4) Drying wiring harness
If there is any oil or dirt on the wiring har-
ness, wipe it off with a dry cloth. Avoid
washing it in water or using steam. If the
connector must be washed in water, do
not use high-pressure water or steam
directly on the wiring harness. If water
gets directly on the connector, do as fol-
lows.
1] Disconnect the connector and wipe
off the water with a dry cloth.
a If the connector is blown dry with
compressed air, there is the risk
that oil in the air may cause
defective contact, so remove all
oil and water from the com-
pressed air before blowing with
air.
2] Dry the inside of the connector with a
dryer.
If water gets inside the connector, use
a dryer to dry the connector.
a Hot air from the dryer can be
used, but regulate the time that
the hot air is used in order not to
make the connector or related
parts too hot, as this will cause
deformation or damage to the
connector.
3] Carry out a continuity test on the con-
nector.
After drying, leave the wiring harness
disconnected and carry out a continu-
ity test to check for any short circuits
between pins caused by water.
a After completely drying the con-
n e c t o r, b l o w i t w i t h c o n ta c t
restorer and reassemble.
