INFOID:0000000012433287
The Supplemental Restraint System such as “A IR 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 SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses 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 electri c 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 three minutes before performing any service.

Component Description
1. Accessory relay-2 • Accessory relay-2 is controlled by BCM.
• Accessory relay-2 supplies accessory power supply or ignition switch ACC signal to each ECU
when ignition switch is turned to ACC or ON.
• BCM compares status of accessory relay-2 control signal, and ignition switch position judged
by BCM.
2. BCM • BCM controls power distribution system.
• BCM judges ignition switch position by push-button ignition switch (push switch) and vehicle
condition.
• BCM checks ignition switch position internally.
3. Push-button ignition
switch Push-button ignition switch (push switch) is pressed, and transmits status signal to BCM and
IPDM E/R.
4. IPDM E/R • IPDM E/R detects push-button ignition switch (push switch) status, and transmits push-button
ignition switch status signal (CAN) to BCM.
• IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and ignition switch ON signal
(CAN) from BCM, and controls igniti on relay-1 (built into IPDM E/R)
5. Blower relay (in fuse
block) • Blower relay is controlled by BCM.
• Blower relay supplies ignition switch ON power supply or ignition switch ON signal to air con-
ditioning system when ignition switch is turned ON.
• BCM compares status of blower relay control signal and ignition switch position judged by BCM.
6. Accessory relay-1 (in
fuse block) • Accessory relay-1 is controlled by BCM.
• Accessory relay-1 supplies accessory power supply or ignition switch ACC signal to each ECU
when ignition switch is turned ACC or ON.
• BCM compares status of accessory relay-1 control signal, and ignition switch position judged by BCM.
7. Ignition relay-2 (in fuse
block) • Ignition relay-2 is controlled by BCM.
• Ignition relay-2 supplies ignition switch ON power supply or ignition switch ON signal to each
ECU and system when ignition switch is turned ON.
• BCM compares status of ignition relay-2 control signal and ignition switch position judged by
BCM.
• BCM monitors ignition relay-2 operating status by ignition relay feedback signal.
