Wiring System

General Description
The circuit consists of cruise control unit, cruise main switch, combination switch clutch switch (M/T), mode switch (A/T), brake switch, actuator and indicator lights. Cruise control system keeps the vehicle running at a fix speed until a signal canceling this fixed speed is received. When the cruise main switch is turned on with the vehicle in the running mode, the battery voltage is applied to the control unit.
When a signal from the combination switch is input to the control unit while vehicle is in this state, the actuator is activated to operate the system. Also, while the system is operating, the cruise indicator light in the meter panel lights up.

Set Function
When the cruise main switch turned on and the set switch is depressed with the vehicle speed within the set limit and cancel operation is refused the vehicle speed when the set switch is released is stored in the control unit as the set speed. But in case of the vehicle speed is over maximum limit speed of cruise control, maximum limit speed in the control unit is stored as the set speed.

Resume Function
Unless the vehicle speed falls below the minimum speed limit after canceling the set speed by the cancel switch, pushing the resume switch causes the vehicle to resume the speed before cancellation.

Acceleration Function
During cruise control driving, pushing the acceleration switch (on time is more than 0.6 sec.) causes an increase in cruise speed and vehicle accelerates at a controlled rate until acceleration switch released. Vehicle speed at the acceleration switch released plus 1.0 kph is stored in the control unit as the set speed.

Tap up Function
During cruise control driving, pushing the coast switch (on time is more than 0.6 sec.) causes a decrease in cruise speed and the vehicle decelerate at a controlled rate until coast switch released. Vehicle speed at the coast switch released ,minus 1.0 kph is stored in the control unit as the set speed.

Tap down Function
During cruise control driving, the set speed can be lowered 1.6 kph each time by operating the coast switch quickly within 0.6 sec.

Cancel Function
During cruise control driving, the cruise control is released if the control unit receives a signal from the cancel switch, mode switch, clutch switch or brake switch. But the set speed is not erased.

Down Cancel Function
The cruise control is canceled when the vehicle speed becomes the set speed minus 20 kph during the cruise control working and the set speed is erased.

Over Drive (OD) Cancel Function
OD cancel function is required when the vehicle speed becomes the set speed minus 3 kph during the cruise control working. OD cancel function is enabled when the acceleration function and/or resume function are working except the vehicle speed is in more than 120 kph.
