| 故障诊断与排除测试步骤 | 数值 | 结果 |
|---|---|---|
1. 检查代码 A. 将 Caterpillar 电子技师（ET）连接到维修工具接头上。 如有必要，请参阅故障诊断与排除, "电子维修工具"。 B. 在执行任何故障诊断与排除或清除故障诊断代码前，从发动机 ECM 下载"产品状态报告"。 C. 确定指向此步骤的故障诊断代码是否存在。 D. 针对指向此步骤的事件代码，检查有无系统相关的激活的诊断代码。 |
E2113 |
结果：存在相关代码。 修理：在继续进行此测试前，诊断并排除所有相关代码。 结果：存在 E2113 代码。 转至下一步。 结果：没有激活的代码 停止 |
2. 检查泵部件 A. 检查有无损坏的后冷器水泵。 B. 检查水泵叶轮有无损坏和磨损。 |
油泵 |
结果：后冷器水泵正常 转至下一步。 结果：水泵不正常 修理：修理或更换水泵。 如果故障未得到排除，转至下一步骤。 |
3. 检查冷却液管路 A. 检查冷却系统部件有无泄漏。 B. 确保独立回路后冷器系统的冷却液液位充足。 |
冷却液泄漏 |
结果：冷却液管路和冷却液液位正常 结果：冷却液管路和冷却液不正常 修理：清除阻塞并更换任何损坏的管路。 |
