Solution

1. Preparation

Gather necessary tools including a tire pressure gauge, TPMS tool, and a diagnostic scanner.
Ensure the vehicle is parked on a level surface and the tires are cold (not driven for at least three hours).

2. Check Tire Pressure

Use the tire pressure gauge to measure the pressure in each tire.
Compare the readings with the recommended tire pressure found on the driver’s side door jamb.
Inflate or deflate tires as necessary to achieve the recommended pressures.

3. Inspect and Repair Tires

Visually inspect each tire for signs of damage or punctures.
If any damage is found, remove the tire and repair or replace it as necessary.
Ensure the valve stems are not leaking. Replace any faulty valve stems.

4. Reset the TPMS

Access the vehicle’s settings through the touchscreen.
Navigate to 'Service' > 'TPMS Reset' and follow the on-screen instructions to reset the TPMS.
Confirm that a confirmation message appears indicating that the reset was successful.

5. Update Software

Check for any available software updates under 'Software' in the vehicle settings.
If updates are available, follow the prompts to install the updates, as they may resolve sensor communication issues.

6. Re-Scan for Codes

After completing the above steps, use the diagnostic scanner to check the TPMS system for any error codes.
Clear any codes and monitor if the tire pressure warning light returns.
