Module (BCM), Powertrain Control Module (PCM),
Transmission Control Module (TCM), Controller Anti-
Lock Brakes (CAB), and Occupant Restraint Control-
ler (ORC), via the PCI data bus. Upon receipt of
information, the cluster will determine the gauge
position and whether the PCI bus controlled warn-
ings should be turned ON or OFF.

• The ABS is a learned feature by receiving an

ABS message on the bus. Once learned, the ABS
must be unlearned manually by sending a diagnostic
message using a DRB III

t scan tool.

• The AIRBAG light is always supported, but can

be unlearned automatically by using the VIN infor-
mation and the non-receipt of AIRBAG messages.
Receipt of AIRBAG messages will override non-air-
bag VIN information.

• The cluster provides the Auto-Stick (A/S) or

Non Auto-Stick information via the PCI bus. The
TCM will learn A/S or non A/S vehicle configuration
per cluster information on the bus.

• The cluster is set to support vehicles equipped

with a TCM (automatic transmission). In MTX (man-
ual transmission) vehicles, the cluster will turn OFF
gear information upon receipt of vehicle configuration
from the PCM. At initial power-up, you might be able
to potentially see the ATX gear letters. Once the
MTX information is received, the gear letters will be
turned off.

DIAGNOSIS AND TESTING - INSTRUMENT
CLUSTER

As a quick diagnosis, the cluster will perform a

functional check of the odometer display, transmis-
sion range display and warning indicators after the
ignition is switched to RUN/START. If the cluster is
not receiving any PCI bus messages, the cluster will
appear non functional and “no bus” will appear in
the odometer display.

A self-test of the cluster can also be initiated by

pressing and holding the odometer reset button and
switching the ignition from lock to unlock. The clus-
ter will then step through several displays for func-
tional verification. By pressing the trip odometer
reset button while going through the self-test, you
can temporarily freeze the test. Pressing the bottom
again will continue sequence. The cluster will store
bus communication faults with other modules. It will
also store faults for the AIRBAG and ABS lamps.
During the self-diagnostics, the AIRBAG and ABS
lamps are tested.

If the cluster is not functioning properly, refer to

the proper Body Diagnostic Procedures manual.

If the cluster is not receiving PCI bus messages,

refer to the pre-diagnostic test described in Body
Diagnostic Procedures manual.

In order to diagnose the instrument cluster func-

tions, a DRB lll

t scan tool and the proper Body Diag-

nostic Procedures Manual are required.

If the diagnostic procedure determines that a

replacement of an instrument cluster component is
required, refer to Electrical, Instrument Cluster,
Removal, and Installation.

REMOVAL

(1) Disconnect and isolate the battery negative

remote cable.

(2) Remove left end cover.
(3) Using a trim stick (special tool #C-4755) or

equivalent, gently pry up on the power mirror switch.
Disconnect the switch and remove.

(4) Using a trim stick or equivalent, gently pry up

on instrument panel center trim bezel.

(5) Disconnect the HVAC control connector.
Remove the one screw to the inboard passenger

trim bezel on the right of the steering column and
remove by unsnapping clips.

(6) Remove the one screw from the passenger side

trim bezel and remove trim by unsnapping clips.

(7) Remove 4 screws to left lower instrument panel

trim.

(8) Remove the four screws to the cluster bezel.

Using a trim stick or equivalent, gently pry out the
cluster bezel.

(9) If the vehicle is equipped with a Compass

Mini-Trip Computer (CMTC/Traveler), disconnect the
module and then remove the cluster bezel assembly.

(10) For better access and prevention of scratching

the cluster lens, tilt the steering column to its lowest
position and depress the hazard switch.

(11) Remove the cluster attaching screws.
(12) Pull the cluster rearward to disconnect the

26–way self docking connector and then carefully tilt
cluster downward slightly and slide cluster sideways
to remove cluster assembly.

NOTE:

When

replacing

cluster,

the

original

optional bulbs (ABS, rear fog, front fog, traction
control, and security LED) must be transferred to
the new cluster if so equipped.

INSTALLATION

(1) Carefully slide the cluster into its location and

push the cluster forward to connect it to the mating
half of its mating connector on the instrument panel.

(2) Install the four cluster attaching screws.
(3) Position the cluster bezel and if so equipped,

connect the traveler connector, then snap the cluster
bezel into position.

(4) Install the five screws to the cluster bezel.
(5) Install the four screws to the left lower instru-

ment panel trim.

(6) Connect the mirror switch connector and firmly

snap it into place.

(7) Install the one screw to the trim bezel to the

right side of the steering column.

(8) Firmly snap into place and then install one

screw to the passenger side trim bezel.

(9) Connect the HVAC control connectors.
(10) Position the center bezel over the retaining

slots and firmly snap instrument panel center bezel
into place.

(11) Install the left end cover.
(12) Connect the battery negative cable.

INSTRUMENT CLUSTER
MASK/LENS
