2010 9-5 ABS problem, causes brakes to apply on rear tires.

Differential problem on my 2010 Saab has been pinpointed by myself to one of the two engine
Fusebox fuses for the ABS. I pulled one of the breakers and the differential began working perfectly. Is it the wheel Sensors? How do I check the individual wheels?

That sounds very unusual. Is this a 9-5 with XWD? If not, there shouldn't be a rear differential, right?

I have AWD. I really believe I have a bad speed sensor. I am having the ABS checked right now. I am praying my local mechanic here can diagnose the bad speed sensor. My Saab dealer is three hours away.
