Circuit Description

All functions of the front wiper and washer circuit are controlled by the position of the front wiper and washer switch in the multifunction switch and by the ETACM. The wiper switch has 4 positions : OFF, INT, LO and HI.

Wiper Operation

1. LO and HI position

When the wiper switch is in LO or HI, battery voltage is supplied to the front wiper motor directly and grounded through G07.

2. INT position

When the wiper switch is in INT and ignition switch is in ON, the wiper relay coil is energized through ETACM. Battery voltage applied to the front wiper motor and the front wiper motor is grounded at G05 through closed contact of the wiper relay.

3. OFF position

When the wiper switch is OFF and the front wiper motor is not in rest position, the front wiper motor is grounded at G01(Except Diesel)/G21(Diesel) through auto parking switch in the front wiper motor and the front wiper goes to the reset position.

Washer Operation

The front wiper motor operates as long as the washer switch is on. When the washer switch is pulled, the front wiper(controlled by the ETACM) wipes the window serveral times after the washer fluid sprays on to the front window.
