B2630, B2631 SUNLOAD SENSOR
Description
INFOID: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.

DTC DETECTION LOGIC
NOTE:
• If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to
.
• 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).

B2630, B2631 SUNLOAD SENSOR
DTC CONFIRMATION PROCEDURE
1.
CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT-III
1.
Using CONSULT-III, perform “SELF-DIAGNOSIS RESULTS” of HVAC.
2.
Check if any DTC is displayed in the self-diagnosis results.
NOTE:
• If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to
.
• 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).
Is DTC “B2630” or “B2631” displayed?
YES
>> Perform trouble diagnosis for the sunload sensor. Refer to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000003846342

B2632, B2633 AIR MIX DOOR MOTOR (DRIVER SIDE)
Description
INFOID:0000000003846347
COMPONENT DESCRIPTION
Air Mix Door Motor (Driver Side)
• The air mix door motor (driver side) (1) are attached to the heater
& cooling unit assembly.
• It rotates so that the air mix door is opened or closed to a position
set by the A/C auto amp.
• Motor rotation is then conveyed through a shaft and the air mix
door position feedback is then sent to the A/C auto amp. by PBR
built-in air mix door motor.
