FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS00326
System DescriptionNKS00327

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
