Solution

1. Preparation

Gather the following tools: tire pressure gauge, air compressor (if needed), and OBD-II scanner (if required).
Ensure all tires are at the recommended pressure levels as specified on the driver's door jamb.

2. Adjust Tire Pressures

Remove the valve caps from each tire.
Use the tire pressure gauge to check the pressure of each tire.
Inflate or deflate each tire as necessary to match the recommended pressure.
Reinstall the valve caps securely.

3. Reset the Tire Pressure Monitoring System (TPMS)

Start the vehicle and ensure it is in the "Run" position.
Press and hold the TPMS reset button, usually located under the steering wheel or near the dashboard, until the TPMS light blinks three times.
Release the button and allow the vehicle to run for about 20 minutes to confirm the system has reset.

4. Verify TPMS Reset (if necessary)

If the TPMS light remains on, use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) related to the TPMS system and follow appropriate procedures to resolve any issues.
