Electrical System

Electrical Parts




Battery cable
- Before disconnecting connectors or removing electrical parts, disconnect the negative battery cable.

Connectors




Data link connector
- Insert the probe into the service hole when connecting a jumper wire to the data link connector.

CAUTION: Inserting a jumper wire probe into the data link connector terminal may damage the terminal.

Disconnecting connectors




- When disconnecting two connectors, grasp the connectors, not the wires.




- 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
- When a tester is used for checking continuity or measuring voltage, insert the tester probe from the wiring harness side.




- Check 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 lead before inserting Into terminal.

Terminals




Inspection
- Pull lightly on individual wires to check that they are secured in the terminal.




Replacement
- Use the appropriate tools to remove a terminal as shown. While 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 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 checked.
- Be sure the negative battery terminal is disconnected before replacing a main fuse.
- When replacing a pullout fuse, use the fuse puller.
