Circuit/System Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 GMC Sierra 3500 HD, 2015 GMC Sierra 2500 HD, 2015 GMC Sierra 1500, 2015 Chevrolet Silverado 3500 HD, and 2015 Chevrolet Silverado 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

When the transmission is placed into R, a 12 V signal is sent to the rearview camera indicating that camera operation is requested. Ignition voltage and ground are supplied to the rearview camera. The rearview camera sends video information to the radio through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.
