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.

ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
IntroductionEBS011UJ
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
×: Applicable —: Not applicable
*: When DTC and 1st/2nd trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator (MI) on the instrument panel lights up when the same malfunction is detected in
three consecutive trips (Three trip detection logic).
Three Trip Detection Logic and One Trip Detection LogicEBS011UK
On board diagnosis (OBD) system of this vehicle has “Three Trip Detection Logic” and “One Trip Detection
Logic”. For which logic each self-diagnosis corresponds with, refer to EC-973, "
INDEX FOR DTC" .
“Trip” of “Three Trip Detection Logic” means a driving mode in which the self-diagnosis is performed while
driving.
THREE TRIP DETECTION LOGIC
When a malfunction is detected for the first time, 1st trip DTC is stored in the ECM memory. MI does not illumi-
nate at this stage. <1st trip>
When the same malfunction is detected again during the next driving, 2nd trip DTC is stored in the ECM mem-
ory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this stage. <2nd trip>
When the same malfunction is detected again at the third driving, DTC and Freeze Frame Data are stored in
the ECM memory and 2nd trip DTC is cleared from the ECM memory. MI illuminates at the same time when
DTC is stored. <3rd trip>
In other words, DTC and Freeze Frame Data are stored and MI illuminates when the same malfunction occurs
in 3 consecutive trips.
This is called “Three Trip Detection Logic”.
ONE TRIP DETECTION LOGIC
When a malfunction is detected for the first time, DTC and Freeze Frame Data are stored in the ECM memory
and MI lights up. This is called “One Trip Detection Logic”. Some self-diagnoses will not illuminate MI when
DTC is stored. (Refer to EC-996, "
Emission-related Diagnostic Information" .) 1st/2nd trip DTC is not stored for
one trip detection logic.
