Probably an easytronic?
Could be a locked shifting mechanism or weak motor.
Just remove it and check if still can move properly.

On my words try to disconnect starter when fid up him from another er source when start engine possible somewhere you get short that under loud voltage when spin starter occurs, or if after reconnect battery tray put some battery checker with starter loud improviser when se what happens possible if somewhere bad contact or minus you ecu again cuts off so if u not get again communication you know that bad minus or feed contacts
