How long does a truck Regen take?
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.
Can you shut off truck during regen?
Yep, put it in park and let it idle. Soon as you put it in park it disables the Regen.
What does it mean when a truck won’t do a Regen?
*The MIL came on, which didn’t seem like a major concern, I’d have it looked at when I got home. *The Check Engine light came on, uh oh. From what I remember, this means I need to perform a parked regen. The truck refused to do a manual regen. *The Stop Engine light (red light) has come on and the truck absolutely refuses to regen.
When does the stop engine light come on?
You may also see the High Exhaust System Temperature (HEST) light, which simply means what the name indicates. The light should go out when regeneration is complete. The Stop Engine light is your last chance. If you don’t perform the required regeneration as needed, your DPF will become clogged, which will damage your engine.
Why does Regen light flash when truck is parked?
It means that the exhaust is at high temperature due to extra regen speed which occurs when the truck is traveling at low rates or is parked. If this lamp flashes it means that parked regen is in progress and that system temperature is not up to par yet.
When to stop the Regen on a Freightliner?
Any of these will stop the regeneration. The regen has concluded when the engine returns to slow idle, and the DPF light remains out. Remember, exhaust temperature increases during regeneration, so it is essential that this procedure is performed outside and away from flammable or combustible materials.
