(4) Sun-load sensor
Remove the sun-load sensor and measure the current between the terminals with the sensor
exposed to direct sunlight.
Measure the current again in the shade. If this value is lower than the measured value in the
sunlight, the sensor is intact.
Turn the ignition switch to the "ON" position.
Measure the voltage between the terminals of the sun sensor at the FATC connector. (approx.
2.5 V under sunlight and approx. 4.8 V under shade)
If the voltage cannot be measured, check the wiring for open circuit. If the result is not as
specified, replace the FATC controller. A.

5. A/C INPUT/OUTPUT DIAGRAM
Below diagram shows the input/output mapping between the components of FATC A/C and A/C
controller briefly.
▶ A/C compressor control by engine ECU
In case of current vehicle models, the system turns ON or OFF the compressor switch according
to the refrigerant pressure, ambient temperature and condenser temperature to protect the
A/C
circuits. However, for the vehicles equipped with DI engine, the engine ECU turns off the
A/C
compressor under below conditions, including those above.
Coolant temperature: 20℃ or less
Coolant temperature: 115℃ or more
For approx. 4 sec. after starting the engine
Engine speed: 650 rpm or less
Engine speed: 4,500 rpm or more
During abrupt acceleration for the vehicle equipped with manual transmission 1.
