5. Operating Instructions
This section outlines the procedure for using the aqxreight TPMS Reset Tool to relearn tire pressure sensors.
- Prepare Vehicle: Ensure the vehicle is in TPMS learning mode. Refer to your vehicle's owner's manual for specific instructions on how to enter this mode. Typically, the car horns will chirp twice to confirm entry into learning mode.
- Position Tool: Starting from the left front tire, hold the tool's antenna against the tire sidewall, near the valve stem. The antenna should be facing upwards.
- Activate Sensor: Depress the activation button on the tool while holding it against the tire sidewall. Wait for the tool to emit a chirp. Once the chirp is heard, the sensor information is read. The vehicle's turn signal light for that corner should illuminate, indicating successful activation.
- Follow Sequence: Proceed to activate the remaining sensors in the following order: Front Left, Front Right, Rear Right, Rear Left.
- Complete Relearn: After all sensors have been reset, the car horns will chirp twice, signifying that the TPMS relearn process is complete.
