Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, air compressor, tire repair kit (if needed).
Ensure the vehicle is parked on a level surface.
Allow the vehicle to cool down if it has been driven recently.

2. Check and Adjust Tire Pressure

Remove the valve caps from each tire.
Use a tire pressure gauge to measure the pressure of each tire.
Compare the measured pressure with the recommended pressure (usually found on the driver’s side door jamb).
Inflate any tires that are below the recommended pressure using an air compressor until they are at the appropriate level.
Replace the valve caps securely.

3. Inspect Tires

Visually inspect each tire for signs of damage, such as cuts, bulges, or punctures.
If any damage is found, use a tire repair kit to patch minor punctures or take the vehicle to a tire shop for professional repair or replacement if necessary.

4. Reset TPMS (if needed)

Turn the ignition key to the "On" position without starting the engine.
Locate the TPMS reset button (usually under the steering column or in the glove compartment).
Press and hold the TPMS reset button until the TPMS light blinks three times.
Start the engine and drive the vehicle for about 10 minutes to allow the system to recalibrate.
