CID 0168 FMI 01
产生此代码的情况:
此代码说明发动机运转期间，发动机控制模块（ECM）的蓄电池电路电压过低。 如果蓄电池电压在没有返回的情况下消失，ECM 将不记录该故障诊断代码，同时发动机停机。
ECM 检测到下述情况时：
- 钥匙开关处于 接通位置。
- 发动机没有进行起动盘车。
- 发动机已经运转 3 秒以上。
- ECM 的蓄电池电压低于 9 伏的时间超过 0.5 秒。
系统响应:
ECM 将会记录此诊断代码。
发动机将减额。
控制面板显示屏会出现一条警告。
引起该故障诊断代码的状况仍然存在时，发动机可能发生转速变化、间歇性停机或完全停机。
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
