Glad y’all figured it out. Now if only there was a button to turn the whole thing off😉

 

I wish they had replacable batteries, I have 2 that check out when then cold guess they I should just replace the set in the near future. This might be somewhat of an issue are there is 2 different part numbers and I really don't know which ones GM used.

I am gonna check the spare which is no longer mounted and has no tire on it. Perhaps there's a part number on it. As I understand it they used 2 different models both ones have different frequencies, if you get the wrong set they won't talk.

I have to agree with you Gavin, and off switch or menu item to disable would have been nice. lol

 

03 do not have TPMS. what year did they add them?second gen?
