Find out what the ECU is sending to the IAC 200

Yes.

To do this you must remove the cover over the ECU's plug, slide it back on the cable and run with it plugged in and resting on the floor in front of the passenger's seat.

Ground your meter to the ECU's mounting bracket on the fender wall. Probe carefully on pin 10 and then 23. The numbers are molded into the plastic of the plug next to the holes where the wires attach. #10 should have a white wire and #23 a green/red wire.
