Check engine light

I know autozone does free diagnostics on check engine lights, but is there a way someone can check by doing something from inside the car to get the trouble codes?

Here is a good web site for pulling codes:http://www.nmia.com/~dgnrg/nissan1.htm.

You can rent the machine at autozone as well. Using a jumper is not a good idea unless you are sure you will do it right. Good luck.

I was wondering would kragen or autozone sell these jumper wires?

Is your car OBDI or OBDII?
