BATTERY • Always usea12 volt battery aspower
source.
• Do not attempt todisconnect battery
cables whileengine isrunning.
INJECTOR • Do not disconnect injectorharness
connectors withengine running.
• Do not apply battery powerdirectly to
injectors.
ECCS PARTS HANDLING
• Handle massairflow sensor carefully to
avoid damage.
• Do not disassemble massairflow
sensor.
• Do not clean massairflow sensor with
any type ofdetergent.
• Do not disassemble IACV-AACvalve.
• Even aslight leakinthe airintake
system cancause serious problems.
• Do not shock orjar the camshaft
position sensor. ECM
• Do not disassembly EGM(EGGS control
module).
• Do not turn diagnosis modeselector
forcibly.
• Ifabattery terminal isdisconnected,
the memory willreturn tothe ECM
value.
The ECM willnow start toself-control
at its initial value. Engine operation can
vary slightly whentheterminal is
disconnected. However,thisisnot an
indication ofaproblem. Donot replace
parts because ofaslight variation.
WHEN STARTING
• Do not depress accelerator pedalwhen
starting.
• Immediately afterstarting, donot revup
engine unnecessarily .
• Do not revupengine justprior to
shutdown.
EC-8 WIRELESS
EQUIPMENT
• When installing C.B.hamradio ora
mobile phone, besure toobserve the
following asitmay adversely affect
electronic controlsystems depending
on itsinstallation location.
1) Keep theantenna asfar aspossible
away fromtheEGM.
2) Keep theantenna feederlinemore than
20 em (7.9 in)away fromtheharness
of electronic controls.
Do not letthem runparallel foralong
distance.
3) Adjust theantenna andfeeder lineso
that thestanding-wave ratiocanbe
kept smaller.
4) Be sure toground theradio tovehicle
body.
FUEL PUMP
• Do not operate fuelpump whenthere
is no fuel inlines.
• Tighten fuelhose clamps tothe
specified torque.
ECCS HARNESS HANDLING
• Securely connectEGGSharness
connectors.
A poor connection cancause an
extremely high(surge) voltage to
develop incoil and condenser, thus
resulting indamage toICs .
• Keep ECGS harness atleast 10em (3.9
in) away fromadjacent harnesses, to
prevent anEGGS system malfunction
due toreceiving externalnoise,
degraded operation ofIGs, etc.
• Keep EGCS partsandharnesses dry.
• Before removing parts,turnoffignition
switch andthen disconnect battery
ground cable.
