故障现象一辆长丰猎豹越野车,在倒车时示廓灯熔丝频繁熔断。故障诊断经反复试车发现。在未接通示廓灯开关的情况下,该车在向前行驶时,不管是缓慢制动还是紧急制动,示廓灯熔丝均不会熔断,但在倒车时,只要紧急制动,示廓灯熔丝就会熔断,而随着试车次数的增加,在倒车时有时缓慢制动也会使示廓灯熔丝熔断。根据故障现象首先用万用表电阻挡对示廓灯线路进行检测,未发现示廓灯电源线与搭铁短路的现象;检查前车灯总成和后尾灯总成中示廓灯部分,均未发现异常。考虑到故
Fault phenomenon Changfeng Cheetah off-road vehicles, the lights flashing fuse frequently in reverse. Fault diagnosis found by repeated tests. In the case of the switch is not connected to the lights, the car in the forward driving, whether it is slow or emergency braking brake, the outline of the fuse will not blown fuse, but when reversing, as long as the emergency brake, The profile lamp fuse will blow, and as the number of test runs increases, slow braking sometimes reverses the profile lamp fuse. According to the fault phenomenon, first of all, using a multimeter to block the indicator light line circuit detection, did not find the power cable and the ground light short circuit phenomenon; check the front lamp assembly and rear lamp assembly in the outline of the light part, were not found abnormal. Take into account so
