Rear Vision Camera System Operation - H3

The components used in the rear vision camera system are the camera located at the rear of the vehicle, the rearview image display module, and the inside rearview mirror, which houses the LCD display.

When the vehicle is placed in REVERSE, the body control module (BCM) sends a 12 volt signal to the rearview image display module. This signal indicates that rear vision camera operation is required. Upon receipt of this signal, the rearview image display module will supply ignition voltage to the rear view camera. The rear vision camera transmits the video signal to the navigation radio through discrete + and - signal circuits. A metallic foil encases the video signal circuits and is tied to a shield ground circuit. This shield is designed to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

If desired, the rear vision camera may be manually disabled. Refer to the navigation system owners manual for instructions on manually disabling and enabling the rear vision camera system. The following conditions may cause a degraded rear vision camera image:
