All front wiper relays (HI, LO) are included in IPDM E/R (intelligent power distribution module engine
room).
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.
OUT LINE
Power is supplied at all times
through 50 A fusible link (letter M, located in fuse, fusible link and relay box.)
to BCM terminal 55,
through 15 A fuse [No. 22, located in fuse block (J/B)]
to BCM terminal 42,
through 30 A fuse (No. 73, located in IPDM E/R)
to front wiper relay, located in IPDM E/R,
through 15 A fuse (No. 78, located in IPDM E/R) and
through 10 A fuse (No. 71, located in IPDM E/R)
to CPU located in IPDM E/R.
When the ignition switch is ON or START position, power is supplied
to ignition relay located in IPDM E/R, from battery direct,
through 15 A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38,
through ignition relay, located in IPDM E/R

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 rear wiper ON and INT (intermittent) operation.
Power supplied at all times
through 50 A fusible link (letter M, located in fuse, fusible link and relay box)
to BCM terminal 55,
through 15 A fuse [No. 22, located in fuse block (J/B)]
to BCM terminal 42.
When ignition switch ON or START position, power is supplied
through 15 A fuse [No.1, located in fuse block (J/B)]
to BCM terminal 38,
through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]
to combination switch terminal 14.
Ground is supplied
to BCM terminals 49 and 52
through grounds M35, M45 and M85,
to combination switch terminal 12
through grounds M35, M45 and M85.
REAR WIPER OPERATION
When the wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch
reading function.
BCM operates rear wiper motor, power is supplied
