No CAN Serial Bus communication

I have and 2008 f 250 super duty. I had to change the coolant recovery bottle today. Taking the battery out the wrench shorted across the battery. **** happens!

Now I have no PCM communication no ABS communication no TCM communication and few others. What problem is I have no CAN serial bus communication and I need a wiring diagram to diagnosis it. I've checked the fuses and tested the relays all test good. It's easy to talk about what I can communicate with Instrument cluster is all i have that will respond.

The one schem I did find I can't enlarge it or print it and he hand drew on it so I can't really read what I need to. The Haynes manual I bought too, should have said we have some diagrams, the one you really want isn't in here.

Anybody have one I can print?

Thanks in advance

Update I've checked voltage on CAN-H and CAN-L both are within spec, also I have checked the resistance across both and that is with in spec. Also the voltage on my DLC is a little low (11.8V) but that should be normal given the amount I've had the key on and not running. So without a wiring diagram I am not sure where to start looking, if it is fused in a different location then Power distributions boxes.

What I do know is I have no bare wires to ground.
