That’s the problem, they all check out ok now. No damage whatsoever that I or the dealership could find. They looked it over and just gave me the truck back.

That's gotta be a software bug then...some combination of wheelspin, turning, etc that makes the wss's read something the computer doesn't understand. I haven't experienced it yet, but I believe you guys that say you have!
I believe it’s software as well but a fix is desperately needed as this code left me virtually stranded. I really lucked up and had some side by sides winch me up the last big obstacle and I was able to force my way over everything else. It was a tough blow because I went from overly confident in the truck to questioning if it’s safe to trail ride in. This had the potential to leave me, and my family, stranded overnight. I was on this trail 9.5 hours and only saw these 4 side by sides all day.

You should have an OBDII code reader and try to clear the codes next time. I always have one with me, whether it be Forscan Lite or my dedicated OBD scanner. I bet you tripped them up and through a code yet everything was fine. Sometimes codes will clear themselves but need time/miles to figure out all is well. You could do that right then and there.

Did you try disconnecting and reconnecting the battery? That should clear the codes if it's a glitch, or like @orion said, a cheap portable obd tool. I used to have one that Bluetoothed to my phone. Somebody borrowed it, and they need it more than me I guess!

I've yet to have to clear a code since getting Forscan, but yeah, it should work.

is there a TSB for 4A controller module replacement? I read sometimes they weren't disengaging as intended. I complained about the 4A seeming like its always engaed on front, dealer told me 4A isnt for pavement to which i had to argue yes it is. Its 4 advanced 4x4 AWD. They basically ignored me asking them about how i felt it was super noisy. On top of this im also having 7 speed manual transmission noises and last night she grinded in 2nd for no reason while already in gear.. No reliable fix for that yet from FORD..... :0

any chance you could show me where the tcase range sensor is on our advanced tcase? Is it also called the position solenoid??4A is an encoder motor also, it's mounted on the front of the case instead of the rear. No way you could get vise grips in there, but looks like the right allen socket could do it. W/that motor not mounted tho, idk what keeps the linkage from vibrating into a different position, possibly neutral, wouldn't be something I'd wana do on the trail unless totally out of options. The part time xfer case looks way easier...here's pics, 1st the 4A:
Now the part time case. Looks like you could shift it w/a screwdriver, but how to keep it locked in position? Might be a strong enough detent to hold it in each position, but I doubt it!

It’s on top near the rear.
Disconnect the transfer case range sensor connector and detach the wiring harness retainer clip from the transfer case.

Remove the transfer case range sensor retainers and remove the transfer case range sensor cover.

Awesome thank you! Any chance you have the ability to get the part number?It’s on top near the rear.

You’ll probably need to lower the transfer case to get at it.
I know I’m bringing an old thread back to life. Spare me the forum comments of “this is an old thread. Start a new one” or “why didn’t you just do a search”
Just doing a deep dive into the transfer case and some recent issues we were having. And we literally had our laptop out with Forscan to get things going again.

What did you have to do in forscan and what was the error/codes you were getting? It might help others in the future!
