DESCRIPTION & OPERATION
INSTRUMENT CLUSTER
All instrument cluster gauges are air core magnetic type.
Tachometer is optional. All gauges use data transferred on Chrysler
Collision Detection (CCD) bus. Instrument cluster incorporates a
Vacuum Fluorescent Display (VFD) for odometer display.
Brake warning light illuminates when ignition is on and
parking brake is applied. Brake warning light also illuminates if
brake hydraulic system failure occurs during service brake
application. Brake warning light bulb test occurs when ignition switch
is in START position.
Oil pressure warning light illuminates when engine oil
pressure is not sufficient to open oil pressure sending unit switch.
Oil pressure warning light bulb test occurs with ignition switch in
RUN position.
All instrument clusters include these analog gauges:
* Coolant Temperature Gauge
* Fuel Gauge
* Oil Pressure Gauge
* Speedometer
* Voltmeter
Instrument clusters include these indicator lights, if
vehicle is equipped with appropriate option:
* Air Bag
* Anti-Lock Brake System (ABS)
* Brake Warning
* Check Gauges
* Cruise On
* Headlight High Beam
* Low Fuel
* Low Washer Fluid
* CHECK ENGINE
* Overdrive Off
* Rear Wheel Anti-Lock (RWAL)
* Seat Belt Reminder
* Security
* Transmission Oil Temperature (A/T)
* Turn Signal
* Upshift (M/T)
* 4WD
SELF-DIAGNOSTIC SYSTEM
WARNING: Vehicle is equipped with an air bag system. To prevent air
bag deployment, disconnect negative battery cable and wait at
least 2 minutes before servicing instrument cluster. See
appropriate AIR BAG RESTRAINT SYSTEMS article.
CAUTION: When battery is disconnected, vehicle computer and memory

2) Apply voltage to Light Blue/Yellow wire at heated mirror
and ground Black wire at heated mirror. Mirror should become warm to
touch. If mirror is not warm to touch, remove mirror and test wires
for continuity. If no continuity exists, repair wires. If wires are
okay, replace mirror. To test defogger switch, see appropriate wiring
diagram in REAR WINDOW DEFOGGERS article.
NOTE: On Ram Pickup, heated mirror is controlled by mirror defogger
switch.
Ram Pickup
1) Turn ignition on. While watching instrument panel
voltmeter, turn heated mirror switch on. Voltmeter needle should
deflect. With heated mirror on, mirror should be warm to touch after
3-4 minutes. If system operates as described, system is okay at this
time.
2) If system does not operate as described, go to next step.
Illuminated indicator light means only that voltage exists at heated
mirror relay.
3) Ensure ignition is on. Check fuses in Power Distribution
Center (PDC) and junction block. Ensure fuses are fully seated and
connections are secure. If mirrors are still inoperative, problem is
in heated mirror control, mirror heating grid and/or heated mirror
harness or connectors. If turning switch on causes a large deflection
in instrument panel voltmeter, check for a short circuit in system.
Repair as necessary.
REMOVAL & INSTALLATION
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
HEATED MIRROR SWITCH
Removal & Installation (Ram Pickup)
Heated mirror switch is part of HVAC control unit. See
appropriate AUTOMATIC A/C-HEATER SYSTEMS article in appropriate AIR
CONDITIONING & HEATING SERVICE & REPAIR section.

