< FUNCTION DIAGNOSIS >
FRONT WIPER AND WASHER SYSTEM
 IPDM E/R turns ON the integrated front wiper relay and front wiper HI relay according to the front wiper
request signal (LO or HI).
 Light and rain sensor transmits rain sensor signal to BCM for HI operation immediately after sensing the
raindrops increase under the wiper motor LO operating with the front wiper switch AUTO.
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).
 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 and rear 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 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.
