Actuator inspection

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

2.Remove the airflow mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL [MANUAL AIR CONDITIONER (US)].)(See AIRFLOW MODE ACTUATOR INSTALLATION [MANUAL AIR CONDITIONER (US)].)

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 (US)].)

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

7.If it cannot be operated, replace the mode actuator. (See AIRFLOW MODE ACTUATOR REMOVAL [MANUAL AIR CONDITIONER (US)].)(See AIRFLOW MODE ACTUATOR INSTALLATION [MANUAL AIR CONDITIONER (US)].)

Position sensor inspection

1.Switch the ignition ON (engine 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 (US)].)

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 [MANUAL AIR CONDITIONER (US)].)(See AIRFLOW MODE ACTUATOR INSTALLATION [MANUAL AIR CONDITIONER (US)].)
