    Completely stock, locked PCM, 2018 Challenger can't read

    Trying to take an initial read to send my pcm in to be unlocked. Reads the vin and vehicle info but when i try to read file it says controller init: failed to start.

    Any suggestions? Brand new MPVI 2, computer reads that its being plugged in, drivers installed for MPVI 2 and newest version of VCM software. Just need to get the initial read off to send it in for unlocking.

    Yep. Ive done a 16 and 17 and spaced it. Got to the back of the car and found a tazer, unplugged it and got her taken care of. Thank you!

    I've read where the module is however I'm not sure what this bypass cable is doing, is it permanent, what are the connection points .. the Gateway Module being the 1st connection point ... what is the 2nd?

    Tks
