密码

密码是安全系统的一部分,有助于防止未经授权重新编程特定参数。 密码可防止所记录事件未经授权的擦除。 密码能够使工厂控制发动机标定参数的访问权。 密码能够使客户控制特定可编程发动机参数的访问权。

出厂密码

清除任何事件代码时都需要使用出厂密码。 修改 Full Load Setting(满负荷设定)等特定的参数需要工厂密码。 出厂密码将进行更改限制为由经过授权的人员执行。 输入正确的工厂密码后,便可以进行修改。

要想获得正确的工厂密码,必须向经过授权的 Caterpillar 代理商提供特定信息。 由于工厂密码中包含字母字符,因此可以利用电子维修工具执行此功能。 要想获取工厂密码,像已经拥有工厂密码一样执行以下操作。 在某些时候,如果实际需要工厂密码,电子维修工具将请求工厂密码,且电子维修工具将显示获得工厂密码所需的信息。

注: 需要旧的互锁代码以更改旧的 ECM 上的互锁代码。 修改旧 ECM 上的联锁代码还需要新联锁代码。

工厂密码的电子维修工具屏幕将显示以下参数:

  • 电子控制模块 (ECM) 的序列号

  • 发动机序列号

  • 电子维修工具的序列号

  • 原因代码

  • 总更改次数

注: 工厂密码只能用于一个编程会话。 在退出电子维修工具屏幕后,将需要一组不同的工厂密码。 将需要一组不同的密码来更改其他电子维修工具屏幕上的信息。
