Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
When the engine is running, and the transmission is placed into R, a vehicle in reverse motion message is sent via serial data to the video processing control module indicating that camera operation is requested. When the engine is running, and the transmission is placed into D, a vehicle in forward motion message is sent via serial data to the video processing control module. The cameras send video information to the video processing control module 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. The signals from the cameras are combined and sent to the radio or human machine interface module.
