Lost Communication With Camera Module Rear
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The vehicle bus reports loss of communication with the rear camera module. The reverse-camera image, dynamic guide lines and any cross-traffic alert from this camera are unavailable.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
