故障描述
车辆行驶过程中及长下坡时,打开排气制动开关,排气制动阀不工作,不起制动作用。
故障分析
分析可能存在故障的部位有:
1、 排气制动开关损坏;
2、 排气制动电磁阀短路、短路;
3、 排气制动蝶阀卡死;
4、 排气制动管路损坏,漏气;
5、 下车排气制动相关线束;
6、 发动机ECU模块故障。
故障处理1.检查
检查时发现打开排气制动开关,排气制动指示灯亮,说明排气制动控制开关信号进入发动机ECU,开关正常。
2.检查排气制动电磁阀
检查排气制动电磁阀,测量电磁线圈阻值约为24欧姆,电磁阀正常。
3.测电压
测量排气制动电磁阀线束插头内电压,304#对327#无电压,304号线对地为24V,此为正常,排气制动电磁阀由发动机ECU直接提供24V电源,由ECU控制负极通断来实现电磁阀的开启和关闭。
4.判断
测量发动机ECU控制负极的端口K47与排气制动电磁阀插头处327号线不通,判断线路有断路现象(见上图),导致排气制动电磁阀无法吸合、蝶阀不工作。
5.查找
通过查找与车架对接的插件,发现有松动情况,维修该处连接线路后,故障解决。
