Solution

1. Preparation

Gather all necessary tools and equipment.
Ensure the vehicle is parked on a level surface.
Ensure the tires are cool before measuring tire pressure.

2. Check and Inflate Tires

Sub-steps:
1. Remove the valve caps from each tire.
2. Use a tire pressure gauge to check the current pressure of each tire.
3. Inflate any tire that is below the recommended pressure (found on the driver’s side door jamb) to the correct PSI.
4. After inflating, replace the valve caps securely.

3. Inspect TPMS Sensors

Sub-steps:
1. If any tire is found to be damaged or punctured, replace or repair the tire as necessary.
2. If the tire pressure is correct but the warning light remains on, inspect the TPMS sensors for damage.
3. Remove the tire and check the sensor located inside the tire on the valve stem.
4. Replace any defective TPMS sensors with new ones, ensuring they are properly calibrated to the system.

4. Reset the TPMS System

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Press and hold the TPMS reset button (usually located under the steering wheel) until the TPMS light blinks three times.
3. Start the vehicle and allow it to run for a few minutes to ensure the system resets.
4. Confirm the tire pressure warning light is off.
