engine fail safe is where there is an issue electrically with the engine but the computer will put it in that mode so you can limp to a mechanic or figure it out! i love the damn thing! my ecu went to **** and fail safe let me drive around under 40 to get it to the dealership! but unltimantly it is so you arent stuck wherever you are when an electrical part goes out!
