U024D code meaning
Lost Communication With Seat Control Module J
What U024D means
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.
U024D at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.2 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U024D
- Third-row power fold buttons without effect
- Seats stop half-way or stand misaligned
Common causes of U024D
- Most likelyHarness or connector damaged where it flexes with the folding seat
- PossibleFold seat module without power or ground (fuse)
- PossibleModule software locked up, needs relearn or update
- Less likelyFold seat module internally faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U024D means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4D | The exact fault in that area. |
What to do next
- Note U024D and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U024D
What does U024D mean?
U024D means "Lost Communication With Seat Control Module J". Ford uses seat control module J (SCMJ), also called power fold seat module (PFSM), for the electrically folding third row. It is a generic code, so it means the same on every make.
Is it safe to drive with U024D?
U024D does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U024D fail an emissions test?
U024D is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U024D to fix?
Difficulty: medium. A typical repair takes 0.2 to 2.5 hours of work. This is a job for a workshop.
Will U024D clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
