System Description
With ignition switch in ON or START position, power is supplied
+through 7.5A fuse [No.
8, located in the fuse block (J/B)]
+to power window relay terminalj
1.
The power window relay is energized and power is supplied
+through power window relay terminalj
5
+to power window main switch terminalj1,
+to power window sub switch terminalj
5.
MANUAL OPERATION
NOTE:
Numbers in parentheses are terminal numbers, when power window switch is pressed in the UP and DOWN
positions respectively.
Driver side
When the driver side switch in the power window main switch is pressed in the up position, power is supplied
+to driver side power window regulator terminal (j
2,j1)
+through power window main switch terminal (j
9,j8).
Ground is supplied
+to driver side power window regulator terminal (j
1,j2)
+through power window main switch terminal (j
8,j9).
Then, the motor raises or lowers the window until the switch is released.
Passenger side
MAIN SWITCH OPERATION
Power is supplied
+through power window main switch (j
5,j6)
+to front power window sub-switch (j
3,j4).
The subsequent operation is the same as the sub-switch operation.
SUB-SWITCH OPERATION
Power is supplied
+through front power window sub-switch (j
1,j2)
+to passenger side power window regulator (j
2,j1).
Ground is supplied
+to passenger side power window regulator (j
1,j2)
+through front power window sub-switch (j
2,j1)
+to front power window sub-switch (j
4,j3)
+through power window main switch (j
6,j5).
Then, the motor raises or lowers the window until the switch is released.
Rear door
Rear door windows will raise and lower in the same manner as passenger side door window.
AUTO OPERATION
The power window AUTO feature enables the driver to open or close the driver's window without holding the
window switch in the respective position.
When the AUTO switch in the main switch is pressed and released, the driver's window will travel to the fully
open or closed position.
POWER WINDOW LOCK
The power window lock is designed to lock operation of all windows except for driver's door window.
When the lock switch is pressed to lock position, ground of the sub-switches in the power window main switch
is disconnected. This prevents the power window motors from operating.

System Description
Power is supplied at all times
+through 40A fusible link (Letter
e, located in the fuse and fusible link box)
+to circuit breaker terminalj
1
+through circuit breaker terminalj2
+to smart entrance control unit terminalj11.
Ground is supplied to smart entrance control unit terminalj
18through body grounds.
INPUT
When the door lock & unlock switch (power window main switch) is in LOCKED position, ground signal is
supplied
+to smart entrance control unit terminalj
4
+through door lock & unlock switch terminalj14.
When the door lock & unlock switch (power window main switch) is in UNLOCKED position, ground signal is
supplied
+to smart entrance control unit terminalj
5
+through door lock & unlock switch terminalj7.
Driver side door key cylinder and driver side lock knob are connected to driver side door lock switch with a
rod. When driver side door lock switch is in UNLOCKED position, ground signal is supplied
+to smart entrance control unit terminalj
2
+through driver side door lock switch terminalj1(without multi-remote control system) or
+through driver side door lock actuator terminalj
2(with multi-remote control system).
When driver side door lock switch is in LOCKED position, ground signal is interrupted.
Door lock operates according to the conditions of the door lock & unlock switch (power window main switch)
and driver side door lock switch.
