Well pin 16 orange wire, is the scan tool hot. Should have 12 volts there all the time. Pin pin is scan tool ground, make sure you ground there. Then pin 5 is communication ground. check your wires and see if you have power and ground. If you do it maybe the scan tool. I know you said the fuse is good, the scan tool is powered off the cig lighter fuse.
