If the Parked Regeneration process is ignored, the engine
may derate or stop running.

precautions.
A Preliminary Diesel Oxidation Catalyst (PDOC) (if equipped),
and a DOC operate together to oxidize the injected fuel to
increase the exhaust gas temperature as needed for DPF
Regen.
AFTERTREATMENT (AFT) HIGH-SOOT AUTO ENGINE
SHUT DOWN
When Diesel Particulate Filter (DPF) soot level is high and
extended idling periods occur, the engine performance will be
limited, and if left uncorrected, the engine may shut down. The
DPF indicator will flash and an alarm will beep continuously
while the ignition is on.
This indicates the DPF is full and
engine performance will be limited. Pull the vehicle safely off
the roadway and start Parked Regeneration process to prevent
the engine from stopping.
When the Diesel Particulate Filter Indicator exceeds level three
and the vehicle is idling, engine performance will be severely
limited, and a Parked Regeneration will be required to prevent
engine shut down. When a Regen occurs, do the following:
•
The operator must park the vehicle and then perform the
Regen as required.

ENGINE IDLE SHUTDOWN TIMER (FEDERAL-OPTIONAL)
regulations may limit engine idle time. The vehicle
owner or operator is responsible for compliance with
these regulations.
The optional Idle Shutdown Timer (IST) allows the Engine
Control Module (ECM) to shut down the engine during extended
idle. Idle time can be programmed from 5 - 120 minutes. The
ECM can be programmed to deactivate the IST when the Power
Takeoff (PTO) is active.
Thirty seconds before engine shutdown, the IDLE SHUTDOWN
indicator illuminates. This continues until the engine shuts down
or the low idle shutdown timer is reset. The engine must be out of
gear for the IST to work. Engine shutdown timer will deactivate
for one or more of the following conditions:
Follow the Parked Regeneration process listed in the
Vehicle Operator Manual.
If the Parked Regeneration process is ignored, the engine
may stop running.
