BCM (BODY CONTROL MODULE)
Normal status
• When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10ms.
Sleep status
• When BCM is in sleep mode, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low-cur-
rent-consumption mode. OUTPUTS (2, 3, and 4) turn ON-OFF at 60ms intervals, and receives lighting
switch input only.
CAN COMMUNICATION CONTROL
CAN communication allows a high rate of information through the two communication lines (CAN-L, CAN-H)
connecting the various control units in the system. Each control unit transmits/receives data, but selectively
reads required data only.
BCM STATUS CONTROL
BCM changes its status depending on the operation stat us in order to save power consumption.
1. CAN communication status • With ignition switch ON, CAN communicates with other control units normally.
• Control by BCM is being operated properly.
• When ignition switch is OFF, switching to sleep mode is possible.
• Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter isactive, CAN communication status is active.
2. Sleep transient status • This status shuts down CAN communication when ignition switch is turned OFF.
• It transmits sleep request signal to IPDM E/R and combination meter.
• Two seconds after CAN communication of all control units stops, CAN communication switches to inac-tive status.
3. CAN communication inactive status • With ignition switch OFF, CAN communication is not active.
• With ignition switch OFF, control performed only by BCM is active.
• Three seconds after CAN communication of all control units stops, CAN communication switches to
inactive status.
4. Sleep status • BCM is activated with low current consumption mode.
• CAN communication is not active.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005929267
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 incorrect 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 SRS 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 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005929268
NOTE:
• This procedure is applied only to models with Intell igent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
• Remove and install all control units after disconnec ting both battery cables with the ignition in the ″LOCK ″
position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS /IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.

OUTLINE
Functions available by operating the inside door lock and unlock switches
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are
unlocked.
Functions available by operating the front door lock assembly LH (key cylinder switch)
• Interlocked with the locking operation of front door lock assembly LH (key cylinder switch), door lock actua-
tors of all doors are locked.
• When front door lock assembly LH (key cylinder switch) is unlocked, front door lock assembly LH (actuator)
is unlocked.
• When front door lock assembly LH (key cylinder swit ch) is unlocked for the second time within 5 seconds
after the first operation, front door lock assembly RH (actuator), rear door lock actuator LH and rear door
lock actuator RH are unlocked.
Key reminder door system
When door lock and unlock switch is operated to lock doors with ignition key inserted in key cylinder and any
door open, all door lock actuators are locked and then unlocked.
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed.
Vehicle Speed Sensing Auto Door Lock*1
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 15 MPH (24 km/h) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door
lock has taken place, the BCM will relock all doors when the vehicle speed reaches 15 MPH (24 km/h) or more
again.
Setting change of Automatic Door Locks (LOCK) Function
The lock operation setting of the autom atic door locks function can be changed.
With CONSULT-III
The ON/OFF switching of the automatic door locks (LOC K) function and the type selection of the automatic
door locks (LOCK) function can be performed at the WO RK SUPPORT setting of CONSULT-III. Refer to BL-
41, "CONSULT-III Function (BCM)".
Without CONSULT- III
The automatic door locks (LOCK) function can be swit ched ON/OFF by performing the following operation.
