故障现象一辆车辆型号为LZW7128KFA1.2L的宝骏乐骋轿车,发动机型号为LMU,因右前玻璃升降异常送修。故障诊断与排除接车后立即验证故障现象,使用左前门的主控开关控制右前门升降器无任何反应,控制右前后视镜也无反应;使用左前门的主控开关控制左后门升降器时左后和右前门升降器同时升降;单独使用四个门上的开关控制升降玻璃正常。之前维修该车的技师对故障车辆尝试更换了车身控制模块、左前门主开关和右前门升降器开关,但故障无法排除。宝骏乐骋和雪佛兰乐骋玻璃升降系统不一样。雪佛兰乐骋采用传统电路控制车门玻璃升降系统,而上市不久的宝骏乐骋使用的是Lin线控制的升降系统,车身模块是车门玻璃升降的主控模块。
Fault phenomenon A vehicle model LZW7128KFA1.2L Po Chun Le Cheng sedan, engine model LMU, because of the right front glass lift exception repair. Fault diagnosis and troubleshooting immediately after the car to verify the phenomenon of failure, the use of the left front door main control switch to control the right front door lift without any reaction, control the right front and rear mirrors also no response; use the left front door main control switch when the left rear door lifter Left and right front door lifter lift at the same time; separate use of the four door switch to control the normal glass. The technician who had previously repaired the car tried to replace the body control module, the left front door main switch and the right front door lifter switch for the failed car, but the failure could not be ruled out. Baojun Le Cheng and Chevrolet Aveo glass lifting system is not the same. The Chevrolet Aveo uses traditional circuitry to control the door glass lift system, while the soon-to-be listed Baojun Levine uses the Lin line-controlled lift system, with the body module being the main control module for the door glass lift.
