AIR CONDITIONING SYSTEM(for Manual Air Conditioning System) SYSTEM DESCRIPTION


  1. GENERAL


    1. The air conditioning system has the following features:


      • The air conditioning amplifier controls the operation of parts, such as the A/C compressor, automatically in accordance with the operating conditions of the air conditioning system.

      • The Positive Temperature Coefficient (PTC) heater system contains a PTC heater that heats the air that has passed through the heater core to ensure proper heater performance. The PTC heater is applicable and automatically controllable to 600 W, 450 W and 150 W, because of its self-regulating characteristics.

      • A combustion type power heater is available as optional equipment to provide comfortable heater performance in cold areas.

      • A compact, lightweight, and highly efficient straight flow (full-path flow) aluminum heater core is used.

      • The micro dust and pollen filter control is used to remove pollen in the air around the upper areas of the driver and front passenger seats.

      • The air conditioning amplifier assembly is equipped with a self diagnosis function. If there is a malfunction in the system, it stores DTCs (Diagnostic Trouble Codes) in its memory.

    Tech Tips


    • The size of the circle indicates the proportion of airflow volume.

    • The same system is used for LHD and RHD vehicles.
