    Unhappy Grid Heater Delete - 2017 RAM 3500 6.7L Cummins

    I did a grid heater delete on my 2017 Dodge RAM 3500 6.7L Cummins and now I get a CEL.

    I have a tune from DRD with the MM3 Tuner.

    Do I need to have a redo on on my tune so I can eliminate the CEL?

    Thanks Tommy

    If you just start it and don't wait to start the light should stay off.

    Oh boy- I need to look for the thread we had going about this @cumminsdieselfreak @akbob

    Is this a push to start truck?

    Are you waiting to start?

    To answer the OP's question, a retune would kill the CEL but depending on which ignition/starting process you do.

    A lot of people can bypass the light without a retune.

    On my 14 I did some testing with the hot wire off the solenoid but left the coil wires attached and I did not get a cel, and I have the push to start.
