Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and a jack if needed.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Remove valve caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires as needed to match the manufacturer’s recommended pressure, typically found on the driver’s door jamb.
Replace the valve caps securely after adjusting.

3. Inspect and Replace TPMS Sensors (if necessary)

If any sensors are damaged, raise the vehicle with a jack and remove the tires.
Locate the TPMS sensor on the inner part of the tire (usually attached to the valve stem).
Disconnect the sensor from the valve stem and install a new sensor if needed.
Reinstall the tire and lower the vehicle back to the ground.

4. Reset the TPMS

Start the vehicle and ensure all tires are at the correct pressure.
Use the OBD-II scanner to reset the TPMS, or follow the manufacturer’s instructions for manual reset (usually involves a button in the vehicle).
Monitor the dashboard to verify that the tire pressure warning light has turned off.
