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 touch control screen检查触摸控制屏
1. Check whether the touch control screen is working properly.检查触摸控制屏是否工作正常。 Are the test results normal?检查结果是否正常？ Yes → Go to step 6.是>>去步骤6。 No → Replace the touch control screen.否>>更换触摸控制屏。
⑥Check air conditioning compressor power circuit检查空调压缩机电源线路
	1. The power status is "ON" and the air conditioning cooling function is turned on.电源状态“ON”，开启空调制冷功能。 2. Use a digital multimeter to measure the voltage between pin 4 of the air conditioning compressor harness connector FB64 and ground.用数字万用表测量空调压缩机线束接插件FB64的4号针脚与接地之间的电压。 Standard voltage value: about 12V标准电压值：约12V Are the test results normal?检查结果是否正常？ Yes → Go to step 7.是>>去步骤7。 No → Repair or replace the air conditioning compressor power wiring harness.否>>维修或更换空调压缩机电源线束。
⑦Check air conditioning compressor grounding circuit检查空调压缩机接地线路
	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 air conditioning compressor wiring harness connector FB64.断开空调压缩机线束接插件FB64。 3. Use a digital multimeter to measure the resistance between pin 2 of FB64 and ground.用数字万用表测量FB64的2号针脚与接地之间的电阻。 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 8.是>>去步骤8。 No → Repair or replace the air conditioning compressor grounding harness.否>>维修或更换空调压缩机接地线束。
⑧Check the air conditioning compressor LIN communication line检查空调压缩机LIN通讯线路
	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 air conditioning compressor wiring harness connector FB64 and the thermal management integrated module wiring harness connector FB43.断开空调压缩机线束接插件FB64和热管理集成模块线束接插件FB43。 3. Use a digital multimeter to measure the resistance between pin 3 of FB64 and pin 8 of FB43.用数字万用表测量FB64的3号针脚与FB43的8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 9.是>>去步骤9。 No → Repair or replace the air conditioning compressor LIN communication harness.否>>维修或更换空调压缩机LIN通讯线束。
⑨Replace air conditioning compressor更换空调压缩机
1. Replace the air conditioner compressor and check whether the fault is eliminated.更换空调压缩机，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。
