PRECAUTIONS

PRECAUTIONS 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:
q 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 per-
formed by an authorized NISSAN/INFINITI dealer.
q Improper 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.
q 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
harness connectors.
General Precautions for Service Operations EKS00L4H

q Never work with wet hands.
q Turn the lighting switch OFF before disconnecting and connecting the connector.
q When checking the headlamp on/off operation, check it on vehicle and with the power connected to the
vehicle-side connector.
q Do 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.
q When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
q Leaving 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.
q Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.
Wiring Diagrams and Trouble Diagnosis EKS00L4I

When you read wiring diagrams, refer to the following:
q Refer to GI-15, "How to Read Wiring Diagrams" .
q Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" .
When you perform trouble diagnosis, refer to the following:
q Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
q Refer to GI-24, "How to Perform Efficient Diagnosis for an Electrical Incident" .

Component Parts and Harness Connector Location EKS00P7H

PKIC1218E

System Description EKS00P7I
J
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- LT
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. L
OUTLINE
Power is supplied at all times
M
q to ignition relay (located in IPDM E/R)
q to headlamp high relay (located in IPDM E/R) and
q to headlamp low relay (located in IPDM E/R), from battery directly,
q through 50A fusible link (letter G, located in fuse and fusible link box)
q to BCM terminal 57,
q through 20A fuse (No. 52, located in IPDM E/R) and
q through 20A fuse (No. 53, located in IPDM E/R)
q to CPU (located in IPDM E/R),
q through 10A fuse (No. 19, located in fuse and fusible link box)
q to combination meter terminal 3.
With the ignition switch in the ON or START position, power is supplied
q to ignition relay (located in IPDM E/R),
q through 10A fuse [No. 1, located in fuse block (J/B)]
q to BCM terminal 3,
q through 10A fuse [No. 14, located in fuse block (J/B)]

q to combination meter terminal 23
q through grounds M21, M80 and M83,
q to IPDM E/R terminals 38 and 59
q through grounds E21, E41 and E61.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R through the CAN communication. The CPU of the IPDM E/R controls
the headlamp low relay coil. When energized, this relay directs power
q through 15A fuse (No. 41, located in IPDM E/R)
q through IPDM E/R terminal 54
q to front combination lamp RH terminal 1,
q through 15A fuse (No. 40, located in IPDM E/R)
q through IPDM E/R terminal 52
q to front combination lamp LH terminal 1.
Ground is supplied
q to front combination lamp RH and LH terminals 3
q through grounds E21, E41 and E61.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R through the CAN
communication. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay
directs power
q through 10A fuse (No. 34, located in IPDM E/R)
q through IPDM E/R terminal 56
q to front combination lamp RH terminal 2,
q through 10A fuse (No. 35, located in IPDM E/R)
q through IPDM E/R terminal 55
q to front combination lamp LH terminal 2.
Ground is supplied
q to front combination lamp RH and LH terminals 3
q through grounds E21, E41 and E61.
With power and ground supplied, the high beam headlamps illuminate.
Combination meter that received high beam request signal by BCM through the CAN communication makes a
high beam indicator lamp turn on in combination meter.
FRIENDLY LIGHTING FUNCTION
This function starts timer function of BCM by operating passing switch, and illuminates headlamps (LOW
beam) for a given length of time.
Headlamps (LOW beam) stay ON for a given length of time by operating passing switch when ignition switch is
OFF and lighting switch is OFF.
Headlamps (LOW beam) stays ON for two minutes at a maximum by operating passing switch repeatedly.
CONSULT-II is capable of setting a lighting time. Refer to LT-16, "WORK SUPPORT" .
