Cruise Control: Description and Operation

AUTOMATIC SPEED CONTROL DEVICE (ASCD) SYSTEM

Input/Output Signal Chart:

DESCRIPTION

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 KPH (25 MPH) and 144 KPH (89 MPH).

ECM controls throttle valve operating angle of electric throttle control actuator to regulate engine speed. Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any malfunction occurs in ASCD system, it automatically deactivates control.

Set Operation
Press ASCD CRUISE switch (Main switch). (Then CRUISE indicator in combination meter illuminates.)

When vehicle speed reaches a desired speed between approximately 40 KPH (25 MPH) and 144 KPH (89 MPH), press SET switch. (Then SET indicator in combination meter illuminates.)

Accel Operation
If the RESUME/ACCEL switch is depressed 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 depressed.
- More than 2 switches at ASCD steering switch are depressed at the same time (Set speed will be cleared.).
- Brake pedal is depressed.
- Clutch pedal is depressed (M/T models).
- A/T selector lever is shifted to P, N or R position (A/T models).
- Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed
- TCS system is operated
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 depressed 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/ACCEL switch is depressed after cancel operation other than depressing 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 (M/T models).
- A/T selector lever is in other than P and N position (A/T models).
- Vehicle speed is greater than 40 KPH (25 MPH) and 144 KPH (89 MPH).
