Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and air compressor.
Ensure the vehicle is parked on a flat surface and the tires are cool for accurate pressure readings.

2. Check and Adjust Tire Pressures

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the current pressure of each tire.
Refer to the vehicle's owner manual or the tire placard for the recommended tire pressure.
If any tire is below the recommended pressure, use an air compressor to inflate it to the specified level.
Recheck the pressure after inflating to ensure it is accurate.
Replace the valve caps securely.

3. Inspect and Replace Damaged Tires (if necessary)

If any tire shows signs of damage, remove it using a jack and jack stands.
Loosen and remove the lug nuts using a socket wrench.
Inspect the tire for punctures or damage; if found, consider replacing the tire.
Install the new tire by aligning it with the wheel hub and hand-tightening the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.

4. Reset the TPMS

Turn the ignition key to the "ON" position without starting the engine.
Locate the TPMS reset button (refer to the owner’s manual for specific location).
Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it.
Start the vehicle and check if the tire pressure light turns off after a few minutes of driving.
