The decklid must remain closed for correct operation of the video camera system.
The video camera system has 5 user-selectable features:
- Fixed guidelines - assists the driver with aligning the vehicle with an object.
- Active guidelines - displays the intended path of the vehicle based upon steering wheel input.
- Visual park aid alert - assists the driver to visually see the object causing the parking aid system to sound.
- Manual zoom - assists the driver with connecting or towing a trailer allowing the driver to manually zoom closer to an object behind the vehicle.
- Video camera delay - allows the driver to see the image behind the vehicle after the vehicle is shifted out of REVERSE. The image will not be displayed if the vehicle is shifted into PARK.
On vehicles equipped with the 203 mm (8 in) touchscreen, the camera commands controlled by the driver are generated at the FDIM which is hardwired to the APIM . On vehicles not equipped with a 203 mm (8 in) touchscreen, the camera commands controlled by the driver are generated at the FCDIM . The camera commands are then sent to the BCM . The BCM sends the command to the video camera via the LIN circuit. On vehicles equipped with a 203 mm (8 in) touchscreen, the video camera outputs the video signal to the APIM , which is directly connected to the FDIM , which displays the image. On vehicles not equipped with a 203 mm (8 in) touchscreen, the video camera outputs the video signal to the FCDIM , which displays the image.
The BCM and the video camera communicate via a LIN circuit which is a dedicated single wire communication network.
The messages sent from the BCM to the video camera are:
- Transmission in reverse
- Decklid ajar status
- Camera configuration data
- Display manual zoom request
- Parking aid audible warning status
- Parking aid sensor distance to object data
The messages sent from the video camera to the BCM are:
- Camera status
- Display zoom status
- Camera part number data
- Visual park aid alert status
- Fixed guideline status
