GENERAL INFORMATION
MECHANICAL CLUSTER
The mechanical cluster includes a fuel, oil pres-
sure, coolant temperature, and voltmeter gauges. All
incorporate magnetic type gauges. When the ignition
switch is in the OFF position, the gauges will show a
reading; however, the readings are only accurate
when the ignition switch is in the ON position. The mechanical cluster also includes an electric
speedometer, driven by pulses from the vehicle speed
sensor (Fig. 1).
ELECTRONIC CLUSTER
The electronic cluster is easily distinguished from
the mechanical cluster by its digital and linear dis-
play. The electronic cluster includes:
² Oil pressure gauge
² Coolant temperature gauge
² Voltmeter
² Fuel gauge
The electronic cluster receives virtually all of its
information to display from the body controller and
powertrain control module via the Chrysler Collision
Detection (CCD) Serial Data Bus. The odometer
memory is no longer retained in the cluster. This is
now retained in the body controller (Fig. 2).
ELECTRONIC CLUSTER DIMMING
The electronic cluster display is dimmed from day-
time to night time intensity when the headlamp
switch is turned on. This intensity can be controlled
using the headlamp switch rheostat. An additional detent on the headlamp switch rheo-
stat will allow daytime intensity while driving with
headlamps on during the daytime.
WARNING LAMPS
The mechanical instrument cluster will have warn-
ing lamps for six systems. These include brake sys-
tem, air bag, seat belt, low fuel, anti-lock for optional
anti-lock brake system, and malfunction indicator
(check engine) lamp. The cluster also includes check
gages indicator which will illuminate in a warning
situation. This will notify driver to check for a prob-
lem in coolant temperature, oil pressure, or electrical
systems. The electronic cluster will have warning indicator
lamps for eight different systems. These include:
² Air Bag
² Low washer fluid
² Door/deck lid ajar
² Malfunction Indicator (Check engine) Lamp
² Brake system
² Seat belt
² Anti-lock (ABS) for optional anti-lock brake sys-
tem
² Check gages, monitors engine coolant, oil pressure
and electrical charging system failures. In addition, ISO symbol will flash to notify the
driver in event of:
² Low fuel
² High temperature
² Low oil pressure
² Charging system failure

GENERAL INFORMATION
INSTRUMENT CLUSTER
There are two conventional instrument cluster as-
semblies available. The clusters incorporates mag-
netic type gauges and an electronically driven
speedometer and odometer assembly (Fig. 1 and 2).
MAGNETIC GAUGES
All gauges on the AP Body clusters are the mag-
netic type gauges. When the ignition switch is in the
OFF position each gauge, except for the voltmeter
and tachometer will show a reading. However, the
readings are only accurate when the ignition switch
is in the ON position.
TACHOMETER DRIVE MODULE
The tachometer drive module is an electronic mod-
ule used to drive the magnetic tachometer in the
high line cluster. This module is located on top of the instrument
cluster.
ELECTRONIC DIGITAL CLOCK
The electronic digital clock is in the radio. The
clock and radio each use the display panel built into
the radio. A digital readout indicates the time in
hours and minutes whenever the ignition switch is in
the ON or ACC position. When the ignition switch is in the OFF position, or
when the radio frequency is being displayed, time
keeping is accurately maintained. The procedure for setting the clock varies slightly
with each radio. The correct procedure is described
under the individual radio operating instructions re-
fer to the Sound Systems Manual supplied with the
vehicle.
WARNING LAMPS AND INDICATOR LIGHTS
The instrument cluster has warning and indicators
lamps for eight different systems:
² Low oil pressure
² Brake warning
² Seat belt warning
² Malfunction indicator (check engine) lamp
² Air Bag
² High beam indicator
² Right and left turn signals.
² Anti-lock (ABS)
CLUSTER AND GAUGE SERVICE AND TESTING
CAUTION: Disconnect the negative battery cable
before servicing the instrument panel. When power
is required for test purposes, reconnect battery ca-
ble for test only. Disconnect the negative battery
cable after test and before continuing service pro-
cedures.
SENDING UNIT TEST
Check for a defective sending unit or wiring, when
a problem occurs with a cluster gauge. Do this before
disassembling the cluster. (1) Sending units and wiring can be checked by
grounding the connector leads, at the sending unit,
in the vehicle. (2) With the ignition in the ON position, a
grounded input will cause the fuel or temperature
gauge to read at or above maximum.
