Windshield Wiper Motor
The windshield wiper motor is controlled by the MICU. Auto-stop contacts are provided in each motor, and the motor stop position is feed back to the MICU. When the motor temperature becomes high because of an overload etc., the motor is stopped temporarily by its circuit breaker, interrupting the circuit.
Rear Window Wiper Motor
The rear window wiper motor is controlled by the MICU. Auto-stop contacts are provided in each motor, and the motor stop position is feed back to the MICU. When the motor temperature becomes high because of an overload etc., the motor is stopped temporarily by its circuit breaker, interrupting the circuit.
Wiper/Washer Switch
The wiper/washer switch is installed on the steering column. The wiper/washer switch inputs the switch status to the MICU.
Washer Motor
