BASIC ASCD SYSTEM
Refer to Owner's Manual for ASCD operating instructions.
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/
h (25 MPH) and 144km/h (90 MPH).
ECM controls throttle angle of electric throttle control actuator to regulate engine speed.
Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any
malfunction occurs in ASCD system, it automatically deactivates control.
Refer to
EC-656, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : Switch Name and Function"
for ASCD
operating instructions.
NOTE:
Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws.

INTEGRATED CONTROL SYSTEM : System Description

CVT models
System Description
TCM transmits a drive mode select signal to ECM via CAN communication, according to a NORMAL mode
signal, SPORT mode signal, or ECO mode signal received from the multi display unit via CAN communication.
ECM controls torque and throttle opening angle characteristics appropriate for each mode, based on a
received drive mode select signal.
NOTE:
• Because of the multi display unit operation, the display may indicate that the mode is switching. However,
the mode may not actually switch due to CAN communication error.
• When a CAN communication error occurs between ECM and TCM, the mode switches to NORMAL mode.
M/T models
System Description
ECM controls torque and throttle opening angle characteristics appropriate for each mode, based on a NOR-
MAL mode signal, SPORT mode signal, or ECO mode signal received from the multi display unit via CAN
communication.
NOTE:
• Because of the multi display unit operation, the display may indicate that the mode is switching. However,
the mode may not actually switch due to CAN communication error.

CAN COMMUNICATION
CAN COMMUNICATION : System Description
INFOID:0000000012198234
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to
LAN-30, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
munication for detail.
Mode
Control
NORMAL mode
Offers a better balance of fuel economy and traveling performance.
SPORT mode
Allows throttle opening angle change and torque control for obtaining reality and acceleration perfor-
mance appropriate to a winding run.
ECO mode
Allows throttle opening angle change and torque control for assisting better fuel efficiency.

SWITCHES AND INDICATORS
SET SPEED RANGE
ASCD system can be set the following vehicle speed.
SWITCH OPERATION
SET OPERATION
Press MAIN switch. (The CRUISE indicator in combination meter illuminates.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 144 km/h (90
MPH), press COAST/SET switch.
ACCELERATE OPERATION
If the ACCEL/RES switch is pressed during the cruise control driving, increase the vehicle speed until the
switch is released or vehicle speed reaches maximum speed controlled by the system.
And then ASCD will keep the new set speed.
CANCEL OPERATION
• When any of following conditions exist, the cruise operation is canceled.
- CANCEL switch is pressed
- ASCD MAIN switch is pressed (Set speed is cleared)
- More than 2 switches at ASCD steering switch are pressed at the same time (Set speed is cleared)
- Brake pedal is depressed
- Clutch pedal is depressed or gear position is changed to neutral position. (M/T models)
- Selector lever is changed to N, P or R position (CVT models)
- Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed
- TCS system is operated
