U026FLost Communication With Image Processing Sensor K
- Generic OBD-II code · Network
- How the car detects it
- Neither U026F nor the meaning of letter K appears in published manufacturer material. Some image sources are optional or arrive with towing equipment, and that matters before diagnosing a silent camera. GM ties the turn signal activated camera view of 2025–2026 Escalade, Tahoe, Suburban, Yukon, Silverado EV and Sierra EV to option code TRG, the trailer camera provisions. Without that option the feature does not exist at all; with it, a view that failed to appear without a trailer attached was put right by radio software (PIT6366, PIT6366A). So confirm first that the vehicle is built and configured for an extra camera. A genuine loss of sensor K removes only its view or assistant; there is no MIL and no effect on emissions.
