Nissan Juke (2012 year). Service Repair Manual - part 176

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 SR 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 performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR 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 har-
ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

SYSTEM DESCRIPTION

COMPONENT PARTS

Circuit Breaker

INFOID:0000000007578546

The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

Battery

INFOID:0000000007578547

: Because of the frequent battery charge/discharge performed according to a driving condition and a bat-

tery condition, this model uses a charge/discharge capacity-enhanced battery. Therefore, it is recommended
to use a genuine battery when replacement is needed.

Harness Connector

INFOID:0000000007578548

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 figure

below.

CAUTION:

Never pull the harness or wires when disconnecting the connector.

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 disconnec-

tion.

• The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the figure

below.

CAUTION:

• Never pull the harness or wires when disconnecting the connector.
• Be careful not to damage the connector support bracket when disconnecting the connector.

HARNESS CONNECTOR (LEVER LOCKING TYPE)

• Lever locking type harness connectors are used on certain control units and control modules such as ECM,

ABS actuator and electric unit (control unit), etc.

• Lever locking type harness connectors are also used on super multiple junction (SMJ) connectors.
• Always confirm the lever is fully locked in place by moving the lever as far as it will go to ensure full connec-

tion.
