		2. The motor water pump is damaged2.电机水泵损坏
		3. Motor water pump software failure3.电机水泵软件故障

Troubleshooting steps故障诊断步骤

①Check inside the motor water pump检查电机水泵内部

1. Check whether there is any foreign matter stuck inside the motor water pump.检查电机水泵内部是否有异物卡滞。 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 Clean up foreign objects.清理异物。

②Using a diagnostic tool to drive a motor water pump使用诊断仪驱动电机水泵

1. Use a diagnostic tool to drive the motor and water pump alone to check whether the fault code and symptoms are eliminated.使用诊断仪单独驱动电机水泵，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 3.去步骤3。

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。
