A test you could try for verifying that VSC is working (or not) is to take your car to a large empty parking lot on a day when it is snowy/icy/raining and drive it vigorously in a circle until it spins out. If the VSC is working you will first see the flashing VSC light and when you are about to lose control you will hear a sharp beep-beep-beep alarm as VSC takes control of the throttle and braking.

On my similar 2000 LS400, traction control allows quite a bit of wheel spin.
