Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, TPMS tool, jack, jack stands, and wheel chocks.
Safety Warnings: Ensure the vehicle is parked on a flat surface and the engine is off. Use wheel chocks to prevent movement.

2. Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from each tire.
2. Inflate or deflate each tire to the recommended PSI as found on the driver’s door jamb sticker or owner's manual.
3. Replace valve caps securely after adjusting the pressures.

3. Reset TPMS

Sub-steps:
1. Turn the ignition to the ON position (do not start the engine).
2. Locate the TPMS reset button (typically beneath the steering wheel).
3. Press and hold the TPMS reset button until the TPMS light blinks three times and then turns off.
4. Start the engine and drive the vehicle at speeds above 30 mph for 10 minutes to finalize the reset.

4. Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tire from the wheel using a tire changer.
2. Unscrew the TPMS sensor from the valve stem.
3. Install the new TPMS sensor and tighten it to the manufacturer's specifications (typically 3-4 Nm).
4. Reinstall the tire on the wheel and balance if necessary.
