or if you want to be cheap like me you can use a voltmeter (old needle ones work bettter but digital ones also work) in your front left (passenger side) right behind the ARC (the black plastic coverint the top of the shock) there is a EEC test and an ARC test place - you have to make a wire that goes from one pin to the other, putting the computer in test mode - I don't have the pin #'s in front of me - if you have a shop manual it has them in there or someone I'm sure on here can tell you what pins or show you a diagram... then you put a wire from the positive on your engine then I think another one gets a ground and put your volt meter on 2 pins (sorry for the vague procedure its been awhile since I did it my mind's kinda hazy) and it will give you votage jumpsso if it would do one jump, pause, one jump, then pause for like 5 seconds then repeat the same thing that would be a code 11 wich means pass and everything's ok. Or you could put a resistor in with an LED and instead of the voltmeter, it will blink eact time voltage goes through the wires - that's essentally what a code reader does, but you have a connector on it so its alot less hassle... or like Rlong says autozone has one - and they do it for free - the autozoone where I live happens to have a bunch of idoits who work there (no offence to autozone workers) god I hate York...
