Injector Trim File
利用电子维修工具将喷油器的调整文件加载至电子控制模块(ECM)。
如果发生下述任何情况,必须向 ECM 中加载喷油器调整文件:
- 更换喷油器。
- 更换 ECM。
- "喷油器调整"显示在电子维修工具 268-02 诊断代码下方。
- 在气缸之间调换喷油器。
调换喷油器
调换喷油器有助于确定故障是在喷油器还是在气缸。 如果在气缸之间调换已装在发动机上的两只喷油器,则还必须在气缸之间调换喷油器调整文件。 按下电子维修工具"喷油器调整标定"屏幕底部的"调换"按钮。 选择需要调换的两只喷油器,然后按下 "OK(确定)"按钮。 被调换喷油器的更改次数会增加一次。
- 记录各喷油器的喷油器序列号和喷油器确认代码。
注: 喷油器序列号和喷油器确认代码位于喷油器上。 在此过程中,电子维修工具可能需要输入喷油器确认代码。 如有必要,电子维修工具将提示您的代码。
- 点击 SIS 网站中的 "Service Software Files(维修软件文件)"。
- 在搜索区输入喷油器的序列号。
- 将喷油器调整文件下载至PC。 根据需要,对各喷油器重复本程序。
- 将电子维修工具连接到诊断接头上。 请参阅故障诊断与排除, "电子维修工具"。
- 请选择电子维修工具的下列菜单选项:
- "维修"
- "标定"
- "喷油器调整标定"
- "维修"
- 选择适当的气缸。
- 点击 "Change(更改)"按钮。
- 从 PC 中选择适当的调整文件。
- 点击 "Open(打开)"按钮。
- 如果电子维修工具弹出提示,请在字段中输入喷油器确认代码。
- 点击 "OK(确定)"按钮。
将喷油器调整文件加载至 ECM 中。
- 根据需要,对各气缸重复本程序。 如果喷油器调整文件下载失败,请确认喷油器的零件号是否正确。 重复上述测试步骤。
