    Minimax Issues Unable To Program ECM

    I have a 2007.5 Dodge Cummins 2500.

    I have s300 turbo stage 2 ATS transmission cold air intake of course AFE power intake fully deleted and I'm having issues with my Minimax programming it on my instrument cluster.

    It says transmission temp light and my tow-haul don't work and there are some weird numbers on my park reverse neutral drive cluster.

    Any help would be great.

    Not 100% sure I understand.

    Was everything working well then I all went funky?

    Were you in the middle of programming?

    A little more detail would help.

    We are likely thinking the same thing- was your voltage alright when programming?

    Disconnect batteries and check voltages.

    If ok, check DTCs, if ok, return to stock and install tune again.

    Also why Mini Maxx won't go past the turn key to run position.
