BRUSH CHECKNJSC0022S021. Check smooth movement of brush.
Not smooth ... Check brush holder and clean.
2. Check brush for wear.
Replace brush if it is worn down to the limit line.
SEL037Z
STATOR CHECKNJSC0022S031. Continuity test
No continuity ... Replace stator.
2. Ground test
Continuity exists ... Replace stator.

Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
NJST0044The 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 for certain types of
collision. The SRS system composition which is available to NISSAN MODEL N16 is as follows (The compo-
sition 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 steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front 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), side air bag (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 removalofSpiralCableandAir
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. SRS wiring harnesses (except “SEAT BELT PRE-TENSIONER” connector) can be
identified by yellow harness connector.
Precautions for Steering SystemNJST0003Before disassembly, thoroughly clean the outside of the unit.
Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
Place disassembled parts in order, on a parts rack, for easier and proper assembly.
Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
Before inspection or reassembly, carefully clean all parts with a generalpurpose, non-flammable
solvent.
Before assembly, apply a coat of recommended power steering fluid* to hydraulic parts. Vaseline
may be applied to O-rings and seals. Do not use any grease.
Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals andgaskets during instal-
lation. Perform functional tests whenever designated.
