Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951561
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 severi ty 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 NISS AN/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.
Precaution for WorkINFOID:0000000009460817
• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009955247
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
BCM can perform the following functions.
Direct Diagnostic Mode Description
Ecu Identification The BCM part number is displayed.
Self Diagnostic Result The BCM self diagnostic results are displayed.
Data Monitor The BCM input/output data is displayed in real time.
Active Test The BCM activates outputs to test components.
Work support The settings for BCM functions can be changed.
Configuration • The vehicle specification can be read and saved.
• The vehicle specification can be written when replacing BCM.
