id0740a2005100


Purpose

•  The climate control unit performs air conditioning according to the operation by the users and the driving conditions of the vehicle.

Function

•  The climate control unit determines optimum air-conditioning 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 blower motor. (See MANUAL AIR CONDITIONER SYSTEM [MANUAL AIR CONDITIONER].)

Construction

•  A wire-type climate control unit has been adopted.
•  The climate control unit consists of a control panel and a control unit.
•  The switches and dials shown in the figure are positioned on the control panel.
