## 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 windshield wiper switch is turned to the INT position, current flows to the windshield wiper motor due to a control signal from the microcomputer in the auto wiper control module, and the windshield wiper motor operates at low speed.

2. When a pre-set time has passed, current is stopped due to a control signal from the microcomputer in the auto wiper control module. Accordingly, current flow to the windshield wiper motor ceases, causing the wipers to stop at the park position due to the autostop operation. This sequence repeats causing the wipers to operate intermittently.

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.
