From the looks of it need to code it to the car, shouldnt have all those ? Marks in there. Alignment doesnt have much say and any shop that says they need to calibrate something is full of crap. Seems like it has been repaced- in the first pic at bottom it says if lws is new and says yes.

Thinking you need to code it and if all is working properly turn wheel all the way to left and right and dsc light will disappear also.

Whenever i get something like that doing the turn wheel all way to left/right recalibrates it. Usually happens after a dead battery i needed to do it once this winter.
