System Description
The multi-remote control system controls operation of the

power door lock (and super lock)
OPERATED PROCEDURE
Power door lock operation
When the following input signals are both supplied:

Key switch OFF (when ignition key is not inserted in key cylinder);

door switch CLOSED (when all the doors are closed);
The two above signals are already input into time control unit. At this point, time control unit receives a LOCK
signal from remote controller. Time control unit locks all doors and set super lock with input of LOCK signal
from remote controller.
When an UNLOCK signal is sent from remote controller once, driver’s door will be unlocked and release
super lock.
Then, if an UNLOCK signal is sent from remote controller again, all other door will be unlocked.
Multi-remote controller ID code entry
For detailed procedure, refer to“ID Code Entry Procedure”in EL-305.
