U050AInvalid Data Received From Seat Control Module B
- Generic OBD-II code · Network
- How the car detects it
- 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.
