Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the tires are cold.
Tools Required: Tire pressure gauge, OBD-II scanner, socket set.

2. Adjust Tire Pressures

Sub-steps:
1. Use the tire pressure gauge to measure the pressure of each tire.
2. Inflate or deflate the tires to match the recommended pressure found on the driver’s door jamb sticker.
3. Recheck pressures to confirm they are accurate.

3. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Press the TPMS reset button, usually located beneath the steering column or in the glove box.
3. Hold the button until you see the TPMS light blink three times, then release it.
4. Start the engine and let it run for a few minutes to complete the reset process.

4. Replace TPMS Sensors (if faulty)

Sub-steps:
1. Remove the wheel from the vehicle using the appropriate socket.
2. Unscrew the valve stem cap and remove the TPMS sensor from the tire.
3. Install the new TPMS sensor according to the manufacturer's instructions.
4. Reinstall the wheel, ensuring that lug nuts are tightened to the specified torque.
