluster receives lamp-off messages from both the CTM and the CAB, or until
the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the CTM circuitry through the park brake switch sense circuit whenever the park brake is applied or
not fully released. The CTM then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. The brake pressure switch on the brake combination valve provides a hard
wired ground input to the CAB circuitry through the brake pressure switch sense circuit whenever
the pressures in the two halves of the split brake hydraulic system are unequal. The CAB then
sends the proper lamp-ON or lamp-OFF messages to the instrument cluster. If the CAB sends a
lamp-ON message after the bulb test, it indicates that the CAB has detected a brake hydraulic
system malfunction and/or that the ABS system has become inoperative. The CAB will store a
Diagnostic Trouble Code (DTC) for any malfunction it detects. The park brake switch input to the
CTM and the brake pressure switch input to the CAB can be diagnosed using conventional
diagnostic tools and methods. For proper diagnosis of the antilock brake system, the CTM, the
CAB, the PCI data bus, or the message inputs to the instrument cluster that control the brake
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Check Gauges Lamp: Description and Operation
A check gauges indicator is standard equipment on all instrument clusters. The check gauges
indicator is located in the Information Center area of the instrument cluster, to the right of center.
The check gauges indicator consists of a stenciled cutout of the words "CHECK GAGES" in the
opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents the
indicator from being clearly visible when it is not illuminated. A red lens behind the cutout in the
opaque layer of the overlay causes the "CHECK GAGES" text to appear in red through the
translucent outer layer of the overlay when the indicator is illuminated from behind by a Light
Emitting Diode (LED) soldered onto the instrument cluster electronic circuit board. The check
gauges indicator is serviced as a unit with the instrument cluster.
The check gauges indicator gives an indication to the vehicle operator when certain instrument
cluster gauge readings reflect a condition requiring immediate attention. This indicator is controlled
by a transistor on the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The check gauges indicator Light
Emitting Diode (LED) receives battery current on the instrument cluster electronic circuit board
through the fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON
or Start positions; therefore, the LED will always be OFF when the ignition switch is in any position
except ON or Start. The LED only illuminates when it is provided a path to ground by the
instrument cluster transistor. The instrument cluster will turn ON the check gauges indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the check gauges indicator is
illuminated for about two seconds as a bulb test.
- Engine Temperature High Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is about 122 °C (253 °F) or higher, the check gauges
indicator will be illuminated. The indicator remains illuminated until the cluster receives a message
from the PCM indicating that the temperature is about 119 °C (246 °F) or lower, or until the ignition
switch is turned to the OFF position, whichever occurs first.
- Engine Oil Pressure Low Message - Each time the cluster receives a message from the PCM
indicating the engine oil pressure is about 3.45 kPa (0.5 psi) or lower, the check gauges indicator
will be illuminated. The indicator remains illuminated until the cluster receives a message from the
PCM indicating that the engine oil pressure is above 3.45 kPa (0.5 psi), or until the ignition switch is
turned to the OFF position, whichever occurs first. The cluster will only turn the indicator ON in
response to an engine oil pressure low message if the engine speed is greater than zero.
- System Voltage Low Message - Each time the cluster receives a message from the PCM
indicating the electrical system voltage is less than 11.5 volts, the check gauges indicator will be
illuminated. The indicator remains illuminated until the cluster receives a message from the PCM
indicating the electrical system voltage is greater than 12.0 volts (but less than 16.6 volts), or until
the ignition switch is turned to the OFF position, whichever occurs first.
- System Voltage High Message - Each time the cluster receives a message from the PCM
indicating the electrical system voltage is greater than 16.6 volts, the check gauges indicator will be
illuminated. The indicator remains illuminated until the cluster receives a message from the PCM
indicating the electrical system voltage is less than 16.1 volts (but greater than 11.5 volts), or until
the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the engine temperature, oil pressure, and electrical system voltage,
then sends the proper messages to the instrument cluster. For further diagnosis of the check
gauges indicator or the instrument cluster circuitry that controls the LED, (Refer to
ELECTRICAL/INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of
the PCM, the PCI data bus, or the message inputs to the instrument cluster that control the check
gauges indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Cigarette Lighter: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem

Fig.6 Electrostatic Discharge Symbol
STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES
All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When
handling any component with this symbol, comply with the following procedures to reduce the
possibility of electrostatic charge build up on the body and inadvertent discharge into the
component. If it is not known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part form
it's protective packing until it is time to install the part. 5. Before removing the part from it's
package, ground the package to a known good ground on the vehicle.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Compass: Description and Operation
COMPASS/MINI-TRIP COMPUTER
The Compass/Mini-Trip Computer is located in the overhead console on models equipped with this
option. The compass mini-trip computer units include the electronic control module, a
Vacuum-Fluorescent Display (VFD), a compass sensor unit and two push button function switches.
The Compass/Mini-Trip Computer module contains a central processing unit and interfaces with
other electronic modules in the vehicle on the Programmable Communication Interface (J1850)
data bus network. The J1850 data bus network allows the sharing of sensor information. This helps
to reduce wire harness complexity, reduce internal controller hardware, and reduce component
sensor current loads. At the same time, this system provides increased reliability, enhanced
diagnostics, and allows the addition of many new feature capabilities.
The Compass/Mini-Trip Computer provides several electronic functions and features. Some of the
functions and features that the compass mini-trip computer module supports and/or controls,
include the following display options: Compass and Temperature - provides the outside temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
- Trip Odometer (ODO) - shows the distance travelled since the last trip computer reset.
- Average Fuel Economy (AVG ECO) - shows the average fuel economy since the last trip
computer reset.
- Instant Fuel Economy (ECO) - shows the present fuel economy based upon the current vehicle
distance and fuel used information.
- Distance To Empty (DTE) - shows the estimated distance that can be travelled with the fuel
remaining in the fuel tank. This estimated distance is computed using the average miles-per-gallon
from the last 30 gallons of fuel used.
- Elapsed Time (ET) - shows the accumulated ignition-on time since the last trip computer reset.
- Blank Screen - the compass mini-trip VFD is turned OFF.
The Compass/Mini-Trip Computer uses two push buttons to toggle the display and reset various
functions. These push buttons include: Step Button - Press this button to cycle through all the mini-trip computer displays.
- US/M Button - Press this button to convert all vehicle displays from US to Metric to US.
The Compass/Mini-Trip Computer module cannot be repaired, and is available for service only as a
unit. This unit includes the push button switches and the plastic module and display lens. If any of
these components is faulty or damaged, the complete compass mini-trip computer module must be
replaced.
To Reset the Display
Press the Step and US/M buttons simultaneously for at least two seconds and all resettable
conditions will be reset. This will occur only if a resettable function (AVG ECO, ECO, ET) is
currently being displayed.
Ambient Temperature Sensor
The ambient temperature sensor is hard wired to the HVAC control head. Data input for all other
Compass/Mini-Trip Computer functions, including VFD dimming level, is received through J1850
data bus messages. The Compass/Mini-Trip Computer uses its internal programming and all of
these inputs to calculate and display the requested data. If the data displayed is incorrect, perform
the self-diagnostic tests. If these tests prove inconclusive, the use of a DRB scan tool and the
proper Diagnostic Procedures are recommended for further testing of the compass mini-trip
computer module and the J1850 data bus.
COMPASS
While in the compass/temperature mode, the compass will display the direction in which the vehicle
is pointed using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle in three complete circles, on level ground, in not less than
48 seconds. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized, the demagnetizing and calibration
procedures found may be required to restore proper compass operation.
The Compass/Mini-Trip Computer only operates with the ignition switch in the ON position. When
the ignition switch is turned to the ON position, all of the segments in the Compass/Mini-Trip
Computer VFD will be turned OFF for one second, then the display will return to the last function
being displayed before the ignition was turned to the OFF position. With the ignition switch in the
ON position, momentarily depressing and releasing the Step push button switch will cause the
Compass/Mini-Trip Computer to change its mode of operation, and momentarily depressing and
releasing the U.S./Metric push button will cause the unit to toggle between U.S. and Metric
measurements. This Compass/Mini-Trip Computer features several functions that can be reset. If
both the Step and U.S/Metric push buttons are depressed at the same time for more than one
second with the ignition switch in the ON position, the trip computer information that can be reset is
reset. However, the reset will only occur if the function currently displayed is a function that can be
reset. The functions that can be reset are: TRIP ODO, AVG ECO, and ET.
For more information on the features and control functions of the Compass/Mini-Trip Computer,
see the owner's manual in the vehicle glove box.

Automatic Compass Calibration
This compass is self calibrating which eliminates the need to manually set the compass. When the
vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. After
completing three 360' turns in an area free from large metal or metallic objects, the CAL symbol will
turn OFF and the compass will function normally.
Compass Variance
Compass Variance is the difference between Magnetic North and Geographic North. In some areas
of the country, the difference between Magnetic and Geographic North is great enough to cause
the compass to give false readings. If this occurs, the compass variance must be set.
To Set The Variance
Turn the ignition ON and set display to Comp./Temp. while pressing the US/M button, press the
STEP button for approximately five seconds. The "VAR" symbol will light and the last variance
zone number will be displayed. Press the US/Metric Button to select the proper variance zone as
shown on the map. Press the Step button to set the new variance zone and resume normal
operation.
THERMOMETER
The thermometer displays the outside ambient temperature in whole degrees. The temperature
display can be changed from Fahrenheit to Celsius using the U.S./Metric push button. The
displayed temperature is not an instant reading of conditions, but an average temperature. It may
take the thermometer display several minutes to respond to a major temperature change, such as
driving out of a heated garage into winter temperatures.
When the ignition switch is turned to the OFF position, the last displayed temperature reading stays
in the thermometer unit memory. When the ignition switch is turned to the ON position again, the
thermometer will display the memory temperature if the engine coolant temperature is above about
52 °C (125 °F). If the engine coolant temperature is below about 52 °C (125 °F), the thermometer
will display the actual temperature sensed by the ambient temperature sensor. The thermometer
temperature display update interval varies with the vehicle speed.
The thermometer function is supported by an ambient temperature sensor. The sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the HVAC control head which sends temperature on J1850 data bus circuit. The ambient
temperature sensor is available as a separate service item.
NOTE: The compass mini-trip computer will display "OC" for temperatures below -40 °C and "SC"
for temperatures above 55 °C.

Compass: Testing and Inspection
If the problem with the compass mini-trip computer module is an "OC" or "SC" in the
compass/thermometer display, refer to Ambient Temperature Sensor in the Diagnosis and Testing.
If the problem with the compass mini-trip computer module is an inaccurate or scrambled display,
refer to Self-Diagnostic Test in the Diagnosis and Testing. If the problem with the compass mini-trip
computer module is incorrect Vacuum Fluorescent Display (VFD) dimming levels, use a DRB scan
tool and the proper Diagnostic Procedures to test for the correct dimming message inputs being
received from the instrument cluster over the J1850 data bus. If the problem is a no-display
condition, use the following procedures.
1. Check the fused ignition switch output (run/start) fuse in the junction block. If OK, go to Step 2. If
not OK, repair the shorted circuit or component
as required and replace the faulty fuse.
2. Turn the ignition switch to the ON position. Check for battery voltage at the fused ignition switch
output (run/start) fuse in the junction block. If
OK, go to Step 3. If not OK, repair the open fused ignition switch output (run/start) circuit to the
ignition switch as required.
3. Turn the ignition switch to the OFF position. Disconnect and isolate the battery negative cable.
Remove the overhead console. Check for
continuity between the ground circuit cavities of the roof wire harness connector for the overhead
console and a good ground. There should be continuity. If OK, go to Step 4. If not OK, repair the
open ground circuit to ground as required.
4. Connect the battery negative cable. Turn the ignition switch to the ON position. Check for battery
voltage at the fused ignition switch output
(run/start) circuit cavity of the roof wire harness connector for the overhead console. If OK, refer to
Self-Diagnostic Test in the Diagnosis and Testing for further diagnosis of the compass mini-trip
computer module and the J1850 data bus. If not OK, repair the open fused ignition switch output
(run/start) circuit to the junction block fuse as required.
Self-Check Diagnostics
A self-diagnostic test is used to determine that the compass mini-trip computer module is operating
properly electrically. Initiate the self-diagnostic test as follows: 1. With the ignition switch in the OFF
position, simultaneously depress and hold the Step button and the U.S./Metric button while rotating
the
ignition switch to the ON position..
2. Continue to hold both buttons depressed until the compass mini-trip computer module enters the
display segment test. In this test, all of the
Vacuum Fluorescent Display (VFD) segments are lighted while the compass mini-trip computer
module performs the following checks: Non-Volatile Memory Test (EEPROM)
- Asic Communications Test
- Vref Voltage Test.
- Compass Test
- J1850 Communications Test
3. Following completion of these tests, the compass mini-trip computer will return to normal
operation or display one of two messages: "FML" or
"BUS." Respond to these test results as follows: If no test result message is displayed, but compass mini-trip computer operation is still improper,
the use of a DRB scan tool and the proper Diagnostic Procedures are required for further
diagnosis.
- If the "FAIL" message is displayed, the compass mini-trip computer module is faulty and must be
replaced.
- If the "BUS" message is displayed, one or more of the required J1850 messages are not present
(see list below) and the use of a DRB scan tool and the proper Diagnostic Procedures are required
for further diagnosis.
- If any VFD segment should fail to light during the display segment test, the compass mini-trip
computer module is faulty and must be replaced.
4. If the first five tests pass, the Compass mini- trip computer shall verify that all the required J1850
messages are present on the J1850 bus. If all
required J1850 messages are present on the J1850 bus, or if the ignition switch is turned to the
OFF position, the compass mini-trip computer module will automatically return to normal operation.
The required J1850 messages are: Dimming message
- Fuel Used message
- Distance Pulses message
- Percentage Fuel Tank Full message
- Fuel Type message
- VIN (Vehicle Identification Number)
- Vehicle Speed message
- Engine gauge data (Coolant temperature data)
NOTE: The Fuel Used J1850 message shall be ignored if the engine type is Diesel or Compressed Natural
Gas.
- Pressing the STEP or US/M switches during any portion of the testing procedure will cause the
compass mini-trip computer to exit diagnostics and return to compass/temperature mode.
- If the compass functions, but accuracy is suspect, it may be necessary to perform a variation
adjustment. This procedure allows the compass unit to accommodate variations in the earth's
magnetic field strength, based on geographic location. Refer to Compass Variation Adjustment in
the Service Procedures.
- If the compass reading has blanked out, and only "CAL" appears in the display, demagnetizing
may be necessary to remove excessive residual magnetic fields from the vehicle. Refer to
Compass Demagnetizing in the Service Procedures.

Compass: Adjustments
Compass variance, also known as magnetic declination, is the difference in angle between
magnetic north and true geographic north. In some geographic locations, the difference between
magnetic and geographic north is great enough to cause the compass to give false readings. If this
problem occurs, the compass variance must be set.
Fig. 1 Variance Settings
To set the compass variance:
1. Using the Variance Settings map, find your geographic location and note the zone number (Fig.
1). 2. Turn the ignition switch to the ON position. If the compass/temperature data is not currently
being displayed, momentarily depress and release the
Step push button to step through the display options until you have reached the
compass/temperature display.
3. Depress both the U.S./Metric, and the Step push buttons and hold the buttons down until "WAR"
appears in the display. This takes about five
seconds.
4. Release both of the push buttons. "WAR" along with the current variance zone will appear in the
display. 5. Momentarily depress and release the U.S./Metric push button to step through the zone
numbers, until the zone number for your geographic
location appears in the display.
6. Momentarily depress and release the Step push button to enter the displayed zone number into
the compass unit memory. 7. Confirm that the correct directions are now indicated by the compass.

Compass: Service and Repair Compass Calibration
CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the
vicinity of the compass. Do not use magnetic tools when servicing the overhead console.
The electronic compass unit features a self-calibrating design, which simplifies the calibration
procedure. This feature automatically updates the compass calibration while the vehicle is being
driven. This allows the compass unit to compensate for small changes in the residual magnetism
that the vehicle may acquire during normal use. If the compass readings appear to be erratic or out
of calibration, perform the following calibration procedure. Also, new service replacement compass
mini-trip computer modules must have their compass calibrated using this procedure. Do not
attempt to calibrate the compass near large metal objects such as other vehicles, large buildings,
or bridges; or, near overhead or underground power lines.
NOTE: Whenever the compass is calibrated manually, the variation number must also be reset.
See Compass Variation Adjustment in the Service Procedures.
Calibrate the compass manually as follows:
1. Turn the ignition switch to the ON position. If the compass/temperature data is not currently
being displayed, momentarily depress and release the
Step push button to step through the display options until you have reached the
compass/temperature display.
2. Depress both the U.S./Metric and the Step push buttons. Hold the push buttons down until "CAL"
appears in the display. This takes about ten
seconds, and appears about five seconds after 'WAR" is displayed.
3. Release both of the push buttons. 4. Drive the vehicle on a level surface, away from large metal
objects and power lines, through three or more complete circles in not less than 48
seconds. The "CAL" message will disappear from the display to indicate that the compass is now
calibrated.
NOTE: If the "CAL" message remains in the display, either there is excessive magnetism near the
compass, or the unit is faulty. Repeat the calibration procedure at least one more time.
- If the wrong direction is still indicated in the compass display, the area selected for calibration
may be too close to a strong magnetic field. Repeat the calibration procedure in another location.

Compass: Service and Repair Compass Demagnetizing
A degaussing tool (Special Tool 6029) is used to demagnetize, or degauss, the overhead console
forward mounting screw and the roof panel above the overhead console. Equivalent units must be
rated as continuous duty for 110/115 volts and 60 Hz. They must also have a field strength of over
350 gauss at 7 millimeters (0.25 inch) beyond the tip of the probe.
To demagnetize the roof panel and the overhead console forward mounting screw, proceed as
follows:
1. Be certain that the ignition switch is in the OFF position, before you begin the demagnetizing
procedure. 2. Connect the degaussing tool to an electrical outlet, while keeping the tool at least 61
centimeters (2 feet) away from the compass unit. 3. Slowly approach the head of the overhead
console forward mounting screw with the degaussing tool connected. 4. Contact the head of the
screw with the plastic coated tip of the degaussing tool for about two seconds. 5. With the

Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Cruise Control Indicator Lamp >
Component Information > Description and Operation
Cruise Control Indicator Lamp: Description and Operation
A cruise indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with the optional speed control system, this indicator is electronically disabled. The cruise
indicator consists of the word "CRUISE", which appears in the lower portion of the odometer/trip
odometer Vacuum-Fluorescent Display (VFD). The VFD is part of the cluster electronic circuit
board, and is visible through a cutout located in the lower left corner of the cluster overlay. The
dark lens of the VFD prevents the indicator from being clearly visible when it is not illuminated. The
word "CRUISE" appears in an amber color and at the same lighting level as the odometer/trip
odometer information when it is illuminated by the instrument cluster electronic circuit board. The
cruise indicator is serviced as a unit with the VFD in the instrument cluster.
The cruise indicator gives an indication to the vehicle operator when the speed control system is
turned ON, regardless of whether the speed control is engaged. This indicator is controlled by the
instrument cluster circuit board based upon cluster programming and electronic messages received
by the cluster from the Powertrain Control Module (PCM) over the Programmable Communications
Interface (PCI) data bus. The cruise indicator receives battery current ON the instrument cluster
electronic circuit board through the fused ignition switch output (run-start) circuit whenever the
ignition switch is in the ON or Start positions; therefore, the indicator will always be OFF when the
ignition switch is in any position except ON or Start. The indicator only illuminates when it is
switched to ground by the instrument cluster circuitry. The instrument cluster will turn ON the cruise
indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the cruise indicator is
illuminated for about two seconds as a bulb test.
- Cruise Lamp-ON Message - Each time the cluster receives a cruise lamp-ON message from the
PCM indicating the speed control system has been turned ON, the cruise indicator is illuminated.
The indicator remains illuminated until the cluster receives a cruise lamp-OFF message from the
PCM or until the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the cruise indicator will be
turned ON, then OFF again during the VFD portion of the test to confirm the functionality of the
VFD, and again during the bulb check portion of the test to confirm the functionality of the cluster
control circuitry.
The PCM continually monitors the speed control switches to determine the proper outputs to the
speed control servo. The PCM then sends the proper cruise indicator lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the cruise indicator or the instrument
cluster circuitry that controls the indicator, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND
TESTING). For proper diagnosis of the speed control system, the PCM, the PCI data bus, or the
message inputs to the instrument cluster that control the cruise indicator, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.

