SYSTEM DESCRIPTION

CRUISE CONTROL SYSTEM
The cruise control system makes it possible to drive at a
desired speed without using the accelerator pedal. The
ECM controls the throttle opening angle based on
signals from switches and sensors.
The microcomputer which controls the cruise control
system is built into the ECM, and uses is the throttle
position sensor and motor as the actuator.
Constant speed control gets ready when the cruise
control main switch ON-OFF button is pushed (the
CRUISE MAIN indicator light comes on).
By operating the cruise control main switch, the driver
can control the following functions.
HINT:
• The cruise control main switch is an automatic return
type switch which operates only while it is pushed in
each allow direction and turns off when it is released.
• "SET" and "-", "RES" and "+", "ON" and "OFF"
operations are all controlled by using the same
switch.
(a) 'SET' function
When the cruise control main switch is pushed
down to "-/SET", the ECM stores the set speed and
compares it with the actual vehicle speed. If the
actual driving speed is greater than the set speed,
the ECM sends a signal to the throttle position
sensor and motor to close the throttle valve. If lower,
it opens the throttle valve. The cruise control
operative speed range is between the low and high
speed limits.
(b) '+' function
The cruise set speed increases while the cruise
control main switch lever is pushed up to "+/RES".
The vehicle begins to cruise at the newly set speed
when the cruise control main switch l...
