- Disconnect Idle Air Control (IAC) motor connector. Turn ignition on. Using DRB, actuate IAC motor. Put DRB in voltmeter mode. Using DRB, check voltage on IAC motor connector Gray/Red wire. If voltage stays less than one volt, go to TEST NS-7B.
- If voltage did not stay less than one volt, check voltage on IAC motor connector Brown/White wire. If voltage stays less than one volt, go to TEST NS-7C . If voltage did not stay less than one volt, check voltage on IAC motor connector Violet/Black wire. If voltage stays less than one volt, go to TEST NS-7D .
- If voltage did not stay less than one volt, check voltage on IAC motor connector Yellow/Black wire. If voltage stays less than one volt, go to TEST NS-7E . If voltage did not stay less than one volt, go to next step.
- Turn ignition off. Remove IAC motor from throttle body. Reconnect IAC motor connector. Using DRB, actuate IAC motor. If IAC motor tip moves in and out, go to TEST NS-8A . If IAC motor tip does not move in and out, replace IAC motor. Perform TEST VER-1 .