Door/Trunk Ajar Indicator/Lamp: Description and Operation
DOOR AJAR INDICATOR
A door ajar indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with this optional feature, this indicator is electronically disabled. The door ajar indicator
is located in the Information Center area of the instrument cluster, to the left of center. The door
ajar indicator consists of a stenciled cutout of the words "DOOR AJAR" in the opaque layer of the
instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being
clearly visible when it is not illuminated. A red lens behind the cutout in the opaque layer of the
overlay causes the "DOOR AJAR" text to appear in red through the translucent outer layer of the
overlay when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto
the instrument cluster electronic circuit board. The door ajar indicator is serviced as a unit with the
instrument cluster.
The door ajar indicator gives an indication to the vehicle operator that one or more of the
passenger compartment doors may be open or not completely latched. This indicator is controlled
by a transistor on the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Central Timer Module (CTM) over the
Programmable Communications Interface (PCI) data bus. The door ajar indicator Light Emitting
Diode (LED) receives battery current on the instrument cluster electronic circuit board through the
fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions; therefore, the LED will always be OFF when the ignition switch is in any position except
ON or Start. The LED only illuminates when it is provided a path to ground by the instrument
cluster transistor. The instrument cluster will turn ON the door ajar indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the door ajar indicator is
illuminated for about two seconds as a bulb test.
- Door Ajar Lamp-ON Message - Each time the cluster receives a door ajar lamp-ON message
from the CTM indicating that a door is open or not completely latched, the door ajar indicator will be
illuminated. The indicator remains illuminated until the cluster receives an door ajar lamp-OFF
message from the CTM, or until the ignition switch is turned to the OFF position, whichever occurs
first.
- Actuator Test - Each time the cluster is put through the actuator test, the door ajar indicator will be
turned ON, then OFF again during the bulb check portion of the test to confirm the functionality of
the cluster control circuitry.
The CTM continually monitors the door ajar switches to determine the status of the doors. The
CTM then sends the proper door ajar lamp-on and lamp-off messages to the instrument cluster.
For further diagnosis of the door ajar indicator or the instrument cluster circuitry that controls the
indicator, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis
of the door ajar switches and circuits, (Refer to LAMPS/LIGHTING - INTERIOR/DOOR AJAR
SWITCH DIAGNOSIS AND TESTING). For proper diagnosis of the CTM, the PCI data bus, or the
message inputs to the instrument cluster that control the door ajar indicator, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.
LIFTGATE AJAR INDICATOR
A liftgate ajar indicator is standard equipment on all instrument clusters. However, on vehicles not
equipped with this optional feature, this indicator is electronically disabled. The liftgate ajar indicator
is located in the Information Center area of the instrument cluster, to the left of center. The liftgate
ajar indicator consists of a stenciled cutout of the words "GATE OPEN" in the opaque layer of the
instrument cluster overlay. The dark outer layer of the overlay prevents the indicator from being
clearly visible when it is not illuminated. A red lens behind the cutout in the opaque layer of the
overlay causes the "GATE OPEN" text to appear in red through the translucent outer layer of the
overlay when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto
the instrument cluster electronic circuit board. The liftgate ajar indicator is serviced as a unit with
the instrument cluster.
The liftgate ajar indicator gives an indication to the vehicle operator that the passenger
compartment liftgate may be open or not completely latched. This indicator is controlled by a
transistor on the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the Central Timer Module (CTM) over the Programmable
Communications Interface (PCI) data bus. The liftgate ajar indicator Light Emitting Diode (LED)
receives battery current on the instrument cluster electronic circuit board through the fused ignition
switch output (run-start) circuit whenever the ignition switch is in the ON or Start positions;
therefore, the LED will always be OFF when the ignition switch is in any position except ON or
Start. The LED only illuminates when it is provided a path to ground by the instrument cluster
transistor. The instrument cluster will turn ON the liftgate ajar indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the liftgate ajar indicator is
illuminated for about two seconds as a bulb test.
- Liftgate Ajar Lamp-ON Message - Each time the cluster receives a liftgate ajar lamp-ON message
from the CTM indicating that the liftgate is open or not completely latched, the liftgate ajar indicator
will be illuminated. The indicator remains illuminated until the cluster receives an liftgate ajar
lamp-OFF message from the CTM, or until the ignition switch is turned to the OFF position,
whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the liftgate ajar indicator will
be turned ON, then OFF again during the bulb check portion of the test to confirm the functionality
of the cluster control circuitry.
The CTM continually monitors the liftgate ajar switch to determine the status of the liftgate. The
CTM then sends the proper liftgate ajar lamp-ON and lamp-OFF messages to the instrument
cluster. For further diagnosis of the liftgate ajar indicator or the instrument cluster circuitry that
controls the indicator, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For
proper diagnosis of the liftgate ajar switch and circuits,

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool
Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.

Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each door. The switches close a path to
ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Driver/Vehicle Information Display: Description and Operation
OVERHEAD CONSOLE
An overhead console unit is an available factory-installed option on this model The overhead
console unit features a garage door opener storage bin, a sunglasses storage bin, two reading and
courtesy lamps and either a standard paperclip or an optional compass mini-trip computer. See the
owner's manual in the vehicle glove box for more information on the features, use and operation of
all of the overhead console components and systems.
The overhead console for this model includes two front-mounted reading and courtesy lamps, a
sunglasses storage bin, universal transmitter and either a standard paperclip or an optional
compass mini-trip computer.
The overhead console is secured with two snap clips at the rear and a single screw at the front to
the overhead console mounting bracket. The front of the overhead console mounting bracket is
secured to the roof header near the windshield with two screws, and the rear of the bracket is
secured with double-faced tape to the inside surface of the roof panel. A single electrical
connection joins the overhead console wire harness to the roof wire harness.
Following are general descriptions of the major components used in the overhead console. See the
owner's manual in the vehicle glove box for more information on the use and operation of the
various overhead console features.
Sunglass Storage Bin
A sunglasses storage bin is included in the overhead console. The storage bin is located near the
center of the overhead console and is held in the closed position by a spring-loaded latch
mechanism that is integral to the storage bin door. The interior of the bin is lined with a foam rubber
padding material to protect the sunglasses from being scratched. A damper spring is snapped onto
the pivot shaft of the sunglasses storage bin door. The damper spring engages two flats on the
shaft and is anchored in a slot in the rear flange of the overhead console reading and courtesy
lamp housing to provide a smooth opening action and an open detent position for the storage bin
unit.
The sunglasses storage bin and door unit is available for service replacement. The bin and door
unit includes the spring-loaded latch mechanism, the bin liner and the damper spring. If any of
these components is damaged or faulty, the sunglasses storage bin and door unit must be
replaced.
The sunglasses storage bin is opened by pressing the latch on the rear edge of the door towards
the front of the vehicle, then pulling the bin downward to the open detent position. The
spring4oaded latch mechanism on the sunglasses bin door will automatically engage when the bin
is closed. See the owner's manual in the vehicle glove box for more information on the use and
operation of the sunglasses storage bin.
Paperclip
A paperclip is standard equipment on the base version of the overhead console. The paperclip
provides a convenient place for storage and easy retrieval of notes, maps, toll tickets or stubs and
other paper items that may be required or desired while driving. The paperclip is located near the
front of the overhead console and is secured in the overhead console housing by four screws.
The paperclip is available for service replacement, but it cannot be adjusted or repaired. If the
paperclip is damaged or faulty it must be replaced.
COMPASS/MINI-TRIP COMPUTER
The compass mini-trip computer is located in the overhead console on models equipped with this
option. The compass mini-trip computer units include the electronic control module, a
Vacuum-Fluorescent Display (VFD), a compass sensor unit and two push button function switches.
The compass mini-trip computer module contains a central processing unit and interfaces with
other electronic modules in the vehicle on the Programmable Communication Interface (J1850)
data bus network. The J1850 data bus network allows the sharing of sensor information. This helps
to reduce wire harness complexity, reduce internal controller hardware, and reduce component
sensor current loads. At the same time, this system provides increased reliability, enhanced
diagnostics, and allows the addition of many new feature capabilities.
The compass mini-trip computer provides several electronic functions and features. Some of the
functions and features that the compass mini-trip computer module supports and/or controls,
include the following display options: Compass and temperature - provides the outside temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
- Trip Odometer (TRIP ODO) - shows the distance travelled since the last trip computer reset.
- Average fuel economy (AVG ECO) - shows the average fuel economy since the last trip computer
reset.
- Instant fuel economy (ECO) - shows the present fuel economy based upon the current vehicle
distance and fuel used information.
- Distance To Empty (DTE) - shows the estimated distance that can be travelled with the fuel
remaining in the fuel tank. This estimated distance is computed using the average miles-per-gallon
from the last 30 gallons of fuel used.
- Elapsed Time (ET) - shows the accumulated ignition-on time since the last trip computer reset.
- Blank screen - the compass mini-trip VFD is turned OFF.
The ambient temperature sensor is hard wired to the IWAC control head. Data input for all other
compass mini-trip computer functions, including VFD dimming level, is received through J1850
data bus messages. The compass mini-trip computer uses its internal programming and all of
these inputs to calculate and display the requested data. If the data displayed is incorrect, perform
the self-diagnostic tests. If these tests prove inconclusive, the use of a DRB scan tool and the
proper Diagnostic Procedures are recommended for further testing of the compass mini-trip
computer module and the J1850 data bus.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Driver/Vehicle Information Display >
Component Information > Technical Service Bulletins > Page 7355
The compass mini-trip computer module cannot be repaired, and is available for service only as a
unit. This unit includes the push button switches and the plastic module and display lens. If any of
these components is faulty or damaged, the complete compass mini-trip computer module must be
replaced.
Compass
While in the compass/temperature mode, the compass will display the direction in which the vehicle
is pointed using the eight major compass headings (Examples: north is N, northeast is NE). The
self-calibrating compass unit requires no adjusting in normal use. The only calibration that may
prove necessary is to drive the vehicle in three complete circles, on level ground, in not less than
forty-eight seconds. This will reorient the compass unit to its vehicle.
The compass unit also will compensate for magnetism the body of the vehicle may acquire during
normal use. However, avoid placing anything magnetic directly on the roof of the vehicle. Magnetic
mounts for an antenna, a repair order hat, or a funeral procession flag can exceed the
compensating ability of the compass unit if placed on the roof panel. Magnetic bit drivers used on
the fasteners that hold the overhead console assembly to the roof header can also affect compass
operation. If the vehicle roof should become magnetized, the demagnetizing and calibration
procedures found may be required to restore proper compass operation.
The compass mini-trip computer only operates with the ignition switch in the ON position. When the
ignition switch is turned to the ON position, all of the segments in the compass mini-trip computer
VFD will be turned OFF for one second, then the display will return to the last function being
displayed before the ignition was turned to the OFF position. With the ignition switch in the ON
position, momentarily depressing and releasing the Step push button switch will cause the
compass-mini-trip computer to change its mode of operation, and momentarily depressing and
releasing the U.S./Metric push button will cause the unit to toggle between U.S. and Metric
measurements. This compass mini-trip computer features several functions that can be reset. If
both the Step and U.S/Metric push buttons are depressed at the same time for more than one
second with the ignition switch in the On position, the trip computer information that can be reset is
reset. However, the reset will only occur if the function currently displayed is a function that can be
reset. The functions that can be reset are: TRIP ODO, AVG ECO, and ET.
For more information on the features and control functions of the compass mini-trip computer, see
the owner's manual in the vehicle glove box.
Thermometer
The thermometer displays the outside ambient temperature in whole degrees. The temperature
display can be changed from Fahrenheit to Celsius using the U.S./Metric push button. The
displayed temperature is not an instant reading of conditions, but an average temperature. It may
take the thermometer display several minutes to respond to a major temperature change, such as
driving out of a heated garage into winter temperatures.
When the ignition switch is turned to the OFF position, the last displayed temperature reading stays
in the thermometer unit memory. When the ignition switch is turned to the ON position again, the
thermometer will display the memory temperature if the engine coolant temperature is above about
52 °C (125 °F). If the engine coolant temperature is below about 52 °C (125 °F), the thermometer
will display the actual temperature sensed by the ambient temperature sensor. The thermometer
temperature display update interval varies with the vehicle speed.
The thermometer function is supported by an ambient temperature sensor. The sensor is mounted
outside the passenger compartment near the front and center of the vehicle, and is hard wired to
the HVAC control head which sends temperature on J1850 data bus circuit. The ambient
temperature sensor is available as a separate service item.
NOTE: The compass mini-trip computer will display "OC" for temperatures below -40 °C and "SC"
for temperatures above 55 °C.
AMBIENT TEMPERATURE SENSOR
Ambient air temperature is monitored by the compass mini-trip computer module through the
ambient temperature sensor. The ambient temperature sensor is a variable resistor mounted to a
bracket that is secured with a screw to the right side of the radiator yoke, behind the radiator grille
and in front of the engine compartment.
For complete circuit diagrams, refer to Overhead Console in the Contents of Wiring Diagrams. The
ambient temperature sensor cannot be adjusted or repaired and, if faulty or damaged, it must be
replaced.
The ambient temperature sensor is a variable resistor that operates on a five-volt reference signal
sent to it by the compass mini-trip computer module. The resistance in the sensor changes as
temperature changes, changing the temperature sensor signal circuit voltage to the compass
mini-trip computer module. Based upon the resistance in the sensor, the compass mini-trip
computer module senses a specific voltage on the temperature sensor signal circuit, which it is
programmed to correspond to a specific temperature.
UNIVERSAL TRANSMITTER
On some models a Universal Garage Door Opener (UGDO) transceiver is standard
factory-installed equipment. The UGDO transceiver is integral to the overhead console. The only
visible component of the UGDO are the three transmitter push buttons at the rear of the overhead
console. The three UGDO transmitter push buttons are identified with one, two or three raised
tactile bumps so that they be easily identified by sight or by feel.
Each of the three UGDO transmitter push buttons controls an independent radio transmitter
channel. Each of these three channels can be trained to transmit a different radio frequency signal
for the remote operation of garage door openers, motorized gate openers, home or Office lighting,
security systems or just about any other device that can be equipped with a radio receiver in the
286 to 399 MegaHertz (MHz) frequency range for remote operation. The UGDO is capable of
operating systems using either rolling code or non-rolling code technology.
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Driver/Vehicle Information Display >
Component Information > Technical Service Bulletins > Page 7356
The UGDO cannot be repaired, and is available for service only as a unit. This unit includes the
push button switches and the plastic module.
The UGDO operates on a non-switched source of battery current so the unit will remain functional,
regardless of the ignition switch position. For more information on the features, programming
procedures and operation of the UGDO, see the owner's manual in the vehicle glove box.

Fuel Gauge: Locations
The fuel gauge is located in the lower right quadrant of the instrument cluster, below the oil
pressure gauge.

Fuel Gauge: Description and Operation
A fuel gauge is standard equipment on all instrument clusters. The fuel gauge is located in the
lower right quadrant of the instrument cluster, below the oil pressure gauge. The fuel gauge
consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a
fixed 90 degree scale on the cluster overlay that reads left-to-right from E (or Empty) to F (or Full).
An International Control and Display Symbol icon for "Fuel" is located on the cluster overlay in the
center of the gauge directly above the hub of the gauge needle. An arrowhead pointed to the left
side of the vehicle is imprinted on the cluster overlay next to the "Fuel" icon in the fuel gauge to
provide the driver with a reminder as to the location of the fuel filler access. The fuel gauge
graphics are white against a black field except for a single red graduation at the low end of the
gauge scale, making them clearly visible within the instrument cluster in daylight. When illuminated
from behind by the panel lamps dimmer controlled cluster illumination lighting with the exterior
lamps turned ON, the white graphics appear blue-green and the red graphics appear red. The
orange gauge needle is internally illuminated. Gauge illumination is provided by replaceable
incandescent bulb and bulb holder units located on the instrument cluster electronic circuit board.
The fuel gauge is serviced as a unit with the instrument cluster.
The fuel gauge gives an indication to the vehicle operator of the level of fuel in the fuel tank. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The fuel gauge is an air core magnetic
unit that receives battery current on the instrument cluster electronic circuit board through the fused
ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start positions.
The cluster is programmed to move the gauge needle back to the low end of the scale after the
ignition switch is turned to the OFF position. The instrument cluster circuitry controls the gauge
needle position and provides the following features:
- Percent Tank Full Message - Each time the cluster receives a message from the PCM indicating
the percent tank full, the cluster programming applies an algorithm to calculate the proper gauge
needle position, then moves the gauge needle to the proper position on the gauge scale. The
algorithm is used to dampen gauge needle movement against the negative effect that fuel sloshing
within the fuel tank can have on accurate inputs from the fuel tank sending unit to the PCM.
- Less Than 12.5 Percent Tank Full Message - Each time the cluster receives messages from the
PCM indicating the percent tank full is 12.5 (one- eighth) or less for 10 consecutive seconds and
the vehicle speed is zero, or for 60 consecutive seconds and the vehicle speed is greater than
zero, the gauge needle is moved to the proper position on the gauge scale, the low fuel indicator is
illuminated, and a single chime tone is sounded. The low fuel indicator remains illuminated until the
cluster receives messages from the PCM indicating that the percent tank full is greater than 12.5
(one-eighth) for 10 consecutive seconds and the vehicle speed is zero, or for 60 consecutive
seconds and the vehicle speed is greater than zero, or until the ignition switch is turned to the OFF
position, whichever occurs first. The chime tone feature will only repeat during the same ignition
cycle if the low fuel indicator is cycled OFF and then on again by the appropriate percent tank full
messages from the PCM.
- Less Than Empty Percent Tank Full Message - Each time the cluster receives a message from
the PCM indicating the percent tank full is less than empty, the gauge needle is moved to the far
left (low) end of the gauge scale and the low fuel indicator is illuminated immediately. This
message would indicate that the fuel tank sender input to the PCM is a short circuit.
- More Than Full Percent Tank Full Message - Each time the cluster receives a message from the
PCM indicating the percent tank full is more than full, the gauge needle is moved to the far left (low)
end of the gauge scale and the low fuel indicator is illuminated immediately. This message would
indicate that the fuel tank sender input to the PCM is an open circuit.
- Message Failure - If the cluster fails to receive a percent tank full message, it will hold the gauge
needle at the last indication until a new message is received, or until the ignition switch is turned to
the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the fuel tank sending unit, then sends the proper messages to the
instrument cluster. For further diagnosis of the fuel gauge or the instrument cluster circuitry that
controls the gauge, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper
diagnosis of the fuel tank sending unit, the PCM, the PCI data bus, or the message inputs to the
instrument cluster that control the fuel gauge, a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
fuel pump module is located inside of fuel tank.

Fuel Gauge Sender: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To
test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump
module. Refer to Fuel Pump Module Removal/installation for procedures. Measure the resistance
across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6%.
With float in down position, resistance should be 270 ohms ± 6%.

