OBDII Reader won't read !

OK, so I finally got my Exuus Innova reader from Ebay. It sure looks new! Sealed when it arrived. I tried using it on my '98 V70, which recently had the Code 611, but has since been fixed by the dealer - they claim it's the gas cap.

Anyway, everything is running fine on the V70, but I just wanted to see how this OBDII reader works. But for some reason, the yellow warning light keeps coming up and a host of monitors cannot be read. All it does is to try every 15 secs. and I see the blinking yellow light on the reader. I tried it too with engine running, and same results.

I tried it on my '98 S70, and I got a green light. Everything passed!

What could be the reason for it not reading diagnosis from my V70 ?
