(5) Step 5
In this step, the system checks the temperature sensors used to control the A/C. To enter this
step, turn the temperature dial to the right in the step 4. The ambient temperature appears on the
display first and the interior temperature appears next and the intake air temperature last. The
display changes the temperature value each time the defroster switch is pressed.

(7) How to end self-diagnosis
Turn the AUTO switch ON or turn OFF the ignition key.
(8) When A/C system is faulty (Initial auto-diagnosis)
The fault code for the faulty sensor is not displayed. Therefore you should start the self-diagnosis
to check the system.

3) Trouble Diagnosis
(1) Duct Temperature Sensor
If the fault code for the duct temperature sensor (DTC 3) appears on the display, check the sensor
as follows:
Remove the duct temperature sensor and measure the resistance between the terminals of the
<008a009600950095008c008a009b009600990047004f009a0097008c008a0090008d0090008a0088009b0090009600950061004700880097009700990096009f0055004700590055005900470092007e00470088009b00470059005c0b4500500055004700
70008d0047009b008f008c00470099008c009a0090009a009b>ance value is extremely high or
low, replace the duct temperature sensor.
If the result is not as specified, replace the duct temperature sensor. If the result is as
specified, proceed to the next step.
Turn the ignition switch to ON position and measure the voltage between the connector of the
FATC controller and the duct temperature sensor (specification: approx. 2 V at 25℃).
If the voltage cannot be measured, check the wiring for open circuit. If the result is as
specified, replace the FATC controller. A.

D.
(2) Power Transistor
If the fault code for the power transistor (DTC 6) is displayed, check as follows:
Turn the ignition switch to ON position.
Measure the voltage between the terminals of the blower motor while changing the fan speed
from the lowest level to the highest level.
The specified voltage value in each stage: A.
B.
C.
If the voltage is out of specified value, check the wiring for open circuit. If the wiring is intact,
replace the power transistor. D.
(3) Thermo AMP Sensor (Intake Air Sensor)
If the A/C is not turned on, check as follows:
Remove the thermo AMP and measure the voltage between the terminals no. 1 and 2 of the
connector.
Check if the voltage is approx. 12 V when the output is ON and 0 V when the output is OFF.
If the voltage value is not as specified, replace the thermo AMP. If the value is as specified,
proceed to the next step.
Turn the ignition switch to ON position and turn on the A/C by pressing the A/C button. And
measure the voltage between the terminals A12 and A11 of the FATC controller connector
(specification: approx. 12 V).
If the voltage cannot be measured, check the wiring for open circuit. If the result is not as
specified, replace the thermo AMP. A.

(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.
