How does a vehicle diagnostic application work?
Vehicle diagnostic applications work primarily by connecting the OBD-II system (On-Board Diagnostics) of your car with your mobile phone or tablet. This system is a standard port on most vehicles manufactured since 1996 and allows data related to engine performance and other vital car systems to be transmitted.
To use these applications, you need a OBD-II adapter, which connects to the vehicle's diagnostic port. This adapter then connects to your phone via Bluetooth or Wi-Fi, which allows the app to receive the car data. The app then interprets the data and provides you error codes, diagnostic reports, and even tips for fixing common problems.
