This is a tire pressure reset tool designed to assist in the sensor relearn procedure. After tire rotation, replacement of tires, body control module, or tire pressure sensors, the relearn process must be performed to ensure accurate tire pressure readings and display. Operation steps: 1. Ensure the vehicle is in TPMS learning mode. 2. Follow the vehicle manufacturer’s maintenance procedure. Position the tool near each tire’s sidewall close to the valve stem (air filling inlet) in sequence (front left, front right, rear right, rear left) and press the reset button. 3. The green LED (TX indicator) will illuminate, signaling transmission. When the vehicle’s horn or buzzer sounds, pairing is successful. 4. Repeat the process for remaining tires.
