Rear Vision Camera System Operation

The rear vision camera system consists of a video camera/module located at the rear of the vehicle and the radio.

The rear vision camera receives ignition voltage and a constant ground to power the camera. Video signal + and video signal - circuits carry the video image from the rear vision camera to the infotainment display. Additionally, the video signal circuits are shielded to prevent any interference which may lead to a loss of video signal resolution and a degraded video image. The shield is provided a ground path by the rear vision camera. When the transmission is placed into REVERSE, the Radio displays the video image.

The following conditions may cause a degraded rear vision camera image:

If a malfunction is detected in the system, Service Rear Vision Camera may be displayed on the infotainment display as an indicator to the customer that a problem exists that requires service.
