PRECAUTIONS
 If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.
 After installing plate clamps, apply force to them in the direction of
the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000003852785
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
 Avoid prolonged and repeated contact with oils, particularly used engine oils.
 Wear protective clothing, including impervious gloves where practicable.
 Do not put oily rags in pockets.
 Avoid contaminating clothes, particularly underpants, with oil.
 Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
 First aid treatment should be obtained immediately for open cuts and wounds.
 Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
 Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
 Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
 If skin disorders develop, obtain medical advice without delay.
 Where practical, degrease components prior to handling.
 Where 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
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
Air ConditioningINFOID:0000000003852786

 Do not apply excessive shock to the control unit by dropping or hit-
ting it.
 Be careful to prevent condensation in the control unit due to rapid
temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
 Be careful not to let oil to get on the control unit connector.
 Avoid cleaning the control unit with volatile oil.
 Do not disassemble the control unit, and do not remove the upper
and lower covers.
 When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit from
damaging battery voltage because of short circuiting.
 When checking input and output signals of the control unit, use the
specified check adapter.
Intermittent IncidentINFOID:0000000003852795
DESCRIPTION
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 fol-
lowing 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: Vehicle vibration
 Heat sensitive
 Freezing
 Water intrusion
 Electrical load
 Cold 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 following illustra-
tion.
Connector & Harness
SAIA0255E
SEF348N

GI-36
< BASIC INSPECTION >
SERVICE INFORMATION FOR ELECTRICAL INCIDENT
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 termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, 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.
Sensor & Relay
Gently apply 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.
Engine Compartment
There are several reasons a vehicle or engine vibration could cause an electrical complaint. Some of the
things to check for are:
 Connectors not fully seated.
 Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
 Wires laying across brackets or moving components.
 Loose, dirty or corroded ground wires.
 Wires routed too close to hot components.
To inspect components under the hood, start by verifying the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently 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. Vehi-
cle 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 vibration. If the wiring runs under seating areas, inspect wire routing for possible damage or
pinching.
HEAT SENSITIVE
 The customer's concern 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.
CAUTION:
Do not heat components above 60°C (140°).
 If incident occurs while heating the unit, either replace or properly
insulate the component.

 The customer may indicate the incident goes away after the car
warms up (winter time). The cause could be related to water freez-
ing somewhere in the wiring/electrical system.
 There are two methods to check for this. The first is to arrange for
the owner to leave his car overnight. Make sure it will get cold
enough to demonstrate his complaint. Leave the car parked out-
side overnight. In the morning, do a quick and thorough diagnosis
of those electrical components which could be affected.
 The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair or
replace the component.
WATER INTRUSION
The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water intru-
sion on an electrical part. This can be simulated by soaking the car
or running it through a car wash.
CAUTION:
Do not spray water directly on any electrical components.
ELECTRICAL LOAD
The incident may be electrical load sensitive. Perform diagnosis with
all accessories (including A/C, rear window defogger, radio, fog
lamps) turned on.
COLD OR HOT START UP
On some occasions an electrical incident may occur only when the car is started cold, or it may occur when
the car is restarted hot shortly after being turned off. In these cases you may have to keep the car overnight to
make a proper diagnosis.
Circuit InspectionINFOID:0000000003852796
DESCRIPTION
 In general, testing electrical circuits is an easy task if it is approached in a logical and organized method.
Before beginning it is important to have all available information on the system to be tested. Also, get a thor-
ough understanding of system operation. Then you will be able to use the appropriate equipment and follow
the correct test procedure.
 You may have to simulate vehicle vibrations while testing electrical components. Gently shake the wiring
harness or electrical component to do this.
