Let me know if it works for you!I sure hope so!

Holy crap on a cracker! It worked!!!So, here's what I came up with.
Just like most of the other tutorials, you start by opening the BCM, and and modifying your tire size there. I did some GPS calibration for my 235/65/17 AT3Ws, and input the value of 2215 mm's.
After you enter that you write, and move on to the ABS configuration. They have my tire size as an option there so I updated that as well, though this didn't seem to be critical in the process.
After this was done, I cleared errors, and then did the PCM relearn, though the errors popped back up immediately which I expected.
After the reset, the key that I spent 3 hours trying to find is that you now need to re-initialize AWD in the configuration module.
This is the most important part. It re-initializes the AWD info from the central config that you just updated. You do a full restart of the vehicle (wait 3 mins after opening door), then clear errors one last time (likely residual, not showing on dash) and you should be good.
This cleared all of my errors, my fuel economy, and speed are now reading correctly.
The only weird thing is I'm surprised by the tire size in mm that is actually working, so I may toy with it with other speed tools to ensure that it's actually correct.
That said, this all worked for me, and I was good to go after that final bit.
Awesome!!! Very happy to hear as I'll be crossing that bridge some day when I replace the tires on ours.
Now Iām just playing with the circumference to get the speedometer dialed in.
Yea, there's only a certain range programmed into the module. If you go above or below it, you get the code.If I go over 2,500mm I get a reoccurring DTC that will not go away no matter what I try.
So, Iāll take .5 off and happily go about my day
