PRECAUTIONS


PRECAUTIONS PFP:00011

Precautions for Supplemental Restraint System (SRS) AIR BAG and SEATBELT PRE-TENSIONER EKS005KV

The Supplemental Restraint System such as AIR BAG and SEAT BELT PRE-TENSIONER, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes 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 frontair bag, depending on the severity of a collision and whether 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: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 AirBag Module, see the SRS section.

q Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or

harness connectors.

General precautions for service operations EKS005KW

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 thevehicle-side connector.

q Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do nottouch 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 whenreplacing 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 EKS005KX

When you read wiring diagrams, refer to the following:

q Refer to GI-12, "How to Read Wiring Diagrams" in GI section.

q Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution in PG section.

When you perform trouble diagnosis, refer to the following:

q Refer to GI-10, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section.q Refer to GI-25, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section.

HEADLAMP (FOR USA)


HEADLAMP (FOR USA) PFP:26010

Component Parts and Harness Connector Location EKS0065X

System Description EKS0065Y

Control of the headlamp system operation is dependent upon the position of the combination switch (lightingswitch). When the lighting switch is placed in the 2ND position, the BCM receives input requesting the head-lamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent power distributionmodule engine room) across the CAN communication lines. The central processing unit of the IPDM E/R con-trols the headlamp high and headlamp low relay coils. When energized, these relays direct power to therespective headlamps, which then illuminate.

OUTLINE

Power is supplied at all times

q to headlamp high relay, located in the IPDM E/R (intelligent power distribution module engine room), and

q to headlamp low relay, located in the IPDM E/R (intelligent power distribution module engine room), and

q to BCM (body control module) terminal 55

q through 50A fusible link [letter j , located in the fuse and fusible link box]


q through 15A fuse [No. 3, located in the fuse block (J/B)].

With the ignition switch in the ON or START position, power is supplied



With the ignition switch in the ACC or ON position, power is supplied

q to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60

q through body grounds E9, E15 and E24.

Low Beam OperationWith the lighting switch in 2ND position, the BCM (body control module) receives input requesting the head-lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engineroom) across the CAN communication lines. The central processing unit of the IPDM E/R controls the head-lamp low relay coil. When energized, this relay directs power

q to 15A fuse [No. 36, located in the IPDM E/R]

q through terminal 20 of the IPDM E/R

q to terminal 1 of headlamp RH, and



q to terminal 1 of headlamp LH.

Ground is supplied at all timesq to terminal 2 of headlamp LH and RH


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 (body control module)receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R(intelligent power distribution module engine room) across the CAN communication lines. The central process-ing unit of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power



q to terminal 1 of headlamp RH, andq to 10A fuse [No. 38, located in the IPDM E/R]


q to terminal 1 of headlamp LH.


q to terminal 2 of headlamp LH and RH


With power and ground supplied, the high beam headlamps and the HIGH BEAM indicator illuminate.

BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turnedfrom ON or ACC to OFF, the battery saver control feature is activated.

Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lightingswitch) position is changed. If the combination switch (lighting switch) position is changed, then the headlampsare turned off.

AUTO LIGHT OPERATION

Refer to LT-41, "System Description" for auto light operation.

VEHICLE SECURITY SYSTEM (PANIC ALARM)

The vehicle security system (panic alarm) will flash the high beams if the system is triggered. Refer to BL-58,"Panic Alarm Operation" .

CAN Communication System Description EKS0065Z

The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the highbeam headlamps at approximately half illumination whenever the engine is running. If the parking brake isapplied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminateonce the parking brake is released. Thereafter, the daytime lights will continue to operate when the parkingbrake is applied.Battery saver system is controlled by the BCM.Power is supplied at all times

HEADLAMP OPERATION

Low Beam Operation

With the lighting switch in 2ND position, the BCM (body control module) receives input requesting the head-lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engineroom) across the CAN communication lines. The central processing unit of the IPDM E/R controls the head-lamp low relay coil. When energized, this relay directs power

q to 15A fuse (No. 45, located in the IPDM E/R)


q to terminal 1 of headlamp LH (low), and

q to 15A fuse (No. 36, located in the IPDM E/R)


q to terminal 1 of headlamp RH (low).


q to terminal 2 of headlamp LH (low) and RH (low)


With power and ground supplied, low beam headlamps illuminate.

High Beam Operation/Flash-to-Pass OperationWith the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM (body control module)receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R(intelligent power distribution module engine room) across the CAN communication lines. The central process-ing unit of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power

With power and ground supplied, the high beam headlamps and the HIGH BEAM indicator illuminate.

BATTERY SAVER CONTROL

With the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned fromON or ACC to OFF, the battery saver control feature is activated.Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lightingswitch) position is changed. If the combination switch (lighting switch) position is changed, then the headlampsare turned off.

AUTO LIGHT OPERATION

For auto light operation, refer to LT-41, "System Description" .

DAYTIME LIGHT OPERATION

With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, power issupplied

AUTO LIGHT SYSTEM PFP:28491

Component Parts and Harness Connector Location EKS005M1

System Description EKS005M2

Automatically turns on/off the parking lamps and the headlamps in accordance with ambient light.Timing for when the lamps turn on/off can be selected using four modes.

OUTLINE

The auto light control system uses an optical sensor that detects outside brightness.When the lighting switch is in AUTO position, it automatically turns on/off the parking lamps and the head-lamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the set-ting, refer to LT-49, "SETTING CHANGE FUNCTIONS" .Optical sensor ground is supplied

q from BCM (body control module) terminal 18

q to optical sensor terminal 3.

When ignition switch is turned to ON position and when outside brightness is darker than prescribed level,input is supplied


q from optical sensor terminal 4.

The headlamps will then illuminate. For a description of headlamp operation, Refer to LT-6, "System Descrip-tion" .

AUTO LIGHT SYSTEM


EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned fromON or ACC to OFF, and one of the front doors is opened, the battery saver control feature is activated.Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamp are turned off.Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

DELAY TIMER FUNCTION

When the ignition switch is ON and ACC is OFF while auto light switch is ON, the BCM turns on/off the head-

lamps. In delay timer function, auto timer sensor power source is OFF and BCM is not turned on/off by autosensor signal. On condition that:

q when the state is ignition switch ON or ACC is ON and output judgment by auto light function is headlampON turn to ignition switch ON or ACC are OFF and front door switch (driver side), front door switch (pas-senger side) is ON, output judgment by auto light function should be headlamp ON for 5 minutes by timer.After time out, output judgment by auto light function should be headlamp OFF.

q when the state is front door switch (driver side), front door switch (passenger side), rear door switch LH,rear door switch RH is turned to ON from OFF 45 seconds or 5 minutes while timer is counting, timerstops, and restarts counting for 5 minutes, then auto light function judges output as headlamp ON. Aftertime out, auto light function judges output as headlamp OFF.

q when the state is front door switch (driver side), front door switch (passenger side), rear door switch LH,rear door switch RH or back door switch is ON turns to front door switch (driver side), front door switch

(passenger side), rear door switch LH, rear door switch RH or back door switch are OFF 45 seconds or 5minute while is counting, timer stops, and restarts counting for 45 seconds, then auto light functionjudges output as headlamp ON. After timer out, auto light function judges output as headlamp OFF.

q when the state is ignition switch ON or ACC is ON or auto light switch OFF while timer is counting, timerstops counting and BCM turns on/off lamps according to headlamp function, front fog lamp function, autolight function and headlamp battery save function.

Delay timer control mode can be changed by the function setting of CONSULT-II.
