How to perform a parked regeneration on your 2010 EPA Compliant International Truck.
We are going to walk you through how to perform a parked regeneration on 2010 EPA Compliant International Truck. The emission systems main component is the Diesel Particulate Filter (DPF) which removes soot from the exhaust stream prior to emission. It is important to maintain the DPF by following the steps below to avoid downtime when the DPF filter becomes clogged. Read through the steps below!
4 stages of soot load: Low soot load, Moderate soot load, Full soot load and Over-Full soot load.
Low Soot Load: This occurs when the DPF indicator light is a solid yellow. When this light comes on it means that the DPF filter is starting to become full. The DPF needs to heat up to turn the soot into ash. There are two ways to accomplish this: Run on the highway for a long period of time (>60km/hr) or perform a forced parked regeneration.
Moderate Soot Load: If your DPF indicator light is flashing yellow, driving at highway speed is no longer enough. When this happens, you must pull over and perform a parked regeneration. Pull over safely on a paved or gravel surface. Do not perform a parked regeneration on grass or soil as the exhaust becomes very hot and can cause a fire.
STEP ONE:
Before initiating Parked Re-Gen, make sure the following 4 conditions are met:
- DO: place truck in neutral
- DO: engage parking brake
- DO NOT: touch the brake or clutch pedals during the process
- DO: make sure the engine coolant temperature doesn’t exceed 170 F, 76.6 C.
STEP TWO:
Once those 4 conditions have been met, push and hold the Engine Re-Gen button for 2 seconds.
You should notice:
- The REGEN switch will illuminate
- NOTE: if the indicator is blinking, check to make sure all the conditions in step 2 are met.
- The engine revving higher than normal, to a preset RPM and a light will appear to the left of the DPF indicator that says TEMP (exhaust temp, NOT engine temp) This TEMP light should not stay on once the Re-Gen cycle is completed.
Re-Gen cycle can take from 20 to as long as 60 minutes, at which time:
- the switch light will go off,
- Engine RPMs will return to normal idle, and
- the DPF indicator light will be off.
If all those conditions are met, you can get back out on the road.
Full Soot Load: Eventually, the DPF will be clogged to the point where engine performance is compromised. When this happens, the flashing DPF indicator light will be accompanied by 5 short beeps each minute.
- IMPORTANT: Pull over as fast, but as safely as possible.
- Repeat the steps described above or risk engine shutdown.
This should breakdown the soot enough so you can continue under full power, BUT the filter has reached the point where its almost completely clogged with ash and its needs to go in for servicing; Make an appointment with your dealer to have the filters serviced ASAP.
Over-Full Soot Load: If the DPF isn’t cleaned for any length of time, it will begin to de-rate – but more importantly, at some point the engine will shut down on you without much warning. You’ll know this is about to happen when a big red indicator light – a hexagon with an exclamation mark – will appear in the middle of your dash.
When the red hexagon indicator light comes on follow these steps:
- Pull over as soon as safely possible,
- Put your hazard lights on
- Shut off the truck
- DO NOT hit the re-gen button
- Call your driver manager and or your International dealer and tell them what’s happened and ask for a tow to the nearest service location.
