ENGINE CONTROL

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.

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.
