What is interesting is that I never had the U05 recall done on my 2017. I could swear since I had the truck from new, it would allow me to back up with the door open, seatbelt off and truck in Reverse.
Then I had the U61 (cruise control) recall done. And ever since then I now have "AutoPark" functionality. No one did the U05 update, Im sure of it because I was told it would take at least an hour for my truck configuration and I was only at the dealer for 15 minutes to get the cruise control fixed.
So Im thinking something in the cruise control can "flip the bit" to enable AutoPark on some trucks. At some point during MY17 production, they added AutoPark code into the computers but did not enable it from the factory. Before that time, there was NO code in the computers for AutoPark.
Some trucks need the bit flipped to enable it and some trucks need all of the code added and enabled. I think my truck was one that just needed the bit flipped and a newer updated (cruise control) did it. Now if I go in for U05 they will probably run it and see nothing is necessary.
Im not happy about it, but I would have gotten the cruise control update no matter what, so it is what it is. Still holding out hope that the AlfaOBD dev can find a way to disable it (if indeed there is a bit to flip, hopefully he can provide access for us to flip it ourselves)
