the erg of the shield has to be a part of electronic, mechanical, stopper you can? plug only the mechanics? it serves no why? you bust all the parameters to the control unit and blows out the error, according to me you should exclude it electronically, I would recommend you also take it apart and clean it well in a way stapparla but I think that now is just a waste of time, and if you have damaged the mechanical part after maybe the risks that will remain locked open ? even worse
