Solution

1. Preparation

Gather tools and materials needed: tire pressure gauge, air compressor, OBD-II scanner (if applicable).
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to check the pressure in each tire.
3. Refer to the vehicle’s door jamb or owner’s manual for the recommended tire pressure.
4. If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
5. Reinstall the valve stem caps securely.

3. Inspect and Repair Tires

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or other signs of damage.
2. If damage is found, repair the tire using a tire repair kit or take it to a professional for a proper repair.
3. Ensure all tires are in good condition and not excessively worn.

4. Reset TPMS

Sub-steps:
1. Turn the ignition to the "ON" position (do not start the engine).
2. Locate the TPMS reset button (usually found under the steering wheel or in the glove compartment).
3. Press and hold the reset button until the TPMS light blinks three times, then release it.
4. Start the vehicle and check if the warning light goes off.
