Troubleshooting steps故障诊断步骤

①Power on check上电检查
1. Repower the vehicle, use the diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.车辆重新上电，使用诊断仪读取并清除故障码，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 2.去步骤2。
②Check fuse检查保险丝
	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. Check whether the battery-positive fuse box DCDC fuse is normal.检查正极保险盒DCDC保险丝是否正常。 DCDC：200A Are the test results normal?检查结果是否正常？ Yes是 Go to step 3.去步骤3。 No否 Replace the fuse with the same specification.更换相同规格的保险丝。
③Check DCDC output voltage检查DCDC输出电压
1. Power status "ON".电源状态“ON”。 2. Use a digital multimeter to measure the voltage between the positive and negative terminals of the 12V battery.用数字万用表测量蓄电池正负极之间的电压。 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是 Fault resolved.故障排除。 No否 Check the DCDC harness; if normal, go to step 4.检查DCDC线束；若正常，去步骤4。
④Replacing the integrated electric drive assembly更换集成电力驱动总成
1. Replace the integrated electric drive assembly with a new one and check whether the fault code and symptoms are eliminated.更换新的集成电力驱动总成，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Look for causes from other symptoms.从其他症状查找原因。   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。
