Circuit/System Description (Object Detection System - Park Assist System)

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2013 GMC Savana, 2013 GMC RV Cutaway, 2013 GMC Cutaway, 2013 Chevrolet RV Cutaway, and 2013 Chevrolet Express. However, it is still accessible from the selected car via links, so may be relevant.

When the transmission is placed into REVERSE, 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.
