what does service stability system mean? on 2005 Chevrolet Uplander

What does it mean when service stability system light comes on?

Asked by for the 2005 Chevrolet Uplander
Sounds like an issue with the stability control feature of the vehicle. Typically - this system in conjunction with the anti-lock brake system -- works to keep the vehicle under control and keep it from spinning out or losing traction.

A good diagnosis first hand would be in order.
