Haz Posted February 13 Report Share Posted February 13 (edited) SSM 53377 2024 Nautilus, 2025 Aviator - No Audio/Sound - 24 Channel Audio Digital Signal Processing Module (DSP) (Minor Feature Code IDBBN) No Communication Some 2024 Nautilus and 2025 Aviator vehicles equipped with a 24 channel audio digital signal processing module (DSP) (minor feature code IDBBN) may exhibit a no audio/sound condition with no communication with DSP. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS). This concern may be due to software in the DSP. To determine if it is a software concern, remove the DSP fuse, F40 for Aviator or F138 for Nautilus, and inspect the fuse for an open and make sure 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 diagnostics, Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing. If communication has been re-established with the DSP, reprogram the DSP using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 18B849 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual. The involved audio system is the Revel Ultima 3D with 28-speakers, installed on 2024 Nautilus Reserve III 203A and 2024 Nautilus Black Label editions...
