PRECAUTIONS FOR DISCONNECTION AND CONNECTION OF CON-
NECTORS
1.
Disconnect the connector and wipe off the water with a dry
cloth.
NOTICE
If the connector is to be blown with dry compressed
air, there is the risk that oil in the air may cause defec-
tive contact, remove oil and water in the air before
starting air blow.
2.
Dry the inside of the connector with a dryer.
If water enters inside the connector, use a dryer to dry the
connector.
NOTICE
Hot air from a dryer can be used, but limit the time of
using a dryer to prevent the connector or related parts
from becoming too hot, as this will cause deformation
or damage to the connector.
3.
Perform a continuity test on the connector.
After drying, leave the wiring harness disconnected, con-
nect T-adapter(1), and perform a continuity test to check
for any short circuits between pins caused by water or etc.
REMARK
After the connector is completely dried, blow the contact
restorer, and reassemble them.
