LT-4 < SERVICE INFORMATION > PRECAUTIONS SERVICE INFORMATION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000001612924 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. 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 “SUPPLEMENTAL RESTRAINT SYS- TEM” and “SEAT BELTS” of this Service Manual. WARNING: • 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 NISSAN/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 Air Bag Module, see the “SUPPLEMENTAL RESTRAINT SYSTEM”. • 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 Precaution for Service Operation INFOID:0000000001328264 • Never work with wet hands. • 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). • 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. • 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 dis- charge 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 perfor- mance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when replac- ing the bulb. • 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.

HEADLAMP - XENON TYPE - LT-5 < SERVICE INFORMATION > C D E F G H I J L M A B LT N O P HEADLAMP - XENON TYPE - Component Parts and Harness Connector Location INFOID:0000000001328265 System Description INFOID:0000000001328266 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/ R (intelligent power distribution module engine room) through the CAN communication lines. The CPU (central processing unit) located in the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays, when energized, direct power to the respective headlamps, which 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. OUTLINE Power is supplied at all times • to headlamp high relay, located in IPDM E/R • to headlamp low relay, located in IPDM E/R and • to ignition relay, located in IPDM E/R, from battery direct, • through 10A fuse (No. 71, located in IPDM E/R) • to CPU located in IPDM E/R, • through 15A fuse (No. 78, located in IPDM E/R) • to CPU located in IPDM E/R, • through 50A fusible link (letter M, located in fuse, fusible link and relay box) • to BCM terminal 55, • through 15A fuse [No. 22, located in fuse block (J/B)] • to BCM terminal 42, • through 10A fuse [No. 19, located in fuse block (J/B)] • to combination meter terminal 8. With ignition switch in ON or START position, power is supplied • to ignition relay, located in IPDM E/R, from battery direct • through 15A fuse [No. 1, located in fuse block (J/B)] • to BCM terminal 38, • through 10A fuse [No. 14, located in fuse block (J/B)] PKIC9683E Revision: 2007 April 2008 FX35/FX45
