    Do You Have No Power to OBD II port?

    I know this is all over the forums but I figured I would post a reminder. I went to have my vehicle inspected this morning and the shop told me there was no power to the OBD II so it could not connet to the DMV. When he told me that I remembered that the cig lighter was not working either. The cig lighter and OBD II port are on the same 20amp fuse. Replace that under hood fuse and you are good to go. Happy motoring.
