B1A62 on Cadillac by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Black radio screen
- Triangle and camera-slash symbol on the display
How to Fix
Confirm the exact display pattern, RPO and DTCs. The GM procedure removes VPM fuse F28 for one minute, reinstalls it and has the dealer reprogram the K157 Video Processing Module. Do not replace the OLED display from this card.

Frequently asked questions
What does B1A62 mean on a Cadillac?
B1A62 stands for "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. On Cadillac it is documented across 1 model: Escalade ESV.
What are the most common causes of B1A62?
The most common causes of B1A62 are: 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). The specific cause varies by vehicle.
