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.

(5) Connect the battery (±) to the terminal 16 (+S) of the
connector. Operate the intermittent wiper relay and
check voltage between terminal 7 (+1) and terminal
2 (EW).
(c) Operation Check (Front Wiper)
(1) Turn the wiper switch into OFF position.
(2) Connect the battery (+) to the terminal 17 (+B) of the
connector, the battery (±) to the terminal 16 (+S)
and the terminal 2 (EW) of the connecter.
(3) Connect the voltmeter (+) terminal to the terminal 7
(+1) of the connector and the voltmeter (±) terminal
to the terminal 2 (EW) of the connector. Turn the
washer switch ON and OFF, and check voltage be-
tween terminal 7 (+1) and terminal 2 (EW).

7. HEADLAMP CLEANER CONTROL RELAY
(a) w/o HID:
Inspect headlamp cleaner control relay operation
(1) Check that no continuity exists between the termi-
nals 2 and the terminal 3.
(2) Connect the positive (+) lead from the battery to the
terminal 1 and the terminal 5, and the negative (±)
lead from the battery to the terminal 3.
(3) Connect the negative (±) lead from the battery to the
terminal 4, and check that continuity exists between
the terminal 2 and the terminal 5 for 0.8 to 0.9 se-
conds, then no continuity exists.
(b) w/ HID:
Inspect headlamp cleaner control relay operation
(1) Check that no continuity exists between the termi-
nal 2 and the terminal 5.
(2) Connect the positive (+) lead from the battery to the
terminal 1, and the negative (±) lead from the bat-
tery to the terminal 5.
(3) Connect the negative (±) lead from the battery to the
terminal 4, and check that continuity exists between
the terminal 2 and the terminal 5 for 0.7 to 0.9 se-
conds, then no continuity exists.
(4) Disconnect the positive (+) lead from the battery
from the terminal 1, and connect the positive (+)
lead from the battery to the terminal 1 again.
