    Check for a blown fuse under the dash.
    My 01 has done it twice. Not sure why, but both times it's been a blown fuse.

    Ah ha!
    You just nailed why mine blew the fuse. Had a power inverter in the cigarette lighter that all of a sudden stopped working, found the blown fuse 2 days later while trying to check for codes.
    Now I know why it blew. I was worried that I had an electrical bug.
