    OBDII scanner problem, can not read codes

    Hey guys,

    I've been trying to read the error code that my escalade is giving me, but the scanners I'm trying at autozone and other auto parts stores are not getting any readings. It does not appear that it is getting any power, I checked the connections that go to the port and they all seem to be in tact. No ripped or torn wires.

    I'm sorry if I wasn't able to do a proper forum search, I'm on the road traveling and want to see what's wrong and if I need an emergency shop visit while away.

    Thanks guys,

    Al

    I had the same problem. I found the fuse for the cig. lighter (found a penney had fallen into it) was blown. Apparently the diagnostic connecter get it power from the same circuit.

    Under hood fuse block, replace the cigar lighter fuse.
