This arrangement requires a regeneration period to clean the "soot" or diesel particulates from the DPF arrangement. The amount of fourth dimension betwixt regeneration periods depends on fuel consumed, hours of engine operation, miles driven, and other factors determined by the engine command module (ECM).

The DFP arrangement should exist able to regenerate automatically during normal driving. The driver may never know the system is undergoing a cleaning cycle.

Still, at that place are several situations where the ECM cannot initiate a DFP regeneration wheel. Those situations include extended idling, end and get traffic, and extended driving under 30 miles per hour.

If for any reason the diesel particulate filter cannot regenerate itself, i of the above error messages will brandish in the drivers information heart.
