CX48-P2300 Petroleum Transmission Power Train Electronic Control System Caterpillar


Electronic Control Module (ECM) - Flash Program

Usage:

CX48-P2300 GDH
执行下述程序,对 ECM 进行闪存编程。 更新软件时需要对 ECM 进行闪存编程。 如果更换了 ECM,也必须对 ECM 进行闪存编程。

当机器上出现特定类型的操作故障却无法找到原因时,向 ECM 中闪存最新版本的软件可能有助于缓解故障。 以下所列为这些类型故障的部分示例:

  • 出现故障后,无法找到与固件相关的原因。

  • 当钥匙起动开关断开后再接通时,故障反复出现然后消失。

  • 故障疑似由 ECM 引起。

在认定 ECM 为导致这些类型故障的原因前,获取针对您机器配置的最新版本 ECM 软件。 向 ECM 中闪存新版本的软件。 操作机器以确定是否已排除故障。

Cat® 电子技师 (Cat ET) 维修工具中包含程序 WinFlash。 WinFlash 用来将软件加载到 ECM 中。 以下步骤用来将软件闪存到 ECM 中。

执行下述步骤以便将新的软件闪存到 ECM 中。

  1. 步骤

    1. 在通信适配器与安装有 Cat ET 的计算机之间连接一条数据链路电缆。

    1. 在通信适配器与机器的诊断维修接头之间连接一条数据链路电缆。

    1. 将断路开关和钥匙起动开关转到接通位置。 不要起动发动机。

    1. 将锁定开关设定到锁定位置(如适用)。

    1. 确认您闪存的是针对 ECM 配置的最新版本软件文件。

    1. 使用 Cat ET 与要闪存的 ECM 建立通信。

    1. 使用 WinFlash 将软件文件加载到控制模块中。

    1. ECM 闪存完成后,将钥匙起动开关转到断开位置。 等待至少 10 秒。

    1. 将钥匙起动开关转到接通位置持续几秒。 起动发动机。

起动发动机后,在将机器重新投入正常使用前,确认所有机器功能操作正常。
