现代汽车广泛采用电子控制技术,其电气设备、系统结构日趋复杂和精密。对汽车各系统和用电设备的控制基本实现了功能组合化、控制电子化和连接标准化,使汽车的性能更加完善。同时对汽车的故障诊断与维修有了更高层次的要求。因此,在对电子控制发动机的故障诊断与维修方面,不能再延续传统的经验检查方法进行故障判断。而应在一定经验积累上,借助先进的检测设备,运用先进的检查方法,结合故障发生原因、现象和检测结果,充分利用技术维修资料,认真思考和分析,判断故障范围,有针对性的解决故障问题。为此,现试就汽车电控发动机无法起动的故障进行分析,指出了故障诊断与排除的方法。
Hyundai Motor widely used electronic control technology, its electrical equipment, system structure increasingly complex and sophisticated. Control of the various automotive systems and electrical equipment basically achieved the functional combination, control of electronic and connection standardization, the performance of the car more perfect. At the same time the car’s fault diagnosis and maintenance have a higher level of requirements. Therefore, in the electronic control of the engine fault diagnosis and repair, can no longer continue the traditional experience of inspection methods to determine the fault. But should accumulate some experience, with advanced testing equipment, the use of advanced inspection methods, combined with the causes of failure, phenomena and test results, make full use of technical maintenance information, careful thinking and analysis, to determine the scope of the fault, targeted solution Fault problem. To this end, the car is now trying to control the engine can not start the fault analysis, pointed out the fault diagnosis and troubleshooting methods.
