ECU module programming guide using FDRS

[20ecoboost21]

Say I made changes in the BCM, IPC, and APIM with Forscan and want to revert back to stock but didn't save the stock files. Is there a way to revert back to stock? I'm still having issues where the GWM won't update even though I'm getting the USB update successful message. I'm thinking maybe the Forscan changes may be interfering but not 100% sure. Here's my software part #'s if this helps.

You GWM looks very similar to where my IPC got stuck. A MU5T number in one column and a ML3T in the other column. In theory a PMI should be able to correct this by wiping the whole thing away and restoring a last know good configuration, but unfortunately that doesn't appear to be the way and PMI really works in FDRS. I'm not sure what the solution is, but based on my experience that is what you need to be troubleshooting.

If you didn't take backups of your as-built before you started ForScan changes this it will be very hard to put things back like they were. The how-to guide in the forum walks you through making the backups, and I keep mine stored in about 4 spots in case I ever need them.

@Jesse-Infotainment, Is there a way to reinitiate the IPC update? My whole update was over CAN, never an option for USB during the install. It took about 6.5 hrs as most here have been saying to complete. I do not recall any DTC's after update.

Yes same for me on IPC. Why re-initiate it though mine seems updated ok.

Just need to figure out how to start getting past 21281 now…

*Edit ah just saw @Jesse-Infotainment latest and seems like a bunch of us all stuck here so if any XLT guys fully updated can help ?

If you’re having issue with usb you can fail it and say no it was not successful and force a canbus update on the gateway.

This is what I did to get past the TCU update. It took forever but it passes.

Gateway is fast its smaller fortunately

If ive never had any apim updates, theoretically my original as built files from months ago should still be safe to revert back to right? I think my only change to the apim that i can remember was the automatic heated seats and global windows. I just dont remember the original values. How can i find my original as built files in forscan? Im pretty sure i did a backup before making changes i just dont know where i saved it to.

Ok ... When I started I had tons of updates. Sorry forgot to screenshot or count before diving in. After banging my head on my steering wheel for the better part of the last 24 hours, I have gotten them all updated ... minus one that completes but never seems to go away.

Now that I am done I am experiencing 2 issues (in FDRS ... not impacting anything that I can tell in the truck): ICM

and CMR: again ... all cameras and lights working fine.

Also, even after all of that GWM and APIM updating ... I am still on SYNC 2.1 (BIG SADFACE).

Any idea how I can clear these issues and maybe shake loose any other sync updates? Note that my truck was literally one of the first off the lines as I bought it in 12/2020. full prep package.

Thanks

For reference: here are my sync version screens:

You have the same issue as the others with the update not completing.

Need to see what your files are. do a network scan go to IPC see what files are actually loaded.

When you go to FDRS and it shows the list of modules select the IPC and scroll down and show what the files are.

this is EXACTLY where I got stuck. You will need help from someone who can side load your IPC. Be patient and hope they reach out to you.

Can you send me your VIN so I can check something?

I don't recall seeing this in earlier posts, but just a little something I discovered tonight.

For those of you who have BlueCruise hardware, are fully updated, but your truck does NOT kick into blue cruise on the freeway: check your connectivity settings!

I had bluecruise after all the updates, but reset my APIM and sync system when diagnosing camera issues with Jesse. For the last day, BlueCruise wouldn't kick in despite proper cruise settings being set. Once I flipped everything to ON under connectivity, I got a FP app alert that my BlueCruise was now ready (second time getting this alert). Bam, BlueCruise worked flawlessly!

Hope this helps!

you could check 1FTFW1E84MKE02174 as I am in the exact same state as Ebrou? ?
