(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.

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

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
<008a00960095009b0099009600930093008c0099004700880095008b0047009b008f008c0047008b009c008a009b0047009b008c00940097008c00990088009b009c0099008c0047009a008c0095009a009600990047004f009a0097008c008a0090008d00

If the voltage cannot be measured, check the wiring for open circuit. If the result is as specified,
replace the FATC controller. A.

(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.
