I am no familiar with the Subaru A.W.D. but on my Jeep the only time the awd is activated is when one wheel begins to loose traction. At this time some break pressure is diverted to that wheel so that another wheel will help. In other words if the subaru has this feature ? removing the fuse will not help you. Ask your dealer how your awd works, get a factory manual, or go to advance or auto zone and purchase a manual on your Subaru and a manual on anti lock breaks. I hope this has helped.
