BASIC SERVICE PROCEDURE
BASIC SERVICE PROCEDURE
PFP:00018
Fuel Filter
EBS014SL
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
.
4.
Start the engine.
Fuel Pump Learning Value Clearing
EBS014SM
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:
Remove fuel pump without starting engine after performing Fuel Pump Learning Value Clearing.

1.
Turn ignition switch ON.
2.
Select “PUMP LEARNT CLEAR” in “ACTIVE TEST” mode with
CONSULT-II.

DTC and MI Detection Logic
EBS014SN
When a malfunction is detected, the malfunction (DTC) and freeze frame data are stored in the ECM memory.
The MI will light up each time the ECM detects malfunction. For diagnostic items causing the MI to light up,
refer to
.
Diagnostic Trouble Code (DTC)
EBS014SO
HOW TO READ DTC
The DTC can be read by CONSULT-II only.
With CONSULT-II
CONSULT-II displays the DTC in “SELF-DIAG RESULTS” mode. Example: P0117, P0335, P1260, etc. These
DTCs are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)
HOW TO ERASE DTC
How to Erase DTC ( With CONSULT-II)
1.
If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 5
seconds and then turn it ON (engine stopped) again.
2.
Touch “ENGINE”.
3.
Touch “SELF-DIAG RESULTS”.
4.
Touch “ERASE”. (The DTC in the ECM will be erased.)
The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.
Freeze Frame Data
EBS014SP
The ECM records the driving conditions such as calculated load value, engine coolant temperature, engine
speed, vehicle speed and intake manifold pressure at the moment a malfunction is detected.
The data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-II. For
details, see
.
Only one set of freeze frame data can be stored in the ECM. If freeze frame data is stored in the ECM memory
and another freeze frame data occurs later, the first (original) freeze frame data remains unchanged in the
ECM memory.
Freeze frame data (along with the DTCs) are cleared when the ECM memory is erased. Procedures for clear-
ing the ECM memory are described in
.

NATS (Nissan Anti-theft System)
EBS014SQ
●
If the security indicator lights up with the ignition switch in
the ON position or “NATS MALFUNCTION” is displayed on
“SELF-DIAG RESULTS” screen, perform self-diagnostic
results mode with CONSULT-II using NATS program card.
Refer to EL-352, NATS “(NISSAN ANTI-THEFT SYSTEM)”.
●
Confirm no self-diagnostic results of NATS is displayed
before touching “ERASE” in “SELF-DAIG RESULTS” mode
with CONSULT-II.
●
When replacing ECM, initialization of NATS system and reg-
istration of all NATS ignition key IDs must be carried out
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedure of NATS initialization and NATS ignition key ID registration, refer to CON-
SULT-II operation manual, NATS.
Malfunction Indicator (MI)
EBS014SR
DESCRIPTION
The MI is located on the instrument panel.
1.
The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
●
If the MI does not light up, refer to EL-115, “WARNING
LAMPS” or see
EC-1528, "MI & DATA LINK CONNECTORS"
.
2.
When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
On Board Diagnostic System Function
The on board diagnostic system has the following two functions.
Diagnostic Test Mode I - Bulb Check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to EL-
“WARNING LAMPS” or see
EC-1528, "MI & DATA LINK CONNECTORS"
.
