4.CHECK INTAKE AIR
1. Press the REC switch. REC indicator is turned ON.
2. Press the FRE switch. FRE indicator is turned ON.
3. Listen for the intake door position change. (Slight change of blower sound can be heard.)
NOTE:
Confirm that the compressor clutch is engaged (sound or visual inspection) and the intake door position is at
the FRE when the DEF is selected.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Intake door system malfunction: HAC-189, "
Diagnosis Procedure".
5.CHECK A/C SWITCH
1. Press the A/C switch.
2. The A/C switch indicator is turned ON.
Confirm that the compressor clutch engages (sound or visual inspection).
Is the inspection result normal?
YES >> GO TO 6.
NO >> Magnet clutch system malfunction: HAC-197, "
Diagnosis Procedure".
6.CHECK WITH TEMPERATURE SETTING LOWERED
1. Operate the compressor.
2. Operate the temperature control dial (driver side) and lower the temperature setting to 18°C (60°F).
3. Check that the cool air blows from the outlets.
Is the inspection result normal?
YES >> GO TO 7.
NO >> Insufficient cooling: HAC-228, "
Inspection procedure".
7.CHECK WITH TEMPERATURE SETTING RAISED
1. Operate the temperature control dial (driver side) and raise the temperature setting to 32°C (90°F) after
warming up the engine.
2. Check that the warm air blows from the outlets.
Is the inspection result normal?
YES >> GO TO 8.
NO >> Insufficient heating: HAC-231, "
Inspection procedure".
8.CHECK LEFT AND RIGHT VENTILATION TEMPERATURE SEPARATELY CONTROL SYSTEM FUNC-
TION
1. Press the DUAL switch, and then check that “DUAL” is shown on the display.
2. Operate the temperature control dial (driver side). Check that the discharge air temperature (driver side)

DescriptionINFOID:0000000003884756
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor (1) is located on the driver’s side speaker
grille.
It detects sunload entering through windshield by means of a
photo diode. The sensor converts the sunload into a current value
which is then input into the A/C auto amp.
Sunload Sensor Circuit
SUNLOAD INPUT PROCESS
The A/C auto amp. also equips a processing circuit which averages the variations in detected sunload over a
period of time. This prevents drastic swings in the air temperature control system operation due to small or
quick variations in detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor varies whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the air temperature control system operation. On the
other hand, shortly after entering a long tunnel, the system recognizes the change in sunload, and the system
reacts accordingly.

NOTE:
If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to HAC-

Sunload sensor may register a malfunction when indoors, at dusk, or at other times when light is insufficient.
When performing the diagnosis indoors, light the sunload sensor with a lamp (60 W or more).

YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK SIGNAL FOR INTAKE DOOR MOTOR
Confirm A/C LAN signal between intake door motor harness connector and ground using an oscilloscope.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK INTAKE DOOR MOTOR GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect intake door motor connector.
3. Check continuity between intake door motor harness connector and ground.
