2) Function of N Switch
(1) Aids a smooth start of the vehicle by raising the RPM during the gear
shifting when the engine is cold.
When the vehicle is trying to start from the stopped state (vehicle speed below 3 km/h), the N switch
determines the shifting timing by using the clutch switch and the N switch. It raises the engine RPM (100
~ 200 rpm). Operation conditions are as follows.
The vehicle speed is at the stopped state (Vehicle speed below 3km/h detection).
While depressing the clutch (Clutch switch detection).
The gear lever is at a position other than neutral (N switch detection).
Start the vehicle while depressing the clutch pedal (Clutch switch detection).
The RPM increases in accordance with the temperature of the engine coolant
(Engine coolant temperature sensor detection). -

When the gear has been smoothly shifted and the vehicle speed exceeds 3km/h, it returns to the
previous operation interval of the engine RPM. -
In case of Actyon, the N switch signal is transmitted to the instrument panel, and then the instrument
panel transmits it to the engine ECU through the CAN communication.

5. A/C INPUT/OUTPUT DIAGRAM
Below diagram shows the input/output mapping between the components of FATC A/C and A/C
controller briefly.
▶ A/C compressor control by engine ECU
In case of current vehicle models, the system turns ON or OFF the compressor switch according to the
refrigerant pressure, ambient temperature and condenser temperature to protect the A/C circuits.
However, for the vehicles equipped with DI engine, the engine ECU turns off the A/C compressor unde
