JDIAG EL-50448 TPMS Relearn Tool for Auto Tire Pressure Monitor System Sensor Activation TPMS Reset Tool OEC-T5 for Buick/Chevy/Cadillac Series Vehicles 2024 Edition

Easily used. Worked exactly as it shows in manual.

Worked perfect for my 2024 GMC Sierra! Cheap price!

Worked perfectly on the first try, in half a minute total. Impressive, especially since it is cheap. Clear instructions, well packaged.Now, why would you need a tool like this in the first place, that's on GM. Other American manufacturers (I'm thinking of the one everyone hates these days) didn't need one since the car learns the TPMS sensors and wheel positions automatically, you don't even have to do anything on the vehicle settings...Still, being able to buy this tool, for a very reasonable price, is a solution for the car manufacturer's disrespect of the customer in the design phase.

The tire shop rotated my tires on my 2016 GMC Sierra 2500HD but didn't resync the TPMS. Instead of wasting $12 in fuel and 2 hours of my time returning to the shop, I bought this tool. Resyncing was very easy using the instruction in my vehicle's owners manual. I tried several times placing the tool at the valve stem and it did not work. I then moved the tool to the tires rubber side near the valve stem instead of near the valve stem on the aluminum rim side. It then worked flawlessly. I suspect the signal from the tool is very weak and was blocked by the metal rim.

I was trying to avoid being overcharged by the auto shops to perform a very simple tire pressure monitoring system tire position re-learn, so when I saw this tool for $5, I thought what have I got to lose! Followed the included directions to a tee and the process could not have been quicker or smoother. I made sure by using my multimeter that the 9 volt battery (remember, battery is NOT included) I had was well over the 9 volt mark, as the instructions and other reviewers have indicated that it must be a new, fresh battery or the device won’t work. Pulled the car out of the garage and onto the driveway to avoid any radio frequency interferences, as is stated in the instruction manual. After placing my vehicle in the tire position re-learn mode, I started with the left front (driver’s side), then right front, followed by right rear and finally the left rear, each time touching the tool’s antenna onto each tire where the rim and tire meet, next to and parallel to each tire’s valve stem. Make sure to hold the white button on the tool down until you hear each tire make the horn blow indicating it has been accepted into the system. The entire procedure took less than 5 minutes. Well pleased!

Absolutely love it. Did the job first time through and no need to bring the car to a service center.

Worked great on my 2016 Cadillac Escalade. It was very easy and straightforward. Reset all the sensors to connect the one that dropped off and been good ever since.

This worked fine for my Chevy Tahoe. At first, I thought it did not work because I was holding the antenna next to the valve stem. It needs to be very close to the TPMS sensor. When I moved it right at the edge of the rim by the valve stem. It worked just fine. It’s possible this is not as powerful as some others. However this was definitely the right price.
