ELECTRICAL SYSTEM

ELECTRICAL PARTS
Battery cable

·Before disconnecting connector or removing
electrical parts, disconnect the negative battery
cable.

Wiring Harness
·To remove the wiring harness from the clip in the
engine room, pry up the hook of the clip using a
flathead screwdriver.

CONNECTORS
Disconnecting connectors
·When disconnecting connector, grasp the
connectors, not the wires.

·Connectors can be disconnected by pressing or
pulling the lock lever as shown.

GI-8

Locking connector
·when locking connectors, listen for a click
indicating they are securely locked.

Inspection
·When a tester is used to inspect for continuity or
measuring voltage, insert the tester probe from
the wiring harness side.







·Inspect the terminals of waterproof connectors
from the connector side since they cannot be
accessed from the wiring harness side.

Caution

·To prevent damage to the terminal, wrap

a thin wire around the tester probe before

inserting into terminal

Terminals
Inspection
·Pull lightly on individual wires to verify that they

are secured in the terminal.

GI-9

Replacement
·Use the appropriate tools to remove a terminal as
shown. When installing a terminal, be sure to
insert it until it locks securely.
·Insert a thin piece of metal from the terminal side
of the connector and with the terminal locking tab
pressed down, pull the terminal out from the
connector.

Sensors, Switches, and Relays
·Handle sensors, switches, and relays carefully.
Do not drop them or strike them against other
objects.

Wiring Harness
Wiring color codes
·Two-color wires are indicated by a two-color code symbol.
·The first letter indicates the base color of the wire and the second the color of the stripe.

Fuse
Replacement
·When replacing a fuse, be sure to replace it with
one of the same capacity. If a fuse fails again, the
circuit probably has a short and the wiring should

be inspected.

·Be sure the negative battery terminal is
disconnected before replacing a main fuse.
·When replacing a pullout fuse, use the fuse
puller.

ELECTRICAL TROUBLESHOOTING TOOLS
Jumper wire
·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
wiring harnesses or electronic
components.

Voltmeter
·The DC voltmeter is used to measure circuit
voltage. A voltmeter with a range of 15V 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.




Ohmmeter
·The ohmmeter is used to measure the resistance
between two points in a circuit and to inspect for
continuity and short circuits.
Caution
·Do not connect the ohmmeter to any

circuit where voltage is applied. This will

damage the ohmmeter.
