U054C Invalid Data Received From Seat Control Module G
Ford gives seat control module G a fixed meaning: SCMG is the driver's multi-contour seat module with massage and lumbar functions. Ford's TSB 19-2293 covers vehicles from the 2013 MKZ to the 2019 F-150 and Navigator with intermittent massage and lumbar operation, B1471 and U024B/U024C, caused by fretting terminals at the SCMG and SCMH connectors and fixed with new pigtails and a rerouted harness. On 2020–2021 F-Super Duty a misconfigured SCMG after a software update made the APIM store U024B, cured by the configuration app (SSM 53226). U054C stands for data that arrive but are rejected; Ford documents no case for it. Massage, lumbar or contour settings of the driver seat may then stop or be unavailable from the touchscreen.
Likely causes
Symptoms
- Driver seat massage or lumbar adjustment works only intermittently
- Seat contour settings cannot be operated from the touchscreen
