I Own a 2002 Grand Am SE1 and I simply went to Advanced Auto Parts. They will let you borrow a diagnostic handheld tool that you will connect to a connector under the drivers side dash. Then bring the tool back inside. They will get a printout with the diagnosis. They will tell you how the tool works. It's easy.

there is no "diagnostic mode" check ALL the fuses xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx If you are referring to the diagnostic connecter being accessed and the light does not come on then you need to check and replace the bulb. If it was a fuse, which would be the ECM, the car would not even run.

Why does my 2000 Pontiac Grand Am, with a 2.4L engine, run rough at idle but runs normally when placed in neutral? I changed the plugs and air filter, but the problem continues.
