Camera, Rear: Description
The Rear View Camera (RVC) (1) is intended to be an auxiliary viewing aid and is not promoted as an obstacle detection or safety device. It does not remove vehicle operator responsibility to recognize and obey official traffic laws or regulations or to take sensible precautions and care to avoid pedestrians, other vehicle traffic or both fixed and moving obstacles through the habitual use of safe and defensive driving techniques.
The RVC is a camera on chip device utilizing Complementary Metal Oxide Semiconductor (CMOS) technology. CMOS technology supports the analog image sensor of the RVC. The RVC also contains a microcontroller and a Local Interface Network (LIN) data bus slave node that communicates over the LIN data bus network with the Body Control Module (BCM), which is a LIN master node and a gateway to the Controller Area Network (CAN) data bus.
The RVC lens (1) is visible near the vehicle center line of the rear horizontal surface of the deck lid (3) in the Center High Mount Stop Lamp (CHMSL) (2). The body of the RVC is concealed within the CHMSL where it is secured with two screws and a mounting bezel to the CHMSL. The RVC is connected to the vehicle electrical system through a dedicated take out and connector of the body wire harness on the underside of the deck lid.
The RVC system uses the touchscreen of the Radio Receiver Module (RRM) near the center of the instrument panel to display the wide angle images captured through the lens of the RVC camera, which faces rearward. The video image includes an active guideline overlay to aid the perception of distance for the operator. These active guidelines change direction with the steering wheel position to indicate the path of the vehicle to aid in parking maneuvers.
The RVC uses hardwired video signal output circuits to provide the RRM video display with compatible National Television System Committee (NTSC) standard composite video M format data, or NTSC-M. These camera output circuits run the entire length of the vehicle and are arranged in tandem as a twisted pair. Portions of these video signal wires are contained within the body wire harness between the RRM and below the instrument panel at the right cowl side inner panel. Data signal protection from corruption and interference is provided by a grounded foil jacket shield which is terminated only at the video display of the RRM.
The RVC cannot be adjusted or repaired. If the RVC is damaged or ineffective, it must be replaced.
