U050C code meaning
Invalid Data Received From Door Control Module H
What U050C means
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.

Symptoms of U050C
- Power sliding door moving only partly or not at all
- Door ajar or door fault message
Common causes of U050C
- PossiblePower sliding door latch or adjustment fault feeding wrong states (Ford Transit)

What each part of U050C means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0C | The exact fault in that area. |
What to do next
- Note U050C and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
