Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000006626861
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. Information necessary to service the system safely is included in the “SRS AIR BAG” and
“SEAT BELT” of this Service Manual.
The vehicle may be equipped with a passenger air bag deactivation switch. Because no rear seat exists where
a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a
rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and will not inflate. A passenger air bag OFF indicator on the instrument panel lights
up when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not affected
by the passenger air bag deactivation switch.
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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIR BAG”.
• 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 har-
ness connectors.
• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by
the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
will not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, make sure the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
vice.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, DO NOT use air or electric 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.

A/C UNIT ASSEMBLY
A/C UNIT ASSEMBLY : Thermo Control Amp.
INFOID:0000000006547915
• Thermo control amp. is composed of thermistor and amplifier. Thermistor is installed on evaporator, and
amplifier is attached to foot duct.
• When the thermistor detecting temperature of the evaporator fin is extremely low, thermo control amp. sends
the thermo control amp. OFF signal to BCM, and stops the compressor.
A/C UNIT ASSEMBLY : Blower Motor
INFOID:0000000006547916
• The blower motor utilizes a brush-less motor with a rotating mag-
net.
• Quietness is improved over previous motors where the brush was
the point of contact and the coil rotated.

A/C UNIT ASSEMBLY : Blower Fan Resistor
INFOID:0000000006547917
• Compact and lightweight resistor is adopted with outstanding venti-
lation.
• Temperature fuse is installed to protects the blower motor circuit.
A/C Control
INFOID:0000000006547918
Controls the air conditioning function.
BCM
INFOID:0000000006547919
BCM transmits A/C ON signal and blower fan ON signal to ECM via CAN communication, according to A/C
switch signal and blower fan ON signal that are received from A/C control and thermo control amp. signal that
is received from thermo control amp. and A/C indicator is turned ON.
ECM
INFOID:0000000006547920
ECM, when receiving A/C ON signal and blower fan ON signal from BCM, transmits A/C compressor request
signal to IPDM E/R via CAN communication according to status of the engine and refrigerant pressure.
IPDM E/R
INFOID:0000000006547921
A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when A/C compressor request signal is
received from ECM via CAN communication line.
Refrigerant Pressure Sensor
INFOID:0000000006547922
DESCRIPTION
• The refrigerant pressure sensor converts high-pressure side refrigerant pressure into voltage and outputs it
to ECM.
• ECM operates cooling system protection and idle speed control according to voltage value that is input.
STRUCTURE AND OPERATION
• The refrigerant pressure sensor is a capacitance type sensor. It consists of a pressure detection ares and a
signal processing area.
• The pressure detection area, which is a variable capacity condenser, changes internal static capacitance
according to pressure force.
• The signal processing area detects the static capacitance of the pressure detection area, converts the static
capacitance into a voltage value, and transmits the voltage value to ECM.
Magnet Clutch
INFOID:0000000006547923
Compressor is driven by the magnet clutch which is magnetized by electric power supply.

NOTE:
Compressor operational condition
• A/C switch signal: ON
• Blower fan ON signal: ON
• Thermo control amp. signal: ON
• ECM judges the conditions of each sensor (Refrigerant pressure sensor signal, accelerator position signal,
etc.), and transmits the A/C compressor request signal to IPDM E/R via CAN communication line.
• By receiving the A/C compressor request signal from ECM, IPDM E/R turns the A/C relay to ON, and acti-
vates the compressor.
Refer to
PCS-6, "RELAY CONTROL SYSTEM : System Description"
(with Intelligent Key system) or
38, "RELAY CONTROL SYSTEM : System Description"
(without Intelligent Key system).
CONTROL BY THERMO CONTROL AMP.
Low Temperature Protection Control
• When the thermo control amp. detects that evaporator fin tempera-
ture is 2
°
C (36
°
F) or less, thermo control amp. signal becomes
OFF, and stops the compressor.
• When the air temperature returns to 3.5
°
C (38
°
F) or more, the
compressor is activated.
CONTROL BY ECM
Compressor Protection Control at Pressure Malfunction
The high-pressure side value that is detected by refrigerant pressure sensor is as per the following state, ECM
requests IPDM E/R to turn A/C relay OFF and stop the compressor.
• 3.12 MPa (31.82 kg/cm
2
, 452.4 psi) or more (When the engine speed is less than 1,500 rpm)
• 2.74 MPa (27.95 kg/cm
2
, 397.3 psi) or more (When the engine speed is 1,500 rpm or more)
• 0.14 MPa (1.43 kg/cm
2
, 20.3 psi) or less
Compressor Oil Circulation Control
When the engine starts while the engine coolant temperature is 56
°
C (133
°
F) or less, ECM activates the com-
pressor for approximately 6 seconds and circulates the compressor oil once.
Air Conditioning Cut Control
When the engine condition is high load, ECM makes the A/C relay to OFF, and stops the compressor.
