AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description
INFOID:0000000010935573
BASIC ASCD SYSTEM
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 170 km/h (105 MPH).
ECM controls fuel injector to regulate engine speed.
Operation status of ASCD is indicated on the information display in the combination meter. If any malfunction
occurs in ASCD system, it automatically deactivates control.
NOTE:
Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.
SET OPERATION
Press ASCD MAIN switch. (CRUISE indicated on the information display)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 170 km/h (105
MPH), press SET/COAST switch. (SET indicated on the information 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 keep 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 at ASCD steering switch are pressed at the same time (Set speed will be cleared)
• Brake pedal is depressed
• Clutch pedal is depressed or gear position is changed to neutral position.
• Vehicle speed decreased under 15% of the set speed from 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 indicator.
• Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE indicator may
blink slowly.
When the engine coolant temperature decreases to the normal operating temperature, CRUISE indicator 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 during 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 keep the new set speed.
RESUME OPERATION
When the RESUME/ACCELERATE switch is pressed after cancel operation other than pressing ASCD MAIN
switch is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition
must meet following conditions.
• Brake pedal is released
• Clutch pedal is released
• Vehicle speed is greater than 40 km/h (25 MPH) and less than 170 km/h (105 MPH)
SPEED LIMITER
SPEED LIMITER : System Description
INFOID:0000000010935574
BASIC SPEED LIMITER SYSTEM
The speed limiter is a system that enables to restrict the vehicle speed within the set speed that is selected by
the driver. Driver can set vehicle speed between 30 km/h and 180 km/h (in the metric system mode) or 20
MPH and 115 MPH (in the yard/pound system mode). ECM controls fuel injector to regulate vehicle speed.
Operation status of speed limiter is indicated on the information display in the combination meter. If any mal-
function occurs in speed limiter system, it automatically deactivates control.
