Solution

1. Preparation

Gather necessary tools: OBD-II scanner (if needed), tire pressure gauge.
Ensure the vehicle is parked on a level surface.
Turn the ignition to the "On" position without starting the engine.

2. Check and Adjust Tire Pressures

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires as necessary to match the recommended PSI found on the driver's door jamb sticker.
Wait a few minutes after adjusting to ensure the TPMS registers the new pressures.

3. Reset the TPMS

Using the TPMS Reset Procedure:
- Turn the ignition to "On" (engine off).
- Press and hold the TPMS reset button, typically located under the steering column or in the glove box, until the TPMS light blinks three times and then turns off.
- Release the button and turn the ignition off.
- Start the vehicle and verify that the tire pressure light remains off.

4. Recheck Tire Pressures

After resetting, use the tire pressure gauge again to ensure all tires are still at the correct pressure.
Drive the vehicle for a short distance (about 10-15 minutes) to allow the TPMS to recalibrate.
