Bulletin Summary
Some 2020-2022-Corsair, 2021-2023 Nautilus, 2020-2024 Navigator/Aviator, and 2021-2024 Mustang Mach-E vehicles equipped with phone-as-a-key may exhibit various phone-as-a-key concerns with diagnostic trouble codes (DTC) U200D:15, U200E:15, U200F:15, B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 stored in the remote function actuator (RFA) module. If any of these DTCs are detected during diagnostics, clear the DTCs, reprogram the RFA to the latest software level and start a new Ford Diagnosis and Repair System (FDRS) session. Verify that DTCs are no longer present. If only the B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 DTCs return in the RFA after a self-test, follow normal Workshop Manual (WSM) diagnostics in Section 419-01. Repair as necessary outside of this article. For claiming, use causal part 14G617 and labor operations 12651D and 12651D4.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
