Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)“AIR
BAG”and“SEAT BELT PRE-TENSIONER”
The Supplemental Restraint System “Air Bag” and “Seat Belt Pre-tensioner”, used along with a seat belt,
help to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The
Supplemental Restraint System consists of an air bag module (located in the center of the steering wheel
and on the instrument panel on the passenger side, where fitted), seat belt pre-tensioners, a diagnosis sen-
sor unit, warning lamp, wiring harness and spiral cable.
In addition to the supplemental air bag modules for a frontal collision, the supplemental side air bag used
along with the seat belt help to reduce the risk or severity of injury to the driver and front passenger in a
side collision. The supplemental side air bag consists of air bag modules (located in the outer side of front
seats), satellite sensor, diagnosis sensor unit (one of components of supplemental air bags for a frontal
collision), wiring harness, warning lamp (one of components of supplemental 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 must 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.

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-TENSIONER”connector) can be
identified with yellow harness connector (and with yellow harness protector or yellow insulation
tape before the harness connectors). Not use electrical test equipment on any circuit related to
the SRS.
PRECAUTIONS AND PREPARATION
EL-5

Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and
suitable test probes are necessary for the test. The alternator can be checked easily by referring to the
Inspection Table.

Before starting, inspect the fusible link.

Use fully charged battery.

Note:

If the inspection result is OK even though the charging system is malfunctioning, check the B
terminal connection. (Check the tightening torque.)

When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary,
replace faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate“CHARGE”warning lamp, if any of the following
symptoms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Removal and Installation
1. Loosen lock bolt.
2. Remove RH undertray.
3. Loosen alternator mounting bolt and remove drive belt.
4. Remove lock bolt and adjust.
5. Remove harness connectors.
6. Remove alternator mounting bolt.
7. Support engine with jack, and remove front engine mounting
bolt.
8. Remove alternator.
Disassembly
REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used
to lock outer race of rear bearing. To facilitate removal of
rear cover, heat bearing box section with a 200W soldering
iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARING
CAUTION:

Do not reuse rear bearing after removal. Replace with a
new one.

Do not lubricate rear bearing outer race.
Inspection
ROTOR CHECK
1. Resistance test
Resistance: Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.
2. Insulator test

Continuity exists ... Replace rotor.
3. Check slip ring for wear.
Slip ring minimum outer diameter:
Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.
