tool is not that expensive, could have paid for itself with just this one call. it could be a lot of things, you need to get a tool to see what mode the car is in when it is shut down. without it, you are really are going to go insane. :} if you can't spend the 1500 bucks for the ECI Tool, you can purchase a two technology hand held unit for about 400 bucks, works just as well, just need to program the comm settings, and wire up a cable. Only problem with the cheaper tool is you have to use a cheat sheet, to access the menus, but it really is not to bad.
