U023BLost Communication With Image Processing Module B

  • Generic OBD-II code · Network
How the car detects it
U023B points to image processing module B. GM uses it on its newer Super Cruise vehicles: PI PIC6607 (2026 Cadillac LYRIQ and VISTIQ) lists U023B SYM00 as a history entry next to U3000, U1624, U0140 and U053C and states that these do not explain a Super Cruise unavailable message, so the image processing module must not be replaced for them; the real fault is found with GM's Super Cruise diagnosis. Ford names its 360 degree camera computer IPMB, for example on the 2020-2021 Explorer, Aviator and Corsair (SSM 49980, blue screen, reflash and camera alignment), so on Ford a U023B concerns that unit. Only a current code with a matching symptom needs wiring and supply checks. U053C covers invalid data from B; no MIL.
