U054D Invalid Data Received From Seat Control Module H
Seat control module H is Ford's multi-contour module for the passenger seat (SCMH), the counterpart of SCMG. On 2022 Explorer and Aviator an intermittent passenger massage function without any stored code was traced to the configuration of both modules; first no fix was available, later reprogramming plus the configuration apps solved it (SSM 50591, 51927). The F-Super Duty case SSM 53226 shows where bad seat data is noticed: the APIM, which operates the seats from the SYNC screen, stored U024C. U054D is the code for an SCMH that still transmits but sends content failing validation, for instance after a wrong configuration or with fretting contacts at its plug. Passenger massage or lumbar adjustment then works only now and then.
Likely causes
Symptoms
- Passenger seat massage starts and stops on its own
- Passenger lumbar or contour adjustment does not respond
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
