0128-03 Secondary Fuel Level voltage high
产生此代码的情况:
只有 GMT-560 应用才使用该故障诊断代码。
ECM 检测到下述情况：
- 辅助燃油油位信号电压高于容许范围超过 10 秒钟。
系统响应:
如果已编程设定"主燃油箱型号"参数并且主燃油油位传感器的故障诊断代码为非激活状态，ECM 将使用主燃油油位传感器确定燃油油位。
如果没有编程设定"主燃油箱型号"参数并且主燃油油位传感器的故障诊断代码为激活状态，ECM 将通过 J1939 数据链路发布一个故障代码。 ECM 还经 ATA 数据链路发布 0 燃油油位。
该故障诊断代码为激活状态时，电子维修工具状态屏上"辅助燃油油位"旁边会显示"诊断"。
测试步骤 1. 进行以下的诊断步骤: 燃油油位传感器电路 - 测试
结果:
- 正常 - 停止
