I finally got to check the voltage and the connections of the wires to the DLC. The purple wire (data) actually was loose and I was not able to remove it from the housing. The wire doesn't have any power, whereas wire 16 is getting 12V. Is the next step going to be removing the wire for pin 11?

Thanks for that diagram. I have looked in the housing and that is how it seems to be set up. Is it possible that the wire on the other side of pin 7 could be shorting out? The car used to connect, though sporadically and the reader had to be pressed really hard onto the housing to get it to read, and now it won't read at all which makes me think it is a short of some kind.

I will have to double check today, but for some reason I do think that pin 7 had 12V of power and I don't remember about 15. It is a 2005 Legacy 2.5i no turbo.

It is just a standard OBDII reader. I have tried several other mechanics readers, as well, and none of them will connect either.

Thanks for the quick reply. The scanner actually does power up as soon as it is plugged in. I have checked the housing for pins that may have been pushed in and found none, but I didn't think to remove the housing and check the wires. I looked up a diagram and I believe pin 7 is for data transfer; this pin does in fact have power but I didn't think to check the wire. Could that be the culprit?

As stated in the title, I have a 2005 Legacy that I cannot get to link up with my OBDII reader. This has been an issue for probably 6 months or more and no check engine light as of now. I am coming up on having to have emissions tests run on my car and I cannot get it to pass if I cannot get the tool to link. I have tried many online suggestions such as checking the cigarette lighter fuse, pulling the battery and letting the computer "reset", and checking all of the fuses inside the cabin and under the hood. Am I missing something here? The OBDII tool does get power so I guess the housing with the computer isn't completely dead. Any suggestions would be greatly appreciated.
