Disconnect the battery and touch the terminals together for 10 seconds and then leave it disconnected for a half hour or so. Otherwise it should clear after a set number of key cycles.

OBD 2 is for anything 1996 and up. I believe the 94 is still OBD 1. It may be OBD 1.5, which is the old style codes with the new style plug.

I believe 94 is OBD 1.5. You'll need an OBD 1 scanner with an OBD II cord, in essence. Any shop with a snap-on scanner should be able to do it. AZ won't...

What code did you get? Just curious.

If you touch the cables together(while disconected) it pulls any possibly stored voltage in the car.
