WIRE COLORS IN CIRCUIT DIAGRAM
Colored wire as shown in the following tables are used.
When two colors are used in a wire, the designation of the wireis as follows.

GENERAL
CONNECTOR CLASSIFICATIONS
Electrical wiring connectors are classified according to the wiring parts.
A connector identification symbol consists of a wiring harness location classification symbol corresponding to eachwiring harness location and number peculiar to the connector.
These connector locations can be found in the WIRING HARNESS LAYOUT.
Number peculiar to sub connector (Serial number)
Number peculiar to main connector (Serial number)Symbol indicating wiring harness (Engine wiring harness)
NOTE
Connectors which connect each wiring harness are represented by the following symbols.For example;

GENERAL
CONNECTOR IDENTIFICATION SYMBOLS
Connectors and connector pin numbers are indicated in eachcircuit. Wires and pins of the connectors are also clearlyillustrated.Identifying the difference between the male or female connector
is determined from the pin type of a connector.

TROUBLESHOOTING PROCEDURES
TROUBLESHOOTING PROCEDURES
TESTING FOR VOLTAGE
1. Connect one lead of a test lamp or voltmeter to a ground.If you are using a voltmeter, be sure it is the voltmeter’snegative lead that you have connected to ground.
2. Connect the other lead of the test lamp or voltmeter to aselected test point (connector or terminal).
3. If the test lamp glows, there is voltage present. If you areusing a voltmeter, note the voltage reading.A loss of more than 1 volt from specifications indicates aproblem.
7
TROUBLESHOOTING PROCEDURES
TESTING FOR CONTINUITY
1. Disconnect the battery.2. Connect one lead of a self-powered test lamp or ohmmeter
to one end of the part of the circuit you wish to test.3. Connect the other lead to the other end.4. If the self-powered test lamp glows, there is continuity.
If you are using an ohmmeter, low or zero resistance meansgood continuity.
8
TROUBLESHOOTING PROCEDURES
TESTING FOR SHORT TO GROUND
1. Remove the blown fuse and disconnect the battery and load.2. Connect one lead of a self-powered test lamp or an
ohmmeter to the fuse terminal on the load side.
3. Connect the other lead to a ground.
4. Beginning near the fuse block move the harness from sideto side. Continue this point (about six inches apart) while
watching the test lamp or ohmmeter.5. When the test lamp glows, or ohmmeter registers, there is
a short to ground in the wiring near that point.
9
TROUBLESHOOTING PROCEDURES
TROUBLESHOOTING TOOLS
1. A TEST LAMP is made of a 12-Volt bulb with a pair of leads
attached. After grounding one lead, touch the other lead tovarious points along the circuit where voltage should be
present. When the bulb glows, there is voltage at the pointbeing tested.
2. SELF-POWERED TEST LAMP
NOTE
A self-powered test lamp is only used on an unpoweredcircuit. Use a self-powered test lamp to check forcontinuity.
This tool is made of a bulb, battery and two leads. If the leadsare touched together, the bulb will glow.
3. A JUMPER WIRE is made of an in-line fuse holder connectedto a set of test leads.
It can be used for by-passing open circuits.
CAUTION
Never use a jumper wire between an electrical source and
ground.
4. A VOLTMETER can be used instead of a test lamp. Whilea test lamp shows whether or not voltage is present, avoltmeter indicates how much voltage is present.
5. A OHMMETER can be used instead of a self-powered testlamp. The ohmmeter shows how much resistance there is
between two points along a circuit. Low resistance meansgood continuity.
6. A DIGITAL MULTIMETER can be used instead of anohmmeter, voltmeter or an ammeter.

TROUBLESHOOTING PROCEDURES
WIRING HARNESS TROUBLESHOOTING
The most important thing in troubleshooting is to determine“probable causes”. The determination of the probable causesmust be based on a theory and be supported by facts and mustnot be based on intuition.
TROUBLESHOOTING STEPS
If an attempt is made to solve a problem without correct stepsfor troubleshooting, the problem can be more complicated,resulting in failure to determine the causes correctly and makingincorrect repairs.
The steps below should be followed in troubleshooting.
1. Observe the symptom carefully.Check if there are also other problems.
2. In determining the probable causes, it is necessary to checkthe circuit diagram to understand the circuit as a system the
causes of same problems in the past must be taken intoaccount.
3. Troubleshooting is performed by making step by step checksuntil the cause is found.
4. After the problems are solved, be sure to check that thesystem operates correctly.
