Another DD15 with multiple faults that are related to regen problems.

SPN 3480 FMI 2 Doser Fuel Line Pressure Low (Possible Doser valve or Doser block issue)

SPN 3719 FMI 0 Soot Level Very High (successful parked regen will clear)

SPN 5443 FMI 16 DPF HC Absorption High (successful regen will make this code go inactive)

DPF Zone 5 (successful regen using the DDDL software will clear this fault code)

In this video, the Doser valve was first cleared of soot blockage. That didn’t work, so the Doser valve was replaced the. Ultimately the Doser block was replaced.

A successful parked regen using the DDDL software did clear the fault codes except for the NOx sensor. That will most likely need to be replaced in order to clear and verify the repairs.

    Is there a way to disable the Detroit assurance on a 21 freightliner. I want the following distance radar disable but with no dash lights. Thanks

    I’m having a problem with the ash content showing zero on the readout, but the truck still wants a regen. Any idea what the problem could be? I’m getting that hydrocarbon absorption warning fault code and nothing else and have already tried running a regen which seemed to have failed.

    Did you replace the doser block with a new one before the regen? Or did you just remove it and did the regen with it off? I’m confused.

    How do you like putting those washers on the outlet side. That sucks. Why wouldn’t they use the horse shoe type? Or u type.

    so once you get the code for high soot level and you do a successful regen are the filters fully clean or should I look into buying new filters?

    Hi I have a 2019 frightliner cascadia with dd 15 with 549.000 miles on it . Problem started today when I engage or disengage the Jake break. It makes a noise like errrrrrr just had the quality control valve changed on it and the connector on the sensor and on the fuel temperature sensor is missing the gray tab that holds the connector in place could that be the reason otherwise without the Jake break the truck is running fine. I have the otr scan Tool no codes Thank you
  • Hello, how can that diagnostic software be gotten. I need one. Thank you

    Question for you buddy, I have a dd15 that will no complete a successful regen. Getting a 3719-0 pulled filter and had baked, but while I perform a park regen I’ll get to around 600 degrees and won’t go over that. Dosing injector is clean, when I start the regen I see that the injector gets to 17% and then goes back to 0% and doesn’t move again. The other guy prior to me installed a new dosing block and egr valve. Any idea what it could be? Something’s causing the injector not to activate witch is causing my temperature issue

    Where can I get the USB hardware cable to connect to the port?
