1. Operation in low speed
With the motor connector terminal 2 lC-38l con­
nected
to the battery (+) terminal and the
connector3lC-38l
to the(-) terminal, check to see
if the motor rotates in low speed.
2. Operation in high speed
With the motor connector terminal 1 lC-38l con­
nected
to the battery (+) terminal and the
connector
3lC-38I to the(-) terminal, check to see
if the motor rotates in high speed.
3.
Stop operation
After stopping the windshield wiper in the
position on the
way by confirming the operation
at the
low speed in Item No.1.
When the connectors 2
lC-381 and 5 lC-381 are
connected,
while connecting the motor connector
terminal 6
IC-381 to the battery (+) terminal and
the connector 3
IC-381 to the H terminal, check
to see if the motor rotates at low speed and stops
at the auto-stop position.
Repair
or replace the motor when the results of
the above inspections are found abnormal.
