POWER SUPPLY AND GROUND CIRCUIT FOR FRONT AIR CONTROL
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".
Diagnosis ProcedureINFOID:0000000009463221
Regarding Wiring Diagram information, refer to HAC-130, "Wiring Diagram".
1.CHECK FRONT AIR CONTROL POWER SUPPLY
1. Turn ignition switch OFF.
2. Disconnect the front air control connector.
3. Turn ignition switch ON.

PRECAUTIONS
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.

< SYSTEM DESCRIPTION >
COMPONENT PARTS
IPDM E/RThe IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication.
Push button ignition switch Provides ignition switch status to the BCM.
Door switches Provides door OPEN/CLOSED status to the BCM.
Combination switch
(lighting and turn signal switch) The combination switch (lighting and turn signal switch) provides
input to the BCM. The BCM then sends a tail lamp relay request
signal to the IPDM E/R via CAN communication to operate the il-
lumination system.
Trunk lamp switch and release solenoid
(trunk lamp switch) Provides trunk lamp switch OP
EN/CLOSED status to the BCM.
Power window and door lock/unlock switch RH Provides door lock/unlock position switch RH status to the BCM.
Main power window and door lock/unlock switch Provides door lock/unlock position switch LH status to the BCM.
Meter control switch
(illumination control switch) • Adjusts the illumination system and combination meter illumina-
tion brightness (with multiple illumination control).
• Only adjusts the combination meter illumination brightness
(with meter illumination control only).
Front door lock assembly LH (key cylinder switch) Provides front door lock assembly LH (key cylinder switch) door
lock/unlock switch position status to the BCM.
