INPUT/OUTPUT SIGNAL CHART
*: This signal is sent to the ECM via the CAN communication line
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 144 km/h (89 MPH).
ECM controls throttle angle of electric throttle control actuator to regulate engine speed.
The ASCD operation status is indicated by two indicators (CRUISE and SET on the information display) on the
combination meter. If any malfunction occurs in the ASCD system, SET indicator blinks and ASCD control is
deactivated.
NOTE:
Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.
SET OPERATION
Press MAIN switch. (CRUISE is indicator on the information display.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 144 km/h (89
MPH), press SET/COAST switch. (Then SET is indicated on the information display, and the set speed is also
display.)
ACCELERATE OPERATION
If the RESUME/ACCELERATE switch is pressed during 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 maintain the new set speed.
CANCEL OPERATION
When any of following conditions exist, cruise operation will be canceled.
• CANCEL switch is pressed

• More than 2 switches on ASCD steering switch are pressed at the same time (Set speed will be cleared)
• Brake pedal is depressed
• Selector lever position is changed to N, P or R
• Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed
• TCS system is operated
When the ECM detects any of the following conditions, the ECM will cancel the cruise operation and inform
the driver by blinking indicators.
• Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE lamp may
blink slowly.
When the engine coolant temperature decreases to the normal operating temperature, CRUISE lamp will
stop blinking and the cruise operation will be able to work by pressing SET/COAST switch or RESUME/
ACCELERATE switch.
• Malfunction for some self-diagnoses regarding ASCD control: SET indicator will blink quickly.
If MAIN switch is turned to OFF while ASCD is activated, all of ASCD operations will be canceled and vehicle
speed memory will be erased.
COAST OPERATION
When the SET/COAST switch is pressed during cruise control driving, decrease vehicle set speed until the
switch is released. And then ASCD will maintain the new set speed.
RESUME OPERATION
When the RESUME/ACCELERATE switch is pressed after canceling operation other than pressing the MAIN
switch, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must meet
following conditions.
• Brake pedal is released
• A/T selector lever is in a position other than P and N
• Vehicle speed is greater than 40 km/h (25 MPH) and less than 144 km/h (89 MPH)
