PRECAUTIONS

PRECAUTIONS PFP:00011 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT

BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat be lt , helps t o redu ce the r is k or sev erity of inj ury to the d river and fro nt pass enge r for certain types of collisi on . Thi s s ys te m in cl udes seat belt switch inp uts an d du al stag e front air bag modules. T he 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 whether the front occupants are belted or unbelted. Information ne ce ss ary t o se rv ice th e sy st em saf ely is i ncl u de d in the S RS and SB se ct i on of th is Ser vi ce Ma nual.

WARNING:

● To avoid rendering the SRS inoperativ e, which cou ld increase the risk of persona l 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 deale r.

● Improper maintenance , including incorrect removal and installation of the SRS, can le ad to per-

sonal injury caused by unintentional activati on of th e sy ste m. For removal of Spiral Ca ble an d Air Bag Module, see the SRS section.

● Do not use electrical test equipme nt on any circuit related to the SRS unless instructed to in this

Service Manual. SRS wiring ha rnesses can be identified by yellow and/or orange ha rnesses or harness connectors.

EKS00F55

General Precautions for Service Operations EKS000XN

● Never work with wet hands.

● Xenon headlamp in cl udes hi gh voltage gener ating part. Be su re

to disconnect battery negative cable (negative terminal) or power fuse before removing, installing, or touching the xenon headlamp (including lamp bulb).

● Turn the lighting switch OFF be fore dis connecti ng and connec t-

ing the connector.

● When turning the xeno n he ad la mp on an d wh il e it is illu mi na ted,

never touch the harness, bulb, and socket of the headlamp.

● When checking the headlamp on/off operation, check it on vehi-

cle and with the power connected to the vehicle-side connector.

● 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.

● Install the xenon headlamp bulb socket correctly. If it is installed

improperly, high-voltage leak or corona discharge may occur that can melt the bulb, connector, and housing. Do not illuminate the xenon headlamp bulb out of the headlamp housing. Doing so can cause fire and harm your eyes.

● When the bulb ha s burned out, wrap it in a thick viny l bag and

discard. Do not break the bulb.

● Leaving the bulb removed from the headlamp housing for long

period of time can deteriorate performance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when replacing the bulb.

● When adjusting the headlamp aiming, turn the aiming adjust-

ment screw only in the tightening direction. (If it is necessary to turn the screw in loosening direction, first fully loos en the screw, and then turn it in tightening direction.)

● Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

BAT TERY SAVER CONTROL

When the ignition switch is turned from ON (or START) to OFF (or ACC) positions while headlamps are illuminated, the RAP signal is supplied to terminal 10 of the headlamp battery saver control unit from BCM terminal

135. After counting 45 seconds by the RAP signal from the BCM to headlamp battery saver control unit, the ground supply to term in al 1 of t he h ea dlam p r e lay- 1 an d -2 f rom he ad la mp ba t te ry s av er c on tro l un it ter m in als 2 a nd 8 is terminated. Then the headlamps are turned off. The headlamps are turned off when driver or passenger side door is opened even if 45 seconds have not passed after ignition switch is turned from ON (or ST ART) to OFF (or ACC) positions while headlamps are illuminated. When the lighting switch is turned from OFF to 2ND after headlamps are turned to off by the battery saver control, ground is supplied

● to headlamp battery saver control unit terminals 5 and 13 from lighting switch terminal 11, and then,

● to headlamp relay-1 and 2 terminals 1 from headlamp battery saver control unit terminals 2 and 8

● through headlamp battery saver control unit terminals 3 and 9, and

● through light ing switch terminal 12.

Then headlamps illuminate again.

AUTO LIGHT OPER ATION

The auto light control system has an optical sensor inside it that detects outside brightness. When the lightin g switch is in AUTO position , it automatically turns on/off the parking (clearance) la mps and the headlamp s in accor dan ce wit h the am bien t li ght . Sensi tiv ity can be adju sted in four ste p s. For the d eta ils o f the setting, refer to LT-20, " When lighting switch is in “AUTO” position, ground is supplied

● to BCM terminal 14

● from lighting switch terminal 42.

When ignition switch is turn to “ON” or “START” position and Outside bri ghtness is darker than prescribed level, gr ound is supplie d

● to headlamp relay-1 and 2 terminals 1

● through headlamp battery saver control unit terminal 2, 8 and 4, 11, and

● to tail lamp relay terminal 1

● through headlamp battery saver control unit terminals 6, 14 and 4,1 1.

Then headlamp relay-1, 2 and tail lamp relay are energized, headlamps (low or high) and ta il lamps are illuminate according to switch position.

SETTING CHANGE FUNCTION FOR AUTO LIGHT SYSTEM" .

Shut Off Delay

While the headlam ps are lit in the auto-ligh t operation mo de, the ignitio n switch is turne d from “ON” to “OFF” position. The BCM no longer receives a voltage signal at terminal 68. This starts the auto light shut off delay timer . T he ti mer is set ba sed on the re sist anc e valu e at B CM term inal 6. Wi th the time r run ning , the he adla mp s remain lit. When the timer reaches the end of its cycle, the headlamps turn off. Headlamp lighting time can be adjusted from about 0 to 3 minutes. (This function is not applicable to the tail lamps.) Auto light shut off delay tim er can be adjusted in seven steps. For the detail s of the setting, refer to LT-20,

"SETTING CHANGE FUNCTION FOR AUTO LIGHT SYSTEM" .

VEHICLE SECURITY SYSTEM

The vehicle s ecurity syste m will flash the high be ams if the sy stem is trig gered. Refer t o BL-153, "VEHICLE

SECURITY (THEFT WARNING) SYSTEM" .

XENON HEADLAMP

Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead, they produce light when a high voltage current is passed between two tungsten electrodes through a mixture of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control of the power supply gives the headlamps stable quality and tone color. Followings are some of the many advantages of the xenon type headlamp.

● The light produced by the headlamps is white color approximating to sunlight that is ea sy on the eyes.

● Light output is nearly double that of halogen headlamps, affording increased area of illumination.

Revision; 2004 April 2003 Q45

LT-8

HEADLAMP (FOR USA)

● The light fe atures a high rel ative s pectral d istribu tion at wa veleng ths to th e human eye is most se nsitiv e,

which means that even in the rain, more light is reflected back from the road surface toward the vehicle, for added visibility.

● Power consumption is approxima tely 25 percent less than halogen headlamps, reducing battery load.

PARKING, LICENSE PLATE AND TAIL LAMPS PFP:26550 System Description EKS000TK

The parking, license and tail lamp operation is co ntrolled by the lighting s witch which is built into the s piral cable and BCM. The battery saver system is controlled by the head lamp battery saver control uni t and BCM. Power is supplied at all times

● to tail lamp relay terminals 2 and 6

● through 15A fuse [No. 54, located in the fuse, fusible link and relay block (J/B)], and

● to headlamp battery saver control unit terminal 7

● through 10A fuse [No. 6, located in the fuse block (J/B) NO.1].

When ignitio n switch is in ON or START position, power is supplied

● to headlamp battery saver control unit terminal 1

● through 10A fuse [No. 1, located in the fuse block (J/B) NO.1].

Ground is supplied

● to headlamp battery saver control unit terminals 4 and 11

● through body grounds M25 and M115.

LIGHTING OPERATION BY LIGHTING SWITCH
