Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety warning: Allow the vehicle to cool if tires have been driven recently to avoid burns.

2. Check and Adjust Tire Pressures

Tools Required: Tire pressure gauge, air compressor.
Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Inflate or deflate tires as necessary to match the recommended pressure (typically found on the door jamb).
4. Replace the valve stem caps securely after adjustment.

3. Inspect Tires for Damage

Tools Required: Visual inspection tools (flashlight).
Sub-steps:
1. Examine each tire carefully for any visible damage or foreign objects.
2. Check for uneven wear patterns which could suggest alignment or suspension issues.
3. If damage is found, consider replacing the affected tire(s).

4. Reset TPMS

Tools Required: OBD-II scanner (if necessary).
Sub-steps:
1. Follow the owner's manual to reset the TPMS; typically involves turning the ignition to the “ON” position without starting the engine and pressing the TPMS reset button.
2. For vehicles without a reset button, use the OBD-II scanner to reset the TPMS system.
3. Confirm the TPMS light turns off after resetting.
