Operation Check
1. Remove the throttle body.
2. Remove the idle speed control servo.
3. Connect the special tool (test harness set: MB991709)
to the idle speed control servo connector.
4. Connect the positive (+) terminal of a power supply (approx.
6 V) to the terminals No.2 and No.5.
5. Hold the ISC servo 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 terminals No.1 and No.4.
(2) Connect the negative (–) terminal of the power supply
to the terminals No.3 and No.4.
(3) Connect the negative (–) terminal of the power supply
to the terminals No.3 and No.6.
(4) Connect the negative (–) terminal of the power supply
to the terminals No.1 and No.6.
(5) Connect the negative (–) terminal of the power supply
to the terminals No.1 and No.4.
(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.
