Troubleshooting steps故障诊断步骤

①General inspection一般检查
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 low-voltage wiring harness of the charging socket is damaged or broken.检查充电插座低压线束是否存在损坏、断裂等现象。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 2.去步骤2。 No否 Repair or replace the low-voltage wiring harness of the charging socket.维修或更换充电插座低压线束。
②Check charging socket N temperature + signal harness检查充电插座N温度+信号线束
	1. Power status "ON".电源状态“ON”。 2. Use a digital multimeter to measure whether the voltage between pin 5 of the charging socket CS04 and ground is normal.用数字万用表测量充电插座CS04的5号针脚与接地之间的电压是否正常。 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 Repair or replace the charging socket N temperature + signal harness; if the fault persists, go to step 3.维修或更换充电插座N温度+信号线束；若故障依然存在，去步骤3。
③Replace charging socket更换充电插座
1. Replace the charging socket with a new one and check whether the fault code and symptoms are eliminated.更换新的充电插座，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 4.去步骤4。
④Replace vehicle controller更换整车控制器
1. Replace the vehicle controller with a new one and check whether the fault code and symptoms are eliminated.更换新的整车控制器，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 vehicle controller, you need to use a diagnostic tool to recalibrate the vehicle controller.更换整车控制器后，需用诊断仪对整车控制器重新标定。
