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.

Likely causes

Seat module configuration lost or wrong after programming (Ford SCMB)
Harness under the passenger seat pinched or connector loose
Seat control module B internally faulty

Symptoms

  • Passenger seat heating or adjustment not working
  • Seat settings missing in the center display
