Saab 900NG Non-responsive OBD Port

[AXrescuer]

Hi peeps,

 

Just wondering if any of you may be able to suggest a reason as to why my Saab's OBD port appears to be dead?

No scanners will work when attached to it, even the dealer's own one! They have no idea what might be the cause except to say

that the after-market stereo may be to blame.

 

Any help would be muchly appreciated!

TV2 is the same, and I have never been able to figure out why

Maybe there is a port on the side of the diagnostic port that a tiny machine plugs into to diagnose faults on the diagnostic port?

Yeah it shares the same fuse as the stereo which works fine.

Dunno....

there should be enough power in a diagnostic socket to power a 5 watt side light bulb

connect one side to pin 4 and the other to pin 16 and see if it lights up

Does your deadlocking work?

[AXrescuer]

It's weird. Everything is fine apart from an intermittent CEL. I need to flash off the fault codes otherwise I've no chance of tracing the fault. It's mental!

Are all the contacts in place?

[AXrescuer]

Yep. Everything looks normal in there.
