Your understanding of how this works is not correct.
First, any TPM sensor can be activated however the vehicle is configured. So there is no separate part number for the early Yukons and the later Yukons.
Second, do you know that to get the sensor to learn the position, you have to let air out of the tires? Then, after you've deflated your tires, have to air them up again. The TPM tool takes the place of letting the air out of the tire. You still initiate the process through your dash or remotes or scan tool.
I hope this makes sense.
My kids told me that the TPM tool is the best thing we ever bought for these cars! It was a pain to let out all that air after each tire rotation and then have to fiddle with the air pressures again to get them all aired back up and even again.
