the condenser is integrated with the receiver dryer so it is the sub cool type of which
performance is superior to the conventional one the apt sensor for detecting refrigerant pressure
is installed at the high pressure pipeline linking between condenser and evaporator
this is made of semiconductor piezo element and has the proportional characteristics in
which the output voltage is increased as the coolant pressure is increased
hvac heating ventilation air conditioning installed at the center of instrument panel
is the semicenter mounting type let's study about main sensor and actuator relating to the
fatc control in brief the ambient air temperature sensor detecting the external air temperature
and the aqs sensor detecting the contamination of external air
are installed at the center supporter frame at rear side of front bumper
an in-car sensor for detecting the temperature of cabin is applied and installed at the right lower
part of fatc control unit the coolant temperature sensor is installed at the coolant pipe of the
heater core and is used as the input signal for controlling the heating operation of fatc control
photo sensor is installed at the center of instrument panel
as fatc control unit has the communication function
with scan tools using scan tools the diagnosis trouble code the current data
and the actuation test can be performed
ptc positive temperature coefficient heater is applied to diesel engine
the relay is located in the engine room
the operating condition is as follows the engine rpm is over 700 the intake air temperature
is less than 5 degrees celsius the coolant temperature is less than 80 degrees celsius
and the battery voltage is over 12.5 volts the ptc heater will work for 90 minutes or more now
let's study how to self-diagnose and how to change the control logic
when pressing the off button of fatc control panel if press the mode button
four times or more within two seconds then the control panel screen is blinking three times
and then self diagnosis is starting if off switch is pressed it will return to auto control
now let's see how to set and release the defrost function at first press the defrost
button to select the air blowing mode to the front windshield glass next press the
air conditioner button and press the intake button five times within three seconds when button signal
is input normally the control panel screen will be blinking at three times and then the
defrost logic is released or recovered if the air conditioning and recirculation air mode are not
work in force at pressing the defrost button the defrost logic is normally released operating the
buttons with the same method the released defrost logic will be recovered then selecting defrost
button the air conditioning is operated and mode is switched to the recirculation air mode in force
next how to change the temperature unit press the auto button and off button at the same time
for three seconds or more then the temp unit is changed to centigrade or fahrenheit
then as to rear air conditioning system the rear air conditioner is operated by the communication
signal of the front air conditioner module and it can be controlled independently
when auxiliary switch of the front air conditioner control module is set to r range the blower motor
speed control temperature control and mode control can be adjusted by rear air
conditioner control module at the other position except our range the blower motor speed control
temperature control and mode control are possible by the front air conditioner control module
the rear air conditioner control is installed at the roof of the first and second rows
