BASIC SERVICE PROCEDURE

BASIC SERVICE PROCEDUREPFP:00018
Fuel FilterEBS01172
DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump to bleed air.

When air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.

If it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.

Start engine and let it idle for at least 1 minute after performing
air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.

It is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will dam-
age the cock thread, resulting in water or fuel leak.
3. Bleed air of the fuel filter. Refer to EC-994, "
AIR BLEEDING" .
4. Start the engine.
Fuel Pump Learning Value ClearingEBS01173
DESCRIPTION
In order to always keep optimum fuel pressure in fuel rail, the ECM controls fuel pump in high precision with
monitoring the signal of fuel rail pressure sensor.
Accordingly, the ECM always learns characteristic value of fuel pump. Fuel Pump Learning Value Clearing is
an operating to clear the value of the fuel pump learning.
It must be performed after the fuel pump is changed. When the ECM is replaced with brand new one, the Fuel
Pump Learning Value Clearing is not necessary to be performed. If the ECM to be replaced has the possibility
of learning the characteristic value of fuel pump, the Fuel Pump Learning Value Clearing is necessary to be
performed after the ECM has been replaced.
OPERATION PROCEDURE
NOTE:
When removing fuel pump, perform Fuel Pump Learning Value Clearing before starting engine.
