SWITCH POSITIONS
Switches areshown inwiring diagrams asifthe vehicle isin
the "normal" condition.
A vehicle isin the "normal" conditionwhen:
• ignition switchis"OFF",
• doors, hoodandtrunk lid/back doorareclosed,
• pedals arenotdepressed, and
• parking brakeisreleased.
Normally closed
5GI860DETECTABLE LINESANDNON-DETECTABLE LINES
In some wiring diagrams, twokinds oflines, representing
wires, withdifferent weightareused.
• Aline with regular weight(widerline)represents a"detect-
able lineforDTC (Diagnostic TroubleCode)".A"detectable
line forDTC" isacircuit inwhich ECM(ECCS control mod-
ule) candetect itsmalfunctions withtheon-board diagnos-
tic system.
• Aline with lessweight (thinner line)represents a"non-de-
tectable lineforDTC", A"non-detectable lineforDTC" isa
circuit inwhich ECMcannot detectitsmalfunctions withthe
on-board diagnostic system.

HOWTOPERFORM EFFICIENT DIAGNOSIS FORANELECTRICAL INCIDENT
Incident Simulation Tests
INTRODUCTION
Sometimes thesymptom isnot present whenthevehicle isbrought infor service.
If
possible, re-create
the conditions presentatthe time ofthe incident. Doingsomay help avoid aNo Trouble FoundDiag-
nosis. Thefollowing sectionillustrates waystosimulate theconditionslenvironment underwhich the
owner experiences anelectrical incident.
The section isbroken intothesixfollowing topics:
• Vehicle vibration
• Heat sensitive
• Freezing
• Water intrusion
• Electrical load
• Cold orhot start up
Get athorough description ofthe incident fromthecustomer. Itis important forsimulating thecondi-
tions ofthe problem.
VEHICLE VIBRATION
The problem mayoccur orbecome worsewhiledriving onarough roadorwhen engine isvibrating
(idle with
AIC
on). Insuch acase, youwillwant tocheck foravibration relatedcondition. Refertothe
illustration below.
Connectors
&
harness
Determine whichconnectors andwiring harness wouldaffecttheelectrical systemyouareinspecting.
Gently
shakeeachconnector andharness whilemonitoring thesystem forthe incident youaretrying
to duplicate. Thistestmay indicate aloose orpoor electrical connection.
Hint
Connectors canbeexposed tomoisture. Itis possible toget athin film ofcorrosion onthe connector
terminals. Avisual inspection maynotreveal thiswithout disconnecting theconnector. Ifthe problem
occurs intermittently, perhapstheproblem iscaused bycorrosion. Itis agood ideatodisconnect, inspect
and clean theterminals onrelated connectors inthe system.
Sensors
&
relays
Gently
applyaslight vibration tosensors andrelays inthe system youareinspecting.
This testmay indicate aloose orpoorly mounted sensororrelay.

HOWTOFOLLOW FLOWCHART INTROUBLE DIAGNOSES
NOTICE
The flow chart indicates workprocedures requiredtodiagnose
problems effectively. Observethefollowing instructions before
diagnosing.
1) Use theflow chart afterlocating probable causesofaprob-
lem following the"Preliminary Check",the"Symptom
Chart" orthe "Work Flow".
2) After repairs, re-check thattheproblem hasbeen com-
pletely eliminated.
3) Refer toComponent PartsandHarness Connector Location
for the Systems described ineach section foridentificationl
location ofcomponents andharness connectors.
4) Refer tothe Circuit Diagram forQuick Pinpoint Check.
If you must check circuit continuity betweenharnesscon-
nectors inmore detail, suchaswhen asub-harness isused,
refer toWiring Diagram ineach individual sectionandHar-
ness Layout inEL section foridentification ofharness con-
nectors.
5) When checking circuitcontinuity, ignitionswitchshould be
"OFF" .
6) Before checking voltageatconnectors, checkbattery volt-
age.
7) After accomplishing theDiagnostic Procedures andElectri-
cal Components Inspection,makesurethatallharness con-
nectors arereconnected asthey were.

PRECAUTIONSANDPREPARATION
Supplemental RestraintSystem(SRS)"AIR
BAG" (DualAirBag System)
The Supplemental RestraintSystem"AirBag" usedalong withaseat belt,helps toreduce therisk or
severity ofinjury tothe driver andfront passenger inafrontal collision. TheSupplemental Restraint
System consists ofair bag modules (locatedinthe center ofthe steering wheelandonthe instrument
panel onthe passenger side),adiagnosis sensorunit,warning lamp,wiring harness andspiral cable.
Information necessarytoservice thesystem safelyisincluded inthe
RSsection
ofthis Service Manual.
WARNING:
• Toavoid rendering theSRS inoperative, whichcouldincrease therisk ofpersonal injuryordeath
in the event ofacollision whichwould resultinair bag inflation, allmaintenance mustbeperformed
by an authorized NISSANdealer.
• Improper maintenance, includingincorrectremovalandinstallation ofthe SRS, canlead topersonal
injury caused byunintentional activationofthe system.
• Donot use electrical testequipment onany circuit related tothe SRS unless instructed tointhis
Service Manual. SRSwiring harnesses arecovered withyellow insulation eitherjustbefore the
harness connectors orfor the complete harness,foreasy identification.
