What is the use of the car OBD interface? There is a fault indicator light on the vehicle. By connecting the OBD interface to the computer, technicians can know the vehicle's fault code, then determine where the vehicle problem lies and perform repairs. OBD, in English, is the abbreviation of OnBoardDiagnostics, and in Chinese it means on-board automatic diagnostic system. As can be seen from the name, this function can diagnose the status of the vehicle. Read the fault code through the car's OBD interface, then analyze and clear the car's fault code. Just imagine, without this function, just relying on manpower to check vehicle faults would be very labor-intensive and materially resource-intensive. However, maintenance personnel can read the fault code through the original vehicle manufacturer's special instrument, quickly locate the fault, facilitate vehicle maintenance, and greatly reduce the time of manual diagnosis. To put it bluntly, by connecting to the OBD interface, you can view car data and detect car faults in real time, which provides convenience for car maintenance, car-related function development, and car equipment modification. OBD real-time monitoring includes EGR, engine, particulate trap, catalytic converter, oxygen sensor, emission control system, fuel system and other systems and components. Such as intake manifold pressure, intake air temperature, air flow, throttle position, oxygen sensor voltage, fuel pressure, etc.
