AFTERTREATMENT SYSTEM
The

and
vehicle
Aftertreatment System to capture soot and other particulates
before they exit the exhaust pipe. The soot is captured by the
Diesel Particulate Filter (DPF) and is periodically converted to
carbon dioxide (CO
) by a Regeneration (Regen) process.
2
The Regen process may take place during vehicle operation
(Active Regen). The Active Regen process will be triggered by
either a time-based soot or a soot mass buildup-based strategy.
A Parked Regen process is required when sufficient thermal
energy has not been present to initiate the process for Diesel
Oxidation Catalyst (DOC) light off. The vehicle is required to be
parked (stationary).
•
A Parked Regeneration will be requested if the Regeneration
cannot be completed during driving.
•
In this case, a dash-mounted lamp will be lit to alert the driver
to perform a Parked Regeneration.
•
The driver must park the vehicle and then perform the Regen
as required.
•
Follow the Parked Regeneration process listed in the Vehicle
Operator Manual.
•
If the Parked Regeneration process is ignored, the engine
may stop running.

A DOC operates to oxidize the injected fuel to increase the
exhaust gas temperature as needed for DPF Regen.
ENGINE IDLE SHUTDOWN TIMER (U.S.
FEDERAL-OPTIONAL [2010 AND 2011 VEHICLES])
GOVERNMENT REGULATION: State and local
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 2 to 120 minutes. The
ECM can be programmed to deactivate the IST when the 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:
