Solution

1. Preparation

Gather tools: Tire pressure gauge, OBD-II scanner, air compressor, and TPMS reset tool (if required).
Ensure the vehicle is parked on a level surface and the tires are cold 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 tire pressure for each tire.
3. Compare readings to the manufacturer's recommended tire pressure (usually found on the driver's door jamb).
4. Inflate tires to the recommended pressure using an air compressor if necessary.
5. Replace the valve stem caps securely.

3. Inspect Tires for Damage

Sub-steps:
1. Conduct a visual inspection of each tire for any signs of damage or wear.
2. Check the tread depth using a tread depth gauge to ensure tires are not worn beyond safe limits.
3. If damage is found, consider replacing the affected tire(s) or having them repaired.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "ON" position without starting 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 allow it to run for a few minutes to complete the reset process.
