Component Description: BCM

The BCM is the master module in control of the power door lock system. It is responsible for locking/unlocking the doors and releasing the liftgate latch. The BCM receives direct input from the door lock control switches. It receives passive entry and RKE commands from the RFA module over MS-CAN.

If the BCM is replaced, at least two keys must be programmed to it and a parameter reset performed with the RFA module and the PCM to disable the PATS.

The BCM requires PMI when replaced.
