REGENERATION NEEDED
Diesel particulate filter is becoming full
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.
LEVEL 2
flashing
REGENERATION REQUIRED
Diesel particulate filter full
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
ENGINE DERATE ACTIVE
Diesel particulate filter overfull
If the flashing DPF Regeneration telltale light is still ignored, the CHECK

ATD SERVICE REQUIRED
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:
l
Blinking DPF Regeneration telltale light;
l
Solid CHECK telltale light;
l
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 the vehicle without regeneration, additional
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.
Find and solve the cause of the shutdown
