I've read a few threads on performing the relearn on 2014 Suburban/Yukons. Didn't see a lot of posts, so I thought I'd share my experience.
Had tires rotated during a recent oil change. One tire has a slow leak (I believe it is the the valve stem) which I have not fixed yet. So the next day I check tire pressure in the DIC and the location of the 'leaker' had not changed. So either my leak fixed itself and a new leak was created, or the shop forgot to perform the relearn process....as you might has imagined it was the latter.
Not wanting to spend time taking it back to the shop I decided to figure out how to do the relearn myself. First thing I learned is that newer vehicles require a tool, you can't just let air out of the tires like you used to. Next thing is that the cost of this tool varies immensely, Amazon had models listed in the $80-100 range and Ebay had ones (knock-offs I'm sure) listed in the $9.99 to $20.00 range.
I chose the fiscally responsible (read cheap) option and ordered on from Ebay, for $10.00 from a US seller, as I didn't want to wait for shipping from China. It arrived in ~4 days and totally was a knock-off. The FCID sticker and operating instructions were not applied to the unit and were in the box separately.
Followed instructions for putting the Denali into programming mode (power on and holding both lock/unlock buttons on the fob) and proceeded to reprogram the TPMS, starting with the DS front tire and going clockwise. The 'ol knock-off' performed flawlessly.
