Home  id0740a2653300

Actuator inspection

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

2.  Remove the rear vent actuator. (See REAR VENT ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

3.  Connect the rear vent 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 rear vent actuator using the simulation function [R_VENT_ACTAT] of the dash-electrical supply unit. (See SIMULATION INSPECTION.)(See SIMULATION INSPECTION.)(See SIMULATION TABLE [DASH-ELECTRICAL SUPPLY UNIT (E)].)

8.  Verify that the rear vent 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 does not operate as shown in the figure, replace the rear vent actuator. (See REAR VENT ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

Position sensor inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine on).

3.  Display PID [R_VENT_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 or DEFROSTER switch.

5.  Verify that the PID value switches according to the MODE switch or DEFROSTER switch operation.

6.  If the PID value does not switch, replace the rear vent actuator. (See REAR VENT ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)
