Troubleshooting steps故障诊断步骤

①Check ambient temperature检查环境温度

Check whether the ambient temperature is too high.检查环境温度是否过高。

Check for abnormal temperature sources near the vehicle.检查车辆附近是否存在异常温度源。

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

Let the vehicle cool down in a suitable environment; if the fault persists, go to step 2.将车辆置于合适环境下静置冷却；若故障依然存在，去步骤2。

②Check cooling system检查冷却系统

Check whether the cooling system is normal.检查冷却系统是否正常。

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

Check the cooling system.检修冷却系统。

③Replacing the integrated electric drive assembly更换集成电力驱动总成

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。
