AUTOMATIC AIR CONDITIONER SYSTEM
START: Initial compulsory signal is sent to each of the door motors.
ADDRESS: Data sent from the A/C auto amp. is selected according to data-based decisions made by the mode door
motor, the air mix door motors and the intake door motor.
 If the addresses are identical, the opening angle data and error check signals are received by the door motor
LCUs. The LCUs then make the appropriate error decision. If the opening angle data has no error, door con-
trol begins.
 If an error exists, the received data is rejected and the corrected data received. Finally, door control is based
upon the corrected opening angle data.
OPENING ANGLE:
 Data that shows the indicated door opening angle of each door motor.
ERROR CHECK: In this procedure, transmitted and received data is checked for errors. Error data is then compiled. The error
check prevents corrupted data from being used by the mode door motor, the air mix door motors and the
intake door motor. Error data can be related to the following symptoms.
- Malfunction of electrical frequency
- Poor electrical connections
- Signal leakage from transmission lines
- Signal level fluctuation
STOP SIGNAL:
 At the end of each transmission, a stop operation, in-operation, or internal malfunction message is delivered
to the A/C auto amp. This completes one data transmission and control cycle.

 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).

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.

The intake door is automatically controlled by the temperature setting, ambient temperature, in-vehicle tem-
perature, intake temperature, amount of sunload and ON/OFF operation of the compressor.
SYSTEM OPERATION
The intake door control judges intake door position based on the ambient temperature, the intake air tempera-
ture and the in-vehicle temperature. When the DEF or OFF switches are pressed, the A/C auto amp. sets the
intake door to the FRE position.

 Intake door position is basically set to the FRE when the FRE indi-
cator is ON or DEF switch is ON.
 Intake door position is basically set to the REC when the REC indi-
cator is ON.
 The intake door automatic control selects the FRE, the 20% FRE,
or the REC depending on the target air mix door opening angle,
based on in-vehicle temperature, ambient temperature, and sun-
load.
