0168-00 Excessive ECM Battery Power (17)
产生此代码的情况:
该状况说明发动机运转期间发动机控制模块 (ECM) 的蓄电池供电电路电压过高。
ECM 检测到下述情况时：
- 对于 12 伏系统，ECM 的蓄电池供电电路电压高于 16 伏超过 0.5 秒钟。
- 对于 24 伏系统，ECM 的蓄电池供电电路电压高于 32 伏超过 0.5 秒钟。
ECM 还检测到下述情况：
- 发动机控制置于接通模式。
- 发动机不能进行起动盘车。
- 发动机正运转。
- ECM 至少已通电三秒钟。
系统响应:
ECM 将记录诊断代码。 检查发动机指示灯和报警指示灯可能亮起，就像点火开关刚转到接通位置后起动发动机一样。
无
测试步骤 1. 进行以下的诊断步骤: 点火钥匙开关电路和蓄电池供电电路 - 测试
结果:
- 正常 - 停止
