Operation

OPERATING PROCEDURE
The multi-remote control system controls operation of the
^ power door lock
^ power window
^ hazard reminder
^ trunk lid opener
^ panic alarm
Multi-remote control unit (LCU05) can receive signals from remote controller when key switch is in OFF position (key not in cylinder). And it sends the signals to BCM and LCUs as DATA LINES A-1 or A-2.

Power door lock operation
^ Key switch OFF signal (ignition key is not in key cylinder)
^ Door switch CLOSE signal (all doors closed)
The two above signals are already input into BCM. At this point, multi-remote control unit receives a LOCK signal from remote controller. Multi-remote control unit (LCU05) will then send a LOCK signal to BCM via DATA LINE A-1.
When an UNLOCK signal is sent from remote controller, door lock actuators unlock all doors and interior lamp illuminates if interior lamp switch is in DOOR position.
For detailed description, refer to "POWER DOOR LOCK - IVMS".

Power window operation
When an UNLOCK signal from remote controller is input into multi-remote control unit (LCU05) continuously more than 1.5 seconds, front power windows lower the windows.

Hazard reminder
Power is supplied at all times
^ through 10 A fuse [No. (11), located in the fuse block (J/B)]
^ to multi-remote control relay-1 terminals (1), (3) and (6).
When multi-remote control unit (LCU05) receives a LOCK signal, ground is supplied
^ to multi-remote control relay-1 terminal (2)
^ through BCM terminal (18).
Multi-remote control relay is now energized and door lock actuators lock all doors. (Hazard warning lamps flash twice as a reminder.)

Trunk lid opener operation
Power is supplied at all times
^ through 15 A fuse [No. (37) ,located in the fuse block (J/B)]
^ to trunk lid opener actuator terminal (2).
When TRUNK OPEN signal is sent from remote controller, ground is supplied
^ to trunk lid opener actuator terminal (1)
^ through multi-remote control unit (LCU05) terminal (5)
When power and ground are supplied, trunk lid opener actuator opens trunk lid.

Panic alarm operation
Multi-remote control system activates horn and headlamps intermittently when an alarm signal is sent from remote controller to multi-remote control system.
