Looks like Bennett needs to fix the code list URL......so it's not a bunch of greek on a page.....
Anyways, if you couldn't pull the code with the key on-off method, and you're in the states, take it to any Autozone...they will read the code (but not erase it) for free. If you are out of the U.S., check with your local auto parts stores....many of them will also read it for free.
If you did/do get the code, and need any help diagnosing what might be wrong, dont hesitate to ask. I'm trying to put together some write-ups in the How To section as people are starting to get more and more CEL's for various issues.
