On Board Diagnosis LogicEBS00KJ3
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to LC-11. Also, replace the
engine oil. Refer to LC-8.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-21.
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS00KJ4
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-600,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-600,
"Diagnostic Procedure" .
3. Turn ignition switch “ON”.

IVT CONTROL SOLENOID VALVEPFP:23796
DescriptionEBS00KLL
SYSTEM DESCRIPTION
*: This signal is sent to the ECM through CAN communication line.
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake
valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant
temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to
increase engine torque in low/mid speed range and output in high-speed range.
COMPONENT DESCRIPTION
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

InstallationNJEC0618S01021. Referring to the figure and the marking which were made for
installation, connect the injection tubes to all the cylinders.
2. Connect temporarily the tubes to the cylinder head side only
by screwing 2 to 3 turns. Make sure that all tubes can be con-
nected to the pump side also.
3. Then, tighten the flare nuts of the cylinder head side and pump
side, starting from the opposite side from you.

4. Attach the injection tube clamp in the direction shown in the
figure.
5. Insert tightening bolts of the clamp (4-tube type) from the rear
to the front of the engine.

Injection Nozzle Oil SealNJEC0618S02RemovalNJEC0618S0201Using a tool such as a flat-bladed screwdriver, pry the flange of the
seal, then remove it.
Installation
NJEC0618S02021. After the high-pressure injection nozzle assembly is installed,
push the seal from the cylinder head side until it contacts the
flange.
2. Make sure that the garter spring of the seal on the high-pres-
sure injection nozzle assembly side is not falling.
Replace the oil seal with new one when the high-pressure
injection nozzle assembly is removed. (It is not necessary
to replace the oil seal when only injection tubes are
removed.)
