Precautions for Multiport Fuel Injection
System or Engine Control Module
lBefore connecting or disconnecting any harness connector
for the multiport fuel injection system or ECM (Engine Con-
trol Module):
Turn ignition switch to ªLOCKº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Three Way Catalyst
If a large amount of unburned fuel flows into the catalyst, the
catalyst temperature will be excessively high. To prevent this,
follow the instructions below:
lUse unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
lWhen checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
lDo not run engine when the fuel tank level is low, otherwise
the engine may misfire causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
lAlways use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
lAvoid accelerating engine to a high rpm immediately after
starting.
lIf engine had been operating at high rpm for an extended
period of time, let it idle for a few minutes prior to shutting it
off.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
lAvoid prolonged and repeated contact with oils, particularly
used engine oils.

PRECAUTIONS
GI-6

lWear protective clothing, including impervious gloves where
practicable.
lDo not put oily rags in pockets.
lAvoid contaminating clothes, particularly underpants, with oil.
lHeavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
lFirst Aid treatment should be obtained immediately for open
cuts and wounds.
lUse barrier creams, applying them before each work period,
to help the removal of oil from the skin.
lWash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations contain-
ing lanolin replace the natural skin oils which have been
removed.
lDo not use gasoline, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
lIf skin disorders develop, obtain medical advice without
delay.
lWhere practicable, degrease components prior to handling.
lWhere there is a risk of eye contact, eye protection should
be worn, for example, chemical goggles or face shields; in
addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating
system must meet the requirements of HM Inspectorate of Pol-
lution for small burners of less than 0.4 MW. If in doubt check
with the appropriate local authority and/or manufacturer of the
approved appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local author-
ity for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or
drains, or into water courses.
The regulations concerning the pollution of the environment
will vary between regions.
Precautions for Fuel
GASOLINE ENGINE:
Unleaded gasoline of at least 95 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the catalytic converter.
DIESEL ENGINE*:
Diesel fuel of at least 50 cetane
* If two types of diesel fuel are available, use summer or win-
ter fuel properly according to the following temperature con-
ditions.
lAbove þ7ÉC (20ÉF) ... Summer type diesel fuel.
lBelow þ7ÉC (20ÉF) ... Winter type diesel fuel.

Incident Simulation Tests
INTRODUCTION
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The
following section illustrates ways to simulate the conditions/environment under which the owner experiences
an electrical incident.
The section is broken into the six following topics:
lVehicle vibration
lHeat sensitive
lFreezing
lWater intrusion
lElectrical load
lCold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of
the problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle
with A/C on). In such a case, you will want to check for a vibration related condition. Refer to the illustration
below.
Connectors & harness
Determine which connectors and wiring harness would affect the electrical system you are inspecting.Gently
shake each connector and harness while monitoring the system for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
Hint
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector ter-
minals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs
intermittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean
the terminals on related connectors in the system.
Sensors & relays
Gentlyapply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
SGI839 Vibration test
Shake gently.
Bend gently.Tap gently.
HOW TO PERFORM EFFICIENT DIAGNOSIS
FOR AN ELECTRICAL INCIDENT
GI-25

Engine compartment
There are several reasons a vehicle or engine vibration could
cause an electrical complaint. Some of the things to check for
are:
lConnectors not fully seated.
lWiring harness not long enough and is being stressed due
to engine vibrations or rocking.
lWires laying across brackets or moving components.
lLoose, dirty or corroded ground wires.
lWires routed too close to hot components.
To inspect components under the hood, start by verifying the
integrity of ground connections. (Refer to GROUND INSPEC-
TION described later.) First check that the system is properly
grounded. Then check for loose connection bygently shaking
the wiring or components as previously explained. Using the
wiring diagrams inspect the wiring for continuity.
Behind the instrument panel
An improperly routed or improperly clamped harness can
become pinched during accessory installation. Vehicle vibration
can aggravate a harness which is routed along a bracket or near
a screw.
Under seating areas
An unclamped or loose harness can cause wiring to be pinched
by seat components (such as slide guides) during vehicle vibra-
tion. If the wiring runs under seating areas, inspect wire routing
for possible damage or pinching.
HEAT SENSITIVE
The owner's problem may occur during hot weather or after car
has sat for a short time. In such cases you will want to check for
a heat sensitive condition.
To determine if an electrical component is heat sensitive, heat
the component with a heat gun or equivalent.
Do not heat components above 60ÉC (140ÉF).If incident
occurs while heating the unit, either replace or properly insulate
the component.
SGI842 Heating test
Heat gun
Do not heat above 60ÉC (140ÉF).
