Sync 3 update, black screen, Bad APIM

I tried to update my 2018 f150 sync 3 from 3.0 to 3.4 via the usb update. when doing so I saw the update start then my screen went black. I left the usb in for 30min to ensure it was able to finish the update incase I just couldn’t see. I have not pulled the APIM to see it physically but I am able to scan via forscan. I do see the module. I have attempted the restore to asbuilt with forscan as well. the forscan data is :
APIM - Accessory Protocol Interface Module
Part number: JS7T-14G371-JHD
Calibration level: JS7T-14G371-JHF
Strategy : HB5T-14G374-CA
Calibration: HB5T-14G375-BA

Please let me know if I can save this!

Also, I did buy this truck used so I’m not sure the APIM hasn’t been replaced.

Hi there.

Are you willing to unmount the unit to check the sticker?.
Based on the model number, a J series APIM like yours should not be MY20, but Ford started pushing out J series replacement APIM that are in fact MY20.

Detection for these kind of APIMs are user driven, since there’s no real way to know about them beforehand.

Not really, no. If it’s MY20, the unit is dead, even if it’s read by Forscan.
It can be fixed but it requires specialized hardware (and knowledge, of course), so not by the average end user.

I will, I was hoping it wouldn’t come to that. I’m terrified that I’m going to mar up the dash.

Headed to the truck, wish me luck.



While you are at it, can you take a picture of the stickers for both the APIM and screen and share them here?.

If it ends up being a MY20 unit I just wanted to let you know that not all hope is lost as I’ve recently learned how to unbrick them.

I want to make a video on it, but it pretty much requires a bench tester and linux knowledge. For now, I offer a module unbricking service on my site,


That’s good to know!, and both of you are NA based.
It’s good to have options.

Hopefully that works, I’m sure you will confirm that my truck time traveled.

It will only let me imbed 1 picture per comment so I’ll have to separate these.

Sorry for spamming! I just wanted to get these pictures out!

No worries about the spam, I will merge them now to keep the thread organized.

Sadly, yes, that APIM is MY20:

It was manufactured in 2021… (MFG DATE)
I’ve performed a quick search on both the forums and our multiple DBs, and yours is the first one we see with that model number. EDIT/UPDATE, scratch that… There are 2 that were seen before, but we didn’t get any report of them being MY20… I can’t find that model on the forums though…

As I said before, identification of these APIMs are user driven/based and it’s not 100% accurate because of this… Based on your case, this APIM will be flagged as MY20 in the future…

Thank you for the confirmation! I wish I had posted here a month ago instead of trying to figure it out myself for the last month!

looks like I’ll be headed over to

I hope you sort this out soon.

2 final things:

A) I’ve edited my previous response since I did find 2 references to that APIM model in our HW DB, but didn’t get any report of them being MY20… in fact, I cannot find any reference to that APIM model on the forums, except for this thread (which lead me to believe the others didn’t have issues or just reported them in). I’m just saying this in case you missed my on-the-fly edit.

B) Should you get your MY20 APIM back to operational status, there’s a way to reformat MY20 hardware with a different method than Syn3updater: FMODS’ universal reformat package. I’m not sure if this will apply to you though, it would be only relevant if the unit is back at 3.0… moving among 3.4 builds on a NON-NAV APIM like yours does not require reformat, they are just autoinstall.

Any ways, take care and good luck, this will be solved somehow.

Side question, I’ll be shipping my APIM out to @NaviUpgrade, will driving my truck without it installed affect anything?

No hurt to the truck at all!
