Filament CheckAIS004RH
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester registers 0 or battery
voltage.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS003CB
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.
PrecautionsAIS003CC

Disconnect both battery cables in advance.

Disconnect air bag system line in advance.

Never tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

ual.

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-

harness connectors.
Precautions When Using CONSULT-IIAKS0058H
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
CHECK POINTS FOR USING CONSULT-II
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
–If YES, GO TO 2.
–If NO, GO TO 5.
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?
–If YES, GO TO 3.
–If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communica-
tion. Therefore, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-6, "
CAN Communication Unit" .
Precautions For Trouble DiagnosisAKS0058I
CAN SYSTEM

Do not apply voltage of 7.0 V or higher to the measurement terminals.

Use the tester with its open terminal voltage being 7.0 V or less.

Be sure to turn ignition switch off and disconnect negative battery terminal before checking the circuit.
