    Make the letter B uppercase... this will take you directly to that table (if your calibration contains it).

    If you make the letter lowercase, then the search will take you to each occurrence (each time you press Search) of that table id (it may be mentioned by other tables).

    Where is the "Set the regen min engine temp to the max value (ie: higher than operating temps)"

    I don't find it either.

    Sorry that my write-up is incomplete / inaccurate. When I lost my diesel (and hopes of an LMM lol) I kind of was hoping that people would just pick up where I left off. Many people did post helpful info here though. At the time I started the thread a lot of the stuff was brand new tech and hopefully helpful and informative to some. Now many people know the ins and outs of tuning out the DPF. Perhaps someone can chime in again? Thanks!!!

    This is all you have to do besides set the DPF codes to not report.

    Also in C2001 to C2004 you can raise to 655, but it really doesnt matter.

    I just did another DPF delete and there are a couple codes that will not go away..... I have never ran into this. Codes are p2033 for the EGT sensor 2 high voltage and then p0546 for EGT sensor 1 high voltage and then p2455 for DPF Pressure sensor circuit high voltage. I have never had these problems before so if someone that has and would like to pitch in and help me resolve this it would be great

    Sounds like you have a short to a power wire that is putting to much voltage in the circuit. Check the wiring harness for a rub through, or anything that would make a short.
