DESCRIPTION
The solar sensor, which is installed on the upper side of the instrument
panel, detects sunlight and
controls the air conditioning in AUTO mode. The output voltage from the solar
sensor varies according to
the amount of sunlight. When the sunlight increases, the output voltage
increases. As the sunlight
decreases, the output voltage decreases. The A/C amplifier detects output
voltage from the solar sensor.

INSPECTION PROCEDURE
HINT:
1 READ VALUE OF INTELLIGENT TESTER
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(c) Expose the sensing portion of the solar sensor to light.
HINT: Use an incandescent light for inspection.
(d) Select the item below in the DATA LIST, and read the display on the intelligent tester.
DATA LIST / AIR CONDITIONER:
OK: The display is as specified in the normal condition column.
Result
2 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR)
(a) Disconnect the solar sensor connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage
3 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR - BODY ECU)
(a) Disconnect the body ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE BODY ECU
4 CHECK SOLAR SENSOR
(a) Remove the solar sensor with its connector still connected.
(b) Connect the positive (+) lead from the battery to terminal 6 (CLTB), and the negative (-) lead to terminal 3 (CLTE) of the solar sensor.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage
NOTICE: While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
HINT:
5 CHECK HARNESS AND CONNECTOR (SOLAR SENSOR - A/C AMPLIFIER)
(a) Disconnect the solar sensor connector.
(b) Disconnect the A/C amplifier connector.
