产生此代码的情况:


图 1g01816865

Cat 数据链路电路示意图

当底盘 ECM 不以正确的速率向变速箱 ECM 发送必要的参数时,记录此诊断代码。 底盘 ECM 生成参数的更新率不正确。

产生此诊断代码的可能原因如下:

  • 底盘 ECM 软件为不正确软件。

  • 变速箱 ECM 软件为不正确软件。

  • 可能安装了不兼容的软件。

  • 底盘 ECM 的保险丝可能已经熔断。

系统响应:

机器响应如下所示:

  • 一些机具功能可能无法正常工作。

注: 确保诊断代码指示灯和诊断代码都处于激活状态。

测试步骤 1. 检查底盘 ECM 和变速箱 ECM 的软件版本是否正确。

  1. 利用 Caterpillar 电子技师(ET)验证软件版本是否兼容。

预期结果:

底盘 ECM 和变速箱 ECM 上安装了正确的软件版本。

结果:

  • 是 - 软件版本兼容。 转至测试步骤 2。

  • 否 - 未安装正确的软件。

    修复: 闪存相应 ECM 的合适软件。 循环钥匙开关以初始化新软件。 确保诊断代码不再为激活状态。

    停止

测试步骤 2. 重新检查是否有诊断代码。

  1. 确保诊断代码 CID 1273 FMI 14 为激活状态。

预期结果:

诊断代码处于非激活状态。 诊断代码指示灯处于非激活状态。

结果:

  • 是 - 诊断代码指示灯和诊断代码都处于非激活状态。

    修复: 清除诊断代码。

    停止

  • 否 - 诊断代码处于激活状态。

    修复: 请在更换 ECM 之前确保安装了正确的软件。 如果软件正确,则更换变速箱 ECM。 请参阅本手册的测试和调整, "电子控制模块(ECM)- 更换"一节。 如果刚更换了制动器 ECM,则安装新的底盘 ECM。 请参阅本手册的测试和调整, "电子控制模块(ECM)- 更换"一节。

    停止
