²If speedometer is accurate to the calibration points
then look for another possible cause of inaccuracy.
²If speedometer is not accurate to the calibration
points, go to Step (b).
(b) Use a scan tool to calibrate speedometer.

ERRATIC DISPLAY 1. Internal Cluster
Failure.1. (a) Perform Cluster Self Diagnostic Test and check for fault
codes.
²If PRND3L passes the dim test and segment check 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 PRND3L doesn't work go to Step (b).
²If fault code 110 is displayed in the odometer, go to Step (f).
²If fault code 111 is displayed in the odometer display then use a
scan tool to calibrate cluster.
²If fault code 905 is displayed use a scan tool to check electronic
TCM.
(b) Remove cluster from instrument panel and verify that odometer
assembly is properly connected to main pc board. If OK, go to
Step (c). If not OK, reconnect PRND3L assembly to main pc board.
