Review on 🔧 Upgrade Edition JDIAG TPMS Relearn Tool for GM and Ford Vehicles: Super EL50448 Auto Tire Pressure Monitor Sensor Activation Reset by Jason Cox

When I first pressed it against the sidewall of the tire, the antenna came loose. After that I couldn't activate any of the TPMS sensors. EDIT: Upgraded to 4 stars. I used this on another car (GM) and it worked exactly as intended although the antenna was broken. I can't give 5 stars because the antenna broke the first time I used it. Given that 4 sensors were successfully activated afterwards, I admit it was a good buy.
