(2) Apply battery voltage across the terminals.
(3) Check that air flows from port E to F.
If the operation is not as specified, replace the vacuum switch-
ing valve No. 1.
4. INSPECT AIR CLEANER CAP SUB-ASSY
(a) Check the operation.
(1) Cover port C with your finger, then check that the air
flow from port B to A.
(2) Cover port C with your finger, then check that the air
does not flow from port A to B.
(3) Cover ports A and C with your fingers, then apply 60
kPa (450 mmHg, 18 in.Hg) of vacuum to port B.
Check that there is no vacuum change after 1 min-
ute.
If the operation is not as specified, replace the air cleaner cap.

SENSOR INSPECTION FOR AIR CONDITIONING SYSTEM ± AC005-04 December 16, 2004
Page 8 of 12
5. Inspect Solar Sensor.
Four types of solar sensors are used on Lexus vehicles depending on the vehicle
specifications. The inspection procedure for each type of sensor differs from the
others. Select the appropriate inspection procedure from the table below according to
vehicle specifications and perform the inspection.
EQUIPPED WITH AUTOMATIC
LIGHT CONTROL SYSTEMA/C SYSTEM WITH RIGHT/LEFT
INDEPENDENT TEMPERATURE CONTROLINSPECTION
PROCEDURE
NoNoA
NoYesB
YesYesC
YesNoD
Procedure A:
a. Disconnect the solar
sensor connector.
b. Measure the resistance between
terminals 1 and 2 of the solar
sensor under the
following conditions:
Cover the sensor with a cloth
to avoid direct light.
Expose the sensor to light
from a distance of 300 mm
(11.81 in.) or less with an
inspection light.
NOTE:
Terminal 1 of the sensor is always on
the right, when the lock is facing up.
When using an analog tester, connect
the positive (+) lead to terminal 2 and
negative (±) lead to terminal 1 of the
solar sensor.
HINT:
If the light is weak, the sensor may not react. Be sure to use an incandescent light for
an inspection light.
Standard:
