Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, jack, jack stands, and OBD-II scanner.
Park the vehicle on a level surface and engage the parking brake.

2. Check and Adjust Tire Pressure

Sub-steps:
- Remove the valve stem caps from all four tires.
- Use the tire pressure gauge to measure the pressure in each tire. Refer to the vehicle’s owner’s manual or the sticker on the driver’s side door jamb for the recommended pressure.
- If any tire is below the recommended pressure, add air using an air compressor until the proper pressure is achieved.
- If any tire is over-inflated, release some air until the correct pressure is reached.
- Replace the valve stem caps securely.

3. Inspect and Repair Tires (if necessary)

Sub-steps:
- If any tire shows signs of damage or punctures, inspect the area thoroughly.
- If a puncture is found, use a tire repair kit to patch it or take the tire to a professional for a proper repair.
- For tires with excessive wear, consider replacing them with new tires.

4. Reset TPMS

Sub-steps:
- Start the vehicle and locate the TPMS reset button (usually underneath the steering wheel or in the glove compartment).
- Press and hold the reset button until the TPMS light blinks three times and then release it.
- Drive the vehicle for a few minutes to allow the system to recalibrate.
