PRECAUTIONS

Supplemental Restraint System (SRS) “AIR BAG”
Supplemental Restraint System (SRS) “AIR BAG”
The Supplemental Restraint System “AIR BAG”, used alongwith a seat belt, helps to reduce therisk or severity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and on the instrument panel on the passen­ger side), a diagnosis sensor unit, warning lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
쐌 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 should be per­formed by an authorized NISSAN dealer.
쐌 Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
쐌 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the harness connectors or for the complete harness, for easy identification.

Flash to Pass Operation
When the combination switch is placed in the FLASH TO PASS (C) position, ground is supplied
쐌 to headlamp control unit terminal 20 쐌 through combination switch terminal 13 쐌 to combination switch terminal 12 쐌 through body grounds E3, E30 and E50.
Then, power is supplied to each headlamp (HIGH) from headlamp control unit to turn on the lamps in the same manner as high beam operation.
AUTO LAMP OPERATION (IF EQUIPPED) Automatic Illumination
When the ignition switch is in ON position, power is supplied
쐌 through 10A fuse (No. 30, located in the fuse block) 쐌 to headlamp control unit terminal 2.
With power at terminal 2 and lighting switch in AUTO1 or AUTO2 position, the headlamp control unit will mea­sure the ambient light intensity through terminals 10 and 21. If the autolamp sensor does not detect sufficient light, power is supplied to headlamps in the same manner as low or high beam operation. Headlamp control unit decides to illuminate headlamps (Low or High) according to combination switch position (LOW or HIGH). At this time, ground is also supplied to tail lamp relay through headlamp control unit terminal 12 to energize tail lamp relay. Then tail lamp relay supplies power to turn on parking, license, tail lamps and illumination. For detailed wiring diagrams, refer to “PARKING, LICENSE, TAIL LAMPS”, EL-53 and “ILLUMINATION”, EL-68.
Shut-off Delay
While the headlamps are lit in the automatic illumination mode, the ignition switch is turned from ON to OFF position and auto lamp shut-off delay timer starts. At this time, ground to tail lamp relay is discontinued. The delay time is set based on the resistance value at headlamp control unit terminal 14. With the timer running, the headlamps remain lit. When the timer reaches the end of its cycle, the headlamps turn off. Headlamp lighting time can be adjusted from 0 to 3 minutes.

When the ignition switch is in ON position, power is supplied
쐌 through 10A fuse (No. 30, located in the fuse block) 쐌 to headlamp control unit terminal 2.
With power at terminal 2 and lighting switch in AUTO1 or AUTO2 position, the headlamp control unit will mea­sure the ambient light intensity through terminals 10 and 21. If the autolamp sensor does not detect sufficient light, power is supplied to headlamps in the same manner as low or high beam operation. The headlamp con­trol unit illuminates the headlamps High or Low according to combination switch position HIGH or LOW. At this time, ground is also supplied to tail lamp relay through headlamp control unit terminal 12 to energize tail lamp relay. Then tail lamp relay supplies power to turn on parking, license, tail lamps and interior illumi­nation. (For detailed wiring diagrams, refer to “PARKING, LICENSE, TAIL LAMPS, EL-53 and “ILLUMINATION”, EL-68.)
Shut-off Delay
NDEL0020S0302
While the headlamps are lit in the automatic illumination mode and the ignition switch is turned from ON to OFF position, the autolamp shut-off delay timer starts. At this time, ground to tail lamp relay is discontinued. The delay time is set based on the resistance value at headlamp control unit terminal 14. With the timer running, the headlamps remain lit. When the timer reaches the end of its cycle, the headlamps turn off. Headlamp lighting time can be adjusted from about 0 to 3 minutes.
THEFT WARNING SYSTEM
NDEL0020S04
If the theft warning system is triggered, alarm signal is sent
쐌 to headlamp control unit terminal 19 쐌 from smart entrance control unit terminal 29.
