ID Code Entry Procedure
Enter the identity (ID) code manually when:
Iremote controller or TCU is replaced.
Ian additional remote controller is activated.
Activation of the registration mode:
The vehicle must have been unlocked by either the multi-remote controller or a transponder OK signal (TPOK) from the vehicle's
immobilizer.
Preparation: - Make sure all doors unlock.
- Make sure all multi-remote controllers to be registered are available.
- Make sure the batteries of all multi-remote controllers are in a good condition.
- Make sure all transmitting sources are out of the neighbourhood of the vehicle.
- Make sure the battery of the vehicle is in a good condition.F
Switch ignition-switch exactly six times from the ªLOCKº to the ªONº position within 10 seconds and return the ignition switch to
the ªLOCKº position (leaving the key in the ignition switch).F
After 2 seconds the registration mode is activated. The turn signal lamps will flash twice.
OKNG
Proceed with the registration mode.
NOTE
The registration mode is exited when:IThe ignition-switch is turned to the ªONº position.
Ia multi-remote controller ID code had registered after 4 ID codes have been registered (then, all
of the registered ID codes are erased).
INo multi-remote controller or ignition switch input is received within 120 seconds.
Registration mode
G
Press and hold the ªUNLOCKº button of the multi-remote controller.F
NEL569
Press the ªLOCKº button 3 times.
Release the ªUNLOCKº button.
(At this time, the original (previous) ID code(s) are erased.)EIf the multi-remote controller code
is registered correctly, the turn
signal lamp will flash once.
(If 4 ID codes have been
registered, the turn signal lamp
will flash 3 times.)ENG
Do you want to register another multi-remote controller? (max. 4)
(If 4 controllers have been registered, you should turn the ignition switch to the
ON position.)
NoYe s
FOK
Turn the ignition switch to the ON position.
EIf the multi-remote controller reg-
istration is performed correctly,
the turn signal lamp will flash
twice.
(If 4 ID codes have been
registered, the turn signal lamp
will not flash.)
Take the ignition key out of the ignition switch and confirm the functioning of all
multi-remote controllers by locking and unlocking the vehicle with each of the
multi-remote controllers.OK NGF

MULTI-REMOTE CONTROL SYSTEM

System Description
NATS has the following immobiliser functions:
IThis version of NATS has dongle control unit to improve its anti-theft performance (RHD models). Dongle
control unit has its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization
must be carried out.
IWhen malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
Ð When dongle control unit has a malfunction, and the indicator lamp is illuminated, engine can not be
started. However engine can be started only one time when security indicator lamp turns off in about
15 minutes after ignition switch is turned to ON.
ISince only NATS ignition keys, whose ID nos. have been registered into the ECM and IMMU of NATS,
allow the engine to run, operation of a stolen vehicle without a NATS registered key is prevented by NATS.
That is to say, NATS will immobilize the engine if someone tries to start it without the registered key of
NATS.
IAll of the originally supplied ignition key IDs have been NATS registered.
If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-
nents.
IThe NATS security indicator (NATS security ind.) blinks when the ignition switch is in ªOFFº or ªACCº
position. Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
IWhen NATS detects trouble, the security indicator lamp lights up as follows.

INATS trouble diagnoses, system initialisation and additional registration of other NATS ignition key IDs
must be carried out using CONSULT-II hardware and CONSULT-II NATS software.
Regarding the procedures of NATS initialisation and NATS ignition key ID registration, refer to CONSULT-II
operation manual, NATS.
IWhen servicing a malfunction of the NATS (indicated by lighting up of security Indicator Lamp) or
registering another NATS ignition key ID no., it may be necessary to re-register original key iden-
tification. Therefore, be sure to receive all keys and the PIN code from vehicle owner.
