4. HOW TO DETERMINE A
SHORT-CIRCUIT
1) Test lamp method:
Connect a test lamp (rated at approximately 3
watts) in place of the blown fuse and allow current
to flow through the circuit. Disconnect one connec-
tor at a time from the circuit, starting with the one
located farthest from the power supply. If the test
lamp goes out when a connector is disconnected,
the wiring between that connection and the next
connector (farther from the power supply) is
shorted.
G6M0210
2) Ohmmeter method:
Disconnect all affected connectors, and check con-
tinuity between each connector and ground. When
ohmmeter indicates continuity between a particular
connector and ground, that connector is shorted.
G6M0211
3. Working Precautions
A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
1) When working under a vehicle which is jacked-
up, always be sure to use safety stands.
2) The parking brake must always be applied dur-
ing working. Also, in automatic transmission
vehicles, keep the select lever set to the P (Park-
ing) range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, espe-
cially the radiator and exhaust system immediately
after the engine has been shut off.
B: PRECAUTIONS IN TROUBLE
DIAGNOSIS AND REPAIR OF
ELECTRIC PARTS
1) The battery cable must be disconnected from
the battery's (þ) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere
with the body end parts or edges and bolts or
screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull
the wires, but pull while holding the connector
body.

F: CONNECTOR SKETCH
IEach connector sketch clearly identifies the
shape and color of a connector as well as terminal
locations. Non-colored connectors are indicated in
natural color.
IWhen more than two types of connector number
are indicated in a connector sketch, it means that
the same type connectors are used.
G: GROUND
Each grounding point can be located easily by
referring to the corresponding wiring harness.
H: DIODE
A symbol is used to indicate a diode.
I: WIRE TRACING ON EXTENDED
WIRING DIAGRAMS
For a wiring diagram extending over at least two
pages, a symbol (consisting of the same charac-
ters with arrows), as shown below, facilitates wire
tracing from one page to the next.
A¨A, B¨B
J: SYMBOLS OF WIRE
CONNECTION AND CROSSING
B6M0750A
K: POWER SUPPLY ROUTING
A symbol is used to indicate the power supply in
each wiring diagram.
ªMB-5º, ªMB-6º, etc., which are used as power sup-
ply symbols throughout the text, correspond with
those shown in the POWER SUPPLY ROUTING in
the wiring diagram.
Accordingly, using the POWER SUPPLY ROUT-
ING and wiring diagrams permits service person-
nel to understand the entire electrical arrangement
of a system.
L: S.M.J.
A symbol is used to indicate the terminal arrange-
ment of the super multiple junction. The S.M.J. is
not shown in respective wiring diagrams but is indi-
cated on the next page.
M: SYMBOLS AND
ABBREVIATIONS
A number of symbols and abbreviations are used
in each wiring diagram to easily identify parts or
circuits.
