When the windshield wiper switch is in the position with the ignition switched ON (engine off or on), the start stop unit detects windshield wiper switch signal. 2. When the start stop unit detects the windshield wiper switch signal, the windshield wiper operation request signal is sent to the by CAN communication. 3. When the receives the windshield wiper operation request signal, it turns transistor A on (4). 4. When transistor A turns on, a ground circuit with the wiper INT relay is established (5), and the wiper INT relay turns on. 5. When the wiper INT relay turns on, the windshield wipers operate continuously at low speed.

When the windshield wiper switch is in the position with the ignition switched ON (engine off or on), the start stop unit detects windshield wiper switch and signals. 2. When the start stop unit detects the windshield wiper switch and signals, the windshield wiper operation request signal is sent to the by CAN communication. 3. When the receives the windshield wiper operation request signal, it turns transistors A and B on (4). 4. When transistors A and B turn on, a ground circuits with the wiper INT relay and the wiper relay are established (5), and the wiper INT relay and wiper relay turn on. 5. When the wiper INT relay and wiper relay turn on, the windshield wipers operate continuously at high speed.

Windshield wipers stopped in park position: Off Windshield wipers stopped in position other than park: On 1. When the windshield wiper switch is switched to the position during the windshield wiper operation, the turns transistor A off. 2. When transistor A is turned off, current flows to the auto stop switch which is on. 3. The windshield wipers operate to the park position by sending current to the auto stop switch. 4. When the windshield wipers return to the park position, the auto stop switch turns off (4).

When the windshield wiper switch is in the IST position with the ignition switched ON (engine off or on), the start stop unit detects windshield wiper switch signal. 2. When the start stop unit detects the windshield wiper switch signal, the windshield wiper operation request signal is sent to the by CAN communication. 3. When the receives the windshield wiper operation request signal, it turns transistor A on (4). 4. When transistor A turns on, a ground circuit with the wiper INT relay is established (5), and the wiper INT relay turns on. 5. When the wiper INT relay turns on, the windshield wipers operate at low speed.

When the windshield wiper switch is in the INT position with the ignition switched ON (engine off or on), the start stop unit detects windshield wiper switch INT signal. 2. When the start stop unit detects the windshield wiper switch INT signal, the windshield wiper INT operation request signal and the INT volume signal are sent to the by CAN communication. 3. When the receives the windshield wiper INT operation request signal, it turns transistor A on (4). 4. When transistor A turns on, a ground circuit with the wiper INT relay is established (5), and the wiper INT relay turns on. 5. When the wiper INT relay turns on, the windshield wipers operate continuously at low speed. 6. When the windshield wipers stop at the park position due to the auto stop operation and after a certain period of time has elapsed, which was calculated based on the INT volume signal, the operates the windshield wipers at a low speed (8). By repeating this, the windshield wipers operate intermittently.

(See WIPER SYSTE.) Synchronized washer operation 1. If the windshield washer switch is turned on with the ignition switched ON (engine off or on) and the windshield wipers not operating, the start stop unit detects a windshield washer switch on signal. 2. The start stop unit sends the windshield washer switch on signal to the via CAN communication. 3. When the receives the windshield washer switch on signal, it sends (4) the windshield washer operation request signal to the electrical supply unit (ESU) via LIN communication. 4. When the electrical supply unit (ESU) receives the windshield washer operation request signal, the washer motor is driven (5) and washer fluid is sprayed from the windshield washer nozzles. 5. When the receives the windshield washer switch on signal for a certain period of time, it operates the windshield wipers at low speed. 6. After the windshield washer switch is turned off (8), the windshield wipers operate 2 times at low speed and stop. Note If the windshield washer switch is turned on while the windshield wipers are operating, windshield wiper operation is continued and the windshield washer operation from to (5) is performed.
