1. WINDSHIELD WASHER MOTOR AND PUMP ASSY
(a) Operation Check
(1) Pour the washer fluid into the washer jar with the
washer motor and the pump installed to the washer
jar assy.
(2) Connect the battery (+) to the terminal 1 of the wind-
shield washer motor and pump assy, the battery (±)
to the terminal 2 of the windshield washer motor and
pump assy. Check that the washer fluid comes out
from the washer jar.
2. REAR WASHER MOTOR ASSY
(a) Operation Check
(1) Pour the washer fluid into the washer jar with the
washer motor and the pump installed to the washer
jar assy.
(2) Connect the battery (+) to the terminal 1 of the rear
washer motor assy, the battery (±) to the terminal 2
of the rear washer motor assy. Check that the wash-
er fluid comes out from the washer jar.
3. HEADLAMP CLEANER MOTOR AND PUMP ASSY
(a) Operation Check
(1) Pour the washer fluid into the washer jar with the
washer motor and the pump installed to the washer
jar assy.
(2) Connect the battery (+) to the terminal 2 of the head-
lamp cleaner motor and pump assy, the battery (±)
to the terminal 1 of the headlamp cleaner motor and
pump assy. Check that the washer fluid comes out
from the washer jar.

6. AUTO WIPER SYSTEM OPERATION CHECK
(a) Spray once at the area where the rain sensor is placed, then the wiper blades immediately will carry
out a wiping cycle. If the water is continuos sprayed to the rain sensor area of the windscreen, the wiper
blades first should carry out interval mode, then change to low speed and finally reach high speed after
a few seconds.
By stopping spraying water to the screen the wiper blade changing back their speed until they stop
wiping.

POSITION TYPE)
(a) LO Operation Check
(1) Connect the battery (+) to the terminal 1 (+1) of the
connector and the battery (±) to the terminal 5 (E)
of the connector, and check that the motor operates
with low speed (LO).
(b) HI Operation Check
(1) Connect the battery (+) to the terminal 4 (+2) of the
connector and the battery (±) to the terminal 5 (E)
of the connector, and check that the motor operates
with high speed (HI).
(c) Automatic Stop Operation Check
(1) Connect the battery (+) to the terminal 1 (+1) of the
connector and the battery (±) to the terminal 5 (E)
of the connector. With the motor being rotated at low
speed (LO), disconnect the terminal 1 (+1) to stop
the wiper motor operation at any position except the
automatic stop position.
(2) Using SST, connect the terminal 1 (+1) and the ter-
minal 3 (S), and the battery (+) to the terminal 2 (B)
to restart the motor operation at low speed.
