ACTUATOR INSPECTION
Checking the Operation Sound
(1) Check that the operation sound of the stepper motor can
be heard after the ignition is switched ON (but without
starting the motor).
(2) If the operation sound cannot be heard, check the stepper
motor’s activation circuit.If the circuit is normal, it is probable that there is a
malfunction of the stepper motor or of the engine control
module.
Checking the Coil Resistance
(1) Disconnect the idle air control motor connector and con- nect the special tool (Test harness).
(2) Measure the resistance between terminal
@ (white clip of
the special tool) and either terminal
@ (red clip) or terminal
$d;!lue clip) of the connector at the idle air control motor
Standard value: 28-33 &
at
20°C (68°F)
(3) Measure the resistance between terminal @ (green clip of
the special tool) and either terminal
@ (yellow clip) or ter-
minal
@ (black clip) of the connector at the idle air control
motor side.
Standard value: 28-33

ACTUATOR OPERATION CHECK
Disconnect the actuator’s connector and, in the

tester’s indication; replace the actuator assembly if any
abnormal condition is discovered.
