SSM 549692026-06-29. Service bulletin. ENGINE; EXTERIOR LIGHTING. Some 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.
