PRECAUTIONS LT-3 < SERVICE INFORMATION > C D E F G H I J L M A B LT N O P SERVICE INFORMATION PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000004409087 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 SRS and SB section of this Service Man- ual. 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 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.

LT-4 < SERVICE INFORMATION > HEADLAMP (FOR USA) HEADLAMP (FOR USA) Component Parts and Harness Connector Location INFOID:0000000004409088 System Description INFOID:0000000004409089 Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input signal requesting the headlamps (and tail lamps) illuminate. The BCM sends a signal, via the CAN communication lines, to the IPDM E/R (intelligent power distribution module engine room) requesting the headlamps be turned ON. The CPU (central processing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils. These relays direct power to the respective headlamps, which then illuminate. OUTLINE Power is supplied at all times • to headlamp high relay RH and LH (located in IPDM E/R), • to headlamp low relay (located in IPDM E/R), • to ignition relay (located in IPDM E/R), • through 15A fuse (No. 52, located in IPDM E/R) and • through 20A fuse (No. 53, located in IPDM E/R) • to CPU located in IPDM E/R, • through 50A fusible link (letter j, located in fuse and fusible link block) • to BCM terminal 70, • through 10A fuse [No. 21, located in fuse block (J/B)] • to BCM terminal 57, and • through 10A fuse [No. 19, located in fuse block (J/B)] • to combination meter terminal 1. With the ignition switch in the ON or START position, power is supplied • to the ignition relay (located in IPDM E/R), • through 10A fuse [No. 12, located in fuse block (J/B)] • to BCM terminal 38, • through 10A fuse [No. 14, located in fuse block (J/B)] • to combination meter terminal 2. With the ignition switch in the ACC or ON position, power is supplied • through 10A fuse [No. 6, located in fuse block (J/B)] • to BCM terminal 11. Ground is supplied • to BCM terminal 67 • to combination meter terminals 3 and 21 • through grounds M57 and M61, and • to IPDM E/R terminals 39 and 59 • through grounds E9, E15 (all models) and E24 (with MR20DE). HEADLAMP OPERATION Low Beam Operation 1. IPDM E/R E46, E47 and E48 2. BCM M18 and M20 (view with instru- ment panel removed) 3. Combination switch (lighting switch) M28 4. Combination meter M24 WKIA5751E

HEADLAMP (FOR USA) LT-5 < SERVICE INFORMATION > C D E F G H I J L M A B LT N O P With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illuminate. The BCM then sends a signal, via the CAN communication lines, to the IPDM E/R requesting the low beam headlamps be turned ON. The CPU located in the IPDM E/R controls ground to the headlamp low relay coil, which when energized, directs power • through 15A fuse (No. 41, located in IPDM E/R) • through IPDM E/R terminal 54 • to headlamp RH terminal 3, and • through 15A fuse (No. 40, located in IPDM E/R) • through IPDM E/R terminal 52 • to headlamp LH terminal 3. Ground is supplied • to headlamp RH and LH terminals 5 • through grounds E9, E15 (all models) and E24 (with MR20DE). With power and ground supplied, low beam headlamps illuminate. High Beam Operation/Flash-to-Pass Operation With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives an input signal requesting the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a signal to the BCM. This input signal is then communicated to the IPDM E/R and the combination meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relays (LH and RH), which when energized, directs power • through 10A fuse (No. 34, located in IPDM E/R) • through IPDM E/R terminal 56 • to headlamp RH terminal 6, and • through 10A fuse (No. 35, located in IPDM E/R) • through IPDM E/R terminal 55 • to headlamp LH terminal 6. Ground is supplied • to headlamp RH and LH terminal 5 • through grounds E9, E15 (all models) and E24 (with MR20DE). With power and ground supplied, the high beam headlamps illuminate. The BCM sends a signal, via the CAN communication lines, to the combination meter requesting the high beam indicator lamp be turned ON.
