Self-DiagnosisNFS000OI
DESCRIPTION

If an error is detected in the system, ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp
on the combination meter turn on. In this case, perform self-diagnosis as follows:

While CONSULT-II is used, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp may be
turned on in a case of no malfunctioning.
OPERATION PROCEDURE
1. Turn ignition switch OFF.
2. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
3. Turn ignition switch ON.
4. Start engine and drive at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
5. After stopping vehicle, with the engine running, touch “ABS”, “SELF-DIAG RESULTS” in order on the CONSULT-II screen.
CAUTION:
If “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on the
ignition switch, “ABS” might not be displayed in the “SELECT SYSTEM” screen. In this case,
repeat the operation from step 1. If it can not be shown after several attempts, ABS actuator and
electric unit (control unit) may have malfunctioned.
6. The self-diagnostic results are displayed. (If necessary, the self-diagnostic results can be printed out by touching “PRINT”.)

When “NO FAILURE” is displayed, check ABS warning lamp, VDC OFF indicator lamp and SLIP indica-
tor lamp.
7. Perform the appropriate inspection from the display item list, and repair or replace the malfunctioning component.
8. Drive the vehicle at approximately 30 km/h (19 MPH) or more for approximately 1 minute. CAUTION:
In a case that a wheel sensor is malfunctioning, ABS warning lamp, VDC OFF indicator lamp, SLIP
indicator lamp will turn on. If vehicle is not driven at approximately 30 km/h (19 MPH) or more for
at least approximately 1 minute after repair of the wheel sensor system, ABS warning lamp, VDC
OFF indicator lamp and SLIP indicator lamp may not turn off even if everything is normal. Check
again to make sure that there is no malfunction on other parts.
ERASE MEMORY
1. Turn ignition switch OFF.
2. Start the engine and touch “ABS”, “SELF-DIAG RESULTS”, “ERASE MEMORY” in order on the CON- SULT-II screen to erase the error memory.
CAUTION:
If the error memory is not erased, re-conduct the operation from step 4.
3. Perform self-diagnosis again, and make sure that diagnostic memory is erased.
4. Drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp turn off.
NOTE:
VDC OFF switch should not stay “ON” position.

Removal and InstallationNFS000O4
REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the following when installing sensor.

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front wheel hub and bearing assembly and rear final drive. This is to avoid damage to
sensor wiring and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the following when installing sensor. Tighten installation bolts to specified torques.

When installing, make sure there is no foreign material such as iron chips on pick-up and mount-
ing hole of sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body panel). When installed, harness
must not be twisted. White line on harness must be visible from front.

DIAGNOSTIC WORKSHEET
Description
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MIL to come on steady or blink and
DTC to be detected. Examples:

Vehicle ran out of fuel, which caused the engine to misfire.

Fuel filler cap was left off or incorrectly screwed on, allowing fuel
to evaporate into the atmosphere.

PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45

When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.

Replace with new gasket, packing, oil seal or O-ring.

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.

Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.

Release air within route when refilling after draining engine coolant.

After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Precautions for Angle TighteningNBS003FT

Use the angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap bolts
–Crankshaft pulley bolt (No the angle wrench is required as bolt flange is provided with notches for angle
tightening)

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid GasketNBS003FU
REMOVAL OF LIQUID GASKET SEALING

After removing mounting nuts and bolts, separate the mating
surface using the seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap the seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where the seal cutter is difficult to use, use a plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver
is used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur- face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
