DescriptionEBS011PD
SYSTEM DESCRIPTION
Fuel supply entrance of fuel tank is at the left side of fuel tank. The duel at the right side of the fuel tank is sent
to the left side of the fuel tank by fuel transport pump.
When the ECM receives engine revolution signal from the crankshaft position sensor, it knows that the engine
is rotating, and causes the pump operate. If the remainder of the fuel at the right side of the fuel tank
decreases, fuel level switch sends a signal to the ECM. When the ECM receives a signal from the fuel level
switch, the ECM stops the operation of the pump.
The ECM does not directly drive the fuel transport pump. It controls the ON/OFF fuel transport pump relay,
which in turn controls the fuel transport pump.
COMPONENT DESCRIPTION
Fuel Transport Pump
Fuel transport pump sends the fuel from right side of fuel tank to left
side.
Fuel Level Switch
Fuel level switch is assembled in sub fuel level sensor unit. When the remainder of the fuel at the right side of
the fuel tank is less than specified value, the switch is turned OFF.
Sensor Input Signal to ECM ECM function Actuator
Crankshaft position sensor Engine speed
Fuel transport pump control Fuel transport pump relay
Fuel level switch Fuel level
Condition Fuel transport pump operation
Engine is running.Operates
Engine is stopped.Stops
The remainder of the fuel in the fuel tank is less than specified value. Stops

Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureEBS011PG
1. CHECK OVERALL FUNCTION
1. Turn ignition switch OFF.
2. Confirm that the engine is cooled down and there are no fire hazards near the vehicle.
3. Disconnect sub fuel level sensor unit harness connector.
4. Remove sub fuel level sensor unit.
5. Reconnect sub fuel level sensor unit harness connector.
6. Soak fuel level switch in fuel and check operating sound of fuel
transport pump.

AUTOMATIC SPEED CONTROL DEVICE (ASCD)PFP:18930
System DescriptionEBS01F8C
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
