U024BLost Communication With Seat Control Module G
- Generic OBD-II code · Network
- How the car detects it
- Ford assigns seat control module G to the driver's multi-contour seat (SCMG), which runs massage and lumbar adjustment. Two Ford bulletins name U024B. TSB 19-2293, later 19-2390, covers multi-contour seats from the 2013 MKZ to 2019 F-150, Explorer, Expedition and Navigator: massage and lumbar respond only now and then from the switch or touchscreen, sometimes with B1471, U024B or U024C, because terminals fret in the SCMG and SCMH connectors; new pigtails and a rerouted harness fix it. SSM 53226 adds that on 2020–2021 F-Super Duty an SCMG software update by FDRS can misconfigure the module so the SYNC module (APIM) stores U024B; running the SCMG configuration app clears it. Expect driver massage and lumbar to drop out. The passenger unit H is U024C; invalid data from G are U054C.
