Door control module H, the last door slot, is used by Ford in two different ways. In the Mach-E, Aviator and Nautilus it is the fourth electronic latch module, DCMH, updated together with DCME–DCMG. In the 2020–2022 Transit it controls the power sliding door: TSB 22-2305 describes a sliding door that partly moves or fails to open or close, with U201A possibly stored in DCMH, fixed by a new latch, conical washers and door adjustment. So on a van, U050C most likely concerns the sliding door, on a passenger car a latch. The code is set when a receiver rejects DCMH's frames as invalid; U020B stands for lost contact. No bulletin shows U050C itself.

Likely causes

Power sliding door latch or adjustment fault feeding wrong states (Ford Transit)
Latch module software (Ford DCMH)
Worn wiring in the sliding door track or hinge

Symptoms

  • Power sliding door moving only partly or not at all
  • Door ajar or door fault message
