System Description
FUNCTION
Multi-remote control system has the following function.
+Door lock
+Door unlock
+Hazard reminder
LOCK OPERATION
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
V5
+to smart entrance control unit terminalV4.
Then smart entrance control unit supplies power and ground to each door lock actuator.
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
V6
+to smart entrance control unit terminalV5.
Then smart entrance control unit supplies power and ground to each door lock actuator.
HAZARD REMINDER
When the doors are locked or unlocked (signal from driver's door unlock sensor) by multi-remote controller,
power is supplied
+through multi-remote control unit terminals
V3andV8
+to the hazard warning lamps
Then hazard warning lamp flash as follows.
+Lock operation: Flash once
+Unlock 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.
+Ignition switch ON signal
+Battery power supply
+Signal from remote controller
For detailed procedure, refer to ªID Code Entry Procedureº in EL-3139.

ID Code Entry Procedure
Activation of the registration mode:
The vehicle must have been unlocked by either the multi-remote controller or a transponder OK signal (TPOK)
from the vehicle's immobilizer.
Preparation: - Make sure all doors unlock.
- Make sure all multi-remote controllers to be registered are available.
- Make sure the batteries of all multi-remote controllers are in a good condition.
- Make sure all transmitting sources are out of the neighbourhood of the vehicle.
- Make sure the battery of the vehicle is in a good condition.b
Switch ignition-switch exactly six times from the ªLOCKº to the ªONº position within 10 seconds and return the
ignition switch to the ªLOCKº position (leaving the key in the ignition switch).b
After 2 seconds the registration mode is activated. The turn signal lamps will flash twice.
OKNG
Proceed with the registration mode.
NOTE
The registration mode is operated when:+The ignition-switch is turned to the ªONº position.
+4 multi remote controllers have been learned.
+No multi-remote controller or ignition switch input is received within 120 sec-
onds.
Registration mode
Press and hold the ªUNLOCKº button of the multi-remote controller.b
Press the ªLOCKº button 3 times.
Release the ªUNLOCKº button.cIf the multi-remote controller
code is registered correctly,
the turn signal lamp will flash
once.cNG
Do you want to register another multi-remote controller? (max. 4)

m
After registration of the requested No. of multi-remote controller(s),
confirm the ID-code(s) by switching the ignition switch to the ªONº
position.cIf the multi-remote controller
registration is performed
correctly, the turn signal lamp
will flash twice.
Take the ignition key out of the ignition switch and confirm the func-
tioning of all multi-remote controllers by locking and unlocking the
vehicle with each of the multi-remote controllers.b
