    Single Owner/OP of a 2020 Cascadia...

    Have a professional DDDL P70XXXXX.... license paid for till Jan2025.

    Truck will not let me change the DT-12 into manual shift, need the backdoor password.

    Dealer wants 200/hr to change it.

    I already bought the programming events through Daimler.

    Reach out to me via PM if you can help, nearest dealership is 300 miles away

    Then you bought the truck used. Get with the dealership where you got it. They will have to get with Detroit to have it removed.

    True, true...

    Already got with them...

    Original dealership where I bought, going out of business in Arkansas. Doggett Freightliner fired all the Springdale, AR staff.

    Excel Truck Group is gonna do an overhead and change parameters, for $650.

    Yeah, I tried.

    All logged in into DDL8.19, everything updated, got elevated to level 2 password help where I learned, even though the website says, you can't program certain body modules.

    They don't say you can't update dt-12 on the programming purchase page, but when you get there you can't.

    Off to the dealer is your only choice. Maybe once they do 1 time, I can do it again, but why would I after everything has been fixed.

    Worth a shot seeing if someone one here was dealer level access and wanted to PM about making 100$ tax free.

    If nobody changed previously maybe you can get lucky.. Try 0000 or 1111. 2222 all the way to 9999.
    Or you need someone with the good bootleg and create the new password for you.

    It's password protected just like your email. Not many people know but before you buying the truck make them reset the password for your request.
