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

M2170001001555

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. <Petrol engine>

• For this cruise control system, due to the adop-

tion of the common rail fuel control system, the 
engine-ECU electrically controls the fuel injection 
system. <Diesel engine>

• In the situation that a vehicle speed is gradually 

increased without driver’s intention on downhill 

etc, speed limiter

*

 is a driver assist function to 

prevent from exceeding the speed set by driver.

NOTE: 

*

: Adjustable speed limiter

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 cruise control 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.

Speed limiter display screen

When the speed limiter ON/OFF switch is pressed, a screen will 
be displayed to inform the driver.

Cruise control 
switches

Cruise control ON/OFF 
switch

Power switch for cruise control system.

Speed limiter ON/OFF 
switch

Turn ON/OFF the speed limiter.

RES + switch

• Vehicle speed is set with the RES + switch and SET − switch.

• Set vehicle speed of speed limiter is set with the RES + 

switch and SET 

− switch.

SET 

− switch

CANCEL switch

• Cancels the constant speed driving.

• Cancel speed limiter in the activated mode.

CVT-ECU <Petrol engine>

• 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.

A/T-ECU <Diesel engine>

• Controls the automatic transmission shifting based on the 

shift 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.

CONSTRUCTION AND OPERATION

M2170002000919

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 <Petrol engine>, shift control sig-
nal to A/T-ECU <Diesel engine> or clutch switch 
<M/T> and cruise control status (ON/OFF, etc.) to the 
combination meter, respectively.

• 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 controlled by operating the throttle valve 
control servo. <Petrol engine>

• In the engine control section, the amount of fuel 

consumption is calculated based on the target 
engine torque signal from the cruise control sec-
tion and the actual accelerator pedal opening 
angle signal, and the vehicle speed is controlled 
by controlling the fuel injection system. <Diesel 
engine>

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. <Petrol 
engine>

• Based on the secondary pulley speed sensor signal from the 

CVT-ECU, it calculates the vehicle speed. <Petrol engine>

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

CVT-ECU, it cancels constant speed driving. <Petrol engine>

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

the CVT control signal is sent to the A/T-ECU. <Diesel 
engine>

• Based on the secondary pulley speed sensor signal from the 

A/T-ECU, it calculates the vehicle speed. <Diesel engine>

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

A/T-ECU, it cancels constant speed driving. <Diesel engine>

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

ON/OFF signal is sent.

• The diagnosis codes and data list of the cruise control system 

is sent to the diagnosis connector.

Inhibitor switch <CVT, A/T>

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

Clutch switch <M/T>

Because the constant speed driving is cancelled by the clutch 
operation, the clutch pedal status 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 <Petrol 
engine>

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

Throttle position sensor <Petrol engine>

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

Fuel injection system <Diesel engine>

Amount of fuel consumption control signal from engine-ECU.
