CAUTIONS IN SERVICING

When performing works related to electric systems, observe fol-

lowing cautions for the purpose of protection of electrical parts and

prevention of a fire from occurrence.

D When removing the battery from the vehicle or disconnecting the

cable from the battery terminals for inspection or service works

on the electric systems, always confirm first that the ignition

switch and all the other switches have been turned OFF. Other-

wise, the semi-conductor part may be damaged.

D When disconnecting cables from the battery, be sure to discon-

nect the one from the negative (–) terminal first and then the oth-

er from the positive (+) terminal.

D Reverse the above order when connecting the cables to the bat-

tery terminals.

D When disconnecting connectors, never pull the wiring har-

nesses. Unlock the connector lock first and then pull them apart

by holding connectors themselves.

D When connecting connectors, also hold connectors and push

them together until they lock securely (a click is heard).

8-2 BODY ELECTRICAL SYSTEM

GENERAL DESCRIPTION

The body electrical components of this vehicle are designed to operate on 12 Volts power supplied by the battery.

The electrical system utilizes negative ground polarity.

D When installing the wiring harness, fix it with clamps so that no

slack is left.

D When installing vehicle parts, be careful so that the wiring har-

ness is not interfered with or caught by any other part.

D To avoid damage to the harness, protect its part which may con-

tact against a part forming a sharp angle by winding tape or the

like around it.

D When replacing a fuse, make sure to use a fuse of the specified

capacity. Use of a fuse with a larger capacity will cause a dam-

age to the electrical parts and a fire.

D Always be careful not to handle electrical parts (computer, relay,

etc.) in a rough manner or drop them.

BODY ELECTRICAL SYSTEM 8-3

D When performing a work that produces a heat exceeding 805C

in the vicinity of the electrical parts, remove the heat sensitive

electrical part(s) beforehand.

D Use care not to expose connectors and electrical parts to water

which will be a cause of a trouble.

D When using a tester for checking continuity or measuring volt-

age, be sure to insert the tester probe from the wire harness

side.

WIRE COLOR SYMBOLS

The wire color is abbreviated to the first (or first two) alphabet(s) of

each color.

There are two kinds of colored wire used in this vehicle. One is

single-colored wire and the other is dual-colored (striped) wire.

The single-colored wire uses only one color symbol (i.e. “G”).

The dual-colored wire uses two color symbols (i.e. “G/Y”). The first

symbol represents the base color of the wire (“G” in the figure) and

the second symbol represents the color of the stripe (“Y” in the fig-

ure).
