Body Control Module (BCM)

The BCM is the master module in control of the power door lock system. It is responsible for locking/unlocking the doors, releasing the liftgate glass latch and releasing the liftgate latch. The BCM receives inputs from the door lock control switches, the keyless entry keypad, the liftgate glass release switch, the liftgate release switch and RKE commands from the Radio Transceiver Module (RTM).

The BCM requires PMI, the parameter reset procedure, and at least 2 keys programmed to it, when replaced.
