these things have computers right my friend said i should hook it up and find the codes and stuff. honestly i dont understand how this works can someone explain please, also where do u hook this up to do it? sorry to bother
The computer doesnt need to be hooked up to anything special to run codes. It has a self diagnostic built in. You need to get a Haynes manual or Factory Service Manual would be even better. They will tell you how to run the diagnostic and what the codes mean.
