Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface.
Turn off the ignition and disconnect the battery for safety.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure of all tires.
Inflate or deflate tires to the recommended pressure specified on the driver’s door jamb sticker.

3. Inspect and Replace TPMS Sensors

Remove the tire from the wheel using a tire changing machine.
Carefully detach the TPMS sensor from the valve stem.
Inspect the sensor for damage; if damaged, replace it with a new sensor.
If the sensor is functional, verify its battery life; replace if necessary.

4. Reinstall Tires

Reattach the TPMS sensor to the valve stem.
Mount the tire back onto the wheel and balance it if required.
Reinstall the tire on the vehicle.

5. Reset TPMS

Reconnect the battery.
Follow the manufacturer’s procedure to reset the TPMS, which may involve turning the ignition on and off or pressing a reset button.

6. Final Inspection

After resetting, check for any error codes using the OBD-II scanner.
Ensure the TPMS warning light is no longer illuminated.
