LEVEL
REGENERATION NEEDED
Diesel particulate filter is becoming full
solid
The DPF REGENERATION telltale light illuminates to notify
the driver that a stationary regeneration (parked) will be
required soon. When this lamp is lit, initiate stationary
regeneration process at an appropriate time of day. THERE
IS NO URGENCY AT THIS LEVEL.
REGENERATION REQUIRED
Diesel particulate filter full
flashing
If no DPF regeneration occurs after the initial DPF
REGENERATION telltale light illumination, the lamp will
begin blinking and a stationary regeneration should be
initiated as soon as possible in order to prevent from
entering into Level 3.
ATD SERVICE REQUIRED
flashing ENGINE DERATE ACTIVE
+ Diesel particulate filter overfull
If the flashing DPF REGENERATION telltale light is still
ignored, the CHECK telltale light will illuminate. In that
situation, engine performance is limited. Perform a parked
regeneration IMMEDIATELY to avoid further derate and
prevent from entering into Level 4.
ATD SERVICE REQUIRED
flashing ENGINE SHUTDOWN ACTIVE
+ A serious engine problem has occurred. The DPF may be
over its maximum capacity.
If a stationary regeneration is still not initiated, a standard
Engine Protection Shutdown sequence will occur. All of the
+
following dashboard lamps will be present:
Blinking DPF REGENERATION telltale light;
Solid CHECK telltale light;
Solid STOP telltale light.
Once engine derate and/or shutdown sequence is
completed, a stationary regeneration must occur to
continue vehicle operation. If the driver continues to
operate
measures will be taken to protect the engine and ATD from
damage, up to and including engine shutdown. Parked
regeneration might no longer be possible.
If engine protection has been initiated and forces the
engine to shutdown, you CAN immediately re-start the
engine and perform the necessary steps in order to
initiate a stationary regeneration.
