+Door lock (and set super lock)
+Door unlock (and release super lock)
+Hazard reminder
LOCK OPERATIONNJEL0399S02To 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 OPERATIONNJEL0399S03When 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 REMINDERNJEL0399S04When the doors are locked or unlocked by multi-remote controller (signal from driver side unlock sensor),
supply power to hazard warning lamp flashes as follows
+Lock operation: Flash once
+Unlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRYNJEL0399S05A 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.
