Thank you. I will have a look at them and will report back with my next steps.

I finally finished up verifying what I was told in order to provide the narrative as accurately as possible as to the 'fix'.

So after inspecting every connection I physically could and finding no issues, I dropped my truck off at the local dealer last Monday the 7th, so they could try to diagnose the issue. The tech called me a few hours later and I gave him as much info as I could over the phone and directed him to the videos and this thread. He passed on looking at them. Towards the end of the conversation, he had handed the phone back to the service writer and I overheard him say "I'm not sure where to go with this from here.", since he had apparently pulled the codes and had already checked the obvious and he couldn't find the issue. I did not hear back from them until Saturday the 12th when I was told it was done. After talking to the service writer, I was told that they needed to perform a PMI on the GWM and after rebooting, everything worked. Hmm. At one point, offhandedly, the service writer mentioned "Ford" said it needed a PMI. So, while I do not know for certain, it appears they were stumped and asked for help from Ford and that's why they had it for a work week to do a PMI/reboot. Ofc, I mentioned I had already done that and when I got back home, I verified all the As Built data I installed by hand before taking it to the dealer was exactly the same as it has in it now. I thought perhaps I had faulty data. After I did the PMI/reboot myself and in one of the various attempts to try to figure out the problem, I verified the data was correct a 2nd time back then as well. So, I'm quite perplexed how the PMI/reboot I did, did not 'work' and theirs did. I have no theory on this. Needless to say, everything does in fact work as it should and there are no codes. So, in the end, it was the GWM all along.

I'm going to update the 1st message in this thread with the solution so readers in the future will know without having to read the whole thread. Truly not sure why others cannot take the few minutes to do this, but here we are.

Thank you very much to 52merc and Bluegrass. Your time and expertise is very much appreciated. If you're ever in the Daytona Beach area, i'd love to buy you a beer or coffee, so please drop me a line. Thank you, again.

Sometimes we all have to go through times like this and learn something from things we can't see.
Passing off to someone else is tough, since they have to begin from a new start on it.
Good you got fixed up.
Good luck.

Glad it finally worked for you. I appologise I went AWOL on you for a while. Had some health issues and had a triple bypass operation on 04-Jul-25. I sure felt it had something to do with the GWM.

Thanks. The heart is good and strong and the Docs all said the recovery should be complete. Just a bit tired and sore right now.

No apologies necessary and you were right. I'm happy to hear you are on the road to recovery. You're in my prayers. Thank you, again.
