Directional Shift Management Function
方向变换管理功能用于减小传动系在方向换档过程中的压力。 在方向变换中，变速箱/底盘 ECM 向发动机 ECM 发送一个信号。 该信号用于减小燃油流，从而减小换档过程中的扭矩。
当发动机转速高于 1000 rpm，而操作员将变速箱移出空档位置时，方向变换管理功能启动。 另外，当发动机转速高于 1000 rpm，而操作员将变速箱操纵杆移动经过空档位置时，方向变换管理功能启动。 变速箱/底盘 ECM 发送一个指令，短时间将"期望发动机转速"降低至低怠速。
方向变换管理功能还可记录变速箱误用。 请参见系统操作, "指示器功能"中有关变速箱误用事件的更多信息。
