U056E Invalid Data Received From Image Processing Sensor I

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

The higher letters of the image-sensor series cover the further cameras that newer vehicles add. One growing group looks into the cabin: driver monitoring cameras check whether the driver is watching the road, as Super Cruise does at Cadillac, starting with the 2017 CT6, or Ford's BlueCruise, which uses a module on the steering column of the 2021 Mustang Mach-E and F-150; in the EU such warning systems fall under regulation 2019/2144. Ford's driver monitoring camera module on the 2021–2023 Mustang Mach-E and F-150, the 2022–2023 Expedition and Navigator and the 2023 Corsair reports its own faults as B-codes (B115E, B15E1, B15E2), mostly a blocked view, and Ford's 2024 OBD description treats invalid data from an image processing module as a non-MIL fault (U053B). Whether any maker files such a camera under letter I is not documented, and neither U056E nor its partner U026D appears in public service material. If the receiver keeps rejecting sensor I's data, the dependent assistant becomes unavailable. No MIL.

Likely causes

Sensor I software level not matching the receiving controller
Connector disturbed behind trim, dash or steering column panels
Image processing sensor I internally faulty

Symptoms

  • Hands-free or attention-dependent assistance not offered
