Troubleshooting steps故障诊断步骤

①Power on check上电检查

1. Repower the vehicle, use the diagnostic tool to read and clear the fault codes, and check whether the fault codes and symptoms are eliminated.车辆重新上电，使用诊断仪读取并清除故障码，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 2.去步骤2。

②Check forward lidar software version检查前向激光雷达软件版本

1. Check that the forward lidar software version is the latest version.检查前向激光雷达软件版本是否是最新版本。 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 Updated forward lidar software.更新前向激光雷达软件。

③Replacing forward-facing lidar更换前向激光雷达

1. Replace with a new forward-facing lidar and check whether the fault code and symptoms are eliminated.更换新的前向激光雷达，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 forward-facing lidar, you need to use a diagnostic tool to recalibrate the forward-facing lidar.更换前向激光雷达后，需用诊断仪对前向激光雷达重新标定。
