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
fixed 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 untill acceleration
switch released.
Vehicle speed at the acceleration switch released
plus 1.0 km/h 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
approx. 1.0 km/h is stored in the control unit as the
set speed.
Tap down Function
During cruise control driving, the set speed can be
lowered approx. 1.0 km/h 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 still stored.
Down Cancel Function
The cruise control is canceled when the vehicle
speed becomes the set speed minus 20 km/h 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 km/h 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 km/h.
