Diagnostic Aids

A poor video image can be caused by ice, snow, and mud buildup on the lens of the rearview camera. Also, extreme lighting conditions can affect performance, such as operating in the dark or with bright sunlight shining on the camera. Extreme high or low temperatures can also affect the image quality. An open in the shield of the video signal circuit can also cause a distorted screen.

An open in the backup lamp control circuit, defective backup lamps, or incorrect/aftermarket backup lamps can cause erratic circuit behavior such as unwanted voltage on circuit when vehicle is no longer in REVERSE. The rear vision image display remaining active after the vehicle is shifted out of REVERSE can also be an indication of backup lamp control circuit issues.
