0111-02 Coolant Level signal invalid (12)
产生此代码的情况:
冷却液液位传感器信号同时指示存在一个偏低和一个正常状况时，就会发生这种情况。 该故障诊断代码出现之前，"冷却液液位传感器"参数必须编程设定在 "4 针"、"2 针开关"或 "2 线式浮子传感器"上。
系统响应:
该故障诊断代码为激活状态的同时，发动机控制模块 (ECM) 设定冷却液液位为正常。
该故障诊断代码为激活状态时，卡特彼勒电子技师 (ET) 状态屏上"发动机冷却液液位"旁边会显示"偏低"和"诊断"。 检查发动机指示灯不亮，除非该故障诊断代码保持激活状态十小时以上。
发动机响应不会因为该故障诊断代码而受到影响。
测试步骤 1. 进行以下的诊断步骤: 冷却液液位传感器电路 - 测试
结果:
- 正常 - 停止
