Refer to PCS-39, "INTELLIGENT KEY : CONSUL T Function (BCM - INTELLIGENT KEY)"
.
>> GO TO 2.
2.PERFORM SELF-DIAGNOSTIC RESULT
Perform self diagnostic result.
Are any DTCs detected?
YES >> Refer to BCS-52, "DTC Index".
NO >> GO TO 3.
3.CHECK PUSH-BUTTON IGNITION SWITCH
Check push-button ignition switch.
Refer to PCS-76, "Component Function Check"
.
Is the operation normal?
YES >> GO TO 4.
NO >> Repair or replace malfunctioning parts.
4.CONFIRM THE OPERATION
Confirm the operation again.
Is the inspection normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951599
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.
