摘 要: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。

Abstract: 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.

前言
仪表盘内的基本的故障指示灯包括发动机故障灯、电瓶灯、机油警报灯、水温警报灯以及胎压警报灯等。其中发动机配件里面有几十个不同的传感器,而不管其中哪一个传感器发生故障都会引起发动机故障灯点亮;电瓶灯点亮是由于汽车的点亮将要耗光或者发电机出现故障;机油警报灯点亮是由于机油缺少;水温警报灯点亮是由于发动机过热,应该立即停车熄火,等发动机冷却下来之后再重新启动;胎压警报灯点亮一般是由于轮胎亏气或者出现了扎胎的情况。以上是警报灯亮的原因,因此,在以后驾驶的过程中,应当及时注意警报灯的提醒,能够及时做出防范措施。……
