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 right B-pillar side impact sensor wiring harness for damage, breakage, etc.检查右B柱侧碰传感器线束是否存在损坏、断裂等现象。 3. Check the right B-pillar side impact sensor harness connector for loose connection or damage.检查右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 right B-pillar side impact sensor circuit检查右B柱侧碰传感器线路

1. Check whether the right B-pillar side impact sensor circuit is short-circuited to ground.检查右B柱侧碰传感器线路是否对地短路。 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 right B-pillar side impact sensor wiring harness.维修或更换右B柱侧碰传感器线束。

③Replace the right B-pillar side impact sensor更换右B柱侧碰传感器

1. Replace the right B-pillar side impact sensor with a new one and check whether the fault code and symptoms are eliminated.更换新的右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。
