3. SENSORS AND
1) Sun Sensor ACTUATORS
It is installed on the upper left end of instrument panel. It is using characteristics that the
amount of current changes according to amount of light on the photosensitive surface. Photo
diode, converts the changes in light intensity into electrical changes, detects the amount of light
coming through windshield and changes it into current and then sends the signal to FATC
controller.
(1) Inspection
1. Remove the sun sensor and measure the current between terminals under sunlight.
2. Measure the current again under shade. It is in normal conditions if the measured value is
less than the measured value under sunlight.
3. Turn the ignition switch to "ON"
4. Measure the voltage to the sun sensor from FATC connector. (approx. 2.5 V under sunlight
and 4.8 V under shade.)
5. If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller.
