VSC didnt kick in...is this normal?

[blue2006]

I have a'06 ltd V8, about 25k miles on it. this weekend we had some snow here in NY, not a lot, but Sunday morning there was maybe an inch on the roads which were unplowed. with no other cars in sight i wanted to have a little fun and get sideways etc. normally the VSC makes this attempt at getting loose difficult, but i like to see how well the system works anyways, just for kicks. I was going slow, and unfortunately i don't recall how fast, and while making a left turn i invoked some spin, fully expecting the VSC to kick in and help straighten me out...but, it never happened and i ended up doing a 180, luckily for me the truck spun completely before hitting the curb, but i was bothered nonetheless...a little later the system began working, so i know its there, but, i'm wondering if there might be a glitch, or if there are certain conditions in which the VSC wont kick in at all...

Depending on how you "initiated" your spin, its possible that the system never saw the amount of speed differential between tires to engage it.

If you get off the gas while going into spin, then system wont help you. Stay on the gas moderately and DRIVE where you want to go.
