Being in the used cars business, right now i am waiting on a computer/part for an ABS problem on a used Volvo...........

        Yes cars have many different computerized brains.......You do not just check the plug, gap/timming and vacume any longer.......

        ALSO................Every car is always hooked up to a computer to see what they heck is the problem.............Most of these computers are hand held and small....................
