FRONT WIPER AND WASHER SYSTEM
PFP:28810
Components Parts and Harness Connector LocationEKS00P4U
System DescriptionEKS00P4V
lAll front wiper relays (MAIN, LOW/HIGH) are located in IPDM E/R (intelligent power distribution module
engine room).
lWiper 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 the wiper switch is turned
ON.
lBCM controls front wiper LO, HI, and INT (intermittent) operation.
lIPDM E/R operates the wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times
lto ignition relay (located in IPDM E/R), from battery directly,
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57,
lthrough 30A fuse (No. 39, located in IPDM E/R)
lto front wiper main relay (located in IPDM E/R).

HEADLAMP WASHER OPERATION
With the headlamp washer switch in the ON position, the BCM receives input signal requesting. This input sig-
nal is communicated to the IPDM E/R via the CAN communication. The CPU located in the IPDM E/R controls
the headlamp washer relay coil, which when energized, power is supplied
lthrough 10A fuse (No. 38, located in IPDM E/R)
lthrough IPDM E/R terminal 27
lto headlamp washer relay terminals 2 and 5,
lthrough headlamp washer relay terminal 1
lto IPDM E/R terminal 5,
lthrough headlamp washer relay terminal 3
lto headlamp washer motor terminal 1.
Ground is supplied
lto headlamp washer motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, headlamp washer operates.
