Component Description: BCM
WARNING: This page is about a different car, the 2023 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
The BCM is the master module in control of the power door lock system. It is responsible for locking/unlocking the doors. The BCM receives inputs for the door lock control switches, keys and RKE commands over the CAN and LIN-based circuits.
When the BCM is replaced, the parameter reset and PMI procedures must be carried out and at least 2 keys programmed to it.
