CLIMATE CONTROL UNIT

id074000004100

Front Climate Control Unit Type A

Purpose

• The front climate control unit controls the air conditioner in conjunction with the operation by the user and the vehicle driving conditions.

Functions

• The front climate control unit determines the air-conditioning conditions based on the input signals from each sensor and the control module and the operation signals from the control panel, and controls each actuator, A/C compressor, and the front blower motor. (See FULL-AUTO AIR CONDITIONER SYSTEM.)

Set temperature display switching function

• When the ambient temperature display in the instrument cluster is switched between Centigrade and Fahrenheit, the set temperature display in the climate control unit is switched between Centigrade and Fahrenheit. (See ENTERTAINMENT SYSTEM.)

Automatic configuration function

• When the ignition is switched ON after the front climate control unit is replaced, the front climate control unit reads the vehicle specification information sent from the instrument cluster as a CAN signal, and stores the vehicle specification information.

• The vehicle specification information recorded by the front climate control unit is not erased even if the ignition is switched off.

• The vehicle specification information recorded by the front climate control unit is erased if the battery power is disconnected.

DUAL control

• To turn on the DUAL control, press the front climate control unit DUAL switch or operate the temperature control dial (passenger’s sde). (DUAL switch indicator turns on)

• When the DUAL control turns on, the driver and passenger-side temperature settings can be performed independently by operating the temperature setting dials (LH)/(RH).

• When the DUAL control turns on, the temperature setting display in the display panel is displayed independently according to each setting temperature for the driver and passenger sides.

Structure/Construction

• A logic-type front climate control unit has been adopted.

• The front climate control unit consists of a control panel, display panel, and a control unit.

• The switches and dials shown in the figure are positioned on the control panel.

• The air conditioning system setting is displayed in the display panel.

Operation

• For the front climate control unit operation, refer to the [FULL-AUTO AIR CONDITIONING SYSTEM]. (See FULL-AUTO AIR CONDITIONER SYSTEM.)

Front Climate Control Unit Type B

Purpose

• The front climate control unit controls the air conditioner in conjunction with the operation by the user and the vehicle driving conditions.

Functions

Set temperature display switching function

Automatic configuration function

• The vehicle specification information recorded by the front climate control unit is not erased even if the ignition is switched off.

• The vehicle specification information recorded by the front climate control unit is erased if the battery power is disconnected.

DUAL control

• When the SYNC mode is on, the passenger temperature setting operates in conjunction with the driver temperature setting. (SYNC switch indicator turns on)

• When the front climate control unit SYNC switch is pressed or the temperature control dial (passenger's side) is operated while the SYNC mode is on, the SYNC mode turns off. (SYNC switch indicator turns off)

• When the SYNC mode turns off, the driver and passenger-side temperature settings can be performed independently by operating the temperature setting dials (LH)/(RH). In addition, the temperature setting display in the display panel is displayed independently according to each setting temperature for the driver and passenger sides.

Structure/Construction

• A logic-type front climate control unit has been adopted.

• The front climate control unit consists of a control panel, display panel, and a control unit.

• The switches and dials shown in the figure are positioned on the control panel.

• The air conditioning system setting is displayed in the display panel.

Rear Climate Control Unit

Purpose

• The rear climate control unit controls the air conditioner in conjunction with the operation by the user and the vehicle driving conditions.

Functions

• The rear climate control unit determines the air-conditioning conditions based on the input signals from each sensor and the control module and the operation signals from the control panel, and controls each actuator and the rear blower motor. (See FULL-AUTO AIR CONDITIONER SYSTEM.)

Front/rear air conditioner interlock function

• When [SYNC] is displayed in the display panel of the rear climate control unit, the airflow temperature setting (rear) is linked to the airflow temperature setting (front).

Structure/Construction

• A logic-type rear climate control unit has been adopted.

• The rear climate control unit consists of a control panel, display panel, and a control unit.

• The switches shown in the figure are positioned on the control panel.

• The rear air conditioning system setting is displayed in the display panel.
