1. CHECK “B” TERMINAL CIRCUIT
1. Turn ignition switch OFF.
2. Make sure that starter motor “B” terminal connection is clean
and tight.
3. Check voltage between starter motor “B” terminal and ground.
OK or NG
OK >> GO TO 2.
NG >> Check harness between battery and starter motor for open circuit.
2. CHECK BATTERY CABLE CONNECTION STATUS (VOLTAGE DROP TEST)
Check voltage between starter motor “B” terminal and battery posi-
tive terminal.
OK or NG
OK >> GO TO 3.
NG >> Check harness between the battery and the starter motor for poor continuity.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS0025I
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.
Service NoticeNIS0025J

When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.

Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or
damage them.

Apply sealing compound where necessary when installing parts.

When applying sealing compound, be careful that the sealing compound does not protrude from parts.

When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.
Precautions for WorkNIS0025K

When removing or disassembling each component, be careful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.

When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the compo-
nent with a shop cloth or vinyl tape to protect it.

Protect the removed parts with a shop cloth and keep them.

Replace a deformed or damaged clip.

If a part is specified as a non-reusable part, always replace it with new one.

Be sure to tighten bolts and nuts securely to the specified torque.

After re-installation is completed, be sure to check that each part works normally.

Follow the steps below to clean components.
–Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the
fouled area.
Then rub with a soft and dry cloth.
–Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub
with a soft and dry cloth.

Do not use organic solvent such as thinner, benzene, alcohol, and gasoline.

For genuine leather seats, use a genuine leather seat cleaner.
