If you don't want to do the tire pressure up/down pressure method to reset your TPMS sensors, you can buy one of these TPMS tools, upload this applicable software, and you're good to go.

http://forums.corvetteforum.com/show...highlight=tpms

Just thought someone here might be interested. It's mainly a Corvette issue, but if you want it to work with a Tahoe you may want this J-46079 tool and v.3.3 software update.

Hope someone finds this helpful.
