3406E, C-10, C-12, C-15, C-16 and C-18 On-highway Engines Caterpillar


0232-04 5 Volt Supply voltage low (21)

Usage:

3406E 1MM
产生此代码的情况:

发动机控制模块 (ECM) 检测到以下情况:

  • 5 伏电源低于 4.84 VDC 超过 1 秒。

  • ECM 至少已通电三秒钟。

系统响应:

ECM 将记录诊断代码并触发快照。 该诊断代码为激活状态的同时,检查发动机指示灯亮起。 ECM 会将所有压力传感器设为下述缺省值:

  • 大气压力 100 kPa (15 psi)

  • 增压压力 0 kPa (0 psi)

  • 发动机机油压力 500 kPa (73 psi)

当此诊断代码为激活状态时,发动机将会出现动力不足。

测试步骤 1. 进行以下的诊断步骤: 5 伏发动机压力传感器电源电路 - 测试

结果:

  • 正常 - 停止
