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 the left B-pillar side impact sensor wiring harness for damage, breakage, etc.检查左B柱侧碰传感器线束是否存在损坏、断裂等现象。
3. Check the left B-pillar side impact sensor harness connector for loose connection or damage.检查左B柱侧碰传感器线束接插件是否存在虚接、损坏等现象。
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 Repair or replace faulty wiring harness or connector.维修或更换故障线束或接插件。
②Check the left B-pillar side impact sensor circuit检查左B柱侧碰传感器线路
1. Check whether the positive terminal of the left B-pillar side impact sensor is short-circuited with the power supply.检查左B柱侧碰传感器正极是否与电源短路。
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 Repair or replace the left B-pillar side impact sensor wiring harness.维修或更换左B柱侧碰传感器线束。
③Replace the left B-pillar side impact sensor更换左B柱侧碰传感器
1. Replace the left B-pillar side impact sensor with a new one and check whether the fault code and symptoms are eliminated.更换新的左B柱侧碰传感器，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 4.去步骤4。
④Replace 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。
