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
- Diagnostic tool forced regeneration
- Chemical forced regeneration
- Powertrain control (including onboard diagnostic checks)
This function is used to burn off the soot particles in the particle filter. It is particularly useful for cleaning the DPF when the vehicle is always driven in an urban environment.
