System DescriptionEKS007F6
Both front wiper relays are located in 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 (body control module) when the wiper switch is
turned ON.
BCM controls front wiper LO, HI, and INT (intermittent) operation.
IPDM E/R operates the wiper motor according to CAN communication signals from the BCM.
Power is supplied at all times
to ignition relay, located in the IPDM E/R, and
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
