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

Passenger seat module configuration not matching the vehicle
Fretting corrosion at the passenger seat module connector
Passenger multi-contour seat module internally faulty

Symptoms

  • Passenger seat massage starts and stops on its own
  • Passenger lumbar or contour adjustment does not respond
