Diagnosis and repair procedures诊断和维修流程

Confirm the fault phenomenon确认故障现象

◊

Listen to the customer's description of the fault, reproduce the fault, and record the corresponding phenomena. Do not disassemble until the cause of the fault is determined.倾听客户描述故障发生的情形，进行故障重现，并做好相应的现象记录，在未确定故障原因前请勿进行拆解工作。

circuit analysis电路分析

◊

Refer to the system circuit diagram in the circuit diagram book, and on the basis of understanding the working principle of the circuit, test the entire subsystem circuit from power supply to ground to determine the fault point. If the fault point cannot be determined, other circuits that are common to the faulty subsystem circuit need to be detected, such as referring to fuses, grounding, switches and other common circuits on the circuit diagram. If the utility circuit is working properly, the fault is in the system circuit itself. If several utility circuits are faulty, it may be a faulty fuse or ground.参考电路图册中系统电路图，在理解电路工作原理的基础上对整个子系统电路从电源到接地进行检测，确定故障点。如果无法确定故障点，需要检测与故障子系统电路公用的其他电路，如在电路图上参考保险丝、接地、开关等公用的电路。如果公用电路工作正常，故障就在自身系统电路上，如果几个公用电路都存在故障，可能是保险丝或接地存在故障。

Circuit and electrical component inspection电路及电气元件检查

◊

When checking the circuit, you should refer to the inspection process of circuits and electrical components in the maintenance manual. At the same time, make full use of the fault diagnosis instrument to check the electrical components. Combined with the fault diagnosis process in the maintenance manual, start the inspection from the most likely cause and the easiest electrical component to inspect.进行电路检查时应参考维修手册中对电路及电气元件的检查流程，同时充分利用故障诊断仪进行电气元件的检查，结合维修手册中的故障诊断流程，从最可能的原因及最容易检查的电气元件开始检查。

Troubleshooting故障维修

◊

Find faults and perform necessary repairs. Refer to the circuit diagram and maintenance manual for troubleshooting instructions. For example: ground point repair, connector terminal repair.发现故障，进行必要的维修工作。参考电路图及维修手册中对故障处理方法的描述。例如：接地点维修、接插件端子维修。

Verify that the circuit is working properly验证电路是否正常工作

◊

After the repair work is completed, recheck the system circuit to confirm that the fault has been eliminated. If the fault is a blown fuse, all circuits sharing the fuse should be checked.维修工作结束后，重新检查系统电路以确认故障已经排除。如果是保险丝熔断故障，应检查所有共用该保险丝的电路。

Warning:警告：

♦

Pure electric vehicles contain high voltage. Improper operation during use or maintenance may lead to safety accidents such as electric leakage and electric shock, causing harm to the human body or the vehicle. Therefore, be sure to perform inspections or repairs in the correct order.纯电动车辆含有高电压，使用或维修时操作不当，可能会导致漏电、触电等安全事故，对人体或车辆造成危害。因此，一定要按照正确的顺序进行检查或维修。

♦

Before inspecting and repairing the high-voltage part wiring harness or components, the power supply to the high-voltage power part must be cut off.在检查维修高压部分线束或元件前，必须切断高压动力部分电源。

♦

Always wear insulating protective equipment before inspecting high-voltage systems.检查高压系统前，一定要穿戴绝缘防护设备。
