to front wiper high relay, located in IPDM E/R and
to CPU located in IPDM E/R,
through 10 A fuse (No. 84, located in IPDM E/R)
through IPDM E/R terminal 44
to combination switch terminal 14.
Ground is supplied
to BCM terminals 49 and 52
through grounds M35, M45 and M85,
to IPDM E/R terminals 38 and 60
through grounds E21, E50 and E51,
to combination switch terminal 12
through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When wiper switch is in LOW position, BCM detects low speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (LO) through CAN communication
from BCM terminals 39 and 40
to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay located in IPDM E/R,
power is supplied
through front wiper relay
through front wiper high relay
through IPDM E/R terminal 21
to front wiper motor terminal 1.
Ground is supplied
to front wiper motor terminal 2
through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (HI) through CAN communication
from BCM terminals 39 and 40
to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied
through front wiper relay
through front wiper high relay
through IPDM E/R terminal 31
to front wiper motor terminal 4.
Ground is supplied
to front wiper motor terminal 2
through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
Speed dependent wiper controlled mode can be changed by the function setting of CONSULT-ll or display.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

FRONT WIPER AND WASHER SYSTEM
Revision: 2006 July 2007 FX35/FX45
Wiper Dial Position Setting
Example: For wiper intermittent dial position 1
Using combination switch reading function, BCM detects ON/OFF status of INT VOLUME 1, 2, and 3.
When combination switch status is as listed below, BCM determines that it is wiper intermittent dial position 1.
INT VOLUME 1: ON (Continuity exists between combination switch output 3 and input 1.)
INT VOLUME 2: ON (Continuity exists between combination switch output 5 and input 1.)
INT VOLUME 3: ON (Continuity exists between combination switch output 4 and input 2.)
BCM determines front wiper intermittent operation delay interval from wiper intermittent dial position 1 and
vehicle speed, and sends wiper request signal (INT) to IPDM E/R.
AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided
from IPDM E/R terminal 21
to front wiper motor terminal 1, in order to continue wiper motor operation at low speed.
When wiper arms reach base of windshield, front wiper motor terminals 5 and 2 are connected,
and Ground is supplied
to IPDM E/R terminal 32
through front wiper motor terminals 5 and 2
through grounds E21, E50 and E51.
Then the IPDM E/R sends auto stop operation signal to BCM through CAN communication.
When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R through CAN
communication.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WASHER OPERATION
When wiper switch is in front wiper washer position with ignition switch on, BCM detects front wiper switch is
on the washer position by BCM wiper switch reading function (Refer to WW-8, "
COMBINATION SWITCH
READING FUNCTION" ), combination switch (wiper switch) ground is supplied
to combination switch terminal 13
through front and rear washer pump terminal 1
to front and rear washer pump terminal 2
through combination switch terminal 11
to combination switch terminal 12
through grounds M35, M45 and M85.
With ground supplied, front and rear washer pump is operated.
When BCM detects that front and rear washer pump has operated for 0.4 seconds or linger, BCM operates
front wiper motor for low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.
MIST OPERATION
When wiper switch is turned to 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" .
