I'm not sure if this helps but a friend was experiencing obd2 port failure with his Saab wagon. He'd installed upgraded software supplied by a vendor and the port would no longer recognize his reader. Uninstalling the third party software and disconnecting the battery reset the obd and his reader now worked and the car passed smog. I don't know if simply disconnecting the battery would help your situation or if it's something software related.
