PRECAUTION
1.

PRECAUTION FOR WASHER NOZZLE (for 4 Way
Type) HANDLING
(a) Do not adjust the washer nozzle with a safety pin,
etc. as the washer nozzle tip is made of resin and
could be damaged. Be sure to use SST for
adjustment.
SST 95060-10010
(b) When the washer nozzle is clogged with wax, etc.,
do not use metal objects such as a safety pin to
clean the washer nozzle hole. Be sure to use a soft
resin brush, etc.
NOTICE:
For Initialization:
When disconnecting the cable from the negative
(-) battery terminal, initialize the following
systems after the cable is reconnected.

System Name

See page

Power Window Control System

Initialization WS-7

NOTICE:
• When the warning light is illuminated or the
battery has been disconnected and
reconnected, pressing the power switch may
not start the system on the first try. If so,
press the power switch again.
• With the power switch's power mode
changed to ON (IG), disconnect the battery. If
the key is not in the key slot during
reconnection, DTC B2799 may be output.

SYSTEM DESCRIPTION
1.

2.

WW

WASHER LINKED OPERATION
(a) This system operates the front wipers at low speed
immediately after a jet of washer fluid when the front
washer switch is turned on for 0.3 seconds or more.
The system operates the front wipers at low speed
for approximately 2.2 seconds and then stops
operation when the washer switch is turned on for
1.5 seconds or more.
INTERMITTENT OPERATION
(a) The system operates the front wipers once in
approximately 1.6 to 10.7 seconds when the front
wiper switch is turned to the INT position. The
intermittent time can be adjusted from 1.6 to 10.7
seconds by using the intermittent time adjust dial.

WIPER AND WASHER – WIPER AND WASHER SYSTEM

WW–7

(b) If the wiper control switch is turned to the INT
position, current flows from the already charged
capacitor C1 through terminals INT1 and INT2 of
the wiper control switch, to Tr1 (transistor). When
Tr1 turns on, current flows from terminal +S of the
wiper control switch to terminal +1 of the wiper
control switch, to terminal +1 of the wiper motor, to
the wiper motor and finally to ground, causing the
wiper motor to operate. At the same time, current
flows from capacitor C1 to terminal INT1 of the
wiper control switch and then INT2. When the
current flow from capacitor C1 ends, Tr1 turns off to
stop the relay contact point and halt the wiper motor.
When the relay contact point turns off, capacitor C1
begins to charge again and Tr1 remains off until
charging has been completed. This period
corresponds to the intermittent time. When
capacitor C1 is fully charged, Tr1 turns on and then
the relay contact point turns on, causing the motor
to operate again. This cycle is the intermittent
operation.
The intermittent time can be adjusted by using the
intermittent time adjust dial (variable resistor) to
change the charge time of capacitor C1.

REAR WIPER INTERMITTENT OPERATION
(a) When the rear wiper control switch is turned to the
INT position, current flows from the capacitor of the
intermittent operation control circuit to turn on Tr.
Current flows from terminal +B of the rear wiper
relay, to relay coil, to Tr, to terminal C1 of the rear
wiper relay, to terminal C1R of the rear wiper control
switch and finally to ground, causing the relay
contact point to turn on.
When the relay contact point turns on, current flows
from terminal +B of the rear wiper relay to the relay
contact point, to terminal LM of the rear wiper relay,
to terminal +1 of the rear wiper motor, to the rear
wiper motor and finally to ground, causing the rear
wiper motor to operate.
Tr turns off immediately after the rear wiper motor
operation as the current flow from capacitor ends,
causing the relay contact point to turn off.
Even when the relay contact point turns off, current
flows from terminal +B of the rear wiper motor, to
the relay contact point in the rear wiper motor, to
terminal S of the rear wiper motor, to terminal SM of
the rear wiper relay, to the contact point of the rear
wiper relay, to terminal LM of the rear wiper motor,
to terminal +1 of the rear wiper motor and finally to
ground until the rear wiper motor stops at the
automatic stop position, causing the rear wiper
motor to operate. Then the rear wiper motor stops at
the automatic stop position as the relay contact
point in the rear wiper motor turns off.
The capacitor in the intermittent operation control
circuit is charged in approximately 12 seconds after
the current flow ends. After the charge is completed,
current starts flowing again to turn on Tr, causing
the relay contact point to turn on.
This cycle (of current flow and charging) as
described above is the intermittent operation.
