Solution

1. Preparation

Gather necessary tools: OBD-II scanner, tire pressure gauge, TPMS reset tool (if needed).
Ensure the vehicle is parked on a level surface and the tires are cool to the touch.

2. Inspect Tire Pressure and Sensors

Using a tire pressure gauge, check the pressure of all tires and adjust them to the recommended PSI.
Visually inspect each tire for damage and check that the valve stems are not cracked or leaking.
If any tire sensor is damaged, replace it according to the manufacturer's specifications.

3. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port and retrieve any TPMS-related error codes.
Note the codes for reference and address any indicated issues.

4. Reset TPMS

Turn the ignition to the "ON" position without starting the engine.
Locate the TPMS reset button (usually under the steering wheel) and press and hold it until the TPMS light blinks three times, then release it.
Start the vehicle and check if the TPMS warning light turns off after driving for a short distance.

5. Replace TPMS Sensor (if necessary)

If a sensor is faulty, remove the tire from the wheel to access the sensor.
Detach the old sensor, ensuring to disconnect the battery before working on the sensors.
Install the new sensor following the manufacturer's guidelines, ensuring it is properly seated.
Reinstall the tire, inflate it to the correct pressure, and perform a TPMS reset again.
