The left rearview mirror cannot be adjusted左后视镜无法调节

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 the wiring harness for damage, breakage, etc.检查线束是否存在损坏、断裂等现象。 3. Check whether there is any loose connection or damage to the wiring harness connector.检查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 touch control screen检查触摸控制屏
1. Check whether the touch control screen is working properly.检查触摸控制屏工作是否正常。 Are the test results normal?检查结果是否正常？ Yes → Go to step 4.是>>去步骤4。 No → Inspect the touch control screen.否>>检修触摸控制屏。
④Check vehicle infotainment head unit fault code检查车载多媒体主机故障码
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 5.是>>去步骤5。 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。
⑤Check the left rearview mirror adjustment motor control harness检查左后视镜调节电机控制线束
	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 left rearview mirror harness connector FL06 and the left front door control module harness connector FL17.断开左后视镜线束接插件FL06与左前门控制模块线束接插件FL17。 3. Use a digital multimeter to measure the resistance between pins 2/1/3 of FL06 and pins 1/2/4 of FL17.用数字万用表测量FL06的2/1/3号针脚与FL17的1/2/4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 6.是>>去步骤6。 No → Repair or replace the left rearview mirror adjustment motor control harness.否>>维修或更换左后视镜调节电机控制线束。
⑥Replace left rearview mirror assembly更换左后视镜总成
1. Replace the left rearview mirror assembly and check whether the fault is eliminated.更换左后视镜总成，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 7.否>>去步骤7。
⑦Replace left front door control module更换左前门控制模块
1. Replace the left front door control module and check whether the fault is eliminated.更换左前门控制模块，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 left front door control module, you need to use a diagnostic tool to recalibrate the left front door control module.更换左前门控制模块后，需用诊断仪对左前门控制模块重新标定。
