Solution

1. Preparation

Gather tools: Tire pressure gauge, air compressor, OBD-II scanner (if needed), and a jack (if tire inspection is required).
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inflate Tires

Using the tire pressure gauge, measure the pressure in each tire.
If any tire is below the recommended pressure, use an air compressor to inflate the tire to the correct specification.
Recheck the pressure after inflating to ensure it is accurate.

3. Inspect Tires

Visually inspect each tire for any damage, such as cuts, punctures, or bulges.
If any damage is found, remove the tire and repair or replace as necessary.

4. Reset TPMS (if necessary)

If the tire pressures are correct and the light remains illuminated, the TPMS may need to be reset.
Follow the manufacturer's instructions to reset the TPMS through the vehicle's settings menu or by using an OBD-II scanner.

5. Recheck

After any adjustments, take the vehicle for a short drive to allow the TPMS to recalibrate and ensure the warning light turns off.
