System DescriptionNKS00520

All front wiper relays (HI, LO) are included in IPDM E/R (intelligent power distribution module engine
room).

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R operates wiper motor according to CAN communication signals from BCM.

to front washer pump terminal 2.
Ground is supplied

to BCM terminal 52

through grounds M30 and M66,

to IPDM E/R terminals 38 and 60

through grounds E17, E43 and B102 (with VDC system, navigation system or telephone),

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),

to combination switch terminal 12

through grounds M30 and M66.
LOW SPEED WIPER OPERATION
When the front wiper switch is in low position, BCM detects low speed wiper ON signal by BCM wiper switch
reading function.
BCM sends front wiper request signal (LOW) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When the IPDM E/R receives front wiper request signal (LOW), it turns ON front wiper relay, located in the
IPDM E/R, power is supplied

to front wiper motor terminal 3

through IPDM E/R terminal 21 and front wiper high relay and front wiper relay.
Ground is supplied

to front wiper motor terminal 4

through grounds E17, E43 and B102 (with VDC system, navigation system or telephone),

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone).
With power and ground is supplied, front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in high position, BCM detects high speed wiper ON signal by BCM wiper switch
reading function.
BCM sends front wiper request signal (HI) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay, located in IPDM E/
R, power is supplied

to front wiper motor terminal 2

through IPDM E/R terminal 31 and front wiper high relay and front wiper relay.
Ground is supplied

to front wiper motor terminal 4

through grounds E17, E43 and B102 (with VDC system, navigation system or telephone),

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone).
With power and ground is supplied, front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
After each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
