Keyword:  倒车灯故障排除故障码快速检测控制模块故障现象车辆故障诊断影像客户投诉;
Abstract: <正>VIN:WDD2211541A××××××。故障现象:客户投诉仪表上显示"左后倒车灯"故障,左后倒车灯不亮,同时倒车影像黑屏,无法使用。故障诊断:启动车辆,踩住制动踏板挂入倒挡,仪表显示"左后倒车灯"故障,此时倒车影像正常,但过了约10s后,倒车影像突然黑屏,无显示。连接DAS诊断仪对车辆进行快速检测,检测结果显示后SAM控制模块有故障码存储,如图1所示。故障码内容为左后倒车灯故障或至该部件的线路有短路或断路。据客户反映,该车曾经剐蹭过左后侧,但并没有伤及车辆左后翼子板内的部件及线路,左后尾灯总成刚刚更换过。由此可以排除车辆左后尾灯本身的故障。
