id0740a2801500

With Mechanical Lock Type Air Intake Actuator

L.H.D.:

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

2. Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

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

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.

With Potentiometer Type Air Intake Actuator

L.H.D.:

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.

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

2. Remove the glove compartment. (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

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

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.
