SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005929026
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 severi ty 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 inoper ative, 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 unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied 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 Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric 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 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000005929027
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng both battery cables with the ignition knob 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 NATS , an electrically controlled steering lock mech-
anism 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.

Headlamp operation is controlled by the BCM (body c ontrol module) based on inputs from the combination
switch (lighting and turn signal switch). When the light ing switch is placed in the 2ND position, the BCM
receives an input signal requesting the headlamps (and tail lamps) illuminate. The BCM sends a signal, via the
CAN communication lines, to the IPDM E/R (intelligent power distribution module engine room) requesting the
headlamps be turned ON. The CPU (centra l processing unit) located in the IPDM E/R controls ground for the
headlamp high and headlamp low relay coils. These relays direct power to the respective headlamps, which
then illuminate.

lamp low relay coils. These relays direct power to the respective headlamps, which then illuminate. When the
headlamp switch is OFF or in the 1ST position (parking lamps ON), the parking brake is released and the
engine is running, the IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light
relay 1 to actuate the daytime light function.

HEADLAMP OPERATION
Low Beam Operation
With the lighting switch in 2ND position, the BCM re ceives an input signal requesting the headlamps to illumi-
nate. This input signal is communicated to the IPDM E/R via the CAN communication lines. The CPU located
in the IPDM E/R controls the headlamp low re lay coil, which when energized, directs power
• through 15A fuse (No. 41, located in IPDM E/R)
• through IPDM E/R terminal 54
• to daytime light relay 2 terminals 1 and 5 (energizing the relay),
• through daytime light relay 2 terminal 3
• to front combination lamp RH terminal 3, and
• through 15A fuse (No. 40, located in IPDM E/R)
• through IPDM E/R terminal 52
• to front combination lamp LH terminal 3.
Ground is supplied
• to front combination lamp LH terminal 2
• through grounds E15 and E24,
• to headlamp RH terminal 2 via
• daytime light relay 1 terminals 3 and 4
• through grounds E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam/Flash-to-Pass Operation
With the lighting switch in 2ND position and high beam s witch in the HIGH position, the BCM receives input
signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and
also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination
meter via the CAN communication lines. The CPU locat ed in the IPDM E/R controls the headlamp high relay
coil, which when energized, directs power
• through 10A fuse (No. 34, located in IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 1, and
• through 10A fuse (No. 35, located in IPDM E/R)
• through IPDM E/R terminal 55
• to front combination lamp LH terminal 1.
Ground is supplied
• to front combination lamp LH terminal 2
• through grounds E15 and E24, and
• to front combination lamp RH terminal 2 via
• daytime light relay 1 terminals 3 and 4
• through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power
• from daytime light relay 1 terminal 3
• to front combination lamp RH terminal 2,
• through front combination lamp RH high beam terminal 1
