FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS00326
System DescriptionNKS00327

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.
OUT LINE
Power is supplied at all times

through 50 A fusible link (letter M, located in fuse, fusible link and relay box.)

to BCM terminal 55,

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM terminal 42,

through 30 A fuse (No. 73, located in IPDM E/R)

to front wiper relay, located in IPDM E/R,

through 15 A fuse (No. 78, located in IPDM E/R) and

through 10 A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
When the ignition switch is ON or START position, power is supplied

to ignition relay located in IPDM E/R, from battery direct,

through 15 A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through ignition relay, located in IPDM E/R

to CPU located in IPDM E/R,

through 10 A fuse (No. 84, located in IPDM E/R)

through IPDM E/R terminal 44

to combination switch terminal 14.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85,

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51,

to combination switch terminal 12

through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When 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 (LO) with CAN communication line

from BCM terminals 39 and 40

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

to front wiper motor terminal 1

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

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When wiper switch is in HI 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 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 4

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

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the 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.
Speed dependent wiper controlled mode can be changed by the function setting of CONSULT-ll or display.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.
