(a) Turn the wiper switch to the INT position.
(b) Turn the intermittent time control switch to the FAST posi-
tion.
(c) Connect the positive (+) lead from the battery to terminal
16 and the negative (±) lead to terminal 2.
(d) Connect the positive (+) lead from the voltmeter to termi-
nal 7 and the negative (±) lead to terminal 2, and check
that the meter needle indicates battery positive voltage.
If operation is not as specified, replace the wiper and washer
switch.

6. High Speed:
INSPECT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and
the negative (±) lead from the battery to the motor body or termi-
nal 4, and check that the motor operates at high speed.
If operation is not as specified, replace the motor.
7. Stopping at Stop Position:
INSPECT WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor opera-
tion anywhere except at the stop position by disconnect-
ing positive (+) lead from terminal 5.
(b) Connect terminals 1 and 5.
(c) Connect the positive (+) lead from the battery to terminal
2 and the negative (±) lead from the battery to the motor
body or terminal 4, and check that the motor stops run-
ning at the stop position after the motor operates again.
If operation is not as specified, replace the motor.
8. INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (±) lead to terminal 1, and check that the motor op-
erates.
NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
If operation is not as specified, replace the motor.
