1) Turn the ignition switch to OFF.
2) Remove the MAIN SBF, SBF 8 and fuse
(No. 12), and then check those are not blown
out.
Is the fuse blown out? Replace the fuse.
If the replaced
fuse has blown out
easily, repair the
short circuit of har-
ness of each fuse.

Basic Diagnostic Procedure
WIRING SYSTEM
1. Basic Diagnostic Procedure
A: BASIC PROCEDURES
1. GENERAL DESCRIPTION
The most important purpose of diagnostics is to
quickly determine which part is malfunctioning, to
save time and labor.
2. IDENTIFICATION OF TROUBLE SYMP-
TOM
Determine what the problem is based on the symp-
tom.
3. PROBABLE CAUSE OF TROUBLE
Look at the wiring diagram and check the system’s
circuit. Then check the switch, relay, fuse, ground,
etc.
4. LOCATION AND REPAIR OF TROUBLE
1) Using the diagnostics, narrow down the causes.
2) If necessary, use a voltmeter, ohmmeter, etc.
3) Before replacing certain component parts
(switch, relay, etc.), check the power supply,
ground, for open wiring harness, poor connectors,
etc. If no problem is encountered, check the com-
ponent parts.
5. SYSTEM OPERATION CHECK
After repairing, ensure that the system operates
properly.
B: BASIC INSPECTION
1. VOLTAGE MEASUREMENT
1) Using a voltmeter, connect the negative lead to a
good ground point or negative battery terminal and
the positive lead to the connector or component ter-
minal.
2) Contact the positive lead of the voltmeter on
connector (A). The voltmeter will indicate a voltage.
3) Shift the positive lead to connector (B). The volt-
meter will indicate no voltage.
4) With the test set-up held as it is, turn the switch
ON. The voltmeter will indicate a voltage and, at the
same time, the light will come on.
5) The circuit is in good order. If a problem such as
a light failing to illuminate occurs, use the proce-
dures outlined above to track down the malfunc-
tion.
2. CIRCUIT CONTINUITY CHECKS
1) Disconnect the battery terminal or connector so
there is no voltage between the check points.
Contact the two leads of an ohmmeter to each of
the check points.
If the circuit has diodes, reverse the two leads and
check again.
2) Use an ohmmeter to check for diode continuity.
When contacting the negative lead to the diode
positive side and the positive lead to the negative
side, there should be continuity.
When contacting the two leads in reverse, there
should be no continuity.
3) The symbol“ — ” indicates that continuity
exists between two points or terminals. For exam-
ple, when a switch position is at “3”, continuity ex-
ists among terminals 1, 3 and 6, as shown in the
table below.

Basic Diagnostic Procedure
WIRING SYSTEM
1. RELAY
A symbol used to indicate a relay.
2. CONNECTOR 1
The sketch of the connector indicates the one-pole
types.
3. WIRING CONNECTION
Some wiring diagrams are indicated in foldouts for
convenience. Wiring destinations are indicated
where necessary by corresponding symbols.
(When two pages are needed for clear indication)
4. FUSE NO. & RATING
The “FUSE No. & RATING“ corresponds with that
used in the fuse box (main fuse box, fuse and joint
box).
5. CONNECTOR 2
•Each connector is indicated by a symbol.
•Each terminal number is indicated in the corre-
sponding wiring diagram in an abbreviated form.
•For example, terminal number "G4" refers to No.
4 terminal of connector (G: F41) shown in the con-
nector sketch.
6. CONNECTOR SKETCH
•Each connector sketch clearly identifies the
shape and color of a connector as well as terminal
locations. Non-colored connectors are indicated in
white or natural color.
•When more than two types of connector number
are indicated in a connector sketch, it means that
the same type connectors are used.
7. GROUND
Each grounding point can be located easily by re-
ferring to the corresponding wiring harness.
8. DIODE
A symbol is used to indicate a diode.
9. WIRE TRACING ON EXTENDED WIRING
DIAGRAMS
For a wiring diagram extending over at least two
pages, a symbol (consisting of the same characters
with arrows), facilitates wire tracing from one page
to the next.
A ←→ B, B ←→ B
10.SYMBOLS OF WIRE CONNECTION AND
CROSSING
11.POWER SUPPLY CIRCUIT
A symbol is used to indicate the power supply in
each wiring diagram.
“MB-5”, “MB-6”, etc., which are used as power-
supply symbols throughout the text, correspond
with those shown in the “DC POWER SUPPLY
CIRCUIT” in the wiring diagram.
Accordingly, using the “DC POWER SUPPLY CIR-
CUIT” and wiring diagrams permits service person-
nel to understand the entire electrical arrangement
of a system.
12.CLASSIFICATION BY SPECIFICATION
When the wiring diagram differ according to vehicle
specifications, the specification difference is de-
scribed by using abbreviations.
