2010 model year vehicles are exempt from OBD inspection. OBD (On-Board Diagnostics) is an automotive self-diagnostic system with the following functions: 1. Locating and describing faults in specific components to facilitate repairs; 2. Alerting when faults cause excessive emissions, indicating increased environmental pollution. OBD systems include: 1. EGR; 2. Engine; 3. Particulate filter; 4. Catalytic converter; 5. Oxygen sensor; 6. Emission control system; 7. Fuel system. OBD working principle: When emission-related faults occur, the ECU records fault information and corresponding codes, then notifies the driver through illumination of the malfunction indicator lamp or check engine light.
