Hello from OKC OKlahoma

Bought my Hummer in 2012, wished I had gotten one sooner! Need help with damn TPM Service. Tried resetting tire pressure back passenger's tire won't register any ideas?

Welcome. My sensors came loose inside the tire and had to be replaced. Not sure what your issue may be. Also sometimes takes our H3 a couple of cycles to reset.
