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 Y61 is as follows (The composition var-
ies according to the destination.):
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:
+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 in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper 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.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
PRECAUTIONS

Description
HARNESS CONNECTOR
+All harness connectors have been modi®ed to prevent accidental looseness or disconnection.
+The connector can be disconnected by pushing or lifting the locking section.
CAUTION:
Do not pull the harness when disconnecting the connector.

System Description
CIRCUIT OPERATION
[Example]
Aiming switch ``0''
+When the aiming switch is set to ``0'', the motor will not start.
This is because the power terminals are positioned at the non-
conductive section of the sensor's rotary unit.
Aiming switch ``0''®``1''
+When the aiming switch is moved from ``0'' to ``1'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The headlamps will then move
in the ``DOWN'' direction.
+The motor continues to rotate while the rotary unit of the sen-
sor moves from point A to point B.
+The power terminals will then be positioned at the nonconduc-
tive section, disconnecting the power to the motor. The motor
will then stop.
Aiming switch ``1''®``0''
+When the aiming switch is moved from ``1'' to ``0'', the sensor's
conductive section activates the relay. Power is supplied
through the relay to the motor. The motor will rotate to move the
headlamps in the ``UP'' direction.
+When the rotary unit of the sensor moves from point B to point
A, the motor will stop.

System Description
Front interior room lamp timer is controlled by smart entrance control unit while interior room lamp switch is
in the ``DOOR'' position.
Smart entrance control unit does not control rear interior room lamp.
TIMER OPERATION
Interior room lamp timer keeps interior room lamp illuminated for about 15 seconds when:
+driver's door is unlocked while key is out of ignition key cylinder,
+key is withdrawn from ignition key cylinder while driver's door is closed, and
+driver's door is opened and then closed while ignition switch is not in the ``ON'' position.
The timer is cancelled, and interior room lamp turns off when:
+driver's door is locked, or
+ignition switch is turned ``ON''.
ON-OFF CONTROL
When the front driver side door, front passenger side door, rear LH door, rear RH door or back door is opened,
interior room lamp turns on.
When driver side door is opened and then closed while ignition switch is not in the ON position, interior room
lamp timer operates. (Timer does not operate when doors other than the driver side door is opened and
closed.)
