On the Application of Fault Code and Data Stream Analysis in Automobile Maintenance

Yu Xiaoxi

Abstract：With the development of domestic productivity， the automobile manufacturing industry is constantly prospering and growing. The proportion of people who own cars has increased significantly， and most consumer groups also have high requirements for the technology and quality of cars. To meet the needs of these consumers， automobile manufacturers are committed to effectively judging， detecting and solving a series of possible faults in production accurately and in a timely manner. The use of fault codes and data stream technology analysis is the key to detecting and solving fault problems. Fault code and data flow analysis can provide maintenance personnel with accurate directions for accurately detecting and solving fault problems， and can prevent maintenance personnel from taking detours in the process of vehicle maintenance.

Key words：fault code， data stream， automobile fault diagnosis

1 引言

汽车生产制造行业为了迎合消费者，在不断利用研发技术手段提高汽车发动机结构的精密性。但是，在为消费者带来生活生产便捷的同时，也出现了许多由于发动机故障而引发的事故现象。如果不及时解决此问题，将会给相关汽车行业带来重大损失与不利影响。为了保障驾驶人员的生命安全，减少交通事故发生，预先检测诊断汽车发动机故障问题及相关隐患，是汽车制造行业迫在眉睫需要解决的难题。

2 故障码和数据流简介

2.1 故障码

为了能够及时发现汽车电控系统有关传感器、执行器等电控线路的问题，有必要对相关维修人员在汽车生产过程中的检测筛查能力进行锻炼培训。在监测故障代码的输出运作中，使用专业的故障检测仪读取代码和利用故障报警灯生产代码，通常是监测诊断故障代码的两种主要方式。……
