Pinpoint Test Q: Internal Control Module Failures

  1. Normal Operation and Fault Conditions 

    Refer to the DTC Fault Trigger Conditions.

    The informational DTC s are the result of the failure mode effects management operating strategy that maintains limited vehicle function in the event of a PCM, harness or component concern.

    Circuit DTC s can be accompanied by the informational DTC s and should be diagnosed first. Informational DTC s without circuit DTC s may or may not indicate the actual concern and should be diagnosed as a symptom.
