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

After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
NKS0052J
CAUTION:
When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.
This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1. CHECK WIPER MOTOR SIGNAL
CONSULT-III DATA MONITOR
1. Select "WIP AUTO STOP" of BCM data monitor item.
2. make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper operation.
GO TO 2
OK or NG
OK >> Replace IPDM E/R. Refer to PG-26, "Removal and Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
