GENERAL INFORMATION

M2170001001522

For the accelerator system, an electronic throttle
valve control system has been adopted, eliminating
of an accelerator cable.

This system detects the amount of the accelerator
pedal movement by using an accelerator pedal posi-
tion sensor in the accelerator pedal assembly for
electronically controls the throttle valve.

CRUISE CONTROL SYSTEM

GENERAL INFORMATION

M2170001001533

The cruise control system, which provides the con-
stant speed driving without depressing the accelera-
tor pedal at a vehicle speed determined by the driver
(within the range from approx. 40 to 200 km/h).

For this cruise control system, in conjunction with the
electronic throttle valve control system, the
engine-ECU electronically controls the throttle valve.

COMPONENTS AND FUNCTIONS

Component

Function

ABS-ECU <Vehicles without ASC> or
ASC-ECU <Vehicles with ASC>

Outputs the cruise control cancel signal to the engine-ECU.

Accelerator pedal position sensor

Informs the engine-ECU of the accelerator pedal depression.

Cruise control indicator lamp <standard
meter> or cruise control display screen
<high contrast meter>

When the ON/OFF switch is pressed, a lamp will illuminate or a
screen will be displayed to inform the driver that the cruise
control system is active.

switch

Power switch for cruise control system.

RES + switch

Vehicle speed is set with the RES + switch and SET

− switch.

SET

− switch

CANCEL switch

Cancels the constant speed driving.

CVT-ECU

• Controls the CVT based on the CVT control signal from the

engine-ECU.

• The selector lever "N" position signal from the inhibitor switch

is sent to the engine-ECU.

• Outputs the signal from the secondary pulley speed sensor to

the engine-ECU.

Diagnosis connector

If the M.U.T.-III is connected, the diagnosis code and data list
from the engine-ECU can be read.

Engine-ECU

• Based on the input signal from each sensors and switches,

the throttle opening angle indication signal is sent.

• Based on the input signal from each sensors and switches,

the CVT control signal is sent to the CVT-ECU.

• Based on the secondary pulley speed sensor signal from the

CVT-ECU, it calculates the vehicle speed.

• Based on the selector lever "N" position signal from the

CVT-ECU, it cancels constant speed driving.

• To the cruise control indicator lamp, the cruise control system

ON/OFF signal is sent.

• The diagnosis codes of the cruise control system are sent to

the cruise control indicator lamp.

• The data list of the cruise control system is sent to the

diagnosis connector.

Inhibitor switch

The constant speed driving is cancelled by the selector lever
operation, the "N" position is detected.

Stop lamp switch

• The constant speed driving is cancelled by the brake

operation, the brake pedal operation is detected.

• As for the stop lamp switch, two built-in switches, the stop

lamp switch which is also used for the stop lamp illumination
and the brake switch which is used exclusively for the cruise
control, are integrated, and thus the reliability is enhanced.

Throttle valve control servo

The throttle valve opens and closes in response to the throttle
angle control signal from the engine-ECU.

Throttle position sensor

Informs the engine-ECU of the throttle valve opening angle.

CONSTRUCTION AND OPERATION

M2170002000890

The cruise control section in engine-ECU calculates
the cruise control system operation condition based
on the signals sent from switches and sensors.
Based on the calculation, the cruise control section
outputs the target accelerator pedal opening angle
signal to the engine control section, and CVT control
signal to CVT-ECU, and cruise control status
(ON/OFF, etc.) to the combination meter, respec-
tively.

In the engine control section, the target throttle valve
opening angle is calculated based on the target
accelerator pedal opening angle signal from the
cruise control section and the actual accelerator
pedal opening angle signal from the accelerator
pedal position sensor, and the vehicle speed is con-
trolled by operating the throttle valve control servo.
The combination meter will turn on the cruise control
indicator lamp <Standard meter> or the cruise con-
trol display screen <High contrast meter> when the
cruise control system is active. On the high contrast
meter, "SET" symbol will also appear in the screen
during constant speed driving.

SYSTEM FUNCTIONS

SET FUNCTION

1. While driving in the vehicle speed range of

approximately 40 to 200 km/h, press the SET

−

switch.

2. The cruise control system stores the vehicle

speed when the SET

− switch is released, and

then performs a constant speed driving at the
stored vehicle speed.

3. When the SET

− switch is operated while driving

at the vehicle speed of high speed limit
(approximately 200 km/h) or faster, the constant
speed driving is not performed.
