需进行 SCR 诱导超越更新 
E1598 (2)
需要发动机排放操作员诱导紧急超越更新 
本代码指示已激活诱导超越。 

出现紧急情况时,允许没有 Caterpillar 输入的情况下初次激活超越。 激活前,将通过显示屏上的以下信息通知操作员:"EMERGENCY USE ONLY(仅紧急情况使用)。 SEE OWNERS MANUAL(请参见用户手册)。 PENALTIES APPLY FOR MISUSE(误用时的处罚)"。

激活后,检查发动机灯和行动灯也将点亮以警告操作员超越处于激活状态。 代码还将变为激活状态,以指示发动机排放操作员诱导紧急超越激活。 复位超越前代码将保持激活状态。 如果紧急情况在 120 小时的超越操作结束前结束,操作员必须暂停超越。 暂停时,设备将受到诱导(减额)。 如果重现紧急情况,可能会再次激活超越。 使用超越 120 小时后,超越将过期,设备将受到诱导。 激活后,超越复位前检查发动机灯和行动灯将继续点亮。 如果超越过期,代理商需要复位超越以再次使用超越。 复位超越时将清除指示发动机排放操作员诱导紧急超越为激活状态的代码。 复位超越是清除代码的唯一方法。

需要 Cat 代理商在超越过期时使用 Cat® 电子技师 (ET) 复位超越。 超越复位前不能再次使用超越。 警告灯将继续点亮,直到复位超越。 首次激活后,超越可能会在任一点复位。
