 Try putting the steering wheel on full lock and then reverse slowly on concrete or tarmac.  If the VC is locked the engine should stall or at least be heavily laboured like the handbrake is on.
If the VC is Ok there should be just a little load on the engine.  When doing this, the front wheels turn at a different speed than the rears which the VC detects and starts to bind but not lock up - hence the little bit of load on the engine as there is just a little windup.
Cheers
