Troubleshooting steps故障诊断步骤

①General inspection一般检查

1. Check for unusual heat sources around the vehicle.检查车辆周围是否存在异常热源。 2. Check whether the ambient temperature of the vehicle is too high.检查车辆所处环境温度是否过高。 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 Move the vehicle away from the current environment.将车辆驶离当前环境。
