    EGR on Hellcat getting it to read???

    Hello,
    I do not know which engine diagnostics need to be turned on so that the vehicle will put the EGR in ready mode. Right now, I have a grey forward slash symbol on a reader. I need for it to get to that X symbol.
    Can anyone please provide a list of engine diagnostics that need to be turned on so that I can get the EGR in ready mode?
    Thanks

    Didn't think they even had EGR from the factory.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Well silly me. So I have been trying to activate something that will never activate.

    I have seven variables that are activated.

    Thanks

    On the hellcat forum, they stated it needs to have that "x" in there which will turn green when in the ready mode. Mine has the forward slash as the diagnostics have been messed with. That is not doable in a smog check. I will have to pull up a stock tune to redo the entire engine diagnostics on my tune. It sucks as that takes a long time. But it needs to be done. You are correct as it does not have your typical EGR system on a hellcat.
