Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack, jack stands, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles as needed.

2. Inspect and Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from all four tires.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. If any tire is below the recommended pressure, inflate it to the specified PSI indicated in the owner’s manual or on the door jamb.
4. If any tire is overinflated, release air until the pressure matches the recommended level.
5. Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if needed)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to gain access to the TPMS sensors.
3. Visually inspect each sensor for damage; if damaged, use a wrench to remove the sensor nut and replace the sensor.
4. Install the new sensor, ensuring it is seated properly, and torque to manufacturer specifications (generally around 4-6 ft-lbs).
5. Reinstall the wheels and lower the vehicle.

4. Reset the TPMS System

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button, usually located beneath the steering wheel or in the glove compartment.
3. Press and hold the reset button until the TPMS light blinks three times, then release it.
4. Start the engine and allow it to run for a few minutes to ensure the system is reset.
