Review on 🔧 JDIAG EL-50448: The Ultimate TPMS Relearn Tool for GM Auto Tire Pressure Monitor System Sensor Activation - TPMS Reset Tool OEC-T5 for GM/Buick/Chevy/Cadillac Series Vehicles 2021 Edition by Brandon Boones

I used this once on my 2014 Traverse and was able to get it to work. The only snag I ran into was that the first tire (front left) you start the retraining process with originally had the 6 o'clock valve stem. I couldn't get it to work and after playing with it for a few minutes I decided to see if changing the valve stem position would make a difference. I moved the machine to set the steam valve to the 12 o'clock position and it worked great. I should note that some of the others, after spotting the first tire, had their valve stem at 4 o'clock and 6 o'clock and were working as expected. I'm not sure if my first experience applies to future attempts to use this, but thought I'd pass it on in case anyone else comes across the same thing on their first use.
