CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionEAS000G8

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 EAS000G9
x: Applicable
*1: Nissan Anti-Theft System
*2: Gasoline engine models
Nickel Metal Hydride Battery Replacement EAS000GA
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.

Removal and Installation (QR20DE)EBS00KNH
CAUTION:
Do not remove or disassemble parts unless instructed as shown in the figure.
REMOVAL
1. Release fuel pressure. Refer to EC-48, "FUEL PRESSURE RELEASE" (WITH EURO-OBD) or EC-510,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
2. Remove air cleaner case upper, mass air flow sensor and air duct assembly. Refer to EM-15, "
AIR
CLEANER AND AIR DUCT" .
3. Disconnect quick connectors at engine side and vehicle side as
follows, and remove fuel feed hose.
CAUTION:
Disconnect quick connector by using quick connector
release (special service tool), not by picking out retainer
tabs.
NOTE:
There is quick connector for the engine side and for the vehicle
side, and they have different shapes. But disconnection is same
procedure. The following procedure shows the engine side.
a. Remove quick connector cap (engine side).
1. Fuel feed hose 2. Quick connector cap (engine side) 3. Quick connector cap (vehicle side)
4. Centralized under-floor piping 5. Sub-harness 6. Fuel tube protector

b. With the sleeve side of quick connector release facing quick connector, install quick connector release
onto fuel tube.
c. Insert quick connector release into quick connector until sleeve
contacts and goes no further. Hold quick connector release on
that position.
CAUTION:
Inserting quick connector release hard will not disconnect
quick connector. Hold quick connector release where it
contacts and goes no further.
d. Draw and pull out quick connector straight from fuel tube.
CAUTION:

Pull quick connector holding “A” position in the figure.

Do not pull with lateral force applied. O-ring inside quick
connector may be damaged.

Prepare container and cloth beforehand as fuel will leak out.

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 during installa-
tion/removal.

To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
4. Remove PCV hose. Refer to EM-17, "
Removal and Installation (QR20DE)" .
5. Disconnect harness connector from ignition coil.
6. Remove sub-harness for fuel injector.
7. Remove electric throttle control actuator and intake manifold support. Refer to EM-17, "
Removal and
Installation (QR20DE)" .
8. Loosen mounting bolts in reverse order as shown in the figure.
9. Remove fuel tube protector.
10. Pull out fuel tube and fuel injector assembly rearward of engine.
CAUTION:

When removing, be careful to avoid any interference with fuel injector.

Use a shop cloth to absorb any fuel leaks from fuel tube.
