INTEGRATED CONTROL SYSTEM : System Description

INFOID:0000000012197693

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.

• When a CAN communication error occurs between ECM and the multi display unit, the mode switches to

NORMAL mode.

CAN COMMUNICATION
CAN COMMUNICATION : System Description

INFOID:0000000012197694

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"

, about CAN com-

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

Item

Function

CANCEL switch

Cancels the cruise control driving.

ACCEL/RES switch

• Resumes the set speed.
• Increases speed incrementally during cruise control driving.

COAST/SET switch

• Sets desired cruise speed.
• Decreases speed incrementally during cruise control driving.

ASCD MAIN switch

Master switch to activate the ASCD system.

OPERATION

• When the ECM detects any of the following conditions, the ECM cancels the cruise operation and informs

the driver by blinking CRUISE indicator lamp.

- Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE indicator lamp

is blinked slowly.

NOTE:

Engine coolant temperature decreases to the normal operating temperature, CRUISE indicator lamp stop

blinking and the cruise operation is able to work.

- Malfunction for some self-diagnoses regarding ASCD control: CRUISE indicator will blink quickly.

• When ASCD MAIN switch is turned to OFF during the cruise control driving, all of ASCD operations is can-

celed and vehicle speed memory is erased.

COAST OPERATION

When the COAST/SET switch is pressed during the cruise control driving, decrease vehicle set speed until the

switch is released. And then ASCD will keep the new set speed.

RESUME OPERATION

• When the ACCEL/RES switch is pressed after the cancel operation other than pressing ASCD MAIN switch

is performed, vehicle speed is return to last set speed. To resume vehicle set speed, vehicle condition must

meet following conditions.

- Brake pedal is released

- Clutch pedal is released (M/T models)

- Selector lever is in other than P and N positions (CVT models)

- Vehicle speed is greater than 40 km/h (25 MPH) and less than 144 km/h (90 MPH)
