GAUGES
It is not necessary to remove instrument clus-
ter assembly from vehicle for gauge replace-
ment. When removing gauge assemblies from cluster,
gauge must be pulled straight out, not twisted, or
damage to gauge pin may result.
MULTIPLE GAUGE MALFUNCTION
If the fuel, voltage and tachometer gauges appear
to be malfunctioning, remove the cluster assembly.
Check for good pin contact between the wire harness
and printed circuit board. If there is good contact,
check for ignition voltage at ignition cavity C of the
black connector. If there is ignition voltage, check for
continuity between the wire harness ground cavity H
of the black connector and ground. If there is conti-
nuity, replace printed circuit board. If the temperature, oil pressure and speedometer
gauges appear to be malfunctioning remove the clus-
ter assembly. Check for a good contact between the
wire harness and the printed circuit board. If there is
good contact, check for ignition voltage at cavity J of
the red connector. If there is voltage, check for con- tinuity at cavity H of the black connector. If there is
continuity, replace the printed circuit board.
If the temperature, fuel, voltage and speedometer
gauges appear to be malfunctioning, remove the clus-
ter assembly. Check for good pin contact between the
wire harness and the printed circuit board. If there is
good contact, check ignition voltage at cavity J of the
red connector. If there is voltage, check for continuity
at cavity H of the black connector. If there is conti-

cluster (Fig. 37 and 38). Successful completion of the SELF DIAGNOSTIC
TEST indicates that the problem is in the connectors
or sensors outside of the module. Refer to Fig. 39 for
terminal listing.

GAUGES
It is not necessary to remove instrument cluster
from vehicle for gauge replacement. When removing
gauge assemblies from cluster, gauge must be pulled
straight out, not twisted, or damage to gauge pins
may result.
MULTIPLE GAUGE MALFUNCTION
If all the instrument cluster gauges appear to be
malfunctioning, remove the cluster assembly.
² Check for good pin contact
² Check for ignition voltage between the IGN cavity
D and ground.
² If there is ignition voltage
² Check for continuity between the wire harness
ground cavity G and ground.
² If there is continuity, replace the print circuit
board (Fig. 16).
GAUGE INOPERATIVE (FIG. 17 THROUGH 20)
(1) Remove gauge in question.

ELECTRONIC CLUSTER
SELF DIAGNOSTIC SYSTEM
The electronic clusters have an internal diagnostics
routing to isolate problems within the cluster or CCD
Bus. Using the cluster Self-Diagnostic Test will deter-
mine whether the problem is within the cluster or
outside of cluster (Fig. 29 and 30). Successful completion of the Self Diagnostic Test
indicates that the problem is in the CCD Bus, inter-
facing modules, connectors, or sensors outside of the
cluster. Refer to Fig. 31 for terminal listing.
CONDITION: CLUSTER DISPLAYS DO NOT ILLUMINATE AFTER VEHICLE IS STARTED
PROCEDURE
(1) Check fuses and verify battery and ignition
voltage at cluster connector. (2) Check ground from cluster connector to instru-
ment panel ground stud.
CONDITION: CLUSTER ASTERISK (*) FLASHES, CLUSTER DISPLAYS NOTINDICATING CORRECT DATA.
PROCEDURE
CCD bus problem. Use the Body Chassis Diagnos-
tic Manual to diagnose CCD Bus.
CONDITION: SPEEDOMETER AND ODOMETER ARE INOPERATIVE OR OPERATESINTERMITTENTLY
PROCEDURE
(1) If speedometer reads 0, or odometer is blank,
and cluster asterisk is flashing, use the Body Chassis
Diagnostic Manual to diagnose CCD Bus problem. (2) If cluster asterisk is not flashing, check for de-
fective vehicle speed sensor or speed sensor wiring.
CONDITION: OIL GAUGE, FUEL GAUGE, TEMPERATURE GAUGE, OR VOLTAGE GAUGEINOPERATIVE
PROCEDURE
If any gauge gives no indication and cluster aster-
isk is flashing, use the Body Chassis Manual to diag-
nose CCD Bus problem. If cluster asterisk is not flashing:
(1) Check for defective sending unit or wiring. (a) Sending units and wiring can be checked by
grounding the connector leads, at the sending unit,
in the vehicle. (b) With the ignition in the ON position, a
grounded input will cause the oil, fuel, or temper-
ature gauge to read maximum. (2) If the problem is with the oil, temperature, or
fuel gauge, check the body controller. If the problem
is with the voltage gauge, check the powertrain con-
trol module operation.
CONDITION: CLUSTER DISPLAY DOES NOT DIM WHEN HEADLAMP SWITCH ISACTIVATED AND RHEOSTAT ROTATED
PROCEDURE
If the cluster asterisk is flashing, Refer to the Body
Chassis Diagnostic Manual to diagnose the CCD Bus. If the cluster asterisk is not flashing:
(1) Check fuses in headlamp circuit.
(2) Check for loose connections or defective wiring
for headlamp switch to body controller. (3) Check for defective headlamp switch. The elec-
tronic instrument cluster receives the display inten-
sity status from the body controller via the CCD Bus.
CONDITION: SEAT BELT WARNING LAMP DOES NOT ILLUMINATE
PROCEDURE
Turn on ignition. Lamp should illuminate for six
seconds. If not: (1) Check for burned out lamp and retest.
(2) Replace cluster.
CONDITION: LOW WASHER, DOOR/DECK, OR MALFUNCTION INDICATOR (CHECK ENGINE)LAMP, DO NOT ILLUMINATE
PROCEDURE
(1) Perform cluster self-diagnostics to determine if
lamp will illuminate. If lamp does not, check for
burned out lamp, replace and retest. (2) If cluster asterisk is flashing, Refer to the Body
Chassis Diagnostic Manual to diagnose CCD Bus. (3) If cluster asterisk is not flashing:(a) For low washer fluid or door/deck, check in-
puts to body controller. (b) For malfunction indicator (check engine),
check powertrain control module operation.
CONDITION: ODOMETER DISPLAY IS BLANK. THE ODOMETER VALUE IS NO LONGERRETAINED IN THIS ELECTRONIC CLUSTER.THIS TAKES PLACE IN THE BODYCONTROLLER
PROCEDURE
(1) If cluster asterisk is flashing, Refer to the Body
Chassis Diagnostic Manual to diagnose CCD Bus. (2) If cluster asterisk is not flashing, perform clus-
ter self-diagnostics. If code 921 appears in the odom-
eter display, replace body controller for odometer
failure.
