故障现象一辆江淮瑞风A6 0车(车辆型号为HFC7151CTV),右前和右后车窗玻璃均无法升降。故障诊断用故障检测仪检测,发现车身控制模块(BCM)中存储了2个故障代码,分别为“U1F3287 LIN1到副驾驶侧‘APM防夹模块’通信超时”和“U1F5287 LIN1到右后‘APM防夹模块’通信超时”。分析该车电动车窗系统控制电路(图2),得知左前和左后车窗玻璃升降器的供电来自熔丝PF7(30 A),右前和 Fault phenomenon A JAC Refine A6 0 car (vehicle model HFC7151CTV), the right front and right rear window glass can not be raised and lowered. Fault diagnosis detected by the fault detector and found Body Control Module (BCM) stored two fault codes, respectively, "U1F3287 LIN1 to the co-pilot ’APM anti-pinch module’ communication timeout ’’ and ’U1F5287 LIN1 to the right Post ’APM anti-pinch module’ communication timeout ’. Analysis of the car electric window system control circuit (Figure 2), that the front left and rear rear window regulator power supply from the fuse PF7 (30 A), the front right and
