0244-02 Event Recorder Data Lost (02)
产生此代码的情况:
在更换 ECM 个性化模块或首次安装新 ECM 时，可导致此诊断代码产生。
ECM 检测到下述情况时：
- 无开关蓄电池连接已经从 ECM 上断开。
系统响应:
清除了 "Driver（操作员）"和 "Fleet Trip Segment（车队行程段）"数据。
Caterpillar 电子技师（Cat ET）将指示 "Trip Totals（行程总计）"是否已清除。 少量的 ECM "总计数据"可能会丢失。
如果记录了大量此类诊断代码，则说明"无开关蓄电池正极"与开关蓄电池相连，或者卡车上使用了蓄电池断路开关。
无
记下所记录诊断代码的次数。 短暂起动发动机。 将钥匙转到 Off 位置。 将钥匙留在 Off 位置大约 2 分钟。 将钥匙转到 On 位置。 检查是否记录了其他诊断代码。 如果记录了其他诊断代码，则无开关线路的连接不正确。
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
