I recently acquired a '03 Grand Prix and I'm looking to flush the brakes. I'd like to cycle the ABS pump to do a complete fluid change. I know the correct way to do this is to use the GM Tech-II scan tool but I'm wondering if its possible to do this using a laptop computer? Seems like there should be some sort of program that will allow you to do this, kinda like engine tuning that people already do through laptops.
