EXHAUST REGENERATION — DIESEL ONLY
• Under certain conditions, your Cummins ® diesel engine and exhaust
after-treatment system may never reach the conditions required to remove the
trapped particulate matter. If this occurs, the “Exhaust System —
Regeneration Required Now” message will be displayed on the EVIC screen in
your cluster and you will hear one chime to alert you of this condition. Driving
your vehicle at highway speeds for as little as 45 minutes can remedy the
condition and allow the engine and exhaust after-treatment system to remove
the trapped particulate matter.
• PLEASE NOTE: Under typical operating conditions, NO indications of
regeneration state will be displayed. If you do reach 80% of filter capacity, the
following messages will assist you in inducing and understanding the
regeneration process.
Exhaust System — Regeneration Required Now
• “Exhaust System—Regeneration Required Now” will be displayed on the EVIC
if the exhaust particulate filter reaches 80% of its maximum storage capacity.
Exhaust Filter XX% Full
• Indicates that the Diesel Particulate Filter (DPF) is approaching full.
Exhaust System — Regeneration in Process
• Indicates that the Diesel Particulate Filter (DPF) is self-cleaning. Maintain your
current driving condition until regeneration is completed.
Exhaust System — Regeneration Completed
• 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.
Service Required — See Dealer Now
• Regeneration has been disabled due to a system malfunction. The Powertrain
control Module (PCM) will register a fault code and the instrument panel will
display the MIL light.
Exhaust Filter Full — Power Reduced See Dealer
• The PCM derates the engine in order 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. 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.
