FRONT WIPER AND WASHER SYSTEM
Revision: 2007 April2007 M35/M45
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS003WB
System DescriptionNKS003WC

Front wiper relays (HIGH, LOW) are included in IPDM E/R (intelligent power distribution module engine
room).

Front wiper reverse relay is included in relay box-1. Refer to PG-98, "ELECTRICAL UNITS LOCATION" .

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.

Front wiper motor switches LOW speed to/from HIGH speed by BCM function to change polarity.
OUTLINE
Power is supplied at all times

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

through 50 A fusible link (letter F, located in fuse and fusible link block)

to BCM terminal 55,

through 10 A fuse [No. 21, located in fuse block (J/B)]

to BCM terminal 42,

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

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

to front wiper reverse relay terminal 5,

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

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

to BCM terminal 38,

through 10 A fuse [No. 12, located in fuse block (J/B)]

to front wiper motor terminal 4.
Ground is supplied

to BCM terminal 52

through grounds M16 and M70,

to IPDM E/R terminals 38 and 51

through grounds E22 and E43,

to combination switch terminal 12

through grounds M16 and M70.
LOW SPEED WIPER OPERATION
When wiper switch is in the LO position, BCM detects low speed wiper ON signal by BCM wiper switch read-
ing function.
BCM sends front wiper request signal (LO) 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 (LO), it turns ON front wiper low relay, located in IPDM
E/R, power is supplied

through IPDM E/R terminal 23 and front wiper high relay and front wiper low relay

to front wiper motor terminal 3.
Ground is supplied

to front wiper motor terminal 1

through front wiper reverse relay terminals 3 and 4

through grounds E22 and E43.
With power and ground supplied, the front wiper motor operates at low speed.
