Maintenance and Specifications When the engine control module detects that the DPF is nearly full of particulates and that the vehicle is not being operated in a manner to allow effective automatic cleaning, the message center will display DRIVE TO CLEAN EXHAUST FILTER for base message center and Drive to Clean Exhaust System for the optional message center, guiding the vehicle operator to drive in order to clean the DPF. If the vehicle is operated in a manner to allow effective automatic cleaning, the message center will display a cleaning exhaust filter message, which is the normal regeneration process. See Message center in the Instrument Cluster chapter of the Owner Guide for more information. Note: You can also choose OCR to clean the exhaust system at this point. See How to start operator commanded regeneration (OCR) later in this chapter. If the operator is not able to drive in manner that allows effective automatic cleaning (active regeneration) or the operator instead wishes to perform regeneration of the DPF (cleaning) while at idle (stationary), then OCR (operator commanded regeneration) will need to be performed. See Operator commanded regeneration (OCR) following. Note: Do not disregard the DRIVE TO CLEAN EXHAUST FILTER or Drive to Clean Exhaust System maintenance message for extended periods of time. Failure to perform active or operator commanded regeneration (OCR) (if equipped) when instructed may result in a clogged DPF. If your DPF fills beyond what can be safely regenerated, active regeneration and OCR will be disabled. This could cause irreversible damage to the DPF, requiring service and possible replacement that may not be covered by your warranty. Operator Commanded Regeneration (OCR) (if equipped) If your vehicle is operated with significant stationary operation, passive and active regeneration may not sufficiently clean the DPF system. OCR allows you to manually start regeneration of the diesel particulate filter (DPF) at idle (while stationary) to clean the DPF. If you are not sure whether your vehicle is equipped with this feature, contact your authorized dealer. When to perform OCR Use the OCR feature when the DRIVE TO CLEAN EXHAUST FILTER message appears in the message center and: • the operator is not able to drive in manner that allows effective automatic cleaning (active regeneration), • or the operator instead wishes to manually start regeneration (cleaning) of the DPF while the vehicle is idle (stationary). 58 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)

When the engine control module detects that the DPF is nearly full of
particulates and that the vehicle is not being operated in a manner to
allow effective automatic cleaning, the message center will display
DRIVE TO CLEAN EXHAUST FILTER
for base message center and
Drive to Clean Exhaust System
for the optional message center,
guiding the vehicle operator to drive in order to clean the DPF. If the
vehicle is operated in a manner to allow effective automatic cleaning, the
message center will display a cleaning exhaust filter message, which is
the normal regeneration process. See
Message center
in the
Instrument
Cluster
chapter of the
Owner Guide
for more information.
Note:
You can also choose OCR to clean the exhaust system at this
point. See
How to start operator commanded regeneration (OCR)
later in this chapter.
If the operator is not able to drive in manner that allows effective
automatic cleaning (active regeneration) or the operator instead wishes
to perform regeneration of the DPF (cleaning) while at idle (stationary),
then OCR (operator commanded regeneration) will need to be
performed. See
Operator commanded regeneration (OCR)
following.
Note:
Do not disregard the
DRIVE TO CLEAN EXHAUST FILTER
or
Drive to Clean Exhaust System
maintenance message for extended
periods of time. Failure to perform active or operator commanded
regeneration (OCR) (if equipped) when instructed may result in a
clogged DPF. If your DPF fills beyond what can be safely regenerated,
active regeneration and OCR will be disabled. This could cause
irreversible damage to the DPF, requiring service and possible
replacement that may not be covered by your warranty.
Operator Commanded Regeneration (OCR) (if equipped)
If your vehicle is operated with significant stationary operation, passive
and active regeneration may not sufficiently clean the DPF system. OCR
allows you to manually start regeneration of the diesel particulate filter
(DPF) at idle (while stationary) to clean the DPF. If you are not sure
whether your vehicle is equipped with this feature, contact your
authorized dealer.
When to perform OCR
Use the OCR feature when the
DRIVE TO CLEAN EXHAUST FILTER
message appears in the message center and:
•
the operator is not able to drive in manner that allows effective
automatic cleaning (active regeneration),
•
or the operator instead wishes to manually start regeneration
(cleaning) of the DPF while the vehicle is idle (stationary).
