DIAGNOSIS
DIAGNOSIS TEST
FATC airconditioner system has self-diagnosis
function. Turn the ignition switch ON and press intake
switch more than 4 times within 2 seconds while the
AUTO switch is pressed, then it will diagnose incarsensor, ambient sensor, water temperature sensor and
temperature actuator for open/short and will display
numerical fault code on the set temperature display of
VFD.

TROUBLESHOOTING
Check and Service
Incar sensor is a sensor that detects interior air
temperature and a thermistor that decreases its
resistance when temperature up and increases when
temperature down.
1. Check that there are incar sensor fault code (11,12)
by using self-diagnosis function.
2. Disconnect incar sensor 2-pin connector that
installed on inner lower instrument panel cover of
driver’s side and remove the sensor.
3. Check that measured resistance value among
incar sensor terminals is as shown in the right side
graph.
Notice: Measure resistance value by soaking the
sensor in the ice water and check changes in
resistance values after soaking it in the very hot
water.
4. If resistance value is out of specification, replace
the incar sensor.
5. Install the sensor and turn the ignition switch to
ON position and check that voltage between No.
12A terminal of incar sensor and body (-) is 5V.
6. Check current between the No. 12B and 12A
connector terminals of the incar sensor and the No.
1 and 5 connector terminals of the airconditioner
control unit and repair the wire if defective.

Ambient Sensor
Ambient sensor is a sensor that detects ambient
temperature and a thermistor that decreases its
resistance when temperature up and increases when
temperature down.
1. Check that there are ambient sensor fault code
(13,14) by using self-diagnosis function.
2. Disconnect ambient sensor 2-pin connector that
installed on front right side of the frame and
remove the sensor.
3. Check that measured resistance value among
ambient sensor terminals is as shown in the right
side graph.
Notice: Measure resistance value by soaking the
sensor in the ice water and check changes in
resistance values after soaking it in the very hot
water.
4. If resistance value is out of specification, replace
the ambient sensor.
5. Install the sensor and turn the ignition switch to
ON position and check that voltage between No.
10 terminal of the ambient sensor and body (-) is
5V.
6. Check current between the No. 10 and 9 connector
terminals of the ambient sensor and the No. 2 and
5 connector terminals of the airconditioner control
unit and repair the wire if defective.

Water Sensor
Water sensor is a thermistor that detects engine coolant
temperature to operate the blower speed to LO when
water temperature is less than 50.
1. Check that there are water sensor fault code (15,16)
by using self-diagnosis function.
2. Disconnect water sensor 2-pin connector that
installed on the heater unit of inner instrument panel
and remove the water sensor.
3. Check that measured resistance value among
water sensor terminals is as shown in the right
side graph.
Notice: Measure resistance value by soaking the
sensor in the ice water and check changes in
resistance values after soaking it in the very hot
water.
4. If resistance value is out of specification, replace
the water sensor.
5. Install the sensor and turn the ignition switch to
ON position and check that voltage between No.
7a terminal of the water sensor and body (-) is 5V.
6. Check current between the No. 7a and 7b connector
terminals of the water sensor and the No. 3 and 5
connector terminals of the airconditioner control unit
and repair the wire if defective.

Sun load Sensor
Sun load sensor is a photo diode that detects lights.
Resistance of diode can be measured as current by
using multimeter according to increasing sun loads.
1. Check current on the circuits between the sun load
sensor and the airconditioner control unit.
2. Turn the ignition switch to ON position and check
that voltage between No. 13a terminal of the sun
load sensor and vehicle ground is 5V.
3. Measure current between No. 13a terminal of the
sun load sensor and No. 11 terminal of the control
unit and check it is as shown in the below graph.
4. If current value is out of specification, replace the
sun load sensor.

Fault : intake (recirculation/fresh air) door inoperative
Remove the glove box.
Check No. 24 fuse (15A) in the box.
YesNo
Check that it operates toward each direction after
connecting the battery to the 6C terminal of intake
actuator and ground 6A & 6B to the body.
Wiring side connector
Intake actuator is normal.
YesRepair and replace the intake actuator. No
Check intake actuator linkage and door for
proper operation and repair if necessary.Disconnect 20-pin connector from the airconditioner
control unit.
Check current between the intake actuator (6A, 6B)
and the airconditioner control unit (6,7).
Is there current?
YesRepair open wire between the intake actuator
and the control unit. No
Replace the good control unit and re-check. If no
fault, replace the control panel.
Measure voltage between 6c terminal positive pole
(+) and body (-).
Measured voltage is 12V.
Turn the ignitin switch OFF and disconnect harness
of the intake actuator.
Disconnect 3-pin connector of the intake mode
actuator and turn the ignition switch to ON position.
