SFA-II Heater Core (SFA-II: Straight Flow Aluminum-II)

This heater core has been made more compact and higher performance by making the core section finer and improving the shapes of the tank section and flow section. Also, the environment is considered. By using aluminum as the material, the amount of the environmental burden disposal (lead) is reduced.

BUS Connector (Only for Models with Automatic Air Conditioning)

A BUS connector is used in the wire harness connection that connects the servomotor from the air conditioning ECU.

The BUS connector has a built-in communication/drive IC, which communicates with each servomotor connector, actuates the servomotor, and has a position detection function. This enables bus communication for the servomotor wire harness to realize a more lightweight construction and the reduced number of wires.
