From the drivers pin switch, the wire goes to the ingegrated control unit, which is the fuse relay box behind left side of dash. The drivers door trigger then leaves the ICU and junctions with the lt. green red wire (junction point unknown, I don't have Honda's service manual, which would show me)

The first thing that bothers me is the 10v at the drivers pin. this should be high 11's- low 12's, so because the screw that holds that pin switch in place is the ground circuit for the door pin, are the threads rusted? Try pulling the drivers pin switch out, you will see a little concave around the hole for the screw that contacts the body. Remove the paint from the body around that concave only. Take fine grit sandpaper and clean the contact point for the pin switch and hose it down with WD-40.

At the ICU, the green wire goes into Connector 409 pin # 9 and exits the ICU same connector pin # 8 (wire color is green/red at this point) With the drivers door open (passenger door closed) do we have ground going into the ICU? What about out? What are the voltages?
