  1. 利用 9U-7402 多用转速表工具总成 测量风扇转速。 请参阅专门说明书, NEHS0605, "9U-7400 多用转速表 II 总成和 9U-7402 多用转速表 II 总成"。

  1. 清理一个风扇叶片上的某区域后粘贴一条反光胶带。 将反光胶带粘贴到光学传感器可见的区域上。

  1. 将光学传感器的磁座固定到风扇护罩上。 确保光学传感器和反光胶带对齐。

最低风扇转速

  1. 将配有电子技师的笔记本电脑通过通信适配器连接到机器上。

  1. 起动发动机并以低怠速运转发动机。

  1. 在电子技师(ET)中选择 Engine ECM(发动机 ECM)。

  1. 从 "Diagnostics(诊断)"菜单选择 "Override Parameters(超越参数)"。

  1. 选择 "Engine Fan Bypass(发动机风扇旁通)"和输入 "100%"。

  1. 记录多用转速表工具总成屏幕上显示的读数。 低怠速下的风扇转速应当为 600 rpm ± 100 rpm。

  1. 停止发动机。

    如果风扇转速不正确,请参阅系统操作、测试和调整, "风扇驱动系统故障诊断与排除"。
