Continuous Operation

1. When the rear wiper switch is turned to the ON position, control signal (1) is output from the microcomputer in the BCM, and the transistor is turned on.

2. When the transistor is on, current (2) flows to the rear wiper motor and continuous operation starts.

• When the rear wiper switch is turned to the OFF position while the rear wiper is operating, the rear wiper motor performs an auto stop and stops in the park position.

Auto Stop Operation

• When the rear wiper switch is turned to the OFF position while the wiper is operating, current flows to the auto stop switch, which is on, and the rear wiper motor operates until it returns to the park position, stopping the wiper.

Intermittent Wiper Operation

• When the rear wiper switch is turned to the INT position, the microcomputer in the BCM supplies current (1) at 10 s intervals to turn on the transistor intermittently.
• As a result, current (2) flows at 10 s intervals causing the rear wiper to operate intermittently.
• When the rear wiper switch is turned to the OFF position while the wiper is operating, the rear wiper motor performs an auto stop and stops in the park position.

Synchronized Washer And Wiper Operation

• When the rear wiper switch is turned upward from the ON position while the wiper is operating, current (2) flows, the rear washer motor operates and washer fluid is sprayed from the rear washer nozzle.

• While turning the rear wiper switch downward from the OFF position, current (2) flows, the rear washer motor operates and washer fluid is sprayed from the rear washer nozzle. Current (1) flows at the same time according to the control signal from the microcomputer and the rear wiper motor operates continuously.
