A Diagnostic Starting Point - Body Control System
Begin system diagnosis with the Diagnostic System Check -
Body Control Module. The Diagnostic System Check will provide the information on how to retrieve DTCs from the
body control module (BCM) and their status. The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
