OBD Port Link Error

My code reader is giving a link error when trying to read codes. Re-inserted it multiple times thinking it might not be making good contact.
I checked fuse 14 on interior fuse block and it's good.
I am almost certain my code reader is good since used it on a friend's car a few days ago and it worked.
Looking for advice on what else might be the cause of the link error.
It's a 2012 Regal 2.0 Turbo.

Thank you.

I haven't checked it with a voltmeter.
Wouldn't the pin have battery voltage if the code reader is powering on when I plug it into the port? Or does the code reader get it's power activation from a different pin?

Voltage on pin 16 is 12.67.

I would spray both sides of the plug with contact cleaner. I've had issues before where grease/dirt/etc. got jammed in the receiving side of plug...

As it's possible check the OBD port ground. Another option to consider and confirm it's the vehicle is check it with another reader, most parts stores can do it. If you Google "OBD 2 port link error trouble shooting" there's addtional descriptions and methods on checking it.
