Aftertreatment Maintenance
A high amount of black smoke emitting from the vehicle or illumination of the
Amber Warning Lamp or Red Stop Lamp are indications of a system problem.
Should this occur, consult your local Detroit™ Service Center.
Illumination of the Malfunction Indicator Lamp (MIL) Lamp indicates a failure of
an emissions control device. The MIL may illuminate along with other ATS
warning lamps. Call for service to repair the fault.
Illumination of the Diesel Particulate Filter (DPF) Regeneration Lamp indicates
that a parked regeneration is required.
There is a need to periodically remove accumulated ash, derived from engine lube
oil, from the filter. This ash does not oxidize in the filter during the regeneration
process and must be removed through a cleaning procedure. All Detroit™ ATD
equipped engines will illuminate a dashboard warning lamp indicating the need for
ash cleaning.
