Electrical Parts

Battery cable

• Before disconnecting connectors 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.

Caution

• Do not remove the harness protective tape. Otherwise, the wires could rub against the body, which could result in water penetration and electrical shorting.

Connectors

Disconnecting connectors

• When disconnecting connector, grasp the connectors, not the wires.

am6xuw00000039

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

Locking connector

• When locking connectors, listen for a click indicating they are securely locked.

Inspection

Caution

• To prevent damage to the terminal, wrap a thin wire around the tester probe before inserting into terminal.

• 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.

Terminals

Inspection

• Pull lightly on individual wires to verify that they are secured in the terminal.

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

Caution

• Do not connect a jumper wire from the power source line to a body ground. This may cause burning or other damage to wiring harnesses or electronic components.

• A jumper wire is used to create a temporary circuit. Connect the jumper wire between the terminals of a circuit to bypass a switch.

Voltmeter

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

Caution

• Do not connect the ohmmeter to any circuit where voltage is applied. This will damage the ohmmeter.

• The ohmmeter is used to measure the resistance between two points in a circuit and to inspect for continuity and short circuits.

Precautions Before Welding

1.Switch the ignition to LOCK.

2.Disconnect the battery cables.
