(2) Remove the stepper motor.
(3) Connect the special tool (test harness) to the idle air control motor connector.
(4) Connect the positive (+) terminal of a power supply (approx. 6 V) to the white clip and the green clip.
(5) With the idle air control motor as shown in the illustration, connect the negative (-) terminal of the power supply to each clip as described in the
following steps, and check whether or not a vibrating feeling (a feeling of very slight vibration of the stepper motor) is generated as a result of the
activation of the stepper motor.
1) Connect the negative (-) terminal of the power supply to the red and black clip.
2) Connect the negative (-) terminal of the power supply to the blue and black clip.
3) Connect the negative (-) terminal of the power supply to the blue and yellow clip.
4) Connect the negative (-) terminal of the power supply to the red and yellow clip.
5) Connect the negative (-) terminal of the power supply to the red and black clip.
6) Repeat the tests in sequence from (5) to (1).
(6) If, as a result of these tests, vibration is detected, the stepper motor can be considered to be normal.
