The invention relates to a fault recorder starting performance testing method and system. A testing module controls the constant value written in a fault recorder through the communication between a simulated master station and the fault recorder, a tester client loads a tester channel relevant document to establish the association relationship between the tester and the fault recorder, then the tester client simulates the fault, the simulated master station reads the wave recording document of the fault recorder, and the testing module analyzes the final test result by checking relevant information of the wave recording document. By employing the fault recorder starting performance testing method, the testing time can be effectively saved, and the testing quality and efficiency are improved.
