故障现象一辆2010款迈腾2.0T轿车(采用2.0TSI发动机,6速02E自动变速器),累计行驶里程约为2.76万km,因行驶过程中发动机突然熄火而向我公司报修。故障诊断赶到现场后发现,该车发动机可以起动着机,但是仪表盘上不显示挡位,踩制动踏板时仪表盘上的提示灯不亮(图1),排挡杆旁的P指示灯闪烁,换挡杆无法从P位移出。连接VAS 5052A进入车身自诊断系统,发现02-自动变速器控制单元无法达到(图2),进入19数据总线诊断接口,系统存储有故障代码01315——变速器控制单元无信号/通讯静态(图3),该故障代码不能清除。检查相关熔丝,无烧蚀;将蓄电池断电后试验,故障依旧。看来现场不能解决,只好将其拖回服务站维修。
Failure phenomenon A 2010 MAGOTAN 2.0T sedan (with 2.0TSI engine, 6-speed 02E automatic transmission), the cumulative mileage of about 27,600 km, due to the engine suddenly turn off and repair to our company. Troubleshooting found on the scene and found that the car engine can start the machine, but does not show the gear on the dashboard, step on the brake pedal indicator light does not shine on the dashboard (Figure 1), P gear indicator next to the gear Blinking, shift lever can not be shifted out of P position. The VAS 5052A is connected to the vehicle body self-diagnosis system and found that the 02- automatic transmission control unit can not be reached (Figure 2). It enters the 19 data bus diagnostic interface and the system stores error code 01315 - Transmission control unit no signal / communication static (Figure 3) The fault code can not be cleared. Check the relevant fuse, no ablation; the battery after power failure test, the fault still. It seems the scene can not be solved, had to drag it back to the service station maintenance.
