Hi guys, I had a code pop up today on one of our machines, dreaded regeneration. I have an active light with the code 3251-3. Aftertreatment #1DPF trap differential pressure voltage above normal. I don't even know where to start.

    I just had this code come on yesterday. Cat 257D. Can I operate my machine awhile until I can get it repaired? Or stop until it's cleared (repaired)? Kevin

    See the attachments in post #2 above. If the Code is not cleared in short order the engine will derate.
