Plasmacluster™ ion generation function, which generates ions inactivating bacteria and supplies to the pas-
senger compartment through air blown from air conditioner, has been adopted.
Airborne mold and bacteria in the passenger compartment are inactivated by the effect of Plasmacluster
™
ion.
Plasmacluster
™ ion generation function is switched between 2 operation modes (clean mode and ion control
mode) automatically, and maintain the ion balance in the passenger compartment close to that in nature.
The operating condition is displayed in the “ION” indicator in the display.
NOTE:
Plasmacluster
™ ion technology developed by Sharp Corporation is installed in this item.
Plasmacluster
™ is a trademark of Sharp Corporation.
OPERATION DESCRIPTION
The Plasmacluster™ ion generation function operates synchronized with the blower motor. The Plasmaclus-
ter
™ ion generation function operates when the blower motor operates.
2 ion generation modes (clean mode and ion control mode) are switched every 15 minutes while blower
motor turns ON with ignition switch ON.
When the clean switch is turned ON, Plasmacluster
™ ion generation function extends the operation time of
the clean mode to approximately 30 minutes for deactivating impurities more actively.
NOTE:
When the clean switch is not ON
Ignition switch: OFF
Blower motor: OFF
Mode position: Defroster (DEF)
Ambient temperature: At about 0°C (32°F) or below [Reactivate at about 2°C (36°F) or above]
When the gas sensor is malfunctioning
When the blower motor is stopped, the Plasmacluster
™ ion generation function also stops operating
(“CLEAN” and “ION” indicators are OFF).

The mode door is automatically controlled by the temperature setting, ambient temperature, in-vehicle temper-
ature, intake temperature and amount of sunload.
SYSTEM OPERATION
The A/C auto amp. receives data from each of the sensors.
The A/C auto amp. sends the air mix door, the mode door and the intake door opening angle data to the air
mix door motor LCUs, the mode door motor LCU and the intake door motor LCU.
The air mix door motors, the mode door motor and the intake door motor read their respective signals
according to the address signal. Opening angle indication signals received from the A/C auto amp. and each
of the motor position sensors are compared by the LCUs in each door motor with the existing decision and
opening angles.
Next, HOT/COLD, DEF/VENT, OPEN/SHUT or FRE/REC operations is selected. The newly selected data is
returned to the A/C auto amp.

Mode position can be selected manually by pressing the MODE
switch or the DEF switch on the A/C control. This the setting of a
mode position. Pressing the AUTO switch allows automatic control
by the A/C auto amp. During the automatic control of a mode posi-
tion, a mode door position (VENT, B/L, FOOT, or D/F) is selected
based on a target the air mix door opening angle and sunload
depending on the temperature calculated by the A/C auto amp. In
addition, the D/F is selected to prevent windshield fogging only when
ambient temperature is extremely low with mode position the FOOT.

AIR MIX DOOR CONTROL SYSTEM
When ignition switch is ON, the A/C auto amp. continuously and
automatically controls temperatures regardless of air conditioner
operational condition. When setting a target temperature with the
temperature control dial, the A/C auto amp. corrects the set temper-
ature and decides a target air mix door opening angle. The A/C auto
amp. controls air mix door according to the target air mix door open-
ing angle and current air mix door opening angle, keeping an opti-
mum air mix door opening angle. When the temperature is set at
18°C (60°F), air mix door is set on full cold, and when the tempera-
ture is set at 32°C (90°F), it is set to full hot.
