With the continuous development and progress of the automobile industry in the world, computer technology and microelectronic technology are increasingly being applied to automotive products. The automotive technology is becoming more and more intelligent. The function of memory and storage of automotive faults is becoming more sophisticated. Using the decoder to read the fault code, analyze the data stream, and detect the electrical control signal waveform is a very important way to troubleshoot the electronic control vehicle. 1. Data flow analysis of the application data flow is the ECU control of the system status of the number of forms of performance control. Data flow analysis is the process of comprehensively analyzing all kinds of relevant data of the control system by using various testing methods and is a basic measure for fault diagnosis of modern vehicle maintenance. data
