上汽大众途观仪表板上多个故障灯间歇性点亮故障思考

Reflections on intermittent lighting of multiple fault lights on SAIC Volkswagen's dashboard dashboard

在正常情况下,汽车仪表盘内的故障警报指示灯是不亮的,有些车主对于仪表盘内的各个警报指示灯也都不熟悉,在警报指示灯亮的时候会手足无措。文章主要根据上汽大众途观车总线故障引起的故障灯点亮的案例,通过分析故障灯点亮的基本原理,来缩小故障发生的原因范围。在我们对该车进行故障分析时,需要了解相关的关于汽车的故障知识,了解汽车的相关配件以及系统的功能和能够引发的故障类型,在充分了解之后,我们才能够在第一时间对该车故障发生的原因有一个初步的了解以及大体的诊断范围,才能够及时有效的对故障进行处理。

under normal circumstances,the fault warning lights in the vehicle instrument panel are not bright,and some owners are not familiar with the various warning signs in the instrument panel,and they are at a loss when the warning lights are lit.This paper is mainly based on the case of the fault lights on the bus fault of the SAIC Volkswagen bus.Through the analysis of the basic principle of the fault light,the cause of the fault is reduced.When we analyze the car for failure,we need to know the relevant knowledge about the fault of the car,understand the related parts of the car and the function of the system and the type of failure that can be caused.After the full understanding,we can have a preliminary understanding of the original cause of the car failure and the general reason for the first time.The scope of diagnosis can be used to deal with faults in time and effectively.
