CORRECTION
1. (a) Perform Cluster Self Diagnostic Test and check
for fault codes.
• If 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.
• If the pointer doesn't move during test, go to Step
(b).
• If fault code 110 is displayed in the odometer, go to
Step (b).
• If fault code 111 is displayed in the odometer then go
to Step (f).
• If fault codes 920 or 940 are displayed refer to the
fault code chart to identify which module is causing the
fault and repair module.
(b) Replace main cluster pc board. Go to Step (c).
(c) Connect cluster into instrument panel wiring
harness. Place it back into the proper position in the
instrument panel. Put in the top two mounting screws to
hold the cluster in place. DO NOT COMPLETELY
INSTALL CLUSTER TO INSTRUMENT PANEL UNTIL
UNIT IS CALIBRATED AND TESTED. Go to Step (d).
(d) use a scan tool to calibrate cluster and perform Self
Diagnostic Test. If OK, continue installation. If not OK,
go to Step (e).
(e) Replace subdial assembly and use a scan tool to
calibrate cluster. If not OK, look at another possible
cause for the temperature gauge failure.
(f) Use a scan tool to calibrate temperature gauge and
perform Self Diagnostic Test. If OK, stop. If not OK, go
to Step (b).
2. (a) Check BCM fault codes using a scan tool. If
there are not faults, go to Step (b). If there are faults,
refer to the BCM section of the manual to properly
diagnose and repair.
(b) Check PCM fault codes using a scan tool. If there
are no faults, go to Step (c). If there are faults, refer to
the PCM section of the manual to properly diagnose
and repair.
(c) Refer to the coolant sensor section of the service
manual for the coolant sensor test procedure. Repair
sensor as needed.
