My Mustang has been at the dealership for almost two weeks now. My service advisor mentioned something about a new TSB being issued, and needing to get some special hardware, so putting two and two together, I'm guessing it's this. They've had to engage with some tech team for help, and after my particularly spicy Twitter rant the other day, things have been escalated on that side as well. My service department's latest gambit is to just stop answering the phone for either myself or Ford, so things are now getting escalated.

I'm hoping to get my car back next week, but I don't have a lot of hope. What I do have is a quote to sell the damn thing, because I'm done with all of this.
My lemon law buyback is scheduled for next week (numerous issues including this). I probably could have forecasted a fix coming a few days before. Not sure if you’d qualify for a lemon, but worth taking a look.

Do you get a fair deal for a buyback? Wish they had other cars lined up to give people, I just wouldn’t wanna lose my MME

Bypassing the USB hub has nothing to do with the issue. Its just part of the solution.

Bypassing the USB hub just takes out one layer of potential issues when doing this update. This fastboot process is connecting directly to the module and writing the data directly to the memory of it, instead of doing a normal update process. It more like doing re-image of a computer.

Also, with the ethernet part, there is always a risk the USB hub would cause the usb to ethernet adapter to not be recognized by the car or cause some data corruption.

My guess is you could just plug into the USB hub and it would work fine, but its easy enough to bypass it in the Mach E so they just have you do it to be extra safe.
I agree. Since F150s without a console have both methods through the Media Hub, connecting directly to the APIM takes away one potential problem area. I looked at the WSM and the Media Hub USB only goes to the APIM.

It indicates that the APIM is involved with USB updates of the APIM, TCU, and other modules. Maybe the APIM sends the files to the GWM and the GWM distributes it to the modules.

The internal single twisted pair Ethernet is likely 100Base-T1 (IEEE 802.3bw). The GWM likely acts as a network switch as well as being an endpoint.

I suspect the USB Ethernet is bridged through the APIM to connect the FDRS laptop to the internal single twisted pair Ethernet. Then the FDRS laptop can communicate with the TCU.

I got the adapter, cable, and USB Ethernet dongle today. I do not need it, but I may need it in the future.

The terms are generally mandated by the state of purchase lemon laws. Ohio for instance is the full amount including tax, etc

I had ProximusAI kindly pull up my FDRS info. They haven't performed the 22-2217 fix, even though the garage said they had done it for me. So I am contacting them today to tell them they need to do it. Bloody annoying waste of my time!

You may want to have a conversation with your dealer to ensure that they have read the TSB and that they have the special tools required to complete this repair.

1648133482137.png
I went in to my dealer yesterday with the TSB 22-2117 printed out. You would think I was speaking a foreign language; nobody in the Service Department had heard of it. I asked if they had the special adapters required and they looked at me like a deer in the headlights. They shuffled me off to the Parts Department and Parts once again knew nothing about it and wondered what I was doing there. I explained that Service sent me over so they took the TSB and went back to Service. He came back a little while later and told me the mechanic who does the work will have to look at the TSB to see if they have the necessary adapters. He printed off his own copy of the TSB and said he would show the mechanic and then somebody would call me. I told him I have an appointment next Tuesday and want to be sure they are ready to do the work otherwise I'll reschedule it. He told me he would call but so far nothing. This does not instill a lot of confidence in the Service Department. Once again, members of this forum are much more knowledgeable about the TSB's for our cars and it gets old having to check up on them all of the time to be sure everyone is on the same page (OK, I know it's a recently released TSB but when I come in with it and it clearly states what is needed they ought to be able to at least give me some answers).

As far as the necessary adapters, will both the USB connection (on the laptop) and the Ethernet connection (on the laptop) be used to address the two separate modules (APIM and TCU) with the necessary adapters or will they use one or the other depending on the error message they receive? I'm unclear on this part of the procedure. I was on Amazon and saw the Startech USB31000S USB 3.0 adapter and several other ones but I don't recall seeing the Trendnet. Are all of the adapters shown (USB to Ethernet) adequate for the job or only the ones the TSB mentions?

The APIM has to have the correct drivers for the USB device. Here is a Trendnet that is specified.

Thank you for pointing out the correct Trendnet adapter but I still don't understand if the APIM module will use this Ethernet to USB adapter (Trendnet) or just a USB connection using only the mini 5 pin and the male to male USB cord? It states there are 2 ways to connect the laptop and I would like to know if both are necessary or only one. Sorry I'm not trying to be difficult I just don't understand the procedure.

Both will likely be used, just not at the same time.

Thank you for clearing that up for me. That means they need all of the adapters before they attempt to do the work just as I thought.

7. The FDRS will prompt installation of either USB or ethernet cable connections based on the failure detected.

Thanks, I saw that. But it didn't say if only one or the other will be used when the error is detected. It sounds like from what it says and you're quoting that either one or the other will be used but not both. That's where I am having the confusion as another answer I got was they would both be used.

I suspect one or the other or both could be used. Regardless, there's no way to know without trying it, so the dealer should have all of the cables and adapters detailed in the TSB.

Well I definitely agree that they should have everything listed in the TSB available and whether it's one or the other or BOTH I guess I don't need to understand why. However, I'm just curious as I like to know what's going on especially if they try to tell me something I know is wrong. It sounds like they are addressing the APIM module and the TCU module and perhaps they need a connection which is different for the two modules. This is above my pay grade and I really don't understand all that is involved.

The way they stated it sounds like they have run into multiple problems that result in the same behavior. Thus the ambiguity in the TSB.
