Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, OBD-II scanner (optional)
Ensure the vehicle is parked on a level surface and has been stationary for at least 30 minutes for accurate tire pressure readings.

2. Inflate Tires

Use a tire pressure gauge to check the pressure of each tire.
Inflate any tire that is below the manufacturer's recommended pressure (usually found on the driver’s door jamb).
- Sub-steps:
  - Remove the valve stem cap.
  - Attach the air compressor nozzle to the valve stem and add air until the recommended pressure is reached.
  - Recheck the pressure with the gauge to ensure accuracy.
  - Replace the valve stem cap securely.

3. Inspect and Repair

If a tire is damaged (punctured or has sidewall issues), proceed with repair or replacement.
- Sub-steps:
  - Remove the tire from the vehicle using a socket set.
  - Inspect the interior and exterior for punctures.
  - If repairable, use a tire plug kit to seal the puncture or take it to a professional for patching.
  - If the tire is irreparable, replace it with a new tire.

4. Reset TPMS

After addressing any low pressure issues, reset the TPMS.
- Sub-steps:
  - Go to the vehicle’s center display.
  - Navigate to the ‘Service’ menu and select ‘Tire Pressure Monitoring.’
  - Follow the instructions to reset the TPMS.
