trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.
By simply driving your Dodge truck at highway speeds
for as little as 45 minutes you can remedy the condition in
the particulate filter system and allow your Cummins
engine and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.

Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an ex-
tended period of time after the initial warning notifica-
tion, the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.
CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it’s capacity the
overhead console in your Dodge truck will chime twice
and display the message CATALYST FULL SERVICE
REQD. At this point the engine PCM will register a fault
code, the instrument panel will display a MIL light and
the engine PCM will derate the truck reducing its horse-
power and torque output.
The PCM derates the engine in order to limit the likeli-
hood of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your Dodge truck
dealer.
