SSM 545912026-03-03. Service bulletin. ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2024-2026 Nautilus non-hybrid and 2025-2026 Aviator/Navigator vehicles equipped with 28 radio speakers (minor feature code IDBBN) may exhibit a no audio/sound condition with no communication with the audio digital signal processing (DSP) module. Remove the DSP fuse from the battery junction box (BCMC) (F40 for Aviator, F5 for Navigator, F138 for Nautilus). Inspect the fuse for an open and ensure the fuse has proper blade contact. After one minute, reinstall the good fuse. If the concern is still present or a fuse concern is found, continue with normal Workshop Manual (WSM) diagnostics, Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing. If communication has been re-established with the DSP module, engineering is currently working on a solution for this condition that is expected by Q2 2026. Replacement or reprogramming of the DSP will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. For claiming, use causal part 18B849
SSM 545832026-02-17. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM.

Examples include auto folding not operating when the switch is enabled and/or auto folding continuing to function when the switch is disabled. This may be due to the software in the driver door module (DDM) and passenger door module (PDM). Power folding mirror operation from the physical button is not affected by this condition. Inform customers that engineering is currently working on a solution for this condition that is expected in Q4 2026. Replacement or reprogramming of the accessory protocol interface module (APIM), DDM, or PDM will not resolve this condition.

This may be due to the supplemental braking system keeping the vehicle awake during brake applications. Advise customers that while recreational towing the vehicle with a supplemental braking system installed, it is recommended to use a 12-volt battery charger connected to a power source external to the vehicle being towed. The Owners Manual is in process of being updated with this information.
SSM 542272025-09-23. Service bulletin. ELECTRICAL SYSTEM. Some 2024-2025 Nautilus and 2025 Explorer/Aviator/Expedition/Navigator vehicles equipped with Ford/Lincoln Digital Experience may exhibit a "Map Source Not Available" message on the instrument panel cluster display (IPC) when using Google Maps via Apple CarPlay®. Google Maps does not yet support displaying the navigation map on the IPC within the Apple CarPlay® environment and this is currently the expected behavior. Replacing or reprogramming the accessory protocol interface module (APIM) will not resolve this condition and no diagnosis or repair is necessary. Inform the customer that a future Google Maps update for iPhone is anticipated to enable this functionality.
