FATC SYSTEM CHARACTERISTIC
Display Performance Enhancement
It allows VFD (Vacuum Fluorescent Display) to develop
the effect of the visible.
Airflow Control Enhancement
It allows MICOM to control the temperature and perform
the control automatically of the heating operation, the
cooling operation and the Mild operation. Also, MICOM
enable to control the amount of the airflow and the
direction of the vent outlet in order to keep the inside
air fresh.
Self-Diagnostic Circuit Check
The full automatic temperature control (FATC) air
conditioning controller contains a self-diagnosis
function to aid in finding any problem with the system.
If the FATC detects some errors it will blink the
temperature display screen for 5 seconds when the
ignition switch is ON.
To enter the diagnostic mode, perform the following
procedure.
1. Turn the ignition switch ON.
2. Set the temperature control to 26 °C (79 °F).
3. Within 3 seconds, push the AUTO and the OFF
switches simultaneously, more than three times.
4. Check the diagnostic trouble code (DTC) in the
temperature indicator screen blinks. If there are no
diagnostic trouble code (DTC) set, the screen will
display 00.
5. When the FATC controller indicates a DTC, proceed
to the table for the DTC.
6. Push the OFF switch to return the controller to its
normal function.
DTC
0 Normal (No Error)
1 Inside Air Temperature Sensor Error
2 Ambient Air Temperature Sensor
3 Error
4 Coolant Temperature Sensor Error
5 Air Mix Door Error
6 Sun Sensor Error
7 Power Transistor Error
Action Taken When the Faulty Occurred
When any faulty is occurred in the automatic
temperature control system, it's sign is informed to
the driver by flashing the set temperature display for
5 seconds at initial starting.

AUTOMATIC CONTROL HVAC SYSTEM 7D-5
How to Verify Faulty Code
When the temperature is set to 26 °C and then within 3
second, push the AMB switch and the OFF switch
simultaneously at three times, the FATC controller
temperature display indicates the faulty code after
performing the self-diagnosis by MICOM.
Condition For Clearing the Faulty Code
1. When the vehicle restarts
2. When push the OFF switch after indicating the faulty
code
3. When pass over 32 seconds after indicating the
faulty code
Fault Safety Function
FATC air conditioner not only performs self-diagnosis
but also has safety function against faults. If there is
open or short in the sensors or potentiometer of
temperature door some specific value will be
substitute.
