By Stability system, do you mean the StabilTrac system ? If so the StabilTrac is more to do with traction than the shocks. The StabilTrac system takes readings from the steering wheel position sensor as well as the ABS sensors for each independent wheel, and when it detects the vehicle "turning" via the wheel speed sensors but the steering wheel sensor is at the 0° meaning the steering wheel is not turning, most likely the vehicle is skidding. It will then apply braking appropriately to the wheels that will best control / stop the skid. You could possibly have an ABS wheel sensor problem or it could be as retarded as my Avalanche was about 6 months ago when it displayed the "Service StabilTrac system" message. When I had it scanned, the sensor that caused the code was the steering wheel position sensor. They cleared the code to see if it would come back and so far it has not.
