For analog rear parking aid cameras 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.
For digital rear parking aid cameras the IPMA and the rear parking aid camera communicate via a LVDS over the coaxial cable. The IPMA is the master module and it sets and stores Diagnostic Trouble Codes (DTCs) for the rear parking aid camera and the communication network.
The messages sent from the BCM or the IPMA to the camera are:
- Camera configuration data

- Guideline on/off request
- Liftgate ajar status
