As you can see the OBDII connector on my car has contacts on 4,5,6,7,9,12,16.
Then I thinked it was OBDII ISO compliant. No way! I have tried different ISO based interfaces without any luck.
Whith the advice of kan, http://minilien.com/?B1D9CjVQZl and other doc in my possession I made some investigations on the different contacts. See xls for results. Then I finally decided to short pin 5 & 6. Bingo: MIL flashing a good "12" code. So the car is not ISO but rather ALDL in OBDII connector, I think.

Thanks again to you.

Yes, indeed it's an ALDL in OBDII socket. By the way this diagrams I have posted link to are the same you have got. I haven't any problems with download.
I'v found site with diagrams of interface for GM's OBD I/ALDL and connetor's description. In Nubira there is 16 pin OBD-II style Australian Connector.
