Table 5-6: Performing A Parked Regeneration (Detroit)
* These steps not required on GHG14 engines or later.
DD13 Operators may notice a slight increase in vehicle vibration during regeneration. The DD13 engine will fire
three cylinders during regeneration and operate the other three in engine brake mode. This increases engine load
during regeneration and increases exhaust temperatures.
1. Move the truck to a safe location that prevents the high exhaust heat from causing damage to the road surface
or the ground.
• Park on a clean surface that will not melt or burn (clean concrete or gravel, not grass or asphalt).
• Engine control should be from accelerator pedal (not PTO, remote PTO, cruise, etc) PTO and running
at normal idle (high idle should be OFF).
• Clear exhaust outlet area 5 ft of any items, gasses, vapors that can melt, burn or explode.
• If indoors, exhaust discharge pipe must be rated at least 1500°F (816°C).
2. Cycle the transmission out of neutral and back into neutral.*
3. Cycle the parking brake OFF to ON - once an ignition cycle (Parking Brake must remain ON).*
STAY with the vehicle. Monitor the area during the operation. if any unsafe conditions occur, shut off
engine immediately!
NOTE:
Diesel Particulate Filter (DPF) lamp must be ON in order to start a stationary regeneration.
4. With the engine running at idle, and the vehicle parked with the speedometer at 0 mph, press and hold the
vehicle’s regeneration switch for 5 seconds.
• Engine speed increases. (Series 60: 1600 RPM. DD13: 1100 RPM).
• DEF lamp flashes then turns OFF. As hydrocarbons are added, temperature goes up. HEST lamp
flashes once every ten seconds, then illuminates when exhaust temperature reaches 977°F (525°C).
• Regeneration may take up to 40 minutes or more, depending on soot level.
• Exhaust temps stay high at least 5 minutes after completion.
5. To stop a regeneration before completion, press the regeneration inhibit switch, place the vehicle in gear,
release the parking brake, or turn off the engine.
6. When the regeneration is complete, the engine returns to normal idle speed and operation.
— If excessive soot remains in the filter, the DPF light(s) will return to the appropriate stage until another
regeneration occurs. Repeat parked regeneration. If the DPF light still remains on, call for service.
