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 vehicle controller wiring harness is damaged or broken.检查整车控制器线束是否存在损坏、断裂等现象。 3. Check whether the vehicle controller wiring harness connector is corroded or damaged.检查整车控制器线束接插件是否存在腐蚀、损坏等现象。 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 vehicle controller wiring harness or connector.维修或更换整车控制器线束或接插件。

②Check the high-voltage battery system检查动力电池系统

1. Power status "OFF".电源状态“OFF”。 2. Connect the diagnostic tool.连接诊断仪。 3. Power status "ON".电源状态“ON”。 4. Use a diagnostic tool to check whether the high-voltage battery system is normal.用诊断仪检查动力电池系统是否正常。 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 the high-voltage battery system.检修动力电池系统。

③Check the emergency down wiring harness检查紧急下电线束

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 emergency shutdown wiring harness is normal.检查紧急下电线束是否正常。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 4.去步骤4。 No否 Repair or replace the emergency down wiring harness.维修或更换紧急下电线束。

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。
