Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001530402
The Supplemental Restraint System such as “AIR 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 inoperative, 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 unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001315826
NOTE:
 This procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecting both battery cables with the ignition in the ″LOCK″
position.
 Always use CONSULT-II 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 power 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.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

DOOR LOCK FUNCTION
To ensure that the Intelligent Key works effectively, use within 100 cm range of each door, however the opera-
ble range may differ according to surroundings.
LOCK AND UNLOCK CONTROL
When door lock and unlock button of the Intelligent Key is pressed, lock signal or unlock signal is transmitted
from Intelligent Key to Intelligent Key unit.
When Intelligent Key unit receives the door lock and unlock signal, it operates door lock actuator.
SUPER LOCK OPERATION
Super lock provides a higher anti-theft performance than a conventional power door lock system. The super
lock system is controlled by BCM.
When super lock is set, all doors can not be opened from the inside.
ANTI-HIJACK MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock driver door. Pressing UNLOCK button
on Intelligent Key a second time within 5 seconds from the first time will unlock all doors and back door (hatch-
back) can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener
switch.
CONVENIENCE MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock all doors and back door (hatchback)
can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener switch.
NOTE:
Anti-hijack mode can be set to ON or OFF with CONSULT-III. Once OFF, the convenience mode will be active.
For setting information with CONSULT-III, refer to DLK-53, "
CONSULT-III Function (INTELLIGENT KEY)". For
setting information without CONSULT-III, refer to Owner's Manual.

DLK-252
< FUNCTION DIAGNOSIS >[WITH I-KEY & SUPER LOCK]
DOOR LOCK FUNCTION
If the following conditions are not satisfied, door lock and unlock operation is not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver and passenger door handles (1) and the back door request
switch (2). However, this operating range depends on the ambient
conditions.
DOOR LOCK AND UNLOCK CONTROL
When the Intelligent Key detects that door request switch is pressed, it starts corresponding with outside key
antenna (request switch pressed door). Then, the Intelligent Key is checked to be near the door.
If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and trans-
mits the key ID signal to the Intelligent Key unit. Intelligent Key unit receives the key ID signal and compares it
with the registered key ID. Intelligent Key unit sends door lock and unlock signal to BCM via CAN communica-
tion.
SUPER LOCK OPERATION
Super lock provides a higher anti-theft performance than a conventional power door lock system. The super
lock system is controlled by BCM and Intelligent Key unit.
When super lock is set, all doors cannot be opened from inside.
ANTI-HIJACK MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock driver door. Pressing UNLOCK button
on Intelligent Key a second time within 5 seconds from the first time will unlock all doors and back door (hatch-
back) can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener
switch.
CONVENIENCE MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock all doors and back door (hatchback)
can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener switch.
NOTE:
Anti-hijack mode can be set to ON or OFF with CONSULT-III. Once OFF, the convenience mode will be active.
For setting information with CONSULT-III, refer to DLK-53, "
CONSULT-III Function (INTELLIGENT KEY)". For
setting information without CONSULT-III, refer to Owner's Manual.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001396715
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
