Bulletin number: SSM 52328
Component: Equipment: electrical: infotainment: software
Summary: Some 2021-2024 Bronco/F-150, 2023-2024 Escape/F-Super Duty vehicles equipped with SYNC 4 may experience a concern during accessory protocol interface module (APIM) programming where the vehicle's center display screen indicates USB Error. This may be due to a lack of memory space available to perform the APIM software update. If it is a memory concern, the Ford Diagnosis and Repair System (FDRS) will provide an option to delete the voice application. Re-enter the module programming and when prompted, do not select first option - SYNC Module (APIM) Software Update, select the second option - Delete Voice Application(s) From Module. Once deleted, run the SYNC Module (APIM) Software Update as directed, this will update the software and automatically reload the voice app. If the voice delete option is not available, continue with normal diagnostics in the Workshop Manual, Section 418.
