Front Wiper Int Operation

• BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication depending on the front wiper INT operating condition and intermittent operation delay interval according to the wiper intermittent dial position.

Front wiper INT operating condition

• Ignition switch ON
• Front wiper switch INT
  • IPDM E/R turns ON the integrated front wiper relay 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.

    NOTE: Factory setting of the front wiper intermittent operation is the operation without vehicle speed. Front wiper intermittent operation can be set to the operation with vehicle speed by CONSULT-III. Refer to "WIPER : CONSULT-III FUNCTION (BCM - WIPER) ".

Front wiper intermittent operation with vehicle speed

• BCM calculates the intermittent operation delay interval from the following
  • Vehicle speed signal (received from the unified meter and A/C amp. with CAN communication)
  • Wiper intermittent dial position
