Why does the check ride control light come on when starting a 99 Deville but goes off and stays off when the reset button is pressed until the car is started again?

try disconnecting battery for 10 minutes then reconnecting battery if the fault that put the light on has been fixed the signal is stuck in computer.disconnecting battery will reset computer and take signal away if fault is fixed
