Precautions for Supplemental Restraint System
(SRS) “AIR BAG” and “SEAT BELT
PRE-TENSIONER”

NLEC1745

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 air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor 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 helps to reduce the risk or severity of injury to the driver and front passenger in a side col-
lision. 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 the RS section 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 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 can be identified with yellow harness connector (and with
yellow harness protector or yellow insulation tape before the harness connectors).

Precautions for On Board Diagnostic (OBD)
System of Engine and CVT

NLEC1332

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver
of a malfunction causing emission deterioration.

CAUTION:

Be sure to turn the ignition switch “OFF” and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc.
will cause the MI to light up.

Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

Certain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector.
For description and how to disconnect, refer to EL section, “Description”, “HARNESS CONNEC-
TOR”.

Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MI to light up due to the short circuit.

Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of fuel injection system, etc.

Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and
TCM (Transmission Control Module) before returning the vehicle to the customer.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”

EC-555

SEF706Y

Engine Fuel & Emission Control System

=NLEC1333

Always use a 12 volt battery as power source.

Do not attempt to disconnect battery cables while engine
is running.

Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the
ECM because battery voltage is applied to ECM even if
ignition switch is turned off.

SEF707Y

Do not disassemble ECM.

If a battery terminal is disconnected, the memory will
return to the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is
disconnected. However, this is not an indication of a prob-
lem. Do not replace parts because of a slight variation.

SEF908W

When

ECM

harness

connector, use lever as shown.
When connecting, fasten connector securely with lever
moved until it stops.

SEF291H

When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminals when connecting pin connectors.

Securely connect ECM harness connectors.
A Poor connection can cause an extremely high (surge)
voltage to develop in coil and condenser, thus resulting in
damage to ICs.

Keep ECM harness at least 10 cm (4 in) away from adja-
cent harness, to prevent an ECM system malfunctions due
to receiving external noise, degraded operation of ICs, etc.

Keep ECM parts and harness dry.

PRECAUTIONS

SR20DE

Engine Fuel & Emission Control System

EC-556

MEF040D

Handle mass air flow sensor carefully to avoid damage.

Do not disassemble mass air flow sensor.

Do not clean mass air flow sensor with any type of deter-
gent.

Do not disassemble IAC valve-AAC valve.

Even a slight leak in the air intake system can cause seri-
ous problems.

Do not shock or jar the camshaft position sensor and
crankshaft position sensor.

Before replacing ECM, perform refer to “ECM Terminals
and Reference Value” inspection and make sure ECM
functions properly, EC-657.

SAT652J

After performing each TROUBLE DIAGNOSIS, perform
“DTC Confirmation Procedure” or “Overall Function
Check”.
The DTC should not be displayed in the “DTC Confirma-
tion Procedure” if the repair is completed. The “Overall
Function Check” should be a good result if the repair is
completed.

SEF348N

When measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.

Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM’s transistor. Use a ground other than ECM terminals,
such as the ground.

PRECAUTIONS

Engine Fuel & Emission Control System (Cont’d)

EC-557

SEF605X

Do not operate fuel pump when there is no fuel in lines.

Tighten fuel hose clamps to the specified torque.

SEF709Y

Do not depress accelerator pedal when starting.

Immediately after starting, do not rev up engine unneces-
sarily.

Do not rev up engine just prior to shutdown.

SEF708Y

When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.

1) Keep the antenna as far as possible from the electronic

control units.

2) Keep the antenna feeder line more than 20 cm (8 in) away

from the harness of electronic controls.
Do not let them run parallel for a long distance.

3) Adjust the antenna and feeder line so that the standing-

wave ratio can be kept smaller.

4) Be sure to ground the radio to vehicle body.

Wiring Diagrams and Trouble Diagnosis

NLEC1334

When you read Wiring diagrams, refer to the following:

GI-11, “HOW TO READ WIRING DIAGRAMS”

EL-10, “POWER SUPPLY ROUTING” for power distribution cir-
cuit

When you perform trouble diagnosis, refer to the following:

GI-32, “HOW TO FOLLOW TEST GROUPS IN TROUBLE
DIAGNOSES”
