SERVICE LIGHTS

Best guess. If you have the handling package? The problem may be in the shockes. The orginal equipment had sensors. Attached to the brake system. Which will throw a code to the light. Each shock had a motor that control the suspension. On each coner of the car. For what ever setting you selected. Not a good design. The repair is costly. Because Bilsten doesn't Make the shocks anymore. But you could disconnect the battery. And see if it clears the fault codes. If not look on line for a replacement. Good Luck
