CAUTION: Use care when removing or installing instrument cluster bezel
so as not to damage trip odometer reset button. If trip
odometer reset button is damaged, instrument cluster must be
replaced.
Removal & Installation (Ram Van/Wagon)
1) Disconnect negative battery cable. Remove engine cover
from passenger compartment. Reach between upper dash panel engine
housing extension and bottom of instrument panel. Disconnect vacuum
harness connector located near left defroster outlet of distribution
duct.
2) On models equipped with A/T, unlock ignition switch. Set
parking brake and place gear selector lever in "L" position. If
equipped, set tilt steering column in lowest position. Carefully pry
bezel away from instrument panel to disengage clips. Pull bezel away
far enough to clear trip odometer reset button. Remove bezel.
3) Remove 3 bolts from heater control panel. Pull heater
control panel outward enough to disconnect electrical connectors and

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

cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION.
Reconnect negative battery cable. Measure voltage between ground and
terminal No. 6 (Pink/White wire) of instrument cluster connector C1.
See Fig. 1 . If battery voltage is present, reinstall instrument
cluster and go to SELF- DIAGNOSTICS. If battery voltage is not
present, repair open circuit between fuse No. 12 (15-amp) in junction
block and instrument cluster connector C1 and go to next step.
5) Remove and inspect fuse No. 11 (10-amp) in junction block\
.
If fuse is okay, go to next step. If fuse is blown, locate and repair
cause of blown fuse. Install new fuse and recheck system operation.
6) Turn ignition on. Measure voltage between ground and power
side (Dark Blue/White wire) of fuse No. 11 (10-amp) in junction bloc\
k.
If battery voltage is present, go to step 8). If battery voltage is
not present, locate and repair open circuit to fuse No. 11. See WIRING
DIAGRAMS.
7) Turn ignition off and disconnect negative battery cable.
Install instrument cluster. Connect negative battery cable. Turn
ignition on. Set parking brake and observe instrument cluster brake
warning light. If brake warning light is on, go to next step. If brake
warning light is off, go to step 9).
8) Turn ignition off. Turn parking lights on and adjust
instrument panel lights dimmer rheostat to full bright position. If
instrument panel lights are on, go to step 10). If instrument panel
lights are off, repair instrument cluster illumination ground circuit
between instrument cluster connector C2 terminal No. 7 (Black wire)
and ground. See WIRING DIAGRAMS.
9) Turn ignition off and disconnect negative battery cable.
Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL &
INSTALLATION. Connect negative battery cable. Turn ignition on.
Measure voltage between ground and terminal No. 2 (Dark Blue/White
wire) at instrument cluster connector C1. If battery voltage is
present, go to SELF-DIAGNOSTICS. If battery voltage is not present,
repair open circuit between junction block fuse No. 11 and instrument
cluster.
10) Turn ignition off and disconnect negative battery cable.
Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL &
INSTALLATION. Check continuity between ground and terminal No. 4
(Black/Dark Green wire) at instrument cluster connector C1. If
continuity exists, go to SELF-DIAGNOSTICS. If continuity does not
exist, locate and repair open in ground circuit.
SELF-DIAGNOSTICS
1) With ignition off, press and hold trip odometer RESET
button while turning ignition switch to ON position. Continue to hold
RESET button until odometer window displays CHEC (about 10 seconds).
Release RESET button. If problem exists, system will display
Diagnostic Trouble Codes (DTC). See DIAGNOSTIC CODE CHART table. For
repairs of DTCs, see appropriate BODY CONTROL COMPUTER TESTS article.
