Was reading an article on Wired News this afternoon about a new bill in the states intended to allow consumers and third-party technicians to access (all of) the diagnostic codes for their cars. Headaches are much like the check-engine lights described in the article. They tell you that something is wrong, but there's not much you can do to figure out what in particular is causing the problem short of trial and error.

I guess what I'm saying is I could use the owner's manual for this silly contraption. Though I suppose I'd settle for turning off the light...
