AFTERTREATMENT SYSTEM
HOT EXHAUST
During parked regeneration the
exhaust gases will be extremely
HOT and could cause a fire
if directed at combustible
materials. The vehicle must be
parked outside.
NOTE:
The driver MUST stay with the vehicle
throughout the regeneration process.
NOTE:
Not all vehicles may be equipped
with a regen request switch due to
application or user specification.
NOTE:
The procedure will take 20 to 40
minutes (depends on engine type and
the amount of soot accumulated in the
filter).
To initiate a parked regeneration, the
following must occur:
□ Locate Regen request switch on
dash board. This is a momentary
style switch see Figure 26
□ If no regen request switch is
present, DDDL 7.0 must be
connected for initiation using the
service routines menu. Select
"DPF Regen Request Start."
