Solution

1. Preparation

Gather the necessary tools: tire pressure gauge, OBD-II scanner, TPMS reset tool (if applicable), and jack.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire, including the spare if applicable.
Inflate or deflate each tire to match the manufacturer's recommended pressure (usually found on the driver’s side door jamb).

3. Inspect and Repair Tires

Visually inspect each tire for cuts, punctures, or foreign objects embedded in the tread.
If damage is found, either repair the tire using a tire plug kit or replace the tire if damage is severe.

4. Inspect TPMS Sensors

If the tires are in good condition, locate the TPMS sensors on each wheel (typically mounted on the valve stem).
Check for corrosion or loose connections; clean any debris or rust that may affect sensor functionality.

5. Reset TPMS

If no issues are found with tire pressure and sensors, reset the TPMS:
- Turn the ignition to the ON position without starting the engine.
- Press the TPMS reset button (if equipped) until the light blinks three times, then release it.
- Drive the vehicle at speeds above 50 mph for about 10 minutes to complete the reset.
