2) Connecting connectors
1] Check the connector visually.
Check that no oil, dirt, or water is stuck to
connector pins (joint portion).
Check that 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 there is any oil, water, or dirt stuck to
the connector, wipe it off with a dry
cloth. If any water has got inside the
connector, warm the inside of the con-
nector and harness with a dryer, but
be careful not to make them too hot as
this will cause short circuits.
a If there is any damage or breakage,
replace the connector.
2] Fix the connector securely.
Position the connectors correctly, and
then fit them securely. For connectors
with the lock stopper, push in the
connector until the stopper clicks into
position.
3] Correcting protrusion of the boot and
misalignment of the wiring harness
For connectors fitted with the boot,
correct any extrusion of the boot. In addi-
tion, if the wiring harness is moved in
laying, or the clamp is out of position,
correct it to its right position.
a If the connector cannot be corrected
easily, remove the clamp and adjust
the position.
q
If the connector clamp is removed, be
sure to return it to its original position.
Check also that there are no loose
clamps.
