U050A code meaning
Invalid Data Received From Seat Control Module B
What U050A means
For seat control module B there is a fairly clear manufacturer assignment. Ford calls the front passenger seat unit SCMB, for example in the 2024–2026 Lincoln Nautilus, where it held B120A:2A with an inoperative heated seat (SSM 54647), while the driver side is the DSM. Ford's letters follow the generic slots: after a seat module G/H update, F-Super Duty APIMs stored U024B and U024C, the generic codes for seat modules G and H (SSM 53226). GM's Saab 9-5 uses the B partner slot U0209 for the front seat heating module. U050A therefore points to the front passenger seat electronics on many cars; it is stored when that module's data is received but rejected. Missing data is U0209.

What each part of U050A means

What to do next
- Note U050A 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.
