Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, vehicle owner's manual
Ensure the vehicle is parked on a level surface and the tires are cold.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove valve caps from each tire.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Compare the readings to the recommended tire pressure found on the driver’s side door jamb.
4. Inflate or deflate tires accordingly to match the recommended pressure.
5. Replace valve caps securely.

3. Scan for Error Codes

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Turn the ignition to the "ON" position without starting the engine.
3. Follow the scanner’s prompts to read any TPMS-related error codes.
4. Record any codes for further analysis or repairs.

4. Reset the TPMS

Sub-steps:
1. With the vehicle in the "ON" position, navigate to the TPMS reset option in the vehicle settings menu.
2. Follow the prompts to reset the TPMS.
3. Confirm that the TPMS warning light turns off.
4. Drive the vehicle for a short distance to allow the system to recalibrate.
