Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, jack, jack stands, wrench set, and a tire pressure monitoring system tool (if needed).
Ensure vehicle is parked on a level surface and the engine is off.

2. Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Inflate tires to the manufacturer-recommended pressure (usually found on a sticker inside the driver’s door frame).
3. Recheck pressure with the gauge after inflating and replace valve caps.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the wheel from the vehicle using a jack and jack stands.
2. Detach the tire from the rim using a tire mounting machine.
3. Carefully inspect the TPMS sensor; if damaged, replace it with a new sensor.
4. Reinstall the tire onto the rim and secure the wheel back onto the vehicle.

4. Reset TPMS System

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Locate the TPMS reset button (usually under the steering column) and hold it until the TPMS light blinks three times.
3. Start the engine and check if the light turns off.
