Solution

1. Preparation

Gather necessary tools (OBD-II scanner, tire pressure gauge, TPMS scanner).
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check Tire Pressures

Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate tires to the recommended pressure as stated on the driver's door jamb sticker.

3. Inspect Tires

Visually inspect each tire for damage, punctures, or uneven wear.
- If damage is found, replace the affected tire.

4. Reset TPMS

If tire pressures are correct and tires are undamaged, reset the TPMS:
- Use the vehicle's settings menu to find the TPMS reset option.
- Follow on-screen prompts to reset the system.
- Alternatively, if using a manual reset, turn the ignition to the "on" position (do not start the engine) and press the TPMS reset button (if equipped) until the light blinks and then turns off.

5. Verify Sensor Functionality

If the TPMS light remains on, use a TPMS scanner to check each sensor's signal.
- Replace any non-functioning sensors as necessary.

6. Final Check

After repairs, ensure that all tools are removed from the vehicle and that all tire pressures are verified again.
