When the TC light illuminates on the dash and I hear the hum of whatever that is... does that mean its working?

Well, there's also the question, "should it be" working.. are you expecting the TC to work at this time?
 
TC is an extrapolation of ABS work. When a wheel is turning at higher speed, ABS modulator pumps brake fluid to its brake caliper and brakes this wheel. During this braking, TC light is on. In this way is intended to help an open diff, not to loss turn from axle opposite wheel. With relative success... scuse for my spelling errors.
