故障现象一辆行驶里程约为6.7万km的2012年产迈腾车(搭载2.0T发动机和7速双离合变速器),驾驶人反映,开空调后出风口吹出的是自然风。故障诊断用VAS5052A进行检测,各个系统均无相关故障代码存储。根据故障现象分析导致故障的可能原因有调节电磁阀故障;空调压力传感器故障;管路泄漏导致空调系统制冷剂不足;系统电压过低导致车辆进入电能管理状态而切断空调;空调系统线路故障;空调压缩机故障;空调控制模块损坏等。起动发动机,打开空调,AC开关指示灯能正常点
Trouble phenomenon A mileage of about 67,000 km 2012 annual production of MAGOTAN (equipped with 2.0T engine and 7-speed dual clutch transmission), the driver reflects the air outlet after the opening is the natural wind blowing. Troubleshooting VAS5052A for testing, each system has no relevant fault code storage. According to the analysis of the fault phenomenon, the possible causes of the malfunction include the adjustment of the electromagnetic valve, the failure of the air conditioner pressure sensor, the lack of refrigerant in the air conditioning system due to pipeline leakage, the cutoff of the air conditioner due to the system voltage being too low, the failure of the air conditioning system line, Compressor failure; air conditioning control module damage and so on. Start the engine, turn on the air conditioning, AC switch indicator light can be normal
