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)
Sensor Input signal to ECM ECM function Actuator

WARNING:
Be sure to read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
1. Check fuel level on fuel gauge. If gauge indicates more than the
level as shown in the figure (full or almost full), drain fuel from
fuel tank until gauge indicates level as shown in the figure or
below.
NOTE:
Fuel will be spilled when removing main and sub fuel level sen-
sor units for the top of the fuel is above the main and sub fuel
level sensor units installation surface.

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 15 (3-1/4 Imp gal) of
fuel are drained from fuel tank.

In case fuel pump does not operate, perform the following
procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
draw fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-11, "
FUEL TANK" .
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-49, "
FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-562, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Open fuel filler lid.
4. Open fuel filler cap and release the pressure inside fuel tank.
5. Lift to hold rear seat cushion up. Refer to SE-32, "
REAR SEAT" .
1. Lock ring 2.Main fuel level sensor unit, fuel filter
and fuel pump assembly3.Jet pump, fuel hose and jet pump

6. Remove inspection hole cover for main and sub fuel level sen-
sor units by turning clips clockwise by 90 degrees.

Remove cover by pushing it, then by turning clips clockwise
by 90 degrees and by matching both cover hole and clip
shape.
7. Disconnect harness connector and fuel feed hose.

Disconnect quick connector as follows:
–Hold the sides of connector, push in tabs and pull out fuel feed
hose.
–If quick connector sticks to tube of fuel level sensor unit, push
and pull quick connector several times until it starts to move.
Then disconnect quick connector by pulling.

CAUTION:

Quick connector can be disconnected when the tabs
are completely depressed. Do not twist it more than
necessary.

Do not use any tools to disconnect quick connector.

Keep resin tube away from heat. Be especially careful
when welding near the resin tube.

Prevent acid liquid such as battery electrolyte, etc.
from getting on resin tube.

Do not bend or twist resin tube during installation and
disconnection.

Do not remove the remaining retainer on hard tube (or
the equivalent) except when resin tube or retainer is
replaced.

When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with a new one.

Replace same color retainer as before replacing.

To keep the connecting portion clean and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
8. Using a fuel tank lock ring wrench (commercial service tool),
remove lock ring.
9. Remove main fuel level sensor unit, fuel filter and fuel pump assembly, and sub fuel level sensor unit as
follows.
CAUTION:

Do not bend float arm during removal.

Avoid polluting the inside by residue fuel. Draw out with avoiding inclination by supporting with
a cloth.

Avoid impacts such as falling when handling components.Retainer color: Green
