Hello, you'll really have to get a hold of the management of the shop you are working with to ask this question so you can understand better. From a technical point of view, not knowing. a single thing about what your concerns are with your Corolla in the first place -- I could not even begin to speculate. If you had some kind of concern with getting power to the fuel pump system, perhaps this leads to a fuse box issue? No idea. Good luck - check with the management of the shop.
