FRONT WIPER AND WASHER SYSTEM
Revision: 2006 November2007 350Z
FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationNKS0051Z
System DescriptionNKS00520

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

to ignition relay, located in IPDM E/R, from battery direct

through 40 A fusible link [letter F, located in fuse, fusible link and relay box]

to BCM terminal 55,

through 10 A fuse [No.18 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]

to CPU (central processing unit) located in IPDM E/R,

through 10 A fuse [No.71 located in IPDM E/R]

to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied

to ignition relay, located in IPDM E/R,

through 10 A fuse [No.1 located in fuse block (J/B)]

to BCM terminal 38,

through ignition relay, located in IPDM E/R

to front wiper relay, located in IPDM E/R

to front wiper high relay, located in IPDM E/R

to CPU located in IPDM E/R,

through 10 A fuse [No.84 located in IPDM E/R]

through IPDM E/R terminal 44

REAR WIPER AND WASHER SYSTEM
Revision: 2006 November2007 350Z
3. CHECK REAR WIPER MOTOR SIGNAL
1. Connect BCM connector and rear wiper motor connector.
2. Turn ignition switch ON.
3. Check voltage between rear wiper motor harness connector ter-
minal and ground while rear wiper motor is stopped and while it
is operating.
OK or NG
OK >> Replace BCM. Refer to BCS-17, "Removal and Installation of BCM" .
NG >> Replace rear wiper motor. Refer to BCS-17, "
Removal and Installation of BCM" .
Only Rear Wiper ON Does Not OperateNKS00536
Refer to LT- 9 2 , "Combination Switch Inspection" .
Only Rear Wiper INT Does Not OperateNKS00537
Refer to LT- 9 2 , "Combination Switch Inspection" .
Wiper Does Not Wipe When Rear Washer OperatesNKS00538
Refer to LT- 9 2 , "Combination Switch Inspection" .
Rear Wiper Does Not StopNKS00539
1. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-III
1. Select “BCM” on CONSULT-III, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen. Make sure that “RR WIPER INT”, “RR
WIPER ON”, and “RR WASHER SW” turn ON-OFF according to wiper switch operation.
Without CONSULT-III
Refer to LT- 9 2 , "
Combination Switch Inspection" .
OK or NG
OK >> Replace BCM. Refer to BCS-17, "Removal and Installation of BCM" .
NG >> Check combination switch (wiper switch). Refer to LT- 9 2 , "
Combination Switch Inspection" .

Location
NKS0053A
REMOVAL
1. Turn rear wiper switch ON to operate wiper motor, and then turn rear wiper switch OFF (auto stop).
2. Remove rear wiper arm cap, and remove rear wiper arm nut.
3. Raise rear wiper arm, and remove rear wiper arm from the vehicle.
