Circuit/System Description

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 Night Vision Control Module performs fault detection on itself and the camera attached to it. The night vision control module sends a processed image output directly to the instrument cluster via a dedicated LVDS video cable. The Instrument Cluster monitors the video signal for faults.
