Solution

1. Preparation

Gather tools: Tire pressure gauge, OBD-II scanner (if needed), air compressor.
Ensure the vehicle is parked on a level surface and the tires are cool for accurate pressure readings.

2. Check and Adjust Tire Pressure

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 measured pressure with the recommended pressure.
4. If the pressure is low, use an air compressor to inflate the tire to the correct pressure.
5. Replace the valve stem caps securely after checking.

3. Inspect Tires for Damage

Sub-steps:
1. Visually inspect each tire for cuts, bulges, or punctures.
2. Check the tread depth using a tread depth gauge or the penny test.
3. If any damage is found, determine if the tire needs repair or replacement.

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 found under the steering wheel).
3. Press and hold the reset button until the tire pressure warning light blinks three times, then release.
4. Start the vehicle and check if the warning light remains off.
