Continuous Operation

1.  When the windshield wiper switch is turned to 1, current (1) flows, and the windshield wiper motor operates at low speed.

2.  When the windshield wiper switch is turned to 2, current (2) flows, and the windshield wiper motor operates at high speed.

3.  When the windshield wiper switch is turned to the OFF position, the wipers stop in the park position due to the autostop operation.

Autostop Operation

1.  When the windshield wiper switch is turned to the OFF position while the wipers are operating, current flows to the autostop switch, which is on, and the windshield wiper motor operates until it returns to the park position, stopping the wipers.

One-touch Wiper Operation

1.  When the windshield wiper lever is pulled up, the one-touch switch is on and the current flows, causing the windshield wiper motor to operate at low speed.

2.  The windshield wipers operate at low speed while the windshield wiper lever is pulled up. When the windshield wiper lever is released, the wipers stop in the park position due to the autostop operation.

Intermittent Wiper Operation

1.  When the wiper switch moves to the INT position, the intermittent wiper (INT) relay turns on, and current flows through the INT relay to the wiper switch, wiper motor, then to ground. The wipers operate at low speed.

2.  When the preset period of time has passed, the INT relay turns off. The current stops flowing through the wiper motor. The autostop function activates, and the wipers stop at the park position. Cycling through this sequence of operations, the wipers operate at specified intervals.

3.  The windshield wipers operation timing (INT relay OFF to ON) during intermittent operation can be set freely using the INT volume switch.

Synchronized Washer And Wiper Operation

1.  When the windshield washer switch is turned on, current (1) flows and the windshield washer motor operates, and washer fluid is sprayed. At the same time, a washer motor operation signal is sent to the INT relay causing the relay to turn on, current (2) to flow, and the windshield wiper motor to operate at low speed.
