Special Service Message 53966 - 2021-2025 Various Vehicles - SYNC4 - General System Performance And Stability - Programming No Longer Available

Jun 20 2025 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”.

I think that’s the version I’m on.. when did they post this message? Jun 20 2025 seems like a while ago.

Maybe I'll email Louis Rossman and send him my login on these forums and let him read through the 1000s of fixes I've done and see maybe of he wants to do a video on it.

I vote that we all go and sit in Jim Farley's office

Its so crazy.. I helped MANY people get passed that version when I could. There is literally no reason they cant release the updates.

I would love to hear it..

I just know back when I could Once the gateway installed, it was LkJ strategy file that had to be updated for the ICE trucks. Once it reported all updates came after. No install issues and in fact a few got the EL APIM update via OTA. Every Truck as soon a LKJ was reported as the strategy the update sequence hit no issues. I helped a few Mach E get passed it also. I want to say it was LKJ for the Mach E also.

Oh well Im sure there is a reason. I never encountered a reason to not do them though.
