Some 2021 Mustang Mach-E/F-150/Edge/Nautilus vehicles equipped with SYNC Gen 4 may experience a USB Error 0 being displayed in the infotainment screen during Programmable Module Installation (PMI) on the replacement accessory protocol interface module (APIM) ordered on 01-Jan-2022 and through 13-Apr-2022. This maybe due to a software issue with the replacement APIM. Order another APIM from Ford Component Sales (FCS). Service stock has been corrected.
