Oil pump working abnormally (self-developed)油泵工作异常(自研)

①General inspection一般检查
1. Check the oil pump controller wiring harness for damage, breakage, etc.检查油泵控制器线束是否存在损坏、断裂等现象。 2. Check the oil pump controller wiring harness connector for loose connection or damage.检查油泵控制器线束接插件是否存在虚接、损坏等现象。 Are the test results normal?检查结果是否正常？ Yes → Go to step 2.是>>去步骤2。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
②Check fuse检查保险丝
1. Power status "OFF".电源状态“OFF”。 2. Check whether the oil pump controller fuse is blown.检查油泵控制器保险丝是否熔断。 Are the test results normal?检查结果是否正常？ Yes → Go to step 3.是>>去步骤3。 No → Replace the fuse with the same specification.否>>更换相同规格保险丝。
③Check oil pump controller fault code检查油泵控制器故障码
1. Use a diagnostic tool to read the fault code of the oil pump controller and check whether there is a fault in the oil pump controller.使用诊断仪读取油泵控制器故障码，检查油泵控制器是否存在故障。 Are the test results normal?检查结果是否正常？ Yes → Go to step 4.是>>去步骤4。 No → Troubleshoot the oil pump controller fault according to the fault code.否>>根据故障码排除油泵控制器故障。
④Check CAN communication line检查CAN通讯线路
1. Check whether the CAN communication line of the oil pump controller is normal.检查油泵控制器CAN通讯线路是否正常。 Are the test results normal?检查结果是否正常？ Yes → Go to step 5.是>>去步骤5。 No → Check the CAN communication line.否>>检修CAN通讯线路。
⑤Check the oil pump controller power circuit检查油泵控制器电源线路
	1. Power status "ON".电源状态“ON”。 2. Use a digital multimeter to measure the voltage between pin 6 of the oil pump controller harness connector FB62 and ground.用数字万用表测量油泵控制器线束接插件FB62的6号针脚与接地之间的电压。 Standard voltage value: about 14V标准电压值：约14V Are the test results normal?检查结果是否正常？ Yes → Go to step 6.是>>去步骤6。 No → Repair or replace the oil pump controller power wiring harness.否>>维修或更换油泵控制器电源线束。
⑥Check the oil pump controller ground circuit检查油泵控制器接地线路
	1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Disconnect the oil pump controller harness connector FB62.断开油泵控制器线束接插件FB62。 3. Use a digital multimeter to measure the resistance between pin 5 of FB62 and ground.用数字万用表测量FB62的5号针脚与接地之间的电阻。 Standard resistance value: <1标准电阻值：＜1 Ω Are the test results normal?检查结果是否正常？ Yes → Go to step 7.是>>去步骤7。 No → Repair or replace the oil pump controller grounding harness.否>>维修或更换油泵控制器接地线束。
⑦Replacing the integrated electric drive assembly更换集成电力驱动总成
1. Replace the integrated electric drive assembly and check whether the fault is eliminated.更换集成电力驱动总成，检查故障是否排除。 Are the test results normal?检查结果是否正常？ Yes → Fault resolved.是>>故障排除。 No → Find the cause from other fault symptoms.否>>从其他故障现象查找原因。   Caution:注意： ♦  After replacing the integrated electric drive assembly, you need to use a diagnostic tool to recalibrate the integrated electric drive assembly.更换集成电力驱动总成后，需用诊断仪对集成电力驱动总成重新标定。
