B2630, B2631 SUNLOAD SENSOR
DescriptionINFOID:0000000003846340
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-
42, "DTC Logic" or HAC-43, "DTC Logic".
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 >> Perform trouble diagnosis for the sunload sensor. Refer to HAC-54, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003846342
1.CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND
1. Disconnect sunload sensor connector.
2. Turn ignition switch ON.
3. Check voltage between sunload sensor harness connector and ground.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND A/C AUTO AMP.
1. Turn ignition switch OFF.
2. Disconnect A/C auto amp. connector.
3. Check continuity between sunload sensor harness connector and A/C auto amp. harness connector.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK SUNLOAD SENSOR
1. Reconnect sunload sensor connector and A/C auto amp. connector.
2. Check sunload sensor. Refer to HAC-55, "
Component Inspection".
Is the inspection result normal?
YES >> Replace A/C auto amp.
NO >> Replace sunload sensor.
4.CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND A/C AUTO AMP.
1. Turn ignition switch OFF.
2. Disconnect A/C auto amp. connector.
3. Check continuity between sunload sensor harness connector and A/C auto amp. harness connector.
