Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A

BELT PRE-TENSIONER"

AKS007KP

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B

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 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 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.

PRECAUTIONS

General Precautions for Service Operations

AKS004ZU

q Never work with wet hands.

q Xenon headlamp includes high voltage generating part. Be sure to disconnect battery negative cable (negative terminal) or power fuse before removing, installing, or touching the xenon headlamp (including lamp bulb).

q Turn the lighting switch OFF before disconnecting and connecting the connector.

q When turning the xenon headlamp on and while it is illuminated, never touch the harness, bulb, and socket of the headlamp.

q When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.

PKIA0183E

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 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.

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

EL-3422D

q When adjusting the headlamp aiming, turn the aiming adjustment screw only in the tightening direction. (If it is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.)

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

Wiring Diagrams and Trouble Diagnosis

AKS004ZV

When you read wiring diagrams, refer to the following: q Refer to GI-15, "How to Read Wiring Diagrams" in GI section. q Refer to PG-3, "POWER SUPPLY ROUTING CIRCUIT" for power distribution in PG section. When you perform trouble diagnosis, refer to the following: q Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" in GI section. q Refer to GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident" in GI section.

System Description

AKS007MA

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/ LT R (intelligent power distribution module engine room) across the CAN communication lines. CPU (central processing unit) of IPDM E/R (intelligent power distribution module engine room) controls the headlamp high and headlamp low relay coils. These relays, when energized, direct power to the respective headlamps, which L then illuminate. If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes out, and a high beam and a low beam are changed.

q to headlamp LH terminal 7

q through grounds E21, E50 and E51.

With power and ground supplied, the high beam headlamps illuminate. If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes

out, and a high beam and a low beam are changed.

The unified meter and A/C amp that received the high beam request signal by BCM across the CAN commu-

nication makes a high beam indicator lamp turn on in combination meter.

COMBINATION SWITCH READING FUNCTION

Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .

EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned

from ON or ACC to OFF, the battery saver control function is activated.

Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.

Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

AUTO LIGHT OPERATION (IF EQUIPPED)

Refer to LT-81, "System Description" in "AUTO LIGHT SYSTEM".

VEHICLE SECURITY SYSTEM

The vehicle security system will flash the high beams if the system is triggered. Refer to BL-216, "VEHICLE

SECURITY (THEFT WARNING) SYSTEM" .

XENON HEADLAMP

Xenon type headlamp is adopted to the low and high 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 J control of the power supply gives the headlamps stable quality and tone color.

Following are some of the many advantages of the xenon type headlamp.

q The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.

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

q The light features a high relative spectral distribution at wavelengths to which the human eye is most sen-

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

q Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.

CAN Communication System Description

AKS007MB

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

DAYTIME LIGHT SYSTEM turns on Daytime Light Lamps while driving. Day Light Lamps are not turned on if

engine is activated with Parking Brake on. Take off Parking Brake to turn on Daytime Light Lamps. The lamps turn off when Lighting Switch is in the 2ND position or AUTO position (Head Lamp is "ON") and when Lighting LT

Switch is in the PASSING position. (Daytime Light Lamps are not turned off only by Parking Brake itself.)

An parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-

nication line, and control daytime light system.

When outside brightness is darker than prescribed level, input is supplied q to BCM (body control module) terminal 14 q from optical sensor terminal 2. The headlamps will then illuminate. For a description of headlamp operation, refer to LT-81, "System Description" .

