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.

DTC DETECTION LOGIC
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).

A/C AUTO AMP.
DescriptionINFOID:0000000003940951
COMPONENT DESCRIPTION
A/C Auto Amp. (Air Conditioner Automatic Amplifier)
The A/C auto amp. (1) has a built-in microcomputer that processes
information sent from various sensors needed for air conditioner
operation. The air mix door motors, the mode door motor, the intake
door motor, the blower motor and the compressor are then con-
trolled.
When the various switches and temperature control dial are oper-
ated, data is input to the A/C auto amp. from the A/C control.
