COMMUNICATION BREAKDOWN!! DRIVE ME INSANE!!

[Imp558]

...It's not really driving me insane, I just couldn't pass up the Led Zep reference.

 

The 2001 Monte doesn't appear to want to communicate class II data. There's power and ground on the DLC I'm assuming because it powered up 2 scan tools.

Before I rifle through the car and try to find an open spot in the wire from the PCM can anybody tell me if this is a common second gen thing with a simple fix?

Definitely not common. Factory radio in there? Does the Message Center on the gauge cluster work?

Aftermarket stereo, the message center works but I don't want to start the car until I have to so I don't know if it's showing anything pcm related. It's talking about traction control.
