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 CONTROL SYSTEM
• 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.

The intake door is automatically controlled by the ambient atmospheric CO and NO
2,
temperature setting,
ambient temperature, in-vehicle temperature, 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 atmospheric CO and NO
2,
ambient
temperature, the intake air temperature and the in-vehicle temperature. When DEF or OFF switches are
pressed, the A/C auto amp. sets the intake door at the FRE position.

Intake Door Control Specification
• Intake door position is basically set to the FRE when the intake
indicator is OFF or DEF switch is ON.
• Intake door position is basically set to the REC when the intake
indicator 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.
Automatic Re-circulation Control System
In addition to the regular automatic control, intake door condition is
controlled by gas sensor output signal when auto recirculation mode
is selected. This system automatically controls the inlet to prevent a
smell of exhaust gas from getting into vehicle by receiving signals
from the gas sensor that detects ambient atmospheric CO and NO
2.

BLOWER MOTOR CONTROL SYSTEM
BLOWER MOTOR CONTROL SYSTEM
System Diagram
INFOID:0000000003884727
System Description
INFOID:0000000003884728
Blower speed is automatically controlled by the temperature setting, ambient temperature, in-vehicle tempera-
ture, intake temperature, amount of sunload and air mix door position.
By pressing the AUTO switch, the blower motor starts to gradually increase air flow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flow-
ing.
SYSTEM OPERATION
System Operation
• For air flow, the instruction selection (1-7) with the fan control dial has priority.
• If the AUTO switch is pressed or if the DEF switch is pressed while in the OFF condition, it changes to the
automatic control by A/C auto amp.
• When increasing the air flow, it changes the duty ratio of the blower motor drive signal to prevent the air flow
from suddenly increasing.
• There are the following types of air flow control: starting air flow control, starting air flow control at low cool-
ant temperature, starting air flow control at high in-vehicle temperature, and air flow control at actuator oper-
ation in addition to instruction control, normal automatic air flow control.
Normal Automatic Air Flow Control
• When the target temperature is set by the temperature control dial of A/C control, the A/C auto amp. per-
forms the calculation and decides the target according to the signal from each sensor.
• The A/C auto amp. changes the duty ratio of blower motor drive signal and controls the air flow continuously
so that the air flow becomes the target air flow.
• The minimum air flow will change according to the sunload when the air discharge outlet is VENT or B/L.
