    I did it with another meter one is 1.90 other is 2.10. And I checked the pins C & D in the j1939. it’s about 1 Volt at the J1939 plug!! So there’s an issue somewhere! Not the computer though right?

    With the key off measure between the J1939 pins and a good ground. You should get an infinite or close to it reading. I doubt there is a problem with any of the devices on the data link more likely a wiring problem.

    I'd disconnect the ABS ECU and measure voltage @ DLC again.

    Yea same thing. 1.90 and 2.10 that was with a different meter. Likely more accurate one being snap on I hope.
