Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and an air compressor.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from each tire.
2. Measure the tire pressure with a tire pressure gauge.
3. Inflate or deflate each tire to the recommended pressure as specified in the owner’s manual or on the door placard.
4. Reinstall the valve caps securely.

3. Inspect and Repair Tires

Sub-steps:
1. Visually inspect each tire for signs of damage or wear.
2. If a puncture or significant damage is found, replace the tire or have it professionally repaired.
3. Check the tread depth to ensure it meets legal safety requirements.

4. Reset TPMS

Sub-steps:
1. Locate the TPMS reset button, usually found under the steering wheel or in the glove compartment.
2. Press and hold the TPMS reset button until the warning light blinks three times, then release it.
3. Start the vehicle and allow it to run for a few minutes to ensure the system recalibrates.

5. Final Checks

Sub-steps:
1. Re-check tire pressures after resetting the TPMS to confirm they remain correct.
2. Drive the vehicle for a short distance to monitor if the tire pressure light turns off.
