GM Low Speed Data Wires

I would start with the standard high speed wiring test. 60 ohms at the DLC?
What is the DLC, that’s a new abbreviation to me. Edit: another name for OBD-2 port.

How would one perform this? Is it ad easy as pinning both HS wire coming into the DLC? Please be plain in the description as I’m not familiar with a lot of electric terms or slang.

Search on here for “aeswave”. It will lead you to link I have posted multiple times for explanation of how high speed works and a basic test.
