ECM - Replace
在更换 ECM 之前,确保更换是必需要做的操作。 ECM 不太可能是故障的原因。 务必检查并确认 ECM 标有 "+ Battery(蓄电池正极)"的所有触点上有电。
注: 配置软件损坏或软件不正确可能会导致 ECM 报告错误的诊断代码。 更换 ECM 前,向 ECM 中闪存正确的配置软件,以确认故障与软件损坏无关。 请参阅故障诊断与排除, "ECM 软件 - 安装"。
步骤
- 将断路开关和钥匙起动开关转到断开位置。
- 从 ECM 上断开机器线束接头。
- 确认更换的 ECM 的零件号正确。
- 安装更换的ECM。
- 将机器线束与 ECM 相连。
- 将断路开关和钥匙起动开关转到接通位置。
- 如有必要,使用 Cat® 电子技师 (Cat ET) 维修工具安装配置软件。 请参阅本手册中的测试和调整, "ECM(Electronic Control Module,电子控制模块)- 闪存编程"一节。
- 确认 ECM 正常工作。
