Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of 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-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 inflation, all maintenance should be per-
formed 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 tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions
+Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
+Disassembly should be done in a clean work area.
+Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
+Place disassembled parts in order for easier and proper assembly.
+All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection
or reassembly.
+Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
+It is very important to perform functional tests whenever they are indicated.
+The valve body contains precision parts and requires extreme care when parts are removed and ser-
viced. Place removed parts in a parts rack in order to replace them in correct positions and sequences.
Care will also prevent springs and small parts from becoming scattered or lost.
+Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
+Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, and to hold bearings and washers in place during assembly. Do not use grease.

DESCRIPTION
The revolution sensor detects the revolution of the out put shaft
parking pawl lock gear and emits a pulse signal. The pulse sig-
nal is sent to the TCM which converts it into vehicle speed.
