< BASIC INSPECTION >

3. Set crimp terminal to the die (tooth) of crimping tool [SST: J-

48817-8].

CAUTION:

Use appropriate die (tooth) of crimping tool [SST: J-48817-

8] according to the crimp terminal size.

4. Apply load until the handle of crimping tool [SST: J-48817-8 is

released.

NOTE:

The handle of the specified crimping tool [SST: J-48817-8] is not

opened until crimping is completed.

5. After crimping both sides, pull wire at both ends to check that

they are not disconnected from crimp terminals.

6. Cover the crimp terminal with heat shrinkable tube and heat

the tube with industrial dryer .

7. After heating heat shrinkable tube , check that adhesive is

squeezed out from both ends of tube to the entire perimeter.

HOW TO EXTEND WIRES

When repairing a broken aluminum wire, it can be extended by con-
necting aluminum wire with copper wire by using crimp terminal

Intermittent Incident

INFOID:0000000011278279

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

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.

< BASIC INSPECTION >

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°F).

• If incident occurs while heating the unit, either replace or properly

insulate the component.

FREEZING

• 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

SGI842

SGI843

GI-46

< BASIC INSPECTION >

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

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 Inspection

INFOID:0000000011278280

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.

NOTE:

Refer to

GI-39, "How to Check Terminal"

to probe or check terminal.

TESTING FOR “OPENS” IN THE CIRCUIT

SGI844

SGI845

OPEN

A circuit is open when there is no continuity through a section of the circuit.

SHORT

There are two types of shorts.

• SHORT CIRCUIT

When a circuit contacts another circuit and causes the normal resistance to
change.

• SHORT TO GROUND

When a circuit contacts a ground source and grounds the circuit.
