PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AIS004L9
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. 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 whether 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 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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectAIS00583
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 knob 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.
Precautions for WorkAIS004LA

After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.

Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION
Door lock/unlock operation is necessary for all doors close.
Map Lamp And Keyhole Illumination Function
When the following conditions come:

condition of map lamp switch is DOOR position;

door switch OFF (when all the doors are closed);
Remote control button of Intelligent Key turns on interior lamp (for 30 seconds) with input of UNLOCK signal
from Intelligent Key.
Panic Alarm Function
When key switch is OFF and ignition knob is not pushed (when mechanical key is not inserted in ignition
knob), BCM turns ON and OFF horn and headlamp intermittently with input of PANIC ALARM signal from
Intelligent Key. The alarm automatically turns off after 25 seconds or when Intelligent Key unit receives any
signal from Intelligent Key.
Panic alarm operation mode can be changed using “WORK SUPPORT” mode in “PANIC ALARM DELAY”.
Refer to BL-120, "
WORK SUPPORT" .
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with ignition switch OFF, and Intelligent Key unlock switch is
detected to be on continuously for 3 seconds, the driver's door and passenger's door power windows are
simultaneously opened.
Power window is operated to open and the operation continues as long as the Intelligent Key unlock switch is
pressed.
Remote control power window down operation mode can be changed using “P/W DOWN DELAY” mode in
“WORK SUPPORT”. Refer to BL-120, "
WORK SUPPORT" .
Key Reminder Function
As an operation verification function, when doors are locked or unlocked using Intelligent Key remote control-
ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description

When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID
verification is conducted with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)

When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights
up red.

When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses
CAN communication to send engine start permission signal to BCM.

When BCM receives engine start permission signal, it uses CAN communication to sent starter request
signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
