 The central control unlocking function fails中控解闭锁功能失效

①General inspection一般检查
1. Power status "OFF".电源状态“OFF”。
2. Connect the diagnostic tool.连接诊断仪。
3. Power status "ON".电源状态“ON”。
4. Use a diagnostic tool to read the fault code and check whether there is a fault.用诊断仪读取故障码，检查是否存在故障。
Check if there is a fault code?检查是否存在故障码？
Yes → Troubleshoot related faults according to the fault code.是>>根据故障码排除相关故障。
No → Go to step 2.否>>去步骤2。
②Check the wiring harness connector检查线束接插件
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 door central control switch wiring harness is damaged or broken.检查左前门集控开关线束是否存在损坏、断裂等现象。
3. Check the left front door central control switch harness connector for loose connection or damage.检查左前门集控开关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 → Go to step 3.是>>去步骤3。
No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
③Check the central control unlocking signal harness检查中控解闭锁信号线束
Graphic
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 left front door control module harness connector FL16 and the left front door centralized control switch harness connector FL12.断开左前门控制模块线束接插件FL16与左前门集控开关线束接插件FL12。
3. Use a digital multimeter to measure the resistance between pin 12/10 of FL16 and pin 5/7 of FL12.用数字万用表测量FL16的12/10号针脚与FL12的5/7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 → Go to step 4.是>>去步骤4。
No → Repair or replace the central control unlocking signal harness.否>>维修或更换中控解闭锁信号线束。
④Replace the left front door centralized control switch更换左前门集控开关
1. Replace the left front door centralized control switch and check whether the fault is eliminated.更换左前门集控开关，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → Fault resolved.是>>故障排除。
No → Go to step 5.否>>去步骤5。
⑤Replacing the integrated body control module更换集成式车身控制模块
1. Replace the integrated body control module and check whether the fault is eliminated.更换集成式车身控制模块，检查故障是否排除。
Are the test results normal?检查结果是否正常？
Yes → Fault resolved.是>>故障排除。
No → Find the cause from other fault symptoms.否>>从其他故障现象查找原因。
  Caution:注意：
♦  After replacing the integrated body control module, you need to use a diagnostic tool to recalibrate the integrated body control module.更换集成式车身控制模块后，需用诊断仪对集成式车身控制模块重新标定。
