Body Control Module (BCM)

The BCM-B determines the vehicle ignition mode based on the ignition switch input. The BCM-B communicates the ignition mode to the other modules over the MS-CAN and the HS-CAN. The BCM-B monitors the ignition switch input and the ignition mode outputs, if a fault is detected in the ignition system DTCs are set by the BCM-B.
