摘　　要：针对当前汽车自诊断系统所设置的故障码不能涵盖电控系统的全部故障的现状,通过采用专用故障诊断仪器读取数据流,能更准确、快速判断电控发动机故障点及故障原因。通过典型案例表明,通过对动态数值的分析,可以比单独利用故障码进行故障排除更加有效快捷。At present the automobile Self - diagnosis system＇ s fault codes can not cover the whole status of electronic control system .Through the special fault diagnosis instrument reads the data stream. The method can determine the fault point and reasons of electronic controlled engine accurately and quickly. The typical case shows that it is more effective and faster than simply using the fault code to eliminate fault .
