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.
