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 the released condition, lock knob operation locks or unlocks door.
When super lock is in set condition, lock knob operation cannot lock nor unlock door.
OPERATION
Power door lock/unlock and super lock set/release operation by door key cylinder
IWith the key inserted into door key cylinder on driver or passenger door, turning it to LOCK will lock all
doors and set super lock while all doors are closed or one or more door is open.
IWith the key inserted into door key cylinder on driver or passenger door, turning it to UNLOCK will unlock
all doors and release super lock.
Power door lock and super lock release operation (by NATS IMMU signal)
IWith the key inserted in ignition key cylinder and turning it to ªONº for about5-6sec. will unlock all doors
and release super lock.
Power door lock/unlock operation by lock knob
ISetting lock knob on driver or passenger door to LOCK while all doors are closed, will cause all doors to
lock.
Setting lock knob on passenger door to lock when one or more doors are open will lock passen-
ger door only. (Power door lock system will not operate.)
ISetting lock knob on driver or passenger door to UNLOCK while all doors are closed will unlock all doors.
Lock knob operation cannot control super lock.

knob on driver door to ªLOCKº locks the door once but then immediately unlocks it.
System initialisation
ISystem initialisation is required when battery cables are reconnected. Conduct one of the following:
Ð insert the key into ignition key cylinder and turn it to ªON.º
Ð LOCK/UNLOCK operation using door key cylinder.

Trouble Diagnoses
If doors can not be unlocked by remote controller operation then the following procedure is required.
A) Unlock the vehicle by a mechanical key in the drivers door key cylinder.
Note: this may cause the alarm to sound.
B) Put the key in ignition, turn to ON position for at least five seconds. Assuming the ignition key contains a
valid transponder then a signal will be generated by the immobilizer which will disarm the alarm and allow
key learn mode to be entered.
C) Turn ignition OFF and wait for ten seconds.