Low Fuel Lamp/Indicator: Description and Operation
A low fuel indicator is standard equipment on all instrument clusters. The low fuel indicator is
located in the Information Center area of the instrument cluster overlay, to the left of center. The
low fuel indicator consists of a stenciled cutout of the International Control and Display Symbol icon
for "Fuel" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. An amber lens behind the
cutout in the opaque layer of the overlay causes the icon to appear in amber through the
translucent outer layer of the overlay when the indicator is illuminated from behind by a Light
Emitting Diode (LED) soldered onto the instrument cluster electronic circuit board. The low fuel
indicator is serviced as a unit with the instrument cluster.
The low fuel indicator gives an indication to the vehicle operator when the level of fuel in the fuel
tank becomes low. This indicator is controlled by a transistor on the instrument cluster circuit board
based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The low fuel indicator Light Emitting Diode (LED) receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the ON or Start positions; therefore, the LED will always be OFF when the
ignition switch is in any position except ON or Start. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn ON the low fuel
indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the indicator is illuminated
for about two seconds as a bulb test.
- Less Than 12.5 Percent Tank Full Message - Each time the cluster receives messages from the
PCM indicating the percent tank full is 12.5 (one-eighth) or less for 10 consecutive seconds and the
vehicle speed is zero, or for 60 consecutive seconds and the vehicle speed is greater than zero,
the low fuel indicator is illuminated and a single chime tone is sounded. The low fuel indicator
remains illuminated until the cluster receives messages from the PCM indicating that the percent
tank full is greater than 12.5 (one-eighth) for 10 consecutive seconds and the vehicle speed is zero,
or for 60 consecutive seconds and the vehicle speed is greater than zero, or until the ignition switch
is turned to the OFF position, whichever occurs first. The chime tone feature will only repeat during
the same ignition cycle if the low fuel indicator is cycled OFF and then ON again by the appropriate
percent tank full messages from the PCM.
- Less Than Empty Percent Tank Full Message - Each time the cluster receives a message from
the PCM indicating the percent tank full is less than empty, the low fuel indicator is illuminated
immediately. This message would indicate that the fuel tank sender input to the PCM is a short
circuit.
- More Than Full Percent Tank Full Message - Each time the cluster receives a message from the
PCM indicating the percent tank full is more than full, the low fuel indicator is illuminated
immediately. This message would indicate that the fuel tank sender input to the PCM is an open
circuit.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the fuel tank sending unit, then sends the proper messages to the
instrument cluster. For further diagnosis of the low fuel indicator or the instrument cluster circuitry
that controls the LED, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For
proper diagnosis of the fuel tank sending unit, the PCM, the PCI data bus, or the message inputs to
the instrument cluster that control the low fuel indicator, a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

Malfunction Indicator Lamp: Description and Operation
A Malfunction Indicator Lamp (MIL) is standard equipment on all instrument clusters. The MIL is
located in the Information Center area of the instrument cluster overlay, to the left of center. The
MIL consists of a stencilled cutout of the International Control and Display Symbol icon for "Engine"
in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents
the indicator from being clearly visible when it is not illuminated. An amber lens behind the cutout in
the opaque layer of the overlay causes the icon to appear in amber through the translucent outer
layer of the overlay when the indicator is illuminated from behind by a Light Emitting Diode (LED)
soldered onto the instrument cluster electronic circuit board. The MIL is serviced as a unit with the
instrument cluster.
The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the
Powertrain Control Module (PCM) has recorded a Diagnostic Trouble Code (DTC) for an On-Board
Diagnostics II (OBDII) emissions-related circuit or component malfunction. The MIL is controlled by
a transistor on the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the PCM over the Programmable Communications Interface
(PCI) data bus. The MIL Light Emitting Diode (LED) receives battery current on the instrument
cluster electronic circuit board through the fused ignition switch output (run-start) circuit whenever
the ignition switch is in the ON or Start positions; therefore, the LED will always be OFF when the
ignition switch is in any position except ON or Start. The LED only illuminates when it is provided a
path to ground by the instrument cluster transistor. The instrument cluster will turn ON the MIL for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the indicator is illuminated
for about seven seconds as a bulb test.
- PCM Lamp-ON Message - Each time the cluster receives a lamp-on message from the PCM, the
indicator will be illuminated. The indicator can be flashed ON and OFF, or illuminated solid, as
dictated by the PCM message. For some DTC's, if a problem does not recur, the PCM will send a
lamp-off message automatically. Other DTC's may require that a fault be repaired and the PCM be
reset before a lamp-OFF message will be sent. For more information on the PCM, and the DTC set
and reset parameters, (Refer to EMISSIONS CONTROL - OPERATION).
- Communication Error - If the cluster receives no lamp-on message from the PCM for twenty
seconds, the MIL is illuminated by the instrument cluster to indicate a loss of bus communication.
The indicator remains controlled and illuminated by the cluster until a valid lamp-ON message is
received from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON during the bulb check portion of the test to confirm the functionality of the LED and the cluster
control circuitry.
The PCM continually monitors the fuel and emissions system circuits and sensors to decide
whether the system is in good operating condition. The PCM then sends the proper lamp-ON or
lamp-OFF messages to the instrument cluster. If the instrument cluster turns ON the MIL after the
bulb test, it may indicate that a malfunction has occurred and that the fuel and emissions systems
may require service. For proper diagnosis of the fuel and emissions systems, the PCM, the PCI
data bus, or the message inputs to the instrument cluster that control the MIL, a DRB III scan tool is
required. Refer to the appropriate diagnostic information.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Odometer > Component Information >
Description and Operation
Odometer: Description and Operation
An odometer and trip odometer are standard equipment in all instrument clusters. The odometer
and trip odometer information are displayed in a common electronic Vacuum-Fluorescent Display
(VFD), which is visible through a small window cutout located in the left lower quadrant of the
cluster overlay. However, the odometer and trip odometer information are not displayed
simultaneously. The trip odometer reset switch on the instrument cluster circuit board toggles the
display between odometer and trip odometer modes by depressing the odometer/ trip odometer
switch knob that extends through the lower edge of the cluster lens, just right of the odometer VFD.
When the trip odometer information is displayed, the word "TRIP" is also illuminated in a green
color and at the same lighting level as the trip odometer information in the lower right corner of the
VFD. Both the odometer and the trip odometer information is stored in the instrument cluster
memory.
The odometer can display values up to 499,999 kilometers (499,999 miles). The odometer latches
at these values, and will not roll over to zero. The trip odometer can display values up to 999.9
kilometers (999.9 miles) before it rolls over to zero. The odometer display does not have a decimal
point and will not show values less than a full unit (kilometer or mile), the trip odometer display
does have a decimal point and will show tenths of a unit (kilometer or mile). The unit of measure
(kilometers or miles) for the odometer and trip odometer display is not shown in the VFD. The unit
of measure for the instrument cluster odometer/trip odometer is selected at the time that it is
manufactured, and cannot be changed. During daylight hours (exterior lamps OFF) the VFD is
illuminated at full brightness for clear visibility. At night (exterior lamps are ON) the VFD lighting
level is adjusted with the other cluster illumination lamps using the panel lamps dimmer
thumbwheel on the headlamp switch. However, a "Parade" mode position of the panel lamps
dimmer thumbwheel allows the VFD to be illuminated at full brightness while the exterior lamps are
turned ON during daylight hours. The VFD, the trip odometer switch, and the trip odometer switch
button are serviced as a unit with the instrument cluster.
The odometer and trip odometer give an indication to the vehicle operator of the distance the
vehicle has traveled. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) over the Programmable Communications Interface (PCI) data bus. The odometer
and trip odometer information is displayed by the instrument cluster Vacuum Fluorescent Display
(VFD), and the VFD will not display odometer or trip odometer information after the ignition switch
is turned to the OFF position. The instrument cluster circuitry controls the VFD and provides the
following features:
- Odometer/Trip Odometer Display Toggling - Actuating the trip odometer reset switch momentarily
with the ignition switch in the ON position will toggle the VFD between the odometer and trip
odometer display. Each time the ignition switch is turned to the ON position the VFD will
automatically return to the mode (odometer or trip odometer) last displayed when the ignition
switch was turned to the OFF position.
- Trip Odometer Reset - When the trip odometer reset switch is pressed and held for longer than
about two seconds, the trip odometer will be reset to 000.0 kilometers (miles). The VFD must be
displaying the trip odometer information in order for the trip odometer information to be reset.
- Message Failure - If the cluster fails to receive a distance message during normal operation, it will
flash the odometer/trip odometer distance information ON and OFF repeatedly until a distance
message is received, or until the ignition switch is turned to the OFF position, whichever occurs
first. If the cluster does not receive a distance message within one second after the ignition switch
is turned to the ON position, it will display the last distance message stored in the cluster memory.
If the cluster is unable to display distance information due to an error internal to the cluster, the
VFD display will be blank.
- Actuator Test - Each time the cluster is put through the actuator test, the VFD will display all of its
characters at once, then step through each character segment individually during the VFD portion
of the test to confirm the functionality of the VFD and the cluster control circuitry.
The PCM continually monitors the vehicle speed sensor, then sends the proper distance messages
to the instrument cluster. For further diagnosis of the odometer/trip odometer or the instrument
cluster circuitry that controls these functions, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS
AND TESTING). For proper diagnosis of the vehicle speed sensor, the PCM, the PCI data bus, or
the message inputs to the instrument cluster that control the odometer/trip odometer, a DRB III
scan tool is required. Refer to the appropriate diagnostic information.

Oil Pressure Gauge: Description and Operation
An oil pressure gauge is standard equipment on all instrument clusters. The oil pressure gauge is
located in the upper right quadrant of the instrument cluster, above the fuel gauge. The oil pressure
gauge consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry
and a fixed 90 degree scale on the cluster overlay that reads left-to-right from "L" (or Low) to "H"
(or High). An International Control and Display Symbol icon for "Engine Oil" is located on the
cluster overlay, in the center of the gauge directly above the hub of the gauge needle. The oil
pressure gauge graphics are white against a black field except for a single red graduation at the
low end of the gauge scale, making them clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned ON, the white graphics appear blue-green and the red graphics
appear red. The orange gauge needle is internally illuminated. Gauge illumination is provided by
replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic
circuit board. The oil pressure gauge is serviced as a unit with the instrument cluster.
The oil pressure gauge gives an indication to the vehicle operator of the engine oil pressure. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The oil pressure gauge is an air core
magnetic unit that receives battery current on the instrument cluster electronic circuit board through
the fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions. The cluster is programmed to move the gauge needle back to the low end of the scale
after the ignition switch is turned to the OFF position. The instrument cluster circuitry controls the
gauge needle position and provides the following features:
- Engine Oil Pressure Message - The instrument cluster circuitry restricts the oil pressure gauge
needle operation in order to provide readings that are consistent with customer expectations. Each
time the cluster receives a message from the PCM indicating the engine oil pressure is between
about 6.9 kPa (1 psi) and 137.9 kPa (20 psi), the cluster holds the gauge needle at a point about
11 degrees above the low end of normal increment on the gauge scale. Each time the cluster
receives a message from the PCM indicating the engine oil pressure is between about 517.1 kPa
(75 psi) and 755 kPa (109.5 psi), the cluster holds the gauge needle at a point about 7.4 degrees
below the high end of normal increment on the gauge scale. When the cluster receives messages
from the PCM indicating the engine oil pressure is between about 137.9 kPa (20 psi) and 517.1
kPa (75 psi), the gauge needle is moved to the actual pressure position on the gauge scale.
- Engine Oil Pressure Low Message - Each time the cluster receives a message from the PCM
indicating the engine oil pressure is below about 6.9 kPa (1 psi), the gauge needle is moved to the
L (Low) graduation at the far left end of the gauge scale, the check gauges indicator is illuminated,
and a single chime tone is generated. The gauge needle remains at the low end of the scale and
the check gauges indicator remains illuminated until the cluster receives a message from the PCM
indicating that the engine oil pressure is above about 6.9 kPa (1 psi), or until the ignition switch is
turned to the OFF position, whichever occurs first. The cluster will only turn the check gauges
indicator lamp ON in response to an engine oil pressure low message if the engine speed message
is greater than zero.
- Engine Oil Pressure High Message - Each time the cluster receives a message from the PCM
indicating the engine oil pressure is above about 755 kPa (109.5 psi), the gauge needle is moved
to the H (High) graduation at the far right end of the gauge scale. The gauge needle remains at the
high end of the scale until the cluster receives a message from the PCM indicating that the engine
oil pressure is below about 755 kPa (109.5 psi), or until the ignition switch is turned to the OFF
position, whichever occurs first.
- Message Failure - If the cluster fails to receive an engine oil pressure message, it will hold the
gauge needle at the last indication until a new message is received, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the engine oil pressure sensor to determine the engine oil pressure.
The PCM then sends the proper engine oil pressure messages to the instrument cluster. For
further diagnosis of the oil pressure gauge or the instrument cluster circuitry that controls the
gauge, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). If the instrument cluster
turns ON the check gauges indicator due to a low oil pressure gauge reading, it may indicate that
the engine or the engine oiling system requires service. For proper diagnosis of the engine oil
pressure sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster that
control the oil pressure gauge, a DRB III scan tool is required. Refer to the appropriate diagnostic
information.

The Overdrive OFF Indicator (VFD) is part of the cluster electronic circuit board, and is visible
through a cutout located in the lower right corner of the cluster overlay.

Overdrive Indicator Lamp: Description and Operation
OVERDRIVE OFF INDICATOR
An overdrive OFF indicator is standard equipment on all instrument clusters. However, on vehicles
not equipped with the optional overdrive automatic transmission, this indicator is electronically
disabled. The overdrive OFF indicator consists of the text "O/D OFF", which appears in the lower
portion of the electronic gear selector indicator Vacuum Fluorescent Display (VFD). The VFD is
part of the cluster electronic circuit board, and is visible through a cutout located in the lower right
corner of the cluster overlay. The dark lens of the VFD prevents the indicator from being clearly
visible when it is not illuminated. The text "O/D OFF" appears in an amber color and at the same
lighting level as the gear selector indicator information when it is illuminated by the instrument
cluster electronic circuit board. The overdrive OFF indicator is serviced as a unit with the VFD in
the instrument cluster.
The overdrive OFF indicator gives an indication to the vehicle operator when the OFF position of
the overdrive OFF switch has been selected, disabling the electronically controlled overdrive
feature of the automatic transmission. This indicator is controlled by the instrument cluster circuit
board based upon cluster programming and electronic messages received by the cluster from the
Powertrain Control Module (PCM) over the Programmable Communications Interface (PCI) data
bus. The overdrive OFF indicator receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the indicator will always be OFF when the ignition switch
is in any position except ON or Start. The indicator only illuminates when it is switched to ground by
the instrument cluster circuitry. The instrument cluster will turn ON the overdrive OFF indicator for
the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the overdrive OFF indicator
is illuminated for about two seconds as a bulb test.
- Overdrive OFF Lamp-ON Message - Each time the cluster receives an overdrive OFF lamp-ON
message from the PCM indicating that the OFF position of the overdrive OFF switch has been
selected, the overdrive OFF indicator will be illuminated. The indicator remains illuminated until the
cluster receives an overdrive OFF lamp-OFF message from the PCM, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the overdrive OFF indicator
will be turned ON, then OFF again during the VFD portion of the test to confirm the functionality of
the VFD, and again during the bulb check portion of the test to confirm the functionality of the
cluster control circuitry.
The PCM continually monitors the overdrive OFF switch to determine the proper outputs to the
automatic transmission. The PCM then sends the proper overdrive OFF lamp-ON and lamp-OFF
messages to the instrument cluster. For further diagnosis of the overdrive OFF indicator or the
instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT/CLUSTER DIAGNOSIS AND TESTING). For proper diagnosis of the overdrive control system, the PCM, the
PCI data bus, or the message inputs to the instrument cluster that control the overdrive OFF
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Component Information > Description and Operation
Parking Brake Warning Lamp: Description and Operation
BRAKE/PARK BRAKE INDICATOR
A brake indicator is standard equipment on all instrument clusters. The brake indicator is located in
the Information Center area of the instrument cluster; to the right of center. The brake indicator
consists of a stenciled cutout of the word "BRAKE" and the International Control and Display
Symbol icons for "Brake Failure" and "Parking Brake" in the opaque layer of the instrument cluster
overlay. The dark outer layer of the overlay prevents the indicator from being clearly visible when it
is not illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the
"BRAKE" text and the two icons to appear in red through the translucent outer layer of the overlay
when the indicator is illuminated from behind by a Light Emitting Diode (LED) soldered onto the
instrument cluster electronic circuit board. The brake indicator is serviced as a unit with the
instrument cluster.
The brake indicator gives an indication to the vehicle operator when the parking brake is applied, or
when there are certain brake hydraulic system malfunctions. This indicator is controlled by a
transistor on the instrument cluster circuit board based upon cluster programming, and electronic
messages received by the cluster from the Central Timer Module (CTM) and the Controller Antilock
Brake (CAB) over the Programmable Communications Interface (PCI) data bus. The brake
indicator Light Emitting Diode (LED) receives battery current on the instrument cluster electronic
circuit board through the fused ignition switch output (run-start) circuit whenever the ignition switch
is in the ON or Start positions; therefore, the LED will always be OFF when the ignition switch is in
any position except ON or Start. The LED only illuminates when it is provided a path to ground by
the instrument cluster transistor. The instrument cluster will turn ON the brake indicator for the
following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the brake indicator is
illuminated by the instrument cluster for about four seconds as a bulb test.
- Brake Lamp-ON Message - Each time the cluster receives a lamp-on message from the CTM or
the CAB, the brake indicator will be illuminated. If the park brake is applied or not fully released, or
if the pressures in the two halves of the split brake hydraulic system are not equal with the ignition
switch in the ON position, the brake indicator is illuminated solid. The brake indicator will blink ON
and OFF repeatedly when the park brake is applied or not fully released and the ignition switch is in
the ON position if the automatic transmission is not in Park or Neutral. The indicator remains
illuminated until the cluster receives lamp-OFF messages from both the CTM and the CAB, or until
the ignition switch is turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the instrument cluster is put through the actuator test, the brake
indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the
functionality of the LED and the cluster control circuitry.
The park brake switch on the park brake pedal mechanism provides a hard wired ground input to
the CTM circuitry through the park brake switch sense circuit whenever the park brake is applied or
not fully released. The CTM then sends the proper lamp-ON or lamp-OFF messages to the
instrument cluster. The brake pressure switch on the brake combination valve provides a hard
wired ground input to the CAB circuitry through the brake pressure switch sense circuit whenever
the pressures in the two halves of the split brake hydraulic system are unequal. The CAB then
sends the proper lamp-ON or lamp-OFF messages to the instrument cluster. If the CAB sends a
lamp-ON message after the bulb test, it indicates that the CAB has detected a brake hydraulic
system malfunction and/or that the ABS system has become inoperative. The CAB will store a
Diagnostic Trouble Code (DTC) for any malfunction it detects. The park brake switch input to the
CTM and the brake pressure switch input to the CAB can be diagnosed using conventional
diagnostic tools and methods. For proper diagnosis of the antilock brake system, the CTM, the
CAB, the PCI data bus, or the message inputs to the instrument cluster that control the brake
indicator, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Fig. 1 Central Timer Module
The Central Timer Module is located behind the left side kick panel. It contains 26-way, 16-way and
12-way connectors.
The high-line Central Timer Module (CTM) can also control some features of the audio system
when the vehicle is equipped with the optional RAZ radio receiver and remote radio switches. A
high-line CTM is used on high-line versions of this vehicle. The CTM combines the functions of a
chime/buzzer module, an intermittent wipe module, an illuminated entry module, a remote keyless
entry module, and a vehicle theft security
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Relays and Modules - Instrument Panel >
Audible Warning Device Control Module > Component Information > Diagrams > Page 7471
system module in a single unit.
The high-line CTM also controls and integrates many of the additional electronic functions and
features included on models with this option. The RAZ radio receiver with a remote radio switch
option is one of the features that the CTM controls. The CTM is programmed to send switch status
messages over the J185O data bus to control the volume, seek, and pre-set station advance
functions of the RAZ radio receiver. The CTM monitors the status of the remote radio switches
located on the steering wheel through a hard wired circuit. The CTM then sends the proper switch
status messages to the radio receiver. The electronic circuitry within the radio receiver responds to
the switch status messages it receives by adjusting the radio settings as requested.
In addition, radio receivers connected to the J1850 data bus have several audio system functions
that can be diagnosed using a DRB scan tool. Refer to the proper Diagnostic Procedures for more
information on DRB testing of the audio systems.
Two versions of the Central Timer Module (CTM) are available on this vehicle, a base version and
a high-line version. Whichever version of the CTM the vehicle is equipped with, it is concealed
behind the trim on the left cowl side inner panel below the instrument panel, where it is secured
with three screws. The CTM is enclosed in a molded plastic housing with three integral external
connector receptacles that connect it to the vehicle electrical system through one take out and
connector of the body wire harness, and two take outs and connectors of the instrument panel wire
harness. The base version of the CTM is used on base models of this vehicle. These base models
are not equipped with the optional power lock system, the Remote Keyless Entry (RKE) system,
the rear wiper system, the Vehicle Theft Security System (VTSS), or the remote radio controls. The
high-line version of the CTM is used on high-line vehicles that are equipped with one or more of
those options not found on base models.
The CTM utilizes integrated circuitry and information carried on the Programmable
Communications Interface (PCI) data bus network along with many hard wired inputs to monitor
many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal
circuitry and programming of the CTM allow it to supply the vehicle occupants with audible and
visual information, and to control and integrate many electronic functions and features of the
vehicle through both hard wired outputs and the transmission of electronic message outputs to
other electronic modules in the vehicle over the PCI data bus. The features that the CTM supports
or controls include the following: Automatic Door Lock - The high-line CTM provides an automatic door lock feature (also known as
rolling door locks). This is a programmable feature.
- Battery Protection - The CTM provides a battery saver feature that performs timed load shedding
whenever courtesy, reading, visor vanity, center console, glove box, or any exterior lamps are left
on with the ignition switch in the OFF position.
- Central Locking - The high-line CTM on vehicles equipped with the optional Vehicle Theft Security
System (VTSS) includes a central locking/ unlocking feature.
- Chimes - All versions of the CTM provide chime service and beep request service through an
integral chime tone generator.
- Door Lock Inhibit - The high-line CTM provides a power door lock inhibit feature.
- Enhanced Accident Response - The high-line CTM provides an optional enhanced accident
response feature. This is a programmable feature.
- Exterior Light Features - The CTM provides control of park lamps, fog lamps, and headlamps.
This includes support for optical horn (also known as flash-to-pass), headlamp time delay, daytime
running lamps (DRL - Canada only), and battery saver features.
- Interior Light Features - The CTM provides control of courtesy lamps, dome lamps, and the liftgate lamp. This includes support for a timed illuminated entry with fade-to-OFF, interior lighting
delay, courtesy illumination defeat, and battery saver features.
- Intermittent Wipe Control - The CTM provides control of the intermittent wipe delay, and
wipe-after-wash features for the front wiper and washer system. The high-line CTM also provides
these same features for the optional rear wiper and washer system.
- Panic Mode - The high-line CTM provides support for the optional RKE system panic mode
including horn chirp, headlamp flash, and park lamp flash features.
- Power Lock Control - The high-line CTM provides the optional power lock system features,
including support for the automatic door lock and door lock inhibit modes.
- Programmable Features - The CTM provides support for certain programmable features.
- Remote Keyless Entry - The high-line CTM provides the optional Remote Keyless Entry (RKE)
system features, including support for the RKE Lock (with optional horn chirp and park lamps
flash), Unlock (with optional park lamps flash, driver-door- only unlock, and unlock-all-doors),
Panic, and illuminated entry modes, as well as the ability to be programmed to recognize up to four
RKE transmitters. The RKE horn chirp, park lamps flash, driver- door-only unlock, and
unlock-all-doors features are programmable.
- Remote Radio Switch Interface - The high- line CTM monitors and transmits the status of the
optional remote radio switches on the steering wheel.
- Speed Sensitive Intermittent Wipe Control - The CTM provides a speed sensitive front intermittent
wipe feature.
- Vehicle Theft Security System - The high-line CTM provides control of the optional Vehicle Theft
Security System (VTSS) features, including support for the central locking/unlocking mode and
control of the Security indicator in the instrument cluster.
Hard wired circuitry connects the CTM to the electrical system of the vehicle. These hard wired
circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained
by many different methods. These circuits may be connected to each other, to the vehicle electrical
system and to the CTM through the use of a combination of soldered splices, splice block
connectors, and many different types of wire harness terminal connectors and insulators.
All versions of the CTM for this model are serviced only as a complete unit. Many of the electronic
features in the vehicle controlled or supported by the CTM are programmable using the DRB III
scan tool. In addition, the CTM software is Flash compatible, which means it can be reprogrammed
using Flash reprogramming procedures. However, if any of the CTM hardware components are
damaged or faulty, the entire CTM unit must be replaced. The hard wired inputs or outputs of all
CTM versions can be diagnosed using conventional diagnostic tools and methods; however, for
diagnosis of the CTM or the PCI data bus, the use of a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

The microprocessor-based Central Timer Module (CTM) monitors many hard wired switch and
sensor inputs as well as those resources it shares with other electronic modules in the vehicle
through its communication over the Programmable Communications Interface (PCI) data bus
network. The internal programming and all of these inputs allow the CTM microprocessor to
determine the tasks it needs to perform and their priorities, as well as both the standard and
optional features that it should provide. The CTM programming then performs those tasks and
provides those features through both PCI data bus communication with other electronic modules
and through hard wired outputs through a number of driver circuits, relays, and actuators. These
outputs allow the CTM the ability to control numerous accessory systems in the vehicle.
The CTM operates on battery current received through two fuses in the Junction Block (JB) on two
non-switched fused B(+) circuits, a fused ignition switch output (run-start) circuit, and a fused
ignition switch output (run-acc) circuit. This arrangement allows the CTM to provide some features
regardless of the ignition switch position, while other features will operate only with the ignition
switch in the Accessory, ON, and/or Start positions. The CTM receives ground through its
connector and take out of the instrument panel wire harness on three separate ground circuits. Two
of these circuits are grounded through a take out of the instrument panel wire harness with an
eyelet terminal connector that is secured by a nut to a ground stud on the left inner cowl side panel
near the CTM, while the third circuit is grounded through a take out of the instrument panel wire
harness with an eyelet terminal connector that is secured by a ground screw to the left side of the
floor panel transmission tunnel near the Airbag Control Module (ACM).
The CTM monitors its own internal circuitry as well as many of its input and output circuits, and will
store a Diagnostic Trouble Code (DTC) in electronic memory for any failure it detects. These DTCs
can be retrieved and diagnosed using a DRB III scan tool. Refer to the appropriate diagnostic
information.

Computers and Control Systems / Body Control Module. See: Body and Frame/Body Control
Systems/Central Timer Module
The hard wired inputs to and outputs from the Central Timer Module (CTM) may be diagnosed and
tested using conventional diagnostic tools and methods.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the CTM.
In order to obtain conclusive testing of the CTM, the Programmable Communications Interface
(PCI) data bus network and all of the electronic modules that provide inputs to or receive outputs
from the CTM must also be checked. The most reliable, efficient, and accurate means to diagnose
the CTM, the PCI data bus network, and the electronic modules that provide inputs to or receive
outputs from the CTM requires the use of a DRB III scan tool. Refer to the appropriate diagnostic
information. The DRB III scan tool can provide confirmation that the PCI data bus network is
functional, that all of the electronic modules are sending and receiving the proper messages over
the PCI data bus, and that the CTM is receiving the proper hard wired inputs and responding with
the proper hard wired outputs needed to perform its many functions.

Seat Belt Reminder Lamp: Description and Operation
A seatbelt indicator is standard equipment on all instrument clusters. The seatbelt indicator is
located in the Information Center area of the instrument cluster, to the right of center. The seatbelt
indicator consists of a stencilled cutout of the International Control and Display Symbol icon for
"Seat Belt" in the opaque layer of the instrument cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible when it is not illuminated. A red lens behind the
cutout in the opaque layer of the overlay causes the icon to appear in red through the translucent
outer layer of the overlay when the indicator is illuminated from behind by a Light Emitting Diode
(LED) soldered onto the instrument cluster electronic circuit board. The seatbelt indicator is
serviced as a unit with the instrument cluster.
The seatbelt indicator gives an indication to the vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor on the instrument cluster circuit board based
upon cluster programming and a hard wired input from the seatbelt switch in the driver side front
seatbelt retractor through the seat belt indicator driver circuit. The seatbelt indicator Light Emitting
Diode (LED) receives battery current on the instrument cluster electronic circuit board through the
fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions; therefore, the indicator will always be OFF when the ignition switch is in any position
except ON or Start. The LED only illuminates when it is switched to ground by the instrument
cluster transistor. The instrument cluster will turn ON the seatbelt indicator for the following
reasons:
- Seatbelt Reminder Function - Each time the cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indicator will be illuminated as a seatbelt reminder for
about seven seconds, or until the ignition switch is turned to the OFF position, whichever occurs
first. This reminder function will occur regardless of the status of the seatbelt switch input to the
cluster.
- Driver Side Front Seatbelt Not Buckled - Following the seatbelt reminder function, each time the
cluster detects an open circuit on the seat belt indicator driver circuit (seatbelt switch open - seatbelt unbuckled) with the ignition switch in the Start or ON positions, the indicator will be illuminated.
The seatbelt indicator remains illuminated until the seat belt indicator driver input to the cluster is
closed to ground (seatbelt switch closed - seatbelt buckled), or until the ignition switch is turned to
the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The seatbelt switch input to the instrument cluster circuitry can be diagnosed using conventional
diagnostic tools and methods. For further diagnosis of the seatbelt indicator or the instrument
cluster circuitry that controls the LED, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND
TESTING).

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each door. The switches close a path to
ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Fuel Gauge Sender: Description and Operation
FUEL LEVEL SENDING UNIT / SENSOR
The fuel gauge sending unit (fuel level sensor) is attached to the side of the fuel pump module. The
sending unit consists of a float, an arm, and a variable resistor track (card).
The fuel pump module has 4 different circuits (wires). Two of these circuits are used for the fuel
gauge sending unit for fuel gauge operation, and for certain OBD II emission requirements. The
other 2 wires are used for electric fuel pump operation.
For Fuel Gauge Operation: A constant input voltage source of about 12 volts (battery voltage) is
supplied to the resistor track on the fuel gauge sending unit. This is fed directly from the Powertrain
Control Module (PCM). NOTE: For diagnostic purposes, this 12V power source can only be verified
with the circuit opened (fuel pump module electrical connector unplugged). With the connectors
plugged, output voltages will vary from about 0.6 volts at FULL, to about 8.6 volts at EMPTY (about
8.6 volts at EMPTY for Jeep models, and about 7.0 volts at EMPTY for Dodge Truck models). The
resistor track is used to vary the voltage (resistance) depending on fuel tank float level. As fuel
level increases, the float and arm move up, which decreases voltage. As fuel level decreases, the
float and arm move down, which increases voltage. The varied voltage signal is returned back to
the PCM through the sensor return circuit.
Both of the electrical circuits between the fuel gauge sending unit and the PCM are hard-wired (not
multi-plexed). After the voltage signal is sent from the resistor track, and back to the PCM, the PCM
will interpret the resistance (voltage) data and send a message across the multi-plex bus circuits to
the instrument panel cluster. Here it is translated into the appropriate fuel gauge level reading.
Refer to Instrument Panel for additional information.
For OBD II Emission Monitor Requirements: The PCM will monitor the voltage output sent from the
resistor track on the sending unit to indicate fuel level. The purpose of this feature is to prevent the
OBD II system from recording/setting false misfire and fuel system monitor diagnostic trouble
codes. The feature is activated if the fuel level in the tank is less than approximately 15 percent of
its rated capacity. If equipped with a Leak Detection Pump (EVAP system monitor), this feature will
also be activated if the fuel level in the tank is more than approximately 85 percent of its rated
capacity.

Fuel Gauge Sender: Testing and Inspection
The fuel gauge sending unit contains a variable resistor (track). As the float moves up or down,
electrical resistance will change. Refer to Instrument Panel and Gauges for Fuel Gauge testing. To
test the gauge sending unit only, it must be removed from vehicle. The unit is part of the fuel pump
module. Refer to Fuel Pump Module Removal/installation for procedures. Measure the resistance
across the sending unit terminals. With float in up position, resistance should be 20 ohms ± 6%.
With float in down position, resistance should be 270 ohms ± 6%.

Speedometer Head: Description and Operation
SPEEDOMETER
A speedometer is standard equipment on all instrument clusters. The speedometer is located next
to the tachometer, just to the right of center in the instrument cluster. The speedometer consists of
a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210
degree primary scale on the gauge dial face that reads left-to-right either from 0 to 120 mph, or
from 0 to 200 kph, depending upon the market for which the vehicle is manufactured. Each version
also has a secondary inner scale on the gauge dial face that provides the equivalent opposite units
from the primary scale. Text appearing on the cluster overlay just above the hub of the
speedometer needle abbreviates the unit of measure for the primary scale in all upper case letters
(i.e.: MPH or KPH), followed by the unit of measure for the secondary scale in all lower case letters
(i.e.: mph or kph). The speedometer graphics are white (primary scale) and red (secondary scale)
against a black field, making them clearly visible within the instrument cluster in daylight. When
illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting with the
exterior lamps turned ON, the white graphics appear blue-green and the red graphics appear red.
The orange gauge needle is internally illuminated. Gauge illumination is provided by replaceable
incandescent bulb and bulb holder units located on the instrument cluster electronic circuit board.
The speedometer is serviced as a unit with the instrument cluster.
The speedometer gives an indication to the vehicle operator of the vehicle road speed. This gauge
is controlled by the instrument cluster circuit board based upon cluster programming and electronic
messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The speedometer is an air core magnetic
unit that receives battery current on the instrument cluster electronic circuit board through the fused
ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start positions.
The cluster is programmed to move the gauge needle back to the low end of the scale after the
ignition switch is turned to the OFF position. The instrument cluster circuitry controls the gauge
needle position and provides the following features:
- Message Failure - If the cluster fails to receive a speedometer message, it will hold the gauge
needle at the last indication for about four seconds, or until the ignition switch is turned to the OFF
position, whichever occurs first. If a new speedometer message is not received after about four
seconds, the gauge needle will return to the far left (low) end of the scale.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the vehicle speed sensor to determine the vehicle road speed, then
sends the proper vehicle speed messages to the instrument cluster. For further diagnosis of the
speedometer or the instrument cluster circuitry that controls the gauge, (Refer to INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the vehicle speed sensor, the
PCM, the PCI data bus, or the message inputs to the instrument cluster that control the
speedometer, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

imprinted on the cluster overlay directly above the hub of the tachometer needle identifies that each
number on the tachometer scale is to be multiplied by 1000 rpm. The tachometer graphics are

Temperature Gauge: Description and Operation
An engine coolant temperature gauge is standard equipment on all instrument clusters. The engine
coolant temperature gauge is located in the lower left quadrant of the instrument cluster, below the
voltage gauge. The engine coolant temperature gauge consists of a movable gauge needle or
pointer controlled by the instrument cluster circuitry and a fixed 90 degree scale on the cluster
overlay that reads left-to-right from "C" (or Cold) to "H" (or Hot) for all engines. An International
Control and Display Symbol icon for "Engine Coolant Temperature" is located on the cluster
overlay, in the center of the gauge directly above the hub of the gauge needle. The engine coolant
temperature gauge graphics are white against a black field except for a single red graduation at the
high end of the gauge scale, making them clearly visible within the instrument cluster in daylight.
When illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting
with the exterior lamps turned ON, the white graphics appear blue-green and the red graphics
appear red. The orange gauge needle is internally illuminated. Gauge illumination is provided by
replaceable incandescent bulb and bulb holder units located on the instrument cluster electronic
circuit board. The engine coolant temperature gauge is serviced as a unit with the instrument
cluster.
The engine coolant temperature gauge gives an indication to the vehicle operator of the engine
coolant temperature. This gauge is controlled by the instrument cluster circuit board based upon
cluster programming and electronic messages received by the cluster from the Powertrain Control
Module (PCM) over the Programmable Communications Interface (PCI) data bus. The engine
coolant temperature gauge is an air core magnetic unit that receives battery current on the
instrument cluster electronic circuit board through the fused ignition switch output (run-start) circuit
whenever the ignition switch is in the ON or Start positions. The cluster is programmed to move the
gauge needle back to the low end of the scale after the ignition switch is turned to the OFF
position. The instrument cluster circuitry controls the gauge needle position and provides the
following features:
- Engine Temperature Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is between the low end of normal [about 54 °C (130 °F)
and the high end of normal [about 129 °C (264 °F), the gauge needle is moved to the actual
temperature position on the gauge scale.
- Engine Temperature Low Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is below the low end of normal [about 54 °C (130 °F)],
the gauge needle is held at the "C" increment at the far left end of the gauge scale. The gauge
needle remains at the far left end of the scale until the cluster receives a message from the PCM
indicating that the engine temperature is above about 54 °C (130 °F), or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Engine Temperature High Message - Each time the cluster receives a message from the PCM
indicating the engine coolant temperature is above about 122 °C (251 °F), the gauge needle is
moved to the appropriate position on the gauge scale, the check gauges indicator is illuminated,
and a single chime tone is sounded. The check gauges indicator remains illuminated until the
cluster receives a message from the PCM indicating that the engine temperature is below about
119 °C (246 °F), or until the ignition switch is turned to the OFF position, whichever occurs first.
The chime tone feature will only repeat during the same ignition cycle if the check gauges indicator
is cycled OFF and then on again by the appropriate engine temperature messages from the PCM.
- Message Failure - If the cluster fails to receive an engine temperature message, it will hold the
gauge needle at the last indication until a new message is received, or until the ignition switch is
turned to the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the engine coolant temperature sensor to determine the engine
operating temperature. The PCM then sends the proper engine coolant temperature messages to
the instrument cluster. For further diagnosis of the engine coolant temperature gauge or the
instrument cluster circuitry that controls the gauge, (Refer to INSTRUMENT CLUSTER DIAGNOSIS AND TESTING). If the instrument cluster turns ON the check gauges indicator due to
a high engine temperature gauge reading, it may indicate that the engine or the engine cooling
system requires service. For proper diagnosis of the engine coolant temperature sensor, the PCM,
the PCI data bus, or the message inputs to the instrument cluster that control the engine coolant
temperature gauge, a DRB III scan tool is required. Refer to the appropriate diagnostic information.

Temperature Warning Indicator - A/T: Description and Operation
A transmission over-temperature indicator lamp is standard equipment on all instrument clusters.
The transmission over-temperature indicator is located in the Information Center area of the
instrument cluster, to the left of center. The transmission over-temperature indicator consists of a
stencilled cutout of the words "TRANS TEMP" in the opaque layer of the instrument cluster overlay.
The dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A red lens behind the cutout in the opaque layer of the overlay causes the "TRANS
TEMP" text to appear in red through the translucent outer layer of the overlay when the indicator is
illuminated from behind by a Light Emitting Diode (LED) soldered onto the instrument cluster
electronic circuit board. The transmission overtemperature indicator is serviced as a unit with the
instrument cluster.
The transmission over-temperature indicator gives an indication to the vehicle operator when the
trans- mission fluid temperature is excessive, which may lead to accelerated transmission
component wear or failure. This indicator is controlled by a transistor on the instrument cluster
circuit board based upon cluster programming and electronic messages received by the cluster
from the Powertrain Control Module (PCM) over the Programmable Communications Interface
(PCI) data bus. The transmission over-temperature indicator Light Emitting Diode (LED) receives
battery current on the instrument cluster electronic circuit board through the fused ignition switch
output (run-start) circuit whenever the ignition switch is in the ON or Start positions; therefore, the
LED will always be OFF when the ignition switch is in any position except ON or Start. The LED
only illuminates when it is provided a path to ground by the instrument cluster transistor. The
instrument cluster will turn ON the transmission over-temperature indicator for the following
reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the transmission
over-temperature indicator is illuminated for about two seconds as a bulb test.
- Trans Over-Temp Lamp-ON Message - Each time the cluster receives a trans over-temp
lamp-ON message from the PCM indicating that the transmission fluid temperature is 135 °C (275
°F) or higher, the indicator will be illuminated and a single chime tone is sounded. The lamp
remains illuminated until the cluster receives a trans over-temp lamp-OFF message from the PCM,
or until the ignition switch is turned to the OFF position, whichever occurs first. The chime tone
feature will only repeat during the same ignition cycle if the transmission over-temperature indicator
is cycled OFF and then on again by the appropriate trans over-temp messages from the PCM.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The PCM continually monitors the transmission temperature sensor to determine the transmission
operating condition, then sends the proper messages to the instrument cluster. If the instrument
cluster turns ON the transmission over-temperature indicator due to a high transmission oil
temperature condition, it may indicate that the transmission and/or the transmission cooling system
are being overloaded or that they require service. For further diagnosis of the transmission
over-temperature indicator or the instrument cluster circuitry that controls the LED, (Refer to
INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). For proper diagnosis of the transmission
temperature sensor, the PCM, the PCI data bus, or the message inputs to the instrument cluster
that control the transmission over-temperature indicator, a DRB III scan tool is required. Refer to
the appropriate diagnostic information.

