MID 036 - CID 0253 - FMI 02 Personality Module mismatch
产生此代码的情况:
替换用闪存文件适用于不同的发动机系列或不同的发动机应用类型。
系统响应:
电子控制模块(ECM)将不记录此代码。 Caterpillar 电子技师(ET)不能清除该代码。
可能对性能的影响:
燃油喷射停用。 发动机无法起动。
故障诊断和排除:
测试步骤 1. 检查闪存文件的零件号
- 采用 Cat ET 确认闪存文件的零件号符合维修技师工作台(STW)或 SIS 网络上提供的最新信息。
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: 在清除 253-02 诊断代码之前,发动机将无法起动。 清除该代码需要使用出厂密码。
获取出厂密码。 清除 253-02 诊断代码。 发动机返回进行维修。
停止
- 异常 - ECM 中没有安装正确的闪存文件。
修复: 使用正确的闪存文件重新闪存编程设定 ECM。 请参阅故障诊断和排除, "闪存编程"。 确认故障已排除。
停止
