MID 036 - CID 0253 - FMI 02 Personality Module mismatch
产生此代码的情况:
备用个性模块用于不同的发动机系列或不同的发动机应用场合。
注: 个性模块为闪存文件。 个性模块通过闪存编程装入电子控制模块(ECM)。
系统响应:
ECM 将不记录此诊断代码。 发动机将不起动。 Caterpillar 电子技师(ET)将不能复位此诊断代码。
- 发动机将不起动。
测试步骤 1.
- 检查 ECM 闪存文件的零件号。 确保闪存文件零件号与原始发动机配置总成一致。
预期结果:
ECM 中安装了正确的闪存文件。
结果:
- 正常 - ECM 中安装了正确的闪存文件。
修复: 如果安装了正确的闪存文件,则必须清除诊断代码 253-02。 清除此故障代码需要使用工厂密码。 还必须将个性模块代码复位至零。
停止
- 异常 - ECM 中没有安装正确的闪存文件。
修复: 利用正确的闪存文件重新编程 ECM。 请参阅故障诊断与排除, "闪存编程"。
停止
