Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, tire inflator, jack and jack stands (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Inflate Tires

Sub-steps:
1. Use the tire pressure gauge to measure the pressure in each tire.
2. Refer to the vehicle's door jamb or owner’s manual for the correct tire pressure specifications.
3. Inflate any tires that are below the recommended pressure using a tire inflator.
4. Recheck the tire pressure to confirm they are set correctly.

3. Reset TPMS

Sub-steps:
1. Turn on the vehicle without starting the engine.
2. Locate the TPMS reset button (usually under the dashboard) and press it until the TPMS light blinks three times.
3. Drive the vehicle for about 10-15 minutes at speeds over 50 mph to allow the system to recalibrate.

4. Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the light remains on, remove the tires from the wheels using a tire changing machine.
2. Replace the TPMS sensors located inside the tire on the wheel rim.
3. Reinstall the tires and ensure they are properly balanced and mounted.

5. Recheck System Functionality

Sub-steps:
1. Start the vehicle and check if the TPMS light has turned off.
2. Drive the vehicle for a short distance to verify the system is functioning properly.
