AIR INTAKE ACTUATOR INSPECTION

id074000801500

Caution

• If the lever position exceeds the operation range shown in the figure, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure.

L.H.D.:

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2. Remove the following parts:

(1) Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

(2) Dashboard under cover (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION.)

(3) Passenger-side front scuff plate (See FRONT SCUFF PLATE REMOVAL/INSTALLATION.)

(4) Passenger-side front side trim (See FRONT SIDE TRIM REMOVAL/INSTALLATION.)

(5) Tuner and amp unit (TAU) (With Tuner and amp unit (TAU)) (See TUNER AND AMP UNIT (TAU) REMOVAL/INSTALLATION.)

3. Remove the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION.)

4. Apply battery positive voltage and connect the ground to the air intake actuator terminals as indicated in the table below and verify the operation condition.
