随着科学技术的进步,现代汽车电控系统日趋复杂,对汽车维修技术人员的要求越来越高。为使汽车不致因为电子控制系统自身的突发故障导致汽车失控或不能运行,设计人员在进行汽车电子控制系统设计的同时增加了故障自诊断功能模块,它能够在汽车运行过程中不断监测电子控制系统各组成部分的工作情况,如有异常,根据特定的算法判断出具体的故障,并以代码形式存储下来。在维修电控发动机过程中,用故障诊断仪读取电控发动机运行中的数据流,并对测量出来的数据和标准数据进行对比分析,可以快速、准确地找出故障的原因和故障的部位,大大地提高了维修的工作效率。
With the advancement of science and technology, the modern car electronic control system is becoming more and more complicated, and the requirements for the car maintenance technicians are getting higher and higher. In order to prevent the car from running out of control or unable to run due to the sudden failure of the electronic control system, the designer adds the self-diagnosis function module of the fault while designing the electronic control system of the automobile and can continuously monitor the electronic control System components of the work, if any, according to specific algorithms to determine the specific failure, and stored in the form of code. In the process of repairing the electronically controlled engine, the fault diagnosis meter reads the data flow in the operation of the electronically controlled engine and compares the measured data with the standard data to quickly and accurately find out the cause of the fault and the location of the fault , Greatly improving the efficiency of maintenance work.
