Official summary
Some 2021-2024 Mustang Mach-E, 2025-2026 Navigator and 2024 F-150 vehicles may exhibit inoperative welcome/approach detection lights. This may be due to the body control module (BCM) software. To correct the condition, download and run the "BCM - Programmable Module Installation (PMI)" application using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. If the condition persists after PMI, refer to Workshop Manual (WSM), Section 417-01 for normal diagnostics and repair as necessary outside of this article. For claiming, use causal part 15604 and labor operation
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
