I found this, which looks like yiuddish to me, but someone might find it interesting.

I believe this is for the Consult protocol used on older Nissans. You can find additional documents on the protocol and the electrical nature of the spec here:

I believe newer Nissan's use OBD-II over CAN for connecting to the 'Consult II' factory tool, but I could be mistaken.
