U055E Invalid Data Received From Front Controls Interface Module B

Check engine lightUsually off

EmissionsNot relevant

Drive cycleNot required

Limp modeNo

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.

Likely causes

Receiving module configured for different equipment and misreading the panel B data

Software fault in the second control panel

Loose connector or damaged wiring behind the second panel

Symptoms

Switches on the second front panel have no effect
Indicator lamps in the switches do not match the actual function state
