Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor, OBD-II scanner, tire repair kit (if needed).
Park the vehicle on a flat surface and turn off the ignition.
Ensure the tires are cool for an accurate pressure reading.

2. Check and Inflate Tires

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Compare the readings to the recommended tire pressure listed on the driver’s side door jamb.
4. If any tire is below the recommended pressure, use the air compressor to inflate it to the correct level.
5. Replace the valve stem caps securely.

3. Inspect and Repair Tires (if necessary)

Sub-steps:
1. Visually inspect each tire for punctures or foreign objects.
2. If a puncture is found, use a tire repair kit to seal it as per the kit instructions.
3. If the damage is severe, remove the tire and replace it with a spare or new tire.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition key to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually beneath the steering column or near the driver's seat).
3. Press and hold the TPMS reset button until the tire pressure light blinks three times, then release the button.
4. Start the engine and allow the vehicle to run for a few minutes to complete the reset.

5. Final Check

Sub-steps:
1. Drive the vehicle for a short distance to ensure that the TPMS light remains off.
2. Recheck tire pressure after driving to confirm stability.
