北海本田CR-V汽车维修,他行驶时偶尔熄火

一辆行驶里程超20万km的2009年东风本田C R-V运动型多功能车。(北海本田CR-V汽车维修)用户反映:该车在低速行驶过程中偶尔会熄火,但熄火后可以立即再次起动。(北海本田CR-V汽车维修)

检查分析:维修人员接车后连接专用诊断仪HDS读取故障码,在车辆稳定性控制系统(VSA)内发现含义为“IG1电压过低”的故障码。(北海本田CR-V汽车维修)根据维修手册的提示,故障原因可能为:发电机输出电压异常、熔丝异常、ABS泵电源线异常、ABS泵搭铁线G202异常、蓄电池及其连接线异常等。(北海本田CR-V汽车维修)首先检查仪表台下熔丝盒内4号7.5 A熔丝正常,没有虚接的现象。(北海本田CR-V汽车维修)测量熔丝至ABS泵之间的线路正常。(北海本田CR-V汽车维修)由于是偶发故障,于是反复晃动线束并进行测量,结果也显示正常。(北海本田CR-V汽车维修)检查并紧固搭铁点G202,紧固蓄电池连接线。(北海本田CR-V汽车维修)然后连接诊断仪进行路试,随时观察发动机数据流。(北海本田CR-V汽车维修)

试车过程中,驾驶员在大约40 km/h的速度轻踩了一下刹车,仪表板突然暗了一下,随即发动机熄火,仪表又恢复正常。(北海本田CR-V汽车维修)重新起动车辆,发现诊断仪与车辆失去联系,说明是偶尔电压过低导致点火能量不足,从而造成发动机熄火。(北海本田CR-V汽车维修)重点检查发电机、蓄电池及相关线路,发现蓄电池不是原车型号,本着先易后难的原则,更换了蓄电池,继续试车,故障一直未出现。(北海本田CR-V汽车维修)

故障排除:更换蓄电池,并定期进行回访,故障一直未出现。(北海本田CR-V汽车维修)
