Checking of Refrigerant LeaksINFOID:0000000005930884
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspec-
tion time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 to 50 mm (1 to 2 in) per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower an d closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorINFOID:0000000005930885
1. Check A/C system for leaks using the UV lamp and safety goggles J-42220 in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluoresce nt dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner J-43872 to prevent future misdiag- nosis.
4. Perform a system performance chec k and verify the leak repair with an approved electronic refrigerant
leak detector.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005929646
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 severity 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 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 NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect 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 SRS 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 3 minu tes before performing any service.

POWER SUPPLY ROUTING CIRCUIT
Fuse
INFOID:0000000005928339
• If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.
• Use fuse of specified rating. Never use fuse of more than specified
rating.
• Do not partially install fuse; always insert it into fuse holder prop- erly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not used for a long period of time.
Fusible LinkINFOID:0000000005928340
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
• If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted. In
such a case, carefully check and eliminate cause of malfunc-
tion.
• Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch an y other wiring harness, vinyl or
rubber parts.
Circuit Breaker (Built Into BCM)INFOID:0000000005928341
For example, when current is 30A, t he circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
• Power windows
• Power sunroof
Circuit BreakerINFOID:0000000005928342
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE
ROOM)
System DescriptionINFOID:0000000005928343
• IPDM E/R (Intelligent Power Distribution Module Engi ne Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relays via IPDM E/R control cir-
cuits.
• IPDM E/R-integrated control circuits perform ON-OFF operation of relays, CAN communication control, oil pressure switch signal reception, etc.
• It controls operation of each electrical co mponent via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R integr ated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
1. Lamp control
Using CAN communication lines, it receives signals from the BCM and controls the following lamps:
• Headlamps (High, Low)
• Parking lamps
• Tail and license plate lamps
• Front fog lamps
2. Wiper control Using CAN communication lines, it receives signals from the BCM and controls the front wipers.
3. Rear window defogger relay control Using CAN communication lines, it receives signals from the BCM and controls the rear window defogger
relay.
4. A/C compressor control Using CAN communication lines, it receives signal s from the ECM and controls the A/C compressor
(magnet clutch).
5. Starter control Using CAN communication lines, it receives signals from the BCM and controls the starter relay.
6. Cooling fan control Using CAN communication lines, it receives signals from the ECM and controls the cooling fan relays.
7. Horn control Using CAN communication lines, it receives signals from the BCM and controls the horn relay.
8. Daytime light system control (Canada only) Using CAN communication lines, it receives signals from the BCM and controls the daytime light relay.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L-line, CAN
H-line), it is possible to transmit a maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
1. Fail-safe control • When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control.
After CAN communication returns to normal operation, it also returns to normal control.
• Operation of control parts by IPDM E/ R during fail-safe mode is as follows:
Controlled system Fail-safe mode
Headlamp • With the ignition switch ON, headlamp low relay is ON, headlamp high relays are OFF, and
daytime light system (Canada only) is OFF.
• With the ignition switch OFF, the headlamp relays are OFF.
Tail, license plate and parking lamps • With the ignition switch ON, the tail lamp relay is ON. • With the ignition switch OFF, the tail lamp relay is OFF.
Cooling fan • With the ignition switch ON, cooling fan relay-1, relay-2, and relay-3 are ON.
• With the ignition switch OFF, all cooling fan relays are OFF.
Front wiper Until the ignition switch is turned off, the front wiper relays remain in the same status they
were in just before fail
−safe control was initiated.
