ated.

COMPRESSOR : ECV (Electrical Control Valve)

INFOID:0000000010503102

• ECV (Electrical Control Valve) is integrated in the compressor.

IPDM E/R receives the ECV control signal from A/C amp. via CAN
communication, and ECV is controlled according to the control sig-
nal transmitted from IPDM E/R.

• ECV is controlled according to the control signal transmitted from

IPDM E/R.
The control signal transmitted by IPDM E/R is controlled according
to the ECV control signal transmitted from A/C amp. via CAN com-
munication.

• ECV varies the air pressure balance in the left and right air spaces

that are divided by the swash plate in order to change the angle of
the swash plate inside the compressor.
By changing the swash plate angle, it changes the piston stroke and controls the refrigerant discharge
amount.

compressor is activated.

Refrigerant Discharge Amount Control

• A/C amp. transmits the ECV control signal via CAN communication. IPDM E/R transmits the control signal to

ECV according to the received ECV control signal.

• ECV is controlled according to change in the duty ratio of the transmitted control signal.
• Except when temperature setting is full cold or outlet is DEF, A/C amp. controls the refrigerant discharge

amount according to the required cooling capacity.

• A/C amp. increases the refrigerant discharge amount when evaporator temperature is higher than the target

temperature upper limit, and reduces the refrigerant discharge amount when evaporator temperature is at or
below the target temperature upper limit.

NOTE:
Target temperature upper limit value of evaporator can be changed using “TARGET EVAPORATOR TEMP
UPPER LIMIT SETTING” in “WORK SUPPORT” mode of CONSULT. Refer to

HAC-191, "Setting of Target

• Step motors are used for the mode door motor air mix door motor, and intake door motor.
• Because the step motors do not have position detection mechanisms, there may be a deviation between the

door position recognized by A/C amp. and the actual door position.
Therefore, A/C amp. performs motor zero position reset for aligning its recognized door position with the
actual door position.

• The reset signal is transmitted from A/C amp. to the air mix door motor, mode door motor, and intake door

motor, which then perform zero position reset.

• After any of the following conditions is met, A/C amp. performs motor zero position reset when the ignition

switch is next turned ON.
