Front Wiper Hi Operation

• BCM transmits the front wiper request signal (HI) to IPDM E/R via CAN communication according to the front wiper HI operating condition.

Front wiper HI operating condition

• Ignition switch ON
• Front wiper switch HI

• When detecting that front wiper request signal changes from OFF to HI or from LO to HI, IPDM E/R performs LO operation (front wiper motor rotation is clockwise) until detecting front wiper position signal from front wiper motor is in near range of the upper or lower reversal position. When detecting the upper or lower reversal position, IPDM E/R turns front wiper main relay OFF, front wiper HI/LO relay ON, and wiper reverse relay ON. Front wiper motor operates counterclockwise at HI.
