MIL Circuit Troubleshooting

1. Turn the ignition switch to ON (II).
2. Do the gauge self-diagnostic function (see page
22-312).
Does the MIL indicator f lash?
YES − Go to step 3.
−
NO Substitute a known-good gauge control
module, and recheck. If the symptom/indication
goes away with a known-good gauge control
module, replace the original gauge control module
(see page 22-332).
3. Connect the HDS to the DLC (see page 11-3).
4. Check the SCS in the DATA LIST with the HDS.
Is a short indicated?
−
YES Go to step 5.
NO − Update the ECM/PCM if it does not have the
latest software (see page 11-231), 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 11-232).
5. Turn the ignition switch to LOCK (0).
6. Disconnect ECM/PCM connector A (49P), then
disconnect the HDS.
7. Check for continuity between ECM/PCM connector
terminal A32 and body ground.

SCS (ORN)
Terminal side of female terminals
Is there continuity?
YES − Repair short in the wire between the ECM/
PCM (A32) and the DLC.
NO − Update the ECM/PCM if it does not have the
latest software (see page 11-231), 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 11-232).
