POWER SUPPLY AND GROUND CIRC
UIT FOR FRONT AIR CONTROL
DescriptionINFOID:0000000009463219
COMPONENT DESCRIPTION
Front air control.
The front air control has a built-in microcomputer that processes inform ation sent from various sensors
needed for air conditioner operation. The air mix door motor, the mode door motor, the intake door motor, the
blower motor and the A/C compressor are then controlled.
Component Function CheckINFOID:0000000009463220
1.CHECK OPERATION
1. Turn the blower motor dial clockwise and verify t he blower speed increases and that one of the LEDs illu-
minates on the mode switch.
2. Press the mode switches and verify that the modes change, the LEDs illuminate, and that air flows from
the various vents.
3. Turn the temperature control dial and verify the temperature changes at the selected vents.
4. Press the DEF and REC buttons and verify air flow changes.
Does it operate normally?
YES >> Inspection End.
NO >> Perform trouble diagnosis for the front air control system. Refer to HAC-152, "Diagnosis Proce-
dure".

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951592
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. 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 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct 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 SR 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 three minutes before performing any service.

Precaution for WorkINFOID:0000000009463859
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

System DiagramINFOID:0000000009463863
System DescriptionINFOID:0000000009463864
OUTLINE
• Front room/map lamps and personal lamps rear are controll ed by the room lamp timer control function of the
BCM when lamp switch is in the DOOR position.
• Front step lamps are controlled by step lamp control function of BCM.
• Trunk room lamp is controlled by trunk lamp control function of BCM.
• Push-button ignition switch illumination is controlled by the push-button ignition switch illumination control
function of BCM.
• Interior room lamps are illuminated by the welcome light function of Intelligent Key system. Refer to DLK-32,
"WELCOME LIGHT FUNCTION : System Description".
ROOM LAMP TIMER OPERATION
When the interior room lamp switch is in the DOOR position and when all conditions below are met, the BCM
begins timer control (maximum 30 seconds ) for interior room lamp ON/OFF.
• When the front door LH is unlocked [with Intelligent Key, main power window and door lock/unlock switch or
front door lock assembly LH (key cylinder switch)].
• When a door opens → closes.
Timer control is cancelled under the following conditions:
• When the front door LH is locked [with Intelligent Key, main power window and door lock/unlock switch or front door lock assembly LH (key cylinder switch)].
• A door is opened (door switch turns ON).
• Ignition switch is turned ON.
INTERIOR LAMP BATTERY SAVER CONTROL
If an interior lamp is left ON and does not turn OF F even when the doors are closed, the BCM turns off power
to the interior lamps automatically to save the batte ry 15 minutes after the ignition switch is turned OFF.

INTERIOR ROOM LAMP CONTROL SYSTEM
The BCM controls the following interior lamps:
• Front step lamp LH/RH
• Front room/map lamp LH/RH
• Personal lamp rear LH/RH
• Vanity mirror lamp LH/RH (if equipped)
• Trunk room lamp
After the battery saver system turns the la mps OFF, the lamps will illuminate again when:
• A signal is received from an Intelligent Key or main power window and door lock/unlock switch or when the front door lock assembly LH (key cylinder switch) is locked or unlocked.
• A door is opened or closed.
Revision: November 20132014 Altima NAMRevision: November 20132014 Altima NAM

INL-10
< SYSTEM DESCRIPTION >
ILLUMINATION CONTROL SYSTEM
• The BCM (body control module) receives the parking lamp request signal from the combination switch (light-
ing and turn signal switch) to turn the lights on.
• The BCM sends the parking lamp request signal to t he IPDM E/R (intelligent power distribution module
engine room) via CAN communication.
• IPDM E/R receives the parking lamp request signal from the BCM to activate the tail lamp relay and provide power to the illumination system.
BATTERY SAVER CONTROL
When the combination switch (lighting and turn signal switch) is in the 1st or 2nd position and the ignition
switch is set from ON or ACC to OFF, the battery save r control feature is activated. Under this condition, the
illumination system remains on for 15 minutes unless the combination switch (lighting and turn signal switch)
position is changed. If the combination switch (light ing and turn signal switch) position is changed, then the
illumination system is turned off after a 30 second delay . When the combination switch (lighting and turn signal
switch) is turned from OFF to 1st or 2nd position (or if auto light system is activated) after illumination system
has been turned off by the battery saver control, the illumination lights illuminate again.
