System DescriptionNIS001WQ
Power is supplied at all times
through 50A fusible link (letter F , located in the fuse and fusible link box).
to BCM terminal 55,
through 10A fuse [No. 21, located in the fuse block (J/B)]
to BCM terminal 42.
When ignition switch is in ACC or ON position, power is supplied
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 11.
When ignition switch is in ON or START position, power is supplied
through 15A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38.
Ground is supplied
to BCM terminal 52
through body grounds M16 and M70.
When the door is locked or unlocked with power window main switch (door lock and unlock switch), ground is
supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 17
through grounds M16 and M70.
Then power window main switch (door lock and unlock switch) operation signal is sent.
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
When the door is locked or unlocked with power window sub-switch (front passenger side) (door lock and
unlock switch), ground is supplied
to CPU of power window sub-switch
through power window sub-switch (front passenger side) (door lock and unlock switch) terminal 11
through grounds M16 and M70.
Then power window sub-switch (front passenger side) (door lock and unlock switch) operation signal is sent
to BCM terminal 22
from power window sub-switch (front passenger side) (door lock and unlock switch) terminal 16.
When the door is locked with front door key cylinder switch (driver side), ground is supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 4
through front door key cylinder switch (driver side) terminals 6 and 4
through grounds M16 and M70.
Then front door key cylinder switch (driver side) operation signal (lock) is sent
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
When the door is unlocked with front door key cylinder switch (driver side), ground is supplied
to CPU of power window main switch
through power window main switch (door lock and unlock switch) terminal 6
through front door key cylinder switch (driver side) terminals 5 and 4
through grounds M16 and M70.
Then front door key cylinder switch (driver side) operation signal (unlock) is sent
to BCM terminal 22
from power window main switch (door lock and unlock switch) terminal 14
BCM is connected to power window main switch and power window sub-switch as serial link.

CAN Communication System DescriptionNIS001WR
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 UnitNIS001WS
Refer to LAN-34, "CAN Communication Unit" .
