AIRFLOW MODE ACTUATOR INSPECTION [FULL-AUTO AIR CONDITIONER]

id0740a1701600

Actuator inspection

1.  Disconnect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

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

3.  Connect the mode actuator connector.

4.  Connect the M-MDS to the DLC-2.

5.  Operate the mode actuator using the simulation function. (See SIMULATION INSPECTION.)(See SIMULATION TABLE [DASH-ELECTRICAL SUPPLY UNIT].)

6.  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.

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

Position sensor inspection

1.  Switch the main power ON (READY on).

2.  Connect the M-MDS to the DLC-2.

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

4.  Operate the mode switch.

5.  Verify that the PID value conforms to the mode switch operation.

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