WIPER AND WASHER
EXTERIOR
51-8
• The windshield washer is a 2-nozzle and 6-jet
type.
• The windshield washer nozzle with the integral
check valve has been adopted to prevent the
washer fluid from running down, and to improve
the response to switch operation.
• The washer motor for both of a windshield
washer motor and a rear washer motor has been
installed to reduce the weight.
• Washer-linked wiper function* has been adopted.
The washer fluid can be injected without operat-
ing the wiper. When the ignition switch is turned
ON while the washer switch is ON, the washer
motor operates but the wiper does not.
• The delayed finishing wipe function* has been
adopted to the windshield wiper. When the wiper
operation is stopped after spraying the washer
fluid, the wiper operates once to wipe out the
washer fluid ran down.
NOTE: *: Using the customise function, the vehicle
speed-dependent variable intermittent time function,
rain sensitive AUTO wiper function, washer-linked
wiper function and the delayed finishing wipe func-
tion can be selected (Refer to
P.51-20
).
DESCRIPTION OF CONSTRUCTION AND OPERATION
Intermittent control (Vehicle
speed-dependent variable type) <Initial
condition: with function>
1. ETACS calculates the windshield intermittent
wiper interval T1 from the position of the wind-
shield intermittent wiper switch on the column
switch and the vehicle speed signal (sent from
the combination meter to ETACS via CAN com-
munication).
NOTE: Using the customise function, the vehicle
speed-dependent variable intermittent time func-
tion can be invalidated (Refer to
P.51-20
).
2. When ETACS receives the ON signal of the wind-
shield intermittent wiper switch, it turns the wind-
shield wiper relay ON. When the wiper reaches
the stop position, the windshield wiper auto-stop
signal turns OFF, and the windshield wiper relay
turns OFF. When the intermittent time T1 calcu-
lated by step 1 has elapsed after the windshield
wiper relay ON, the windshield wiper relay turns
ON again, and the above-mentioned operation is
repeated.
