Ground is supplied

to BCM terminal 52

through body grounds M30, and M66.

to unified meter and A/C amp. terminal 29 and 30

through body grounds M30 and M66.

to internal CPU of IPDM E/R terminal 38 and 60

through body grounds E17, E43, B102 (with VDC system or navigation system) and F152 (without VDC
system and navigation system).
When A/C controller (rear window defogger switch) is turned ON,
Rear window defogger switch signals are transmitted,

through A/C controller terminal 87

to unified meter and A/C amp.
Then ground is supplied

to BCM terminal 9

through unified meter and A/C amp. terminal 38

through unified meter and A/C amp. terminal 30

through body grounds M30 and M66.
Then BCM recognizes that rear window defogger switch is turned ON.
Then it sends rear window defogger switch signals to IPDM E/R via DATA LINE (CAN H, CAN L).
When IPDM E/R receives rear window defogger switch signals,
Ground is supplied

to rear window defogger relay terminal 2

through IPDM E/R terminal 52

through internal CPU of IPDM E/R

through IPDM E/R terminal 60

through body grounds E17, E43, B102 (with VDC system or navigation system), F152 (without VDC sys-
tem and navigation system), and then rear window defogger relay is energized.
When rear window defogger relay is turned ON,
Signals are transmitted

to rear window defogger terminal 1

through rear window defogger relay terminals 5 and 7 (For Coupe)

through rear window defogger relay terminal 5. (For Roadster)
Rear window defogger terminal 2 is grounded through body ground D212. (For Coupe)
Rear window defogger terminal 2 is grounded through body ground B5, B6 and T14. (For Roadster)
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned ON,
Power is supplied

through rear window defogger relay terminals 5 and 7 (For Coupe)

through rear window defogger relay terminal 7 (For Roadster)

through fuse block (J/B) terminal 2C

through 10A fuse [No. 8, located in the fuse block (J/B)]

through fuse block (J/B) terminal 5B

to door mirror defogger (Driver side and passenger side) terminal 2.
Door mirror defogger (Driver side and passenger side) terminal 1 is grounded through body grounds M30 and
M66.
With power and ground supplied, door mirror defogger filaments heat and defog the mirror.
When rear window defogger relay is turned ON,
Power is supplied

through rear window defogger relay terminals 5 and 7 (For Coupe)

through rear window defogger relay terminal 5. (For Roadster)

to unified meter and A/C amp. terminal 56
Then ground is supplied

Revision: 2006 November2007 350Z

to A/C controller terminal 78

through unified meter and A/C amp.

through unified meter and A/C amp. terminal 29 and 30

through body grounds M30 and M66.
This energizes rear window defogger indicator.
CAN Communication System DescriptionNIS0005E
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0005F
Refer to LAN-48, "CAN System Specification Chart" .
