NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 Do not turn the ignition switch to LOCK (0) while updating the PCM. If you turn the ignition switch to

1. Turn the ignition switch to ON (II).
2. Do the gauge self-diagnostic function (see page22-241).

module (tach), and recheck. If the MIL circuit is OK,
replace the original gauge control module (tach)
(see page 22-277).
3. Connect the HDS to the DLC (see page 11-3).
4. Check the SCS in the DATA LIST with the HDS.
Go to step 5.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
5. Turn the ignition switch to LOCK (0).
6. Disconnect ECM/PCM connector A (44P), then disconnect the HDS. 7. Check for continuity between ECM/PCM connector
terminal A31 and body ground.
Repair short in the wire between the ECM/
PCM (A31) and the SRS unit, the DLC.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
