mission compliance
The aftertreatment system is monitored by diagnostic systems in
the control units to ensure reduced emissions. If the system does
not meet the emission requirements, it should not be possible to
use the machine for work as usual. This takes place by a reduction
of engine power (derate).

:
- The level in the AdBlue®/DEF tank is too low
- AdBlue®/DEF is of low quality
- There is a problem/malfunction with the aftertreatment system
There are two levels of engine power reduction (derate) that are
activated after a certain time depending on the type of problem,
as well as if the malfunction reoccurs or not.

If the engine is restarted (by turning the ignition off and on) when
engine power has been reduced, then full engine power (called
restored engine function) can be obtained twice during derate
level 1. This can be done in case of a danger or hazard and, e.g.,
if the machine has to be moved. This will not extend the time for
activation of derate level 2.
