EL-50448 TPMS Relearn Tool for Auto Tire Pressure Monitor System Sensor Activation TPMS Reset Tool OEC-T5 for Buick/Chevy/Cadillac Series Vehicles 2026 Edition

Worked on my 2020 Traverse. I was able to figure out why my TPMS alert was appearing. Its fast at finding the sensors in the tire and connects to it instantly. It doesn’t make noise. My car will beep the horn when it connects to each one. Just make sure you have a 9v battery as it does not come with one.

I recently purchased a reliable and essential tool for auto tire pressure monitoring system sensors. I was pleasantly surprised by some key features that make it stand out: Wide Vehicle Coverage: It works on most GM vehicles (Chevy, Buick, Opel, Cadillac, etc.) from 2006 to 2022, including cars, SUVs, and pickups. If your vehicle is equipped with a 315 or 433 MHz Tire Pressure Monitor System (TPMS) sensor, this tool has you covered. Easy to Use: Resetting all tires is a breeze with just three steps: Ensure your vehicle is in TPMS Learn Mode. Hold the tool against the sidewall of the tire near the valve stem. Depress the Learn button while holding the tool against the tire sidewall. Time and Money Saver: Forget about going to the dealer or a tire store to reset your pressure sensors. With the EL-50448, you can activate individual TPM sensors within 1-2 minutes, saving you both time and money. Energy-Saving and Upgraded: The 2023 edition of EL50448 is faster, stronger, and more sensitive than other TPMS relearn tools. Plus, it’s energy-saving, making it an efficient choice. Remember these friendly tips: Ensure the antenna is in the correct position when using EL50448. Check that the 9V battery is in good condition. Different vehicles may require varying times to reset all tire sensors after rotation. Enjoy hassle-free tire maintenance with the JDIAG EL-50448! 🚗🌟

Worked great. This is the perfect tool to reset the sensors when I rotate the tires. No need to go to the dealer or tire shop.

Used this to relearn TPMS sensors on a GM vehicle and it worked as intended after a couple of tries. Shipping was on time and the tool arrived well packaged. It looks just like the listing and feels lightweight but decent for a simple diagnostic tool. In terms of performance, it does the job. It successfully triggered the sensors and allowed the relearn process to complete. That said, it wasn’t completely smooth on the first attempt—I had to reposition it a couple of times and follow the sequence carefully. The instructions could be clearer, especially if you’re using it for the first time. Once you understand the process, it becomes much easier. Overall, it’s a practical tool to have if you work on your own vehicle and want to avoid going to a shop for TPMS resets. It works, just expect a small learning curve. 4 stars.

I wasn’t sure if it would work or not but for $7 it wasn’t really a huge risk to me. I replaced all the sensors in my tires and after putting the car in tpms relearn mode: Step 1: Locate the TPMS interface plug. This is a white female plug that is attached to the OBD II wire loom under the dash right about where your left knee would be when sitting in the driver's seat. You may have to cut the tape that is holding the TPMS interface plug to the OBD II wire loom. Step 2: Attach a paper clip or wire into the interface plug. Step 3: Put your key in the ignition and turn it to the last click before the engine starts. Or push the push start button twice. This is the KOEO position (Key On, Engine Off). Step 4: Tap the end of the paper clip or wire on any exposed ground (metal) 6 times within 10 seconds of turning ignition on. Make sure it is a real ground and not just any metal you find. Step 5: If you completed step 4 then the TPMS warning light will start to slowly flash and you have activated the TPMS relearn process. If it flashes fast that's not right. If yours isn't flashing slowly then check your connections, turn the ignition off and start over at step 3. Step 6: Once you confirm the light does not stop flashing, go around to each tire with the TPMS tool and hold the button for a few seconds. I didn’t get any sort of alarm or notification that the sensor had been programmed, I just held it at each tire while holding the button for approximately 5 seconds and then moved to the next tire. The lo and behold, TPMS light went away and all the new sensors have been programmed. Hopefully this helps!

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!

Works great use it at my tire shop, great price, easy to use.

It works perfectly fine but it doesn't activate off brand sensors. Example. A Chevy comes in and needs a new sensor. We put a universal tpms in like autel. Now this won't activate it. But if you're in a dealership where they most likely have manufacturer specific TPMS installed this is a must. I don't know about anyone else's experience in that

Buen precio y funcional. facil de usar calidad ,cumple para su proposito

This inexpensive unit worked on my gm oem sensors that I installed into my four travel trailer tires I originally started with the air pressure method, inflating or deflating the four tires. It was a painfully slow process trying to get the vehicle to recognize the sensors, and on top of that I had an unknown faulty sensor. The vehicle system timed out. I purchased the unit to make the deflate/inflate method a thing of the past. I got the sensors to be recognized by the vehicle system very quickly and It also determined one of the four sensors was faulty. This is what I needed from the start, no stress

Me funcionó muy bien en sistema de presión de neumáticos de Cadillac XTS

Bought this JDIAG EL-50448 TPMS Relearn Tool to use with new sensors on wheels for a 2015 Camaro. Had the sensors set up (relearned) in 2 minutes, worked flawlessly.

Sin problemas, programación adecuada.
