FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationAKS0056O
System DescriptionAKS0056P

All front wiper relays (HI, LO) are included 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 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.
Power is supplied at all times

through 50 A fusible link (letter M, located in fusible link block)

to BCM (body control module) terminal 55

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) terminal 42

through 30 A fuse [No. 73, located in IPDM E/R (intelligent power distribution module engine room)]

to front wiper relay [located in IPDM E/R (intelligent power distribution module engine room)]

through 15 A fuse [No. 78, located in IPDM E/R (intelligent power distribution module engine room)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)]

through 10 A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)]

to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine
room)].
When the ignition switch ON or START position, power is supplied

through 15 A fuse [No. 1, located in fuse block (J/B)]

to BCM (body control module) terminal 38

through ignition relay [located in IPDM E/R (intelligent power distribution module engine room)]

to BCM (body control module) terminal 55

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) 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 (body control module) terminal 38,

through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]

to rear washer motor terminal 1.
Ground is supplied

to BCM (body control module) terminals 49 and 52

through grounds M35, M45 and M85

to combination switch (wiper switch) terminal 12

through grounds M35, M45 and M85.
REAR WIPER OPERATION
When wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch read-
ing function.
BCM operates rear wiper motor, power is supplied
