Engine Monitoring System
电子控制模块（ECM）为该发动机提供了一个综合的发动机监控系统。 ECM 监控指定的发动机操作参数，以检测可能会发生的异常情况。 如果特定发动机参数超过发动机监控系统定义的可接受范围，则 ECM 将产生一个诊断代码。 ECM 将会根据该情况的严重程度做出反应。 关于诊断代码方面的信息，请参阅故障诊断与排除, "故障诊断代码"。
以下行动可能由 ECM 触发。 这些行动取决于情况的严重程度。
- 点亮警告灯或警告报警
- 发动机减额
- 发动机停机
使用电子维修工具执行监控系统的以下活动：
- 查看参数
- 参数编程
- 设置延迟时间
参数的默认设置已在出厂时进行了编程。 为适应特殊的应用和场所，可使用电子维修工具重新编程一些参数。 使用电子维修工具更改监控系统参数。
注: 某些参数不能修改。 有些应用不允许对可编程监控系统进行任何更改。
