Troubleshooting on Gear Lever Cannot Move Issue of 2012 SAIC Volkswagen Tiguan

文章主要通过对某2012款上汽大众SVW6451JFD途观SUV车换挡杆不能移动的案例进行诊断仪检测,发现自动变速器控制模块与诊断仪无法通信,故进入发动机系统检测,读取相关数据流,无异常,进入09系统检测,发现多个电子控制单元(包含变速器控制模块)无信号/无通信-间断,因此依据自动变速器控制模块电路图,对其供电电源进行检测,发现控制模块的15供电熔断丝异常。更换熔断丝后,故障顺利排除。

The article mainly conducts diagnostic instrument testing on a 2012 SAIC Volkswagen SVW6451JFD Tiguan SUV with a gear shift lever that cannot be moved.It is found that the automatic transmission control module cannot communicate with the diagnostic instrument,so it enters the engine system for testing,reads relevant data flow,and has no abnormalities.After entering the 09 system for testing,it is found that multiple electronic control units(including the transmission control module)have no signals/communication interruptions.Therefore,based on the circuit diagram of the automatic transmission control module,the power supply is tested,and it is found that the 15 power supply fuse of the control module is abnormal.After replacing the fuse,the fault is successfully eliminated.
