WARNING: This page is about a different car, the 2008 GMC Sierra, 2008 GMC Cab & Chassis Sierra, 2008 Chevrolet Silverado, and 2008 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The rear vision system can help a driver determine how close an object is to the rear bumper within a predefined rearward field of view. The system is composed of a video camera located on the rear liftgate, rearview camera image display module, electrical harness and the image display located on the radio.

The rearview camera image display module receives an active high (12-volt) signal from the body control module (BCM) when the vehicle is shifted into reverse. With the transmission is in the reverse, the rearview camera image display module will supply the camera with a regulated 6-volt power source. The rearview camera image display module also serves to process the video information from the camera and deliver it to the radio. The image from the rearview camera will only be displayed in the radio when the vehicle is in reverse.

The radio can display the following rear vision error messages:

Rear Vision Camera System Unavailable-This message may display when the system is not receiving information it requires from other vehicle systems.
Service Rear Vision Camera System-This message may display when the system is not receiving video from the camera.
