‘Supplemental Restraint System (SRS) “AIR
BAG"

1 System “Air Bag", used along with a seat bol helps 10 reduce the risk or sever
ry 16 the 00001 in afrentalcolision. The Supplemental Restraint Systom cons ls of an air bag mod-
le (located in the center rihe sieering wee), a diagnosis sensor uni warning lamp, wiring harness, crash
zone sensor (AWD models) and sprl cable. Information necessary to service the system salely ¡included
inthe RS section of is Service Manual
WARNING:

+ To avoid rendering the SAS inoperative, which could increase the risk of personal injury or death
in the event of colision 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 clrcu related to the SAS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
hamess connactors or for the complete harness, for easy identification.

Precautions for On Board Diagnostic (OBD)
‘System of Engine

The ECM (ECOS control module) has an on-board diagnostic system. 1101 lght up the malfunction indica

・ Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the ML to light up due tothe open circuit (Be sure Ihe connector is free from water, grease,
dir, bent terminals, et.)

・ Be sure to route and secure the hamesses properly after work. The Interference of the hamess with
A bracket, ote. may cause the MIL to light up due fo the short circu

・ Be sure to connect rubber lubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL 10 light up due 10 the malfunction of the EGR system or fuel Injection system,

・ Be aure to erase the unnecessary malfunction information (repairs completed) from tho ECM before
returning the vehicle tothe customer,

‚nd disconnect the negative battery terminal before any
ult of related switches, sensors, solenoid valves, etc.

PRECAUTIONS AND PREPARATION

Precautions

・ Before connecting or disconnecting the ECM harnoss
connector, tum ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the
ECM because battery voltage ls applied to ECM even it
Ignition switch is turned oft.

・ When connecting ECM harness connector, tighten secur
ing bolt until the gap between orange Indicators disap-
pears.

8: 3-5 Nm (0.3 - 0.5 kgm, 26- 43 in-b)

・ Wnen connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).

Make sure that there aro not any bends or breaks on ECM
pin terminal, when connecting pin connectors.

・ Before replacing ECM, pertorm ECM Terminals and Reter-
tence Value inspection and make sure ECM functions prop"
erly, Refer to EG-85,

・ After performing each TROUBLE DIAGNOSIS, pertorm

"OVERALL FUNCTION CHECK” or "DTC (Diagnostic
‘Trouble Code) CONFIRMATION PROCEDURE”.
‘The DTC should not be displayed in the “DTC CONFIRMA-
TION PROCEDURE” it the repair Is completed. The
“OVERALL FUNCTION CHECK" should be » good result if
the repair is completed.

PRECAUTIONS AND PREPARATION
Precautions (Contd)

When mensuring ECM signals with a circuit tester, never

allow the two tester probes to contact.

‘Accidental contact of probes will cause a short circuit

damage the ECM power transistor.

TROUBLE DIAGNOSIS — Introduction

Introduction

Tre engine has an ECM to control major systems such as fuel

accepts put signals Wry sansors and nstanty 00406 actuators,
IU ls essential at both input and cuipul signals are proper and
stable. A Ihe samo time, itis important that Ihere are no problems.
such as vacuum leaks, fouled spark plugs, or other problems wih
the engine.

itis much more dificult to ciagnose a problem that occurs inter
terty rather than continuously. Most intermittent problems are
caused by poor 00006 connections or Improper wifing In 006
‘case, careful checking of suspected circus may halo prevent the
replacoment of good pant.

A visual check ony may nol ind the cause ofthe problems, Area
test with CONSULT (or GST) or a 00601 tester connected 하 000
be performed. Follow tho "Work Flow” on the noxt page,

Before undertaking actual chocks, lake à few minutes 10 talk wth
a customer who approaches wit a crvoabily complain. Tha cus-
amer can supply good information about such problems, espe:
Galy hemmilent ones. Find out wal symploms are present and
under what condtions they occur. À "Diagnostic Worksheet” Ike
the example on the next vage should be used.
