ID Code Entry Procedure
Note:
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.
Enter the identity (ID) code manually when:
lremote controller or control unit is replaced.
lan additional remote controller is activated.
To enter the ID code, follow the procedures below.
PROCEDURE
Close all doors and lock driver side door.
Insert and remove the key from the ignition more than seven times within 10 seconds.
Turn ignition key switch to ``ACC'' position. (The hazard warning lamps will then flash twice.)
Turn ignition key switch to ``OFF'' and remove the key from the ignition.
Push any button on the new remote controller once. (The hazard warning lamps will then flash
twice.)
At this time, the new ID code is entered and all previous ID memory is completely erased.
b
Do you want to enter any additional remote controller ID codes?
A maximum four ID codes may be entered. (After 4th ID code is entered, the registration
mode is ended.)
No Yes
ADDITIONAL ID CODE ENTRY
Release the door lock, then lock again with
driver side knob lock switch.
Open driver side door.
END.
After entering the identity (ID) code, check the operation of multi-remote control system.
NOTE:
lIf you need to activate more than two additional new remote controllers, repeat the procedure
``Additional ID code entry'' for each new remote controller.
lAny ID codes cannot be entered after termination of the ``setting mode''.

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.
