Check solar sensor.
PREPARATION:
Remove solar sensor.
CHECK:
(a)
Cover the sensor with a cloth.
(b)
Measure resistance between terminals 1 and 2 of solar
sensor connector.
HINT:
Connect positive (+) lead of ohmmeter to terminal 1 and nega-
tive (-) lead to terminal 2 of the solar sensor.
OK:
Resistance :
∞ Ω
(no continuity)
PREPARATION:
(a)
Remove the cloth from the solar sensor and subject the
sensor to electric light.
(b)
Measure resistance.
OK:
Resistance : Approx. 4 k
Ω
(continuity)
HINT:
As the electric light is moved away from the sensor, the resis-
tance increases.
NG
Replace solar sensor.
OK
3
Check harness and connector between A/C control assembly and solar sensor
(See page
).
NG
Repair or replace harness or connector.
OK
Check and replace A/C control assembly.