GEAR SELECTOR INDICATOR
An electronic automatic transmission gear selector indicator is standard factory-installed equipment
on this model. The gear selector indicator information is displayed in a Vacuum-Fluorescent
Display (VFD), which is visible through a small window cutout located in the lower right quadrant of
the cluster overlay. The gear selector indicator displays the following characters from left to right:
'P," "R," "N," "D," "2," and "1." Respectively, these characters represent the park, reverse, neutral,
drive, second gear, and first gear positions of the transmission gear selector lever on the steering
column. The VFD illuminates a rectangular box around the character that represents the currently
selected lever position.
During daylight hours (exterior lamps OFF) the gear selector indicator VFD is illuminated at full
brightness for clear visibility. At night (exterior lamps are ON) the VFD lighting level is adjusted with
the other cluster illumination lamps using the panel lamps dimmer thumbwheel on the headlamp
switch. However, a "Parade" mode position of the panel lamps dimmer thumbwheel allows the VFD
to be illuminated at full brightness while the exterior lamps are turned ON during daylight hours.
The gear selector indicator VFD is serviced as a unit with the instrument cluster.
The electronic gear selector indicator gives an indication to the vehicle operator of the transmission
gear that has been selected with the automatic transmission gear selector lever. This gauge is
controlled by the instrument cluster circuit board based upon cluster programming. The cluster
circuitry automatically configures itself for the proper automatic transmission model based upon the
hard wired transmission range sensor mux circuit input to the cluster. Each time the cluster is
disconnected from battery current for more than about five minutes, it must configure itself again for
the automatic transmission model that is in the vehicle when it is reconnected to battery current.
The gear selector indicator information is displayed by a dedicated Vacuum Fluorescent Display
(VFD) on the instrument cluster electronic circuit board, and the VFD will not display the gear
selector indicator information after the ignition switch is turned to the OFF position. The instrument
cluster circuitry configures the gear selector indicator VFD based upon the following inputs from the
transmission range sensor:
- Open Circuit - If the transmission range sensor mux circuit is open, the cluster circuitry controls
the gear selector indicator display based upon electronic messages received from the electronic
Transmission Control Module (TCM) over the Programmable Communications Interface (PCI) data
bus. If the input is open circuit and no electronic messages are received from the TCM within two
seconds, the instrument cluster circuitry will cycle the indicated gear selector position from P to R,
to N, to D to 2 repeatedly and continuously until the condition is resolved or until the ignition switch
is turned to the OFF position, whichever occurs first.
- Resolved Circuit - If the transmission range sensor mux circuit is resolved, the cluster circuitry
controls the gear selector indicator display based upon the resistance value of the hard wired input
from the transmission range sensor. If the cluster has configured itself for the transmission range
sensor input and detects a short to ground in the transmission range sensor mux input, the cluster
will indicate all positions in the VFD; or, if this input is open circuit, the cluster will blink all positions
in the VFD. The VFD display for the short-to-ground and open circuit conditions will continue until
the condition is resolved or until the ignition switch is turned to the OFF position, whichever occurs
first.
- Actuator Test - Each time the cluster is put through the actuator test, the VFD will display all of its
characters at once, then step through each character segment individually during the VFD portion
of the test to confirm the functionality of the VFD and the cluster control circuitry.
On models with a TCM, the TCM continually monitors the transmission range sensor, then sends
the proper gear selector indicator messages to the instrument cluster. On models without a TCM,
the instrument cluster continually monitors the hard wired transmission range sensor multiplexed
input. For further diagnosis of the gear selector indicator or the instrument cluster circuitry that
controls this function, (Refer to INSTRUMENT CLUSTER - DIAGNOSIS AND TESTING). On
models without a TCM, for further diagnosis of the transmission range sensor, (Refer to
TRANSAXLE/AUTOMATIC - RE/TRANSMISSION RANGE SENSOR - DIAGNOSIS AND
TESTING) or (Refer to TRANSAXLE/AUTOMATIC - RE/TRANSMISSION RANGE SENSOR DIAGNOSIS AND TESTING). On models with a TCM, for proper diagnosis of the transmission
range sensor, the TCM, the PCI data bus, or the message inputs to the instrument cluster that
control the gear selector indicator, a DRB III scan tool is required. Refer to the appropriate
diagnostic information.

The voltage gauge is located in the upper left quadrant of the instrument cluster, above the
temperature gauge.

Dodge Workshop Manuals > Instrument Panel, Gauges and Warning Indicators > Volt Meter Gauge > Component
Information > Locations > Page 7551
Volt Meter Gauge: Description and Operation
A voltage gauge is standard equipment on all instrument clusters. The voltage gauge is located in
the upper left quadrant of the instrument cluster, above the temperature gauge. The voltage gauge
consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a
fixed 90 degree scale on the cluster overlay that reads left-to- right from "L" (or Low) to "H" (or
High). An International Control and Display Symbol icon for "Battery Charging Condition" is located
on the cluster overlay, in the center of the gauge directly above the hub of the gauge needle. The
voltage gauge graphics are white against a black field except for a single red graduation at each
end of the gauge scale, making them clearly visible within the instrument cluster in daylight. When
illuminated from behind by the panel lamps dimmer controlled cluster illumination lighting with the
exterior lamps turned ON, the white graphics appear blue-green and the red graphics appear red.
The orange gauge needle is internally illuminated. Gauge illumination is provided by replaceable
incandescent bulb and bulb holder units located on the instrument cluster electronic circuit board.
The voltage gauge is serviced as a unit with the instrument cluster.
The voltage gauge gives an indication to the vehicle operator of the electrical system voltage. This
gauge is controlled by the instrument cluster circuit board based upon cluster programming and
electronic messages received by the cluster from the Powertrain Control Module (PCM) over the
Programmable Communications Interface (PCI) data bus. The voltage gauge is an air core
magnetic unit that receives battery current on the instrument cluster electronic circuit board through
the fused ignition switch output (run-start) circuit whenever the ignition switch is in the ON or Start
positions. The cluster is programmed to move the gauge needle back to the low end of the scale
after the ignition switch is turned to the OFF position. The instrument cluster circuitry controls the
gauge needle position and provides the following features:
- Charge Fail Message - Each time the cluster receives a message from the PCM indicating a
charge fail condition (system voltage is 10.8 volts or lower), the gauge needle is moved to the "L"
graduation on the gauge scale and the check gauges indicator is illuminated. The gauge needle
remains on the "L" graduation and the check gauges indicator remains illuminated until the cluster
receives a message from the PCM indicating there is no charge fail condition (system voltage is
10.9 volts or higher, but lower than 16.7 volts), or until the ignition switch is turned to the OFF
position, whichever occurs first.
- Voltage High Message - Each time the cluster receives a message from the PCM indicating a
voltage high condition (system voltage is 16.7 volts or higher), the gauge needle is moved to the
"H" graduation on the gauge scale and the check gauges indicator is illuminated. The gauge
needle remains on the "H" graduation and the check gauges indicator remains illuminated until the
cluster receives a message from the PCM indicating there is no voltage high condition (system
voltage is 16.6 volts or lower, but higher than 10.9 volts), or until the ignition switch is turned to the
OFF position, whichever occurs first.
- Message Failure - If the cluster fails to receive a system voltage message, it will hold the gauge
needle at the last indication until a new message is received, or until the ignition switch is turned to
the OFF position, whichever occurs first.
- Actuator Test - Each time the cluster is put through the actuator test, the gauge needle will be
swept to several calibration points on the gauge scale in a prescribed sequence in order to confirm
the functionality of the gauge and the cluster control circuitry.
The PCM continually monitors the system voltage to control the generator output. The PCM then
sends the proper system voltage messages to the instrument cluster. For further diagnosis of the
voltage gauge or the instrument cluster circuitry that controls the gauge, (Refer to INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING). If the instrument cluster turns ON the check gauges
indicator due to a charge fail or voltage high condition, it may indicate that the charging system
requires service. For proper diagnosis of the charging system, the PCI data bus, or the message
inputs to the instrument cluster that control the voltage gauge, a DRB III scan tool is required. Refer
to the appropriate diagnostic information.

Brake Light Switch: Description and Operation
The plunger type brake lamp switch is mounted on a bracket attached to the brake pedal support.
CAUTION: The switch can only be adjusted during initial installation. If the switch is not adjusted
properly a new switch must be installed.
The primary function of the switch is to turn ON the brake lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses
the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes
applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to
anticipate the need for an RWAL stop.

How to Use Wiring Diagrams
DaimlerChrysler Corporation wiring diagrams are designed to provide information regarding the
vehicles wiring content. In order to effectively use the wiring diagrams to diagnose and repair
DaimlerChrysler Corporation vehicles, it is important to understand all of their features and
characteristics.
General Information (Part 1 of 2)
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the
page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).

Dodge Workshop Manuals > Lighting and Horns > Door Switch > Component Information > Diagrams > Diagram
Information and Instructions > Page 7610
General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))

as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Door Switch: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each door. The switches close a path to
ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Hazard Warning Flasher: Description and Operation
Fig. 4 Combination Flasher
COMBINATION FLASHER
The combination flasher is located in a dedicated connector on a take out of the instrument panel
wire harness, located under the instrument panel just outboard of the instrument panel steering
column opening. The combination flasher is a smart relay that functions as both the turn signal
system and the hazard warning system flasher. The combination flasher has fourteen blade-type
terminals that connect it to the vehicle electrical system through fourteen matching cavities in the
instrument panel wire harness connector; however, only ten of the combination flasher terminals
are used in this application. The combination flasher contains active electronic Integrated Circuitry
(IC) elements. This flasher is designed to handle the current flow requirements of the
factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as
when towing a trailer with lights, the combination flasher will automatically try to compensate to
keep the flash rate the same.
The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be
replaced.
The combination flasher has fourteen blade-type terminals, but only ten are used in this application.
These ten terminals are intended for the following inputs and outputs: fused B(+), fused ignition
switch output, right turn signal sense, left turn signal sense, hazard flasher signal, brake lamp
switch output, and two outputs each for the right and left turn signal circuits. Constant battery
voltage is supplied to the flasher so that it can perform the hazard warning function, and ignition
switched battery voltage is supplied for the turn signal function. The Integrated Circuit (IC) within
the combination flasher contains the logic that controls the flasher operation and the flash rate. The
IC receives separate sense ground inputs from the multi-function switch for the hazard flasher, right
turn signal, and left turn signal. A special design feature of the combination flasher allows it to
"sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the
condition by flashing the remaining bulbs in the affected circuit at a higher rate (120
flashes-per-minute or higher). Conventional flashers either continue flashing at their typical rate
(heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type).
Because of the active electronic elements within the combination flasher, it cannot be tested with
conventional automotive electrical test equipment. If the combination flasher is believed to be faulty,
test the turn signal and hazard warning system. Then replace the combination flasher with a known
good unit to confirm system operation. (Refer to TURN SIGNAL & HAZARD WARNING SYSTEM DIAGNOSIS AND TESTING).

Hazard Warning Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Lighting and Horns > Hazard Warning Lamps > Hazard Warning Switch > Component
Information > Diagrams > Page 7653
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Hi-Beam Indicator Lamp: Description and Operation
A high beam indicator is standard equipment on all instrument clusters. The high beam indicator is
located near the upper edge of the instrument cluster overlay, between the tachometer and the
speedometer. The high beam indicator consists of a stenciled cutout of the International Control
and Display Symbol icon for "High Beam" in the opaque layer of the instrument cluster overlay. The
dark outer layer of the overlay prevents the indicator from being clearly visible when it is not
illuminated. A blue lens behind the cutout in the opaque layer of the overlay causes the icon to
appear in blue when it is illuminated from behind by a replaceable incandescent bulb and bulb
holder unit located on the instrument cluster electronic circuit board. The high beam indicator is
serviced as a unit with the instrument cluster.
The high beam indicator gives an indication to the vehicle operator when the headlamp high beams
are illuminated. This indicator is hard wired on the instrument cluster electronic circuit board, and is
controlled by the Central Timer Module (CTM) through the high beam indicator driver circuit input to
the cluster based upon a control signal to the CTM from the headlamp beam select switch. The
headlamp beam select switch is integral to the multi-function switch on the left side of the steering
column. The high beam indicator bulb receives battery current on the instrument cluster electronic
circuit board through a fused B(+) circuit at all times; therefore, the indicator remains operational
regardless of the ignition switch position. The indicator only illuminates when it is provided with a
path to ground by the CTM. The high beam indicator can be diagnosed using conventional
diagnostic tools and methods. For proper diagnosis of the CTM and the inputs to the CTM that
control the high beam indicator driver circuit, a DRB III scan tool is required. Refer to the
appropriate diagnostic information.

Dodge Workshop Manuals > Lighting and Horns > Horn > Horn Relay > Component Information > Locations > Page 7676
Horn Relay: Description and Operation
The horn relay is a electromechanical device that switches battery current to the horn when the
horn switch grounds the relay coil. The horn relay is located in the Junction Block (JB), on the left
end of the instrument panel in the passenger compartment. If a problem is encountered with a
continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the
JB until further diagnosis is completed. See the fuse and relay layout label affixed to the inside
surface of the fuse access panel for horn relay identification and location.
The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to
the ISO specifications have common physical dimensions, current capacities, terminal patterns,
and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO
relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity
is lower, and the physical dimensions are smaller than those of the conventional ISO relay.
The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it
draws the movable contact away from the normally closed fixed contact, and holds it against the
other (normally open) fixed contact.
When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the
normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil
in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized.

and should be hot at all times. If OK, go to Step 2. If not OK, repair
the open circuit to the fuse in the PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the
energized position. This terminal supplies battery
voltage to the horn(s). There should be continuity between the cavity for relay terminal 87 and the
horn relay output circuit cavity of each horn wire harness connector at all times. If OK, go to Step 4.
If not OK, repair the open circuit to the horn(s) as required.
4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is connected to
battery voltage and should be hot at all times. Check
for battery voltage at the cavity for relay terminal 86. If OK, go to Step 5. If not OK, repair the open
circuit to the fuse in the PDC as required.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded
through the horn switch when the horn switch is
depressed. On vehicles equipped with the Remote Keyless Entry (RKE) system, the horn relay coil
ground terminal can also be grounded by the Central Timer Module (CTM) in response to certain
inputs related to the RKE system or the Vehicle Theft Security System. Check for continuity to
ground at the cavity for relay terminal 85. There should be continuity with the horn switch
depressed, and no continuity with the horn switch released. If not OK, (Refer to HORN SWITCH DIAGNOSIS AND TESTING).

Horn Switch: Description and Operation
Fig. 3 Driver Side Airbag Module Trim Cover And Horn Switch
A center-blow, normally open, resistive membrane-type horn switch is secured with heat stakes to
the back side of the driver side airbag module trim cover in the center of the steering wheel . The
switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two
membranes are secured to each other around the perimeter. Inside the switch, the centers of the
facing surfaces of these membranes each has a grid made with an electrically conductive material
applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all
times. The grid of the other membrane is connected to the horn relay control circuit.
The steering wheel and steering column must be properly grounded in order for the horn switch to
function properly. The horn switch is only serviced as a part of the driver side airbag module trim
cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side
airbag module trim cover and horn switch must be replaced as a unit.
When the center area of the driver side airbag trim cover is depressed, the electrically conductive
grids on the facing surfaces of the horn switch membranes contact each other, closing the switch
circuit. The completed horn switch circuit provides a ground for the control coil side of the horn
relay, which activates the relay. When the horn switch is released, the resistive tension of the
convex membrane separates the two electrically conductive grids and opens the switch circuit.

Horn Relay: Description and Operation
The horn relay is a electromechanical device that switches battery current to the horn when the
horn switch grounds the relay coil. The horn relay is located in the Junction Block (JB), on the left
end of the instrument panel in the passenger compartment. If a problem is encountered with a
continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the
JB until further diagnosis is completed. See the fuse and relay layout label affixed to the inside
surface of the fuse access panel for horn relay identification and location.
The horn relay is a International Standards Organization (ISO) micro-relay. Relays conforming to
the ISO specifications have common physical dimensions, current capacities, terminal patterns,
and terminal functions. The ISO micro-relay terminal functions are the same as a conventional ISO
relay. However, the ISO micro-relay terminal pattern (or footprint) is different, the current capacity
is lower, and the physical dimensions are smaller than those of the conventional ISO relay.
The horn relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced.
The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one
movable) electrical contacts. The movable (common feed) relay contact is held against one of the
fixed contacts (normally closed) by spring pressure. When the electromagnetic coil is energized, it
draws the movable contact away from the normally closed fixed contact, and holds it against the
other (normally open) fixed contact.
When the electromagnetic coil is de-energized, spring pressure returns the movable contact to the
normally closed position. The resistor or diode is connected in parallel with the electromagnetic coil
in the relay, and helps to dissipate voltage spikes that are produced when the coil is de-energized.

1. Remove the horn relay from the JB. (Refer to HORN RELAY - REMOVAL) for the procedures. 2.
A relay in the de-energized position should have continuity between terminals 87A and 30, and no
continuity between terminals 87 and 30. If OK,
go to Step 3. If not OK, replace the faulty relay.
3. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to
Step 4. If not OK, replace the faulty relay. 4. Connect a battery to terminals 85 and 86. There
should now be continuity between terminals 30 and 87, and no continuity between terminals 87A
and 30. If OK, perform the Relay Circuit Test that follows. If not OK, replace the faulty relay.
Relay Circuit Test 1. The relay common feed terminal cavity (30) is connected to battery voltage
and should be hot at all times. If OK, go to Step 2. If not OK, repair
the open circuit to the fuse in the PDC as required.
2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized
position, but is not used for this application. Go to Step
3.
3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the
energized position. This terminal supplies battery
voltage to the horn(s). There should be continuity between the cavity for relay terminal 87 and the
horn relay output circuit cavity of each horn wire harness connector at all times. If OK, go to Step 4.
If not OK, repair the open circuit to the horn(s) as required.
4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is connected to
battery voltage and should be hot at all times. Check
for battery voltage at the cavity for relay terminal 86. If OK, go to Step 5. If not OK, repair the open
circuit to the fuse in the PDC as required.
5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded
through the horn switch when the horn switch is
depressed. On vehicles equipped with the Remote Keyless Entry (RKE) system, the horn relay coil
ground terminal can also be grounded by the Central Timer Module (CTM) in response to certain
inputs related to the RKE system or the Vehicle Theft Security System. Check for continuity to
ground at the cavity for relay terminal 85. There should be continuity with the horn switch
depressed, and no continuity with the horn switch released. If not OK, (Refer to HORN SWITCH DIAGNOSIS AND TESTING).

Brake Light Switch: Description and Operation
The plunger type brake lamp switch is mounted on a bracket attached to the brake pedal support.
CAUTION: The switch can only be adjusted during initial installation. If the switch is not adjusted
properly a new switch must be installed.
The primary function of the switch is to turn ON the brake lamps during braking. The switch is also
used to send signals to components that must know when the brakes are applied, such as the
Powertrain Control Module (PCM), which uses the signal to cancel speed control. The CAB uses
the brake switch signal to monitor brake pedal application. When the switch contacts open (brakes
applied), the CAB receives the brake applied signal. The CAB then monitors the RWAL system to
anticipate the need for an RWAL stop.

General Information (Part 2 of 2)
All switches, components, and modules are shown in the at rest position with the doors closed and
the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is
complete. A dashed line around the component indicates that the component is being shown is not
complete. Incomplete components have a reference number to indicate the page where the
component is shown complete.
It is important to realize that no attempt is made on the diagrams to represent components and
wiring as they appear on the vehicle. For example, a short
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Door Switch > Component
Information > Diagrams > Diagram Information and Instructions > Page 7751
piece of wire is treated the same as a long one. In addition, switches and other components are
shown as simply as possible, with regard to function only.
Circuit Functions
Circuit Identification Code Chart
All circuits in the diagrams use an alpha/numeric code to identify the wire and its function. To
identify which circuit code applies to a system, refer to the Circuit Identification Code Chart. This
chart shows the main circuits only and does not show the secondary codes that may apply to some
models.

- Jumper harness connectors are C400 series numbers.
- Grounds and ground connectors are identified with a "G" and follow the same series numbering
as the in-line connectors.
- Splices are identified with an "S" and follow the same series numbering as the in-line connectors.
- Component connectors are identified by the component name instead of a number. Multiple
connectors on a component use a C1, C2, etc. identifier.
Electrostatic Discharge (ESD) Sensitive Devices
Electrostatic Discharge Symbol
All ESD sensitive components are solid state and a symbol is used to indicate this. When handling
any component with this symbol comply with the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume that it is.
1. Always touch a known good ground before handling the part. This should be repeated while
handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.
2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.
3. When using a voltmeter, be sure to connect the ground lead first. 4. Do not remove the part from
its protective packing until it is time to install the part. 5. Before removing the part from its package,
ground the package to a known good ground on the vehicle.
Notes, Cautions and Warnings
Additional important information is presented in three ways: Notes, Cautions, and Warnings.
NOTES are used to help describe how switches or components operate to complete a particular
circuit. They are also used to indicate different conditions that may appear on the vehicle. For
example, an up-to and after condition.
CAUTIONS are used to indicate information that could prevent making an error that may damage
the vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a vehicle is being serviced.

