FRONT WIPER AND WASHER SYSTEM
Revision: 2004 November 2004 FX35/FX45
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 front wiper relay [located in IPDM E/R (intelligent power distribution module engine room)]
