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.
