FRONT WIPER AND WASHER SYSTEM
Revision: 2006 December 2006 FX35/FX45
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS00326
System DescriptionNKS00327

All front wiper relays (HI, LO) are included in IPDM E/R (intelligent power distribution module engine
room).

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R operates wiper motor according to CAN communication signals from BCM.
OUT LINE
Power is supplied at all times

through 50 A fusible link (letter M, located in fuse, fusible link and relay box.)

to BCM terminal 55,

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42,

through 30 A fuse (No. 73, located in IPDM E/R)

to front wiper relay, located in IPDM E/R,

through 15 A fuse (No. 78, located in IPDM E/R) and

through 10 A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
When the ignition switch is ON or START position, power is supplied

to ignition relay located in IPDM E/R, from battery direct,

through 15 A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through ignition relay, located in IPDM E/R

FRONT WIPER AND WASHER SYSTEM
Revision: 2006 December 2006 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 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 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" .

If switch is held in MIST position, low speed operation continues.
FAIL-SAFE FUNCTION
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.)

CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-II. Refer to LT- 11 9 , "
