How does a car fault code reader work?
A car fault code reader, also known as a diagnostic tool, connects to your car's OBD-II port to sense and read any fault codes that have been registered by the vehicle's system. These fault codes indicate potential problems that need to be addressed to ensure smooth and efficient operation of your car.
