Camera, Rear: Operation

The Rear View Camera (RVC) is powered by an ignition feed received through the backup lamp switch output circuit from the Body Control Module (BCM) so that is only active when the transaxle is shifted into the R  everse position or with the camera delay feature on, the image will remain on while in the N  eutral and D  rive position for 10 seconds, up to 13 km/h (8 mph) or until the user defeats the image by pressing the screen. In addition, the radio receiver monitors messages on the Controller Area Network (CAN) data bus to determine the selected gear and overrides any other display to show the RVC video output, whenever it detects that the transaxle is in R  everse. A momentary blank video display screen immediately following the gearshift transition into the Reverse position is considered normal operation. The camera electronics receive a path to ground at all times.

The camera's output is a video signal compatible to the National Television System Committee (NTSC) standard composite video M format, or NTSC-M. The video signal is delivered to the radio video display unit through the entire vehicle's entire length by camera signal and the camera return circuits arranged as a twisted pair. An additional grounded foil jacket is used to protect the video signal from corruption due to stray radiated signals within the vehicle environment.The ground shield is terminated only at the video display (radio) end, not at the camera. Portions of these video signal wires are contained within the body wire harness and a jumper harness located between the radio and the body harness connector below the instrument panel at the right cowl side inner panel.
