Troubleshooting steps故障诊断步骤

①General inspection一般检查

1. Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。 2. Check whether the left front collision sensor connector is assembled correctly.检查左前碰撞传感器接插件装配是否正确。 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 Reconnect the left front impact sensor connector.重新连接左前碰撞传感器接插件。

②Check airbag electronic control unit configuration code检查安全气囊电控单元配置码

1. Check whether the airbag electronic control unit configuration code matches the actual vehicle left front collision sensor assembly.检查安全气囊电控单元配置码与实车左前碰撞传感器装配情况是否符合。 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 Reconfigure the airbag electronic control unit configuration code.重新配置安全气囊电控单元配置码。

③Replace airbag electronic control unit更换安全气囊电控单元

1. Replace the airbag electronic control unit with a new one and check whether the fault code and symptoms are eliminated.更换新的安全气囊电控单元，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 airbag electronic control unit, you need to use a diagnostic tool to recalibrate the airbag electronic control unit.更换安全气囊电控单元后，需用诊断仪对安全气囊电控单元重新标定。
