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.

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

HANDLING INSUFFICIENT REFRIGERANT LEVEL
If an insufficient refrigerant level is detected at troubleshooting,
do not charge (add) the refrigerant. Because an accurate amount of
refrigerant cannot be determined from the pressure indicated on the manifold
gauge, never charge the refrigeran ...
