Description: Silent Code That Logs When the Diesel Particulate Filter Regeneration Lamp is
Flashing in ” Regen Zone 2″.
Troubleshooting:
NOTE: This code is informational only and used by service to help understand which dash
lights illuminated during normal service. A stationary regeneration is required if the fault code is
active. No action is required for an inactive fault code.
POSSIBLE CAUSES:
Stationary regeneration is needed.

Description: Diesel Particulate Filter Has Reached the End of its Service Life
Troubleshooting:
NOTE: Using alternate cleaning methods may result in the cleaned DPF failing to reach the
next Ash clean interval. The customer may experience damage to the diesel oxidation catalyst
(DOC) or DPF assemblies as a result of alternate cleaning methods.
POSSIBLE CAUSES:
Faulty DPF
