AUTOMATIC AIR CONDITIONING SYSTEM : Temperature Control

INFOID:0000000006546671

• When ignition switch is in the ON position, A/C auto amp. always

automatically controls temperature regardless of air conditioner
operational state.

• A/C auto amp. calculates the target air mix door opening angle

depending on set temperature, in-vehicle temperature, ambient
temperature, and sunload.

• Air mix door is controlled depending on the comparison of current

air mix door opening angle and target air mix door opening angle.

• Regardless of in-vehicle temperature, ambient temperature, and

sunload, air mix door is fixed at the fully cold position when set
temperature is 16

C, and at the fully hot position when set temper-

ature is 30

AUTOMATIC AIR CONDITIONING SYSTEM : Air Outlet Control

INFOID:0000000006546672

• While air outlet is in automatic control, A/C auto amp. selects the

mode door position depending on a target air mix door angle and
outlet air temperature calculated from sunload.

• If ambient temperature is excessively low, D/F is selected to pre-

vent windshield fogging when air outlet is set to FOOT.

AUTOMATIC AIR CONDITIONING SYSTEM : Air Flow Control

INFOID:0000000006546673

DESCRIPTION

• A/C auto amp. changes duty ratio of blower motor drive signal and controls air flow continuously. When air

flow is increased, duty ratio of blower motor drive signal gradually increases to prevent a sudden increase in
air flow.

• In addition to manual control and automatic control, air flow control is compose of starting fan speed control,

low coolant temperature starting control, high in-vehicle temperature starting control, and blower speed con-
trol at door motor operation.

AUTOMATIC AIR FLOW CONTROL

• A/C auto amp. decides target air flow depending on target air mix door opening angle.
• A/C auto amp. changes duty ratio of blower motor drive signal and controls air flow continuously so that air

flow matches to target air flow.

• When air outlet is VENT or B/L, the minimum air flow is changed

depending on sunload.

STARTING FAN SPEED CONTROL

When blower motor is activated, A/C auto amp. gradually increases duty ratio of blower fan drive signal to pre-
vent a sudden increase in discharge air flow. (T

1 –

= approximately 10 seconds)

[TYPE 2]

SYSTEM

Do not perform the starting air flow control when the discharge outlet
is set to DEF.

LOW COOLANT TEMPERATURE STARTING CONTROL

If the engine coolant temperature is 56

C (133

F) or less, to prevent

a cold discharged air flow, A/C auto amp. suspends blower motor
activation for the maximum 100 seconds depending on target air mix
door opening angle. After this, blower fan drive signal is increased
gradually, and blower motor is activated.

FAN SPEED CONTROL AT DOOR MOTOR OPERATION

When mode door motor is activated while air flow is more than the specified value, A/C auto amp. reduces
temporarily fan speed so that mode door moves smoothly.

HIGH IN- TEMPERATURE STARTING CONTROL

When evaporator temperature is high [intake air temperature sensor value is 35

C (95

F) or more], to prevent

a hot discharged air flow, A/C auto amp. suspends blower motor activation for approximately 3 seconds so
that evaporator is cooled by refrigerant.

AUTOMATIC AIR CONDITIONING SYSTEM : Air Inlet Control

INFOID:0000000006546674

• While air inlet is in automatic control, A/C auto amp. selects air

inlet (fresh air intake, 20% fresh air intake, or recirculation)
depending on set temperature, in-vehicle temperature, and ambi-
ent temperature.

• Air inlet is fixed to 80% FRE, only when the conditions are satisfied

as follows:

- Air inlet is FOOT
- Ambient temperature is 8

C (46

F) or less

- Blower motor (applied voltage) is 10 V or more

AUTOMATIC AIR CONDITIONING SYSTEM : Compressor Control

INFOID:0000000006546675

DESCRIPTION

• When the compressor activation condition is satisfied while blower motor is activated, A/C auto amp. trans-

mits A/C ON signal and blower fan ON signal to BCM.

