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

I bought this re-learn tool but I'm having trouble starting the device. Work. After several unsuccessful attempts, I contacted the seller. They suggested I try a few more things, which I did - it still didn't work. I reported the results to the seller and he immediately sent me a replacement unit. The replacement device worked right away and I am very satisfied with the result. the performance of the relearning tool. The customer support response was GREAT and made up for the issue I had with my first device purchase. So I give the overall experience 4 stars - it works and I'm happy. My advice: follow these instructions carefully, if it doesn't work ask for help.
