Front center airbag circuit resistance is too high前排中央气囊回路阻值过高
1. The front center airbag circuit resistance is too high1.前排中央气囊回路阻值过高
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 front center airbag connector assembly is firm and reliable.检查前排中央气囊接插件装配是否牢固、可靠。
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 front center airbag connector.重新连接前排中央气囊接插件。
②Check the wiring harness between the airbag electronic control unit and the front center airbag检查安全气囊电控单元至前排中央气囊之间的线束

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. Disconnect the airbag electronic control unit harness connector BD51 and the front center airbag harness connector BD65.断开安全气囊电控单元线束接插件BD51和前排中央气囊线束接插件BD65。
3. Use a digital multimeter to measure the resistance between pin 3/4 of BD51 and pin 1/2 of BD65.用数字万用表测量BD51的3/4号针脚与BD65的1/2号针脚之间的电阻。
Standard resistance value: <1标准电阻值：＜1 Ω
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 wiring harness between the airbag electronic control unit and the front center airbag.维修或更换安全气囊电控单元至前排中央气囊之间的线束。
③Replace front center airbag更换前排中央气囊
1. Replace the front center airbag with a new one and check whether the fault code and symptoms are eliminated.更换新的前排中央气囊，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。
