Circuit/System Description
The rear view camera image display module receives a 12-volt signal from the body control module (BCM) indicating that the vehicle is in reverse gear. When this signal is detected the rear view camera image display module will provide a regulated 6-volt power source to the rear view camera. The rear view image will then be displayed on the radio.
If a proper video signal is not detected, the radio will display a SERVICE REQUIRED notification on the radio display.
