Component Description: BCM
WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The BCM settings and configuration have no influence over the video signal from the rear parking aid camera. The camera provides a video signal any time it receives voltage and ground.
The BCM serves as a gateway module between the rear parking aid camera and other modules on the HS-CAN and MS-CAN. 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.
