What does FSM stand for. You ask for help because you have no clue. I thought it would be replacing the entire instrument cluster but that never came up once. I didnt know there was a whole module for it. The owners manual doesnt tell you ****. It tells you about your car. I have read it and the only thing closely related to it is changing the lock and interior light programs. An owners manual isnt gonna tell you how to change a chime in your car
