Aftertreatment System (ATS)

A Check Engine Indicator or mileage/time intervals indicate when ash cleaning is required. Use DETROIT Diesel Corporation's authorized DPF cleaning procedure. Failure to follow this procedure could result in engine and/or aftertreatment damage, causing degraded vehicle performance including excess fuel consumption and decreased engine life.

Once the DPF has reached maximum ash volume, the recommended service for the DPF is to remove the DPF and replace with a Reliabilt® clean DPF. Using alternate cleaning methods, instead of replacing the DPF at the required interval, may result in the cleaned DPF failing to reach the next ash clean interval. The aftertreatment may experience damage to the DOC, DPF or SCR assemblies as a result of alternate cleaning methods. Cleaning accumulated ash from the DPF is a necessary part of vehicle maintenance.

The DEF filter is considered a maintenance item and will require periodic maintenance. The aftertreatment system should be serviced per estimated maintenance intervals, Preventive Maintenance Tables.
