11. Check hydraulic lashadjusters.
a. Push rocker armathydraulic lashadjuster location, andsee
if rocker armmoves. Ifitmoves atleast 1mm (0.04 in),it
indicates thatthere isair inthe high pressure chamber.
Noise willbeemitted fromhydraulic lashadjuster ifengine
is started without bleeding air.
b. Remove hydraulic lashadjuster anddipinacontainer filled
with engine oil.While pushing plungerasshown infigure,
lightly pushcheck ballusing athin rod. Airiscompletely
bled when plunger nolonger moves.

Air cannot bebled from thistype oflash adjuster byrunning the

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.
