Solution

1. Preparation

Gather necessary tools: OBD-II scanner, tire pressure gauge, jack, and jack stands.
Ensure the vehicle is parked on a flat, stable surface and the engine is off.

2. Inspect and Inflate Tires

Use a tire pressure gauge to check the current pressure in all tires.
Inflate each tire to the manufacturer’s recommended pressure (usually found on the driver’s side door jamb).
Replace any damaged or punctured tires if necessary.

3. Reset the TPMS

Turn the ignition to the "ON" position without starting the engine.
Locate the TPMS reset button (usually found under the steering column or on the dashboard).
Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
Start the engine and let it run for a few minutes to allow the system to recalibrate.

4. Replace TPMS Sensors (if necessary)

If the TPMS sensors are faulty, remove the tire from the wheel using a tire changer.
Use a TPMS sensor tool to remove the old sensor from the valve stem.
Install a new TPMS sensor according to the manufacturer’s instructions.
Reassemble the tire onto the wheel and balance it as necessary.

5. Recheck System Functionality

After reinstallation, use an OBD-II scanner to check for any remaining error codes.
Clear any codes if necessary and ensure the TPMS light is off after the reset.
