there are two types of readers... well maybe there are more.. but I know of two... there's the kind with little LEDs and BEEPS and there's the nice ones with LCD displays..
the led ones will flash out the codes, kinda like morse code and beep ... you then have to look up in a book what the codes are and then you're set... these are like 30 bucks at walmart or most parts stores..
then you've got the fancy ones that have LCD displays that display the codes for ya... some of the GOOD ones will have adapers for different manufacturers too... but those can be well past 100 bucks..
