ACM Message Not Received By MIC

When Monitored: With the ignition on.

Set Condition: No ACM messages received for 6 seconds.

Possible causes are:

Turn ignition on. Using the DRBIII(R), attempt to I/D or communicate with the ACM. Is there a response from the ACM Module? If yes, go to next step. If no, go to NO RESPONSE FROM AIRBAG CONTROL MODULE in COMMUNICATION under SYMPTOM TESTS. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
Using the DRBIII(R), erase the DTC from Instrument Cluster. Cycle the ignition and wait approximately 1 minute. Using the DRBIII(R), read DTCs. Did this DTC reset? If yes, replace the Instrument Cluster. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS. If no, the condition is not present at this time. Monitor DRBIII(R) parameters while wiggling the related wire harness. Refer to any Technical Service Bulletins (TSB) that may apply. Visually inspect the related wiring harness and connector terminals. Perform BODY VERIFICATION TEST VER 1 under VERIFICATION TESTS.
