B1A62 on 2021 Cadillac Escalade ESV — Rear Vision Camera
1 vehicles · 1 makes
Most Reported On
B1A62 is an OBD-II diagnostic trouble code meaning “Rear Vision Camera.” A body code owned by the Video Processing Module (VPM) — and, for some symptom bytes, the CSM/Radio — covering faults in the rear vision camera feed. GM enumerates it entirely by symptom byte: B1A62-82 = Rear Vision Camera Alive/Sequence Counter Incorrect, B1A62-86 = Rear Vision Camera Signal Invalid, B1A62-46 = Calibration/Parameter Memory Failure, B1A62-49 = Internal Electronic Failure, B1A62-54 = Missing Calibration, B1A62-55 = Not Configured, B1A62-92 = Performance or Incorrect Operation, B1A62-98 = Component or System Over Temperature. The Escalade issue cites B1A62-86, meaning the VPM received the camera's video/data stream but judged its content invalid rather than absent — which is why the screen goes black with the crossed-out-camera icon while the module itself stays alive on the bus. This code is most commonly reported on 2021 Cadillac Escalade ESV.
