Parked DPF regen: When the truck requests DPF regeneration, you press a button on the dash to initiate DPF regeneration. Forced DPF Regen: A forced DPF regen is started by a diagnostic scan tool at the dealer level. It is not necessary for these conditions to be perfectly met because doing so will still result in a regeneration. The system Downloads. Works on vehicles from 2000 onwards (OBD-2&CAN)-domestic and import. Resets the DPF light after the filter has been replaced. Performs forced DPF regeneration. Micromanages the injection rate. Resets ECU when fitting new DPF. Resets EOLYS additive lights. Retrieves/ erases DPF-related codes. Supports all 10 modes of OBDII including 5. Next the DPF traps soot. 6. During some truck operations the exhuast is hot enough to burn off soot while driving with no fuel sprayed through the 9th injector, this process is called Passive Regen. Passive regen is happening any time temperature in the DPF is above 800 deg F. 7. 2019 MEDIUM DUTY VEHICLES BUILT WITH A 6.7L DIESEL ENGINE — DIESEL PARTICULATE FILTER WARRANTY EXTENSION WITH DIAGNOSTIC TROUBLE CODE P2002 SERVICE PROCEDURE 1. Read the Diagnostic Trouble Codes (DTCs), using Integrated Diagnostic Software (IDS). 2. Is DTC P2002 present in the Powertrain Control Module (PCM)? • Yes, Proceed to Step 3. Due to the raised exhaust temperatures on a long journey (temperatures between 350 and 500�C), the procedure occurs slowly and continuously across the catalytic-coated (with platinum) DPF. The catalytic-coated DPF is situated close to the Engine, therefore the exhaust gas temperature is high enough (500�C) to ignite the soot particles. One user from Polan forum, has this value after the regeneration around 2 g/l, for him cleaning of DPF was a solution. But, right now , my collegue has this number after the regeneration around 0.4 g/l, and still has a halfed regeneration distance - around 120km for mazda 6 and we are searching for a solution Pain in the ass I drove 16.2 miles home today from work, Oxford Circus area to Enfield and see my mileage attached, also find my Trip A counter. Something is obviously wrong since you get 16mpg, if the regen is happening less that 250miles, then look in that direction as it is cleaning too often and yes when it starts the regen the miles /g goes down. typically required every 6 to 12 months. An engine emitting excessive PM or experiencing inadequate regeneration will cause a DPF to require more frequent cleaning. Diagnostics should be performed to identify the cause for more frequent cleaning intervals. It is important to avoid excessive PM and ash accumulation in a DPF, so proper maintenance GbVM.
