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 2026 Edition

I have had to "relearn" the TPMS system on a older HHR after I rotated the tires and it was time consuming due to having to deflate and reinflate the tires to tell the system which corner the tire is on. This device simplified that immensely! The entire relearn process took about 3 minutes using this tool. Nice price too!

It looks nice. I've tried this on 3 gm rigs I've owned over the past cpl years... It hasn't been able to trigger the sensors in any.

It works well on my 2023 Chevy bolt EV. One thing to note is that the 9V battery has to be in excellent condition or the TPMS sensor will not recalibrate.

I purchased this tool to “wake up” aftermarket Dill internal TPMS sensor (1606-B). Open the Dill app, point the tool, close to the tire, depress and hold the button until it registers a reading. I first tried a new alkaline 9 V battery with mixed results. Switched to a Lithium 9 V and it works excellent. The battery cost more than the tool, worth the investment.

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! 🚗🌟

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!

This item allowed me to reprogram my 2015 Camaro rims TPMS installed in my 2014 Equinox. Took me 10 minutes once I entered the programming mode on Equinox. First fill tires to oem psi, enter programming mode, start at drive front, hold programmer near valve stem, horn will beep once it registers the sensor, continue to passenger front, passenger rear, then driver rear, on the last one horn will beep once registered, and then with a light delay beeps twice the the relearning process is complete. Pretty simple compared to the other methods. This item worked great and was at a really great price!

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.

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

Easy to use

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

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

This wouldn’t work with a brand new heavy duty 9v battery but worked perfectly fine with a new alkaline battery 🔋 👍🏼 Used it many times now. It’s cool 😎. Always makes me smile when the horn honks during use. Thanks ☺️
