CRUISE CONTROL – CRUISE CONTROL SYSTEMCC–5

SYSTEM DESCRIPTION
1. CRUISE CONTROL SYSTEM
This system is controlled by the ECM, and is activated by
the throttle position sensor and motor. The ECM controls
the following functions: ON-OFF, SET / COAST,
RESUME / ACCEL, CANCEL, vehicle speed operation,
motor output control, and overdrive control.
• The ECM compares the driving vehicle speed from
the combination meter with the stored vehicle speed
set through the cruise control switch. The ECM
controls the throttle valve motor of the throttle body to
open the valve when the driving speed is less than the
stored speed.
• The ECM receives signals such as ON-OFF, SET /
COAST, RESUME / ACCEL, and CANCEL from the
cruise control switch.
• The ECM illuminates the combination meter CRUISE
main indicator light when it receives the cruise control
switch ON signal.
• The ECM cancels the cruise control system when the
brake pedal is depressed and the ECM receives the
stop light switch signal.
• The ECM cancels the cruise control system when the
shift lever is moved from D or 3 to a position other
than D or 3, and the ECM receives the PNP switch
signal.
2. LIMIT CONTROL
(a) Low speed limit
The lowest possible limit of the speed setting range
is set at approximately 40 km/h (25 mph). The
cruise control system cannot be set when the
driving vehicle speed is below the low speed limit.
Cruise control operation will be automatically
canceled when the vehicle speed decreases below
the low speed limit 40 km/h (25 mph) while the
cruise control is in operation.
(b) High speed limit
The highest possible limit of the speed setting range
is set at approximately 200 km/h (125 mph). The
cruise control system cannot be set when the
driving vehicle speed is over the high speed limit.
Also, +/RES cannot be used to increase speed
beyond the high speed limit.

3. OPERATION OF CRUISE CONTROL
The cruise control switch operates 7 functions: SET,
COAST, TAP-DOWN, RESUME, ACCELERATION
(ACCEL), TAP-UP, and CANCEL. The SET, TAP-DOWN
and COAST functions, and the RESUME, TAP-UP and
ACCEL functions are operated with the same switch.
The cruise control switch is an automatic return type
switch which turns on only when pressed in each arrow
direction and turns off when released.
(a) SET CONTROL
Vehicle speed is stored and constant speed control
is maintained when pushing the switch to -/SET
while driving with the cruise control switch ON (the
CRUISE main indicator light is illuminated), and the
vehicle speed is within the set speed range
(between the low and high speed limits).
(b) COAST CONTROL
The ECM changes the cruise control demanding
throttle opening angle to 0
and decelerates the
vehicle when -/SET on the cruise control switch is
pressed and held while the cruise control system is
operating. When the cruise control switch is
released from -/SET, the vehicle speed is stored and
constant speed control is maintained.
HINT:
• The throttle valve is not fully closed due to idle
speed control, etc.
•w/ VSC:
The brake is also used to decelerate the vehicle.
(c) TAP-DOWN CONTROL
When tapping down the cruise control switch to -/
SET (for approximately 0.5 seconds) while the
cruise control system is in operation, the stored
vehicle speed decreases each time by
approximately 1.6 km/h (1.0 mph). When the cruise
control switch is released from -/SET and the
difference between the driving and stored vehicle
speed is less than 5 km/h (3 mph), the vehicle
speed is stored and constant speed control is
maintained.
(d) ACCEL CONTROL
The throttle valve motor of the throttle position
sensor and motor is instructed by the ECM to open
the throttle valve when +/RES on the cruise control
switch is pressed and held while the cruise control
system is operating. When the cruise control switch
is released from +/RES, the vehicle speed is stored
and constant speed is maintained.

The standard normal voltage between each pair of ECM
terminals is shown in the table below. The appropriate
conditions for checking each pair of terminals are also
indicated. The result of checks should be compared with the
standard normal voltage for that pair of terminals, displayed in
the Specified Condition column. The illustration above can be
used as a reference to identify the ECM terminal locations.
