- 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
WW-52, "
FailSafe".
 BCM performs fail-safe operation when light and rain sensor (if equipped) or light and rain sensor-related
systems are malfunctioning. Refer to EXL-55, "
Description".

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)Refer to WW-4, "
System Diagram".
Combination meter Transmits the vehicle speed signal to BCM with CAN communication.
Light and rain sensor (if
equipped)Detects water droplets on the windshield with infrared rays, and transmits the rain sensor signal
to BCM through the light and rain sensor serial link.
