SUNLOAD SENSOR
System Description
INFOID:0000000001547443
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor (1) is located on the instrument upper mask. 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 front air control.
SUNLOAD INPUT PROCESS
The front air control also includes a processing circuit which averages the variations in detected sunload over
a period of time. This prevents drastic swings in the ATC 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 will vary 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 ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
Sunload Sensor Diagnosis Procedure
INFOID:0000000001547442
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted. (25 or
AUTO
25
is indicated on front air control as a result of performing self-diagno-
sis STEP-2.)
1.
CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND
1.
Turn ignition switch OFF.
2.
Disconnect sunload sensor connector M94.
3.
Turn ignition switch ON.
4.
Check voltage between sunload sensor harness connector M94
terminal 1 and ground.
Is the inspection result normal?

INTAKE SENSOR
Component Inspection
INFOID:0000000001572418
COMPONENT DESCRIPTION
Intake Sensor
The intake sensor (1) is located on the A/C unit. It converts tempera-
ture of air after it passes through the evaporator (2) into a resistance
value which is then input to the front air control.
