LIN Communication

The BCM and the rear parking aid camera communicate via a LIN circuit which is a dedicated single wire communication network. The BCM is the master module on the LIN, and it sets and stores Diagnostic Trouble Codes (DTCs) for the rear parking aid camera and the communication network.

• enable/disable fixed guidelines
• enable/disable active guidelines
• parking aid audible warning status
• parking aid sensor distance to object data
• steering wheel angle data

The reply messages sent from the rear parking aid camera to the BCM are:

• camera status
