(2) Step 2
The sensors and air mix door are checked for proper operation in this step. When the step 2 is
started, the number "2", which indicates that the system is in the step 2, apprears on the display
and the check for sensors is performed. Once the check is done (for 10 to 20 sec.), the one digit
number between 0 and 8 is added behind "2". "20" means there is no fault code. For the meaning
of the rest of the numbers, refer to the description below.

(3) Step 3
In this step, you can check the position and condition of the air source door and mode door. To
start step 3, turn the temperature control dial lightly toward the right and confirm that the number 3
appears on the display. It takes several tens of seconds to finish the check. If there is no fault
code, "30" is displayed. And if there is a malfunction, the corresponding fault code is added as
described in the step 2.
Turn temperature dial lightly toward
right to enter step 3 1.

In this step, the door position of each actuator, fan speed and operation of the compressor are
checked. To enter this step, turn the temperature dial to the right in the step 3. The number, "41",
appears on the display as soon as the step 4 is started. Press the defroster switch to change the
diagnosis mode.

Below table describes the detailed diagnosis items performed for each number. Check the
corresponding component for proper operation according to the table. The voltage values listed
in the table are the output voltage to operate the blower motor. The higher the voltage, the faster
the fan speed is.

(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.
