E058 Low Engine Coolant Level Shutdown
产生此代码的情况:
发动机已经运转 1 分钟，但冷却液液位传感器仍未检测到冷却液液位。
系统响应:
电子控制模块（ECM）会记录该事件。
Caterpillar 电子技师（ET）在状态屏幕上显示 "Injection Disabled（喷油停用）"。
发动机停机。
测试步骤 1. 检查发动机冷却液液位。
- 检查发动机冷却液液位。 请参阅操作和保养手册, "冷却系统冷却液液位 - 检查"。

加压的系统： 热的冷却液能造成严重的烫伤。 在发动机停机，等待冷却系统部件冷却下来后再打开冷却系统加注口盖。 缓慢松开冷却系统加注口盖，以释放掉所有压力。 |
预期结果:
冷却液液位没问题。
结果:
- 正常 - 冷却液处于适当的液位。 冷却液液位传感器可能有问题。
修复: 测试冷却液液位传感器的工作情况。 请参阅故障诊断与排除, "冷却液液位传感器电路 - 测试"。
停止
- 异常 - 冷却液液位低。
修复: 向冷却系统加注适当的冷却液。 确认修理已排除故障。
停止
