当汽车电子元件出现故障进行检查时,最重要的是测量数据和故障原因的推理过程。因为电子元件内部的情况不像机械部件能拆开看见,而利用合理的逻辑步骤检测可很快发现问题,在这个过程中的关键工具就是万用表。一般的万用表只能测试电 When the car electronic components to check the failure, the most important thing is the reasoning of measurement data and failure reasons. Because internal electronics do not look like mechanical parts and can be quickly identified with sound logic steps, the key tool in the process is the multimeter. General multimeter can only test the electricity
