COMPONENT DESCRIPTION
Sunload Sensor
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 averages 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:
When performing the diagnosis indoors, light the sunload sensor with a lamp (60W or more).
DTC CONFIRMATION PROCEDURE
1.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT
NOTE:
When performing the diagnosis indoors, light the sunload sensor with a lamp (60W or more).
Diagnosis Procedure
1.CHECK SUNLOAD SENSOR POWER SUPPLY
1 - Ground: Approx. 5V
2.CHECK CONTINUITY BETWEEN SUNLOAD SENSOR AND A/C AUTO AMP.
2 - 37: Continuity should exist.
3.CHECK SUNLOAD SENSOR
4.CHECK CONTINUITY BETWEEN SUNLOAD SENSOR AND A/C AUTO AMP.
1 - 15: Continuity should exist.
1 - Ground: Continuity should not exist.
Component Inspection
1.CHECK SUNLOAD SENSOR
NOTE: Select a place in direct sunlight when checking sunload sensor.
