CAN COMMUNICATION
System DescriptionINFOID:0000000001327578
CAN (Controller Area Network) is a serial communication li ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to LAN-43, "
CAN System Specification Chart".

FRONT WIPER AND WASHER SYSTEM
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 det ermines that it is wiper intermittent dial position 1.
 INT VOLUME 1: ON (Continuity exists bet ween combination switch output 3 and input 1.)
 INT VOLUME 2: ON (Continuity exists bet ween combination switch output 5 and input 1.)
 INT VOLUME 3: ON (Continuity exists bet ween combination switch output 4 and input 2.)
BCM determines front wiper intermittent operation delay in terval 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 conti nue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of winds hield 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, fr ont 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 operati on 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 wit h ignition switch on, BCM detects front wiper switch is
on the washer position by BCM wiper switch reading function (Refer to "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 s peed 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 "LOW SPEED WIPER OPERA-
TION".
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 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.)
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
CAN Communication System DescriptionINFOID:0000000001328544
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
