FRONT WIPER AND WASHER SYSTEM
Revision: November 20092006 QX56
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00BDS
System DescriptionEKS00BDT

Both front wiper relays are located in the IPDM E/R (intelligent power distribution module engine room).

The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input ter-
minals. Terminal combination status is read by the BCM when the wiper switch is turned ON.

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

IPDM E/R (intelligent power distribution module engine room) operates the wiper motor according to CAN
communication signals from the BCM.
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

through 30A fuse (No. 39, located in the IPDM E/R)

to front wiper relay (located in the IPDM E/R).
With the ignition switch in ON or START position, power is supplied

through 10A fuse (No. 9, located in the fuse block J/B)

to combination switch terminal 14, and

through 10A fuse (No. 59 located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied
