Solution

1. Preparation

Gather necessary tools including a tire pressure gauge, OBD-II scanner, and a TPMS reset tool (if needed).
Ensure all tires are properly inflated to the specified pressure.

2. Check and Inflate Tires

Using a tire pressure gauge, measure the pressure in each tire.
Inflate or deflate each tire as necessary to match the recommended tire pressure found on the driver’s side door jamb sticker.

3. Reset TPMS

Using the TPMS Reset Button:
- Turn the ignition to the "ON" position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering column or near the dash.
- Press and hold the reset button until the TPMS light blinks three times, then release it.
- Start the vehicle and let it run for about 20 minutes to allow the system to recalibrate.
Using an OBD-II Scanner:
- Connect the OBD-II scanner to the vehicle’s diagnostic port.
- Navigate to the TPMS section and select the reset function. Follow the on-screen instructions to reset the TPMS.

4. Final Check

After resetting, monitor the TPMS warning light. If it remains lit, there may be a malfunction in one of the sensors or the system itself.
Drive the vehicle for a short distance to allow the TPMS to recheck the tire pressures.
