coming home tonight i stopped sorta hard at this stop sign and my atts light came on in my 98 sh, this had happened once before from going around a bend hard , but when i turned the car off the light went out. i know that the fluid needs changed it has 96 k on it and i am pretty sure that the fluid has not been changed. any ideas what it could be? i have no clue i know that the atts system is pretty picky , the car is all stock, everything, any help appreciated
