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。

②Calibration check校准检查

1. Recalibrate the main sensor for monitoring the right front blind spot and check whether the fault code and symptoms are eliminated.对右前盲区监测主传感器重新校准，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 the right front blind spot monitoring main sensor更换右前盲区监测主传感器

1. Replace with a new right front blind spot monitoring main sensor and check whether the fault code and symptoms are eliminated.更换新的右前盲区监测主传感器，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 main sensor for monitoring the right front blind spot, you need to use a diagnostic instrument to recalibrate the main sensor for monitoring the right front blind spot.更换右前盲区监测主传感器后，需用诊断仪对右前盲区监测主传感器重新标定。
