Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, tire repair kit (if needed), and OBD-II scanner.
Ensure the vehicle is parked on a level surface and turn off the engine.

2. Check and Adjust Tire Pressures

Remove valve caps from each tire.
Use the tire pressure gauge to measure the pressure of each tire.
If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
If any tire is over-inflated, release pressure using the gauge until it reaches the recommended level.
Replace all valve caps securely after adjustment.

3. Inspect Tires

Visually inspect each tire for damage, such as cuts, bulges, or embedded objects.
If a tire is damaged or excessively worn, remove it and inspect the interior for punctures.
Repair small punctures using a tire repair kit or replace the tire if necessary.

4. Reset TPMS

Turn on the ignition without starting the engine.
Navigate to the vehicle settings on the dashboard display.
Locate the 'TPMS' or 'Tire Pressure' section and select the option to reset the system.
Confirm the reset and wait for the system to recalibrate.