COMBINATION SWITCH READING FUNCTION Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the AUTO position, and the ignition switch is turned from ON or ACC to OFF, and one of the front door is opened, the battery saver control feature is activated. Under this condition, the headlamp remain illuminated for 5mimutes, 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 ignition switch ON and ACC are OFF while auto light switch is ON, BCM turn on/off headlamp. In delay timer function, auto timer sensor power source is OFF and BCM is not turned on/off by auto sensor signal. On condition that:
q when the states ignition switch ON or ACC is ON and output judgment by auto light function is headlamp ON turn to ignition switch ON or ACC are OFF and front door switch (driver side), front door switch (passenger side) is ON, output judgment by auto light function should be headlamp ON for 5 minutes by tamer. 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 or back door switch is turner to ON from OFF 45 seconds or 5 minutes while timer is counting, timer stops, and re-start counting for 5 minutes, then auto light function judges output as headlamp ON. After time out, auto light function judges output as headlamp OFF.
q when the states front door witch (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 witch (driver side), front door switch (passenger side), rear door switch LH, rear door switch RH or back door switch are OFF 45seconds or 5minute while is counting, Timer stops, and re-start counting for 45 seconds, then auto light function judges output as head lamp ON. After timer out, auto light function judges output as head lamp OFF.
q when the state is ignition switch ON or ACC is ON or auto light switch OFF while timer is counting, timer stops counting and BCM turns on/off lamps according to headlamp function, front fog lamp function, auto light function and headlamp battery save function.
Delay timer control mode can be changed by the function setting of CONSULT-II.

System Description

AKS007CI

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.When the lighting switch is placed in the fog lamp position the BCM (body control module) receives input signal LT requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R controls the front fog lamp relay coil. When activated, this relay directs L power to the front fog lamps.

OUTLINE

Power is supplied at all times

FRONT FOG LAMP

q to ignition relay [located in IPDM E/R (intelligent power distribution module engine room)] q through 15A fuse [No. 1 located in fuse block (J/B)] q to BCM (body control module) terminal 38. When the ignition switch is in ACC or ON position, power is supplied q through 10A fuse [No. 6, located in fuse block (J/B)] q to BCM (body control module) terminal 11. Ground is supplied q to BCM (body control module) terminals 49 and 52 q through grounds M35, M45 and M85 q to IPDM E/R (intelligent power distribution module engine room) terminals 38 and 60 q through grounds E21, E50 and E51.

Fog Lamp Operation The fog lamp switch is built into the combination switch. The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation. With the fog lamp switch in the ON position, the CPU (central processing unit) of the IPDM E/R (intelligent power distribution module engine room) grounds the coil side of the fog lamp relay. The fog lamp relay then directs power q through IPDM E/R terminal 37 q to front fog lamp LH terminal 1 q through IPDM E/R terminal 36 q to front fog lamp RH terminal 1. Ground is supplied q to front fog lamp LH terminal 2 q through grounds E21, E50 and E51, and q to front fog lamp RH terminal 2 q through grounds E21, E50 and E51. With power and grounds supplied, the front fog lamps illuminate.

COMBINATION SWITCH READING FUNCTION Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the fog lamp switch is ON, and the ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, then the fog lamps (and headlamps) are turned off. Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

System Description

AKS007DT

Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. CPU (central processing unit) of the IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay coil. This relay, when energized, directs power to the parking, license plate, side marker and tail lamps, which then illuminate. The current that flows by rear combination lamp unit is controlled, and a tail lamp (LED) is made to turn on. Power is supplied at all times
q through 10A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)]
q to tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)]
q through 15A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]
q to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)].
Power is also supplied at all times
q through 50A fusible link (letter M, located in fuse and fusible link block)
q to BCM (body control module) terminal 55
q through 15A fuse [No. 22, located in fuse block (J/B)]
q to BCM (body control module) terminal 42

ILLUMINATION

ILLUMINATION System Description

PFP:27545

AKS007EI

Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) B the BCM (body control module) receives input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The central processing unit of the IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay coil. This relay, when energized, directs power to the illumination C lamps, which then illuminate. Power is supplied at all times

q to tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)]

q through 10A fuse [No. 71, located in the IPDM E/R (intelligent power distribution module engine room)].

Power is also supplied at all times

With power and ground supplied, illumination lamps illuminate.

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is activated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated. Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are turned off. When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps are turned off by the battery saver control, and illumination lamps illuminate again. Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
