I bought a Roadi RDT40 obd 2 scanner from Amazon. . .
It works with my '05 Impreza but not with the '00 Forester. On the Forester it just runs through the scan protocols and then tells me I have a link error. Of course the Forester is the car I need it for. . .
Any ideas? I know the port works because it's been used before at the dealer and Sunrise automotive. Is there something different about the older Subarus?
