U054E code meaning
Invalid Data Received From Seat Control Module J
What U054E means
Ford calls the module that folds the third-row seats electrically both PFSM and seat control module J (SCMJ). On 2025–2026 Expedition and Navigator its software left the seats unwilling to fold when 3L, Both or 3R was pressed, restored by a relearn in which Both is held for one minute and then five seconds more (SSM 53681), and caused misaligned upright seats after an obstruction reset (SSM 54613). Since the module halts motion on an obstruction and reports seat position, wrong data from it can confuse switch and liftgate-area logic. U054E means its frames arrive but are rejected, while U024D marks missing frames; no bulletin cites U054E itself. Expect third-row folding to stop, to move only partly or to need another relearn.
U054E at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyEasy, DIY possible
- Typical labor0.2 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U054E
- Third-row seats do not fold or unfold electrically
- Seats stop part-way or end up misaligned
Common causes of U054E
- Most likelyPower fold seat module software fault
- PossibleSeat end positions lost after an obstruction event or power loss
- Less likelyHarness to the third-row seats damaged in the cargo area
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.
Parts involved

What each part of U054E means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4E | The exact fault in that area. |
What to do next
- Note U054E 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 U054E
What does U054E mean?
U054E means "Invalid Data Received From Seat Control Module J". Ford calls the module that folds the third-row seats electrically both PFSM and seat control module J (SCMJ). It is a generic code, so it means the same on every make.
Is it safe to drive with U054E?
U054E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U054E fail an emissions test?
U054E 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 U054E to fix?
Difficulty: easy. A typical repair takes 0.2 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U054E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
