FRONT WIPER AND WASHER SYSTEM
Revision: 2007 April2007 M35/M45
HIGH SPEED WIPER OPERATION
When wiper switch is in the HI position, BCM detects high speed wiper ON signal by BCM wiper switch read-
ing function.
BCM sends front wiper request signal (HI) with CAN communication line
from BCM terminals 39 and 40
to IPDM E/R terminals 49 and 50.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper high relay (located in IPDM
E/R) and front wiper reverse relay (located in relay box-1), power is supplied
through IPDM E/R terminal 19
through front wiper reverse relay terminals 5 and 3
to front wiper motor terminal 1.
Ground is supplied
to front wiper motor terminal 2
to IPDM E/R terminal 31 and front wiper high relay and front wiper low relay
to IPDM E/R terminal 38
through grounds E22 and E43.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
1. BCM detects ON/OFF status of intermittent operation dial position 1, 2 and 3 switched by wiper dial posi-
tion to judge wiper dial position status.
2. BCM calculates intermittent operation interval time (second) from the vehicle speed signal received by
combination meter through CAN communication line and the wiper dial position.
Unit: second
NOTE:
The value in the table can differ from the actual vehicle speed.
3. BCM switches front wiper request signal transmitted to IPDM E/R through CAN communication line from
STOP to LO once at intervals of intermittent operation time.
4. IPDM E/R receives front wiper request signal (LO) once to turn ON front wiper main relay located in IPDM
E/R. Then operates front wiper. IPDM E/R receives front wiper auto stop signal (stop) input from front
wiper motor to turn OFF front wiper motor relay. IPDM E/R switches front wiper auto stop signal transmit-
ted through CAN communication line from MOVE to STOP.
5. BCM receives front wiper auto stop signal (stop) to operate timer that determines intermittent operation
interval time till next front wiper motor operation.

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 23
to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When wiper arms reach base of windshield, front wiper motor terminals 4 and 5 are connected
to IPDM E/R terminal 32
through front wiper motor terminals 4 and 5.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When BCM receives auto stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN commu-
nication 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 washer
signal by BCM wiper switch reading function (refer to BCS-3, "
COMBINATION SWITCH READING FUNC-
TION" ). Combination switch ground is supplied
to front washer pump terminal 2
through combination switch terminal 14
to combination switch terminal 12
through grounds M16 and M70.
With power and ground supplied, front washer pump is operated.
When BCM detects that front washer pump has operated for 0.4 seconds or longer, 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 the wiper switch is turned to the 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 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 wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LOW until ignition switch is turned OFF.)
