SSM 522252024-02-06. Service bulletin. EQUIPMENT:APPLIANCE:TV/RADIO/SPEAKERS. Some 2023 Bronco vehicles equipped with a B&O sound system and built on 28-Jul-2023 and through 29-Aug-2023 may experience an intermittent loss of audio from certain speakers. Function should return with a key cycle and the symptom may return within every 1-20 additional key cycles. This may be due to the software within the audio digital signal processing module (DSP). To correct the condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System (FDRS) diagnostic scan tool. For claiming, use causal part 18B849 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB 23-24372024-02-06. Service bulletin. ELECTRICAL SYSTEM. This article supersedes 23-2105 to update the vehicle model years affected and customer symptoms. Some 2021-2023 Bronco vehicles may experience at least one of the following symptoms: intermittent blank/frozen center display screen that resets automatically, Android Auto Apple Carplay connectivity, checkerboard display, center display screen reset and/or Bluetooth connectivity.

Make sure the proper procedure is being followed to exit neutral tow mode by referring to the Owner's Manual > Towing Your Vehicle > Recreationally Towing Your Vehicle. Make sure the vehicle's battery is fully charged and then diagnose all diagnostic trouble codes (DTCs) in the AWD module. Refer to Workshop Manual (WSM), Section 307-07A. If diagnostics do not resolve the concern or there are no DTCs present in the AWD module, reprogram the AWD module using the latest software level of the Ford Diagnosis and Repair System (FDRS) diagnostic scan tool. Refer to the appropriate section of the WSM. Once the repair is complete, verify the vehicle's ability to successfully enter and exit neutral tow mode by cycling the vehicle in and out of neutral tow mode a minimum of two times, allowing the vehicle to enter sleep mode (key-off for at least 5 minutes) be
