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. Normal DPF ash clean interval is every 150,000 miles (241,000 km) (5,000 hrs)* |
||||
| DEF Pump Filter | Replace every 500,000 miles (805,000 km) (10,000 hrs) (3 years)* | ||||
| Air Compressor | Inspect every 55,000 miles (88,000 km) (1,800 hrs) (18 months)* | ||||
|
*Whichever comes first. Note: Reaching the Davco change line supersedes these intervals. **Detroit highly recommends exchanging the DPF with a Detroit™ genuine DPF to ensure maximum life. |
