MOVEMENT1. Internal cluster failure. 1. (a) Perform cluster self diagnostic test and check for
fault codes.
²If speedometer 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
(b).
²If fault code 110 is displayed in the odometer, go to
Step (b).
²If fault code 111 is displayed in the odometer then go
to Step (f).
²If fault codes 905, 920, or 940 are displayed in the
odometer display 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, complete 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 speedometer failure.

Message.2. (a) Check the Body Control Module (BCM) using a
scan tool. If OK, go to Step (b). If not OK, refer to the
BCM section of the service manual to repair the BCM.
(b) Check the Powertrain Control Module (PCM) using
a scan tool. If OK, go to Step (c). If not OK, refer to the
PCM section of the service manual to repair the PCM.
(c) Check the speed signal input into the PCM. The
speed signal originates from one of the following
sources:
²A distance sensor for vehicles with 3 speed automatic
transmission. Check continuity from distance sensor to
PCM. If OK, replace distance sensor. If not OK, repair
wiring.
²The Electronic Transmission Control Module (TCM)
for vehicles with the 4 speed electronic transmissions.
Check continuity from TCM to PCM. If OK, use a scan
tool to check TCM. Refer to the electronic TCM section
of the service manual to repair the TCM. If not OK,
repair wiring.
