Driver monitoring system not working驾驶员监测系统不工作

①Check the wiring harness connector检查线束接插件
1. Check the driver status monitoring camera wiring harness for damage, breakage, etc.检查驾驶员状态监测摄像头线束是否存在损坏、断裂等现象。 2. Check the driver status monitoring camera harness connector for loose connection or damage.检查驾驶员状态监测摄像头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 2.是>>去步骤2。 No → Repair or replace the faulty wiring harness or connector.否>>维修或更换故障线束或接插件。
②Check the vehicle infotainment head unit fault code检查车载智能多媒体主机故障码
1. Use the diagnostic tool to read the fault code of the infotainment head unit and check whether there is a fault in the infotainment head unit.使用诊断仪读取车载智能多媒体主机故障码，检查车载智能多媒体主机是否存在故障。 Are the test results normal?检查结果是否正常？ Yes → Go to step 3.是>>去步骤3。 No → Troubleshoot the fault of the vehicle-mounted intelligent multimedia host according to the fault code.否>>根据故障码排除车载智能多媒体主机故障。
③Check driver condition monitoring camera wiring检查驾驶员状态监测摄像头线路
	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 driver status monitoring camera harness connector BD50 and the vehicle infotainment head unit harness connector IP56.断开驾驶员状态监测摄像头线束接插件BD50和车载智能多媒体主机线束接插件IP56。 3. Use a digital multimeter to measure the resistance between pin 1/2 of BD50 and pin 1/5 of IP56.用数字万用表测量BD50的1/2号针脚与IP56的1/5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 driver condition monitoring camera wiring harness.否>>维修或更换驾驶员状态监测摄像头线束。
④Replace driver status monitoring camera更换驾驶员状态监测摄像头
1. Replace the driver status monitoring camera and check whether the fault is eliminated.更换驾驶员状态监测摄像头，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。