• BCM transmits the A/C ON signal and blower fan ON signal to ECM via CAN communication line.
- With Intelligent Key system: Refer to

BCS-13, "SIGNAL BUFFER SYSTEM : System Description"

- Without Intelligent Key system: Refer to

BCS-103, "SIGNAL BUFFER SYSTEM : System Description"

• ECM judges the conditions of each sensor (Refrigerant pressure sensor signal, accelerator position signal,

etc.), and transmits the A/C compressor request signal to IPDM E/R via CAN communication line.

• By receiving the A/C compressor request signal from ECM, IPDM E/R turns the A/C relay to ON, and acti-

vates the compressor.

AUTOMATIC AIR CONDITIONING SYSTEM : ECO Mode Control

INFOID:0000000006659840

DESCRIPTION

• A/C auto amp. receives operation status of each switch (A/C operation signal), D-MODE setting status (ECO

mode signal), and “CLIMATE ECO” setting status (A/C ECO setting signal) from multi display unit via CAN
communication.

• A/C auto amp. operates air conditioning system in ECO mode, when D-MODE on multi display unit is set to

ECO mode while air conditioning system is in automatic control.
NOTE:
• For setting procedure of D-MODE, refer to

AV-99, "NISSAN DYNAMIC CONTROL SYSTEM : System

Description"

• Activation or deactivation of ECO mode can be changed using multi display unit setting function (“CLI-

MATE ECO”). For setting procedure, refer to

AV-99, "NISSAN DYNAMIC CONTROL SYSTEM : System

Description"

CONTROL OUTLINE

During ECO mode operation, A/C auto amp. changes air flow and control characteristics of air inlet, within a
range that may not spoil the comfort level, lowers operation ratio of compressor, and reduces the electrical
load. This reduces engine load and improved fuel economy. Refer to the following items for details of each
control.

Air Flow Control

• A/C auto amp. increases voltage to power transistor gate compared to ordinary operation and reduces volt-

age to blower motor. This reduces air flow.

• Since air flow is reduced, the amount of air that passes evaporator is reduced. Increase of evaporator tem-

perature can be moderated. Evaporator temperature is easily shifted to temperature control range for low
temperature protection control. Operation ratio of evaporator is reduced.

• Since air flow is reduced, the electrical load is reduced. Alternator power output can be moderated.

Air Inlet Control

• In the following conditions, A/C auto amp. controls air inlet and increases recirculation air mixing ratio com-

pared to ordinary operation.

- Ambient temperature: 25

C (77

F) or more

- Temperature setting: Any temperature other than full cold (16

C) or full hot (30

- Air outlet: In automatic control
- Air flow: In automatic control
- Air inlet: In automatic control or in fresh air intake mode by manual control
- A/C switch: ON
• By increasing recirculation air mixing ratio, cooled air in passenger room is circulated in larger amount than

during ordinary operation. Air temperature blowing to evaporator is maintained at a low level. Evaporator
temperature increase can be moderated. Evaporator temperature is easily shifted to temperature control
range for low temperature protection control. Operation ratio of evaporator is reduced.

PTC HEATER CONTROL SYSTEM

PTC HEATER CONTROL SYSTEM : System Diagram

INFOID:0000000006659834

PTC HEATER CONTROL SYSTEM : System Description

INFOID:0000000006659835

• A/C auto amp. performs PTC relay ON/OFF control based on engine speed, engine coolant temperature,

electrical power cut freeze signal (permission signal, retention signal, stop signal), fan speed, ambient tem-
perature, battery voltage, and electrical load signal (high beam request signal, low beam request signal, rear
window defogger ON signal, and others).

• When PTC relay turns ON, power supply is supplied to PTC heater. Heating element is heated and air flow

temperature is increased. Heating is available for a period of time until engine coolant temperature is
increased when engine starts cold in cold climate.

• Idle up request signal is transmitted from A/C auto amp. to ECM while PTC heater operates. Idle speed is

increased, warming-up is facilitated, and battery electric power is obtained.

• Electric power supplied to PTC heating element is subject to PTC relay control conditions.

NOTE:
PTC heater operation depends on ambient temperature and battery voltage. PTC heater is ON when ambient
temperature is 8

C or less. PTC heater is OFF when ambient temperature is 12

C or more. PTC heater is ON

when battery voltage is 11.5 V or more. PTC heater is OFF when battery voltage is 11 V or less.
