FOREWORD
E. Drying wiring harness
• If there is any oil or dirt on the wiring harness, 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 follows.
• Disconnect the connector and wipe off the water with a
dry cloth.
★ 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
compressed air before blowing with air.
• Dry the inside of the connector with a dryer.
• If water gets inside the connector, use a dryer to dry the
connector.
★ 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.
• Perform a continuity test on the connector.
• After drying, leave the wiring harness disconnected and
perform a continuity test to check for any short circuits
between pins caused by water.
★ After completely drying the connector, blow it with
contact restorer and reassemble.
