Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003860432
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” of 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 must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

 Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body)
 Replace magnetic switch if continuity does not exist.
2. Continuity test (between “S” terminal and “M” terminal)
 Replace magnetic switch if continuity does not exist.
PINION PROTRUSION LENGTH
 Compare movement “L” in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
 If the measurement value is not in the specified area, adjust with
the adjusting plate.

1. Inspect pinion teeth.
 Replace pinion if teeth are worn or damaged. (Also check con-
dition of ring gear teeth.)
2. Inspect reduction gear teeth.
 Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.
 Replace pinion assembly if it is locked or rotated in both direc-
tions or unusual resistance is evident.
BRUSH HOLDER ASSEMBLY
Brush
 Check wear of brush.
 Replace brush if the measurement value is less than the specified
value.
Brush Spring
 Check brush spring tension with brush spring detached from
brush.
 Replace brush spring if the measurement value is less than the
specified value.
Brush Holder
1. Perform insulation test between brush holder (positive side) and
its base (negative side).
- Replace brush holder assembly if continuity does not exist.
2. Check brush to see if it moves smoothly.
- If brush holder is bent, replace it if sliding surface is dirty, clean.

Magnet is secured to yoke by bonding agent. Check magnet to see
that it is secured to yoke and for any cracks. Replace malfunctioning
parts as an assembly.
CAUTION:
Never clamp yoke in a vise or strike it with a hammer.
ARMATURE CHECK
1. Continuity test (between two segments side by side)
- Replace if continuity does not exist.
2. Insulation test (between each commutator bar and shaft)
- Replace if continuity exists.
3. Check commutator surface.
- Grind commutator with No. 500 – 600 emery paper if the surface
is rough.
4. Check diameter of commutator.
- Replace armature assembly if the measurement value is less
than the specified value.
