ECU module programming guide using FDRS

[Jesse-Infotainment]

New to the forum here.

I have a ‘21 XLT PB 302A with quite a history. It’s a Job1 truck built in March ‘21. I took delivery in July ‘21. A few weeks after taking it, I noticed the connected services didn’t work. The dealership applied a software update which fixed the connectivity issue… but disabled my heated seats and rear defrost. That became a 5 month saga that ended with a Lemon Law suit, a check from Ford, and a repaired truck (the software they applied for the connectivity issue was for an Ecoboost power train, not PB).

Fast forward another several months and I discovered it wasn’t receiving any updates. Took it to another dealership (we moved), and they diagnosed it as a bad APIM. They replaced it, and while it was in the shop, I got an app notification about the update. That was May ‘22.

On to now: I am still not receiving updates. My truck shows software version 21223_PRODUCT, while PTS shows a previous version. I recently updated all modules wit FDRS/Mongoose.

Everything worked except the APIM. I was able to create the USB. It begins Updating, but eventually I get a Code_0 USB error. Sometimes the error comes up in about 3 minutes, sometimes 20 minutes, or somewhere in between. I’ve tried 2 flash drives from 2 manufactures.

I’ve heard there may have been some bad APIMs from last year. Could that be the case?

I see you tried the PMI. When it created a USB is that the USB that gave teh USB 0 error?

The APIM was never PMi from when it was installed. There is an ESN mismatch being submitted in the network scan. So the issue could be a couple things. The update youre trying to install is taking you backwards from where you are at. The available update is 21146. So it wont allow the install.

You need to complete the PMI and attempt the USB the PMI process creates.


If it still fails then the APIM is the issue. The apims with the USB 0 TSB were shipped at 21223 which was technically a JOB 2 software version at the time.

Either way try to complete the PMI first with the USB created during the PMI

I must have done something wrong with the PMI. I don’t remember it prompting me for a USB.

I see in the logs that it did.

Maybe I missed it. I definitely didn’t use a USB as part of the PMI. So I’ll just do the PMI process under APIM? Do I need to do it for any other modules?

No. Only the apim. The issue of the esn mismatch itself it’s the software you have won’t allow 21146 to be installed over it. So the PMI should prompt you for a version that will.

@jober03 This is why I told you it was outside my scope of knowledge and to post here. ?

Fantastic. If I’m understanding, if it’s successful, I’ll actually be downgrading, then it will allow me to update? Since my current version matches the ones with the USB issue, you’re saying it could possibly be part of that TSB?

Sorry if I’m asking redundant questions… there’s a lot of information out there to sort through

Won’t really be down grading. It’s more of it installing the correct version and getting that synced up with fords servers

Got it. Would that then allow me to update to the newer versions, either via OTO or FDRS?

YEs. THe issue is the apim software version installed is not a proper version for a JOB 1 truck. SO doing a PMI will make software sync up and release the proper version updates.

I wouldnt worry about OTAs... if you have FDRS you need to get it as far along as possible in FDRS then worry about OTAs.

You just need to worry about getting a PMI complete at this point. The rest later. The software mismatch is your issue at this point

I have been working on updates under the SW updates tab for a few hours. Everything is completing so far. (Knock on wood).

I have not seen an update for APIM under that tab yet. Should I expect one or do I do the updates there then select All and run the listed APIM updat there?

Sorry if that is a silly question. The instructions say to go under the SW updates tab so I have been staying in my lane there.

Hard to say without having the vin and knowing what level everything is at.

You’ll have an apim update after the Gateway module (GWM)update showing

 

[Hikari]

Thanks that is what is in progress
