ECD SYSTEM (1CD±FTV)
DESCRIPTION
1. COMMON RAIL SYSTEM
The common rail system stores high±pressure fuel supplied from the supply pump in the common rail and
injects it using the injector. Fuel injection timing and fuel injection volume are regulated by the ECM; it pro-
vides an electric current to the solenoid valve of the injector with the EDU to regulate them.
By storing high±pressure fuel produced in the supply pump in the common rail, this system can always offer
stable fuel injection pressure regardless of the engine speed and engine load, even if a driving speed is low.
In addition, this system uses the injector that opens and closes its fuel passage with the Two±Way±Valve
(TWV) therefore both the fuel injection time and volume are precisely regulated by the ECM.
The ECM monitors internal fuel pressure of the common rail with the fuel pressure sensor and commands
the supply pump to supply fuel to obtain a target internal pressure (approximately 30 to 180 MPa (306 to
1,835 kgf/cm
2, 4,351 to 26,106 psi)). The ECM opens and closed the pressure discharge valve to improve
controllability for the common rail internal fuel pressure.
This system has two divisional fuel injections. It performs ºpilot±injectionº as subsidiary fuel injection prior
to the main fuel injection to make combustion soft, and this helps to reduce engine vibration and noise.

2. IDENTIFICATION OF NOISE SOURCE
(a) Identify the condition under which the noise occurs, and
check the noise filter on the related part.
Condition in which noise occursNoise Source
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Generator
Noise occurs during the A/C or the heater operation.Blower motor
Rapid acceleration while driving on the unpaved road or after the IG switch is
turned ON makes noise.Fuel pump
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes unusual noise.Horn
Stopping the engine erases small noise that has been heard.Ignition
Noise occurs synchronously with the turn signal flash.Flasher
Noise occurs during the window washer operation.Washer
Noise occurs during the engine running, and it continues after the engine
stops.Engine coolant temperature sensor
Noise occurs during the wiper operation.Wiper
Noise occurs when the brake pedal is depressed.Stop light switch
Others.Static electricity stored on the vehicle
(b) Reference:

Make sure first that there is no noise from outside.
Failing to do so makes the noise source detection
difficult and leads to misunderstanding.

The noise should be removed in descending order
of loudness.

Setting the radio untuned makes noise noticeable,
making the recognition of the phenomenon easier.

NOISE OCCURS
INSPECTION PROCEDURE
1 CHECK OF SPEAKER INSTALLATION
(a) Check the speaker installation condition.
(1) Check that each speaker is securely installed.
Standard: Malfunction disappears.
HINT:
The radio is equipped with the noise prevention system that works against only the excessively large noise,
thereby excessively large noise do not occur in the radio. If large noise occurs, check whether or not the earth
on the antenna installation part and the proper noise±prevention equipment are all installed, and whether
or not the improper wiring is held.
Condition in which noise occursNoise type
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Alternator noise
Noise occurs during the A/C or the heater operation.Blower motor noise
Rapid acceleration during the drive on the unpaved road or after the IG
switch is turned ON makes noise.Fuel pump noise
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes noise.Horn noise
Stopping the engine erases the small noise that has been heard.Ignition noise
Noise occurs in turn with the blink of the turn signal flash.Flasher noise
Noise occurs during the window washer operation.Washer noise
Noise occurs during the engine running, and it continues to occur after the
engine is stopped.Water temperature sensor noise
Noise occurs during the wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity on the vehicle
HINT:

Identify the condition under which the noise occurs, and check the noise filter on the related part.

Make sure first that there is no noise from outside. Failing to do so makes the noise occurrence source
detection impossible and leads to misunderstanding.

The noise should be removed in descending order of loudness.
