3126B and 3126E On-highway Engines Caterpillar


0006-11 Cylinder #6 Injector current fault (74)

Usage:

3126B 1AJ
产生此代码的情况:

发动机控制模块 (ECM) 尝试操作喷油器后检测到以下情况之一:

  • 气缸喷油器电磁阀线路中的电流偏低(开路)。

  • 喷油器电磁阀中的电流偏高(短路)。

系统响应:

ECM 将记录诊断代码并触发快照。 该故障诊断代码为激活状态的同时,检查发动机指示灯亮起。 存在激活的故障诊断代码时将不能自动进行"断缸测试"。

该故障诊断代码为激活状态时喷油器可能不工作。 可能存在以下情况:

  • 发动机缺火

  • 功率偏低

测试步骤 1. 进行以下的诊断步骤: 喷油器电磁阀电路 - 测试

结果:

  • 正常 - 停止
