如果表 1 中的诊断代码为现行状态,请使用本步骤。

表 1
与配置参数有关的代码    
J1939 代码     CDL 代码     代码说明
(代码说明可能不同)    
注释    
630-2     268-2     已编程参数故障:不稳定、间歇或不正确     发动机电子控制模块(ECM)检测到一个或多个可编程参数未编程设定。
ECM 可能使用一个默认扭矩图表,或者可能将发动机转速限制为低怠速。
代码仅为激活状态。    
遵循故障排除步骤来确定故障根源。    

Caterpillar 电子技师(ET)可用来查看某些会影响发动机运转的参数。 Cat ET 也可用来更改某些参数。 某些参数不能修改,并且某些应用不允许更改可编程监控系统。 这些参数存储在电子控制模块(ECM)中。 这些参数中的一些参数受密码保护,以防擅自更改。 可以被更改的参数有一个记录数。 记录数显示某一参数是否被改动过。

参数分为两种不同的类型:

客户指定参数 - 修改用户指定参数可能需要用户密码。

系统配置参数 - 系统配置参数影响发动机的排放或发动机的功率。 修改系统配置参数的数值可能需要出厂密码。

典型配置屏幕

  1. 连接到 Cat 电子技师。

  1. 选择 Service(维修)栏。

  1. 通过选择 Configuration(配置)栏查看配置参数。

如果更换 ECM,必须从旧 ECM 中复制对应参数。 利用 Cat ET 的 "Copy Configuration(复制配置)"功能复制参数。 "Copy Configuration(复制配置)"栏位于 "Configuration(配置)"栏下方。 另外,也可以将设置记到纸上,然后再将其编程设定到新模块的配置屏幕上。


注意

在发动机运行中修改参数可导致发动机运行不稳定和发动机损坏。

只能在发动机停止时修改参数的设定值。


检查可编程参数(268-2)




图 2g02280534

如果有可编程参数未编程设定,ECM 将产生 268-2 或 630-2 诊断代码。 将在此代码下方列出未编程的可编程参数。 图 2 显示了 268-2 代码下未编程设定的参数。 未编程的参数将被设为默认值。 某些发动机性能和发动机监控功能会爱到影响。

如果 "Injector Trim(喷油器调整)"出现在 Caterpillar 电子技师(ET)上的 268-2 或 630-2 诊断代码下方,请参阅故障诊断与排除, "喷油器调整文件 - 安装"。
