System Description
FUNCTION
Multi-remote control system has the following function.
lDoor lock
lDoor unlock
lHazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder.)
lAll door switches CLOSED
When the LOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
lthrough multi-remote control unit terminalV10
lto smart entrance control unit terminalV4and
lto door lock relay terminalV6.
Then smart entrance control unit operates to lock doors (except for driver's door) and door lock relay ener-
gized to lock driver's door.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder)
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
lthrough multi-remote control unit terminalV11
lto smart entrance control unit terminalV5and
lto door lock relay terminalV5.
Then smart entrance control unit operates to unlock doors (except for driver's door) and door lock relay is
energized to unlock driver's door.
HAZARD REMINDER
When the doors and locked or unlocked by multi-remote controller, ground is supplied
lto terminalV1of multi-remote control relay-1 and 2
lthrough multi-remote control unit terminalV12.
Then the relays are energized and hazard warning lamp flashes as follows
lLock operation: Flash once
lUnlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will erase
all ID codes previously entered. Therefore, be sure to receive all remote controllers from the vehicle owner
when any ID code entry is performed.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
lDriver side LOCKED signal (from driver side door unlock sensor)
lDoor switch CLOSED signal
lKey switch signal (INSERTED/WITHDRAWN)
lAccessory power supply
lSignal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-2139.

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal
collision. The SRS system composition which is available to NISSAN MODEL D22 is as follows (The com-
position varies according to the destination and optional equipment.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
lTo 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 dealer.
lImproper 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 RS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral Cable and wiring harnesses (except ``SEAT BELT PRE-TENSIONER'')
covered with yellow insulation either just before the harness connectors or for the complete har-
ness are related to the SRS.
