Malfunction Indicator Lamp: Testing and Inspection
MIL Circuit Troubleshooting
1. Turn the ignition switch to ON (II).
2. Do the gauge self-diagnostic function See: Instrument Panel, Gauges and Warning Indicators/Instrument Cluster / Carrier/Testing and
Inspection/Initial Inspection and Diagnostic Overview.
Does the MIL indicator flash?
YES -
Go to step 3.
NO -
Substitute a known-good gauge control module, and recheck. If the MIL circuit is OK, replace the original gauge control module See: Instrument Panel,
Gauges and Warning Indicators/Instrument Cluster / Carrier/Service and Repair.
3. Connect the HDS to the DLC See: Testing and Inspection/Initial Inspection and Diagnostic Overview.
4. Check the SCS in the DATA LIST with the HDS.
Is a short indicated?
YES -
Go to step 5.
NO -
Update the PCM if it does not have the latest software See: Testing and Inspection/Programming and Relearning/PCM Update, or substitute a
known-good PCM See: Testing and Inspection/Initial Inspection and Diagnostic Overview, then recheck. If the symptom/indication goes away with a
known-good PCM, replace the original PCM See: Engine Control Module/Service and Repair.
5. Turn the ignition switch to LOCK (0).
6. Disconnect PCM connector A (44P), then disconnect the HDS.
7. Check for continuity between PCM connector terminal A31 and body ground.
Is there continuity?
YES -
Repair a short in the wire between the PCM(A31) and the SRS unit or the DLC.
