• BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication according to the
front wiper INT operation condition and the intermittent operation delay interval judged value.
Front wiper INT operating condition
- Ignition switch ON
- Front wiper switch INT
Intermittent operation delay interval judgment
- BCM calculates the intermittent operation delay interval from the vehicle speed signal received from the
wiper dial position and the combination meter with CAN communication.
• IPDM E/R turns the integrated front wiper relay ON so that the front wiper is operated only once according to
the front wiper request signal (INT).
• BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop
position signal received from IPDM E/R with CAN communication.
• BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval after
the front wiper motor is stopped.
FRONT WIPER AUTO STOP OPERATION
• BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
• IPDM E/R detects the front wiper auto stop signal from the front wiper motor and detects the front wiper
motor position (stop position/except stop position).
