车型:配置3ZR-FAE发动机。行驶里程:26552km。故障现象:发动机故障灯点亮,车速最高95km/h,无法再提升车速故障诊断:连接专用LEXUS诊断仪GTS进入发动机检查故障码,如图1所示。清除故障码后试车,急加速后发动机故障灯依然点亮,故障依旧。于是进行道路试车,使用诊断仪读取CVT变速器数据流(如图2所示),根据维修手册分析如下:
Model: Configuration 3ZR-FAE engine. Mileage: 26552km. Symptom: The engine fault light, the maximum speed of 95km / h, can no longer increase the speed Fault diagnosis: Connect the dedicated LEXUS diagnostic GTS into the engine to check the fault code, as shown in Figure 1. After removing the fault code test, the engine fault light is still lit after the rapid acceleration, the fault still. So for the road test drive, use the diagnostic instrument to read CVT transmission data flow (shown in Figure 2), according to the maintenance manual analysis is as follows:
