Solution

1. Preparation

Gather necessary tools: OBD-II scanner, tire pressure gauge, and a digital multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Tire Pressure Check

Tools Required: Tire pressure gauge
Use the tire pressure gauge to measure the pressure in each tire.
Adjust the pressure in each tire to match the manufacturer's recommended settings (usually found on a sticker inside the driver's door).

3. TPMS Sensor Inspection

Tools Required: None
Visually inspect each tire for any physical damage to the tire pressure sensors.
Check for any corrosion on the sensor contacts and clean them if necessary.

4. Battery Replacement (if needed)

Tools Required: Tire iron and appropriate socket set
Remove the tire from the wheel hub using the tire iron.
Access the TPMS sensor located inside the tire and remove it.
Replace the battery in the sensor (if applicable) or replace the entire sensor if damaged.

5. System Reset

Tools Required: OBD-II scanner (if required)
Follow the manufacturer's instructions to reset the TPMS, either by pressing the reset button (usually located beneath the steering column) or using the vehicle's onboard diagnostics system via the OBD-II scanner.
Confirm that the TPMS light resets and stays off after the procedure.
