4 PRECUTIONS PRECUTIONS PFP:00011 Precautions for Supplemental Restraint System (SRS) IR G and SET ELT PRE-TENSIONER EKS008LD The Supplemental Restraint System such as IR G and SET ELT 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. 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 S section of this Service Manual. WRNING: 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 performed by an authorized NISSN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and ir ag Module, see the SRS section. 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 Never work with wet hands. The xenon headlamp system includes a high voltage generating part. e sure 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 before disconnecting and connecting the connector. When turning the xenon headlamp on and while it is illuminated, never touch the harness, bulb, and socket of the headlamp. When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector. PKI0183E 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 has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb. 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). lways prepare a new bulb and have it on hand when replacing the bulb. EL-3422D 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.) Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant. EKS008LE LT-4

5 HEDLMP (FOR US) HEDLMP (FOR US) Component Parts and Harness Connector Location PFP:26010 EKS008LG C D E F G H I J System Description WKI4084E 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 CM (body control module) receives input requesting the headlamps (and tail lamps) to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CN communication lines. 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 to headlamp high relay, located in the IPDM E/R, and to headlamp low relay, located in the IPDM E/R, and through 50 fusible link (letter f, located in the fuse and fusible link box) to CM terminal 70. With the ignition switch in the ON or STRT position, power is supplied through 10 fuse [No. 1, located in the fuse block (J/)] to CM terminal 38. With the ignition switch in the CC or ON position, power is supplied through 10 fuse [No. 6, located in the fuse block (J/)] to CM terminal 11. Ground is supplied EKS008LH LT L M LT-5

6 HEDLMP (FOR US) to CM terminal 67 through grounds F14, M57 and M61. Low eam Operation With the lighting switch in 2ND position, the CM receives input requesting the headlamps to illuminate. This input is communicated to the IPDM E/R across the CN communication lines. The CPU of the IPDM E/R controls the headlamp low relay coil. When energized, this relay directs power through 15 fuse (No. 36, located in the IPDM E/R) through IPDM E/R terminal 20 to headlamp RH terminal 1, and through 15 fuse (No. 45, located in the IPDM E/R) through IPDM E/R terminal 30 to headlamp LH terminal 1. Ground is supplied to headlamp RH terminal 2 to headlamp LH terminal 2 through grounds E15 and E24. With power and ground supplied, low beam headlamps illuminate. High eam Operation/Flash-to-Pass Operation With the lighting switch in 2ND position and placed in HIGH or PSS position, the CM receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CN communication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH EM indicator. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power through 10 fuse (No. 40, located in the IPDM E/R) through IPDM E/R terminal 27 to headlamp RH terminal 1, and through 10 fuse (No. 38, located in the IPDM E/R) through IPDM E/R terminal 28 to headlamp LH terminal 1. Ground is supplied to headlamp RH terminal 2 to headlamp LH terminal 2 through grounds E15 and E24. With power and ground supplied, the high beam headlamps illuminate. TTERY SVER CONTROL When the combination switch (lighting switch) is in the 2ND position (ON) and the ignition switch is turned from ON or CC to OFF, the battery saver control feature is activated. Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps are turned off. UTO LIGHT OPERTION Refer to LT-43, "System Description" for auto light operation. XENON HEDLMP (IF EQUIPPED) The low beam headlamps may be equipped with xenon type bulbs. 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. Following are some of the advantages of the xenon type headlamp. The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes. Light output is nearly double that of halogen headlamps, affording increased area of illumination. LT-6

7 HEDLMP (FOR US) The light features a high relative spectral distribution at wavelengths to which the human eye is most sensitive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle for added visibility. Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load. CN Communication System Description Refer to LN-20, "CN COMMUNICTION".

If the parking brake is applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking brake is applied. attery saver system is controlled by the CM (body control module). Power is supplied at all times to headlamp high relay located in the IPDM E/R (intelligent power distribution module engine room), and through 50 fusible link (letter f, located in the fuse and fusible link box) to CM terminal 70. LT-32

33 HEDLMP (FOR CND) - DYTIME LIGHT SYSTEM - With the ignition switch in the ON or STRT position, power is supplied through 10 fuse [No. 12, located in the fuse block (J/)] to daytime light control unit terminal 3, and through 10 fuse [No. 1, located in the fuse block (J/)] to CM terminal 38. With the ignition switch in the CC or ON position, power is supplied through 10 fuse [No. 6, located in the fuse block (J/)] to CM terminal 11. With the ignition switch in the STRT position, power is supplied through 10 fuse [No. 9, located in the fuse block (J/)] to daytime light control unit terminal 2. Ground is supplied to daytime light control unit terminals 13, 14 and 16 through grounds E15 and E24, and to CM terminal 67 through grounds F14, M57 and M61. HEDLMP OPERTION Low eam Operation With the lighting switch in 2ND position, the CM receives input requesting the headlamps to illuminate. This input is communicated to the IPDM E/R across the CN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp low relay coil. When energized, this relay directs power through 15 fuse (No. 36, located in the IPDM E/R) through IPDM E/R terminal 20 to RH headlamp terminal 1, and through 15 fuse (No. 45, located in the IPDM E/R) through IPDM E/R terminal 30 to LH headlamp terminal 1. Ground is supplied to RH headlamp terminal 2 to LH headlamp terminal 2 through grounds E15 and E24. With power and ground supplied, low beam headlamps illuminate. High eam Operation/Flash-to-Pass Operation With the lighting switch in 2ND position and placed in HIGH or PSS position, the CM receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CN communication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH EM indicator. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power through 10 fuse (No. 40, located in the IPDM E/R) through IPDM E/R terminal 27 to daytime light control unit terminal 4 through daytime light control unit terminal 7 to RH headlamp terminal 1, and through 10 fuse (No. 38, located in the IPDM E/R) through IPDM E/R terminal 28 to daytime light control unit terminal 5 through daytime light control unit terminal 6 to LH headlamp terminal 1.

