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.

POWER DOOR LOCK
EL-207

System Description
OUTLINE
Power door lock system with super lock and key reminder is controlled by super lock control unit. Super lock
has a higher anti-theft performance than conventional power door lock systems.
When super lock is in released condition, lock knob operation locks or unlocks door.
When super lock is in set condition, lock knob operation cannot lock nor unlock door.
NOTE: Super lock function is not applied to back door. (Power door lock only)
OPERATION
Power door lock/unlock and super lock set/release operation by door key cylinder
+With the key inserted into front door key cylinder, turning it to LOCK will lock all doors and set super lock
while all doors are closed or one or more door is open. (Super lock will not be set while key is inserted
in the ignition key cylinder.)
+With the key inserted into front door key cylinder, turning it to UNLOCK will unlock all doors and release
super lock.
Power door lock/unlock and super lock set/release operation by multi-remote controller
+Pressing multi-remote controller LOCK button will lock all doors and set super lock while all doors are
closed and key is not inserted in the ignition key cylinder.
+Pressing multi-remote controller UNLOCK button will unlock all doors and release super lock with key not
inserted in the ignition key cylinder.
Power door lock and super lock release operation (by NATS IMMU signal)
+When the super lock is set, turning ignition key switch to ON will release super lock and unlock all doors.

Power door lock/unlock operation by lock knob
+With lock knob on driver or passenger door setting to LOCK while all doors are closed will lock all doors.
When one or more door is opened, with lock knob on passenger door setting to LOCK will lock
passenger door only. (Power door lock system will not operate.)
+With lock knob on driver or passenger door setting to UNLOCK while all doors are closed will unlock all
doors.
Lock knob operation cannot control super lock.
Key reminder system
+If the ignition key is in the ignition key cylinder and any door is open, setting lock/unlock switch or lock
knob on driver or passenger door to ``LOCK'' locks the door once but then immediately unlocks all doors.
System initialisation
+System initialisation is required when battery cables are reconnected. Conduct one of the followings to
release super lock once;
Ð insert the key into ignition key cylinder and turn it to ON.
