Forced DPF Regen

Warning

• Do not perform forced DPF regen in a location with poor ventilation. Exhaust gas may cause carbon monoxide poisoning especially in an enclosed location, such as in a garage, indoors, etc.
• Do not perform forced DPF regen in a location where there are flammable materials such as dried grass or paper waste. The temperature of the exhaust gas and the area around the exhaust pipe and muffler become high during the regen. Therefore, if there are flammable materials nearby, a fire may occur. If the vehicle is stopped over a road surface that is painted, the road surface may be discolored.
• In addition, never allow your body to contact the exhaust gas and the area around the exhaust pipe and muffler. Doing so may cause burn injuries.

Regen Condition Requirements

• Engine is at least 165ºF or the needle is in the middle of the coolant gauge
• Set the parking brake
• Manual and Automatic transmissions must be in neutral
• Do not press the brake or accelerator pedals
• Confirm engine jake brake is off as well as cruise control if equipped.
• For the models equipped with PTO switch, be sure to turn the PTO switch off.
• While performing a forced DPF regen, engine noise will vary and engine speed at idle will increase. This does not indicate a malfunction

FAQ

What does a forced regen do?

Forced regeneration is a diagnostic process that builds temperature to burn soot accumulation down to ash within the DPF filter. During this process, the truck’s computer can closely monitor and test multiple portions of the after treatment system. This type of regeneration can only be performed when a diagnostic tool starts the process within the truck’s computer.

What if the fault codes do not go away?

Yes, this can happen! If you have an existing issue or “Active Fault,” you must correct the issue or perform a DPF regen for the code to go inactive.

Will this fix my truck?

The OTR Reset Tool helps avoid problems, aid in resetting parameters, and running a forced regen. However, if you have any component failures related to the aftertreatment system, they will still require repair.

Will a forced regen void my warranty?

Resetting faults, resetting soot levels, and running forced regens will NOT void your warranty.

How often to do a forced regen?

A forced regen can be performed as often as possible. As a general rule of thumb, we recommend once every couple of weeks to ensure that the filters are maintained.
