DTC Confirmation ProcedureNBS004EK
CAUTION:
Always drive vehicle at a safe speed.
NOTE:

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.

Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for
malfunction B. By performing procedure for malfunction A, the incident that causes malfunction B can be
detected.
TESTING CONDITION:
Steps 4 and 5 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1. Start engine (VDC switch OFF).
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Press MAIN switch and make sure that CRUISE lamp lights up.
4. Drive the vehicle for at least 5 consecutive seconds under the following conditions.
If 1st trip DTC is detected, go to EC-1214, "
Diagnostic Proce-
dure" .
If 1st trip DTC is not detected, go to the following step.

FUEL INJECTOR AND FUEL TUBE
Revision: 2006 December 2006 FX35/FX45

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as follows: (Unless otherwise indicated, the installation to the engine side and centralized under-floor piping side is exactly alike.)
a. Make sure no foreign substances are deposited in and around fuel tube and quick connector, and no dam- age on them.
b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube. Engine side:

Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:

Hold “A” position as shown in the figure when inserting
fuel tube into quick connector.

Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.

Insert until you hear a “click” sound and actually feel the
engagement.

To avoid misidentification of engagement with a similar sound, be sure to perform the next step.
Centralized under-floor piping side:

Visually confirm that the two retainer tabs are connected to the connector.
CAUTION:

Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick con-
nector.

Insert until you hear a “click” sound and actually feel the engagement.

To avoid misidentification of engagement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
e. Install quick connector cap on quick connector connection. CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed correctly. Check connection again.
f. Install fuel feed hose to hose clamps.
7. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
