U056BInvalid Data Received From Image Processing Sensor F
- Generic OBD-II code · Network
- How the car detects it
- At GM, the partner of U056B – U026A – belongs to the front camera module B174W. A 2023 GM note for 2022–2023 Cadillac XT5 and XT6, Chevrolet Equinox and GMC Acadia and Terrain blames U026A plus the front-camera warning on terminals in that camera that were pushed back or absent, which then has to be replaced. On 2016 Escalade, Malibu, Silverado, Suburban, Tahoe, Sierra and Yukon, U026A could appear in the cluster or body module because of camera software, and GM advised against replacing parts. Sensor F is thus a forward camera on these GM platforms, whereas the 2020 CT4 and CT5 file their windshield camera under letter A. U056B itself is in no public bulletin; lane and collision functions are likely off while it is set. No MIL.