Section Identification and Information
Section Identification
The wiring diagrams are grouped into individual sections. If a component is most likely found in a
particular group, it will be shown complete (all wires, connectors, and pins) within that group. For
example, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there
complete. It can, however, be shown partially in another group if it contains some associated
wiring.

Door Switch: Diagnostic Aids
Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a problem. Before condemning a component or
wiring assembly, check the following items. Connectors are fully seated
- Spread terminals, or terminal push out
- Terminals in the wiring assembly are fully seated into the connector/component and locked into
position
- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent
problem
- Damaged connector/component casing exposing the item to dirt or moisture
- Wire insulation that has rubbed through causing a short to ground
- Some or all of the wiring strands broken inside of the insulation
- Wiring broken inside of the insulation

Troubleshooting Tools
When diagnosing a problem in an electrical circuit there are several common tools necessary.
These tools are listed and explained below.
Jumper Wire
This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a
circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR,
CONNECTED BETWEEN A BATTERY FEED AND GROUND.
Voltmeter
Used to check for voltage on a circuit. Always connect the black lead to a known good ground and
the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking voltages in these circuits, use a meter with a 10 mega-ohm or greater impedance rating.
Ohmmeter
Used to check the resistance between two points of a circuit. Low or no resistance in a circuit
means good continuity.
CAUTION: Most of the electrical components used in today's vehicles are Solid State. When
checking resistance in these circuits use a meter with a 10 mega-ohm or greater impedance rating.
In addition, make sure the power is disconnected from the circuit. Circuits that are powered up by
the vehicle's electrical system can cause damage to the equipment and provide false readings.

Probing Tools
These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from
Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the
tool to insert the meter probe.
Troubleshooting Wiring Problems
When troubleshooting wiring problems, there are six steps which can aid in the procedure. The
steps are listed and explained below. Always check for nonfactory items added to the vehicle
before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify
these add-on items are not the cause of the problem.
1. Verify the problem. 2. Verify any related symptoms. Do this by performing operational checks on
components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms.
Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is
occurring, and where the
diagnosis will continue.
4. Isolate the problem area. 5. Repair the problem. 6. Verify proper operation. For this step, check
for proper operation of all items on the repaired circuit.

Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each door. The switches close a path to
ground for the Central Timer Module (CTM) when a door is opened, and open the ground path
when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit must be
replaced.
The door ajar switches close a path to ground for the Central Timer Module (CTM) when a door is
opened, and opens the ground path when a door is closed. The passenger side front door and both
rear door ajar switches are connected in a parallel-series circuit between ground and the CTM,
while the driver side front door ajar switch is connected in series between ground and the CTM to
provide a unique input. The CTM reads the switch status through an internal pull-up, then sends
the proper switch status messages to other electronic modules over the Programmable
Communications Interface (PCI) data bus network. The door ajar switches can be diagnosed using
conventional diagnostic tools and methods.

Hazard Warning Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Hazard Warning Switch >
Component Information > Diagrams > Page 7783
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Headlamp Switch: Description and Operation
The headlamp switch is located in the instrument panel, outboard of the steering column. It closes
a path to ground for the Central Timer Module (CTM) when the park or head lamps are ON and the
driver door ajar switch is closed (driver door is open). The headlamp switch opens the ground path
when the headlamp switch is turned OFF. The ground path is also opened when the driver door
ajar switch is open (driver door is closed). This switch also contains a rheostat for controlling the
illumination level of the instrument cluster lamps.
The headlamp switch cannot be repaired and, if faulty or damaged, it must be replaced.
The headlamp switch has an OFF position, a parking lamp position, and a headlamp ON position.
High beams are controlled by the multifunction switch on the steering column. The headlamp
switch cannot be repaired. It must be replaced.

Horn Switch: Description and Operation
Fig. 3 Driver Side Airbag Module Trim Cover And Horn Switch
A center-blow, normally open, resistive membrane-type horn switch is secured with heat stakes to
the back side of the driver side airbag module trim cover in the center of the steering wheel . The
switch consists of two plastic membranes, one that is flat and one that is slightly convex. These two
membranes are secured to each other around the perimeter. Inside the switch, the centers of the
facing surfaces of these membranes each has a grid made with an electrically conductive material
applied to it. One of the grids is connected to a circuit that provides it with continuity to ground at all
times. The grid of the other membrane is connected to the horn relay control circuit.
The steering wheel and steering column must be properly grounded in order for the horn switch to
function properly. The horn switch is only serviced as a part of the driver side airbag module trim
cover. If the horn switch is damaged or faulty, or if the driver side airbag is deployed, the driver side
airbag module trim cover and horn switch must be replaced as a unit.
When the center area of the driver side airbag trim cover is depressed, the electrically conductive
grids on the facing surfaces of the horn switch membranes contact each other, closing the switch
circuit. The completed horn switch circuit provides a ground for the control coil side of the horn
relay, which activates the relay. When the horn switch is released, the resistive tension of the
convex membrane separates the two electrically conductive grids and opens the switch circuit.

Turn Signal Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Lighting and Horns > Sensors and Switches - Lighting and Horns > Turn Signal Switch >
Component Information > Diagrams > Page 7802
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Turn Signal Flasher: Description and Operation
Fig. 4 Combination Flasher
COMBINATION FLASHER
The combination flasher is located in a dedicated connector on a take out of the instrument panel
wire harness, located under the instrument panel just outboard of the instrument panel steering
column opening. The combination flasher is a smart relay that functions as both the turn signal
system and the hazard warning system flasher. The combination flasher has fourteen blade-type
terminals that connect it to the vehicle electrical system through fourteen matching cavities in the
instrument panel wire harness connector; however, only ten of the combination flasher terminals
are used in this application. The combination flasher contains active electronic Integrated Circuitry
(IC) elements. This flasher is designed to handle the current flow requirements of the
factory-installed lighting. If supplemental lighting is added to the turn signal lamp circuits, such as
when towing a trailer with lights, the combination flasher will automatically try to compensate to
keep the flash rate the same.
The combination flasher cannot be repaired or adjusted and, if faulty or damaged, it must be
replaced.
The combination flasher has fourteen blade-type terminals, but only ten are used in this application.
These ten terminals are intended for the following inputs and outputs: fused B(+), fused ignition
switch output, right turn signal sense, left turn signal sense, hazard flasher signal, brake lamp
switch output, and two outputs each for the right and left turn signal circuits. Constant battery
voltage is supplied to the flasher so that it can perform the hazard warning function, and ignition
switched battery voltage is supplied for the turn signal function. The Integrated Circuit (IC) within
the combination flasher contains the logic that controls the flasher operation and the flash rate. The
IC receives separate sense ground inputs from the multi-function switch for the hazard flasher, right
turn signal, and left turn signal. A special design feature of the combination flasher allows it to
"sense" that a turn signal circuit or bulb is not operating, and provide the driver an indication of the
condition by flashing the remaining bulbs in the affected circuit at a higher rate (120
flashes-per-minute or higher). Conventional flashers either continue flashing at their typical rate
(heavy-duty type), or discontinue flashing the affected circuit entirely (standard-duty type).
Because of the active electronic elements within the combination flasher, it cannot be tested with
conventional automotive electrical test equipment. If the combination flasher is believed to be faulty,
test the turn signal and hazard warning system. Then replace the combination flasher with a known
good unit to confirm system operation. (Refer to TURN SIGNAL & HAZARD WARNING SYSTEM DIAGNOSIS AND TESTING).

Turn Signal Indicator: Description and Operation
Two turn signal indicators, one right and one left, are standard equipment on all instrument
clusters. The turn signal indicators are located near the upper edge of the instrument cluster
overlay, between the speedometer and the tachometer. Each turn signal indicator consists of a
stenciled cutout of the International Control and Display Symbol icon for "Turn Warning" in the
opaque layer of the instrument cluster overlay. The dark outer layer of the overlay prevents these
icons from being clearly visible when their lamps are not illuminated. The icons appear in green
through the translucent outer layer of the overlay when the indicator is illuminated from behind by a
replaceable incandescent bulb and bulb holder unit located on the instrument cluster electronic
circuit board. The turn signal indicators are serviced as a unit with the instrument cluster.
The turn signal indicators give an indication to the vehicle operator that the turn signal (left or right
indicator flashing) or hazard warning (both left and right indicators flashing) have been selected.
These indicators are controlled by two individual hard wired inputs to the instrument cluster
electronic circuit board. The turn signal indicator bulbs are grounded on the instrument cluster
electronic circuit board at all times. The turn signal indicator bulbs only illuminate when they are
provided with battery current by the turn signal and hazard warning circuitry of the combination
flasher through separate left and right turn signal circuit inputs to the instrument cluster; therefore,
these indicators can be illuminated, regardless of the ignition switch position.
The turn signal indicators are connected in series between ground and the output of the
combination flasher circuitry, but in parallel with the other turn signal circuits. This arrangement
allows the turn signal indicators to remain functional regardless of the condition of the other circuits
in the turn signal and hazard warning system. For more information on the turn signal and hazard
warning system, (Refer to LIGHTING - TURN SIGNAL & HAZARD WARNING SYSTEM). The turn
signal indicators can be diagnosed using conventional diagnostic tools and methods.

Turn Signal Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative turn signal indicator condition. If the problem
being diagnosed is related to inoperative turn signals or hazard warning lamps, be certain to repair
the turn signal and hazard warning system before attempting to diagnose or repair the turn signal
indicators. If no turn signal or hazard warning system problems are found, the following procedure
will help locate a short or open in the left or right turn signal indicator circuits.
1. Disconnect and isolate the battery negative cable. Remove the instrument cluster. 2. Connect
the battery negative cable. Activate the hazard warning system by moving the hazard warning
switch button to the ON position. Check for
battery voltage at the inoperative (right or left) turn signal circuit cavity of the instrument panel wire
harness connector (Connector C2) for the instrument cluster. There should be a switching (on and
OFF) battery voltage signal. If OK, replace the faulty turn signal indicator bulb. If not OK, repair the
open (right or left) turn signal circuit between the instrument cluster and the combination flasher as
required.

Turn Signal Switch: Description and Operation
Fig.14 Multi-Function Switch
MULTI-FUNCTION SWITCH
The multi-function switch is secured with two screws to the multi-function switch mounting housing
on the left side of the steering column, just below the steering wheel. The only visible parts of the
multi-function switch are the control stalk that extends through a dedicated opening in the left side
of the upper steering column shrouds, and the hazard warning switch push button that protrudes
through an opening in the upper steering column shroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and its electrical connections are all concealed
beneath the steering column shrouds. The multi-function switch control stalk has both
nomenclature and International Control and Display Symbol graphics applied to it, which identify its
many functions. An International Control and Display Symbol icon for "Hazard Warning" is applied
to the top of the hazard warning switch push button.
The switch housing and its controls are constructed of molded black plastic. A single connector
receptacle connects the switch to the vehicle electrical system through a take out and connector of
the instrument panel wire harness.
The multi-function switch supports the following functions and features: -
Continuous Wipe Modes - The control knob of the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
- Hazard Warning Control - The internal circuitry and hardware of the multi-function switch provide
detent switching for activation and deactivation of the hazard warning system.
- Headlamp Beam Selection - The internal circuitry and hardware of the multi-function switch
provide detent switching for selection of the headlamp high or low beams.
- Headlamp Optical Horn - The internal circuitry and hardware of the multi-function switch includes
momentary switching of the headlamp high beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows the vehicle operator to momentarily flash the
headlamp high beams as an optical signalling device.
- Intermittent Wipe Mode - The control knob of the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
- Turn Signal Control - The internal circuitry and hardware of the multi-function switch provide both
momentary non-detent switching and detent switching with automatic cancellation for both the left
and right turn signals.
- Washer Mode - The control knob of the multi- function switch provides washer system operation
when the knob is depressed towards the steering column.
The multi-function switch cannot be adjusted or repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must be replaced.
The multi-function switch uses conventionally switched outputs and a variable resistor to control the
many functions and features it provides using hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet terminal connector of the instrument panel wire
harness that is secured by a nut to a ground stud located on the left cowl side inner panel, near the
left instrument panel end bracket. When the ignition switch is in the Accessory or ON positions,
battery current from a fuse in the Junction Block (JB) is provided through a fused ignition switch
output (run acc) circuit. Following are descriptions of how the multi-function switch operates to
control the many functions and features it provides: Continuous Wipe Modes - When the control knob of the multi-function switch is rotated to the High
or Low positions, the circuitry within the
Dodge Durango 2wd Workshop Manual (V8-4.7L VIN N (2001))
Dodge Workshop Manuals > Lighting and Horns > Turn Signals > Turn Signal Switch > Component Information > Diagrams
> Page 7840
switch provides a battery current output directly to the high or low speed brush of the wiper motor.
When the control knob is in the OFF position, the circuitry within the switch connects the output of
the wiper motor park switch to the low speed brush of the wiper motor.
- Hazard Warning Control - The hazard warning push button is pushed down to unlatch the switch
and activate the hazard warning system, and pushed down again to latch the switch and turn the
system OFF. When the hazard warning switch is latched (hazard warning OFF), the push button
will be in a lowered position on the top of the steering column shroud; and, when the hazard
warning switch is unlatched (hazard warning ON), the push button will be in a raised position. The
multi-function switch hazard warning circuitry provides a signal to the hazard warning sense of the
combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
- Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering
wheel past a detent, then released to actuate the headlamp beam selection switch. Each time the
control stalk is actuated in this manner, the opposite headlamp mode from what is currently
selected will be activated. The internal circuitry of the headlamp beam selection switch directs a
ground signal output from the headlamp switch to the appropriate low beam or high beam sense of
the Central Timer Module (CTM). The CTM then controls a hard wired output to activate the
selected headlamp beams.
- Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering
wheel to just before a detent, to momentarily activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground path to the CTM high beam sense.
- Intermittent Wipe Mode - When the multi-function switch control knob is rotated to the Delay
position, the circuitry within the switch provides a battery current signal to the Central Timer Module
(CTM). If the Delay mode is selected, the control knob can then be rotated to multiple minor detent
positions, which actuates a variable resistor within the switch and provides a hard wired output to
the CTM that signals the desired delay interval for the intermittent wiper feature.
- Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When
the control stalk is moved in the upward direction, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry provides a signal to the right or left turn signal sense
of the combination flasher to activate or deactivate the flasher output to the proper turn signal
lamps. The turn signal switch has a detent position in each direction that provides turn signals with
automatic cancellation, and an intermediate, momentary position in each direction that provides
turn signals only until the multi-function switch control stalk is released. When the control stalk is
moved to a turn signal switch detent position, the cancel actuator extends toward the center of the
steering column. A turn signal cancel cam that is integral to the clock-spring mechanism rotates
with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn signal cancel actuator. The cancel actuator
latches against the cancel cam rotation in the direction opposite that which is signaled. In other
words, if the left turn signal detent is selected, the lobes of the cancel cam will ratchet past the
cancel actuator when the steering wheel is rotated to the left, but will unlatch the cancel actuator as
the steering wheel rotates to the right and returns to center, which will cancel the turn signal event
and release the control stalk from the detent so it returns to the neutral OFF position.
- Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk
towards the steering column provides a battery current output through the momentary single pole,
single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM then
provides a battery current output to operate the washer pump/motor. If the wipers are not operating
when the washer switch is actuated, the CTM will operate the wiper motor for as long as the
washer switch is depressed plus about three additional wipe cycles. If the wipers are operating in
the intermittent mode when the washer switch is actuated, the CTM will operate the wiper motor at
a fixed low speed for as long as the washer switch is depressed plus about three additional wipe
cycles before the wipers return to the selected intermittent wipe interval.

Rear Window Defogger Switch: Description and Operation
The rear window defogger switch is integral to the heater-A/C control assembly, which includes the
rear wiper and washer switches.
The rear window switch also contains the rear window defogger logic and timer circuitry, an amber
defogger indicator lamp, the rear window defogger relay, and two switch illumination lamps. The
indicator and illumination lamps in the switch pod use incandescent bulbs, which can be serviced.
The momentary-type rear window defogger switch provides a hard wired ground signal to the rear
window defogger logic and timer circuitry, each time it is depressed.
The rear window defogger timer and logic circuitry responds by energizing or de-energizing the
rear window defogger relay and the amber defogger indicator lamp, which lights to indicate when
the defogger system is turned ON. Energizing the rear window defogger relay provides electrical
current to the rear window defogger grid.
The rear window switch cannot be repaired. If any function of the switch except lighting is faulty or
damaged, the entire heater-A/C control assembly must be replaced.

Power Window Switch: Description and Operation
The power windows are controlled by two-way switches integral to the power window and lock
switch and bezel unit on the trim panel of each front door. A second power window switch in the
driver side switch and bezel unit allows the driver to control the passenger windows.
The power window switch for the driver side front door window has an Auto label on it. This switch
has a second detent position beyond the normal Down position that provides an automatic
one-touch window down feature. This feature is controlled by an electronic circuit and a relay that
are integral to the Driver Door Module.
The power window switches control the battery and ground feeds to the power window motors. All
of the passenger door power window switches receive their battery and ground feeds through the
circuitry of the Driver Door Module. When the power window lockout switch is in the Lock position,
the battery feed for the individual passenger door power window switches is interrupted.
A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition
switch is in the ON position. However, the LEDs for the passenger power window switches are
extinguished whenever the driver selects the Lock position with the power window lockout switch.

Power Window Switch: Testing and Inspection
The Light-Emitting Diode (LED) illumination lamps for all of the power window and lock switch and
bezel unit switch paddles receive battery current through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in both the power window and lock switch units and
the power windows are inoperative, (Refer to POWER WINDOWS - DIAGNOSIS AND TESTING).
If the power windows operate, but any or all of the LEDs are inoperative, the power window and
lock switch units with the inoperative LED(s) is faulty and must be replaced.
1. Check the circuit breaker in the junction block. If OK, go to Step 2. If not OK, replace the faulty
circuit breaker. 2. Turn the ignition switch to the ON position. Check for battery voltage at the circuit
breaker in the junction block. If OK, turn the ignition switch to
the OFF position and go to Step 3. If not OK, repair the circuit to the ignition switch as required.
3. Disconnect and isolate the battery negative cable. Remove the power window switch unit from
the door trim panel (passenger doors). The drivers
door switch is included with the Driver Door Module (Refer to POWER LOCKS/DOOR MODULE DIAGNOSIS AND TESTING) for service procedures. Unplug the wire harness connector from the
switch unit,

Description and Operation
Power Window Circuit Breaker: Description and Operation
An automatic resetting circuit breaker in the junction block is used to protect the power seat system
circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition
caused by an obstructed or stuck seat adjuster.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.

Description and Operation > Page 7885
Power Window Circuit Breaker: Testing and Inspection
1. Locate the circuit breaker in the junction block. Pull out the circuit breaker slightly, but be certain
that the circuit breaker terminals still contact the
terminals in the junction block cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground. 3. With the voltmeter
positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither
terminal has battery voltage, repair the open circuit from the Power Distribution Center (PDC) as
required. If the circuit breaker checks OK, but no power windows operate, refer to ALL WINDOWS
INOPERATIVE.

Power Window Motor: Description and Operation
WINDOW MOTOR
A permanent magnet reversible motor moves the window regulator through an integral gearbox
mechanism. A positive and negative battery connection to the two motor terminals will cause the
motor to rotate in one direction. Reversing the current through these same two connections will
cause the motor to rotate in the opposite direction.
In addition, each power window motor is equipped with an integral self-resetting circuit breaker to
protect the motor from overloads. The power window motor and gearbox assembly cannot be
repaired and, if faulty or damaged, the entire power window regulator assembly must be replaced.

Power Window Motor: Testing and Inspection
1. Disconnect and isolate the battery negative cable. Remove the trim panel from the door with the
inoperative power window. 2. Unplug the power window motor wire harness connector. Apply 12
volts across the motor terminals to check its operation in one direction.
Reverse the connections across the motor terminals to check the operation in the other direction.
Remember, if the window is in the full up or full down position, the motor will not operate in that
direction by design. If OK, repair the circuits from the power window motor to the power window
switch as required. If not OK, replace the faulty motor.
3. If the motor operates in both directions, check the operation of the window glass and lift
mechanism through its complete up and down travel.
There should be no binding or sticking of the window glass or lift mechanism through the entire
travel range.

