What causes a regen?
What causes a regen?
A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.
What’s the regeneration process on a Cummins ISX?
• Press “Force regeneration switch” for at least 2-7 seconds. • If Regeneration is accepted, RPM will rise until regeneration is complete. Regeneration Process Cummins Engine Note: Prior 2009 models had regeneration switch inside the cab in driver controls.
Why does my Cummins DPF fail all the time?
Long haulers typically deal with this while loading/unloading, or while idling the engine all night to keep the cab warm during mandatory breaks. Vocational trucks may deal with this all day long, operating in PTO mode for hours, clogging up the DPF while being unable to regen. This is why DPF’s tend to fail so frequently.
What’s the best way to troubleshoot a Cummins Engine?
The most important step to diesel engine troubleshooting is identifying the source of your engine complication. You can typically narrow down the possibilities by first documenting exactly what problem you’re facing. By understanding the area that isn’t functioning properly, you can find the most probable diagnosis.
What kind of calibration software does Cummins use?
Cummins has developed a new engine software specific to fire and emergency vehicle calibrations that will be incorporated into our EPA 2013 engines. This new calibration eliminates all emissions related vehicle speed or engine power (torque) derates.

Are there any turbo problems with a Cummins ISX CM871?
If it is buried in soot, and it will be, at 250k+ miles, it is, at the very least, costing you fuel mileage by now, or at its worst, causing turbo problems, power loss, hesitation in the acelerator, and/or excess soot problems. You will get turbo actuator alarms long before you get alarms for this sensor being cloged.
How to remove soot from a Cummins ISX?
<>Determine/Remove the soot buildup in the EGR system: Remove the IMAP sensor from the intake manifold. Very easy to do, takes less than a minute.
When to remove the Doc / DPF from a Cummins?
Removing the DOC/DPF should only be a LAST-RESORT type item when everything else has been done to avoid it, and it is the only thing left, after replacing the injector/sensors with a new ones and force-regening it to determine its actual hpa. <>Determine/Remove the soot buildup in the EGR system: Remove the IMAP sensor from the intake manifold.
