DPD/DPF Forced Regeneration & Reset Service

【Work for PACCAR , DITROIT Trucks】

DPF Regeneration is used to clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode (such us high temperature heating conbustion, fuel additive or catalyst reduce PM ignition conbustion) to stabilize the filter perfornance. ​An unmaintained DPF runs your vehicles unnecessarily hard and less efficient. With regular DPF maintenance, you can save lots of dollars and time by getting your DPF cleaned, restore your DPF to nearly new! Increased Fuel Economy up to 5%. Avoid costly replacement of the filters. Lower Overall Maintenance Costs.

DPF regeneration may be performed in the following cases:

(a) The exhaust back pressure sensor is replaced.

​​(b) The PM trap is removed or replaced.

​(c) The fuel additive nozzle is removed or replaced.​

(d) The cataytic oxidizer is removed or replaced.

​(e) The DPF regeneration MIL is on and maintenance is performed.

​​(f) The DPF regeneration control module is replaced.
