to CPU (located in IPDM E/R),

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 38,

through 15A fuse [No. 4, located in fuse block (J/B)]

to combination switch terminal 14.
Ground is supplied

to IPDM E/R terminals 39 and 59 and

to front wiper motor terminal 2

through grounds E15 and E24,

to BCM terminal 67

to combination switch terminal 12

through grounds M57 and M61.
LOW SPEED WIPER OPERATION
When the front wiper switch is in LO position, the BCM detects the low speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (LO) through the CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay, located in IPDM E/
R, power is supplied

through IPDM E/R terminal 33 and front wiper high relay and front wiper relay

to front wiper motor terminal 3.
Ground is supplied

to front wiper motor terminal 2

through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in HI position, the BCM detects a high speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (HI) through the CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay and front wiper high
relay, located in IPDM E/R, power is supplied

through IPDM E/R terminal 32

to front wiper motor terminal 5.
Ground is supplied

to front wiper motor terminal 2

through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the intermittent wiper dial position inputs. During
each intermittent operation delay interval, the BCM sends a front wiper request signal to the IPDM E/R to
operate the wipers.
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the intermittent
position, the BCM detects a front wiper (intermittent) ON signal by means of the BCM wiper switch reading
function.
BCM then sends front wiper (intermittent) request signal through the CAN communication lines

WW-6
FRONT WIPER AND WASHER SYSTEM
Revision: June 20062007 Versa

from BCM terminals 39 and 40

to IPDM E/R terminals 40 and 41.
When BCM determines that combination switch status is front wiper intermittent ON, it performs the following
operations.

BCM detects ON/OFF status of intermittent wiper dial position

BCM calculates operation interval from wiper dial position.

BCM sends a front wiper request signal (INT) to IPDM E/R at calculated operation interval.
When IPDM E/R receives the front wiper request signal (INT), it supplies ground to energize the front wiper
relay. It then sends auto-stop signal to the BCM and conducts intermittent front wiper motor operation.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When the wiper arms are not located at base of windshield with wiper switch OFF, ground is supplied

from IPDM E/R terminal 33

to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When the wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected, and
ground is supplied

to IPDM E/R terminal 38

through front wiper motor terminals 4 and 2

through grounds E15 and E24.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN com-
munication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When the wiper switch is in front wiper washer position, BCM detect front wiper washer signal by BCM wiper
switch reading function. Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" .
Combination switch power is supplied

through combination switch terminal 14

to washer motor terminal 1.
Ground is supplied

to front washer motor terminal 2

through combination switch terminal 11

through combination switch terminal 12

through grounds M57 and M61.
With ground is supplied, front washer motor is operated.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM operates front
wiper motor for low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.
MIST OPERATION
When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.
For additional information about wiper operation under this condition, refer to WW-5, "
LOW SPEED WIPER
OPERATION" .
If switch is held in mist position, low speed operation continues.
FAIL -S AFE F UN CTI ON
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned OFF. (If wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF.)
COMBINATION SWITCH READING FUNCTION
Refer to LT- 6 8 , "Combination Switch Reading Function" .

Times, They Become Inoperative)
EKS00I1U
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROT” item
shows “BLOCK”.
