AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description
INFOID:0000000010120569
SYSTEM DIAGRAM
BASIC ASCD SYSTEM
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at a 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).
VCM controls the traction motor to regulate vehicle 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.
For the switch function, Refer to
EVC-69, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : Switch Name
For the ASCD indicator, Refer to
EVC-66, "WARNING/INDICATOR/CHIME LIST : Indicator/Information"
CAUTION:
Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.
CANCEL OPERATION
When any of following conditions exist, cruise operation is cancelled.
• CANCEL switch is pressed
• More than two switches on ASCD steering switch are pressed at the same time (Set speed is cleared)
• Brake pedal is depressed
• Selector lever position is N, P or R position
• TCS system is operated
When VCM detects malfunction for some self-diagnoses regarding ASCD system, VCM cancels the cruise
operation and informs the driver by blinking SET indicator lamp quickly.
If ASCD MAIN switch is turned to OFF while ASCD is activated, all of ASCD operations are cancelled and
vehicle speed memory is erased.

ECO INDICATOR CONTROL : System Description
INFOID:0000000010120570
SYSTEM DIAGRAM
INPUT/OUTPUT SIGNAL CHART
DESCRIPTION
VCM calculates the instantaneous ECO operability based on the driver accelerator operation, brake operation,
vehicle idle time, and air conditioner operation status and displays this in the instant ECO indicator.
Furthermore, VCM samples the instantaneous ECO operability every second and compares it to the map
stored by VCM to calculate the cumulative ECO drivability, and if this value exceeds the set value, then the
ECO tree segment is illuminates.
NOTE:
Once the ECO tree segment is illuminated, it does not turn OFF (dim) during the current trip.
NOTICE:
The idle time is the status when not driving in the READY state.
For details regarding the ECO indicator functions, refer to
MWI-27, "ECO INDICATOR : System Description"
