following guidelines:

1. Park the vehicle outdoors and

keep people, other vehicles, and

combustible material away from

it.

2. Do not leave the vehicle

unattended.

3. Do not connect any shop

exhaust hoses or vents to the tail

pipe.

CAUTION: Exhaust tempera-

tures may be greater than

300 C (572 F)during service

regeneration.

CAUTION: Due to the elevated

temperatures during this

procedure, open the hood and

keep the front of the vehicle

away from anything impeding

air ﬂ ow to the radiator.

DPF REGENERATION

If you own a newer diesel

powered vehicle, your vehicle is

equipped with a diesel particu-

late ﬁ lter ( DPF). This ﬁ lter is

used in conjunction with a die-

sel oxidation catalyst. Together

they work to reduce the amount

of soot and emissions emitted

from the tailpipe. As soot builds

up in the DPF it will begin re-

stricting the ﬁ lter. The soot that

gathers is automatically purged

in one of two ways: Passive

Regeneration & Active Regen-

eration. Both methods occur

automatically and require no ac-

tion on your part. During either

of these regeneration methods,

you may notice an increase or

change in the exhaust noise &

increased EGT.

PASSIVE REGENERATION

Passive regeneration occurs

when the exhaust temperature

( EGT) reaches an appropri-

ate level in order to oxidize

or burn soot to clean the DPF.

This method can happen as a

result of normal engine operat-

ing conditions, typically when

the engine reaches an EGT high

enough to burn off the soot (i.e.

heavy towing, high load condi-

tions etc.) If EGTs do not get

hot enough to cause passive

regeneration, then your truck’s

engine-control system automati-

cally initiates an active regen-

eration.

ACTIVE REGENERATION

During active regeneration,

the truck computer cleans the

DPF by raising the exhaust

temp to a point where the soot

is burned away. This is accom-

plished through various engine

actions which raise the EGTs

in the oxidation catalyst/ DPF

system to a level where the soot

is burned off. After the soot

is burned off, the EGTs and

back-pressure (restriction) fall
