3406E, C-10 and C-12 On-highway Engines Caterpillar


Cruise Control, Idle, or PTO Can Not Be Set

Usage:

3406E 1LW

可能原因

故障的根本原因如下:

  • 客户指定参数(正常工作)

  • 巡航控制和怠速控制接通/断开开关

  • PTO 接通 / 断开开关

  • 设定/恢复开关

  • 行车制动器开关电路

  • 离合器开关电路

  • 车速电路

建议的措施

按次序进行下述诊断步骤:

  1. 当利用巡航控制接通/断开开关设定巡航控制或怠速控制时,利用 Cat ET 检查配置。 检查下列参数:

    • "巡航控制车速设定下限"

    • "巡航控制车速设定上限"

    • "怠速车速限制"

    • "怠速转速限制"

    注: 如果车速超过 "High Cruise Control Set Speed Limit(巡航控制车速设定上限)"并且操作员试图设定巡航控制车速,则巡航设定车速便是 "High Cruise Control Set Speed Limit(巡航控制车速设定上限)"。 如果车速低于 "Low Cruise Control Set Speed Limit(巡航控制车速设定下限)",则不能设定或恢复巡航控制。 如果发动机转速高于怠速转速限制并且操作员试图设定怠速发动机转速,则怠速发动机转速便是怠速转速限制。 如果操作员试图设定怠速发动机转速并且车速超过怠速车速限制,则不能启动怠速。 请参阅故障诊断与排除, "巡航控制开关电路 - 测试"。

  1. 当利用 PTO 接通/断开开关设定 PTO 时,利用 Cat ET 检查配置。 检查下列参数:

    • "PTO 配置"

    • "PTO 车速限制"

    • "PTO 发动机转速上限"

    • "PTO 驾驶室控制转速限制"

    请参阅故障诊断与排除, "PTO 开关电路 - 测试",以了解更多信息。

  1. 在数据链路接头上连接 Cat ET。 检查以下控制的状态屏幕:

    • 巡航控制和怠速控制接通/断开开关

    • PTO 接通 / 断开开关

    • 设定/恢复开关

    • 行车制动器开关电路

    • 离合器开关

    • 车速

    1. 在查看 Cat ET 上状态屏幕的同时,接通巡航控制和怠速控制的接通/断开开关。 状态屏幕应当指示开关在 ON 和 OFF 之间变化。 如果问题与巡航控制和怠速控制的接通/断开开关有关,请参阅故障诊断与排除, "巡航控制开关电路 - 测试"。

    1. 在查看 Cat ET 上状态屏幕的同时,将设定/恢复开关从 SET(设定)切换到 RESUME(恢复)。 状态屏幕应当指示开关在 ON 和 OFF 之间变化。 如果问题与设定/恢复开关有关,请参阅故障诊断与排除, "巡航控制开关电路 - 测试"。

    1. 在查看 Cat ET 上状态屏幕的同时,踩下行车制动器。 状态屏幕应当指示踏板已踩下或松开。

    1. 在查看 Cat ET 上状态屏幕的同时,踩下离合器。 状态屏幕应当指示踏板已踩下或松开。
