7D-18  FATC-HAVC

Sun load Sensor

Sun load sensor is a photo diode that detects lights. Resistance
of diode can be measured as current by using multimeter
according to increasing sun loads.

1. Check current on the circuits between the sun load sensor

and the airconditioner control unit.

2. Turn the ignition switch to ON position and check that voltage

between No. 13a terminal of the sun load sensor and vehicle
ground is 5V.

3. Measure current between No. 13a terminal of the sun load

sensor and No. 11 terminal of the control unit and check it is
as shown in the below graph.

4. If current value is out of specification, replace the sun load

sensor.

FATC-HAVC  7D-19

Fault : intake (recirculation/fresh air) door inoperative

Remove the glove box.

Measure voltage between 6c terminal positive pole (+)
and bo

dy (-).

Measured voltage is 12V.

Check No. 24 fuse (15A) in the box.

Turn the ignitin switch OFF and disconnect harness of
the intake actuator.

Yes

No

Disconnect 3-pin connector of the intake mode
actuator and turn the ignition switch to ON position.

6C

Check that it operates toward each direction after
connecting the battery to the 6C terminal of intake
actuator and ground 6A & 6B to the body.

 Actuator connector

Intake actuator is normal.

Yes

Repair and replace the intake actuator.

No

Check intake actuator linkage and door for
proper operation and repair if necessary.

Disconnect 20-pin connector from the airconditioner
control unit.

Check current between the intake actuator (6A, 6B)
and the airconditioner control unit (6,7).

Is there current?

Yes

Repair open wire between the intake
actuator and the control unit.

No

Replace the good control unit and re-check. If no fault,
replace the control panel.

Fault : air flow does not change toward panel side.

8H

Remove the center panel of the instrument panel.

Measure voltage between 8I terminal positive pole (+)
and body (-).

Measured voltage is 12V.

Check No. 24 fuse (15A) in the fuse box.

Turn the ignition switch OFF and disconnect harness of
the mode actuator.

Yes

No

Disconnect 8-pin connector of the mode actuator and
turn the ignition switch to ON position.

Check that it operates toward each directions when
ground is connected to terminal (8J, 8H, 8F, 8D, 8B) of
the mode actuator alternatively.

Mode actuator

connector

Mode actuator is normal.

Yes

Repair and replace the mode actuator.

No

Check the intake actuator linkage and door
for proper operation and repair if necessary.

Disconnect 20-pin connector from the airconditioner
control unit.

Check current between the mode actuator (8J, 8H, 8F,
8D, 8B) and the airconditioner control unit (11, 12, 13,
14, 15).

Is there current?

Yes

Repair open wire between the mode actuator
and the control unit.

No

Replace the good control unit and re-check. If no fault,
replace the control panel.

TABLE OF CONTENTS

Caution: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise
noted.
