MID 082 - CID 2166 - FMI 13
产生此代码的情况:
该诊断代码与铲刀向右侧移电磁阀有关。 ECM 检测到电磁阀需要进行标定时就会激活诊断代码 FMI 13。
机具 ECM 向电磁阀提供一个 PWM 输出信号以便实现电磁阀的比例控制。 ECM 将会根据从右操纵手柄组件中的铲刀侧移位置传感器接收到的输入指令改变 PWM 输出信号的电流。
注: 进行此步骤之前,确认电磁阀没有其他激活的 CID 2166 诊断代码存在。 如果此电磁阀的其他诊断代码处于现行状态,执行此步骤前务必纠正相关问题。
测试步骤 1. 标定
- 执行电磁阀的标定步骤。 关于正确的标定步骤,请参阅本手册的测试和调整, "标定"部分。
预期结果:
成功执行标定步骤。
结果:
- 是 - 成功执行标定步骤。 使机器恢复正常运转。停止
- 否 - 标定不成功。
修复: 执行电磁阀的标定步骤。如果第二次标定步骤失败,则更换电磁阀。 在更换电磁阀后,请参考本手册的测试和调整, "标定"部分以了解正确的标定步骤。 如果更换和标定新电磁阀后问题依然存在,则表明 ECM 可能已经损坏。更换 ECM 之前,务必先咨询当地代理商的技术通信员征求 Caterpillar 可能的意见。 此咨询可以大大降低维修时间。 如果没有找到该诊断代码的原因,则应更换 ECM。 请参考《测试和调节:, "电子控制模块 (ECM) - 更换"》。
