Intervention Regeneration Strategy — EVIC

Message Process Flow

This engine meets all required diesel engine emissions

standards. To achieve these emissions standards, your

vehicle is equipped with a state-of-the-art engine and

exhaust system. These systems are seamlessly integrated

into your vehicle and managed by the Powertrain Control

Module (PCM). The PCM manages engine combustion

to allow the exhaust system’s catalyst to trap and

burn Particulate Matter (PM) pollutants, with no input or

interaction on your part.

Additionally, your vehicle has the ability to alert you to

additional maintenance required on your vehicle or engine.

Refer to “Electronic Vehicle Information Center (EVIC)”

in “Understanding Your Instrument Panel” for further

information.

• Exhaust System — Regeneration Required Now —

_Exhaust Filter XX% Full Safely Drive at Highway

Speeds to Remedy_ will be displayed on the Electronic

Vehicle Information Center (EVIC) if the exhaust particulate

filter reaches 80% of its maximum storage

capacity. Under conditions of exclusive short duration

and low speed driving cycles, your Cummins® diesel

engine and exhaust after-treatment system may never

reach the conditions required to remove the trapped

PM. If this occurs, the “Exhaust Filter XX% Full Safely

Drive at Highway Speeds to Remedy” message will be

displayed in the EVIC. If this message is displayed,

you will hear one chime to assist in alerting you of this

condition

• By simply driving your vehicle at highway speeds for

as little as 45 minutes, you can remedy the condition in

the particulate filter system and allow your Cummins

® diesel engine and exhaust after-treatment system

to remove the trapped PM and restore the system

to normal operating condition.



• Exhaust System — Regeneration In Process Exhaust

Filter XX% Full — Indicates that the Diesel Particulate

Filter (DPF) is self-cleaning. Maintain your current

driving condition until regeneration is completed.



• Exhaust System — Regeneration Completed — This

message indicates that the Diesel Particulate Filter

(DPF) self-cleaning is completed. If this message is

displayed, you will hear one chime to assist in alerting

you of this condition.



• Exhaust Service Required — See Dealer Now — This

messages indicates regeneration has been disabled due

to a system malfunction. At this point the engine

Powertrain Control Module (PCM) will register a fault

code, the instrument panel will display a MIL light.



CAUTION!

See your authorized dealer, as damage to the exhaust

system could occur soon with continued operation.



• Exhaust Filter Full — Power Reduced See Dealer —

This message indicates the PCM has derated the

engine to limit the likelihood of permanent damage to

the after-treatment system. If this condition is not

corrected and a dealer service is not performed, extensive

exhaust after-treatment damage can occur. To

correct this condition it will be necessary to have your

vehicle serviced by your local authorized dealer.



CAUTION!

See your authorized dealer, as damage to the exhaust

system could occur soon with continued operation.

Sounds like u really need a gde tune

I hope they are lining your pockets for those plugs daily.

In all seriousness... a person shouldn't need a tune for a factory emissions equipped truck to function properly.

Follow @John advice and take a nice highway drive to give the DPF time to clean itself out and hopefully go back to performing as expected.
