GENERAL INFORMATIONM2170001000659
For the accelerator system, an electronic throttle
valve control system has been adopted, disposing of
an accelerator cable. This system detects the accel
-
erator pedal travel by using a accelerator pedal posi-
tion sensor (APP sensor) in the accelerator pedal
assembly for electronic control of the throttle valve
angle.

AUTO-CRUISE CONTROL SYSTEM
GENERAL INFORMATIONM2170001000682
By using the auto-cruise control system, the driver
can drive at preferred speeds in a range of approxi
-
mately 40 to 200 km/h (25 to 125 mph) without
depressing the accelerator pedal.
For this auto-cruise control system, in conjunction
with the electronic throttle valve control system, the
engine control module (ECM) electronically controls
the throttle valve.

COMPONENTS AND FUNCTIONS
ComponentFunction
Accelerator pedal position sensor (APP sensor)Informs the ECM of the accelerator pedal
depression.
Auto-cruise control switch"ON/OFF" switchPower switch for auto-cruise control system.
"ACC/RES" switchVehicle speed is set with the "ACC/RES" switch and
"COAST/SET" switch.
"COAST/SET" switch
"CANCEL" switchCancels the cruise speed setting.
Cancel systemClutch switch Because the constant speed driving is cancelled by
the clutch operation, the clutch pedal status is
detected.
Stoplight switch•Because the constant speed driving is canceled
by the brake operation, it detects the brake pedal
status.
•As for the stoplight switch, two built-in switches,
the stoplight switch which is also used for the
stoplight illumination and the brake switch which
is used exclusively for the auto-cruise control, are
integrated, and thus the reliability is enhanced.
Transmission range
switch Because the constant speed driving is cancelled by
the selector lever operation, it detects the "N"
position.
"CRUISE" indicator lightThe light is included in the combination meter and
illuminates when the "ON/OFF" switch is pressed
(auto-cruise control system: ON).
Data link connectorIf the M.U.T.-III scan tool is connected, the input
check code from the ECM can be read.
Engine control module (ECM)•Based on the input signal from each sensor and
switch, it outputs the throttle opening instruction
signal to the TAC motor.
•Based on the input signal from each sensor and
switch, it outputs the transaxle control signal to
the TCM .
•Based on the vehicle speed signal from the
vehicle speed sensor, it calculates the vehicle
speed .
•Based on the secondary pulley speed sensor
signal from the TCM, it calculates the vehicle
speed .
•Based on the selector lever "N" position signal of
the transmission range switch from the ECM, it
cancels constant speed driving. .
•Outputs the ON/OFF signals of "CRUISE"
indicator light and auto-cruise control system.
•The diagnostic trouble code signal is sent to the
"CRUISE" indicator light.
•The input check code is sent to the data link
connector.
Throttle actuator control motor (TAC motor)The throttle valve opens and closes in response to
the throttle angle signal from the ECM.

CONSTRUCTION AND OPERATIONM2170002000232
SYSTEM OUTLINE
The ECM calculates the auto-cruise control system
operation status when the ECM receives input sig
-
nals from the auto-cruise control switch, vehicle
speed and cancel system [stoplight switch and clutch
switch or transmission range switch ]. The engine control section sends the target acceler
-
ator pedal opening angle value for auto-cruise con-
trol system, the TCM issues a command to transaxle
control , and the gauge issues an ON/OFF
command for the "CRUISE" indicator light.
In the engine control section, the target throttle valve
opening angle value is calculated from the target
accelerator pedal opening angle value for
auto-cruise control system and the actual accelerator
angle value.The vehicle speed is then controlled by
applying the TAC motor.

Transaxle control module (TCM) •Based on the transaxle control signal from the
ECM, it controls the transaxle.
•Outputs the signal from the secondary pulley
speed sensor to the ECM.
•Transmits the selector lever "N" position signal
from the transmission range switch to the ECM.
Vehicle speed sensor Transmits the vehicle speed signal proportional to
the vehicle speed to the ECM.
