Troubleshooting steps故障诊断步骤

①Check coolant检查冷却液

1. Check whether there is enough coolant.检查冷却液是否充足。 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 Go to step 2.去步骤2。

②Check the pipelines related to the motor and water pump检查电机水泵相关管路

1. Check whether the relevant pipeline interfaces of the motor and water pump are well connected and whether they are damaged.检查电机水泵相关管路接口是否连接良好，是否破损。 Are the test results normal?检查结果是否正常？ Yes是 Add coolant that meets specifications.添加符合规格要求的冷却液。 No否 Troubleshoot the corresponding fault.排除相应故障。

③Replace motor water pump更换电机水泵

1. Replace the motor and water pump and check whether the fault code and symptoms are eliminated.更换电机水泵，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。

④Replacing the thermal management integrated module更换热管理集成模块

1. Replace the thermal management integrated module with a new one and check whether the fault code and symptoms are eliminated.更换新的热管理集成模块，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 thermal management integrated module, you need to use a diagnostic instrument to recalibrate the thermal management integrated module.更换热管理集成模块后，需用诊断仪对热管理集成模块重新标定。
