Modern cars are more or less computers on wheel. With automobiles developing one fault or the other while in use. There is an urgent corresponding demand for a more sophisticated automobile diagnostic tool. This project designed and implemented an on-board diagnostic reader which is equipped with the functionality scanning, diagnosing and correcting trouble codes. It was designed using LM327 and associated circuitry. It communicates with computerized components of an automobile. It displays scanned fault codes on a window based diagnostic application. This has been designed to work only with Toyota brand of automobile. Hence, it makes it unnecessary to employ the service of an auto technician.
