The camshaft positionsensorisabasic component ofthe

input signals tothe ECM areused tocontrol fuelinjection, igni-

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.

The maintenance itemslistedhereshould beperformed fromtimetotime, unless oth-
erwise specified.

Tires
Check thepressure withagauge periodically whenataservice station, including
the spare, andadjust tothe specified pressureifnecessary. Checkcarefully fordamage,
cuts orexcessive wear.

Windshield wiperblades

Doors andengine hood
Check thatalldoors, theengine hood,thetrunk lidand back
door operate properly. Alsoensure thatalllatches locksecurely. Lubricate hinges,
latches, rollersandlinks ifnecessary. Makesurethatthesecondary latchkeeps thehood
from opening whentheprimary latchisreleased.
When driving inareas usingroadsaltorother corrosive materials, checkforlubrication
frequently.

Tire rotation
Tiresshould berotated every

performing periodicmaintenance, cleaningthevehicle, etc.

Lights
Makesurethattheheadlights, stoplights, taillights, turnsignal lights,andother
lights arealloperating properlyandinstalled securely. Alsocheck headlight aim.

Warning lightsandbuzzers/chimes
Makesurethatallwarning lightsandbuzzers/chimes
are operating properly.

Steering wheel
Check forchange inthe steering conditions, suchasexcessive freeplay,
hard steering orstrange noises.

Free play: Lessthan35mm (1.38 in)
Seat belts
Check thatallparts ofthe seat beltsystem (e.g.buckles, anchors, adjusters
and retractors) operateproperly andsmoothly, andareinstalled securely. Checkthebelt
webbing forcuts, fraying, wearordamage.

UNDER THEHOOD ANDVEHICLE

The maintenance itemslisted hereshould bechecked periodically e.g.each timeyou
check theengine oilorrefuel.

Windshield washerfluid
Check thatthere isadequate fluidinthe tank.

Engine coolant level
Check thecoolant levelwhen theengine iscold.

Engine oillevel
Check thelevel afterparking thevehicle onalevel spotandturning off
the engine.

Brake andclutch fluidlevels
Makesurethatthebrake andclutch fluidlevels arebetween
the "MAX" and"MIN" linesonthe reservoir.

Battery
Checkthefluid level ineach cell.Itshould bebetween the"MAX" and"MIN"
lines.
