Requesting help to debrick my APIM

Bruzer · 3 June 2025 01:48

I’m trying to use FORscan and the procedure at APIM Firmware Flash Rescue to debrick my APIM. I verified that my APIM is pre-MY20 (Mfg date is Aug 2019). I was using Syn3 Updater to update the nav from NA 2 23 to NA 2 24. The update started fine, but when I checked later, the screen was black. I didn’t have a battery charger in place during the update, so it’s likely that there was a low voltage condition which caused the bricking. I have some screen shots of the FORscan APIM firmware update that I’ve been trying to do.

SYNC Region: NA

Navigation Variant: Nav

Manufacturer Year: Pre MY20

Install Type: Retrofit

Old SYNC Version: 3.4.23188

New SYNC Version: 3.4.23188

Do you have a error message, if so what is it?
Not that I’m aware of.

Update Method: CyanLabs Syn3 Updater

Syn3 Updater Version: 2.13.3.0

FORscan screen shot #1:

A couple file differences:

Calibration (F124) should be 1U5T-14G375-DA.VBF, since I have NAV, but I was not able to get that to download.

ECU Illumination (F16B) should be JB5T-14G379-BA, but I was not able to get that to download either.

Thank you!

F150Chief · 3 June 2025 02:39

KU5T-14G371-CDE is 32GB Nav APIM. not MY20+.

Trying to update the firmware will not unbrick the APIM. This is a software issue, not firmware.
Most likely, you can run the procedure again and it might succeed.
When you boot the APIM does it come back to black screen or does it show the splash scrren then go to black?
Does the reformat screen show at any time?

Bruzer · 3 June 2025 04:44

Thanks F150Chief. That’s encouraging to hear that it’s a software issue. Just so I understand, when you say “run the procedure again”, are you saying to just insert the USB drive again in the truck and see whether it runs the update successfully? In it’s current state, the screen is totally blank the entire time (when I open the door, when I start the truck, etc.). I’m busy the next day and a half, but I’ll report back when I can.

F150Chief · 3 June 2025 15:57

So it’s obvious this is not the OEM APIM in the truck as it is reported to be a K-series and you have a 2015 F-150. Was this a replacement for Sync 2?

The APIM should have this from the factory:
3.2/3.3 APIM NAV & NON-NAV Unit Firmware (Production Release, 2018.5, Late J thru K Series)
Secondary Boot Loader: GB5T-14G376-AA
Strategy (F188): 1U5T-14G374-DA (6/27/2018)
Calibration (F124): 1U5T-14G375-DA (NAV) / 1U5T-14G375-CA (NON-NAV)
ECU Configuration/Sound Profiles (F10A): GB5T-14G379-AA
ECU Configuration/Illumination Strategy (F16B): JB5T-14G379-BA (6/7/2018)

The image does not show this, but shows a mix of older and newer firmware. A K-series should have been loaded with the Illumination strategy above. I would recommend you try to load the proper firmware for the unit. This is usually not how to debrick a unit, but this looks like it just might be a driver issue.

But, before you do that, see if the unit will actually work. Connect with FORScan and reset the APIM via the tools menu. If it actually reboots it might bring up the screen. Also, disconntecting power for 5 minutes might jump start it also.

Bruzer · 3 June 2025 23:49

Yes, the APIM was part of a Sync 3 upgrade kit, so it’s not the OEM APIM.

I had indicated in my original message that in trying to follow the APIM Firmware Flash Rescue procedure, there were a couple files that I needed, but hadn’t been able to get them to download:

Calibration (F124) should be 1U5T-14G375-DA.VBF, since I have NAV, but I was not able to get that to download.

ECU Illumination (F16B) should be JB5T-14G379-BA, but I was not able to get that to download either.

Would you be able to provide those files?

As you suggested, before I try to update to the correct firmware versions, I’ll try both the APIM reset with FORScan, and disconnecting the power. I’ll report back with my results.

Thanks again.

F150Chief · 4 June 2025 00:04

See your PM…

Bruzer · 4 June 2025 01:34

I tried both the APIM reset using FORScan, and disconnecting the power, but neither of them brought the screen back to life. I even plugged the USB drive back in (with the battery charger in place), came back 40 minutes later, reset the APIM, but still blank. I’ll move on to getting the correct firmware files loaded in the APIM and report back.

bill32399 · 4 June 2025 02:33

Do you by chance have a picture of the sticker on the APIM?

Bruzer · 4 June 2025 20:58

Yes I do:

F150Chief · 4 June 2025 21:40

The Assembly Part Number on the APIM LS7T-14G370-BCG would be equipped with a 5U5T-14G371-CKC or similar unit. Not a K-series…however, this is a legit unit from a 2020 Fusion, last year of production, so Ford just uses what they have. KU5T-14G371-CDE is the part number for the APIM itself. This is shown above on your FORScan screen.

Were you able to program the firmware?

Bruzer · 4 June 2025 22:28

Thanks F150Chief. I just finished with my attempt to program the APIM with correct file versions. Unfortunately, still blank. Here’s what FORScan shows:

I also did a reset of the APIM several times.

At this point, if there is nothing else to try, the vendor that provided the Sync 3 upgrade kit is willing to have me send the APIM back to him to see if he can get it working. He says he uses Ford IDS, and has had decent success in unbricking APIMs. Should I go that route?

bill32399 · 5 June 2025 01:27

Oh good, I was worried you had a Chinese garbage one but you don’t. If he swaps it tell him to send you another K series APIM.

Bruzer · 5 June 2025 22:43

I decided to ship the APIM back to the vendor, to see if he’s able to restore it. I also included the request to send another K series APIM, in case he needs to swap it. If you’re OK leaving this topic open, I’ll update it with what the final resolution was.

lolford · 25 June 2025 02:55

Sorry to bump the thread but did the seller ever give an update?

Bruzer · 25 June 2025 21:15

Thanks for the thread bump. I just got the issue resolved, so here’s the summary:

Despite my best efforts, I couldn’t get the display to work with the original APIM. I sent the APIM back (to Mitral @ AllThingsSync). When he tested it, he said he was getting memory errors with both IDS and FORScan. He also said that he took the APIM to Ford, and they were able to get a little further to where the memory was being read and they were trying to format it. However, in the end, they were unsuccesful in bringing it back to life.

He sent a different APIM out for me to try. After reconnecting everything, I still had a blank screen. I then decided to disconnect/reconnect all of the connections to the wiring harness. Surprisingly, everything now works correctly! I suspect that I didn’t have a good connection to the T-connector that goes to the ACM (below the display/APIM). When I was redoing the connections, I thought it was making good contact, but it kept separating. I found that I really had to press the 2 connectors together very tightly in order for them to stay connected.

I think the first APIM got messed up because I was using Syn3Updater (to update the Sync3 and NAV versions), but the engine wasn’t on and I didn’t have the battery on a charger. Lesson learned!

Thanks again to F150Chief and bill32399 for your help.
