FRONT WIPER AND WASHER SYSTEM

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,

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

DISASSEMBLY
1. Remove wiper linkage from wiper motor and motor frame.
2. Remove wiper motor mounting bolts, and remove wiper motor from wiper frame.
CAUTION:
Be careful not to bend linkage and not to damage the resin part of ball joint when removing wiper link-
age.
ASSEMBLY
1. Connect wiper motor connector. Turn wiper switch ON to operate wiper motor, and then turn wiper switch
OFF (auto stop).
2. Disconnect wiper motor connector.
3. Install wiper motor to wiper frame.
4. Install wiper linkage to wiper frame and wiper motor.
CAUTION:

Never drop the wiper motor or cause it to contact other parts.

Check grease conditions of the motor arm and wiper linkage joint (at retainer). Apply grease if
necessary.
