Operation<\/p>\n


<\/p>\n

<\/a><\/p>\n

Continuous wiper operation<\/p>\n

1.When the rear wiper and washer switch is in the on position (1), the instrument cluster detects (2) a rear wiper switch on signal.<\/p>\n

\n

2.The instrument cluster sends (3) the rear wiper switch on signal to the body control module (BCM) via CAN communication.<\/p>\n

\n

3.When the body control module (BCM) receives the rear wiper switch on signal, it sends (4) a rear wiper operation request signal to the electrical supply unit (ESU) via CAN communication.<\/p>\n

\n

4.When the electrical supply unit (ESU) receives the rear wiper operation request signal, it turns FET A on (5).<\/p>\n

\n

5.When FET A turns on, the rear wiper operates (6) continuously.<\/p>\n

<\/p>\n

<\/a><\/p>\n

Auto-stop operation<\/p>\n

\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The auto stop switch in the rear wiper motor operates as follows according to the operation position of the rear wiper.<\/div>\n
\n
\n
\u2015 Rear wiper in park position: Off<\/div>\n
\u2015 Rear wiper in position other than stop: On<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Operation conditions<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
\u2022 Rear wiper and washer switch turns off during continuous wiper operation<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Operation<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
1. When the rear wiper and washer switch is in the off position (1), the electrical supply unit (ESU) turns transistor A off (2).<\/div>\n
2. The rear wiper operates (3) continuously because the autostop switch is on.<\/div>\n
3. When the rear wiper stops at the park position, the autostop switch turns off (4).<\/div>\n
4. When the autostop switch turns off, the rear wiper stops (5).<\/p>\n\n\n\n

<\/p>\n

<\/a><\/p>\n

Intermittent wiper operation<\/p>\n

1.When the rear wiper and washer switch is in the INT position (1), the instrument cluster detects (2) a rear wiper switch INT signal.<\/p>\n

\n

2.The instrument cluster sends (3) the rear wiper switch INT signal to the body control module (BCM) via CAN communication.<\/p>\n

\n

3.When the body control module (BCM) receives the rear wiper switch INT signal, it sends (4) a rear wiper operation request signal to the electrical supply unit (ESU) via CAN communication.<\/p>\n

\n

4.When the electrical supply unit (ESU) receives the rear wiper operation request signal, it turns FET A on (5).<\/p>\n

\n

5.When FET A turns on, the rear wiper performs intermittent wiper operation (6).<\/p>\n

<\/p>\n

<\/a><\/p>\n

Synchronized washer operation<\/p>\n

1.When the rear wiper and washer switch is in the rear washer position (1) with the ignition switched ON (engine off or on), the instrument cluster detects (2) a rear washer switch on signal.<\/p>\n

\n

2.The instrument cluster sends (3) the rear washer switch on signal to the body control module (BCM) via CAN communication.<\/p>\n

\n

3.When the body control module (BCM) receives the rear washer switch on signal, it turns FET A and FET D on (4) and operates (5) the rear washer motor.<\/p>\n

\n

4.When the body control module (BCM) receives the rear washer switch on signal for a certain period of time, it sends (6) a rear wiper operation request signal to the electrical supply unit (ESU) via CAN communication.<\/p>\n

\n

5.When the electrical supply unit (ESU) receives the rear wiper operation request signal, it operates (7) the rear wiper.<\/p>\n

\n

6.When the rear washer switch is in the off position, the rear wiper stops after it operated twice.<\/p>\n
