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.

Check Door Lock and Unlock Switch NIS001X0
1. CHECK POWER WINDOW SWITCH OUTPUT SIGNAL
With CONSULT-II
Check (“CDL LOCK SW ”, “CDL UNLOCK SW”) in DATA MONITOR mode with CONSULT-II.
Without CONSULT-II
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 >> Door lock and unlock switch is OK.
NG >> GO TO 2.
