Circuit/System Description

The frontview 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 frontview camera image display module will provide a regulated 6-volt power source to the frontview camera. The inside rear view mirror (ISRVM) receives a 12-volt signal from the BCM indicating that the vehicle is in reverse gear. The front vision display will then be deployed from the ISRVM. The ISRVM receives video information directly from the frontview camera image display module providing a view to the front of the vehicle. If a problem exists with the front vision display not deploying or if a proper video signal is not detected, the front vision ON/OFF indicator located on the ISRVM will flash.
