FRONT WIPER AND WASHER SYSTEM
System DiagramINFOID:0000000001366592
System DescriptionINFOID:0000000001366593
OUTLINE
The front wiper is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
 Front wiper control function
Control by IPDM E/R
 Front wiper control function
 Relay control function
FRONT WIPER BASIC OPERATION
 BCM detects the combination switch condition by the combination switch reading function.
 BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
 IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.
FRONT WIPER LO OPERATION
 BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
front wiper LO operating condition.
Front wiper LO operating condition
- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
 IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
 BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the
front wiper HI operating condition.
Front wiper HI operating condition
- Ignition switch ON
- Front wiper switch HI
 IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper
request signal (HI).

 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 OPERATION (IF EQUIPPED)
 BCM receives the wiping speed request signal from the rain sensor with the light and rain sensor serial link.
 BCM judges the auto wiping condition depending on the wiping speed request signal and the rain sensor
sensitivity setting under front wiper AUTO operating condition.
 BCM transmits the front wiper request signals (LO or HI) to the IPDM E/R through CAN communication line
according to the auto wiping condition.
NOTE:
When the wiper volume is turned down at 1 level with front wiper AUTO operating condition, BCM transmits
front wiper request signal (LO) to IPDM E/R with CAN communication.
Front wiper AUTO operating condition- Ignition switch ON
- Front wiper switch AUTO
Rain sensor sensitivity setting- BCM determines rain sensor sensitivity according to a wiper volume.

< 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".

REAR WIPER AND WASHER SYSTEM
 BCM reads an auto stop signal from the rear wiper motor to detect a rear wiper motor position.
 When the rear wiper motor is at other than the stopping position, BCM continues to supply power to the rear
wiper motor until it returns to the stopping position.
NOTE:
BCM stops supplying power to the rear wiper motor when the ignition switch is turned OFF.
REAR WIPER OPERATION LINKED WITH WASHER
 BCM supplies power to the rear wiper motor according to the washer linked operating condition of rear
wiper. When the rear washer switch is turned OFF, BCM controls rear wiper to operate approximately three
times.
Washer linked operating condition of rear wiper- Ignition switch ON
- Rear washer switch ON (0.4 second or more)
 Washer pump becomes grounded through the combination switch when the rear washer switch is turned
ON.
REAR WIPER DROP WIPE OPERATION
 BCM controls the rear wiper to operate once according to the rear wiper drop wipe operating condition.
Rear wiper drop wipe operating condition
- Ignition switch ON
- Rear wiper switch OFF
- Rear washer switch OFF
 BCM controls the rear wiper so that it operates once time approximately three seconds later after the washer
interlocking operation of the rear wiper.