Wiper Control Module: Description and Operation
FRONT WIPER MODULE
The wiper module is secured with screws through four rubber grommet-type insulators to the cowl
plenum panel and concealed within the cowl plenum area beneath the cowl plenum cover/grille
panel. The ends of the wiper pivot shafts that protrude through dedicated openings in the cowl
plenum cover/grille panel to drive the wiper arms and blades are the only visible components of the
wiper module. The wiper module consists of the following major components: Bracket - The wiper module bracket consists of a long tubular steel main member that has a
stamped pivot bracket formation near each end where the two wiper pivots are secured. A stamped
steel mounting plate for the wiper motor is secured with welds near the center of the main member.
- Crank Arm - The wiper motor crank arm is a stamped steel unit that has a slotted hole on the
driven end that is secured to the wiper motor output shaft with a nut, and has a ball stud secured to
the drive end.
- Linkage - The two wiper linkage members are each constructed of stamped steel. A driver side
drive link with a plastic socket-type bushing in the left end, and a plastic sleeve-type bushing in the
right end. Socket bushing is snap-fit over the pivot ball stud on the left pivot, while the sleeve
bushing is fit over the longer wiper motor crank arm pivot stud. The passenger side drive link has a
plastic socket-type bushing on each end. One end of this drive link is snap-fit over the pivot ball
stud on the right pivot, while the other end is snap-fit over the exposed end of the longer ball stud
on the wiper motor crank arm.
- Motor - The wiper motor is secured with three screws to the motor mounting plate near the center
of the wiper module bracket. The wiper motor output shaft passes through a hole in the module
bracket, where a nut secures the wiper motor crank arm to the motor output shaft. The two-speed
permanent magnet wiper motor features an integral transmission, an internal park switch, and an
internal Positive Temperature Coefficient (PTC) circuit breaker.
- Pivots - The two wiper pivots are secured to the ends of the wiper module bracket. The crank
arms that extend from the bottom of the pivot shafts each have a ball stud on their end. The upper
end of each pivot shaft where the wiper arms will be fastened each has an externally serrated drum
secured to it.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or
damaged, the entire wiper module unit must be replaced.
The wiper module operation is controlled by the vehicle operator through battery current inputs
received by the wiper motor from the multi-function switch on the steering column. The wiper motor
speed is controlled by current flow to either the low speed or the high speed set of brushes. The
park switch is a single pole, single throw, momentary switch within the wiper motor that is
mechanically actuated by the wiper motor transmission components. The park switch alternately
closes the wiper park switch sense circuit to ground or to battery current, depending upon the
position of the wipers on the glass. This feature allows the motor to complete its current wipe cycle
after the wiper system has been turned OFF, and to park the wiper blades in the lowest portion of
the wipe pattern. The automatic resetting circuit breaker protects the motor from overloads. The
wiper motor crank arm, the two wiper linkage members, and the two wiper pivots mechanically
convert the rotary output of the wiper motor to the back and forth wiping motion of the wiper arms
and blades on the glass.

Wiper Relay: Description and Operation
FRONT WIPER RELAY
The front wiper relay (or intermittent wipe relay) is located in the Power Distribution Center (PDC)
near the battery in the engine compartment. See the fuse and relay layout label affixed to the inside
surface of the PDC cover for front wiper relay identification and location. The front wiper relay is a
conventional International Standards Organization (ISO) micro relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. The relay is contained within a small, rectangular, molded plastic housing. The
relay is connected to all of the required inputs and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of the relay base. The ISO designation for each
terminal is molded into the base adjacent to the terminal. The ISO terminal designations are as
follows: 30 (Common Feed) - This terminal is connected to the movable contact point of the relay.
- 85 (Coil Ground) - This terminal is connected to the ground feed side of the relay control coil.
- 86 (Coil Battery) - This terminal is connected to the battery feed side of the relay control coil.
- 87 (Normally Open) - This terminal is connected to the normally open fixed contact point of the
relay.
- 87A (Normally Closed) - This terminal is connected to the normally closed fixed contact point of
the relay.
The front wiper relay cannot be adjusted or repaired. If the relay is damaged or faulty, it must be
replaced.
The front wiper relay (or intermittent wipe relay) is an electromechanical switch that uses a low
current input from the Central Timer Module ( CTM) to control a high current output to the low
speed brush of the front wiper motor. The movable common feed contact point is held against the
fixed normally closed contact point by spring pressure. When the relay coil is energized, an
electromagnetic field is produced by the coil windings. This electromagnetic field draws the
movable relay contact point away from the fixed normally closed contact point, and holds it against
the fixed normally open contact point. When the relay coil is de-energized, spring pressure returns
the movable contact point back against the fixed normally closed contact point. A resistor or diode
is connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil
collapses.
The front wiper relay terminals are connected to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC). The inputs and outputs of the front wiper relay
include: The common feed terminal (30) is connected to the front wiper motor low speed brush through the
wiper control circuitry of the multi-function switch on the steering column. When the front wiper
relay is de-energized, the common feed terminal is connected to the front wiper park switch output
through the CTM on the front wiper park switch sense circuit. The front wiper park switch output
may be battery current (wipers are not parked), or ground (wipers are parked). When the front
wiper relay is energized, the common feed terminal of the relay is connected to battery current from
a fuse in the Junction Block (JB) through a fused ignition switch output (run-acc) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the front wiper relay based upon its programming, inputs from the front wiper and
washer control circuitry of the multi-function switch, and inputs from the front wiper motor park
switch. The coil battery terminal (86) is connected to battery current from a fuse in the Junction
Block (JB) through a fused ignition switch output (run-acc) circuit whenever the ignition switch is in
the ON or Accessory positions.
- The normally open terminal (87) is connected to battery current from a fuse in the Junction Block
(JB) through a fused ignition switch output (run-acc) circuit whenever the front wiper relay control
coil is energized by the CTM. This circuit provides fused ignition switch output (run-acc) current to
the front wiper motor low speed brush only when the front wiper relay control coil is energized.
- The normally closed terminal (87A) is connected to the output of the front wiper motor park switch
through the CTM on the front wiper park switch sense circuit. This circuit provides battery current
(wipers are not parked) or ground (wipers are parked) to the front wiper motor low speed brush
whenever the front wiper relay control coil is de-energized and the OFF position of the front wiper
control circuitry within the multi-function switch is selected.
The front wiper relay can be diagnosed using conventional diagnostic tools and methods.
REAR WIPER RELAY
The rear wiper relay is located in the Power Distribution Center (PDC) near the battery in the
engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC
cover for rear wiper relay identification and location. The rear wiper relay is a conventional
International Standards Organization (ISO) micro relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. The relay is contained within a small, rectangular, molded plastic housing. The
relay is connected to all of the required inputs and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of the relay base. The ISO designation for each
terminal is molded into the base adjacent to the terminal. The ISO terminal designations are as
follows: 30 (Common Feed) - This terminal is connected to the movable contact point of the relay.
- 85 (Coil Ground) - This terminal is connected to the ground feed side of the relay control coil.
- 86 (Coil Battery) - This terminal is connected to the battery feed side of the relay control coil.
- 87 (Normally Open) - This terminal is connected to the normally open fixed contact point of the
relay.
- 87A (Normally Closed) - This terminal is connected to the normally closed fixed contact point of
the relay.
The rear wiper relay cannot be adjusted or repaired. If the relay is damaged or faulty, it must be
replaced.
The rear wiper relay is an electromechanical switch that uses a low current input from the Central
Timer Module (CTM) to control a high current output to the rear wiper motor. The movable common
feed contact point is held against the fixed normally closed contact point by spring pressure. When
the relay coil is energized, an electromagnetic field is produced by the coil windings. This
electromagnetic field draws the movable relay

contact point away from the fixed normally closed contact point, and holds it against the fixed
normally open contact point. When the relay coil is de-energized, spring pressure returns the
movable contact point back against the fixed normally closed contact point. A resistor or diode is
connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil
collapses. The rear wiper relay terminals are connected to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC). The inputs and outputs of the rear wiper relay
include:
- The common feed terminal (30) is connected to the rear wiper motor through the rear wiper motor
control circuit to the rear wiper motor. When the rear wiper relay is de-energized, the common feed
terminal is connected to ground through a take out and eyelet terminal connector of the headlamp
and dash wire harness that is secured by a nut to a ground stud located on the left front fender
inner shield in the engine compartment near the battery. When the rear wiper relay is energized,
the common feed terminal of the relay is connected to battery current from a fuse in the Power
Distribution Center (PDC) through a fused B(+) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the rear
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the rear wiper relay based upon its programming, electronic wiper and washer switch
state message inputs from the heater-air conditioner control, and a hard wired input from the rear
wiper motor park switch.
- The coil battery terminal (86) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally open terminal (87) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally closed terminal (87A) is connected to ground through a take out and eyelet terminal
connector of the headlamp and dash wire harness that is secured by a nut to a ground stud located
on the left front fender inner shield in the engine compartment near the battery.
The rear wiper relay can be diagnosed using conventional diagnostic tools and methods.

Washer Fluid Level Switch: Description and Operation
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the
outboard side of the washer reservoir forward of the two washer pump/motors, in the right front
corner of the engine compartment. Only the molded plastic switch mounting flange and connector
receptacle are visible when the switch is installed in the reservoir. A short nipple formation extends
from the inner surface of the switch mounting flange, and a barb on the nipple near the switch
mounting flange is press-fit into a rubber grommet seal installed in the mounting hole of the
reservoir. A small plastic float pivots on the end of a bracket that extends from the switch nipple
formation. Within the float is a small magnet, which actuates the reed switch. The washer fluid level
switch cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced.
The washer fluid level switch uses a pivoting, oblong float to monitor the level of the washer fluid in
the washer reservoir. The float contains a small magnet. When the float pivots, the changing
proximity of its magnetic field will cause the contacts of the small, stationary reed switch to open or
close. When the fluid level in the washer reservoir is at or above the float level, the float moves to a
vertical position and the switch contacts open. When the fluid level in the washer reservoir falls
below the pivoting float, the float moves to a horizontal position and the switch contacts close. The
switch contacts are connected in series between ground and the washer fluid switch sense input of
the instrument cluster. The switch is connected to the vehicle electrical system through a dedicated
take out and connector of the headlamp and dash wire harness. The switch receives ground
through another take out of the headlamp and dash wire harness with a single eyelet terminal
connector that is secured under a nut to a ground stud located on the right front fender inner shield
in the engine compartment. The washer fluid level switch can be diagnosed using conventional
diagnostic tools and methods. (Refer to WASHER FLUID INDICATOR - DIAGNOSIS AND

Washer Fluid Level Indicator: Description and Operation
A washer fluid indicator is standard equipment on all instrument clusters. The washer fluid indicator
is located in the Information Center area of the instrument cluster to the right of center. The washer
fluid indicator consists of a stenciled cutout of the International Control and Display Symbol icon for
"Windshield Washer Fluid" in the opaque layer of the instrument cluster overlay. The dark outer
layer of the overlay prevents the indicator from being clearly visible when it is not illuminated. An
amber lens behind the cutout in the opaque layer of the overlay causes the icon to appear in amber
through the translucent outer layer of the overlay when it is illuminated from behind by a Light
Emitting Diode (LED) soldered onto the instrument cluster electronic circuit board. The washer fluid
indicator is serviced as a unit with the instrument cluster.
The washer fluid indicator gives an indication to the vehicle operator when the fluid level in the
washer fluid reservoir is low. This indicator is controlled by a transistor on the instrument cluster
electronic circuit board based upon cluster programming and a hard wired washer fluid level switch
input to the cluster. The washer fluid indicator Light Emitting Diode (LED) receives battery current
on the instrument cluster electronic circuit board through the fused ignition switch output (run-start)
circuit whenever the ignition switch is in the ON or Start positions; therefore, the indicator will
always be OFF when the ignition switch is in any position except ON or Start. The LED only
illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument
cluster will turn ON the washer fluid indicator for the following reasons:
- Bulb Test - Each time the ignition switch is turned to the ON position the indicator is illuminated
for about two seconds as a bulb test.
- Washer Fluid Level Switch Input - Immediately after the bulb test, if the cluster senses ground on
the washer fluid switch sense circuit for more than about thirty seconds, it turns ON the washer
fluid indicator. Any time after the bulb test, the cluster must sense ground on the washer fluid
switch sense circuit for more than about sixty seconds before it turns ON the indicator. Once
illuminated, the indicator will remain illuminated until the ignition switch is cycled and the cluster
senses an open circuit on the low washer fluid sense input. This strategy is intended to reduce the
effect that fluid sloshing within the washer reservoir can have on reliable indicator operation.
- Actuator Test - Each time the cluster is put through the actuator test, the indicator will be turned
ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED
and the cluster control circuitry.
The washer fluid level switch is connected in series between ground and the washer fluid switch
sense input to the instrument cluster. For more information on the washer fluid level switch, (Refer
to WASHER FLUID LEVEL SWITCH - OPERATION). For further diagnosis of the washer fluid
indicator or the instrument cluster circuitry that controls the indicator, (Refer to INSTRUMENT
CLUSTER - DIAGNOSIS AND TESTING). The washer fluid level switch input to the cluster can be
diagnosed using conventional diagnostic tools and methods.

Washer Fluid Level Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative washer fluid indicator condition. If the problem
being diagnosed is related to indicator accuracy, be certain to confirm that the problem is with the
indicator or washer fluid level switch input and not with a damaged or empty washer fluid reservoir,
or inoperative instrument cluster indicator control circuitry. Inspect the washer fluid reservoir for
proper fluid level and signs of damage or distortion that could affect washer fluid level switch
performance and perform the instrument cluster actuator test before you proceed with the following
diagnosis. If no washer fluid reservoir or instrument cluster control circuitry problem is found, the
following procedure will help to locate a short or open in the washer fluid switch sense circuit.

Washer Fluid Level Switch: Description and Operation
The washer fluid level switch is a single pole, single throw reed-type switch mounted on the
outboard side of the washer reservoir forward of the two washer pump/motors, in the right front
corner of the engine compartment. Only the molded plastic switch mounting flange and connector
receptacle are visible when the switch is installed in the reservoir. A short nipple formation extends
from the inner surface of the switch mounting flange, and a barb on the nipple near the switch
mounting flange is press-fit into a rubber grommet seal installed in the mounting hole of the
reservoir. A small plastic float pivots on the end of a bracket that extends from the switch nipple
formation. Within the float is a small magnet, which actuates the reed switch. The washer fluid level
switch cannot be adjusted or repaired. If faulty or damaged, the switch must be replaced.
The washer fluid level switch uses a pivoting, oblong float to monitor the level of the washer fluid in
the washer reservoir. The float contains a small magnet. When the float pivots, the changing
proximity of its magnetic field will cause the contacts of the small, stationary reed switch to open or
close. When the fluid level in the washer reservoir is at or above the float level, the float moves to a
vertical position and the switch contacts open. When the fluid level in the washer reservoir falls
below the pivoting float, the float moves to a horizontal position and the switch contacts close. The
switch contacts are connected in series between ground and the washer fluid switch sense input of
the instrument cluster. The switch is connected to the vehicle electrical system through a dedicated
take out and connector of the headlamp and dash wire harness. The switch receives ground
through another take out of the headlamp and dash wire harness with a single eyelet terminal

Description and Operation
Windshield Washer Hose: Description and Operation
FRONT WASHER HOSES/TUBES
The front washer plumbing consists of a small diameter rubber hose that is routed from the barbed
outlet nipple of the front washer pump/motor on the washer reservoir through the engine
compartment along the headlamp and dash wire harness near the right inner fender shield to the
dash panel. The front washer hose passes from the engine compartment into the cowl plenum area
through a dedicated hole with a rubber grommet near the right end of the cowl plenum panel.
Beneath the cowl plenum cover/grille panel, a molded plastic in-line fitting with barbed nipples joins
the engine compartment hose to a cowl plenum cover/grille panel hose. The cowl plenum
cover/grille panel hose is routed through locating clips molded to the underside of the cowl plenum
cover/grille panel to a molded plastic eye fitting with barbed nipples and an integral check valve
near the passenger side washer nozzle. Two hoses are then routed from the eye fitting through
additional locating clips on the underside of the cowl plenum cover/grille panel to the two washer
nozzles.
Washer hose is available for service only as roll stock, which must then be cut to length. The
molded plastic washer hose fittings cannot be repaired. If these fittings are faulty or damaged, they
must be replaced.
Washer fluid in the washer reservoir is pressurized and fed by the front washer pump/motor
through the front washer system plumbing and fittings to the two front washer nozzles. Whenever
routing the washer hose or a wire harness containing a washer hose, it must be routed away from
hot, sharp, or moving parts; and, sharp bends that might pinch the hose must be avoided.
REAR WASHER HOSES/TUBES
The rear washer plumbing consists of small diameter rubber hose, the molded plastic rear washer
system check valve, and numerous routing clips. The rear washer system engine compartment
hose is connected to the barbed outlet nipple of the rear washer pump/motor unit on the washer
reservoir and routed through the engine compartment along the headlamp and dash wire harness
near the right inner fender shield to the back of the right front wheel house. At the back of the right
front wheel house, the engine compartment hose is joined to the passenger compartment hose by
the molded plastic rear washer system check valve. The passenger compartment hose passes
through a hole with a rubber grommet in the dash panel into the passenger compartment. The
passenger compartment hose is then routed below the instrument panel, down the right cowl side
inner panel, and along the right side of the floor panel near the body wire harness to the right rear
wheel house. At the rear wheel house, the passenger compartment hose is routed up to the right
quarter inner panel and below the quarter glass opening to the D-pillar at the rear of the vehicle. At
the rear of the vehicle, the passenger compartment hose is routed up the D-pillar and along the
upper liftgate opening inner panel toward the left side of the vehicle. Near the center of the liftgate
opening the hose passes through a clearance hole in the liftgate opening inner panel and through a
rubber grommet in a hole in the upper liftgate opening outer panel to the outside of the vehicle.
From the outside of the vehicle, the hose passes through another hole with a rubber grommet into
the upper inner liftgate panel to the rear washer nozzle.
Washer hose is available for service only as roll stock, which must then be cut to length. The
molded plastic washer hose fittings and routing clips cannot be repaired. If these fittings or clips are
faulty or damaged, they must be replaced.
Washer fluid in the washer reservoir is pressurized and fed by the rear washer pump/motor through
the rear washer system plumbing and fittings to the rear washer nozzle on the liftgate outer panel
above the liftgate glass. Whenever routing the washer hose or a wire harness containing a washer
hose, it must be routed away from hot, sharp, or moving parts; and, sharp bends that might pinch
the hose must be avoided.

damaged, the entire washer pump/motor unit must be replaced.
The rear washer pump/motor unit is connected to the vehicle electrical system through a single
take out and two-cavity connector of the headlamp and dash wire harness. The rear washer
pump/motor is grounded at all times through a take out of the headlamp and dash wire harness
with a single eyelet terminal connector that is secured by a nut to a ground stud located on the right
front fender inner shield in the engine compartment. The rear washer pump/motor receives battery
current on a rear washer pump/ motor control circuit through an output of the air conditioner-heater
control whenever the momentary contacts of the rear washer switch within the air
conditioner-heater control are closed. Washer fluid is gravity-fed from the washer reservoir to the
inlet side of the washer pump. When the pump motor is energized, the rotor-type pump pressurizes
the washer fluid and forces it through the pump outlet nipple, the rear washer plumbing, and the
rear washer nozzle onto the liftgate glass.

