i don't know the exact details, but basically it monitors your car movement and if anything is not right, for example wheel spin, under steer, over steer, it will take the power from your engine, help brake the wheels a bit, to help the car in its position.
try this if you wonder:
1) from stop, floor very hard, it most likely will come into play and reduce wheel spin
2) try to make a sharp right turn at 50mph, you will see it on
3) try to floor hard when you are making a right curve turn. usually the rpm should go up right, but if what you put in is too much and could cause tail spin or so, vsa will act up and take away the power. look at the rpm and you will see that it drops to around 2k only, showing that it prevents your engine from continue to feed power to the wheels.

From what I gather, VSA does these things:
1. If a front wheel begins to lose traction, it cuts off your throttle and applies brakes to the spinning wheel (eg. during acceleration from a stop).
2. Using a yaw sensor, a lateral acceleration sensor, and the steering wheel input sensor, VSA monitors the car during turns. If the car is oversteering or understeering, VSA cuts off the throttle and applies brakes selectively (front left, front right, or both rear) to bring the car back in line.

A good test I like to do once and awhile is when I'm on a wet merge ramp I jerk the wheel to break the front loose. You can feel VSA prevent the front from skidding outward. It's kind of a weird feeling.
Another test is to accelerate hard from a stop around a tight corner when the road is wet. You can definitely feel VSA then. When you turn off VSA the front end will break away and skid outward.

But seriously folks, a quick tip, TURN IT OFF IF YOU'RE EVER GONNA RACE! Unless you are racing on damp roads (obviously straight line only), then it can actually help, depending on how wet it is.
