The reason that you arent getting any communication is because you arent plugging into the controller. The "group box" that youre connecting to is for remote monitoring if Im not mistaken. You must plug into the MTV board inside the controller. Press login, type in the job number and press enter. Press ACTV then Err to view current faults. I believe specific fault codes will not be stored after power down, so you need to view the faults before the car is reset.
