I have a 97' legacey outback. cant get the car to reset(disconnected the battery, flashing lights) have went through different reset methods. It is not resetting with the reset button, and i do not have a remote. I've talked to at least ten suby techs, and they all tell me the same thing. If anyone has any info, or tricks on how to reset theese cars, it would be much appriated!!!!!!!!! Thanks, Jeff
