AUTOMATIC SPEED CONTROL DEVICE (ASCD)

AUTOMATIC SPEED CONTROL DEVICE (ASCD)PFP:18930
System DescriptionEBS01FEB
INPUT/OUTPUT SIGNAL CHART
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 185 km/h (115 MPH).
ECM controls fuel injection value 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 MAIN switch. (The CRUISE indicator in combination meter illuminates.)
When vehicle speed reaches a desired speed between approximately 40 km/h (25 MPH) and 185 km/h (115
MPH), press SET switch. (Then SET indicator in combination meter illuminates.)
ACCEL OPERATION
If the RESUME/ACCELERATE 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 or gear position is changed to the neutral position

Vehicle speed increased to 13 km/h higher than the set speed

Vehicle speed decreased to 13 km/h lower than the set speed

ESP 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 lamp.

Malfunction for some self-diagnoses regarding ASCD control: SET lamp 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 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/ACCELERATE 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

Vehicle speed is greater than 40 km/h (25 MPH) and less than 185 km/h (115 MPH)

ASCD INDICATOR

ASCD INDICATORPFP:24814
Component DescriptionEBS01FED
ASCD indicator lamp illuminates to indicate ASCD operation status. The Lamp has two indicators, CRUISE
and SET, and is integrated in combination meter.
CRUISE indicator illuminates when MAIN switch on ASCD steering switch is turned ON to indicated that
ASCD system is ready for operation.
SET indicator illuminates when the following conditions are met.

CRUISE indicator is illuminated.

SET/COAST switch on ASCD steering switch is turned ON while vehicle speed is within the range of
ASCD setting.
SET indicator remains lit during ASCD control.
Refer to EC-1690, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for the ASCD function.

CAN CommunicationECS00CTB
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

DTC VEHICLE SPEED SENSOR MTR

DTC VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionECS004SM
The vehicle speed sensor·MTR is built into the speedometer assem-
bly. The sensor functions as an auxiliary device to the revolution sen-
sor when it is malfunctioning. The TCM will then use a signal sent
from the vehicle speed sensor·MTR.
On Board Diagnosis LogicECS00CUR
Possible CauseECS00CUS
Check the following items.

Harness or connector
(The sensor circuit is open or shorted.)

Vehicle speed sensor
DTC Confirmation ProcedureECS00CUT
CAUTION:

Always drive vehicle at a safe speed.

If conducting this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 5 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
