2004 Ford Taurus Question: No reading from the OBD-2

The OBD-2 has detected a malfunction, but the scan tool can't get a reading. What may cause this? -
Answer 1
I assume your light is on. if there is no power to the scan tool, there is a fuse that provides power to the obdII connector. it is usually the cigar lighter fuse. if it does have power and cannot communicate then there is a module that is pulling the system to ground and must be diaged by a shop.

Thanks Roy. As you said the fuse to the cigar lighter was out and after replacing it, I was able to get a reading. -
