Basic checks
DISCONNECTING CONNECTORS

Always hold the connector itself.
CAUTION:
Don’t pull the harness.

To disconnect a locking connector, first re-lease
the lock, then pull the connector off.


Insert a connector by pushing it all the way in. If
the connector is equipped with a locking device,
push it in until a clicking sound is heard.

INSERTING A PROBE

Generally, probes are inserted into connectors from the rear.

Connectors equipped with shock protectors must be checked
with a mini probe (thin), or it will be necessary to remove the shock
protector.

When removing the shock protector take care not to deform it;
this also applies to waterproof connectors, which cannot be tested
from the wire side.

When the connector has a back plate, remove the plate after
removing the projection of the plate first. (Be careful not to use
excessive force, since the terminals might brake off).
