U024CLost Communication With Seat Control Module H
- Generic OBD-II code · Network
- How the car detects it
- Seat control module H is Ford's passenger multi-contour seat module (SCMH), the mirror of the driver unit G. It shares the fretting connector problem of TSB 19-2293: on the listed Ford and Lincoln vehicles passenger massage and lumbar act up, sometimes with U024C stored, and the repair replaces the SCMH connector and reroutes the harness. In SSM 53226 the APIM of 2020–2021 F-Super Duty sets U024C when the SCMH was misconfigured during an FDRS update, and Ford wants the SCMH configuration app run after the SCMG one. A related Lincoln case shows the limit of the code: on 2022 Explorer and Aviator intermittent passenger massage came from SCMG/SCMH configuration with no code at all (SSM 50591). So a missing U024C does not clear the module. Passenger massage or lumbar then fail. Driver unit G is U024B; data errors from H are U054D.
