(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.
