B1A62 on Cadillac
Rear Vision Camera
B1A62 on Cadillac vehicles indicates rear vision camera. Au7o has documented this code across 1 Cadillac model — most commonly on Escalade ESV. 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.
Common Causes of B1A62
- •Video Processing Module (VPM) software anomaly — the dominant cause per GM 23-NA-007 and PIT6369B, corrected by module reset or reprogramming rather than parts
- •Rear vision camera internal electronic failure (symptom 49)
- •Lost, missing or corrupted camera calibration / configuration data in the VPM (symptoms 46, 54, 55)
- •Degraded coaxial/LVDS link between the rear camera and the VPM — connector corrosion, chafed or pinched coax, poor Fakra connector seating
- •Camera or module over-temperature (symptom 98)

- Black Radio Screen With U023C and B1A62-86 Needs VPM Recovery2021
GM 21-NA-209 covers a bounded 2021 Escalade ESV condition with RPO UXP: a black radio screen showing a triangle and camera-slash symbol with current or recent U023C and B1A62-86. It does not establish general OLED hardware, flicker or infotainment-module failure.
