• 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).

< FUNCTION DIAGNOSIS >
FRONT WIPER AND WASHER SYSTEM
• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper
motor returns to the stop position.
NOTE:
• BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.
• IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.
FRONT WIPER OPERATION LINKED WITH WASHER
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
washer linked operating condition of the front wiper.
• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 3 times
when the front washer switch OFF is detected.
Washer linked operating condition of front wiper
- Ignition switch ON
- Front washer switch ON (0.4 second or more)
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
• The front washer motor is grounded through the combination switch with the front washer switch ON.
FRONT WIPER DROP WIPE OPERATION
• BCM controls the front wiper to operate once according to the conditions of front wiper drop wipe operation.
Front wiper drop wipe operating condition
- Ignition switch ON
- Front wiper switch OFF
- Front washer switch OFF
• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication so that the front
wiper operate once three seconds after front wiper operation linked with washer.
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER FAIL
−
SAFE OPERATION
• IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to

Part
Description
BCM
• Judges each switch status by the combination switch reading function.
• Requests (with CAN communication) the front wiper relay and the front wiper high relay ON to
IPDM E/R.
IPDM E/R
• Controls the integrated relay according to the request (with CAN communication) from BCM.
• Performs the auto stop control of the front wiper.
Combination switch
(Wiper and washer
switch)
.
Combination meter
Transmits the vehicle speed signal to BCM with CAN communication.
