On June 20, 2025, Ford provided the following information to dealership Service personnel via an Alert issued on the Professional Technician System (PTS) website...

 

Some 2021-2024 Ford and Lincoln vehicles equipped with SYNC 4 may not be able to perform an update to the accessory protocol interface module (APIM). 

This may be due to the software in the APIM. Ford Engineering has de-activated the ability to update these SYNC 4 APIM modules and as applicable, the Ford Diagnosis and Repair System (FDRS)  will not present an update for the APIM module.  Some existing directed repairs may be impacted, check OASIS before attempting any specific TSB repairs and landing pages before attempting any specific FSA repairs.  For any vehicles repairs requiring a software update that includes an APIM update in the programming sequence, if the 5-digit product code for the APIM software is equal to or lower than 23187, do not attempt to update affected modules at this time.  To determine the 5-digit product code for the APIM software on the vehicle,  while the vehicle center display screen is powered up with ignition in run or accessory, go to General Settings > Select About SYNC. Find the 5-digit code, example “ SYNC 4, Software Version: 23187_PRODUCT”.

 

This post will be updated when Ford offers fuller clarity, or, when a remedy is provided by Ford Engineering.
