例1桂林大宇GDW6113B车发动机冷却液温度过高故障现象一辆桂林大宇GDW6113B型客车,驾驶人反映该车在上坡时冷却液温度升高很快,有时上升到警报线;发动机动力变差,行驶在相同的上坡路段,与车辆正常时相比需要减一个挡位才行。故障诊断该车装用斗山DL08高压共轨柴油发动机,维修技术人先利用车载故障自诊断系统调取故障代码,但没有故障代码;怀疑是车载故障自诊断系统本身有问题,用故
Example 1 Guilin Daewoo GDW6113B engine coolant temperature is too high Fault phenomenon Guiyang Daewoo GDW6113B type bus, the driver reflects the car uphill slope when the coolant temperature rises quickly, and sometimes rose to the alarm line; engine power worse, Driving in the same uphill section, compared with the normal vehicle when you need to reduce a gear job. Fault diagnosis The car equipped with Doosan DL08 high-pressure common rail diesel engine, maintenance technicians first use of vehicle fault self-diagnostic system to retrieve the fault code, but no fault code; suspected vehicle fault self-diagnosis system itself has problems
