When ignition switch ON or START position, power is supplied
through10Afuse[No.5,locatedinfuseblock(J/B)]
to BCM terminal 24,
through10Afuse[No.3,locatedinfuseblock(J/B)]
to combination switch terminal 14, and
to front wiper HI/LO relay, front wiper main relay and IPDM E/R (CPU)
Ground is supplied
to front wiper motor terminal 2 and,
to IPDM E/R terminals 3 and 54
through body grounds E28, E44 and E45, and
to combination switch terminal 12 and
to BCM terminals 2 and 70
through body grounds M21 and M66.
LOW SPEED WIPER OPERATION
When front wiper switch is placed in LO position, BCM reads combination switch condition (Refer to WW-8,
"COMBINATION SWITCH READING FUNCTION" ). And BCM sends front wiper request signal (LO) to IPDM
E/R with CAN communication line. When IPDM E/R receives front wiper request signal (LO), it turns ON front
wiper main relay (built into IPDM E/R).
Power is supplied
through front wiper main relay and front wiper HI/LO relay and
through IPDM E/R terminal 23
to front wiper motor terminal 1.
Ground is supplied
to front wiper motor terminal 2,
through body grounds E28, E44 and E45.
With power and ground are supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When front wiper switch is placed in HI position, BCM reads combination switch condition (Refer toWW-8,
"COMBINATION SWITCH READING FUNCTION" ). And BCM sends front wiper request signal (HI) to IPDM
E/R with CAN communication line. When IPDM E/R receives front wiper request signal (HI), it turns ON front
wiper HI/LO relay and front wiper main relay (built into IPDM E/R).
Power is supplied
through front wiper main relay and front wiper HI/LO relay and,
through IPDM E/R terminal 24
to front wiper motor terminal 4.
Ground is supplied
to front wiper motor terminal 2
through body grounds E28, E44 and E45.
With power and ground are supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation delay interval is determined by a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and by vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
