Check Power Window Serial LinkNIS00053
1. CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-III
Check door lock and unlock switch (“LOCK SW DR/AS”, “UNLK SW DR/AS”) in DATA MONITOR mode with
CONSULT-III. Refer to BL-35, "
DATA MONITOR" .
Without CONSULT-III
1. Remove key from ignition switch, and the door of driver side and passenger side is closed.
2. Check signal between BCM connector and ground with oscilloscope when door lock and unlock switch
(driver side and passenger side) is turned “LOCK” or “UNLOCK”.
3. Make sure signals which are shown in the figure below can be detected during 10 second just after door
lock and unlock switch (driver side and passenger side) is turned “LOCK” or “UNLOCK”.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK BCM OUTPUT SIGNAL
Check power window serial link (“POWER WINDOW DOWN”) in “ACTIVE TEST” mode with CONSULT-III.
Refer to BL-74, "
Active Test" .
When “ACTIVE TEST” is perform, is the window of driver side and passenger side lowered?
OK or NG
OK >> Further inspection is necessary. Refer to symptom chart.
NG >> Replace BCM.

REAR WINDOW DEFOGGER
Revision: 2006 November2007 350Z
REAR WINDOW DEFOGGERPFP:25350
Component Parts and Harness Connector LocationNIS0005C
System DescriptionNIS0005D
The rear window defogger system is controlled by BCM (Body Control Module) and IPDM E/R (Intelligent
Power Distribution Module Engine Room). The rear window defogger operates only for approximately 15 min-
utes.
Power is supplied at all times
through 20A fuse [No. 75 and 80, located in the IPDM E/R]
to rear window defogger relay terminal 3 and 6.
through 40A fusible link (letter F , located in the fuse and fusible link box)
to BCM terminal 55.
through 10A fuse [No. 18, located in the fuse block (J/B)]
to BCM terminal 42.
through 10A fuse [No. 19, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 21.
With the ignition switch turned to ON or START position, power is supplied
through 10A fuse [No. 1, located in the fuse block (J/B)]
to BCM terminal 38.
through 10A fuse [No. 12, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 22 and rear window defogger relay terminal 1
and then through unified meter and A/C amp.
to A/C controller (rear window defogger switch) terminal 72 and 84.
