Good afternoon yall, I have a 2007.5 GMC 2500 regular cab long box 4x4 with the 6.0 gasser. I have been infuriated with the electronics on this vehicle. The TPMS light flashes then is solid with the DIC saying “service tire monitoring system”. I have 4 new sensors, all good batteries. OEM rims with new HT2 tires. The positions have been correctly relearned and the tires have the correct amount of air in them. The annoying thing is when the TPMS light turns off, the airbag light turns on saying I have a short in my seatbelt tensioner. Then a few days later the airbag light turns off and the TPMS light turns back on. I am pulling my hair out trying to figure this one out. Any help/insight is greatly appreciated.
