System Description
FUNCTION
Multi-remote control system has the following function.
lDoor lock
lDoor unlock
lHazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder.)
lAll door switches CLOSED
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
lthrough multi-remote control unit terminalV10
lto smart entrance control unit terminalV4and
lto door lock relay terminalV6.
Then smart entrance control unit operates to lock doors (except for driver's door) and door lock relay ener-
gized to lock driver's door.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder)
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 terminalV11
lto smart entrance control unit terminalV5and
lto door lock relay terminalV5.
Then smart entrance control unit operates to unlock doors (except for driver's door) and door lock relay is
energized to unlock driver's door.
HAZARD REMINDER
When the doors and locked or unlocked by multi-remote controller, ground is supplied
lto terminalV1of multi-remote control relay-1 and 2
lthrough multi-remote control unit terminalV12.
Then the relays are energized and 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. Any attempt to enter a remote controller will erase
all ID codes previously entered. Therefore, be sure to receive all remote controllers from the vehicle owner
when any ID code entry is performed.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
lDriver side LOCKED signal (from driver side door unlock sensor)
lDoor switch CLOSED signal
lKey switch signal (INSERTED/WITHDRAWN)
lAccessory power supply
lSignal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-2139.
