OBD（On-Board Diagnostic）is a system for monitoring the working state of the car and report anomaly. At the beginning, it was used for monitoring the performance of engine to reduce emission. With the development of technology, nowadays OBD can report real-time data and standardized fault code, and it has made the car fault diagnosis repair methods totally changed.
