MULTI-REMOTE CONTROL SYSTEM
System Description
EIS001RE
FUNCTION
Multi-remote control system has the following function.
●Door lock (and set super lock)
●Door unlock (and release super lock)
●Hazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the ignition switch must be at OFF.
When the LOCK signal is input to multi-remote control unit (the antenna of the system is combined with multi-
remote control unit), ground is supplied
●through multi-remote control unit terminal 5
●to time control unit terminal 32.
Then time control unit operates to lock doors and set super lock (models with super lock).
UNLOCK OPERATION
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
●through multi-remote control unit terminal 6
●to time control unit terminal 33.
Time control unit operates to unlock driver's door and release super lock (models with super lock).
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller (signal from driver side unlock sensor), sup-
ply power to hazard warning lamp flashes as follows
●Lock operation: Flash once
●Unlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
●Ignition switch (ON)
●Signal from remote controller
For detailed procedure, refer to BL-63, "
ID Code Entry Procedure" .

System DescriptionEIS001RR
NATS (Nissan Anti-Theft System) has the following immobilizer functions:
●Since 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.
●This version of NATS has dongle unit to improve its anti-theft performance (RHD models). Dongle unit has
its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initialization must be carried
out.
●When malfunction of dongle unit is detected:
The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.
–When dongle unit has a malfunction and the indicator lamp is illuminated, engine can not be started. How-
ever engine can be started only one time when security indicator lamp turns off in about 15 minutes after
ignition switch is turned to ON.
●All 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.
●The security indicator blinks when the ignition switch is in “OFF” or “ACC” position. Therefore, NATS
warns outsiders that the vehicle is equipped with the anti-theft system.
●When NATS detects trouble, the security indicator lamp lights up as follows.
●NATS trouble diagnoses, system initialization 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 initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
●When 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 from vehicle owner.
