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 "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : Switch Name and Function" Operation.

CAUTION:
Always drive vehicle in a safe manner according to traffic conditions and obey all traffic laws.

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.
