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.

3. ABS CONTROL LOGIC
The principal ABS control logic is the determination of the reference speed by choosing one
wheel meeting a certain condition, while sensing the speed information from 4 wheel speed
sensors when the vehicle is being driven.
For example, when the comparison of the reference speed with front right wheel speed shows a
slip, the control signal is determined according to whether it's deceleration or acceleration. If the
control conditions are met, the brake for the front right wheel will be got under control.
