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 Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this Service Manual WARNING: Always observe the following items for preventing accidental activation • To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision that 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 “SRS AIR BAG” • Never 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 C D E F G PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: Always observe the following items for preventing accidental activation • When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, never 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 minutes before performing any service H I J K L PG N O P Revision: 2012 November PG-3

to a driving condition and a battery condition, this model uses a charge/discharge capacity-enhanced battery Therefore, it is recommended to use a genuine battery when replacement is needed Revision: 2012 November PG-4 E26 COMPONENT PARTS < SYSTEM DESCRIPTION > Circuit Breaker INFOID:0000000008520354 A 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 temperature 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 B C D SEL109W Harness Connector INFOID:0000000008520356 E 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 F G H I J K L PG N O P Revision: 2012 November PG-5 E26 COMPONENT PARTS < SYSTEM DESCRIPTION > [Example] SEL769DA 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 disconnection • 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 Revision: 2012 November PG-6 E26 COMPONENT PARTS < SYSTEM DESCRIPTION > [Example] A B C D E F G H I SEL769V 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 connection CAUTION: J K L PG N O P Revision: 2012
