Foreword, safety and general information
Check that there is no oil, dirt or water stick
to the connector pins (joint portion).
Check that the connector pins are free from
deformation, defective contact, corrosion, or
damage.
Check that external surfaces of the
connectors are free from damage or
breakage.
a If any oil, water or dirt is stuck to the
connector, wipe it off with a dry cloth. If any
water is inside the connector, warm the
connector and the inside of the wiring
harness with a dryer. But be careful not to
make it too hot as it causes short circuit.
a If there is any damage or breakage, replace
the connector.
2. Fix the connector securely.
Align the connectors correctly, and fit them
securely. For the connectors with the lock
stopper, push in the connectors until "click" is
heard.
3. Correct the protrusion of the boot and
misalignment of the wiring harness
For connectors fitted with the boot, correct
any extrusion of the boot. In addition, if the
wiring harness or the clamp is out of the
position, put it in its original position.
a If the connector cannot be corrected
easily, remove the clamp and adjust the
position.
