Event Codes
电子控制模块（ECM）监测发动机运行状况，例如机油压力过低或冷却液温度过高。 如果运行状况超出正常状况，会生成一个事件代码。 事件代码会保持激活，直到状况回复正常。 ECM 也会记录该事件。 事件通常指机械问题而不是电子系统问题。
事件可能以警告、降额或停机的形式出现。 此应用下适用的事件可在本文档此章节内找到。

图 1 显示了模拟传感器的典型输出电压。 如果输出信号电压在 4.2 VDC 和 4.8 VDC 之间，ECM 会生成一个事件代码。
监测系统
电子维修工具可用于编程某些监测系统参数。 可以启用或停用某些功能，对一些激发点进行设定。
请参阅故障诊断与排除, "系统配置参数"中关于监测系统参数的表，以了解各个可以编程的功能。
如果有事件发生，将会采取下列行动之一：
"警告" - 事件发生时，警告灯将持续点亮。
"减额" - 事件发生时警告灯将闪烁，发动机功率将减额。
"停机" - 事件发生时警告灯将闪烁，发动机将停机。
如果有多个减额为激活状态，所显示的减额将会是限制发动机功率最多的减额。
当选定监测系统参数编程为 "Off"（关闭）时，ECM 将不会在事件发生时采取任何行动。 例如，警告灯将不会点亮。
