Solution

1. Preparation

Gather tools: Tire pressure gauge, OBD-II scanner, and tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cool to the touch.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from all tires.
2. Use the tire pressure gauge to measure the PSI of each tire.
3. Inflate or deflate tires as needed to reach the manufacturer's recommended pressure (found on the driver’s door jamb).
4. Replace valve caps securely.

3. Inspect Tires

Sub-steps:
1. Visually inspect all tires for cuts, punctures, or bubbles.
2. Check tread depth using a tread depth gauge; replace tires if tread is below 2/32 of an inch.
3. If any damage is found, plan to replace the tire accordingly.

4. Reset TPMS

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually beneath the steering column).
3. Press and hold the reset button until the TPMS light blinks three times, then release.
4. Start the engine and allow the system to recalibrate.

5. Check TPMS Sensors

Sub-steps:
1. Remove the tire from the rim if necessary to access the TPMS sensor.
2. Inspect the sensor for corrosion or physical damage.
3. Replace the TPMS sensor if necessary (consider using OEM parts).
4. Reinstall the tire and ensure it is properly balanced.
