ILLUMINATION
System Description INFOID:0000000004306640
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil . This relay, when energized, directs power to the illu-
mination lamps, which then illuminate.
Power is supplied at all times
• to ignition relay, located in IPDM E/R,
• to tail lamp relay, located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70, and
• through 10A fuse [No. 8, located in fuse block (J/B)]
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• to ignition relay, located in IPDM E/R, and
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M57 and M61, and
• to IPDM E/R terminals 39 and 59
• through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH With the lighting switch in the 1ST or 2ND positi on, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicat ed to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power
• through 10A fuse (No. 37, located in IPDM E/R)
• through IPDM E/R terminal 29
• to microphone terminal 3 (with Bluetooth)
• to illumination control switch terminal 1
• to glove box lamp terminal 1 (with glovebox lamp)
• to audio unit terminal 9
• to front air control terminal 5
• to A/T device terminal 3 (with 4-speed A/T)
• to CVT device terminal 3 (with CVT)
• to hazard switch terminal 3
• to combination meter terminal 12
• to door mirror remote control switch terminal 16
• to combination switch (spiral cable) terminal 26 (with steering wheel audio control switches)
• to steering wheel audio control switches through combinat ion switch (spiral cable) terminal 18 (with steering
wheel audio control switches).
Ground is supplied
• to microphone terminal 2 (with Bluetooth)
• to glove box lamp terminal 2 (with glove box lamp), and
• to illumination control switch terminal 3
• through grounds M57 and M61.
The illumination control switch controls illuminat ion intensity by varying the ground to the following
• through illumination control switch terminal 2
• to audio unit terminal 8
• to front air control terminal 6

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004784384
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 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.
• 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 Wh eel Rotation After Battery Disconnect
INFOID:0000000004673030
NOTE:
• This Procedure is applied only to models with Inte lligent 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 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.
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 al l control units using CONSULT-III.
