Description
The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and controls the air conditioning auto mode. The output voltage from the solar sensor varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases.
The air conditioning amplifier detects changes in the output voltage from the solar sensor.

Inspection procedure
Ok: the display is as specified in the normal condition column.
Standard resistance
Notice:
The connection procedure for using a digital tester such as an electrical tester is shown above. When using an analog tester, connect the positive (+) lead to terminal 2 and the negative (-) lead to terminal 1 of the solar sensor.
Hint:

Problem symptoms table (2006/01- )
Hint:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms are
listed in order of probability in the "suspected area" column
of the table. Check each symptom by checking the suspected
areas in the order they are listed. Replace p ...
Check and replace ecu
Notice:
The connector should not be disconnected from
the ecu. Perform the inspection from the
backside of the connector on the wire harness
side.
When no measuring condition is specified,
perform the inspection with the engine stopped
and the ignition switch on.
Check that the con ...
