注意

如果所装闪存文件并非设计用于此发动机,运转发动机后会造成损坏。 一定要在发动机上安装正确的闪存文件。


注: 出厂密码只向 Caterpillar 代理商提供。

执行下述各功能时需要出厂密码:

  • 对新电子控制模块(ECM)进行编程。

    更换 ECM 时,必须将系统配置参数编程设置到新 ECM 中。 如果不使用出厂密码,新 ECM 只允许对这些参数编程设置一次。 初始编程设置之后,某些参数将受出厂密码保护。

  • 恢复发动机的额定值。

    这可能需要更改受出厂密码保护的联锁代码。

  • 解锁参数。

    解锁某些系统配置参数时需要使用出厂密码。 请参阅故障诊断与排除, "配置参数"。

  • 清除发动机事件和某些诊断代码。

    大部分发动机事件代码都需要使用出厂密码才能从 ECM 存储器中清除。 只有在确定故障已被排除的情况下才能清除这些代码。 比如,发动机超速代码需要使用出厂密码才能从 ECM 存储器中清除。

出厂密码包含字母字符,因此必须使用 Caterpillar 电子技师(ET)来执行这些功能。 为获取出厂密码,请像密码已经到手一样执行上述功能。 如果需要出厂密码的话,Cat ET 会要求输入出厂密码,而且 Cat ET 会显示获取密码所需提供的信息。 关于用来获取出厂密码的工作表,请参阅维修故障诊断与排除, "出厂密码工作表"。
