When you need this tire relearn tool?
Do tire rotation, didn’t have a quick and easy way to let ECU relearn new tire information.
The TPMS needs to be reset after fixing problems such as low tire pressure or air leakage/replacement or installation of tire pressure monitoring equipment/replacement of tires, damaged sensors, etc.
A new TPMS sensor was installed, and neither the tire deflated nor the tire inflated would allow the system to recognize the new sensor.
When the tire pressure indicator lights up, after the repair is complete, the tire pressure needs to be reset to turn off the TPMS indicator.

Received tool with not instructions and had no luck with it resetting my tire pressure monitor system. Cheap junk. Don't buy. Wasted my money.

It relearned the TPMS sensor position for the new sensors I installed on my 2017 1500 Silverado. I had a little trouble initially. I thought I had installed a fresh 9 volt battery and my truck wasn't recognizing the sensors with this EL-50448. The green activity indicator lit when I pushed the button and immediately went out when I released it. The red, low battery indicator never came on. I tried everything I could think of and it refused to learn. I was about to return it and checked the battery with my meter before doing so which was 8.83 volts. So I swapped the battery from my meter into it, 9.32 volts. After that it worked like a charm. The green indicator is brighter and flashes for about five seconds after I release the button. Had I known that slight discrepancy about the indicators up front it would have been a little more obvious something was wrong. Bottom line, make sure you use a fresh battery in it.

It worked perfectly for me on the first try it used it several times and I keep it in my car now so I can use it any time I get my tires rotated. It was also much cheaper than other options from other merchants.

Comes without batteries and when I tested against the Tom’s did nothing other than beeping like if the was not sensor. What a waste of money
