I was on the gm tpm site it can be a dead battery or a blocked sensor that means removal of tires from rim and replace the unit...To diagnose the problem with a tool that reads the tpm without removal... I hope its under warranty... Has anyone had any problems with this tpm device?<img src='

Most likely its a problem with one of the sensors. Some others on another forum have had this issue. What year is your truck? I heard the sensors have an internal battery and they have a life span of about 4-5yrs. Or it could just be faulty. I replaced a sensor on my truck and it cost me $40.

Followed GM tech at Auto shows advice dropped air pressure and brought it back since no more TPM messages. also probably ice and stuff around ring pickup causing bad reads.

Okay took Rhino into Roy Foss when it recoded again ( luckily just before new vehicle warranty died GMPP waranty would cover over 100 cost but still nice for free. problem was the left front tire pressure sensor which was replaced total down time about an hour PS all Hummer owners should check out the H2 Grill for hummer pics and graphics also they still have Hummer stuff (Hats and maglights etc) for sale.
