【Abstract】Aiming at the problem that two or more driving cycles are required for emission-related network DTC confirmation，a semi-automated test method based on Vehicle Spy is proposed，which abandons complex hardware test system design，saves cost，and ensures the accuracy of test results. It lays a foundation for the design evaluation，problem analysis and logic testing of emission-related network DTC in the future.
