    2014 Ecodiesel 3.0, no communication with ecm after update

    2014 Jeep ecodiesel 3.0 auto

    Connected MPVI2 and followed instructions to perform the initial update. Read the controller but HP only gave me tcm read file. Now I have no comunication with ecm at all and the dash is full of messages from "press clutch to start" to "Service Air suspension" ect.

    I hope the ECM is not bricked. Ive put in a support ticket but i wanted to see if I wasteing time and I should begin looking for another ECM.

    Im running latest beta software and MPVI firmware is updated.

    Any help or advise would be greatly appreciated.

    It doesn't have to be perfect, it just needs to be done in two weeks...
