What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Lincoln SSM 53890 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 53890 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 53890 cover?
The manufacturer filed it against 3 model years: 2025 Lincoln Aviator, 2025 Lincoln Nautilus, 2024 Lincoln Nautilus. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
