International Symbols

International symbols are used throughout the wiring diagrams. These symbols are consistent with those being used
around the world. See How to Read Electrical Schematics in Section 01 General Information.

GENERAL INFORMATION

BESMW010001T

Below is a list of the symbols and their definitions that are used in the electrical schematics.

NUMBER

ITEM

DESCRIPTION

Power source

This represents the condition when the system receives battery
positive voltage.

Fuse

The single line represents that this is a fuse.

Current rating

This represents the current rating of the fuse.

Fuse location

This represents the location of the fuse in the Power Fuse Box or
Front Fuse and Relay Box.

Connectors

This represents connector E-101 is female and connector C-101 is
male.

Terminal number

This represents the terminal number of a connector.

Component name

This represents the name of a component.

Connector number

This represents the connector number.
The letter represents which harness the connector is located in.

Splice

The shaded circle represents that the splice is always on the
vehicle.

Optional splice

The open circle represents that the splice is optional depending on
vehicle application.

Option abbreviation

This represents that the circuit is optional depending on vehicle
application.

Ground (GND)

This represents the ground connection. (See Ground Distribution in
Section 16 Wiring).
Ground connector number has no view face.

Page crossing

This arrow represents that the circuit continues to an adjacent page.
The

⬙A⬙ corresponds with the ⬙A⬙ on the adjoining page of the

electrical schematic.

Data link

This represents that the system branches to another system
identified by cell data code.

Option description

This represents a description of the option abbreviation used on the
page.

Connector views

This represents the connector information.
This component side is described by the connector symbols.

Connector color

This shows a code for the color of the connector:
B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
BR = Brown
O = Orange
GR = Gray

Shielded line

The line enclosed by broken line circle represents shielded wire.

Light-emitting diodes

As an illumination tool, in the circuit and instrument cluster.

GENERAL INFORMATION

ELECTRICAL TROUBLESHOOTING

Troubleshooting Wiring Problems

When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and
explained below. Always check for non-factory equipped components added to the vehicle before doing any diagno-
sis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the
problem.

Perform the following when troubleshooting a wiring problem:

1. Verify the problem.

2. Verify any related symptoms (do this by performing operational checks on components that are in the same

circuit).

3. Analyze the symptoms (use the wiring diagrams to determine what the circuit is doing, where the problem most

likely is occurring and where the diagnosis will continue).

4. Isolate the problem area.

5. Repair the problem area.

6. Verify the proper operation (for this step, check for proper operation of all items on the repaired circuit).

Testing For Voltage

1. Connect the ground lead of a voltmeter to a known good ground.

2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON

to check voltage. Refer to the appropriate test procedure.

Testing For Continuity

1. Remove the fuse for the circuit being checked or, disconnect the battery.

2. Connect one lead of the ohmmeter to one side of the circuit being tested.

3. Connect the other lead to the other end of the circuit being tested (low or no resistance means good continuity).

Testing For A Short To Ground

1. Remove the fuse and disconnect all items involved with the fuse.

2. Connect a test light or a voltmeter across the terminals of the fuse.

3. Starting at the fuse block, wiggle the wiring harness about six to eight inches apart and watch the voltmeter/test

light.

4. If the voltmeter registers voltage or the test light glows, there is a short to ground in that general area of the

wiring harness.

Intermittent and Poor Connections

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a
sticking component or relay to cause a problem. Before condemning a component or wiring assembly, check the
following items:

1. Connectors are fully seated

2. Spread terminals, or terminal push out

3. Terminals in the wiring assembly are fully seated into the connector/component and locked into position

4. Dirt or corrosion on the terminals (any amount of corrosion or dirt could cause an intermittent problem)

5. Damaged connector/component casing exposing the item to dirt or moisture

6. Wire insulation that has rubbed through causing a short to ground

7. Some or all of the wiring strands broken inside of the insulation

8. Wiring broken inside of the insulation

ELECTRICAL TROUBLESHOOTING TOOLS

Jumper Wires

• A jumper wire is used to create a temporary circuit.

Connect the jumper wire between the terminals of
a circuit to bypass a switch.

CAUTION:
Do not connect a jumper wire from the power
source line to a body ground. This may cause
burning or other damage to wiring harnesses
or electronic components.

Voltmeter

• The DC voltmeter is used to measure circuit volt-

age. A voltmeter with a range of 15 V or more is
used by connecting the positive (+) probe (red lead
wire) to the point where voltage will be measured
and the negative (-) probe (black lead wire) to a
body ground.
