AIRFLOW MODE ACTUATOR INSPECTION

id074000801700

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. Connect battery positive voltage to terminal D or F and ground to terminal F or D of the airflow mode actuator.
2. Verify that the airflow mode actuator operates as

shown below.

• If there is any malfunction, replace the airflow

mode actuator.

3. Verify that the resistance between the terminals of

the airflow mode actuator is as shown in the
graph.

• If there is any malfunction, replace the airflow

mode actuator.
