Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and a TPMS reset tool if required.
Ensure you are working in a safe environment, preferably on a flat surface.

2. Check Tire Pressures

Sub-steps:
1. Remove valve caps from the tires.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Compare readings with the manufacturer’s recommended tire pressures (found on the driver's side door jamb).
4. Inflate or deflate tires as necessary to reach the recommended specifications.

3. Inspect Tires

Sub-steps:
1. Visually examine each tire for visible damage, such as cuts, punctures, or excessive wear.
2. Check the sidewalls for bulges or cracks.
3. Replace any damaged tires as needed.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "On" position (do not start the engine).
2. Locate the TPMS reset button (typically under the steering wheel or in the glove box).
3. Press and hold the reset button until the TPMS light blinks three times, then release it.
4. Start the engine and allow the vehicle to run for a few minutes to see if the light turns off.

5. Replace TPMS Sensor (if necessary)

Sub-steps:
1. If the TPMS light remains on, use an OBD-II scanner to check for specific sensor faults.
2. Remove the tire from the wheel to access the TPMS sensor.
3. Replace the faulty TPMS sensor with a new one (ensure it is compatible with the Mustang S650).
4. Reinstall the tire and ensure it is properly balanced.
