BCM (Vehicles Without 180 Degree View Camera)
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
The BCM serves as a gateway between the rear parking aid camera and other modules on the HS-CAN1. It communicates with the rear parking aid camera via the LIN and stores Diagnostic Trouble Codes (DTCs) for the camera and the LIN in the event of a concern.
The BCM requires PMI when replaced. Refer to: Module Configuration - System Operation and Component Description .
