²If temperature gauge pointer moves to calibration
points during test and fault codes 110 or 111 don't
appear in the odometer display then failure is not in the
cluster. Look for another possible cause of failure.
²If the pointer doesn't move during test, go to Step

DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
GS vehicle instrument clusters are equipped with a
self diagnostic test feature to help identify electronic
problems. Prior to any test, perform Self Diagnostic
Test. The self diagnostic system monitors the CCD
bus messages. If an electronic problem occurs, a
Diagnostic Trouble Code (DTC) will be displayed in
the odometer window of the cluster.
The following CCD bus messages are continuously
monitored by the diagnostic system:
²Body Control Module
²Powertrain Control Module
HEADLAMP SWITCH
Using a Digital Multimeter, equipped with a diode
test to perform the Headlamp Switch Test below (Fig.
3).
Switch position possibilities are open (no continu-
ity), continuity, resistance value in ohms, or diode
test. Use the values in the third column to determine
meter setting. If Headlamp Switch is not within spec-
ifications replace as necessary.

DESCRIPTION AND OPERATION (Continued)

SELF DIAGNOSTIC TEST
With the ignition switch in the OFF position,
depress the TRIP and RESET buttons. While holding
the TRIP and RESET button turn the ignition switch
ON. Continue to hold the TRIP and RESET buttons
until the word CODE appears in the odometer win-
dows (about five seconds). If a problem exists, the
system will display diagnostic trouble codes. If no
problem exists the code 999 (End Test) will momen-
tarily appear.
DIM TEST
When CHEC-0 is displayed in the odometer win-
dow, the cluster's vacuum fluorescent (VF) displays
will dim down. If the VF display brightness does not
change, a problem exists in the cluster.

DIAGNOSIS AND TESTING (Continued)

CALIBRATION TEST
When CHEC-1 is displayed in the odometer win-
dow, each of the cluster's gauge pointers will move
sequentially through each calibration point. The Cal-
ibration Table contains the proper calibration points
for each gauge. If the gauge pointers are not cali-
brated, a problem exists in the cluster. If any gauge
is out of calibration it will have to be calibrated using
a scan tool (DRB III). Refer to the proper Body Diag-
nostic Procedure Manual for calibration procedures.
ODOMETER SEGMENT TEST
When CHEC-2 is displayed in the odometer win-
dow, each digit of the odometer will illuminate
sequentially. If a segment in the odometer does not
illuminate normally, a problem exists in the display.
