Engine Monitoring System
电子控制模块(ECM)监控发动机的运转参数。 如果发动机特定参数超出发动机监控系统规定的允许范围,ECM 将生成诊断代码。 有关诊断代码的信息,请参阅故障诊断与排除, "诊断故障代码" 以了解有关此应用的适用诊断代码列表。
每个参数可能会具有以下三种响应。 有些响应对某些参数是无效的。 请参阅表 1。

使用电子维修工具查看监控系统参数的当前设置。 电子维修工具也可以用于重新编程参数设置和延长时间。
参数的默认设置是在出厂时编程设置的。 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。
注: 有些参数不需要密码即可进行更改。 有些参数的更改需要用户密码。 有些参数受工厂密码的保护。 有些参数可能不用更改。 有些应用不允许对可编程监控系统进行任何更改。 受到工厂密码保护的参数只能由代理商的工作人员进行更改。
有关更改发动机监控系统参数的信息,请参阅系统操作部分, "发动机监控参数"。
