The IPMB communicates with the rear parking aid camera and CHMSL camera via a LIN circuit, which is a dedicated single wire communication network. The IPMB is the master module on the LIN, and it sets and stores Diagnostic Trouble Codes (DTCs) for the rear camera, CHMSL camera, and the LIN.
The messages sent from the IPMB to the cameras are:
- Camera configuration data
- Display manual zoom request
- Guideline on/off request
- Trailer connection status (if equipped with factory trailer tow)
- Steering angle (rear camera only)
- Standby enable/disable request
