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.)

: Program card
NATS (AEN00A)
4. Turn ignition switch ON.
5. Touch ªSTARTº.
6. Perform each diagnostic test mode according to each service

CONSULT-II DIAGNOSTIC TEST
MODEDescription
C/U INITIALIZATION When replacing any of the following components, C/U initialization is necessary.
[NATS ignition key/IMMU/ECM/Dongle]
SELF-DIAGNOSTIC RESULTS Detected items (screen terms) are as shown in the chart below.
NOTE:
When any initialisation is performed, all ID previously regis-
tered will be erased and all NATS ignition keys must be regis-
tered again.
The engine cannot be started with an unregistered key. In this
case, the system may show ªDIFFERENCE OF KEYº or ªLOCK
MODEº as a self-diagnostic result on the CONSULT-II screen.
When initialisation is performed for RHD models for Europe,
security indicator will flash six times to demonstrate recogni-
tion of dongle ID.
