INSTALLATION
1. Note the following, and install O-rings to fuel injector.
CAUTION:

Upper and lower O-rings are different. Be careful not to confuse them.

Handle O-ring with bare hands. Do not wear gloves.

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel tube. Do not decenter or twist it.

Avoid fire and sparks.

Keep parts away from heat source. Especially, be careful when welding is performed around
them.

Do not expose parts to battery electrolyte or other acids.

Do not bend or twist connection between quick connector and fuel feed hose (with damper) dur-
ing installation/removal.

To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with

CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionBAS0007K

CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.

Refer to “CONSULT-II Software Operation Manual” for more information.
Function and System Application BAS0007L
x: Applicable
*1:Nissan Anti-Theft System
Nickel Metal Hydride Battery Replacement BAS0007M
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
