I was playing around with the tire pressure relearn operation not realizing that it was going to screw up my sensors, but after a little search on google and less then 5min I was able to relearn without the tool.
It's very simple. All you have to do is as soon as you press the relearn button and after the horn beep twice start on your front driver wheel-front pass wheel-rear pass wheel-rear driver wheel. You have 2 min to put in air on each tire and the horn will beep once each time you are successful, but don't wait to hear the horn beep and instead just keep working on each wheel. All it really need is for the tires to sense that you are putting in air. I would just check the tire pressure manually before doing the relearn then after it's complete you can put in more air or take out air and do as you like.
Piece of cake. No need to purchase a tool for something you can do in 5min
