I can not read my OBDII using an actron code reader. I know it works for all my other cars, but for some reason, it's not linking to the obdII on my 05 s60. Anyone else experience this? The ignition is set to on. This is my fist attempt in reading the codes on my volvo, but have used it several hundred times in other cars with no problems.

 

I have an Actron reader and it always worked when I had my S60 and my sons 850. Don't know why yours isn't connecting.