With power and ground supplied, the high beam headlamps illuminate. TTERY SVER CONTROL With the combination switch (lighting switch) is in the 2ND position (ON) and the ignition switch is turned from ON or CC to OFF, the battery saver control feature is activated. Under this condition, the headlamps remain illuminated for 5 minutes unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps are turned off. UTO LIGHT OPERTION For auto light operation, refer to LT-43, "System Description". DYTIME LIGHT OPERTION With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, power is supplied through daytime light control unit terminal 7 to RH headlamp terminal 1 through RH headlamp terminal 2 to daytime light control unit terminal 9, and through daytime light control unit terminal 6 to LH headlamp terminal 1 through LH headlamp terminal 2 to daytime light control unit terminal 10. Ground is supplied to daytime light control unit terminals 13, 14 and 16 through grounds E15 and E24. ecause the high beam headlamps are now wired in series, they operate at half illumination. XENON HEDLMP (IF EQUIPPED) The low beam headlamps may be equipped with xenon type bulbs. 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. Following are some of the advantages of the xenon type headlamp. The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes. Light output is nearly double that of halogen headlamps, affording increased area of illumination. The light features a high relative spectral distribution at wavelengths to which the human eye is most sensitive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle for added visibility. Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load. OPERTION fter starting the engine with the lighting switch in the "OFF" or 1ST position, the headlamp high beam automatically turns on. Lighting switch operations other than the above are the same as conventional light systems. LT-34

59 FRONT FOG LMP FRONT FOG LMP Component Parts and Harness Connector Location PFP:26150 EKS0085 C D E F G H I System Description WKI4087E EKS008MP Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the UTO position (with auto light system) or headlamps position (LOW beam is ON) for front fog lamp operation. When the lighting switch is placed in the fog lamp position, the CM (body control module) receives input requesting the fog lamps to illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CN communication lines. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When energized, this relay directs power to the front fog lamps. OUTLINE Power is supplied at all times through 15 fuse (No. 43, located in the IPDM E/R) to front fog lamp relay, located in the IPDM E/R, and through 50 fusible link (letter f, located in the fuse and fusible link box) to CM terminal 70. When the ignition switch is in ON or STRT position, power is supplied through 10 fuse [No. 1, located in the fuse block (J/)] to CM terminal 38. When the ignition switch is in CC or ON position, power is supplied through 10 fuse [No. 6, located in the fuse block (J/)] to CM terminal 11. Ground is supplied to CM terminal 67 through grounds F14, M57 and M61. J LT L M LT-59

60 FRONT FOG LMP FOG LMP OPERTION The fog lamp switch is built into the combination switch. The lighting switch can only be in UTO position (with auto light system) or headlamps 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 of the IPDM E/R grounds the coil side of the fog lamp relay. The fog lamp relay then directs power through IPDM E/R terminal 37 to front fog lamp LH terminal 1, and through IPDM E/R terminal 36 to front fog lamp RH terminal 1. Ground is supplied to front fog lamp LH terminal 2 through grounds E15 and E24, and to front fog lamp RH terminal 2 through grounds E15 and E24. With power and grounds supplied, the front fog lamps illuminate. TTERY SVER CONTROL When the fog lamp switch is ON and the ignition switch is turned from ON to CC or OFF, or if the ignition switch is in the OFF position when the fog lamp switch is turned ON, the battery saver control feature is activated. Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, unless the combination switch (lighting switch) position is changed. If the combination switch (lighting switch) position is changed, then the fog lamps (and headlamps) are turned off. CN Communication System Description Refer to LN-20, "CN COMMUNICTION".

When the lighting switch is placed in the 1ST position, the CM (body control module) receives input signal requesting the parking, license plate, and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the parking, license plate, and tail lamps, which then illuminate. Power is supplied at all times through 10 fuse (No. 41, located in the IPDM E/R) to tail lamp relay, located in the IPDM E/R, and through 50 fusible link (letter f, located in the fuse and fusible link box) to CM terminal 70. With the ignition switch in the ON or STRT position, power is supplied through 10 fuse [No. 1, located in the fuse block (J/)] to CM terminal 38. With the ignition switch in the CC or ON position, power is supplied through 10 fuse [No. 6, located in the fuse block (J/)] to CM terminal 11.
