FRONT WIPER AND WASHER SYSTEM

Components Parts and Harness Connector LocationBKS001TF
System DescriptionBKS001TG
BCM (Body Control Module) controls front wiper low, high and intermittent operation.
IPDM E/R (Intelligent Power Distribution Module Engine Room) operates front wiper motor according to
CAN communication signals from BCM.
Power is supplied at all times
to ignition relay (located in IPDM E/R), from battery direct,
through 50 A fusible link (letter M, located in fuse and fusible link block)
to BCM terminal 55,
through 15 A fuse [No. 17, located in fuse block (J/B)]
to BCM terminal 42,
through 20 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)
to CPU (central processing unit) located in IPDM E/R,
through 15 A fuse (No. 71, located in IPDM E/R)
to CPU located in IPDM E/R.
When the ignition switch ON or START position, power is supplied
to ignition relay (located in IPDM E/R),
through 10 A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38,

through 10 A fuse (No. 84, located in IPDM E/R)
to front washer pump terminal 1.
Ground is supplied
to BCM terminal 52 and
to combination switch terminal 12
through grounds M71 and M72,
to IPDM E/R terminals 38 and 60
through grounds E1 and E31.
LOW SPEED WIPER OPERATION
When the front wiper switch is in LO position, BCM detects the FR WIPER LOW (ON) by BCM combination
switch reading function. BCM sends front wiper request signal (LO) through CAN communication.
When receiving front wiper request signal (LO), IPDM E/R turns ON front wiper relay in IPDM E/R. IPDM E/R
supplies power
through IPDM E/R terminal 21, front wiper high relay and front wiper relay
to front wiper motor terminal 1.
Ground is supplied
to front wiper motor terminal 2
through grounds E1 and E31.
With power and ground is supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in HI position, BCM detects the FR WIPER HI (HI) by BCM combination switch
reading function. BCM sends front wiper request signal (HI) through CAN communication.
When receiving front wiper request signal (HI), IPDM E/R turns ON front wiper relay and front wiper high relay
in IPDM E/R. IPDM E/R supplies power
through IPDM E/R terminal 31, front wiper high relay and front wiper relay
to front wiper motor terminal 4.
Ground is supplied
to front wiper motor terminal 2
through grounds E1 and E31.
With power and ground is supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation is determined from a combination of 3 switches (INT VOLUME 1, 2, and 3)
and vehicle speed signal*.
When the front wiper switch is in INT position, BCM detects the FR WIPER INT (ON) and ON/OFF status of
the INT VOLUME 1, 2, and 3 by BCM combination switch reading function. BCM judges the condition of wiper
intermittent dial position by ON/OFF status of INT VOLUME 1, 2, and 3 .
BCM sends front wiper request signal (1LOW) at certain intervals through CAN communication. The interval is
calculated by wiper intermittent dial position and vehicle speed signal received from combination meter
through CAN communication.
When receiving front wiper request signal (1LOW), IPDM E/R turns ON front wiper relay in IPDM E/R, and
operates front wiper motor at low speed. Then IPDM E/R detects front wiper arms reach to the stop position
via wiper auto stop signal from front wiper motor, IPDM E/R turns OFF front wiper relay, and sends front wiper
auto stop signal (ON) to BCM through CAN communication, and controls intermittent operation.

FRONT WIPER AND WASHER SYSTEM
Wiper Intermittent 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 interval from wiper intermittent dial position 1 and vehicle
speed, and sends wiper request signal (INT) to IPDM E/R.
AUTO STOP OPERATION
With the front wiper switch turned OFF, front wiper motor will continue to operate until front wiper arms reach
windshield base.
When front wiper arms are not located at base of windshield with front wiper switch OFF, power is provided
from IPDM E/R terminal 21
to front wiper motor terminal 1, in order to continue front wiper motor operation at low speed.
When front wiper arms reach base of windshield, front wiper motor terminals 2 and 5 are connected, and
ground is supplied
to IPDM E/R terminal 32
through front wiper motor terminal 5
through front wiper motor terminal 2
through grounds E1 and E31.
Then the IPDM E/R sends front wiper auto stop signal (ON) to BCM through CAN communication.
When the BCM receives front wiper auto stop signal (ON), BCM sends front wiper request signal (OFF) to
IPDM E/R through CAN communication.
IPDM E/R stops front wiper motor. Front wiper motor will then stop front wiper arms at the STOP position.
WASHER OPERATION
When the front washer switch is ON position, front washer pump operates, and BCM detects the FR WASHER
(ON) by BCM combination switch reading function. Combination switch ground is supplied
to front washer pump terminal 2
through combination switch terminal 11
to combination switch terminal 12
through grounds M71 and M72.
When BCM detects the FR WASHER (ON) for 0.4 seconds or longer, BCM sends front wiper request signal
(LO) through CAN communication. IPDM E/R operates front wiper motor at low speed.
When BCM detects the front washer switch is OFF, low speed wiper operation cycles approximately 2 times
and stops.

MIST OPERATION
When the front wiper switch is turned to the MIST position, front wiper low speed operation cycles once and
then stops.
For additional information about front wiper operation under this condition. Refer to WW-5, "
LOW SPEED
WIPER OPERATION" .
If the switch is held in the 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 front 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
Description
BCM reads combination switch (wiper switch) status, and controls front wipers according to the results.
BCM reads information of a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).
Operation Description
BCM activates transistors of output terminals (OUTPUT 1-5) periodically and allows current to flow in turn.
If any (one or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.
At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that the switch is ON.
