What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 2025-2026 Navigator vehicles may have diagnostic trouble code (DTC) B14E4:55 stored in the body control module (BCM). The rear turn signals may also flash solid rather than sweeping from inside out when activated. This may be due to replacement of the reversing lamp assembly without performing the "BCM-Local Interconnect Network (LIN) New Module Initialization" application. The Workshop Manual (WSM), Section 417-01 > Removal and Installation procedure has been updated. Using the Ford Diagnostic and Repair System (FDRS), download and run the "BCM-Local Interconnect Network (LIN) New Module Initialization" application. Follow the diagnostic scan tool directions to address this concern. For claiming use causal part 13B433 and labor operations 12651D and 12651D4.
Trouble codes it names: B14E4

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 54969 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 54969 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 54969 cover?
The manufacturer filed it against 2 model years: 2026 Lincoln Navigator, 2025 Lincoln Navigator. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
