Engine speed

If the engine speed is above 2,800 rpm with no load (for example, in neutral and engine speed over 2,800
rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed.
Fuel cut will operate until the engine speed reaches 1,500 rpm, then fuel cut is cancelled.
NOTE:
This function is different from deceleration control listed under “Fuel Injection Control System”,

Fuel Filter

DESCRIPTION

NLEC0623

A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.

SEF375Y

AIR BLEEDING

NLEC0624

After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.

To start the engine, rotate the starter for a maximum of 30
seconds. To start the engine more quickly, crank the engine
while pumping the priming pump (requires two workers).

If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.

Rotate the starter again until the engine starts running.

After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.

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), disconnect the fuel supply hose between the fuel
filter and the injection pump. 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 one minute after
performing air bleeding.

WATER DRAINING

NLEC0625

If the MI lights up (not flashes) during the engine operation,
drain the water as follows. (If fuel filter switch is equipped.)

Remove the fuel filter, filter bracket, protector assembly from
the dash panel as follows.

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.

Disconnect the water level warning sensor harness connector.

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.

Using a tool such as a pliers, loosen the water draining cock
at the bottom of the water level warning sensor located under
the fuel filter.

Water amount when the MI lights up:

65 - 100 m

(2.2 - 3.5 Imp fl oz)

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.

DTC and MI Detection Logic

NLEC0626

When a malfunction is detected, the malfunction (DTC) is 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 “TROUBLE DIAGNOSIS — INDEX”, EC-1064.

Diagnostic Trouble Code (DTC)

NLEC0627

HOW TO READ DTC

NLEC0627S01

The DTC can be read by the following methods.

Without CONSULT-II

ECM displays the DTC by a set of four digit numbers with MI illumination in the diagnostic test mode II (Self-
diagnostic results). Example: 0103, 0807, 1002, etc.

With CONSULT-II

CONSULT-II displays the DTC in “SELF-DIAG RESULTS” mode. Examples: P0115, P0571, P1202, etc.
These DTCs are prescribed by ISO15031-6.
(CONSULT-II also displays the malfunctioning component or system.)

Output of the trouble code means that the indicated circuit has a malfunction. However, in the Mode
II it does not indicate whether the malfunction is still occurring or occurred in the past and returned
to normal.
CONSULT-II can identify them. Therefore, using CONSULT-II (if available) is recommended.

HOW TO ERASE DTC

NLEC0627S02

How to Erase DTC (

With CONSULT-II)

NLEC0627S0201

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.)

SEF246Z

The emission related diagnostic information in the ECM can be erased by selecting “ERASE” in the “SELF-
DIAG RESULTS” mode with CONSULT-II.

How to Erase DTC (

Without CONSULT-II)

NLEC0627S0202

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. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See EC-1099.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.

If the battery is disconnected, the emission-related diagnostic information will be lost after approx.
24 hours.
