AIRFLOW MODE ACTUATOR INSPECTION [FULL-AUTO AIR CONDITIONER]

id0740a1801700

Actuator inspection

1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

2. Remove the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL [FULL-AUTO AIR CONDITIONER (E)].) (See AIRFLOW MODE ACTUATOR INSTALLATION [FULL-AUTO AIR CONDITIONER (E)].)

3. Connect the mode actuator connector.

4. Connect the negative battery terminal.(See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(E)].)

5. Connect the M-MDS to the DLC-2.

6. Switch the ignition ON (engine off or on).

7. Operate the airflow mode actuator using the simulation function [MODE_ACTAT_MODE] of the dash-electrical supply unit. (See SIMULATION INSPECTION.)(See SIMULATION TABLE [DASH-ELECTRICAL SUPPLY UNIT (E)].)

8. Verify that the mode actuator operation condition is as shown in the figure.

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.

9. If it cannot be operated, replace the mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL [FULL-AUTO AIR CONDITIONER (E)].)(See AIRFLOW MODE ACTUATOR INSTALLATION [FULL-AUTO AIR CONDITIONER (E)].)

Position sensor inspection

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition ON (engine on).

3. Display PID [MODE_ACTAT_POS] using the M-MDS. (See PID/DATA MONITOR INSPECTION.)(See PID/DATA MONITOR TABLE [DASH-ELECTRICAL SUPPLY UNIT (E)].)

4. Operate the mode switch.

5. Verify that the PID value switches according to the mode switch operation.

6. If the PID value does not switch, replace the mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL [FULL-AUTO AIR CONDITIONER (E)].)(See AIRFLOW MODE ACTUATOR INSTALLATION [FULL-AUTO AIR CONDITIONER (E)].)
