6. SENSORS AND ACTUATORS
1) Sun Sensor
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.
▶ Inspection
- Remove the sun sensor and measure the current between terminals under sunlight.
- Measure the current again under shade. It is in normal conditions if the measured value
is less than the measured value under sunlight.
- Turn the ignition switch to "ON" position.
- Measure the voltage to the sun sensor from FATC connector. (approx. 2.5 V under
sunlight and 4.8 V under shade.)
- 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.
