Ford uses seat control module J (SCMJ), also called power fold seat module (PFSM), for the electrically folding third row. On 2025 Expedition and Navigator a software fault made the seats ignore the 3L, Both and 3R buttons; a relearn with the engine running and the liftgate open, holding Both for one minute and five seconds more after the seats stop, restores them until an update arrives (SSM 53681). SSM 54613 reports uneven upright seats after an obstruction reset on 2025–2026 models, cured by a second reset. A 2024 scan-tool release also lists SCM-J for several Ford models. No bulletin cites U024D. The code stands for an SCMJ that has gone silent on the bus, so supply, ground and the harness that flexes with the seat come before software. Third-row folding stops. Data errors from J are U054E.

Likely causes

Harness or connector damaged where it flexes with the folding seat
Fold seat module without power or ground (fuse)
Module software locked up, needs relearn or update
Fold seat module internally faulty

Symptoms

  • Third-row power fold buttons without effect
  • Seats stop half-way or stand misaligned