switch connector. See Fig. 4. If continuity does not exist, repair
open Black/Red wire. If continuity exists, go to next step.
3) Check continuity between ground and Black/Red wire at
steering column horn switch connector. If continuity does not exist,
go to next step. If continuity exists, repair short to ground in
Black/Red wire.
4) Continuity between horn switch terminal and ground.
Continuity should exist with horn switch depressed. Continuity should
not exist without horn switch depressed. If continuity is not as
specified, replace horn switch. If continuity is as specified, install
horn relay and go to HORN under COMPONENT TESTS.
TURN SIGNAL & HAZARD WARNING SYSTEMS
1) If bulbs burn out rapidly, check charging system for
overcharging condition. See appropriate GENERATORS & REGULATORS
article in STARTING & CHARGING SYSTEMS. If charging system is okay, go
to next step. If charging system is not okay, repair as necessary.
2) If problem is turn signals failing to cancel after a turn,
inspect multifunction switch or cancelling cam lobes on clockspring
for damage or improper installation. If problem exists, repair as
necessary. If problem does not exist, go to next step.
3) Turn ignition on. Actuate turn signal switch or hazard
warning switch. Observe turn signal indicator light(s) in instrument
cluster. If flash rate is very high, check for a bulb that is not lit
or is dimly lit. Repair circuit or replace bulb as necessary. If turn
signals fail to light, go to next step.
4) Turn ignition off. Check turn signal fuse in junction
block and/or hazard warning fuse in PDC. If fuses are okay, go to next
step. If either fuse is blown, repair short circuit and replace fuse.
5) Check for battery voltage at hazard warning fuse in PDC.
Turn ignition on. Check for battery voltage at turn signal fuse in
junction block. If battery voltage exists, go to next step. If battery
voltage does not exist, repair open circuit to battery or ignition
switch as necessary.
6) Turn ignition off. Disconnect negative battery cable.
Remove combination flasher from junction block and replace with a
known good unit. Connect battery cable and test operation of turn
signal and hazard warning systems. If operation is okay, discard
faulty flasher. If operation is not okay, go to next step.
7) Turn ignition on. Check for battery voltage at combination
flasher terminals No. 51 and 48 in junction block. If battery voltage
exists, go to next step. If battery voltage does not exist, repair
open circuit to fuse in junction block or PDC as necessary.
8) Disconnect negative battery cable. Check continuity
between combination flasher terminal No. 50 and ground. If continuity
exists, go to next step. If continuity does not exist, repair open
ground circuit.
9) Disconnect multifunction switch harness connector. Check
continuity between junction block terminal No. 4 and multifunction
switch terminal No. 13 (Pink wire). If continuity exists, go to next
step. If continuity does not exist, repair open in Pink wire between
multifunction switch and junction block.
10) Check continuity between junction block terminal No. 13
and multifunction switch terminal No. 17 (Red/White wire). If
continuity exists, test multifunction switch. See MULTIFUNCTION SWITCH
under COMPONENT TESTS. If continuity does not exist, repair open in
Red/White wire between junction block and multifunction switch.

INTRODUCTION
Before diagnosing symptoms or intermittent faults, perform
basic diagnostic procedures in the appropriate BASIC DIAGNOSTIC
PROCEDURES article and applicable self-diagnostic tests in the
appropriate SELF-DIAGNOSTICS article. Use this article to diagnose
driveability problems existing when a hard fault code is not present.
NOTE: Some driveability problems may have been corrected by
manufacturer with a revised Powertrain Control Module (PCM).
Check with manufacturer for latest PCM application.
Symptom checks direct the technician to malfunctioning
component(s) for further diagnosis. A symptom should lead to a
specific component, system test or adjustment.
Use intermittent test procedures to locate driveability
problems that do not occur when the vehicle is being tested. These
problems may cause a noticeable driveability problem or cause the
Malfunction Indicator Light (MIL) to illuminate on some vehicles.
These test procedures should also be used if a soft (intermittent)
trouble code is present, but no problem is found during self-
diagnostic testing.
NOTE: For specific testing procedures, see appropriate SELF
-DIAGNOSTICS article. For specifications, see appropriate ON
-VEHICLE ADJUSTMENTS and SERVICE & ADJUSTMENT SPECIFICATIONS
articles.
SYMPTOMS
SYMPTOM DIAGNOSIS
Symptom checks cannot be used properly unless the problem
occurs while the vehicle is being tested. To reduce diagnostic time,
ensure basic diagnostic procedures and self-diagnostic were performed
before diagnosing a symptom. Symptoms available for diagnosis are as
follows:
* Hard Start
* Starts But Stalls
* Hesitation Or Stumble
* Surging
* Lack Of Power
* Knocking
* Engine Misfire
* Backfire
* Rough Or Erratic Idle
* Poor Fuel Economy
HARD START
