    Cannot read codes off 2006 Hummer H2

    Hey guys, trying to do a little diagnostic work on my dads truck. Problem is, I plug my OBDII reader in with ignition on and nothing happens. Says it cannot connect to vehicle. Iv checked fuses and wires but everything is good there. Has a 6.0 vortec v8 and engine light is on as well as service 4WD.
    Any advice on why I may not be able to read the codes or any other ways of retreiving the codes.
    Thanks
    Matt

    No connection for the code reader can frequently be a loss of power at the data link connector - No power to activate the link at the code reader. It could be a fuse. You might consider rechecking the continuity of the associated fuses. Sometimes, just looking at the fuses is not good enough. It is possible for a fuse to lose continuity and not look blown. Either use a test light to test for power on the load side of the fuses by powering up the fuse block or pull the fuses and put an ohm meter on them. The test light method is faster.

    Thanks CTD ill check that. My thought was a loose connection somewhere which still could be the cause but ill check the continuity in the fuses and at the OBD plug itself.

    Most of of the time you have to have the vehicle running if possibly not sure if you did or not.

    Okay so tested the fuses and wires today and everything checked out okay. Turns out the Cig lighter fuse was blown and that what caused the OBD port to not work. Codes now cleared. Thanks again guys
