摘　　要：随着现代汽车技术的不断更新,通常利用故障诊断仪进行读取故障代码来确定汽车故障部位,以解决故障。但有些故障发生并不会产生故障代码,可以利用故障诊断仪来读取数据流了解汽车的工作状况,及时诊断汽车故障。文中针对一例水温传感器出现故障导致汽车起动困难的案例来说明汽车数据流对故障诊断的重要性。Fault codes, which are produced by fault diagnosis instrument, are generally used to locate the Vehicle failure.However, some of the failure doses not generate fault codes. Thus, Data flow is applied to display the working condition of automobile. This paper proves the importance of data flow for fault diagnosis by presenting a case in which a temperature sensor failure results in automotive starting difficulty.
