Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, socket set, and a torque wrench.
Ensure the vehicle is parked on a level surface and the tires are cool.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires as needed to reach the manufacturer-recommended pressure (found on the driver’s side door jamb).
4. Replace valve caps securely.

3. Reset TPMS

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually beneath the steering column).
3. Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
4. Start the vehicle and check that the TPMS light is off.

4. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Lift the vehicle and remove the wheels.
2. Use a socket set to remove the valve stem nuts securing the TPMS sensors.
3. Inspect sensors for corrosion or damage; replace if necessary.
4. Install new sensors and torque the valve stem nuts to the manufacturer's specification.
5. Reinstall the wheels and lower the vehicle.
