Parking Aid Camera
The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN (local interconnect network) bus connection from the RJB which is not used at the moment but installed for a later enhancement of the parking aid camera.
A shielded co-axial cable connection between the camera and the Touch Screen Display (TSD) is used for the video image transmission.
The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected signal on the medium speed CAN bus message to the entertainment system control module. This message is transferred on the MOST to the TSD which displays the parking aid camera video input from the camera in preference to the parking aid alert screen.
If the driver does not require the camera image in the TSD, a single touch on the screen will revert the display to the parking aid alert screen. The camera view can be reselected by pressing the 'Rear Camera' softkey on the TSD.
When reverse gear is deselected, the camera image remains on the TSD for 10 seconds after the transmission has been put into drive 'D'. This is to prevent the TSD switching between screens if the vehicle is being maneuvered into a parking space. If the vehicle forward speed exceeds 16 km/h (10 mph) within the 10 second period, the camera image is removed from the TSD.
If the TSD display is switched off, the camera image will be automatically displayed when reverse gear is selected. When reverse gear is deselected and the 10 second period has expired, the TSD will revert back to its switched off state.
The parking aid camera receives an ignition power mode 6 power supply from the RJB. It also has a LIN bus connection with the RJB, which is used as a gateway.
A shielded co-axial cable connection between the camera and the TSD is used for the video image transmission.
The camera receives power at all times when the ignition is in power mode 6. When reverse gear is selected, the RJB transmits a reverse selected message on the medium speed CAN bus. The information and entertainment module transfers the message on the MOST ring to the TSD, which displays the video input from the parking aid camera in preference to the parking aid alert screen.
The display from the camera incorporates graphic overlays, indicating vehicle direction, width and proximity to surrounding objects.

A single touch on the screen will revert the display to the parking aid alert screen. The camera view can be reselected by pressing the Rear Camera soft key on the TSD.
When reverse gear is deselected, the camera image remains on the TSD for 2 seconds after the transmission has been put into D (drive). If the vehicle forward speed in D exceeds 16 km/h (10 mph) the camera image is removed from the TSD.
If the TSD is switched off, the camera image will be automatically displayed when reverse gear is selected. When reverse gear is deselected, after 10 seconds the TSD will revert back to its switched off state.
