What It Is / How It Works

This is a TPMS relearn tool, a handheld device that helps you reset the tire pressure monitoring system after installing new sensors, rotating tires, or when the TPMS light stays on. It works with 315MHz or 433MHz systems and is designed for most vehicles equipped with TPMS.

Who It's For / Use Cases

This tool is for car owners and DIYers who want to reset their TPMS after changing tires or sensors without a trip to the shop. It's also handy for mechanics who service multiple vehicles with TPMS.

How to Use / Care

1. Insert a 9V battery (not included) into the tool.
2. Put the car into TPMS learning mode (the horn will sound twice).
3. Starting at the left front tire, hold the tool's antenna against the tire sidewall near the valve stem, then press and release the button. Wait for the speaker to chirp, which confirms the sensor was read.
4. Repeat for the front right, rear right, and rear left tires in that order. When all sensors are reset, the horn will sound twice to confirm the relearn is complete.

How to Choose

When choosing a TPMS relearn tool, check that it supports the frequency your vehicle uses (315MHz or 433MHz) and that it is compatible with your car's TPMS system. Consider the tool's ease of use, such as clear audio or visual feedback, and whether it requires batteries that you need to supply.
