Looks like it's data. Has a 12v source you could check voltage going in. A scanner like a tech2 could show what the bcm is seeing. The dic is either bad or the bcm is commanding those values. Any codes or weird lights coming on? Example abs or random dummy lights? Because at those voltages the car won't run. It actually be likely to see several bad modules caused by such a spike.
I'd put money on a bad DIC but if the bcm is bad (which if it were you should see other weird things happening as well like no power door locks or lighting issues etc) Can you communicate with the bcm?.

Edit that's for an 04. Let me check 05.. Okay Diagram shows the wiring is the same for the different years.
