随着科技的快速发展,汽车发动机的控制技术也越来越复杂,这也为汽车故障诊断带来了极大挑战。为了能够快速、准确地寻找汽车故障位置,利用故障诊断仪,对汽车发动机的数据流进行检测分析,并与标准参考进行比对,从而判断故障发生的部位,促进汽车维修技术水平的提升。 With the rapid development of science and technology, the control technology of automobile engines is also more and more complicated, which also brings great challenges to the automobile fault diagnosis. In order to quickly and accurately find the location of the vehicle fault, the fault diagnosis instrument is used to detect and analyze the data flow of the engine of the automobile and compare it with the standard reference to determine the fault location and promote the improvement of the technical level of vehicle maintenance.
