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).

With the ignition switch in ON or START position, power is supplied
lthrough 10A fuse [No. 15, located in fuse block (J/B)]
lto combination switch terminal 2,
lthrough 10A fuse [No. 1, located in fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55 and
lto combination switch terminal 9
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59 and
lto front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
LOW SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the low posi-
tion, the BCM detects a low speed wiper ON request through the combination switch (wiper switch) reading
function.
The BCM then sends a front wiper (low) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When IPDM E/R receives front wiper (low) request signal, it supplies ground to energize the front wiper main
relay.
With the front wiper LOW/ HIGH relay energized, power is supplied
lthrough front wiper main relay
lthrough front wiper LOW/HIGH relay
lthrough IPDM E/R terminal 32
lto front wiper motor terminal 1.
Ground is supplied
lto front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the high posi-
tion, the BCM detects a high speed wiper ON request through the combination switch (wiper switch) reading
function.
The BCM then sends a front wiper (high) request signal with CAN communication.
lfrom BCM terminals 21 and 22
lto IPDM E/R terminals 39 and 40.
When IPDM E/R receives front wiper (high) request signal, it supplies ground to energize the front wiper main
relays.
With the front wiper LOW/HIGH relays energized, power is supplied
lthrough front wiper main relay
lthrough front wiper LOW/HIGH relay
lthrough IPDM E/R terminal 35
lto front wiper motor terminal 4.
Ground is supplied
lto front wiper motor terminal 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the front wiper motor operates at high speed.
