Mazda 6 Service Manual: Connectors

Data link connector

• Insert the probe into the terminal 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 connector, 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 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.

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.

Direction of View for Connector

Part-side connector

Direction of view is from the terminal side.

* : Part names are shown only when there are multiple connector drawings.

Vehicle-harness-side connector

Direction of view is from the harness side.

* : Part names are shown only when there are multiple connector drawings.

Other

Because vehicle-harness-side connectors, such as the DLC 2, have to be viewed from the terminal side, the direction of view is from the terminal side.
