东南菱帅轿车采用先进的无级变速器(CVT),该无级变速器主要部件的位置如图1所示,该无级变速器具有故障自诊断功能。1 故障自诊断功能当该无级变速器系统中各个速度传感器、主带盘油压传感器、副带盘油压传感器、各个电磁阀、CVT 控制继电器、CVT 油温传感器等发生故障时,发动机和 CVT ECU 将记录相应的故障代码并使仪表板上的 N 档指示灯(图2)以约1 Hz 的频率闪烁。注意:如果 N 档指示灯以约2 Hz 的频率 Southeast Lingshuai cars using advanced CVT (CVT), the CVT main components of the position shown in Figure 1, the CVT has a fault self-diagnostic function. 1 fault self-diagnosis function When the CVT system in the various speed sensor, the main reel hydraulic sensor, vice reel hydraulic pressure sensor, each solenoid valve, CVT control relay, CVT oil temperature sensor failure, the engine and CVT The ECU will record the corresponding error code and flash the N range indicator (Figure 2) on the dash panel at about 1 Hz. Note: If the N position indicator lights at a frequency of about 2 Hz
