Super multiple junction (SMJ)

In wiring diagram, connectors consistingofterminals havingterminal numbers withanalphabet (81,
DO, etc.) areSMJ connectors.
If connector numbersareshown inReference Area,these connector symbolsarenotshown inConnec-
tor Area. Forterminal arrangement ofthese connectors, refertothe foldout pageatthe end ofthis
manual.

Joint connector

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.

Incident Simulation Tests(Cont'd)
Engine compartment

There areseveral reasons avehicle orengine vibration could•
cause anelectrical complaint. Someofthe things tocheck for
are:
• Connectors notfully seated.
• Wiring harness notlong enough andisbeing stressed due
to engine vibrations orrocking.
• Wires laying across brackets ormoving components.
• Loose, dirtyorcorroded groundwires.
• Wires routed tooclose tohot components.
To inspect components underthehood, startbyverifying the
integrity ofground connections. (RefertoGROUND INSPEC-
TION described later.)Firstcheck thatthesystem isproperly
grounded. Thencheck forloose connection by
gently shaking

the wiring orcomponents aspreviously explained. Usingthe
wiring diagrams inspectthewiring forcontinuity.

Behind theinstrument panel

An improperly routedorimproperly clampedharnesscan
become pinchedduringaccessory installation. Vehiclevibra-
tion canaggravate aharness whichisrouted alongabracket
or near ascrew.

Under seating areas

An unclamped orloose harness cancause wiring tobe pinched
by seat components (suchasslide guides) duringvehicle vibra-
tion. Ifthe wiring runsunder seating areas,inspect wirerout-
ing forpossible damageorpinching.

Heating test

Do not heat above 60°C(140°F).

8GI842 HEAT
SENSITIVE

The owner's problem mayoccur during hotweather orafter car
has satforashort time.Insuch cases youwillwant tocheck
for aheat sensitive condition.
To determine ifan electrical component isheat sensitive, heat
the component withaheat gunorequivalent.

Do not heat components above
60°C
(140°F).
Ifincident occurs
while heating theunit, either replace orproperly insulatethe
component.
