Removal and InstallationINFOID:0000000012432359
CAUTION:
• Before servicing, turn the ignition
switch OFF, disconnect both battery terminals and wait at least
three minutes.
• Do not use air or electric tools when remo ving or installing the combination switch.
REMOVAL
1. Disconnect the negative and positive bat tery terminals, then wait at least three minutes. Refer to PG-70,
"Removal and Installation (Battery)".
2. Remove the steering column covers. Refer to IP-17, "
Removal and Installation".
3. Rotate steering wheel clockwise to access first combination switch screw (A) and remove.
4. Rotate steering wheel counter-clockwise to access second com- bination switch screw (A) and remove.
5. Disconnect the harness connector (B) from the combination switch (1) and remove.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• After the work is completed, make sure no system malfunction is detected by air bag warning lamp.
• In case a malfunction is detected by the air bag wa rning lamp, reset with the self-diagnosis function
and delete the memory with CONSULT.
• If a malfunction is still detected after the above operation, perform self-diagnosis to repair malfunc-
tions. Refer to BCS-58, "

PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012432360
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.

BODY CONTROL SYSTEM : System DescriptionINFOID:0000000012432363
OUTLINE
• BCM (Body Control Module) controls the various elec
trical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
• BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power c onsumption with the ignition switch OFF.
• BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various set- tings.

SYSTEM
OUTLINE
• BCM incorporates a power saving control function t
hat reduces the power consumption according to the
vehicle status.
• BCM switches the status (control mode) by itself wit h the power saving control function. It performs the sleep
request to each unit (IPDM E/R and combination mete r) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
• The reading interval of each switch changes from 10 ms interval to 60 ms interval.
SLEEP MODE ACTIVATION
• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful- filled.
• Each unit stops the transmission of CAN communication with the sleep wake-up signal. BCM is in CAN com- munication sleep mode.
• BCM is in the low power consumption mode and perform s the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
Sleep condition
WAKE-UP OPERATION
• BCM transmits the sleep wake up signal (wake up) to each unit when any of the wake-up conditions are ful- filled. It changes from the low power consumption mode to the normal mode.
• Each unit starts the transmission of CAN communica tion with the sleep wake up signal. Each unit transmits
the wake up signal to BCM via CAN communication to report the CAN communication start.
