U026ALost Communication With Image Processing Sensor F
- Generic OBD-II code · Network
- How the car detects it
- At GM letter F belongs to the frontview camera module (K109, later B174W) on the windshield, which serves forward collision alert, IntelliBeam and the lane departure and lane keeping functions. On 2016–2017 Chevrolet, GMC and Cadillac models such as Malibu, Silverado, Tahoe and Escalade, early camera software made the cluster or body module store a history U026A or U023A while the Service Front Camera message came and went; later software could hang the camera at power-down, keep it warm and drain the battery within 30 days. GM prescribes reprogramming and no new part (16-NA-389, PIT5482A). On 2022–2023 XT5, XT6, Equinox, Acadia and Terrain, camera pins that are pushed back or absent can set U026A, and then the camera is replaced (PIT6046). Lane and collision warnings drop out; no MIL.
