INSTRUMENT PANEL AND SYSTEMS
CORRECTION
1. (a) Perform Cluster Self Diagnostic Test and check
for fault codes.
•If fuel 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 code 920 is displayed in the odometer 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 fuel gauge failure.
(f) Use a scan tool to calibrate fuel gauge and perform
Self Diagnostic Test. If OK, stop. If not OK, go to Step
(b).
2. (a) Check the BCM using a scan tool. If OK, go to
Step (b). If not OK, refer to the BCM section of the
manual to properly diagnose and repair.
(b) Refer to the Fuel section of the service manual for
the fuel level sending unit test procedure. Test unit and
repair as instructed.
