Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)“AIR
BAG”and“SEAT BELT PRE-TENSIONER”
The Supplemental Restraint System “Air Bag” and “Seat Belt Pre-tensioner”, used along with a seat belt,
help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of an air bag module (located in the center of the steering wheel
and on the instrument panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sen-
sor unit, warning lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used
along with the seat belt help to reduce the risk or severity of injury to the driver and front passenger in a
side collision. The supplemental side air bag consists of air bag modules (located in the outer side of front
seats), satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal
collision), wiring harness, warning lamp (one of components of supplemental air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
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 dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses (except“SEAT BELT-TENSIONER”connector) can be
identified with yellow harness connector (and with yellow harness protector or yellow insulation
tape before the harness connectors). Not use electrical test equipment on any circuit related to
the SRS.
PRECAUTIONS AND PREPARATION

Description
HARNESS CONNECTOR (TAB-LOCKING TYPE)

The tab-locking type connectors help prevent accidental looseness or disconnection.

The tab-locking type connectors are disconnected by pushing or lifting the locking tab(s). Refer to the
illustration below.
Refer to the next page for description of the slide-locking type connector.
CAUTION:
Do not pull the harness or wires when disconnecting the connector.

HARNESS CONNECTOR
EL-6

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or lifting the slider. Refer to the illustra-
tion below.
CAUTION:
Do not pull the harness or wires when disconnecting the connector.
Be careful not to damage the connector support bracket when disconnecting the connector.
[Example]
SEL769V Waterproof type

1Firmly grasp shell of con-
nector housing at A.
2Push slider until
connector pops or
snaps apart.
3Disconnect harness
connector.
Non-waterproof type

1Firmly grasp shell
of connector hous-
ing at A.
2Pull back on the slider
while pulling apart
male and female
halves of connector.
3Disconnect harness
connector.
