PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

NKS004HV

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 Battery Service

NKS0054A

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Precautions When Using CONSULT-II

NKS004HW

Use CONSULT-II CONVERTER when connecting CONSULT-II to data link connector.

CAUTION:

CAN communication does not function properly if CONSULT-II is used without connecting CONSULT-II
CONVERTER.

Precautions for Trouble Diagnosis

NKS004HX

CAUTION:

●

Never apply 7.0 V or more to the measurement terminal.

●

Use a tester with open terminal voltage of 7.0 V or less.

●

Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.

Precautions for Harness Repair

NKS004HY

●

Solder the repaired area and wrap tape around the soldered
area.

NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).

SKIB8766E

PRECAUTIONS

LAN-43

LAN

●

Bypass connection is never allowed at the repaired area.

NOTE:
Bypass connection may cause CAN communication error. The
spliced wire becomes separated and the characteristics of
twisted line are lost.

●

Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communi-
cation line.
