KOER Question

I'm trying to figure out if I'm doing this right. I've gotten my code which was 111 which is good but I'm not sure If I did this right.I know how too hook it up (obviously) to flash through the Check Engine Light but my question is this.. When I go to scan for the codes (I do it after driving it around and getting to normal operating temps) do I hook up the jumper THEN start it? Or do I start the motor and while it's running, plug it in? I Hooked up the jumper, got in and started it with the jumper connected. Did I do it wrong?

You did it correctly. The jumper must be in place before the engine is started.
