DTC P1720 VSSPFP:31036
DescriptionEBS018OH
NOTE:
If DTC P1720 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
EC-633, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from ESP/TCS/ABS
control unit (models with ESP) or “ABS actuator and electric unit (control unit)”(models without ESP), and the
other is from TCM (Transmission control module). ECM uses these two signals for engine control.
CONSULT-II Reference Value in Data Monitor ModeEBS018OI
Specification data are reference values.
On Board Diagnosis LogicEBS018OJ
The MI will not light up for this diagnosis.
DTC Confirmation ProcedureEBS018OK
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine.
4. Drive vehicle at a speed of 20 km/h (12 MPH) or more for at least 5 seconds without brake pedal depress-
ing.
5. If 1st trip DTC is detected, go to EC-808, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle at a speed of 20 km/h (12 MPH) or more for at least 5 seconds without brake pedal depress-
ing.
3. Stop the vehicle.
4. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.

AUTOMATIC SPEED CONTROL DEVICE (ASCD)PFP:18930
System DescriptionEBS01FBZ
INPUT/OUTPUT SIGNAL CHART
*: This signal is sent to the ECM through CAN communication line.
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 144 km/h (89 MPH).
ECM controls throttle 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.
NOTE:
Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws.
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 144 km/h (89
MPH), press SET/COAST switch. (Then SET indicator in combination meter illuminates.)
ACCEL 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 the neutral position

Vehicle speed decreased to 13 km/h (8 MPH) lower than the set speed

ESP/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 lamp.

Engine coolant temperature is slightly higher than the normal operating temperature, CRUISE lamp may
blink slowly.
When the engine coolant temperature decreases to the normal operating temperature, CRUISE lamp 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 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.