Windshield Washer Reservoir: Description and Operation
Fig. 12 Washer Reservoir
A single washer fluid reservoir is used for both the front and rear washer systems. The molded
plastic washer fluid reservoir is integral to, and located on the right end of the upper radiator shroud
in the right front corner of the engine compartment. A bright yellow plastic filler cap with a rubber
seal and an International Control and Display Symbol icon for "Windshield Washer" and the text
"Washer Fluid Only" molded into it snaps over the open end of the filler neck. The cap hinges on
and is secured to a molded-in hook formation on the top of the reservoir just inboard of the filler
neck when it is removed for inspecting or adjusting the fluid level in the reservoir. There are
separate, dedicated holes on the outboard side of the reservoir provided for the mounting of the
front and rear washer/pump motor units and the washer fluid level switch.
The washer reservoir is serviced only as a unit with the upper radiator shroud. The washer
reservoir cannot be repaired and, if faulty or damaged, the upper fan shroud unit must be replaced.
The grommet seals for the washer pump/motor units and the washer fluid level switch, and the filler
cap are each available for service replacement.
The washer fluid reservoir provides a secure, on-vehicle storage location for a large reserve of
washer fluid for operation of the front and rear washer systems. The washer reservoir filler neck
provides a clearly marked and readily accessible point from which to add washer fluid to the
reservoir. The front and rear washer/pump motor units are located in a sump area near the bottom
of the reservoir to be certain that washer fluid will be available to the pump as the fluid level in the
reservoir becomes depleted. The front washer pump/motor unit is mounted in the lowest position in
the sump so that the front washers will operate even after the rear washer system will no longer
operate. The washer fluid level switch is mounted just above the sump area of the reservoir so that
there will be adequate warning to the vehicle operator that the washer fluid level is low, before the
washer system will no longer operate.

Wiper Arm: Description and Operation
FRONT WIPER ARM
The front wiper arms are the rigid members located between the wiper pivots that protrude from the
cowl plenum cover/grille panel near the base of the windshield and the wiper blades on the
windshield glass. These wiper arms feature an over-center hinge that allows easy access to the
windshield glass for cleaning. The wiper arm has a die cast metal pivot end with a large mounting
hole with internal serrations at one end. A molded black plastic cap fits over the wiper arm retaining
nut to conceal the nut and this mounting hole following wiper arm installation. The wide end of a
tapered, stamped steel channel hinges on and is secured with a hinge pin to the blade end of the
wiper arm pivot end. One end of a long, rigid, stamped steel strap, with a small hole near its pivot
end, is riveted and crimped within the narrow end of the stamped steel channel. The tip of the wiper
blade end of this strap is bent back under itself to form a small hook. Concealed within the stamped
steel channel, one end of a long spring is engaged with a wire hook on the underside of the die
cast pivot end, while the other end of the spring is hooked through the small hole in the steel strap.
The entire wiper arm has a satin black finish applied to all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If damaged or faulty, the entire wiper arm unit must be
replaced.
The front wiper arms are designed to mechanically transmit the motion from the wiper pivots to the
wiper blades. The wiper arm must be properly indexed to the wiper pivot in order to maintain the
proper wiper blade travel on the glass. The mounting hole formation with internal serrations in the
wiper arm pivot end interlocks with the serrations on the outer circumference of the wiper pivot
driver, allowing positive engagement and finite adjustment of this connection. The mounting nut
locks the wiper arm to the threaded stud on the wiper pivot. The spring-loaded wiper arm hinge
controls the down-force applied through the tip of the wiper arm to the wiper blade on the glass.
The hook formation on the tip of the wiper arm provides a cradle for securing and latching the wiper
blade pivot block to the wiper arm.

DISCUSSION:
Windshield wiper blades/elements are frequently replaced unnecessarily. Because of the
environmental conditions vehicles can be operated in, a film can build up on both the windshield
and the windshield wiper elements that will cause poor cleaning/streaking of the windshield, and in
some instances, a chattering condition as the wipers blades travel across the windshield.
Replacement of the wiper blades/elements is normally NOT required to correct streaking issues. A
simple NORMAL MAINTENANCE cleaning of the wiper blades/elements and windshield is all that
is required.
If the wipe pattern appears to be streaky or if there is chatter and no damage to the wiper
blades/elements is obvious, the following steps should be performed:
1. Use a soft cloth or sponge & squeegee and MOPAR Windshield Washer Solvent (p/n
04318067AB, 16 Oz. bottle or p/n 04318068AB, 32 Oz. bottle), MOPAR Glass Cleaner (p/n

2. Raise the wiper blades off the glass and clean the wiper blade elements (rubber insert) with
MOPAR Windshield Washer Solvent or a solution of 50/50 alcohol and water and a soft cloth,
paper towel or sponge.
3. Return the wiper blades to their normal operating position and function the washer system. If the
wiper blades/elements are not streaking the windshield or chattering, replacing the blade
assembly(ies) is not necessary. If the wipe pattern is still objectionable, repeat step 2 several times.
If the wipe pattern is still objectionable, replace the wiper blades/elements.

Wiper Blade: Description and Operation
FRONT WIPER BLADE
Each wiper blade is secured by an integral latching pivot block to the hook formation on the tip of
the wiper arms, and rests on the glass near the base of the windshield when the wipers are not in
operation. The wiper blade consists of the following components: Superstructure - The superstructure includes several stamped steel bridges and links with claw
formations that grip the wiper blade element. The driver side and passenger side wiper blades are
not interchangeable. The superstructure of the driver side blade features an additional bridge,
which provides an additional set of claws to retain the wiper squeegees. Their are eight sets of
claws on the driver side, and six sets of claws used on the passenger side. Also included in this
unit is the latching, molded plastic pivot block that secures the super- structure to the wiper arm. All
of the metal components of the wiper blade have a satin black finish applied.
- Element - The wiper element or squeegee is the resilient rubber member of the wiper blade that
contacts the glass.
- Flexor - The flexor is a rigid metal component running along the length of each side of the wiper
element where it is gripped by the claws of the superstructure.
All Durango models have two 50 centimeter (19.69 inch) wiper blades with non-replaceable rubber
elements (squeegees). These wiper blades also include an anti-lift feature. The wiper blades
cannot be adjusted or repaired. If faulty, worn, or damaged the entire wiper blade unit must be
replaced.
The wiper blades are moved back and forth across the glass by the wiper arms when the wipers
are being operated. The wiper blade superstructure is the flexible frame that grips the wiper blade
element and evenly distributes the force of the spring-loaded wiper arm along the length of the
element. The combination of the wiper arm force and the flexibility of the superstructure makes the
element conform to and maintain proper contact with the glass, even as the blade is moved over
the varied curvature found across the glass surface. The wiper element flexor provides the claws of
the blade superstructure with a rigid, yet flexible component on the element which can be gripped.
The rubber element is designed to be stiff enough to maintain an even cleaning edge as it is drawn
across the glass, but resilient enough to conform to the glass surface and flip from one cleaning
edge to the other each time the wiper blade changes directions.
Fig. 10 Rear Wiper Blade
REAR WIPER BLADE
The rear wiper blade is secured by an integral latching pivot block to the hook formation on the tip
of the rear wiper arm, and rests on the glass near the base of the liftgate glass when the wiper is
not in operation. The rear wiper blade consists of the following components: Superstructure - The superstructure includes a stamped steel bridge and plastic links with claw
formations that grip the wiper blade element. Also included in this unit is the latching, molded
plastic pivot block that secures the superstructure to the wiper arm. All of the metal components of
the wiper blade have a satin black finish applied.
- Element - The wiper element or squeegee is the resilient rubber member of the wiper blade that
contacts the glass.
- Flexor - The flexor is a rigid metal component running along the length of each side of the wiper
element where it is gripped by the claws of the superstructure.
All Durango models with the rear wiper and washer system have one 40.0-centimeter (15.75-inch)
rear wiper blade with a non-replaceable element (squeegee). The wiper blade cannot be adjusted
or repaired. If faulty, worn, or damaged the entire wiper blade unit must be replaced.
The rear wiper blade is moved back and forth across the glass by the wiper arm when the rear
wiper system is in operation. The wiper blade

Bulletins > Page 8049
superstructure is the flexible frame that grips the wiper blade element and evenly distributes the
force of the spring-loaded wiper arm along the length of the element. The combination of the wiper
arm force and the flexibility of the superstructure makes the element conform to and maintain
proper contact with the liftgate glass, even as the blade is moved over the varied curvature found
across the glass surface. The wiper element flexor provides the claws of the blade superstructure
with a rigid, yet flexible component on the element which can be gripped. The rubber element is
designed to be stiff enough to maintain an even cleaning edge as it is drawn across the glass, but
resilient enough to conform to the glass surface and flip from one cleaning edge to the other each
time the wiper blade changes directions.

and Operation
Wiper Control Module: Description and Operation
FRONT WIPER MODULE
The wiper module is secured with screws through four rubber grommet-type insulators to the cowl
plenum panel and concealed within the cowl plenum area beneath the cowl plenum cover/grille
panel. The ends of the wiper pivot shafts that protrude through dedicated openings in the cowl
plenum cover/grille panel to drive the wiper arms and blades are the only visible components of the
wiper module. The wiper module consists of the following major components: Bracket - The wiper module bracket consists of a long tubular steel main member that has a
stamped pivot bracket formation near each end where the two wiper pivots are secured. A stamped
steel mounting plate for the wiper motor is secured with welds near the center of the main member.
- Crank Arm - The wiper motor crank arm is a stamped steel unit that has a slotted hole on the
driven end that is secured to the wiper motor output shaft with a nut, and has a ball stud secured to
the drive end.
- Linkage - The two wiper linkage members are each constructed of stamped steel. A driver side
drive link with a plastic socket-type bushing in the left end, and a plastic sleeve-type bushing in the
right end. Socket bushing is snap-fit over the pivot ball stud on the left pivot, while the sleeve
bushing is fit over the longer wiper motor crank arm pivot stud. The passenger side drive link has a
plastic socket-type bushing on each end. One end of this drive link is snap-fit over the pivot ball
stud on the right pivot, while the other end is snap-fit over the exposed end of the longer ball stud
on the wiper motor crank arm.
- Motor - The wiper motor is secured with three screws to the motor mounting plate near the center
of the wiper module bracket. The wiper motor output shaft passes through a hole in the module
bracket, where a nut secures the wiper motor crank arm to the motor output shaft. The two-speed
permanent magnet wiper motor features an integral transmission, an internal park switch, and an
internal Positive Temperature Coefficient (PTC) circuit breaker.
- Pivots - The two wiper pivots are secured to the ends of the wiper module bracket. The crank
arms that extend from the bottom of the pivot shafts each have a ball stud on their end. The upper
end of each pivot shaft where the wiper arms will be fastened each has an externally serrated drum
secured to it.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or
damaged, the entire wiper module unit must be replaced.
The wiper module operation is controlled by the vehicle operator through battery current inputs
received by the wiper motor from the multi-function switch on the steering column. The wiper motor
speed is controlled by current flow to either the low speed or the high speed set of brushes. The
park switch is a single pole, single throw, momentary switch within the wiper motor that is
mechanically actuated by the wiper motor transmission components. The park switch alternately
closes the wiper park switch sense circuit to ground or to battery current, depending upon the
position of the wipers on the glass. This feature allows the motor to complete its current wipe cycle
after the wiper system has been turned OFF, and to park the wiper blades in the lowest portion of
the wipe pattern. The automatic resetting circuit breaker protects the motor from overloads. The
wiper motor crank arm, the two wiper linkage members, and the two wiper pivots mechanically
convert the rotary output of the wiper motor to the back and forth wiping motion of the wiper arms
and blades on the glass.

Fig. 12 Rear Wiper Motor
REAR WIPER MOTOR
The rear wiper motor is concealed within the liftgate, below the liftgate glass and behind the liftgate
trim panel. The end of the motor output shaft that protrudes through the liftgate outer panel to drive
the rear wiper arm and blade is the only visible component of the rear wiper motor. A rubber bezel
and grommet is secured with a nut to the motor output shaft to seal and secure the unit to the
liftgate outer panel, and a plastic nut cover snaps over the top of the bezel for a neat appearance.
The rear wiper motor consists of the following major components: Bracket - The rear wiper motor bracket consists of a stamped steel mounting plate for the wiper
motor that is secured with screws to the wiper motor housing, and through two rubber
grommet-type insulators to the liftgate inner panel.
- Motor - The single-speed permanent magnet rear wiper motor is secured with screws to the rear
wiper module bracket. The wiper motor includes an integral transmission, a motor output shaft, an
automatic re-setting circuit breaker, and the rear wiper motor park switch.
The rear wiper motor cannot be adjusted or repaired. If any component of the motor is faulty or
damaged, the entire rear wiper motor unit must be replaced. The motor output shaft bezel and
grommet, nut, and nut cap are available for service replacement.
The rear wiper motor operation is controlled by the rear wiper relay, which controls battery current
flow to the rear wiper motor brushes based upon control outputs from the Central Timer Module
(CTM). The CTM uses internal programming, hard wired outputs from the rear wiper motor park
switch, and electronic messages received over the Programmable Communications Interface (PCI)
data bus network from the rear wiper and washer switches in the air conditioner-heater control to
determine when to energize or de-energize the rear wiper relay. The rear wiper motor park switch
is a single pole, single throw, momentary switch within the wiper motor that is mechanically
actuated by the wiper motor transmission components. The park switch alternately closes and
opens a path to ground for the rear wiper motor control circuit input to the CTM, depending upon
the position of the rear wiper blade on the liftgate glass. This feature allows the CTM to monitor the
number of rear wiper motor cycles, as well as to keep the rear wiper relay energized long enough
for the motor to complete its current wipe cycle after the wiper system or the ignition has been
turned OFF, and to park the wiper blade in the lowest portion of the wipe pattern. The rear wiper
motor is grounded at all times through a take out with an eyelet terminal connector in the body wire
harness that is secured by a nut to a ground stud located on the lower left D-pillar in the passenger
compartment. The automatic resetting circuit breaker protects the motor from overloads. The rear
wiper motor transmission converts the rotary output of the wiper motor to the back and forth wiping
motion of the rear wiper arm and blade on the liftgate glass.

Wiper Relay: Description and Operation
FRONT WIPER RELAY
The front wiper relay (or intermittent wipe relay) is located in the Power Distribution Center (PDC)
near the battery in the engine compartment. See the fuse and relay layout label affixed to the inside
surface of the PDC cover for front wiper relay identification and location. The front wiper relay is a
conventional International Standards Organization (ISO) micro relay. Relays conforming to the ISO
specifications have common physical dimensions, current capacities, terminal patterns, and
terminal functions. The relay is contained within a small, rectangular, molded plastic housing. The
relay is connected to all of the required inputs and outputs through its PDC receptacle by five male
spade-type terminals that extend from the bottom of the relay base. The ISO designation for each
terminal is molded into the base adjacent to the terminal. The ISO terminal designations are as
follows: 30 (Common Feed) - This terminal is connected to the movable contact point of the relay.
- 85 (Coil Ground) - This terminal is connected to the ground feed side of the relay control coil.
- 86 (Coil Battery) - This terminal is connected to the battery feed side of the relay control coil.
- 87 (Normally Open) - This terminal is connected to the normally open fixed contact point of the
relay.
- 87A (Normally Closed) - This terminal is connected to the normally closed fixed contact point of
the relay.
The front wiper relay cannot be adjusted or repaired. If the relay is damaged or faulty, it must be
replaced.
The front wiper relay (or intermittent wipe relay) is an electromechanical switch that uses a low
current input from the Central Timer Module ( CTM) to control a high current output to the low
speed brush of the front wiper motor. The movable common feed contact point is held against the
fixed normally closed contact point by spring pressure. When the relay coil is energized, an
electromagnetic field is produced by the coil windings. This electromagnetic field draws the
movable relay contact point away from the fixed normally closed contact point, and holds it against
the fixed normally open contact point. When the relay coil is de-energized, spring pressure returns
the movable contact point back against the fixed normally closed contact point. A resistor or diode
is connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil
collapses.
The front wiper relay terminals are connected to the vehicle electrical system through a connector
receptacle in the Power Distribution Center (PDC). The inputs and outputs of the front wiper relay
include: The common feed terminal (30) is connected to the front wiper motor low speed brush through the
wiper control circuitry of the multi-function switch on the steering column. When the front wiper
relay is de-energized, the common feed terminal is connected to the front wiper park switch output
through the CTM on the front wiper park switch sense circuit. The front wiper park switch output
may be battery current (wipers are not parked), or ground (wipers are parked). When the front
wiper relay is energized, the common feed terminal of the relay is connected to battery current from
a fuse in the Junction Block (JB) through a fused ignition switch output (run-acc) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the front wiper relay based upon its programming, inputs from the front wiper and
washer control circuitry of the multi-function switch, and inputs from the front wiper motor park
switch. The coil battery terminal (86) is connected to battery current from a fuse in the Junction
Block (JB) through a fused ignition switch output (run-acc) circuit whenever the ignition switch is in
the ON or Accessory positions.
- The normally open terminal (87) is connected to battery current from a fuse in the Junction Block
(JB) through a fused ignition switch output (run-acc) circuit whenever the front wiper relay control
coil is energized by the CTM. This circuit provides fused ignition switch output (run-acc) current to
the front wiper motor low speed brush only when the front wiper relay control coil is energized.
- The normally closed terminal (87A) is connected to the output of the front wiper motor park switch
through the CTM on the front wiper park switch sense circuit. This circuit provides battery current
(wipers are not parked) or ground (wipers are parked) to the front wiper motor low speed brush
whenever the front wiper relay control coil is de-energized and the OFF position of the front wiper
control circuitry within the multi-function switch is selected.
The front wiper relay can be diagnosed using conventional diagnostic tools and methods.
REAR WIPER RELAY
The rear wiper relay is located in the Power Distribution Center (PDC) near the battery in the
engine compartment. See the fuse and relay layout label affixed to the inside surface of the PDC
cover for rear wiper relay identification and location. The rear wiper relay is a conventional

contact point away from the fixed normally closed contact point, and holds it against the fixed
normally open contact point. When the relay coil is de-energized, spring pressure returns the
movable contact point back against the fixed normally closed contact point. A resistor or diode is
connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as the electromagnetic field of the relay coil

receptacle in the Power Distribution Center (PDC). The inputs and outputs of the rear wiper relay
include:
- The common feed terminal (30) is connected to the rear wiper motor through the rear wiper motor
control circuit to the rear wiper motor. When the rear wiper relay is de-energized, the common feed
terminal is connected to ground through a take out and eyelet terminal connector of the headlamp
and dash wire harness that is secured by a nut to a ground stud located on the left front fender
inner shield in the engine compartment near the battery. When the rear wiper relay is energized,
the common feed terminal of the relay is connected to battery current from a fuse in the Power
Distribution Center (PDC) through a fused B(+) circuit.
- The coil ground terminal (85) is connected to the relay control output of the CTM through the rear
wiper relay control circuit. The CTM controls the ground path for this circuit internally to energize or
de-energize the rear wiper relay based upon its programming, electronic wiper and washer switch
state message inputs from the heater-air conditioner control, and a hard wired input from the rear
wiper motor park switch.
- The coil battery terminal (86) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally open terminal (87) is connected to battery current from a fuse in the PDC through a
fused B(+) circuit at all times.
- The normally closed terminal (87A) is connected to ground through a take out and eyelet terminal
connector of the headlamp and dash wire harness that is secured by a nut to a ground stud located
on the left front fender inner shield in the engine compartment near the battery.

replace the faulty relay.
Relay Circuit Test
1. The relay common feed terminal cavity (30) is connected to the multi-function switch. There
should be continuity between the receptacle for
terminal 30 of the rear wiper relay in the PDC and the rear wiper motor control circuit cavity of the
liftgate wire harness connector for the rear wiper motor at all times. If OK, go to Step 2. If not OK,
repair the open rear wiper motor control circuit between the PDC and the rear wiper motor as
required.
2. The relay normally closed terminal (87A) is connected to ground. There should be continuity
between the receptacle for terminal 87A of the rear
wiper relay in the PDC and a good ground at all times. If OK, go to Step 3. If not OK, repair the
open ground circuit to ground (G113) as required.
3. The relay normally open terminal (87) is connected to a fused B(+) fuse in the PDC through a
fused B(+) circuit. There should be battery voltage
at the receptacle for terminal 87 of the rear wiper relay at all times. If OK, go to Step 4. If not OK,
repair the open B(+) circuit between the PDC and the battery as required.
4. The coil battery terminal (86) is connected to a fused B(+) fuse in the PDC through a fused B(+)
circuit. There should be battery voltage at the
receptacle for terminal 86 of the rear wiper relay at all times. If OK, go to Step 5. If not OK, repair
the open B(+) circuit between the PDC and the battery as required.
5. The coil ground terminal (85) is connected to the output of the Central Timer Module (CTM)
through the rear wiper relay control circuit. There
should be continuity between the receptacle for terminal 85 of the rear wiper relay in the PDC and
the rear wiper relay control circuit cavity of the instrument panel wire harness connector (Connector
C3) for the CTM at all times. If not OK, repair the open rear wiper relay control circuit between the
PDC and the CTM as required.
