通讯适配器 II 和 Caterpillar 电子技师(Cat ET)的连接
使用通信适配器 II 和 Cat ET 来确定诊断代码时所需的部件如下:
(1) 电缆
(2) 171-4400 通信适配器 II
(3) 维修诊断电缆。
(4) 最新版本的 Cat ET 软件和一台 IBM 兼容的个人计算机

参考: 请参考专门出版物, NEHS0758, "包含软件的通信适配器 II 用户手册"。

注: Cat ET 是一个可在兼容 IBM 的个人电脑上运行的软件程序。

为了使用 Cat ET,需订购以下资料:专门出版物, JERD2124, "ET 单一使用程序许可", 专门出版物, JEHP1026, "信息和要求表", 7X-1425 数据链路电缆和数据订阅 和 专门出版物, JERD2142, "数据订阅"。 专门出版物, JEHP1026, "信息和要求表"列出了 Cat ET 所需的硬件及特性。

确定诊断代码时不需要使用 Cat ET,清除诊断代码时也不需要使用 Cat ET。 但是,使用 Cat ET 确定诊断代码的过程更快更简单。 Cat ET 还可以显示诊断代码历史记录以及诊断代码参数状态的资料。 这些特性使得 Cat ET 成为故障诊断与排除中有益的工具。

将 Cat ET 连接到诊断接头,即可通过数据链路与电子控制模块通信。 有关接头的位置信息及更多其他信息,请参阅机器维修手册中的故障诊断和排除, "电气部件和接头位置"以及电气系统原理图。

有关维修 Sure Seal 接头的说明,请参考专门说明书, SMHS7531。 有关维修 Deutsch 接头的说明,请参考专门说明书, SEHS9615。

使用数字式万用表来测量电阻或电压。 有关 6V-7070 数字式万用表的说明,请参考专门说明书, SEHS7734。 7X-1710 万用表表笔用于在不断开接头的情况下测量各个接头上的电压。 把表笔电缆沿导线推入接头的背面。 8T-8726 适配器电缆有一个 3 针抽头线束。 适配器电缆用于进行传感器电路的测量。

注: 除了线束测试之外,对于当今的 Caterpillar 机器电气电路不推荐使用例如 8T-0500 导通性测试仪的导通性测试仪或例如 5P-7277 电压测试仪的电压测试仪。
