TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2006 July 2007 FX35/FX45
The Braking Distance is LongNFS000O0
CAUTION:
On slippery road surfaces, the stopping distance might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector E56 to deactivate ABS. In this condition,
check stopping distance. After inspection, connect connector.
OK or NG
OK >>
Bleed air from brake piping.

Check brake system.
NG >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "
Excessive ABS Function Operation Fre-
quency" .
The ABS Function Does Not OperateNFS000O1
CAUTION:
The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure warning lamp turns off approximately 2 seconds after the ignition switch is turned ON or when driv-
ing.
OK or NG
OK >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "Excessive ABS Function Operation Fre-
quency" .
NG >> Perform self-diagnosis. Refer to BRC-25, "
Self-Diagnosis" .
Pedal Vibration or ABS Operation Sound OccursNFS000O2
CAUTION:
Under the following conditions, when brake pedal is lightly depressed (just place a foot on it), ABS is
activated and vibration is felt. However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sound occurs when engine is started.
OK or NG
OK >> Perform self-diagnosis. Refer to BRC-25, "Self-Diagnosis" .
NG >> GO TO 2.
2. SYMPTOM CHECK 2
Check symptom when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur when the electrical component (head lamp, etc.) switches are operated?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to ABS actuator and electric unit (control unit) (or its wiring), and if there is, move it farther away.
NO >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "
Excessive ABS Function Operation Fre-
quency" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NBS003JN
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Liquid GasketNBS003JO
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 seal cutter is difficult to use, use a plastic ham-
mer 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 liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket 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.

COMBINATION METER ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter illumination is turned ON by unified meter control unit.
Nighttime Mode

Unified meter control unit is transferred to nighttime mode, with ignition switch turned ON and position
light request signal from BCM with CAN communication.

When nighttime mode, illumination control switch illumination
turns ON by unified meter control unit. Each illumination is con-
trolled by unified meter control unit.

UNIFIED METER AND A/C AMP
Revision: 2006 July 2007 FX35/FX45
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS00300

For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.

The unified meter and A/C amp. corresponds to a CONSULT-II function (self-diagnosis results, CAN diag-
nosis support monitor, data monitor).
COMBINATION METER CONTROL FUNCTION

Unified meter and A/C amp. receives necessary information for combination meter from each unit by CAN
communication.

Unified meter and A/C amp. transmits a signals with communication line (TX, RX) between unified meter
and A/C amp. and combination meter.
Input/output signals between unified meter and A/C amp. and combination meter.
NOTE:
Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to DI-8,

WARNING CHIME
Revision: 2006 July 2007 FX35/FX45
LIGHT WARNING CHIME
With ignition switch in LOCK or ACC position, driver's door is opened, and lighting switch in 1ST or 2ND posi-
tion, the light warning chime will sound.

BCM detects ignition switch in LOCK or ACC position, front door switch (driver side) ON, and lighting
switch in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to unified
meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter
with communication line.

When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" .
SEAT BELT WARNING CHIME
With ignition switch turned ON and driver's seat belt unfastened, seat belt warning chime will sound for
approximately 6 seconds.

Combination meter reads a ON/OFF signal from seat belt buckle switch (driver side), and transmits seat
belt buckle switch signal to unified meter and A/C amp. with communication line.

BCM receives seat belt buckle switch signal from unified meter and A/C amp. with CAN communication.

BCM detects ignition switch turned ON and seat belt buckle switch (driver side) ON. And then transmits
buzzer output signal (seat belt warning chime) to unified meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits buzzer output signal (seat belt warning chime) to combination
meter with communication line.

When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
NOTE:
When ignition key warning chime, light warning chime, and seat belt warning chime should be performed at
the same time, the priorities for each chime are the following.
1. Seat belt warning chime
2. Light warning chime
3. Ignition key warning chime
