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)]

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

through IPDM E/R (intelligent power distribution module engine room) terminal 44

to front washer motor terminal 1.
Ground is supplied

to BCM terminals 49 and 52

through grounds M35, M45 and M85

to IPDM E/R terminals 38 and 60

through grounds E21, E50 and E51

to combination switch (wiper switch) terminal 12

through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When wiper switch is in LO position, BCM detects low speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (LO) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay (located in IPDM E/R),
power is supplied

to front wiper motor terminal 1

through IPDM E/R terminal 21 and front wiper relay and front wiper HI relay.
Ground is supplied

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed.
HI SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (HI) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied

to front wiper motor terminal 4

through IPDM E/R terminal 31 and front wiper relay and front wiper HI relay.
Ground is supplied

to front wiper motor terminal 2

through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from a combination of 3 switches (intermittent opera-
tion dial position 1, intermittent operation dial position 2, and intermittent operation dial position 3) and vehicle
speed signal.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

Inspection Procedure
1. CHECK FUSE

Check if wiper and washer fuse is blown.
Refer to WW-11, "Wiring Diagram — WIPER —" .
OK or NG
OK >> GO TO 2
NG >> If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse. Refer to PG-
3, "POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector terminal and
ground.
OK or NG
OK >> GO TO 3.
NG >> Check harness for open or short between fuse, fusible link and BCM.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector M4 terminals 49
