Do you have any diagnostic software to monitor voltages and ecms during this? I may have an oem harness diagram I’ll look over the night

Yes all I have is jpro but it doesn't show real time ECM voltages that I know of. That's why I was trying to figure out what pin is battery power for ECM at OEM connector. ECM is due for calibration update as well but I don't think that would cause this issue. Unfortunately I don't have access to cummins insite anymore.
