U055E code meaning
Invalid Data Received From Front Controls Interface Module B
What U055E means
Where the front switches are split over two panels, the second one is front controls interface module B. Ford uses exactly this name (FCIMB): on 2023 Transit vans with SYNC 3 Lite, rear-only parking aid and no front sensors, the parking aid disable switch sits in the FCIMB; for vehicles built between mid-March and early June 2023 it did nothing because the park aid module was misconfigured, fixed with the PAM configuration app (SSM 51837). That case shows that a fault visible at panel B can lie with the receiver. U055E covers B-panel frames that arrive with implausible content; U025D marks lost contact and U0557 the main panel A, which on the F-150 could freeze under heavy CAN load (SSM 46902). No bulletin cites U055E. Switches on the second panel may not work.
U055E at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U055E
- Switches on the second front panel have no effect
- Indicator lamps in the switches do not match the actual function state
Common causes of U055E
- PossibleReceiving module configured for different equipment and misreading the panel B data
- PossibleSoftware fault in the second control panel
- Less likelyLoose connector or damaged wiring behind the second panel
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U055E means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5E | The exact fault in that area. |
What to do next
- Note U055E 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 U055E
What does U055E mean?
U055E means "Invalid Data Received From Front Controls Interface Module B". Where the front switches are split over two panels, the second one is front controls interface module B. It is a generic code, so it means the same on every make.
Is it safe to drive with U055E?
U055E does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U055E fail an emissions test?
U055E 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 U055E to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will U055E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
