Diagnostic Aids

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The following conditions could cause component performance issues: Surround Vision Camera

Ambient Light Intensity - High/Low
Camera Blocked - Debris/Ice/Mud/Snow
Temperature - High/Low

An open in the shield of the video signal circuit can cause a distorted screen.

If the Video Processing Module cannot calibrate all cameras, the rear vision image may be displayed without projected path lines.

If the Video Processing Module loses communication with the Power Steering Control Module, the rear vision image may also be displayed without projected path lines.

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.
