Once you do that you can enter your esn and have access to all the wiring diagrams(cummins not truck manufacturer) and part numbers, service information for that exact engine. You can put the fault codes in and follow the troubleshooting tree to help figure out your problems. I know you said it's not active anymore but I'm curious about fault 1682.

Yes I have it. From what I'm being told I need fords wiring schematic not cummins.

I'm also noticing the def fluid dosing valve commanded position open/close more then I originally thought. Its very fast when it switches from closed to open but this can't be correct. It should stay open when the diesel exhaust fluid dosing state is "dosing "
This is gotta be my issue, but why?
