E100 Low Engine Oil Pressure Warning

Usage:

3516B 9F2
产生此代码的情况:

电子控制模块 (ECM) 可检测以下所有状况:

  • 发动机至少已经运转了 10 秒钟。

  • 机油压力额外低于图 1 内的缺省触发线 4 秒。

  • 100-03 "机油压力与蓄电池正极间开路/短路"处于非激活状态。

  • 100-04 "机油压力与接地间短路"处于非激活状态。

系统响应:

事件代码会记录下来。

  • 发动机润滑系统可能有问题。

  • 发动机机油压力传感器可能故障。

测试步骤 1. 检查有无"激活的"诊断代码。

  1. 启动 Caterpillar 电子技师(ET)。

  1. 将电源转到 ON(接通)位置。

  1. 检查有无任何活动或记录诊断编码。

预期结果:

应无任何诊断代码存在。

结果:

  • 正常 - 应无任何诊断代码存在。 继续测试步骤 2。

  • 异常 - 存在诊断代码。

    修复: 修理出现的诊断代码。 请参阅本手册"利用诊断代码进行故障诊断和排除"章节中的相关专题。 确保修理后故障被排除。

    停止

测试步骤 2. 对发动机润滑系统进行检查。

  1. 对发动机润滑系统进行检查。 请参阅故障诊断和排除, "发动机机油压力偏低"中的诊断步骤。

预期结果:

发动机机油压力没问题。

结果:

  • 正常 - 发动机机油压力没问题。 可能存在间歇性故障。

    修复: 监测发动机的运行。 修理故障。 确保修理后故障被排除。

    停止

  • 异常 - 发动机机油压力有问题。

    修复: 修理故障。 确保修理后故障被排除。

    停止
