MULTI-REMOTE CONTROL SYSTEM
lthrough multi-remote control unit terminal 5
lto 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
lthrough multi-remote control unit terminal 6
lto 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
lLock operation: Flash once
lUnlock 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.
lIgnition switch (ON)
lSignal from remote controller
For detailed procedure, refer toBL-52, "
