Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, jack, jack stands, tire repair kit (if needed), torque wrench.
Safety Warning: Ensure the vehicle is on a stable surface and the parking brake is engaged before lifting.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to measure the air pressure in each tire.
3. Inflate or deflate each tire to the manufacturer's recommended pressure (found on the driver’s door jamb).
4. Reinstall valve caps securely.

3. Inspect and Replace Tires if Necessary

Sub-steps:
1. If any tire is found to be damaged or excessively worn, mark it for replacement.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel lug nuts using a socket set and take off the wheel.
4. Replace the tire with a new or repaired tire, ensuring the TPMS sensor is intact and properly seated.
5. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

4. Reset TPMS System

Sub-steps:
1. With the vehicle running, navigate to the TPMS reset option on the vehicle’s dashboard menu.
2. Follow the prompts to reset the TPMS system.
3. Turn off the ignition and restart the vehicle to check if the alert has cleared.

5. Recheck and Verify Sensor Functionality

Sub-steps:
1. Use the OBD-II scanner to check if the TPMS sensors are functioning correctly.
2. If a sensor is not transmitting data, consider replacing the faulty TPMS sensor.
