Just chiming in to say that I also got this “service vehicle soon” and “check 4x4” message when I was screwing around in the pro cal tool. I accidentally initiated the change tire size function when I was looking around in the menus. I tried to clear the code with no results and I also tried to remove the battery cable to reset it. Nothing worked. Oddly enough, I drove the truck around and all the drivetrain worked fine. 2H, 4 high, 4auto, and 4Lo.
I stumbled upon this thread and realized that I just had to go through the process of the tire / gear learn procedure following the prompts on the procal tool. Fixed in like 2 minutes

Exact same thing happened to me, except I dropped it off at the dealer before I did the search that led me to this. Went into tire/gear on my procal box and then escaped with no change. boom: CEL. Now to try to convince the dealer to just do the fix without taking too much time. (Still covered under warranty in any case)

Update: Told the dealer I could fix it. They let me give it a try and five minutes later code was cleared and I was ready to go. Simply had to use the pro cal box to go into tire size and reload the default tire size and let it do its thing. Such a weird error.

Ford ranger procal tune 2.7l XLT, so I did all the downloading to the procal and sign in my account and everything seem all good and today I went to my dealership so the guy just plugs it in and install the tune (I did all of the work before hands) and he installs it and it gives him a fault code U2101. I know it a fairly new tune, just wondering if anyone had that before.
