Service bulletin SSM 53890

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2024-2025 Nautilus and 2025 Aviator vehicles equipped with a 12 channel DSP (minor feature code IDBAV for Nautilus or IDBBJ for Aviator) may exhibit a no audio/sound concern or programmable module installation (PMI) incomplete on a replacement 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. For vehicles with a no sound concern, reprogram the DSP using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. If the no sound concern continues, refer to Workshop Manual, Section 415-00 for further diagnosis. For error messages during PMI of a replacement DSP, attempt PMI again using the latest software level of the FDRS scan tool. For claiming, use causal part 18B849 and labor operations 12651D and 12651D4.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
