SERVICE REGENERATION LEVEL
For Deere engines, the most severe level is the service regen level. At this level, the DPF lamp is
blinking and the red alarm lamp illuminates. When the service level is reached, the engine ECU has
determined that the situation is severe and a service regeneration is necessary. At the service regen
level, the engine ECU may de-rate the engine or prevent it from starting and the message shown
below appears on the display.
REGEN INHIBIT
The panel provides two methods for “inhibiting” a regeneration process. The first method is to answer
“No” to the Regen Request message when it appears on the display. The second method is to select
“Inhibit Regen” in the Emissions Configuration Menu (under Regen Options). The two available
settings are “Auto” and “Inhibit Regen”.
The “Auto” setting allows the engine ECU to initiate and control the regeneration process. The “Inhibit
Regen” setting delays the regeneration process. The “Inhibit Regen” setting only delays the
regeneration process until higher levels of severity are reached. At higher levels of severity, the engine
ECU no longer accepts the “Inhibit Regen” message from the panel.
When the “Inhibit Regen” setting is selected, the inhibit lamp illuminates.
