At this point, I'm not even sure it's a CAN issue. The DME is just not there. I did, however, see one pin that seemed to have zero or little tension on it when I was feeding a wire in to knock out some corrosion. I'm going to try and unpin that socket and see if it looks like it could be messed up in some way.

I used a small diameter needle pin from a test probe to test the compression from each pin as it was removed. if there's a few sockets with not enough drag you should take out the sockets and push the retainer down with a knife blade. The last post in my egs signal disturbed thread I had some photos explaining the process.

There's also some electrical cleaner called deoxit and it reacts with the corrosion to evaporate it into a gas.
