** after writing this up and before posting it, I searched for the 2013 owner's manual for 2500HD - in the paragraph following "about seeing the dealer or purchase the relearn tool" it has the procedure to relearn without using the dealer or the tool. Read a bit further down the third column of pg 10-61, and on to the next page. Now what they have online may be different than what was printed during that production run and placed in glovebox **
I have a 2010 Siverado 1500, and the learning process is fairly quick and easy. I have the base LT version with no special buttons for information. With the other models, to get to the learning/activation of relearn will be different, but the process of going around the truck is the same.
My process is as follows:
- set parking brake
- turn ignition to on
- tap odometer reset until is states it is in the tire position relearn mode, then hold reset stem in to activate (horn chirps)
- start at left (driver's) front and release a little air (hold stem in for about 15 second) from tire until horn chirps
- then go the right (passenger) front, release a little air from tire until horn chirps)
- then right rear (one chirp), left rear (horn chirps twice to confirm end of learning)
- turn ignition off
- check pressure in tires to make sure they are still at the desired pressure
