PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EKS00N1L
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 and SB section of
this Service Manual.
WARNING:
lTo 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 per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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
harness connectors.
General Precautions for Service OperationsEKS00L4H
lNever work with wet hands.
lTurn the lighting switch OFF before disconnecting and connecting the connector.
lWhen checking the headlamp on/off operation, check it on vehicle and with the power connected to the
vehicle-side connector.
lDo not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not
touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
lWhen the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
lLeaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor-
mance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when
replacing the bulb.
lDo not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
Wiring Diagrams and Trouble DiagnosisEKS00L4I
When you read wiring diagrams, refer to the following:
lRefer toGI-15, "How to Read Wiring Diagrams".
lRefer toPG-4, "POWER SUPPLY ROUTING CIRCUIT".
When you perform trouble diagnosis, refer to the following:
lRefer toGI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES".
lRefer toGI-24, "How to Perform Efficient Diagnosis for an Electrical Incident".

HEADLAMP -CONVENTIONAL TYPE-PFP:26010
Component Parts and Harness Connector LocationEKS00P7H
System DescriptionEKS00P7I
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives
input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intel-
ligent power distribution module engine room) through the CAN communication. The CPU (central processing
unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays
direct power to the respective headlamps, which then illuminate.
OUTLINE
Power is supplied at all times
lto ignition relay (located in IPDM E/R)
lto headlamp high relay (located in IPDM E/R) and
lto headlamp low relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 10A fuse (No. 19, located in fuse and fusible link box)
lto combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
lto ignition relay (located in IPDM E/R),
lthrough 10A fuse [No. 1, located in fuse block (J/B)]
lto BCM terminal 3,
lthrough 10A fuse [No. 14, located in fuse block (J/B)]
