• to front wiper motor terminal 2
• through grounds E15 and E24
• to BCM terminal 67, and
• to combination switch (wiper switch) terminal 12
• through grounds M57 and M61.
LOW SPEED WIPER OPERATION
When the front combination switch (wiper switch) is in LO position, the BCM detects the low speed wiper ON
signal by means of the BCM combination switch (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 combination switch (wiper switch) is in HI position, the BCM detects a high speed wiper ON
signal by means of the BCM combination switch (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 s ends a front wiper request signal to the IPDM E/R to
operate the wipers.
When the ignition switch is in the ON or START positi on, and the front combination switch (wiper switch) is
turned to the intermittent position, the BCM detects a fr ont wiper (intermittent) ON signal by means of the BCM
combination switch (wiper switch) reading function.
BCM then sends front wiper (intermittent) request signal through the CAN communication lines
• from BCM terminals 39 and 40
• to IPDM E/R terminals 40 and 41.
When BCM determines that combination switch (wiper swit ch) 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 combination switch (wiper switch) turned OFF, wi per motor will continue to operate until wiper arms reach
windshield base.
When the wiper arms are not located at base of windshield with combination switch (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, and
• 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 wi ll then stop wiper arms at the STOP position.
WASHER OPERATION
When the combination switch (wiper switch) is in front wiper washer position, BCM detect front wiper washer
signal by BCM combination switch (wiper switch) reading function. Refer to BCS-4, "
System Description" .
Combination switch (wiper switch) power is supplied
• through combination switch (wiper switch) terminal 14
• to washer motor terminal 1.
Ground is supplied
• to front washer motor terminal 2
• through combination switch (wiper switch) terminal 11, and
• through combination switch (wiper switch) terminal 12
• through grounds M57 and M61.
With ground 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 combination switch (wiper switch) is turned to the mist position, wiper low speed operation cycles
once and then stops.
For additional information about wiper operation under th is condition, refer to "LOW SPEED WIPER OPERA-
TION" .
If switch is held in mist posit ion, 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 we re operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF.)
