TPM light on 2006 Hummer H3

Hit a pothole in the road and the TPM service light came on. Checked air in tires and eventually put on new tires, but light still comes on. What is the trick to get the light to reset?

Chances are, one of the TPMS sensors is damaged and/or malfunctioning. The only way to verify this is to have a shop with the proper diagnostic equipment (for TPMS systems) check each sensor for proper function.
I have had the same problem since the day I bought my H3. I have had it in the shop on 3-4 different occasions. The guys have told me that there isn't anything wrong with my TPM sensors & that H3's are bad for this problem. Once the cold weather set in, it is now saying "low tire" and flashing from low tire to the TPM thing and The ( ! ) thingy is also lit up. we have tried to reprogram it the way it says to in the manual and that doesn't work! A mechanic friend of mine says you have to have a special type of tool to reprogram the TPM sensors. All I know is the lights on is driving me crazy! It's good to know that I am not the only one having this problem. :/
