Traction Control??

I HAVE A 93 PI AND WHEN I START OFF ON WET ROAD OR GRAVEL AND TIRE SPINS A LITTLE I HEAR THIS SOUND LIKE A GENERATOR COMING ON FOR A SECOND. IS THIS SUPPOSE TO HAPPEN? IT SOUNDS LIKE ITS COMING FROM BEHIND MY RADIO. IT SORTA SOUNDS LIKE THE NOISE THAT A AIR RIDE SYSTEM USE TO MAKE IM MY CADDIE? how does this traction control work if it is the noise?

The traction control compares all wheel sensors to see if they are within a specified mph or voltage of each other. When the rear spins faster than the front is moving, the traction control applies the ABS valves to reduce wheel speed until all 4 wheels are within the parameters set by the manufacturer. Then it allows for normal acceleration again. Hope it helps.
