Checking Fuel LinesNJFE0019Inspect fuel lines and tank for improper attachment, leaks, cracks,
damage, chafing and deterioration.
If necessary, repair or replace.

CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

Changing Fuel FilterNJFE0021REMOVALNJFE0021S011. Take out air duct and upper air cleaner case.
2. Remove fuel filter using a fuel filter wrench (commercial ser-
vice tool).
CAUTION:
Do not spill the fuel during removal. If the fuel is spilt, imme-
diately wipe it off. Be especially careful to prevent the fuel
from adhering to the insulators of the engine mounts.
3. Remove fuel-level warning sensor from fuel filter.
YFE008
INSTALLATIONNJFE0021S02Install in the reverse order of removal.
Tighten the fuel filter so that the sealing face contacts the
packing, then retighten it manually by approximately 2/3 turn.
After installation, operate the priming pump vertically to per-
form air bleeding.
Refer to FE-16, “Bleeding Fuel Filter”.

Bleeding Fuel FilterNJFE00231. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds.
To start the engine more quickly, crank the engine while pump-
ing the priming pump (requires two workers).
3. 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.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
NOTE:
When air is bled completely, pumping the priming pump sud-
denly becomes heavy.
Stop the operation at that time.
If it is difficult to bleed air by pumping the priming pump (the
priming pump does not become heavy during pumping), dis-
connect the fuel supply hose between the fuel filter and the
injection pump. Then, pump the priming pump up and down,
and make sure that fuel comes out. (Use a pan and be care-
ful not to spill fuel. Keep fuel clear of the engine.) After that,
connect the hose, then bleed air again.
DEF017
Checking Priming PumpNJFE0024Before checking priming pump, make sure that fuel filter is
filled with fuel.
1. Disconnect fuel return hose.
Place a suitable container beneath hose end.
2. Pump priming pump and check that the fuel overflows from the
hose end. If not, replace priming pump.
Removal and InstallationNJFE0015WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in workshop.
Be sure to furnish workshop with a CO
2fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
CAUTION:
Before removing fuel line parts, carry out the following procedures:
a) Put drained fuel in an explosion-proof container and put the lid on securely.
b) Disconnect battery ground cable.

2. Tighten flare nut to the specified torque, using a flare nut
wrench.
: 15 - 18 N·m (1.5 - 1.8 kg-m, 11 - 13 ft-lb)
CAUTION:
Be careful not to damage flare nut and clutch tube.
3. Install clutch hose to operating cylinder, and tighten mounting
bolts to the specified torque.
: 17 - 19 N·m (1.7 - 2.0 kg-m, 13 - 14 ft-lb)
4. After finishing the operation, bleed air from the clutch piping.
Refer to “Air Bleeding Procedure”, CL-10.

PRECAUTIONS
●Internal failure of stator roller clutch.
●Heavy clutch debris due to overheating (blue converter).
●Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
●The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
●The threads in one or more of the converter bolt holes are damaged.
●Transaxle failure did not display evidence of damaged or worn internal parts, steel particles or clutch plate
lining material in unit and inside the fluid filter.
●Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.
EURO-OBD SELF-DIAGNOSIS — EURO-OBD —
●A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the O/D OFF indicator lamp or the malfunction indicator (MI). Refer to the table on
AT- 4 2 , "
SELF-DIAGNOSTIC RESULT TEST MODE" for the indicator used to display each self-diagnostic
result.
●The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure AT- 3 9 , "
HOW TO ERASE DTC" to complete the repair and avoid
unnecessary blinking of the MI.
●The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when
the O/D OFF indicator lamp does not indicate any malfunctions.
–PNP switch
–A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of EURO-OBD, refer to AT-37, "
ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION" .
●Certain systems and components, especially those related to EURO-OBD, may use a new style
slide-locking type harness connector.
For description and how to disconnect, refer to EL-7, "HARNESS CONNECTOR".
Wiring Diagrams and Trouble DiagnosisECS007N9
When you read wiring diagrams, refer to the following:
●GI-12, "How to Read Wiring Diagrams".
