Unplug the IAC motor harness connector and the ECM harness connector. Check for an open or short-circuit to ground, between the IAC motor terminal 5 and the ECM terminal 4, and the IAC motor terminal 6 and the ECM terminal 17. If a short or open-circuit is present, repair the harness between the respective terminals.
