Troubleshooting steps故障诊断步骤

①Power-on inspection (take the left rear blind spot monitoring main sensor as an example for inspection)上电检查(以左后盲区监测主传感器为例进行检查)

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。

②Calibrate left rear blind spot monitoring main sensor校准左后盲区监测主传感器

1. Calibrate the left rear blind spot monitoring main sensor according to the standard, and check whether the fault code and symptoms are eliminated.按照标准校准左后盲区监测主传感器，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 Go to step 3.去步骤3。

③Replace the left rear blind spot monitoring main sensor更换左后盲区监测主传感器

1. Replace with a new left rear blind spot monitoring main sensor and check whether the fault code and symptoms are eliminated.更换新的左后盲区监测主传感器，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 left rear blind spot, you need to use a diagnostic instrument to recalibrate the main sensor for monitoring the left rear blind spot.更换左后盲区监测主传感器后，需用诊断仪对左后盲区监测主传感器重新标定。
