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
